BACKGROUND OF THE INVENTION The present invention generally relates to a pallet changer and a system and a method for using the same. More specifically, the present invention relates to a pallet changer and a system and a method for using the same which may attach, may connect and/or may secure a pallet assembly to a receiver assembly for inserting into a machine compartment. The pallet assembly may have a base with an arm, a groove and/or a pull post for inserting into the receiver assembly. The pull post of the pallet assembly may have a first tapering for inserting between a first wedge arm and a second wedge arm of the receiver assembly. The first tapering on the pull post may correspond to and/or may match a second tapering on the first wedge arm and/or the second wedge arm. Springs of the receiver assembly may apply a force to the first wedge arm and/or the second wedge arm to attach and/or to connect the pallet assembly to the receiver assembly. The receiver assembly may have a cam which may be mechanically connected to the first wedge arm and/or the second wedge arm. The cam may be moved to and/or may be rotated to an open position to move the first wedge arm outwardly with respect to the second wedge arm for inserting or for removing the arm and/or the pull post of the pallet assembly from the receiver assembly. The cam may be moved and/or may be rotated to a closed position to move the first wedge arm inwardly with respect to the second wedge arm for connecting, for attaching and/or for securing the arm and/or the pull post of the pallet assembly to the receiver assembly. A first plate may be attached to the receiver assembly to prevent movement and/or rotation of the first wedge arm and/or the second wedge arm with respect to the receiver assembly. A second plate may be connected to a passage in the receiver assembly for preventing movement of the cam between the open position and the closed position. It is generally known to provide a pallet changer to insert and to remove a part from a machine compartment for machining of the part. The part is attached to a removable plate of the pallet changer for inserting and for removing the part with respect to the machine compartment. The removable plate of the pallet changer is inserted into, is connected to, is attached to and/or is secured to a base unit and/or a roller unit. The base unit and/or the roller unit is moved from a first position to a second position for inserting and/or for removing the removable plate and/or the part with respect to the machine compartment. Traditionally, air lines and/or electrical lines are attached to and/or are connected to a removable plate, the base unit and/or the roller unit to connect the removable plate and/or the part to the base unit and/or the roller unit. The air lines and/or the electrical lines limits movement of the pallet assembly with respect to the machine compartment and/or the roller assembly. Electrical switches are attached to and/or are connected to the pallet changer to confirm that the removable plate and/or the part is attached to and/or is secured to the base unit and/or the roller unit. The part is not machined and/or is not moved within the machine compartment without confirmation and/or without signaling from the electrical switches. After the removable plate and the part are inserted into the machine compartment and the electrical switches confirm that the removable plate and the part are secured, the removable plate, the base unit, the roller unit and/or the part moves along a first axis, a second axis and/or a third axis inside the machine compartment for machining the part. The first axis permits the removable plate and the part to move between a left end and a right end of the machine compartment for machining the part. The second axis permits the removable plate and the part to move between a rear end and a front end of the machine compartment for machining the part. The third axis permits the removable plate and the part to move between a top end and a bottom end of the machine compartment for machining the part. The air lines and/or the electrical lines attached to the pallet changer limits the movement of the part to two-axis movement which includes the first axis and the second axis or to three-axis movement which includes the first axis, the second axis and the third axis inside the machine compartment. Further, the electrical switches of the pallet changer may limit the movement of the part to the two-axis movement or the three-axis movement inside the machine compartment. However, the part may require four-axis movement or five-axis movement inside the machine compartment for machining the part. A fourth axis of the four-axis movement permits an end of the part to move and/or to rotate in a clockwise direction or a counter-clockwise direction with respect to a center of the part or a center of the removable plate for machining the part. A fifth axis of the five-axis movement permits the removable plate and the part to move in a swing-like movement inside the machine compartment for machining the part. Still further, the machine compartment may have a height which may be less than the height of the pallet changer. As a result, the pallet changer and the part may be incapable of being inserted into the machine compartment for machining the part. A need, therefore, exists for a pallet changer and a system and a method for using the same which may attach and/or may secure a pallet assembly to a receiver assembly for machining a part without air lines, without electrical lines and/or electrical switches. Further, a need exists for a pallet changer and a system and a method for using the same which may be receivable by and/or insertable into a machine compartment for machining a part on the pallet changer. Still further, a need exists for a pallet changer and a system and a method for using the same which may provide for movement of the pallet changer and/or a part attached to the pallet changer in a four-axis movement or a five-axis movement within a machine compartment for machining the part. Moreover, a need exists for a pallet changer and a system and a method for using the same which may provide wedge arms, springs, a groove and/or a pull post to connect, to attach and/or to secure a pallet assembly to a receiver assembly and/or a surface of a machine. Furthermore, a need exists for a pallet changer and a system and a method for using the same which may provide a cam, a first plate and/or a second plate for moving wedge arms of a receiver assembly between an open position and a closed position to attach and/or to separate a pallet assembly and the receiver assembly.

As a result, the pallet assembly 20 and/or the part 12 may be secured to, may be attached to and/or may be connected to the receiver assembly 100 and/or the machine 13 with the receiver assembly 100 in the locked position. The key 200 may be separated from and/or may be removed from the head 130 of the shaft 128 with the receiver assembly 100 in the locked position. The key 200 may be removed from the lock plate 108 and the passage 106 of the receiver assembly 100 with the receiver assembly 100 in the locked position. The receiver assembly 100, the pallet assembly 20, the part 12 and/or the machine 13 may be inserted into and/or may be positioned inside the machine compartment with the receiver assembly 100 in the locked position. Doors (not shown in the figures) to the machine compartment may be moved from an open position to a closed position for securing the part 12, the pallet assembly 20, the receiver assembly 100 and/or the machine 13 inside the machine compartment for machining the part 12. As a result, the part 12, the pallet assembly 20, the receiver assembly 100 and/or the machine 13 may be enclosed inside the machine compartment with the doors in the closed position. The part 12 may be machined inside and/or may be moved inside the machine compartment via the machine 13 with the receiver assembly 100 in the locked position. As a result, the part 12 may be secured to, may be attached to and/or may be connected to the receiver assembly 100 and/or the machine 13 as the tool may machine the part 12 inside the machine compartment. Machining of the part 12 via the tool may require the part 12 to be moved along the first axis, the second axis, the third axis, the fourth axis and/or the fifth axis inside the machine compartment. The part 12, the machine 13, the receiver assembly 100 and/or the pallet assembly 20 may move along the first axis, the second axis, the third axis, the fourth axis and/or the fifth axis inside the machine compartment for machining the part 12. As a result, the part 12 may move in the two-axis movement, the three-axis movement, the four-axis movement or the five-axis movement inside the machine compartment for machining the part 12 with the tool. The part 12 which may have been machined by the tool may be removed from the machine compartment via the machine 13, the pallet assembly 20 and/or the receiver assembly 100. The doors of the machine compartment may be moved from the closed position to the open position to permit the part 12, the machine 13, the pallet assembly 20 and/or the receiver assembly 100 to be removed from the machine compartment. The key 200 may be inserted between the lock plate 108 and the passage 106 of the receiver assembly 100 to engage and/or to abut the head 130 of the shaft 128. The key 200 may be move and/or may be rotated in the clockwise direction or in the counter-clockwise direction to move the receiver assembly 100 from the locked position to the unlocked position. The cam 126 may move and/or may rotate in the clockwise direction or in the counter-clockwise direction to move the second end 129 of the cam between the wedge arms 114 a, 114 b. As a result, the wedge arms 114 a, 114 b may move outwardly with respect to each other for moving the receiver assembly 100 from the locked position to the unlocked position. The arm 24 and/or the pull post 26 of the pallet assembly may be removed from and/or may be separated from the opening 110 and/or the wedge arms 114 a, 114 b of the receiver assembly 100. As a result, the part 12 and/or the pallet assembly 20 may be separated from and/or may be removed from the receiver assembly 100 with the receiver assembly 100 in the unlocked position. The system 10 may attach, may secure and/or may connect the part 12 and/or the pallet assembly 20 to the receiver assembly 100 for machining the part 12. The groove 38 and/or the pull post 26 of the pallet assembly 20 may be inserted between the wedge arms 114 a, 114 b of the receiver assembly 100. The springs 122 a, 122 b of the receiver assembly 100 may exert and/or may apply the first force and the second force, respectively, against the wedge arm 114 a, 114 b. The key 200 and/or the cam 126 may move and/or may rotate to move the wedge arms 114 a, 114 b and/or the receiver assembly 100 between the locked position and the unlocked position. The first tapering 40 of the pallet assembly 20 may engage and/or may correspond to the second tapering 117 of the wedge arms 114 a, 114 b to lock, to secure, to attach and/or to connect the pallet assembly 20 to the receiver assembly 100 in the locked position. The plate 134 of the receiver assembly 100 may prevent the cam 126 from rotating the first wedge arm 114 a within the compartment 115 of the receiver assembly 100. The lock plate 108 may prevent the key 200 from being removed from and/or from being separated from the receiver assembly 100 in the unlocked position.
