Title: Adjustment device of grinding machine capable of grinding workpiece in seven-axis directions

Description:
FIELD OF THE INVENTION 
     The present invention relates to an adjustment device of a grinding machine which contains a first system and a second system interacted with the first system so that the first system and the second system are moved in seven-axis directions. 
     BACKGROUND OF THE INVENTION 
     Conventional automatic computer program control machines (such as CNC grinding machines) cannot grind workpieces at any desired angles. 
     For example, a grind device of the grinding machines is too simplified to grind the workpieces in multiple axis directions and cannot be controlled in a computer numerical control manner. Even though the grinding machines are controlled in the CNC control manner, the tools are expensive and cannot be adjustably moved to a desired angle accurately. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. 
     SUMMARY OF THE INVENTION 
     The primary aspect of the present invention is to provide an adjustment device of a grinding machine which contains a first system and a second system interacted with the first system so that the first system and the second system are moved in seven-axis directions. 
     An adjustment device of a grinding machine contains: a first system and a second system. The first system is a grinding unit, and the second system is a tool fixing unit. The grinding unit and the tool fixing unit are mounted on a base of the grinding machine. 
     The grinding unit includes a first guide rail and a second guide rail on which the grinding unit is driven to move in a first X-axis direction and a first Y-axis direction of the base. 
     The tool fixing unit includes a horizontal rotation mechanism mounted on the base parallel to a first XY plane, a locating portion, a third guide rail arranged on a rotation disc of the horizontal rotation mechanism and configured to move the tool fixing unit in a second X-axis direction of the base, a fourth guide rail arranged above the third guide rail and configured to move the tool fixing unit in a second Y-axis direction of the base, and a fifth guide rail arranged above the fourth guide rail and configured to move the tool fixing unit in a Z-axis direction of the base. 
     The locating portion is cylindrical, parallel to a second XY plane, and has a rotation axis defined on a center of the locating portion, such that the locating portion rotates along the rotation axis and a tool is positioned on the locating portion to rotatably grind the workpiece at different angles.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to  FIG. 1 , an adjustment device of a grinding machine capable of grinding a workpiece (not shown) in seven-axis directions according to a preferred embodiment of the present invention comprises: a first system and a second system interacted with the first system so that the first system and the second system are moved in the seven-axis directions. 
     The first system is a grinding unit  1 , and the second system is a tool fixing unit  2 , wherein the grinding unit  1  and the tool fixing unit  2  are mounted on a base  10  of the grinding machine, the grinding unit  1  includes multiple first grind wheels  11  horizontally arranged thereon, multiple second grind wheels  12  vertically arranged on the grinding unit  1 , a first guide rail  13  and a second guide rail  14  on which the grinding unit  1  is driven to move in a first X-axis direction and a first Y-axis direction of the base  10 . 
     The tool fixing unit  2  includes a horizontal rotation mechanism  21  mounted on the base  10  parallel to a first XY plane, a locating portion  23 , a third guide rail  25  arranged on a rotation disc  22  of the horizontal rotation mechanism  21  and configured to move the tool fixing unit  2  in a second X-axis direction of the base  10 , a fourth guide rail  26  arranged above the third guide rail  25  and configured to move the tool fixing unit  2  in a second Y-axis direction of the base  10 , and a fifth guide rail  27  arranged above the fourth guide rail  26  and configured to move the tool fixing unit  2  in a Z-axis direction of the base  10 . The locating portion  23  is cylindrical, parallel to a second XY plane, and has a rotation axis  24  defined on a center of the locating portion  23 , such that the locating portion  23  rotates along the rotation axis  24  and a tool  3  is positioned on the locating portion  23  to rotatably grind the workpiece at different angles. 
     Referring to  FIGS. 1-3 , the rotation disc  22  has a central axis C defined on a center thereof, when the tool  3  of the locating portion  23  is changeably moved to different horizontal angles, the rotation disc  22  of the horizontal rotation mechanism  21  is driven to revolve along the central axis C so that the locating portion  23  is positioned at a desired angle after rotating vertically parallel to a Z axis along the central axis C of the rotation disc  22 , as illustrated in  FIG. 3 . 
     As shown in  FIG. 4 , when the tool  3  of the locating portion  23  is adjustably moved to a desired height in the Z-axis direction of the base  10 , the locating portion  23  is driven to move on the fifth guide rail  27  of the tool fixing unit  2 . 
     Thereby, the grinding unit  1  and the tool fixing unit  2  are adjustably moved in the seven-axis directions to grind the workpiece along the rotation axis  24  by ways of the first guide rail  13 , the second guide rail  14 , the third guide rail  25 , the fourth guide rail  26 , the fifth guide rail  27 , the horizontal rotation mechanism  21 , and the locating portion  23 . The adjustment device is control to move and rotate in a computer numerical control manner and by a motor, and the computer numerical control manner and the motor are a well-known art, further remarks are omitted. 
     Accordingly, the grinding unit  1  and the tool fixing unit  2  are adjustably moved in the seven-axis directions to grind the workpiece. The grinding unit  1  includes the multiple first grind wheels  11  horizontally arranged thereon and the multiple second grind wheels  12  vertically arranged on the grinding unit  1 , and the grinding unit  1  is driven to move in the first X-axis direction and the first Y-axis direction of the base  10 . The locating portion  23  of the tool fixing unit  2  moves in the second X-axis direction, the second Y-axis direction, and the Z-axis direction of the base  10 , and the locating portion  23  is fixed on the rotation disc  22  of the horizontal rotation mechanism  21  parallel to the second XY plane and rotates along the rotation axis  24  so that the tool is moved in the seven-axis directions, and the locating portion  23  is rotated to the desired angle, thus grinding the workpiece accurately and quickly. 
     While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
