The receiving case 50 has a base wall 51, a top wall 52, a front wall 54, a rear wall 55 and two sidewalls 56. Two accommodating holes 53 are defined on the base wall 51 and the top wall 52 respectively, and axle centers of the two accommodating holes 53 are on the same vertical line. The rear wall 55 is cut partly to form a mounting opening 57 where the supporting board 26 of the first cylinder module 20 is located. A through-hole 58 is defined and passes through one sidewall 56. Four pads 59 are mounted at four corners of a bottom surface of the base wall 51 for supporting the receiving case 50.
Please refer to FIG. 1, FIG. 3 and FIG. 4. The second cylinder module 60 assembled in the receiving case 50 includes a second cylinder body 61. The second cylinder body 61 is integrated with a fixing frame 62 at a side thereof. Both the second cylinder body 61 and the fixing frame 62 are seated on the base wall 51 of the receiving case 50. A second connecting pillar 63 is inserted in the through-hole 58 of the receiving case 50 and passes through the second cylinder body 61 and the fixing frame 62 horizontally. One end of the second connecting pillar 63 connects with a second adjusting nut 40 exposing out of the receiving case 50 for adjusting the travel thereof. The other end of the second connecting pillar 63 defines an aperture (not shown) therein.
The rotating module 70 received in the receiving case 50 includes a cylindrical rotatable shaft 73 disposed vertically. The rotatable shaft 73 runs through the top wall 52 and the base wall 51 and is received in the accommodating holes 53. A bottom end of the rotatable shaft 73 inserted in the accommodating hole 53 defined on the base wall 51 is surrounded with a bearing 75 to drive the rotatable shaft 73 rotating. A top end of the rotatable shaft 73 engages with a circular salver 71. The salver 71 is disposed on a top surface of the top wall 52 of the receiving case 50. The brim of the salver 71 defines a position opening 72. A gear wheel 74 is located around a substantial center of the rotatable shaft 73 and below the salver 71. A long strip rack 76 meshed with the gear wheel 74 has a connect portion (not shown) to be inserted in the aperture of the connecting pillar 63. The rack 76 is slidably received in a holding frame 77 and is supported via the holding frame 77 located on the base wall 51 of the receiving case 50.
The circuit box 90 is fabricated above the top wall 52 of the receiving case 50. The circuit box 90 connects with the first cylinder module 20 and the second cylinder module 60 respectively to control the operation time and motions of the first cylinder module 20 and the second cylinder module 60. The two controlling switches 80 are mounted on both sides of the front wall 54 of the receiving case 50 respectively to start the first cylinder module 20 and the second cylinder module 60.
Please refer to FIG. 5 showing a kind of product 200 that needs to be tested. The product 200 has a restraining portion 201. Four limiting cavities 203 are defined on the restraining portion 201 and distributed symmetrically. An active portion 202 which is in circular ring shape is disposed at the bottom of the restraining portion 201. A position portion 204 extends outward form the bottom of the restraining portion 201.
Please refer to FIG. 1 and FIG. 5. When the rotating machine 100 is used for testing the rotational property of the product 200, firstly put the product 200 on the salver 71 of the rotating module 70 and the position portion 204 of the product 200 is located in the position opening 72. Then, press the controlling switches 80 to start the first cylinder module 20 and the second cylinder module 60. The circuit box 90 controls the operation time and the motions of the first cylinder module 20 and the second cylinder module 60. The first cylinder module 20 moves downward and makes the four grappling hooks 30 insert in the four limiting cavities 203 of the product 200 correspondingly to locate the restraining portion 201 in the salver 71. Subsequently, the second cylinder module 60 begins to work and brings the long strip rack 76 to move. The long strip rack 76 drives the gear wheel 74 that meshes with the long strip rack 76 rotating in an appointed direction. Because the gear wheel 74 is located around the rotatable shaft 73, the rotatable shaft 73 and the salver 71 follow the gear wheel 74 to rotate in the same direction as the gear wheel 74. So, the active portion 202 of the product 200 is driven rotating relatively to the restraining portion 201. When the salver 71 rotates at a particular portion, the gear wheel 74 stops rotating and then rotates in an opposite direction. At this time, the first cylinder module 20 rises and makes the four grappling hooks 30 depart from the product 200. Afterwards, the product 200 is taken away from the salver 71 to finish being tested, and then, another product 200 is put on the salver 71 to be tested.
As described above, the rotating machine 100 is easy and safe to operate. Meanwhile, the rotating machine 100 makes the active portion 202 of the product 200 rotate fully, ensuing the quality of the product 200. Additionally, the rotating machine 100 can test different kinds of products just through changing the corresponding salver 71 of the rotating module 70 and the grappling hooks 30, increasing the practicality of the rotating machine 100.
