[0023] Please refer to Figures 1 to 6 , the present utility model provides a workpiece processing center, including an outer cover 200, a fixture 100 and a processing device. The fixture 100 and the processing device are disposed inside the outer cover 200, and the outer cover 200 is provided with a functional port for installing the workpiece and for adjusting the position of the fixture 100.

[0024] The fixture 100 includes a first clamping device 10 and a second clamping device 20 of the body. The first clamping device 10 and the second clamping device 20 are arranged oppositely. The first clamping device 10 and the second clamping device 20 cooperate to clamp the workpiece and drive the workpiece to rotate and adjust the position, so that the processing device can process different sides of the workpiece.

[0025] The first clamping device 10 includes a chassis 11, a positioning plate 13 and a guide shaft 12 installed on the chassis 11, a slider 14 slidably disposed on the guide shaft 12, a connecting plate 15 installed on the slider 14, a clamping box 16 installed on the connecting plate 15, a first chuck 17 installed on the clamping box 16, a first bushing 18 installed on the positioning plate 13, and a pressure rod 19 passing through the positioning plate 13 and the first bushing 18 and threadedly installed with the first bushing 18. In this embodiment, the positioning plate 13 is installed at one side position of the chassis 11, and the pressure rod 19 is disposed at the rear position of the connecting plate 15. When the pressure rod 19 is adjusted forward, the pressure rod 19 squeezes the connecting plate 15 forward.

[0026] The first bushing 18 is provided with a perforation distributed along its axial direction, and the perforation is provided with internal threads. The pressing rod 19 includes a main body section 191, a side pressing section 192 connected to one end of the main body section 191, and a handle section 193 connected to the other end of the main body section. External threads are provided on the main body section 191. During assembly, the main body section of the pressing rod 19 passes through the positioning plate 13 and the first bushing 18 at the same time, and the main body section 191 is installed by fitting the external threads with the internal threads of the perforation on the first bushing 18. Moreover, the side pressing section 192 is arranged on the side close to the connecting plate 15. By rotating the handle section 193, the entire pressing rod 19 is displaced forward or backward at the mating zone of the external threads of the main body section 191 and the external threads of the first bushing 18.

[0027] It can be understood that in this embodiment, the pressing rod 19 is manually driven to adjust its position in the form of the handle section 193. In other embodiments, a gear set and a motor that mesh with each other can also be provided. The gear set is connected to the motor and the main body section 191 of the pressing rod 19, and the motor drives the pressing rod 19 to rotate through the gear set.

[0028] The first chuck 17 includes a bearing 171 and a chuck body 172. The bearing 171 is installed in the material clamping box 16. One end of the chuck body 172 is installed on the inner ring of the bearing 171, and the other end of the chuck body 172 extends out of the material clamping box 16. The chuck body 172 can rotate around the axis of the bearing 171.

[0029] The second material clamping device 20 includes a support plate 21 opposite to the first chuck 17, a fixed seat 22 installed on one side of the support plate 21, a functional plate 23 installed on the other side of the support plate 21, a second bushing 28 installed on the fixed seat 22 and extending into the support plate 21, a positioning frame 24 installed on the support plate 21 on the side of the second bushing 28, a driving motor 25 installed on the positioning frame 24, a second chuck 26 extending horizontally from the functional plate 23, and a linkage rod 27 connecting the second chuck 26 and the driving motor 25. One end of the second chuck 26 is arranged opposite to the first chuck 17 in the horizontal direction, and the other end of the second chuck 26 is arranged opposite to the driving motor 25 in the horizontal direction. One end of the linkage rod 27 extends into the functional plate 23 and is connected to the second chuck 26, and the other end of the linkage rod 27 extends out of the second bushing 28 and is connected to the driving motor 25.

[0030] Before processing, the workpiece is first fixed on the fixture 100. When fixing, the workpiece is set between the first chuck 17 and the second chuck 26. Rotate the handle part 193 to make the entire pressure rod 19 push forward against and drive the slider 14 to shift forward. During the movement of the slider 14, it drives the chuck body 172 of the first chuck 17 to move towards the second chuck 26, clamping the workpiece between the chuck body 172 of the first chuck 17 and the second chuck 26. During processing, the drive motor 25 drives the second chuck 26 to rotate through the linkage rod 27. During the rotation of the second chuck 26, it drives the workpiece and the chuck body 172 to rotate synchronously, thereby driving the workpiece to rotate circumferentially.

[0031] The beneficial effects of the workpiece processing center of the present utility model are as follows: By providing a slider 14 slidably disposed on the guide shaft 12, a connecting plate 15 is installed on the slider 14, and a push rod is disposed at the rear side of the connecting plate 15. The first chuck 17 can be adjusted synchronously with the connecting plate 15 to be adjusted according to the shape and size of the workpiece. When fixing the workpiece, the pressure rod 19 pushes the chuck body 172 of the first chuck 17 towards the second chuck 26, and further clamps the workpiece between the chuck body 172 of the first chuck 17 and the second chuck 26, with good flexibility and strong practicability.

[0032] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0033] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
