[0025] As Figures 1-4 Shown, the output of driving motor 8 is equipped with driving shaft 9, and the top of driving shaft 9 is equipped with driving gear 13 meshed with driven gear 15, when using, driving motor 8 drives driving gear 13 to rotate through driving shaft 9, so that driving gear 13 drives driven shaft 10 to rotate through driven gear 15, i. e. tray 11 can be driven to rotate, so that different positions of workpiece can be machined by processing equipment.

[0026] As Figures 1-3 Shown, the top of U-shaped frame 2 is provided with circular chute 5, and four groups of sliding blocks 18 are slidably installed in the inside of circular chute 5, the top of sliding block 18 is equipped with support block 6, and the end of support block 6 away from sliding block 18 is connected with carousel 7, when carousel 7 rotates, support block 6 can rotate with carousel 7, and support block 6 can support carousel 7, which is beneficial to make the rotation of carousel 7 more stable.

[0027] As Figures 1-3As shown, the outer side of the rotating shaft 17 is provided with a fixed ring 19, and the outer side of the fixed ring 19 is uniformly provided with a slot 20.

The output end of the first electric cylinder 3 penetrates through the U-shaped frame 2, and the output end of the first electric cylinder 3 is provided with an insertion block 4. When the specified tray 11 is rotated to the machining equipment position, the first electric cylinder 3 pushes the insertion block 4 to move, and the insertion block 4 can be inserted into the corresponding slot 20. The insertion block 4 limits the fixed ring 19, which can prevent the rotating disc 7 and the rotating shaft 17 from continuing to rotate during the machining process, and is beneficial to improve the stability of the device.

[0028] Working principle:

[0029] In use, the device is connected to the power supply, and then different specifications of workpieces can be placed on different trays 11. The worker can start the second electric cylinder 12 through the control panel 21 to make the second electric cylinder 12 push the clamping plate 14 to move, so that the clamping plate 14 is tightly attached to the outer side of the workpiece. The workpiece can be clamped by the clamping plate 14, and the workpiece can be fixed on the tray 11.

[0030] During machining, the worker can first start the first electric cylinder 3 through the control panel 21 to make the first electric cylinder 3 pull the insertion block 4 to move, so that the insertion block 4 can be taken out from the slot 20. The insertion block 4 can be removed from the insertion block 4, so that the fixed ring 19 can be rotated.

[0031] Then the worker can start the stepping motor 22 through the control panel 21. The stepping motor 22 drives the rotating disc 7 to rotate at a frequency of ninety degrees each time through the rotating shaft 17, so that different trays 11 can be rotated to the machining equipment position.

[0032] After adjusting, the worker first closes the stepping motor 22 through the control panel 21, and then starts the first electric cylinder 3 through the control panel 21. The first electric cylinder 3 pushes the insertion block 4 to move, so that the insertion block 4 can be inserted into the corresponding slot 20. The insertion block 4 limits the fixed ring 19, which can prevent the rotating disc 7 and the rotating shaft 17 from continuing to rotate during the machining process, and is beneficial to improve the stability of the device.

[0033] During machining, the worker can start the driving motor 8 through the control panel 21. The driving motor 8 drives the driving shaft 9 to rotate through the driving gear 13, so that the driving shaft 10 is driven to rotate through the driven gear 15, so that the tray 11 is driven to rotate, thereby facilitating the machining equipment to machine different positions of the workpiece.

[0034] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
