A connecting shaft is provided at one end of the bidirectional screw rod 19, and a handle 20 is provided at one end of the connecting shaft. Connecting rods 21 are movably connected on both sides of the two fixed blocks 18, and a scissor-type support frame 22 is provided on the two connecting rods 21 on each side; both ends of the scissor-type support frame 22 are slidably fitted in the slide groove 5, and two connecting blocks 24 are provided on the lower side of the fixed plate 6, and the connecting blocks 24 are movably connected to the two ends of the scissor-type support frame 22; a linear groove 33 is opened on one side of the transparent protective frame 4, and the connecting frame 10 and the connecting shaft are slidably fitted in the linear groove 33 respectively, and a transparent protective door 34 is hinged on one side of the transparent protective frame 4.

[0019] like Figure 5-6As shown, the clamping mechanism of this embodiment includes a mounting plate 25 arranged on one side of the fixed plate 6, two elastic telescopic rods 26 are provided on one side of the mounting plate 25, a clamping plate 27 is provided at one end of the two elastic telescopic rods 26, and an anti-slip pad is provided on one side of the clamping plate 27; a bearing 28 is provided in the fixed plate 6, wherein one mounting plate 25 is connected to the bearing 28, and the other mounting plate 25 is connected to the rotating drum 8.

[0020] One side of the annular clamping plate 9 of this embodiment is provided with an elastic telescopic part, one end of which is connected to the rotating drum 8. The elastic telescopic part is an elastic telescopic rod, a spring, etc. in the prior art, and can be selected according to actual usage. Among them, when the traction rope 12 on one side of the annular clamping plate 9 releases the tension on the annular clamping plate 9, the annular clamping plate 9 can be reset under the elastic force of the elastic telescopic part itself, which is convenient for fixing the clamping plate 27 after the angle is adjusted, thereby improving the convenience of actual operation.

[0021] The cladding mechanism of this embodiment is a common cladding device in the prior art. An adjustable or conventional cladding device can be selected according to one's own needs. It can be used as a replacement for the cladding mechanism in this application without affecting the actual use of this device.

[0022] The application of one aspect of this embodiment is as follows: when in use, first place the workpiece to be processed on the workpiece placement table 31, and then rotate the handle 20. The handle 20 can drive the bidirectional screw rod 19 to rotate through the connecting shaft, so that the lifting platform 3 at one end of the two scissor-type support frames 22 can be driven to move under the relationship of threaded engagement, and in the process of movement, the two ends of the scissor-type support frames 22 will slide in the slide groove 5, and while sliding, the two fixed plates 6 can be driven to approach each other, thereby driving the two clamping plates 27 to clamp the workpiece. At this time, continue to rotate the handle 20 so that the clamping plates 27 continue to compress the elastic telescopic rod 26, which can make the clamping plates 27 more stable for the workpiece. When it moves to the moving height, stop moving, and then start the cladding mechanism to process the surface of the workpiece. When the processing is completed, pull the limit handle 11, and the limit handle 11 can drive the loop at one end of the traction rope 12. The annular clamping plate 9 moves and disengages from the circular clamping plate 7, thereby contacting the connection between the rotating drum 8 and the fixed plate 6. Then, the rotating drum 8 can be driven to rotate on the fixed plate 6 by rotating the connecting frame 10, and under the setting of the bearing 28, the two clamping plates 27 can be driven to rotate with the workpiece under the action of the extrusion force. When the workpiece rotates to the surface that has not been processed, the limit handle 11 is released. At this time, the annular clamping plate 9 will drive the annular clamping plate 9 and the circular clamping plate 7 to be re-clamped and fixed under the elastic force of the spring telescopic member, thereby completing the fixation of the workpiece after adjusting the angle, and then the cladding mechanism can be started again for processing. When the processing is completed, rotating the handle 20 in the opposite direction can reverse the above steps, which can drive the lifting platform 3 to reset, and during the resetting process, the clamping plate 27 will automatically release the clamping of the workpiece. Finally, the processed workpiece can be taken out by opening the transparent protective door 34.

[0023] Beneficial effect: through the provided rotating drum 8, the annular clamping plate 9 at one end of the traction rope 12 can be pulled by the limit handle 11 to move, and the annular clamping plate 9 can be controlled to be clamped with the circular clamping plate 7, so as to facilitate the control of the rotation of the workpiece on the clamping mechanism, and then the workpiece can be processed at multiple angles without manual re-fixation of the workpiece, which not only facilitates the operation of the staff, but also improves the processing efficiency of the workpiece, and under the setting of the transparent protective frame 4, the entire cladding device can be set inside it, which not only does not affect the operation of the staff, but also provides a guarantee for the personal safety of the staff, improves the safety of the cladding working environment, and under the setting of the lifting mechanism and the clamping mechanism, when adjusting the lifting platform 3, the clamping mechanism can be driven to automatically clamp the workpiece, so as to facilitate the subsequent processing of the workpiece, reduce the steps of manual operation, and further improve the efficiency of workpiece cladding; By means of the motor 15, the lifting platform 3 on the rotating seat 16 can be driven to rotate, thereby controlling the adjustment of the horizontal angle of the workpiece, facilitating the processing of different surfaces of the workpiece, and while the rotating seat 16 rotates, the guide slide 17 can be guided by the limiting position of the annular guide groove 13 to slide inside, thereby making the rotation of the rotating seat 16 more stable, and by means of the scissor-type support frame 22, both ends of the scissor-type support frame 22 can slide in the slide groove 5 when adjusting the height, so that the clamping plate 27 on the fixed plate 6 can be driven to clamp the workpiece, thereby facilitating the fixation of the workpiece before processing, making its operation more convenient and quick, and by means of the anti-slip pad, In order to increase the friction between the clamping plate 27 and the workpiece, the stability of the workpiece clamping can be further improved. Under the setting of the bearing, the other clamping plate 27 can reduce the friction generated during rotation when rotating with the workpiece, which is convenient for adjusting the angle of the workpiece. Through the transparent protective frame 34 and the straight groove 33, the limit handle 11 for adjusting the workpiece angle and the handle 20 for adjusting the workpiece position can be placed outside the transparent protective frame 34 without affecting the adjustment during workpiece processing. While improving the protection function, it does not affect the operation. With the setting of the transparent protective door 34, it is convenient for the staff to pick up the workpiece, which improves the convenience of the staff during operation.

[0024] It should be noted that all electrical devices involved in this application can be powered by batteries or external power supplies.
