[0030] Specifically, the fixed plate 13 plays a fixing role on the second telescopic motor 15, the fixed plate 13 plays a fixing role on the slide rail 19, the sliding bar 18 plays a fixing role on the first fixed block 17, the second telescopic rod 16 plays a pushing role on the first fixed block 17, the slide rail 19 plays a limiting role on the sliding bar 18, and the inclined slider 28 plays a lifting role on the rotating wheel 33. When the inclined slider 28 moves and the rotating wheel 33 rotates on the outer wall of the inclined slider 28, the inclined surface of the outer wall of the inclined slider 28 will be used to lift the rotating wheel 33, thereby lifting the lifting positioning plate 1, starting the second telescopic motor 15 fixedly connected to the upper surface of the fixed plate 13, starting the second telescopic motor 15 to prompt the second telescopic rod 16 to contract and pull the first fixed block 17 to move, thereby prompting the first fixed block 17 to drive the sliding bar 18 to slide on the outer wall of the slide rail 19, and when the sliding bar 18 slides on the outer wall of the slide rail 19, it also drives the inclined slider 28 to move, so that in the process of the inclined slider 28 moving, it will prompt the rotating wheel When the lifting height of the lifting and positioning plate 1 needs to be adjusted, the inclined sliding block 28 can be replaced with the inclined sliding block 27 to drive the threaded rod 26 to rotate inside the first fixing column 22. When the orientation of the rotating block 27 is the same as the orientation of the first clamping groove 24 opened on the upper surface of the clamping plate 23, the rotating block 27 can pass through the inner wall of the first clamping groove 24. At this time, the clamping plate 23 is rotated on the outer wall of the first fixing column 22, so that the first clamping block 25 slides out along the outer wall of the second clamping groove 30 opened on the outer wall of the second clamping block 29. After sliding out completely, the inclined sliding block 28 can be taken out and then the inclined sliding block 28 with different inclination angles can be replaced, so as to adjust the lifting height of the lifting and positioning plate 1.

[0031] Working principle: when the mechanism needs to be used, it is only necessary to start the first telescopic motor 2 arranged on the upper surface of the lifting and positioning plate 1. The start of the first telescopic motor 2 causes the first telescopic rod 3 to contract, thereby causing the first telescopic rod 3 to drive the moving block 4 to move. In the process of the first telescopic rod 3 driving the moving block 4 to move, the moving block 4 drives the first connecting column 5 to move, thereby causing the connecting bar 6 to rotate on the outer wall of the first connecting column 5 while also rotating on the outer wall of the second connecting column 7 and causing the second connecting column 7 to pull the rectangular slider 8 to slide on the outer wall of the fixing bar 9. When the rectangular slider 8 slides on the outer wall of the fixing bar 9, it also drives the clamping plate 10 to move inward, fixing the workpiece to be fixed, thereby achieving the effect of clamping and fixing the workpiece to be lifted and lowered, and then it can To ensure that the workpiece remains stable during the lifting process and to prevent the workpiece from sliding or tilting during the lifting and positioning process, the second telescopic motor 15 fixedly connected to the upper surface of the fixed plate 13 is started. The second telescopic motor 15 is started to cause the second telescopic rod 16 to contract and pull the first fixed block 17 to move, thereby causing the first fixed block 17 to drive the sliding bar 18 to slide on the outer wall of the slide rail 19. While the sliding bar 18 slides on the outer wall of the slide rail 19, it also drives the inclined slider 28 to move. Therefore, during the movement of the inclined slider 28, the rotating wheel 33 is caused to rotate on the outer wall of the inclined slider 28 and the inclined surface on the inclined slider 28 is used to lift the second fixed column 32 and the vertical rod 31 upward, thereby lifting the lifting and positioning plate 1. The lifting of the lifting and positioning plate 1 will promote The slide column 11 is made to slide on the inner wall of the slide cylinder 12 fixedly connected to the upper surface of the fixed plate 13. When it is necessary to replace the inclined slide block 28 with different inclination degrees to adjust the lifting height of the lifting and positioning plate 1, it is only necessary to rotate the rotating block 27 to drive the threaded rod 26 to rotate inside the first fixed column 22. When the orientation of the rotating block 27 is rotated to the same as the orientation of the first clamping groove 24 opened on the upper surface of the clamping plate 23, the rotating block 27 can pass through the inner wall of the first clamping groove 24. At this time, the clamping plate 23 is rotated on the outer wall of the first fixed column 22, so that the first clamping block 25 slides out along the outer wall of the second clamping groove 30 opened on the outer wall of the second clamping block 29. After it slides out completely, the inclined slide block 28 can be taken out and then the inclined slide block 28 with different inclination angles can be replaced to achieve lifting and positioning. The lifting height of the plate 1 can be adjusted by replacing the inclined slider 28 with different inclination degrees to adjust the lifting height of the lifting and positioning plate 1, thereby optimizing the lifting speed and force, changing the lifting trajectory, improving the flexibility and adjustability of the system, and better meeting the needs of different applications. The device can not only clamp and fix the workpiece to be lifted, thereby ensuring that the workpiece remains stable during the lifting process and preventing the workpiece from sliding or tilting during the lifting and positioning process, but also can achieve the effect of replacing the inclined slider 28 with different inclination degrees to adjust the lifting height of the lifting and positioning plate 1, thereby optimizing the lifting speed and force, changing the lifting trajectory, improving the flexibility and adjustability of the system, and better meeting the needs of different applications.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
