[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0044] Example 1

[0045] Please refer to Figure 1-8A placement rack for mechanical maintenance includes a base 1 and an installation box 11. A placement plate 12 is fixedly connected to the upper surface of the installation box 11. Two placement grooves 13 are provided on both sides of the upper surface of the placement plate 12. A slide groove 2 is provided on the upper surface of the placement plate 12. Two slide grooves 2 are symmetrically provided. A clamping piece for clamping a mechanical part is slidably connected to the inner surface of the slide groove 2. A disassembly piece is slidably connected to the outer surface of the clamping piece above the placement plate 12. Both the upper surface of the base 1 and the lower surface of the installation box 11 are provided with movable grooves 2 53. Eight movable grooves 2 53 are symmetrically provided. A lifting piece for adjusting the height of the mechanical part is slidably connected to the inner surface of the movable groove 2 53. The clamping member includes a clamping plate 21 and a sponge 22. The clamping plate 21 is slidably connected to the slide groove 2. The clamping plate 21 is located below the placement plate 12 and is rotatably connected to a connecting plate 23 at one end. A rotating shaft 25 is rotatably connected to one end of the connecting plate 23. The outer surface of the rotating shaft 25 is located on both sides of the connecting plate 23 and is rotatably connected to a connecting plate 24. The connecting plate 24 is rotatably connected to the clamping plate 21 through a connecting rod. A sliding groove 26 is provided on the lower surface of the placement plate 12 at one side of the slide groove 2. A connecting plate 3 27 is slidably connected to the inner surface of the sliding groove 26. The connecting plate 3 27 is fixedly connected to the rotating shaft 25. A sliding groove 28 is provided inside the placement plate 12 at the upper side of the sliding groove 26. A connecting block 29 is slidably connected to the inside of the sliding groove 28. The lower surface of the connecting block 29 is fixedly connected to one end of the upper surface of the connecting plate 3 27. The connecting block 29 is internally rotatably connected to a rotating rod 3, a torsion spring 32 is fixedly connected between the rotating rod 3 and the connecting block 29, both ends of the outer surface of the rotating rod 3 are fixedly connected to rotating blocks 31, the inner surface of the sliding groove 28 is located below the rotating block 31 and is fixedly connected to a toothed plate 33, and a rack matching the toothed plate 33 is provided on the lower surface of the rotating block 31.

[0046] Implementation process: when it is necessary to clamp the mechanical component, place the mechanical component at the center position of the upper surface of the placement plate 12, rotate the rotating block 31 counterclockwise to release the meshing relationship between the rotating block 31 and the tooth plate 33, and then pull the rotating block 31 forward to drive the connecting block 29 and the connecting plate three 27 fixedly connected to the connecting block 29 to move synchronously. Because the connecting plate one 23 and the connecting plate two 24 are rotatably connected to the rotating shaft 25 fixedly connected to the lower surfaces of the clamping plate 21 and the connecting plate three 27, the movement of the connecting plate three 27 drives the connecting plate one 23 and the connecting plate two 24 to rotate around the rotating shaft 25, while the two clamping plates 21 move synchronously to the center position of the placement plate 12, and the bottom side of the mechanical component is clamped by the sponge 22, and then the rotating block 31 is rotated clockwise to make the rotating block 31 mesh with the tooth plate 33. Because the hardness of the sponge 22 is relatively low, it can prevent damage to the mechanical component when clamping it. When it is necessary to release the clamping effect on the mechanical component, the reverse operation can be performed.

[0047] Implementation benefits: The sponge 22 is used to clamp the bottom side of the mechanical component to prevent damage to the mechanical component, which is beneficial to the maintenance of the mechanical component.

[0048] Example 2

[0049] The disassembly part includes a mounting plate 42, one side of which is fixedly connected to the sponge 22, and the other side of which is fixedly connected to a T-shaped slide plate 41. A T-shaped slot 4 is provided inside the clamping plate 21, and the T-shaped slide plate 41 is slidably arranged with the T-shaped slot 4. A movable slot 43 is provided inside the clamping plate 21 at one end of the T-shaped slot 4, and a fixed plate 44 is slidably connected to the inner surface of the movable slot 43. A mounting slot 45 is provided inside the fixed plate 44, and a slide bar 46 is slidably connected to the inner surface of the mounting slot 45. A spring 47 is fixedly connected between the slide bar 46 and the mounting slot 45, and one end of the slide bar 46 extends to the outer side of the clamping plate 21 and is fixedly connected to a clamp block 48. Two clamp slots 49 are provided on the outer surface of the clamping plate 21 at the outer side of the movable slot 43, and the clamp block 48 is slidably arranged with the clamp slot 49.

[0050] Implementation process: When the sponge 22 needs to be replaced, the block 48 is pulled outward to drive the slide bar 46 to move synchronously, so that the block 48 is disengaged from the inside of the slot 49 and the spring 47 is compressed. Then, the block 48 is pulled downward to drive the fixing plate 44 to move synchronously, so that the fixing plate 44 is disengaged from the surface of the T-shaped slide plate 41. At this time, the slide bar 46 drives the block 48 to be stuck into the inside of the slot 49 on the bottom side under the elastic force of the spring 47, and the installation plate 42 is pulled to drive the T-shaped slide plate 41 to slide out from the inside of the T-shaped slot 4, thereby releasing the fixing effect of the sponge 22, making it convenient to replace and use the sponge 22. When the sponge 22 needs to be installed, the reverse operation can be performed.

[0051] Implementation benefits: The cleaning and replacement of the sponge 22 is realized, which makes it convenient for the staff to install sponges 22 of different shapes on mechanical parts of different shapes.

[0052] Example 3

[0053] The lifting member includes a sliding mounting block 54, the inner side of the sliding mounting block 54 is rotatably connected to a rotating plate 1 55, the center position of the outer surface of the rotating plate 1 55 is rotatably connected to a rotating plate 2 56 through a connecting shaft, one end of the rotating plate 2 56 is rotatably connected to a fixed mounting block 57, and the fixed mounting block 57 is fixedly connected to the upper surface of the base 1. The sliding mounting block 54, the rotating plate 1 55, the rotating plate 2 56, and the fixed mounting block 57 are arranged in a symmetrical array along the center line of the base 1. One end of the upper surface of the base 1 is fixedly connected to a mounting plate 2 5, one side of the outer surface of the mounting plate 2 5 is fixedly connected to a cylinder 51, the output end of the cylinder 51 passes through the mounting plate 2 5 and is fixedly connected to a slide plate 52, and both ends of the slide plate 52 are fixedly connected to the sliding mounting block 54.

[0054] Implementation process: When it is necessary to raise the placement rack, the cylinder 51 starts working to drive the slide plate 52 to move in the direction of the mounting plate 2 5, and the movement of the slide plate 52 drives the sliding mounting block 54 to slide synchronously inside the movable groove 2 53. Because the sliding mounting block 54 is rotatably connected to the rotating plate 1 55, the rotating plate 1 55 is rotatably connected to the center position of the rotating plate 2 56, and the rotating plate 2 56 is rotatably connected to the fixed mounting block 57, under the action of the fixed mounting block 57 being fixedly connected to the upper surface of the base 1, the movement of the sliding mounting block 54 drives the rotating plate 1 55 and the rotating plate 2 56 to rotate around the connecting axis, and at the same time, the sliding mounting block 54 and the fixed mounting block 57 above move upward, thereby driving the installation box 11 and the placement plate 12 to move upward, so that the height is increased. When it is necessary to lower it, the reverse operation can be performed.

[0055] Implementation benefits: It realizes height adjustment, which is convenient for staff to carry out maintenance.
