Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1-5, A positioning mechanism for processing a plastic gear box body, including a bottom plate 1. On one side edge of the upper surface of the bottom plate 1, fixing seats 3 are symmetrically arranged. On one side of each fixing seat 3, a sliding seat 4 is movably arranged. On the upper surfaces of the fixing seat 3 and the sliding seat 4, positioning plates 5 are horizontally arranged. A plastic gear box body 2 is clamped between the two positioning plates 5, and the positioning plates 5 can play a positioning role.

[0021] Among them, one side wall of the plate body of the positioning plate 5 can be mutually attached to the side wall of the plastic gear box body 2. A first rubber pad 51 is arranged at the side wall of the positioning plate 5 that is attached to the plastic gear box body 2. A second rubber pad 52 is arranged on the upper surface of the positioning plate 5. A bolt 53 is arranged on the upper surface of the positioning plate 5. A second fixing component 6 is screwed on the bolt 53. The upper surface of the plate body of the positioning plate 5 is mutually attached to the bottom surface of the lower end of the side edge of the upper surface of the plastic gear box body 2. The positioning plate 5 can effectively clamp the plastic gear box body 2 and at the same time can also hold up its protruding side edge.

[0022] In addition, a rubber gasket 61 is arranged on the bottom surface of the second fixing component 6. The rubber gasket 61 is in contact with the upper surface of the plastic gear box body 2, and the rubber gasket 61 prevents the second fixing component 6 from leaving indentations on the plastic gear box body 2.

[0023] Moreover, a screw rod 31 is fixedly connected to one side wall of the fixing seat 3. A plurality of first fixing components 33 are screwed on the screw rod 31. On the surface of the side wall of the fixing seat 3 where the screw rod 31 is arranged and below the screw rod 31, a slide bar 32 is fixedly connected. The slide bar 32 is slidably provided with the sliding seat 4. The slide bar 32 facilitates the sliding of the sliding seat 4 back and forth, thereby adjusting the distance between the sliding seat 4 and the fixing seat 3.

[0024] At the same time, a slide hole 42 is horizontally and penetratingly opened on the body of the sliding seat 4. The slide bar 32 is arranged at the slide hole 42. The aperture of the slide hole 42 is the same as the diameter of the slide bar 32. A through hole 41 is horizontally opened above the slide hole 42. The screw rod 31 is arranged at the through hole 41. The aperture of the through hole 41 is larger than the major diameter of the screw rod 31. The through hole 41 facilitates the sliding seat 4 not to be restricted by the screw rod 31.

[0025] In addition, the first fixing components 33 are arranged on both sides of the sliding seat 4. After the first fixing components 33 on both sides of the sliding seat 4 are rotated on the screw rod 31, the position of the sliding seat 4 can be fixed.

[0026] In this embodiment, when it is necessary to work on the inside of the plastic gear housing 2, the plastic gear housing 2 can be clamped on this positioning mechanism. First, according to the size of the plastic gear housing 2, adjust the distance between the two sliding seats 4 and the fixed seat 3. Loosen the first fixing components 33 originally tightened on both sides of the sliding seat 4 so that the sliding seat 4 can slide freely on the slide bar 32. Then place the plastic gear housing 2 on the positioning plate 5, and then adjust the distance of the sliding seat 4 to ensure that the first rubber pads 51 of all the positioning plates 5 can fit against the side wall of the plastic gear housing 2, and the two positioning plates 5 on both sides can clamp the plastic gear housing 2 in the middle. At the same time, ensure that the bottom surface of the protruding side of the plastic gear housing 2 can also contact the second rubber pad 52. At this time, all the first fixing components 33 can be tightened to the side walls on both sides of the sliding seat 4, so that the sliding seat 4 cannot move.

[0027] After the sliding seat 4 is fixed, the plastic gear housing 2 cannot shake from side to side at this time. However, to prevent it from shaking up and down, at this time, screw each second fixing component 6 onto the bolt 53 and ensure that the side with the rubber gasket 61 faces down. After tightening the second fixing component 6, the installation of the plastic gear housing 2 is completed, and at this time, it can be processed.

[0028] In this utility model, by providing two pairs of fixed seats 3 and sliding seats 4 with adjustable distances, the clamping and positioning of plastic gear housings 2 with different widths are realized. And when the positioning plate 5 is clamped, while effectively clamping the plastic gear housing 2, it can also prevent it from generating clamping marks. This positioning mechanism can effectively clamp and position the plastic gear housing 2 to be processed, so that there is no need for manual support, and the plastic gear housing 2 will not shake during processing, improving the accuracy of processing.

[0029] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
