Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-4A machining fixture for a gearbox includes a mounting plate 1. A sliding frame 2 is symmetrically arranged on the upper surface of the mounting plate 1, on which multiple adjusting rods 6 are evenly arranged and slidably fitted. A second mounting frame 5 is vertically mounted on the middle of the side of one sliding frame 2 away from the other sliding frame 2 on the mounting plate 1. A first mounting frame 4 is symmetrically and vertically arranged on both sides of the second mounting frame 5. Both the first mounting frame 4 and the second mounting frame 5 are used to hold the adjusting rods 6. A first limiting mechanism 8 and a second limiting mechanism 9 are installed at the ends of the adjusting rods 6 away from the first mounting frame 4 and the second mounting frame 5, for holding the gearbox housing.

[0015] The mounting plate 1 has multiple mounting holes 11 for mounting the first mounting bracket 4 and the second mounting bracket 5. A collection tray 3 is horizontally placed on the upper surface of the mounting plate 1 between the two sliding brackets 2. The collection tray 3 has a collection cavity 31 for collecting liquid that falls during gearbox processing.

[0016] In addition, the sliding frame 2 has multiple sliding holes 21, and the adjusting rod 6 is slidably engaged in the sliding holes 21, which facilitates the linear sliding of the adjusting rod 6.

[0017] Meanwhile, the adjusting rod 6 includes a rod body including a sliding part 62 and a threaded part 61. The threaded part 61 is symmetrically screwed with a fixing component 7. The sliding part 62 has a screw hole 63 at one end of the rod body. The screw hole 63 is used for the installation of the first limiting mechanism 8 and the second limiting mechanism 9. The screw hole 63 facilitates the replacement of different first limiting mechanisms 8 and second limiting mechanisms 9.

[0018] The first mounting bracket 4 has multiple first through holes 41 evenly arranged vertically on its plate, and a first mounting foot 42 is provided at the bottom of the plate. The second mounting bracket 5 has multiple second through holes 51 evenly arranged vertically on its plate, and a second mounting foot 52 is provided at the bottom of the plate. Both the first through holes 41 and the second through holes 51 are larger than the diameter of the sliding part 62 rod. The first mounting foot 42 and the second mounting foot 52 are used to install at the mounting hole 11. The first through holes 41 and the second through holes 51 facilitate the passage of the adjusting rod 6.

[0019] Furthermore, the first limiting mechanism 8 includes a first limiting head 82, on which a screw 81 is provided for screwing into the screw hole 63. The second limiting mechanism 9 includes a second limiting head 91, which is screwed into the screw hole 63 in the same way as the first limiting mechanism 8. The first limiting head 82 and the second limiting head 91 are used to position the gearbox housing.

[0020] In this embodiment, when the gearbox cannot be laid flat due to simple processing such as coloring and assembly on the surface of the gearbox, this device can be used for positioning. By extending the adjusting rods 6 on both sides, the first limiting mechanism 8 and the second limiting mechanism 9 can be able to hold the uneven surface of the gearbox.

[0021] Furthermore, when adjusting the adjusting rod 6, loosen the fixing parts 7 that are tightened on both sides of the first mounting bracket 4 and the second mounting bracket 5, and then the sliding part 62 can slide at the sliding hole 21 to adjust the distance that the adjusting rod 6 extends on the sliding bracket 2. After the adjustment is completed, tighten the fixing parts 7 on both sides of the plates of the first mounting bracket 4 and the second mounting bracket 5.

[0022] Furthermore, based on the gearbox model, appropriate limit heads are selected. The second limit head 91 is used for support with a large contact area, and the first limit head 82 is used for support with a small contact area.

[0023] The collection tray 3 is placed between the two sliding frames 2, and the collection chamber 31 collects and recycles the processing waste liquid. Figure 2 To avoid polluting the environment.

[0024] In this invention, multiple adjustable rods 6 on the sliding frame 2, which can be adjusted laterally, work in conjunction with the first limiting mechanism 8 and the second limiting mechanism 9 to flexibly match the concave and convex surfaces of the gearbox. The sliding part 62 of the adjusting rod 6 moves freely within the sliding hole 21, and the threaded part 61 is locked by the fixing component 7. Figure 3 To achieve precise positioning, the first limiting head 82 and the second limiting head 91 are screwed into the screw hole 63 of the adjusting rod 6 via the screw 81. Figure 4 The appropriate limiting head can be selected according to the shape of the gearbox contact surface.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
