[0011] A guide block is also fixed on the bracket, and inclined surfaces are respectively arranged on both sides of the top of the guide block.

[0012] By adopting the above technical solution, by arranging a limit block, a guide groove is formed between the limit block and the stop block, and the guide groove can limit the angle of the swivel housing within a certain range. At the same time, in cooperation with the guide block, the swivel housing can be roughly placed on the fixture in advance, which is convenient for subsequent clamping and fixing.

[0020] The following further elaborates on this application in conjunction with the attached drawings. Figures 1-3 This application embodiment discloses a fixture for processing a transposon housing. Referring to

[0021] Figure [missing figure number], it includes a base 1. The base 1 has the function of angle adjustment. Specifically, the base 1 includes a top plate 11 and a bottom plate 12. The top plate 11 is universally arranged on the top of the bottom plate 12. Adjusting components are symmetrically arranged between the top plate 11 and the bottom plate 12. The adjusting components include a lifting cylinder 13 and a fixed-point block 14. Both ends of the lifting cylinder 13 are respectively hinged to the bottom plate 12 and the top plate 11. An inclined surface is provided at the top of the fixed-point block 14, and the bottom of the top plate 11 can be attached to the inclined surface. Figures 1-3 The base 1 has the function of angle adjustment, which can facilitate the machining of the end face of the flange seat on the upper side of the transposon housing. When machining it, only the lifting cylinder 13 on one side of the machining surface needs to be raised, and the lifting cylinder 13 on the other side needs to contract until the top plate 11 abuts against the corresponding fixed-point block 14. The fixed-point block 14 can achieve the function of mechanical point alignment, with accurate point alignment and high precision, which can ensure the machining accuracy.

[0022] An inner support clamping mechanism 2, an angle positioning mechanism 3, and three support rods 4 are arranged on the base 1. The three support rods 4 are vertically and dispersedly fixed on the base 1 in a triangular shape, and the height of the support rods 4 is set according to the transposon housing, which can achieve three-point support for the transposon housing.

[0023] The inner support clamping mechanism 2 is arranged between multiple support rods 4. The inner support clamping mechanism 2 includes a bracket 21, a driving unit 22, a lifting block 23, and three clamping modules. The bracket 21 is fixed on the base 1. The driving unit 22 is installed in the bracket 21. The driving unit 22 is a lifting cylinder. The lifting block 23 is arranged at the top of the bracket 21 and is driven to lift by the driving unit 22. The three clamping modules are evenly arranged in a ring on the circumference of the lifting block 23. The clamping module includes a base 24, a clamping arm 25, and a connecting rod 26. The base 24 is fixed on the bracket 21. One end of the connecting rod 26 is hinged to the base 24, and the clamping arm 25 is hinged to the connecting rod 26. One end of the clamping arm 25 is hinged to the lifting block 23.

[0024] The angle positioning mechanism 3 is arranged beside the inner support clamping mechanism 2. The angle positioning mechanism 3 includes a support table 31, a stop block 32, and a quick clamp 33. The support table 31 is fixed on the base 1. The stop block 32 is fixed on the top of the support table 31. The quick clamp 33 is fixed on the side of the support table 31 and is arranged corresponding to the stop block 32.

[0025] Referring to

[0026] Figure [missing figure number] Figure 2, a positioning block 5 is also fixed on the support table 31. A guiding groove is formed between the positioning block 5 and the stopping block 32. A guiding block 6 is also fixed on the bracket 21, and inclined surfaces are respectively arranged on both sides of the top of the guiding block 6.

[0027] By providing the positioning block 5, a guiding groove is formed between the positioning block 5 and the stopping block 32. This guiding groove can limit the angle of the turntable housing within a certain range. At the same time, in cooperation with the guiding block 6, the turntable housing can be roughly placed on the jig in advance, facilitating subsequent clamping and fixing.

[0028] The implementation principle of a jig for processing a turntable housing in an embodiment of the present application is as follows:

[0029] Refer to Figure 3 , during use, the staff aligns the ear blocks in the turntable housing with the guiding groove, and places the turntable housing with the mounting holes facing the inner support clamping mechanism 2 on the jig. The turntable housing stays stably on the three support rods 4 under the action of its own gravity. Thereafter, the staff pushes the ear block part of the turntable housing against the stopping block 32 by hand, and the driving unit 22 pushes the lifting block 23 to move upward. The lifting block 23 drives the clamping arms 25 to turn over, and the three clamping arms 25 tighten the turntable housing from the inside of the mounting holes of the turntable housing. Finally, the staff tightens the ear block of the turntable housing against the stopping block 32 through the quick clamp 33 to prevent the angle of the turntable housing from shifting during the processing.

[0030] When machining the flange seat on the upper side of the turntable housing, only the lifting cylinder 13 on one side of the machining surface needs to rise, and the lifting cylinder 13 on the other side needs to contract until the top plate 11 abuts against the corresponding fixed point block 14. The fixed point block 14 can achieve the function of mechanical point alignment, with accurate point alignment and high precision, which can ensure the machining accuracy.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
