[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to FIGS. 1-5. The present utility model provides a technical solution: a special tool for precision turning the long end, including a base 1 and an axial pressing block 2. The axial pressing block 2 is arranged on the base 1. A radial sliding block 3 is slidably arranged on the axial pressing block 2. A pushing component for driving the radial sliding block 3 to move outwards is installed in the axial pressing block 2. A cover plate 4 is installed on the base 1. A bolt 5 is screwed on the cover plate 4, and the bolt 5 is rotatably connected to the pushing component. By turning the bolt 5, the pushing component is pushed to move, so that the radial sliding block 3 moves outwards and is inserted into the hole on the steering gear housing, and the axial pressing block 2 is pushed by the pushing component to make the radial sliding block 3 generate a pressing force on the hole of the steering gear housing.

[0018] One end of the base 1 has an outer shape matching the internal shape of the steering gear housing. The number of holes on the steering gear housing is four, and the number of the radial sliding blocks 3 corresponds to the number of the holes.

[0019] A limiting groove 6 is opened on the base 1. The axial pressing block 2 is located in the limiting groove 6, and the cover plate 4 limits the axial pressing block 2 in the limiting groove 6.

[0020] A placing groove is opened on the outer side wall of the axial pressing block. The radial sliding block is located in the placing groove.

[0021] An installation groove 7 is opened on the outer side wall of the axial pressing block 2. The pushing component is installed in the installation groove 7.

[0022] The pushing component includes a disc sliding block 8. The disc sliding block 8 is arranged in the installation groove 7. The bolt 5 is rotatably connected to the disc sliding block 8. Uniformly distributed T-shaped sliders 9 are slidably arranged inside the disc sliding block 8. The radial sliding block 3 is connected to the T-shaped slider 9 through a connecting rod.

[0023] Uniformly distributed inclined sliding grooves 10 are opened on the outer side wall of the disc sliding block 8. The T-shaped slider 9 is slidably arranged in the inclined sliding groove 10.

[0024] Working principle: When the utility model is in use, the servo housing is sleeved on the base 1. At this time, the holes on the servo housing correspond to the radial sliding block 3. Then, the bolt 5 is screwed. Since the bolt 5 is screwed to the cover plate 4 and rotatably connected to the axial pressing block 2, the bolt 5 drives the disk sliding block 8 to move deeper into the installation groove 7. Due to the restriction of the radial sliding block 3 and the connecting rod on the T-shaped slider 9, when the disk sliding block 8 moves, the T-shaped slider 3 moves towards the outer end in the inclined sliding groove 10, pushing the T-shaped slider 9 towards the outer end, driving the radial sliding block 3 to extend outwards and insert into the corresponding hole until the bolt 5 drives the disk sliding block 8 to fit against the bottom of the installation groove 7. Continuing to screw the bolt 5, the bolt 5 drives the disk sliding block 8 and the axial pressing block 2 to move deeper into the limiting groove 6. The axial pressing block 2 drives the radial sliding block 3 to move. The radial sliding block 3 contacts the four-hole side wall of the servo housing to generate a pressing force, making the axial force on the servo housing uniform and not generating a radial pressure.

[0025] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
