Description

Technical Field

[0001] This utility model relates to the field of machine tool fixture technology, and in particular to a valve adjustment fixture for a steering screw, valve core and torsion bar assembly. Background Technology

[0002] The steering screw torsion bar assembly adjusting fixture is a tool specifically designed for the adjustment and assembly of automotive steering systems. Its main function is to precisely adjust the relative positions and fit between the steering screw, valve core, and torsion bar assembly to ensure that the steering system can work accurately and sensitively.

[0003] In practical use, existing steering screw torsion bar assembly regulating valve fixtures require the fixture and the threaded rod to be used together. Basically, one set of fixtures is needed for each model of screw, which increases the cost of fixture production. At the same time, the installation process of the fixtures involves tightening bolts one by one, which is very inefficient. Therefore, we propose a steering screw and valve core and torsion bar assembly regulating valve fixture. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a steering screw and valve core and torsion bar assembly adjustment valve fixture, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steering screw, valve core, and torsion bar assembly adjusting valve clamp, comprising a valve sleeve one, a valve sleeve two fitted on the outer wall of the valve sleeve one, a connecting plate mounted on one side of the valve sleeve one (specifically model B18), a spacer installed inside the valve sleeve two, an O-ring fixedly connected inside the valve sleeve one, a screw positioning sleeve mounted on the other side of the valve sleeve one, and a fastening assembly provided between the screw positioning sleeve and the valve sleeve one, the fastening assembly including a circular ring one fixedly connected to the screw. On one side of the outer wall of the positioning sleeve, an internal gear ring is rotatably connected to the outer wall of the first circular ring. A handle is fixedly connected to the outer wall of the internal gear ring. On the other side of the internal gear ring, a second circular ring is rotatably connected. Several protrusions are provided on the outer wall of the second circular ring. Several gears are rotatably connected to adjacent sides of the first and second circular rings. Each gear meshes with the internal gear ring. A screw is fixedly connected inside each gear. The screw is rotatably connected to the first circular ring. The outer wall of the valve sleeve has a threaded groove that matches the screw. The thread in the threaded groove is adapted to the screw.

[0006] The steering screw, valve core, and torsion bar assembly regulating clamp described in this utility model only requires removing the screw positioning sleeve when encountering different threaded rods. Replacing the screw positioning sleeve does not require replacing the entire clamp. The screw positioning sleeve and valve sleeve are connected by a fastening assembly. Rotating the internal gear ring causes the teeth of the internal gear ring to mesh with the outer walls of multiple gears. Driven by the internal gear ring, the screw in the middle of the multiple gears moves under the action of the threads. By driving multiple screws to move through one internal gear ring, the efficiency of the device during installation and disassembly is greatly improved.

[0007] A sleeve is fixedly connected to the middle of the first circular ring, and the other end of the sleeve is fixedly connected to the second circular ring.

[0008] The beneficial effects of this utility model are as follows: by designing the screw positioning sleeve to be detachable, when encountering different threaded rods, only the screw positioning sleeve needs to be removed and the screw positioning sleeve replaced, without replacing the entire fixture, thus reducing the number of fixtures produced and saving costs.

[0009] This invention uses a fastening assembly to allow for the simultaneous installation and removal of multiple screws, eliminating the need to tighten each screw individually, thus saving time and effort and improving the efficiency of component installation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1

[0017] Please see Figures 1 to 4 The steering screw, valve core, and torsion bar assembly control fixture includes a valve sleeve 2. A second valve sleeve 6 is fitted onto the outer wall of the first valve sleeve 2. A connecting disc 7 (model B18) is mounted on one side of the first valve sleeve 2. A spacer 1 is installed inside the connecting disc 7. An O-ring 3 is fixedly connected inside the first valve sleeve 2. A screw positioning sleeve 5 is mounted on the other side of the first valve sleeve 2. A fastening assembly 4 is provided between the screw positioning sleeve 5 and the first valve sleeve 2. The fastening assembly 4 includes a circular ring 401, which is fixedly connected to one side of the outer wall of the screw positioning sleeve 5. An internal gear ring 403 is rotatably connected to the outer wall of the circular ring 401. A handle 405 is fixedly connected to the outer wall of the internal gear ring 403. A circular ring 402 is rotatably connected to the other side of the internal gear ring 403. Several protrusions 408 are provided on the outer wall of the circular ring 402. Several gears 404 are rotatably connected to the adjacent side of the circular ring 401 and the circular ring 402. Each gear 404 meshes with the internal gear ring 403. A screw 406 is fixedly connected inside each gear 404. The screw 406 is rotatably connected to the circular ring 401. A threaded groove 407 is provided on the outer wall of the valve sleeve 2 to match the screw 406. The internal thread of the threaded groove 407 is adapted to the screw 406.

[0018] The steering screw, valve core, and torsion bar assembly regulating clamp described in this utility model only requires removing the screw positioning sleeve 5 when encountering different threaded rods. Replacing the screw positioning sleeve 5 does not require replacing the entire clamp. The screw positioning sleeve 5 and the valve sleeve 2 are connected by the fastening assembly 4. Rotating the internal gear ring 403 causes the tooth ends of the internal gear ring 403 to mesh with the outer walls of multiple gears 404. Driven by the internal gear ring 403, the screw 406 in the middle of the multiple gears 404 moves under the action of the thread. By driving multiple screws 406 through one internal gear ring 403, the efficiency of the device during installation and disassembly is greatly improved.

[0019] A sleeve is fixedly connected to the middle of the first circular ring 401, and the other end of the sleeve is fixedly connected to the second circular ring 402.

[0020] Working principle: When encountering different threaded rods, only the screw positioning sleeve 5 needs to be removed and replaced. There is no need to replace the entire fixture, reducing the production cost of the fixture. The screw positioning sleeve 5 and the valve sleeve 2 are connected by the fastening assembly 4. When the internal gear ring 403 is rotated, the tooth ends of the internal gear ring 403 mesh with the outer wall of multiple gears 404. Under the drive of the internal gear ring 403, the screw 406 in the middle of the multiple gears 404 moves under the action of the thread. By driving multiple screws 406 through one internal gear ring 403, the efficiency of the device during installation and disassembly is greatly improved.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
