Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a disassembly device for the tapered ball joint of an automotive steering tie rod. Background Technology

[0002] Currently, the conical ball joint of the steering tie rod passes through the mounting cone hole on the steering rocker arm and is fixed with a lock nut. However, as the usage time increases, the fit between the conical ball joint and the mounting cone hole becomes increasingly tight. Due to structural limitations, the ball joint end face cannot be directly hammered with a copper hammer during disassembly. Instead, the ball joint can only be disassembled by hammering the outside of the rocker arm with a vibration method. However, this method has the following problems: high labor intensity, extremely low efficiency, easy damage to the rocker arm during disassembly, and safety risks during the hammering process. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a disassembly device for the tapered ball joint of automotive steering tie rods.

[0004] This utility model is achieved using the following technical solution:

[0005] A disassembly device for a conical ball joint of an automotive steering tie rod includes a left half-clamp, a right half-clamp, and a screw rod; both the left half-clamp and the right half-clamp are provided with multiple screw holes, which are arranged on the same axis and threadedly connected to the screw rod.

[0006] Furthermore, the inner middle part of both the left and right half-cards is a planar structure, and the bottom of both the left and right half-cards is a hook-shaped structure with an arc.

[0007] Furthermore, the top of the left half of the card is provided with a first protrusion, and the top of the right half of the card is provided with two second protrusions arranged vertically. The groove formed between the first protrusion and the two second protrusions is detachable, and both the first protrusion and the second protrusion are provided with screw holes.

[0008] Furthermore, the left half and the right half are made of tool steel.

[0009] Compared with the prior art, the present invention has the following beneficial technical effects:

[0010] This utility model, by setting up a left half-clamp, a right half-clamp, and a screw, allows for quick disassembly of the conical ball joint of the automotive steering tie rod, avoiding easy damage to the steering rocker arm during disassembly and reducing safety risks. The structure of this utility model is convenient to use and greatly improves disassembly efficiency. Attached Figure Description

[0012] In the diagram: 1. Left half of the card; 2. Right half of the card; 3. Screw; 4. First protrusion; 5. Second protrusion; 6. Planar structure; 7. Hook-shaped structure with an arc. Detailed Implementation

[0013] like Figure 1 The image shows a disassembly device for a conical ball joint of an automotive steering tie rod, comprising a left half-clamp 1, a right half-clamp 2, and a screw 3. Both the left half-clamp 1 and the right half-clamp 2 have multiple screw holes arranged on the same axis and threadedly connected to the screw 3. The screw 3 and screw holes preferably use coarse threads, and the end of the screw 3 is preferably a universal hexagonal thread, suitable for standard sockets, and can be operated using pneumatic or pneumatic tools.

[0014] Both the inner middle parts of the left half-clamp 1 and the right half-clamp 2 are flat structures 6, and the bottoms of both the left half-clamp 1 and the right half-clamp 2 are curved hook-shaped structures 7. The flat structures 6 on the inner sides of the left half-clamp 1 and the right half-clamp 2 are used to abut against the side of the conical ball joint of the steering tie rod, and the curved hook-shaped structures 7 at the bottom of the left half-clamp 1 and the right half-clamp 2 are used to abut against the connection between the conical ball joint of the steering tie rod and the steering rocker arm, which can prevent the left half-clamp 1 and the right half-clamp 2 from slipping due to an excessively small relative angle during the disassembly of the conical ball joint of the steering tie rod.

[0015] The left half of the card 1 has a first protrusion 4 on its top, and the right half of the card 2 has two second protrusions 5 arranged vertically on its top. The groove formed between the first protrusion 4 and the two second protrusions 5 is detachable. Both the first protrusion 4 and the second protrusion 5 are provided with screw holes. The relative positions of the left half of the card 1 and the right half of the card 2 can be adjusted within a certain range to adapt to the needs of working in confined spaces.

[0016] The left half (card 1) and the right half (card 2) are made of tool steel. They are formed by cutting a single piece of high-strength tool steel.

[0017] Working principle: When using, loosen the locking nut, unscrew the screw 3, adjust the relative positions of the left half-clamp 1 and the right half-clamp 2, and fit them onto the outside of the mounting cone on the steering rocker arm. The lower ends of the left half-clamp 1 and the right half-clamp 2 should abut against the connection between the steering tie rod cone ball head and the steering rocker arm. Screw in the screw 3 to initially fix the device on the ball head to be disassembled. Use a pneumatic / electric tool with a standard socket to screw in the screw 3 so that the screw 3 abuts against the top of the steering tie rod cone ball head, pushing the steering tie rod cone ball head out of the mounting cone hole of the steering rocker arm, thus completing the disassembly.
