Description

Technical Field

[0001] This utility model relates to the field of steering knuckle repair technology, specifically a simple tool for disassembling the kingpin of the steering knuckle. Background Technology

[0002] When repairing the steering knuckle (also known as the steering knuckle) of light trucks or agricultural machinery, it usually involves the disassembly of various pins. During the repair of the steering knuckle, the kingpin is difficult to disassemble due to its larger upper part and smaller lower part, coupled with inadequate lubrication.

[0003] When disassembling the kingpin and bushing of the steering knuckle, the traditional method is to knock the kingpin out with a hammer. However, hammering often damages the workpiece and may cause metal shavings to fly and injure people, thus affecting the disassembly effect. Therefore, we need to propose a simple tool for disassembling the kingpin. Utility Model Content

[0004] The purpose of this utility model is to provide a simple tool for disassembling the kingpin, avoiding damage to the workpiece caused by hammering, improving operational safety, effectively increasing the efficiency of kingpin disassembly, and having a simple structure, convenient use, and easy operation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple tool for disassembling the kingpin, comprising:

[0006] The base, and the support frame mounted on the base;

[0007] The jack installed in the middle of the upper surface of the base, and the circular top column set directly above the jack, enable quick disassembly of the steering knuckle kingpin;

[0008] The circular top column is fixedly connected to the top of the inner cavity of the support frame, and the axis of the circular top column and the axis of the jack rod are both set on the same axis.

[0009] Preferably, the support frame is U-shaped and welded to the upper surface of the base, and the jack is disposed in the inner cavity of the support frame.

[0010] Preferably, the base has a U-shaped cross-section, and the wall thickness of the base is the same as the wall thickness of the support frame.

[0011] Preferably, the outer diameter of the circular top column is larger than the outer diameter of the jack rod, and the lower surface of the circular top column is parallel to the upper surface of the jack rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model mainly utilizes the cooperation between the base, support frame, jack, and circular jack. The parallel surface formed between the jack and the circular jack facilitates the placement of the steering knuckle, thereby making it easier for the jack to push out the kingpin of the steering knuckle. This avoids damage to the steering knuckle caused by hammering, improves the efficiency and safety of kingpin disassembly, and enhances the maintenance efficiency of the steering knuckle. The overall structure is simple and practical. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1 This utility model provides a technical solution: a simple tool for disassembling the kingpin, comprising:

[0018] Base 1, and support frame 2 mounted on base 1;

[0019] The jack 3 installed in the middle of the upper surface of the base 1, and the circular top column 4 set directly above the jack 3, enable the quick disassembly of the steering knuckle kingpin.

[0020] The circular top column 4 is fixedly connected to the top of the inner cavity of the support frame 2, and the axis of the circular top column 4 and the axis of the top rod of the jack 3 are both set on the same axis.

[0021] The support frame 2 is U-shaped and is welded to the upper surface of the base 1. The jack 3 is installed inside the support frame 2. The shape of the support frame 2 facilitates the quick insertion of the steering knuckle. The corners of the support frame 2 can be reinforced with welded triangular plates to increase stress, thereby improving the service life of the support frame 2.

[0022] The base 1 has a U-shaped cross-section, and the wall thickness of the base 1 is the same as that of the support frame 2. The structure is simple and reduces production costs. At the same time, both the base 1 and the support frame 2 are made of welded steel plates, and the hollow design can reduce the overall weight of the device, making it easy to carry.

[0023] The outer diameter of the circular top post 4 is larger than the outer diameter of the top rod of the jack 3. The lower surface of the circular top post 4 is parallel to the upper surface of the top rod of the jack 3, which facilitates the placement of the steering knuckle between the circular top post 4 and the top rod of the jack 3, further improving the efficiency of disassembling the kingpin.

[0024] In use, first place the steering knuckle on the top of the push rod of jack 3, and ensure that the kingpin axis of the steering knuckle, the push rod axis of jack 3, and the axis of the circular push column 4 are all on the same straight line. This will control the push rod of jack 3 to push out the kingpin of the steering knuckle. When the diameter of the kingpin is smaller than the diameter of the push rod of jack 3, a circular block with a diameter smaller than the kingpin axis can be placed on the top of the push rod of jack 3. This will enable quick disassembly of the kingpin of the steering knuckle, avoid damage to the kingpin, and improve the reuse rate of the kingpin.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
