Description

Technical Field

[0001] The utility model relates to a simple composite bearing disassembly tool, which is used for disassembling composite bearings. Background Art

[0002] Composite bearings are an important component in modern mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Figure 1 As shown, the composite bearing 5 is usually installed in the shaft 7. After the composite bearing has been used for a period of time, it needs to be disassembled and replaced. However, since the composite bearing is a non-standard component, there is currently no special tool on the market that can disassemble it well. Therefore, it is particularly important to design and manufacture a tool specifically for disassembling the composite bearing. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a simple composite bearing disassembly tool. When in use, the composite bearing is fixed on the pin shaft of the utility model, and then the shaft connected to the composite bearing is hit downward with force, so that the composite bearing can be disassembled, thereby solving the problem that the composite bearing cannot be fixed and thus causing difficulty in disassembly.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a simple composite bearing disassembly tool, including a base, two support frames are arranged on both sides of the top surface of the base, a fixed block with a center hole in the center is fixed to the upper end of the support frame, and the center hole of the fixed block is a smooth hole, a pin shaft that can pass through the composite bearing hole is passed between the two fixed blocks, and the pin shaft and the center hole of the fixed block are clearance fit.

[0005] A further improvement of the technical solution of the utility model is that two stoppers are arranged on the base at front and rear positions between the two support frames.

[0006] A further improvement of the technical solution of the utility model is that: the base is an I-shaped steel.

[0007] A further improvement of the technical solution of the utility model is that the pin shaft and the support frame are steel bars.

[0008] A further improvement of the technical solution of the utility model is that: the fixing block is circular, square or hexagonal.

[0009] A further improvement of the technical solution of the utility model is that the support frame and the base are fixed by welding.

[0010] A further improvement of the technical solution of the utility model is that the fixing block and the support frame are fixed by welding.

[0011] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is:

[0012] When the utility model is used, the composite bearing to be disassembled is fixed on the pin shaft, and then the shaft connected to the composite bearing is hit downward with force, so that the composite bearing can be disassembled, the operation is simple, and time and labor are saved.

[0013] Two stoppers are arranged on the base of the utility model at front and rear positions between the two support frames, which play a certain limiting role when the composite bearing is disassembled, and can prevent the composite bearing and the shaft from swinging back and forth, making it easier to disassemble the composite bearing.

[0014] The new base of this experiment is I-shaped steel, which saves materials while ensuring the overall stability of the tool.

[0015] The utility model has a simple overall structure and is easy to manufacture; the steel bars used for the pin shaft and the support frame and the I-shaped steel used for the base are all common materials in production and life, and the manufacturing cost is low.

[0016] The support frame and the base, and the fixing block and the support frame are fixed by welding, so the structure is firm and the processing is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described in detail below in conjunction with the embodiments:

[0020] like Figure 1 As shown, a simple tool for disassembling composite bearings includes a fixing block 1, a pin shaft 2, a support frame 3, a base 4 and a baffle 6.

[0021] The base 4 is made of I-beam steel. This structure of the base 4 can ensure the overall stability of the tool, while also saving materials and reducing manufacturing costs. Two support frames 3 are arranged on both sides of the top surface of the base 4. A fixing block 1 is welded to the top of the support frame 3. The fixing block 1 can be a round, square or hexagonal nut with a center hole in the center, which is a light hole. There is a pin 2 in the two fixing holes that can pass through the hole of the composite bearing 5. The pin 2 and the center hole of the fixing block 1 are clearance fit. The overall structure is simple, with fewer parts, easy to manufacture and process, and a firm welding structure.

[0022] The material used for the base 1 is I-shaped steel, the material used for the pin 2 and the support frame 3 is steel bar, and the material used for the fixing block 1 is nut, which are commonly seen in production and life and have low manufacturing cost.

[0023] Two stoppers 6 are arranged on the base 4 at the front and rear positions between the two support frames 3, which play a certain limiting role when disassembling the composite bearing 5, and can prevent the composite bearing 5 and the shaft 7 from swinging back and forth, making it easier to disassemble the composite shaft bearing 5.

[0024] Method of use: When using the utility model, first insert the pin 2 into the hole of the composite bearing 5 to be disassembled, fix the combination of the composite bearing 5 and the shaft 7, and use relevant tools to hit the shaft 7 downward with force to achieve the detachment of the composite bearing 5 from the shaft 7.
