Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a fixture for quick disassembly of a tool wheel bearing housing. Background Technology

[0002] Cutting machines used in LCD panel and electronic panel cutting processes place stringent requirements on the cutter wheel bearing housing. These housings are used in critical cutting areas, and in practice, they often fail due to prolonged use, improper handling, or other reasons, necessitating replacement. However, this replacement process involves manual disassembly and reassembly of the bearing and shaft, which is inefficient, increases the risk of finger injuries, and can easily damage the bearing housing if the disassembly technique is flawed. Therefore, a cutter wheel bearing housing disassembly fixture is an indispensable tool for routine maintenance. Its main functions are to improve disassembly efficiency, reduce worker safety risks, and extend the lifespan of the bearing housing. While various fixtures are available on the market, most suffer from limitations in meeting specific usage requirements, susceptibility to damage, and poor compatibility.

[0003] Therefore, the need for a new type of fixture that can solve the above problems is particularly urgent and necessary. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a fixture that is simple in structure, easy to operate, and can improve the efficiency of disassembly and assembly. It can quickly disassemble the cutter wheel bearing seat, avoid injury to the operator, minimize the problem of damage to the cutter wheel bearing seat, and facilitate the operator to perform maintenance and replacement work.

[0005] This utility model is implemented as follows: a fixture for quick disassembly of a cutter wheel bearing seat includes a base, a support plate on both sides, and a sliding rod between the tops of the two support plates;

[0006] A fixing component includes two opposing fixing columns, each fixing column having an "L" shaped structure. The upper end of each fixing column is fitted onto the slide rod and locked onto the slide rod by bolts. Each of the two fixing columns has an arc-shaped groove on its opposing lower surfaces, and the arc-shaped grooves are opposite to each other. A support plate is located below the arc-shaped grooves.

[0007] An ejector assembly includes a handle and a screw. A top post is provided at the bottom of the screw. The handle is located above the screw. The lower part of the screw passes through the slide bar and is located between the two fixed posts.

[0008] Furthermore, both ends of the slide rod are bolted to the support plate.

[0009] The advantages of this utility model are as follows: By providing an arc-shaped groove on the opposite surface of the fixed column, it can be used to clamp the bearing; by providing a support plate, it can support the bearing and prevent it from falling off during disassembly; by providing a top column at the bottom of the screw, the top column pushes the shaft core out of the bearing during its downward movement. This utility model is a simple, easy-to-operate fixture that can quickly disassemble the cutter wheel bearing seat, improving disassembly and assembly efficiency. It avoids operator injury, minimizes damage to the cutter wheel bearing seat, and facilitates maintenance and replacement work for operators. Attached Figure Description

Detailed Implementation

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] like Figures 1 to 4 As shown, a jig 100 for quick disassembly of a cutter wheel bearing housing 200 includes a base 1, a fixing component 2, and an ejection component 3.

[0018] A support plate 11 is provided on both sides of the base 1, and a sliding rod 12 is provided between the tops of the two support plates 11. The two ends of the sliding rod 12 are locked to the support plate 11 by bolts.

[0019] The fixing assembly 2 includes two opposing fixing posts 21, each with an "L"-shaped structure. The upper end of each post is fitted onto the slide rod 12 and secured to the slide rod 12 with bolts 22. Loosening the bolts 22 allows the fixing posts 21 to slide on the slide rod 12, and tightening the bolts 22 secures the fixing posts 21 to the slide rod 12. Each of the lower ends of the two fixing posts 21 has an arc-shaped groove 211 on its opposing surfaces, and these grooves are positioned opposite each other. The two arc-shaped grooves 211 clamp the bearing 201. A support plate 212 is located below each arc-shaped groove 211. When the arc-shaped grooves 211 clamp the bearing 201, the support plate 212 supports the bottom of the bearing 201.

[0020] The ejector assembly 3 includes a handle 31 and a screw 32. A top post 321 is provided at the bottom of the screw 32. The handle 31 is located above the screw 32. The lower part of the screw 32 passes through the slide rod 12 and is located between the two fixed posts 21. By rotating the screw 32, the top post 321 can move up and down between the two arc-shaped grooves 211.

[0021] Working principle: First, loosen the bolts 22 on the fixing posts 21 to increase the distance between the two fixing posts 21. Then, place the bearing 201 of the cutter wheel bearing seat 200 in the arc-shaped groove 211. By moving the distance between the two fixing posts 21, the bearing 201 is locked between the two arc-shaped grooves 211, and the bottom of the bearing 201 is locked on the support plate 212. The shaft core 202 of the cutter wheel bearing seat 200 is aligned with the top post 321 at the bottom of the screw 32. Tighten the bolts 22 on the fixing posts 21 to fix the bearing 201. Finally, by rotating the handle 31, the screw 32 is moved downward, and the top post 321 is aligned with the shaft core 202 to push it out and fall off. It is simple and convenient.

[0022] This utility model features an arc-shaped groove 211 on the opposite surface of the fixing column 21, which can be used to clamp the bearing 201. A support plate 212 supports the bearing 201, preventing it from being pushed off during disassembly. A top post 321 at the bottom of the screw 32 pushes the shaft core 202 out of the bearing 201 as it moves downwards. This utility model is a simple, easy-to-operate fixture that improves disassembly and assembly efficiency, allowing for quick disassembly of the cutter wheel bearing seat. It avoids operator injury, minimizes damage to the cutter wheel bearing seat, and facilitates maintenance and replacement work.

[0023] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
