Description

Technical Field

[0001] This utility model relates to the field of recoil spring disassembly and assembly technology, specifically a recoil spring disassembly and assembly tool. Background Technology

[0002] A return spring (also known as a compound feed spring or return spring) is a common elastic element in mechanical engineering, primarily used to provide power, absorb impact forces, maintain motion balance, and store energy. Return springs are widely used in various equipment and machinery, such as hydraulic systems, power tools, and automotive suspension systems. The return spring is a core component of a hydraulic cylinder's return mechanism. Its main function is to store energy by compressing the return spring during operation, and then release this energy to push the component back to its original position, ensuring the component quickly enters its next working state. This is crucial for operational continuity and stability. The return spring is a key component that relies on elastic deformation to achieve component return. During assembly and disassembly, its preload must be overcome. Manual operation can easily lead to spring ejection, component damage, or personnel injury. Tooling can specifically address this problem. Tooling for assembling and disassembling return springs typically consists of specialized tools and equipment used for assembling and disassembling return springs, enabling efficient, safe, and precise operations. They are crucial in production lines, especially in high-frequency, high-volume production processes, significantly improving production efficiency and reducing the risks of manual operation.

[0003] The existing technology has the following problems: The existing recoil springs, due to their high energy storage state caused by compression during long-term use, require overcoming enormous elastic force during disassembly and assembly. This poses a safety hazard due to the risk of spring breakage during disassembly and assembly, and is also time-consuming, labor-intensive, and inefficient to perform manually. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tooling for disassembling and assembling recoil springs, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a recoil spring assembly and disassembly tooling, including a guide screw, a handle rod installed inside the guide screw, a body tube sleeved outside the guide screw, a plug one fixedly installed at one end of the body tube, a plug two fixedly installed at the other end of the body tube, and a bolt fixedly installed on the outside of the body tube.

[0006] As a preferred embodiment of this utility model, the screw portion of the guide screw is modified from an M20 bolt with a length of 106mm.

[0007] As a preferred embodiment of this utility model, the guide screw has a through hole inside, and the handle rod passes through the through hole into the guide screw.

[0008] As a preferred technical solution of this utility model, the plug is provided with an internal thread, and the screw part of the guide screw is rotatably connected to the plug.

[0009] As a preferred technical solution of this utility model, the second plug has a through hole in the middle, and both the second plug and the first plug are fixedly connected to the body tube by bolts.

[0010] Compared with the prior art, this utility model provides a tooling for disassembling and assembling a recoil spring, which has the following beneficial effects: This recoil spring assembly and disassembly tool uses a guide screw, a handle, a first plug, a body tube, a second plug, and bolts. First, the first and second plugs are fixed to both ends of the body tube using bolts. Then, the guide screw and recoil spring are inserted into the body tube through the first plug. After securing the body tube with a clamp, rotating the handle clockwise rotates the guide screw, gradually compressing the recoil spring. This allows for precise control of the compression. When the retaining ring at the front end of the guide rod inside the recoil spring protrudes from the second plug, a single person can quickly remove the retaining ring, completing the recoil spring assembly. Disassembly is performed, and after the recoil spring is repaired, this tool can also be used to install the recoil spring. It is easy to operate and use. This design avoids the risk of spring breakage, significantly improves work safety and maintenance quality, saves a lot of labor and time costs, improves production efficiency, and reduces repair time. By using an aluminum tube of appropriate size and a plug to limit the recoil spring, it is ensured that the spring body is stable and does not deviate during compression. At the same time, by designing and using a screw pressurization mechanism, the recoil spring is gradually compressed by rotating the guide screw, replacing manual pressing, and the compression amount can be precisely controlled.

[0013] 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.

[0014] Please see Figures 1 to 6 In this embodiment: a recoil spring disassembly and assembly tool includes a guide screw 1, a handle rod 2 installed inside the guide screw 1, a body tube 4 sleeved on the outside of the guide screw 1, a plug 3 fixedly installed at one end of the body tube 4, a plug 5 fixedly installed at the other end of the body tube 4, and a bolt 6 fixedly installed on the outside of the body tube 4.

[0015] In this embodiment, the screw part of the guide screw 1 is modified from an M20 bolt with a length of 106mm, which facilitates the processing and production of the guide screw 1 and can improve the processing and production efficiency. In this embodiment, the guide screw 1 has a through hole inside, and the handle rod 2 passes through the through hole into the guide screw 1, which facilitates the disassembly and assembly of the handle rod 2 and makes it convenient for work and use; In this embodiment, the plug 3 has an internal thread, and the screw part of the guide screw 1 is rotatably connected to the plug 3. By holding the handle 2, the guide screw 1 and the plug 3 can be easily rotatably connected. In this embodiment, the second plug 5 has a through hole in the middle. Both the second plug 5 and the first plug 3 are fixedly connected to the body tube 4 by bolts 6, which facilitates the fixed connection of the second plug 5 and the first plug 3 to the body tube 4 and improves the stability of the fixed installation.

[0016] The working principle and usage process of this utility model are as follows: When using it, the operator inserts the second plug 5 into one end of the body tube 4, and then fixes the second plug 5 to the body tube 4 by rotating the bolt 6. Then, the first plug 3 is inserted into the other end of the body tube 4, and the first plug 3 is fixed to the body tube 4 by rotating the bolt 6. Then, the guide screw 1 and the recoil spring, after being properly matched, are inserted into the body tube 4 through the first plug 3. After fixing the body tube 4 with a clamp, the handle rod 2 is rotated clockwise to drive the guide screw 1 to rotate. The screw part of the guide screw 1 gradually compresses the recoil spring, which can accurately control the amount of compression. When the retaining ring at the front end of the guide rod inside the recoil spring is exposed, a single person can quickly remove the retaining ring to complete the disassembly of the recoil spring. At the same time, after the recoil spring is repaired, this tool can also be used for the installation of the recoil spring. The operation is convenient.
