Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to a tooling for disassembling rubber springs. Background Technology

[0002] The main function of rubber springs in subway trains is shock absorption and cushioning, which helps reduce vibrations and noise generated when subway trains are running, making the journey more comfortable for passengers. At the same time, rubber springs also improve the stability and safety of the trains.

[0003] To ensure the safe operation of trains and the comfort of passengers, the rubber springs on subways today need to be disassembled and replaced after prolonged use due to aging, wear, loss of elasticity, or malfunction. However, there is currently no specific tooling to assist in the disassembly of rubber springs on subways, making manual disassembly difficult, labor-intensive, time-consuming, and inefficient. Therefore, there is an urgent need to provide a tooling for disassembling rubber springs on subways to assist in the disassembly of rubber springs, making the disassembly work simple and convenient.

Detailed Implementation

[0021] 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.

[0022] This utility model provides, for example Figure 1-4 The tooling shown includes a rubber spring disassembly tooling.

[0023] The rubber spring support seat 200 has a downwardly recessed positioning groove at its top for positioning the rubber spring. The positioning groove can fit into the bottom of the outer wall of the rubber spring, thereby enabling the rubber spring support seat 200 to support the rubber spring.

[0024] A mobile frame 100 is positioned below the rubber spring support seat 200 for transporting the disassembled rubber springs. The mobile frame 100 consists of a frame body and casters with wheel brakes mounted at the bottom of the frame body. It supports the rubber spring support seat 200 while simultaneously moving it, facilitating the movement of the rubber spring support seat 200 under the rubber springs in the subway and allowing the disassembled rubber springs to be easily removed from under the subway. A support spring 202 is provided between the mobile frame 100 and the rubber spring support seat 200 for cushioning and support. Utilizing the elastic deformation characteristics of the support spring 202, it can support the rubber spring support seat 200 while allowing the rubber springs to move freely from under the subway. After being disassembled from the subway, the weight of the rubber spring is cushioned, and the rubber spring and its support 200 can be adjusted downwards to change height, facilitating the removal of the entire fixture and the rubber spring from under the subway. In a preferred embodiment, a support slide rod 201 is fixedly connected to the bottom of the rubber spring support 200. The support spring 202 is movably sleeved on the outside of the support slide rod 201. A guide sleeve 203 is movably sleeved on the outer wall of the support slide rod 201. The cross-section of the support slide rod 201 is T-shaped. The bottom of the support slide rod 201 cooperates with the guide sleeve 203, which can guide the deformation direction of the spring 202, thereby keeping the support spring 202 deformed in the vertical direction, while maintaining the rubber spring support 202. The guide sleeve 203 remains stable during vertical lifting and lowering, improving the stability of disassembling and transporting the rubber spring. It is fixedly installed on the mobile frame 100. The bottom end of the support rod 201 extends below the guide sleeve 203 and is fixedly fitted with a limiting plate 205. The limiting plate 205 limits the bottom end of the support rod 201, preventing accidental detachment from the guide sleeve 203. A connecting bolt 206 is movably inserted into the bottom end of the limiting plate 205. The outer wall of the connecting bolt 206 is threaded into the bottom end of the guide sleeve 203. The connecting bolt 206 allows for detachment between the limiting plate 205 and the support rod 201, facilitating subsequent disassembly of the support rod 201. The top of the mobile frame 100 is fixedly connected... A support plate 204 is attached, and a guide sleeve 203 is fixedly connected to the support plate 204. The support plate 204 facilitates the bearing and positioning of the guide sleeve 203, enabling its fixed installation. Each of the four inner walls of the guide sleeve 203 has a straight groove 209, and each groove 209 contains a rotatable cylindrical roller 210. The outer wall of the cylindrical roller 210 extends to the outside of the straight groove 209 and fits against the outer wall of the support rod 201. Multiple cylindrical rollers 210 can be arranged vertically at intervals within the straight groove 209. The cylindrical rollers 210 fit against the outer wall of the support rod 201 and rotate during the up-and-down movement of the support rod 201, thus guiding the lifting and lowering process of the support rod 201.This also reduces frictional resistance and improves the smoothness of the lifting and lowering process of the support slide bar 201, thus making operation more effortless;

[0025] The pressing mechanism 300 is fixedly mounted on one side of the mobile frame 100. It drives the rubber spring support seat 200 downwards to compress the supporting spring 202. The pressing mechanism 300 can also drive the rubber spring support seat 200 vertically downwards, allowing it to be disassembled from the subway and further lowered. This ensures that when the mobile frame 100 transports the rubber spring support seat 202, the subway will not damage it. The rubber spring on the slide bar causes obstruction. The pressing mechanism 300 includes a fixed seat 301 fixedly mounted on the side wall of the movable frame 100. The top of the fixed seat 301 extends above the movable frame 100 and is rotatably connected to a hinge seat 302. A pressing rod 303 is fixedly connected to one end of the hinge seat 302 away from the fixed seat 301. The pressing rod 303 is a hollow frame shape. The rubber spring support seat 200 can move up and down inside the pressing rod 303, supporting both sides of the slide bar 201 and located on the pressing rod. A blocking shaft 207 is fixedly connected to the lower position of the pressing rod 303 to block the pressing rod 303. An auxiliary bearing 208 is fixedly sleeved on the outer wall of the blocking shaft 207. The auxiliary bearing 208 is located directly below the pressing rod 303, and the width of the auxiliary bearing 208 is greater than the thickness of the pressing rod 303. After applying downward pressing force to the pressing rod 303, the pressing rod 303 drives the hinge seat 302 to rotate around the hinge position with the fixed seat 301. During the downward movement of the pressing rod 303, it contacts the blocking shaft. The auxiliary bearing 208 on 207 moves the rubber spring support seat 200 downward by blocking, which compresses the support spring 202. The auxiliary bearing 208 can rotate after its outer ring contacts the outer wall of the pressing rod 303 and is squeezed, which reduces the frictional resistance between it and the pressing rod 303, making it easier and more convenient to press the pressing rod 303 downward. At the same time, the width of the auxiliary bearing 208 is greater than the thickness of the pressing rod 303 to ensure stable contact between the two.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
