Description

Technical Field

[0001] This utility model relates to a novel tooling for disassembling and assembling a spring compression mechanism. Background Technology

[0002] In rail vehicles, the return spring (also known as the reset spring) is an important component of the braking unit, mainly used to reset the internal structure of certain tread braking units. The return spring is fitted into the sleeve of the braking unit in a compressed state. During the maintenance of the tread braking unit of electric multiple unit (EMU) trains, the return spring needs to be disassembled, and after maintenance, it needs to be compressed and reinstalled. Currently, there are no convenient disassembly and reassembly tools available. Summary of the Invention

[0003] The problem to be solved by this utility model is to provide a new type of spring compression assembly and disassembly tooling, which overcomes the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a novel spring compression assembly and disassembly tool, including a clamp, a plug-in handle, and a disassembly handle;

[0005] The clamp includes two identical arc-shaped retaining rings, each arc-shaped retaining ring being part of a cylindrical structure. The cross-section of the arc-shaped retaining ring is arc-shaped, and both the upper and lower top surfaces of the arc-shaped retaining ring have limiting end plates. The side surfaces of the arc-shaped retaining ring have fixing insertion holes.

[0006] The plug-in handle has a U-shaped structure and has sliding holes that correspond one-to-one with the fixed plug holes. The outer side of the plug-in handle has plug-in units that correspond one-to-one with the sliding holes. The plug-in unit includes a rectangular plate fixed to the outer side of the plug-in handle. The rectangular plate has a countersunk hole coaxial with the sliding hole. A plug rod passes through the countersunk hole and through the sliding hole. The plug rod has an outer diameter larger than the inner diameter of the countersunk hole at one end located on the outer side of the plug-in handle. The middle part of the plug rod has a limiting ring plate. A spring is sleeved on the plug rod. The two ends of the spring abut against the limiting ring plate and the inner wall of the countersunk hole, respectively.

[0007] The disassembly handle has a U-shaped structure. The insertion handle can extend into the disassembly handle. Both ends of the disassembly handle have long openings, which correspond one-to-one with the ends of the insertion rods. The insertion rods can pass through the long openings. At this time, the ends of the insertion rods are located outside the disassembly handles, and the inner ends of the insertion rods retract into the sliding holes.

[0008] Optionally, the outer side of the disassembly handle has a guide slope at the long opening, with the two ends of the guide slope located at the end of the disassembly handle and the tail end of the long opening on the outer side of the disassembly handle, respectively. The edge of the guide slope at the end of the disassembly handle is connected to the inner side of the disassembly handle.

[0009] The advantages and positive effects of this utility model are as follows: Due to the adoption of the above technical solution, the steps during use are simple and easy to operate. Only an arc-shaped retaining ring is needed to hold the spring in place, followed by inserting two overlapping handles. Removing the handles then secures the spring. The spring can be quickly locked by inserting and removing the handles. Once locked, the spring will not tilt in its compressed state, and it will not pop out after being locked.

[0017] like Figures 1-5 As shown, this utility model provides a novel spring compression assembly and disassembly tool, including a clamp 1, a plug-in handle 2, and a disassembly handle 3;

[0018] The clamp 1 includes two identical arc-shaped retaining rings 1-1, which are part of a cylindrical structure (e.g., Figure 2 The cross-section of the arc-shaped retaining ring 1-1 is arc-shaped. The upper and lower top surfaces of the arc-shaped retaining ring 1-1 both have limiting end plates 1-1-1. The side of the arc-shaped retaining ring 1-1 has fixing insertion holes 1-1-2.

[0019] like Figure 3 As shown, the plug-in handle 2 has a U-shaped structure. The plug-in handle 2 has sliding holes 2-7 corresponding to the fixed insertion holes 1-1-2. The outer surface of the plug-in handle 2 has plug-in units 2-1 corresponding to the sliding holes 2-7. Figure 4 The insertion and removal unit 2-1 includes a rectangular plate fixed to the outer side of the insertion and removal handle 2. The rectangular plate has a countersunk hole 2-6 coaxial with the sliding hole 2-7. An insertion rod 2-2 passes through the countersunk hole 2-6 and the sliding hole 2-7. The end of the insertion rod 2-2 located outside the insertion and removal handle 2 has an insertion rod end 2-5 with an outer diameter larger than the inner diameter of the countersunk hole 2-6. The middle part of the insertion rod 2-2 has a limiting ring plate 2-3. A spring 2-4 is sleeved on the insertion rod 2-2. The two ends of the spring 2-4 abut against the inner wall of the limiting ring plate 2-3 and the countersunk hole 2-6, respectively. The insertion rod end 2-5 abuts against the outer side of the rectangular plate under the action of the spring 2-4.

[0020] The disassembly handle 3 has a U-shaped structure. The insertion handle 2 can be inserted into the disassembly handle 3. Both ends of the disassembly handle 3 have long openings 3-1, which correspond one-to-one with the insertion rod end 2-5. The insertion rod 2-2 can pass through the long opening 3-1. At this time, the insertion rod end 2-5 is located outside the disassembly handle 3, and the inner end of the insertion rod 2-2 retracts into the sliding hole 2-7.

[0021] The outer side of the disassembly handle 3 has a guide slope 3-2 located at the long opening 3-1. The two ends of the guide slope 3-2 are located at the end of the disassembly handle 3 and the tail end of the long opening 3-1 on the outer side of the disassembly handle 3, respectively. The edge of the guide slope 3-2 at the end of the disassembly handle 2 is connected to the inner side of the disassembly handle 3.

[0022] The process of installing the return spring 4 into the braking unit after the above structure has been repaired:

[0023] First, the restoring spring 4 is compressed using a press until its height is less than the height of the clamp 1. Then, two arc-shaped retaining rings 1-1 are used to wrap around the compressed restoring spring 4 from the side.

[0024] Then, the insertion handle 2 and the disassembly handle 3 are overlapped, so that the insertion handle 2 enters the disassembly handle 3. At this time, the long opening 3-1 passes between the insertion rod end 2-5 and the rectangular plate, the spring 2-4 on the insertion rod 2-2 is compressed, and one end of the insertion rod 2-2 enters the sliding hole 2-7 in the insertion handle 2.

[0025] The clamp 1, which encloses the restoring spring 4, is inserted into the overlapping insertion handle 2 and disassembly handle 3. At this time, the fixed insertion hole 1-1-2 on the arc-shaped retaining ring 1-1 is coaxial with the sliding hole 2-7 on the insertion handle 2. The disassembly handle 3 is pulled out backward to separate it from the insertion handle 2. At this time, the part of the long opening 3-1 on the disassembly handle 3 is disengaged from the insertion rod 2-2-. The insertion rod 2-2 is inserted into the fixed insertion hole 1-1-2 on the clamp 1 under the action of the spring 2-4, thereby fixing the clamp 1 and the restoring spring 4. At this time, the restoring spring 4 is restricted laterally by the arc-shaped retaining ring 1-1 on the clamp and longitudinally by the limiting end plate 1-1-1. Its whole body is locked by the clamp 1.

[0026] After the press is raised, the return spring 4 locked by the clamp 1 can be removed from the equipment. The return spring 4 in the clamp 1 is installed into the sleeve of the brake unit. When the clamp 1 and the return spring 4 are separated, the clamp 1 can be removed from the return spring 4 simply by inserting the long opening 3-1 on the disassembly handle 3 through the end 2-5 of the insertion rod and the rectangular plate.

[0027] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
