Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a tool for repairing and processing a train brake piece. Background Art

[0002] Train brake pads play an important role in train braking. They slow down or stop the movement of the train by contacting with the wheels to generate friction. An effective braking system is essential to the safety and operation of the train. Brake pads are usually made of materials with good wear resistance to ensure that they maintain stable performance during long-term use. However, under long-term friction, train brake pads will produce wear, thermal cracks, cracks and corrosion, so they need to be repaired or replaced. When the friction material layer on some brake pads is excessively worn or cracked, they need to be disassembled and replaced, while some brake pads only need to be repaired.

[0003] Train brake pads are generally symmetrically arc-shaped to better adapt to the curve of the wheel. Usually, the train brake pad frame is a thinner metal sheet with many mounting holes on it for installing brake pads. Train brake pad repair generally targets friction materials and brake pad frames, and the main repair methods are grinding repair and welding repair. In order to adapt to the existing brake pad installation, disassembly and repair technology, traditional manual clamping and disassembly can easily cause damage to the brake pads, and the process of tightening the bolts is relatively complicated. The automated clamping equipment needs to be precisely positioned, and the adjustability of the repair and processing tooling is high, and there are certain requirements for safety and ease of use. Summary of the invention

[0004] In view of the problems raised in the background technology, the purpose of the utility model is to provide a train brake pad repair processing tool suitable for automated disassembly, which has the characteristics of simple structure, easy processing, low cost, strong applicability, etc., and can effectively improve the efficiency of repair.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A train brake pad repair tool, comprising a base, a sliding positioning piece and a positioning pressing block; wherein: the train brake pad is placed on a plane on the base, one end of the train brake pad is placed on a mounting groove of the base, and the other end is fixed by a positioning pin of the sliding positioning piece; the sliding positioning piece can be fixed in the sliding groove by bolts, nuts and washers; the mounting groove is provided with two positioning grooves, a threaded hole is provided in the positioning groove, and the upper end is connected to the positioning pressing block, and the positioning pressing block limits the vertical movement of the train brake pad;

[0007] The train brake pad repair processing tooling is suitable for conventional symmetrical train brake pads. The sliding positioning piece can adjust the position according to the train brake pad positioning hole, and finally the positioning block is used for complete positioning.

[0008] An inverted V-groove is provided on the upper surface of the bottom of the base, and the disassembled train brake piece can slide down to both ends from the groove.

[0009] Compared with the prior art, the utility model has the following improvements: the utility model has high adjustability and is suitable for automation systems; the positioning and clamping are simple, the manufacturing cost is low, and it is easy to use; the brake shoe frame installation can be adjusted forwards and backwards according to different repair methods; the steps of brake shoe repair are greatly simplified and the work efficiency is improved.
