Description

A clamping component and a method for clamping assembly equipment thereof

technical field

The invention relates to the technical field of assembly of rail vehicle components, in particular to a clamping component and a method for clamping assembly equipment thereof.

Background technique

While the functionality of the vehicle is changing with each passing day, instruments and other equipment components are carried out in an assembly structure that is easy to assemble to improve the assembly efficiency of the vehicle. With the rapid development of my country's rail transit industry, in order to meet the needs of rapid assembly, and The convenience of overhaul and maintenance, and the requirements for assembly efficiency are getting higher and higher.

At present, the installation of equipment components is often carried out in the form of clamping. The operation is simple, and the disassembly and assembly of the equipment can be completed without using special tools. Among them, there are two schemes that stand out. One is the clamping scheme of elastic deformation of metal shrapnel, and the other The first is the barbed connection scheme, each with its own advantages and disadvantages.

Specifically, the clamping solution of the elastic deformation of the metal shrapnel generally needs to set up a base as the interface of the metal shrapnel, and the metal shrapnel is connected to the base. During the installation process, the metal shrapnel produces elastic deformation. After the stroke is completed, the metal shrapnel is no longer constrained by the installation hole, the shrapnel returns to its original shape, and generates a certain supporting force to realize the assembly of the placement parts and the installation hole. However, this clamping solution is limited by the deformation of the metal shrapnel, which provides limited stability, and requires high precision for parts matching. The interface base of the metal shrapnel generally requires precise mold opening to ensure accuracy. That is to say, the assembly precision is high and cannot be adapted to the installation environment of strong vibration.

The clamping solution using the barb structure is to match the equipment to be installed with the interface, and the clamping component uses the deformation of the "barb" structure to generate elastic force to realize the fastening of the equipment and the interface. This clamping solution is limited by the material of the "barb" structure, and the stability provided is limited, and there will be gaps in the tangential direction of the contact surface, and the device will vibrate slightly during operation, so it is not suitable for assembly with a large weight .

Therefore, there is a need for a new clamping component structure to meet the requirements of heavy weight and low precision installation in rail transit vehicles.
