Problems solved by technology
However, these two installation methods have certain limitations: the C-type tooling is bulky and inflexible in operation, and it takes time and effort to compress the spring, and the efficiency is low, so it is only suitable for small batch installation; although the cylinder compression device is time-saving and labor-saving, it is more efficient. , but it needs continuous supply of compressed air and special installation platform and installation frame, which takes up a lot of resources and high cost, and is suitable for mass installation

Embodiment Construction
[0012] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.
[0013] figure 1 Shown is the structural representation of the present invention.
[0014] The shock absorber mentioned in the present invention includes a shock absorber shell 2, a spring 3, a nut 1 and a bolt 4, the outer diameter of the head of the bolt 4 is slightly larger than the inner diameter of the spring 3, and the head of the bolt 4 is tapered of frustum.
[0015] The present invention specifically comprises the following steps,
[0016] 1) First put the spring 3 into the shock absorber shell 2, then insert the bolt 4 from the bottom of the spring 3 into the shock absorber shell 2, and then screw the nut 1 on the bolt 4 to compress the spring 3 until it reaches the predetermined value. The amount of compression, this method can be compressed without the use of bolsters;
[0017] 2) Place the pre-compressed spring 3 and shock absorber ...

The invention discloses a steering frame vibration absorber installation process. A vibration absorber comprises a vibration absorber shell, a spring, a nut and a bolt. The outer diameter of the head of the bolt is slightly larger than the inner diameter of the spring. Firstly the spring is installed in the vibration absorber shell, and the bolt penetrates out of the vibration absorber shell through the bottom of the spring, then the nut is screwed on the bolt to compress the spring till the pre-compression quantity is reached; the pre-compressed spring and the vibration absorber shell are placed in the corresponding installation position on a bolster; the bolster provided with the vibration absorber shell is arranged on a side frame, the nut is unscrewed, the bolt is removed and the spring is released, the installation position of the bolster and the side frame are adjusted, and the vibration absorber shell, the spring, the bolster and the side frame are installed. The steering frame vibration absorber installation process has the advantages of being small in occupied space, low in cost, flexible and maneuvering and high in efficiency and the installation process is suitable for mass production as well as small-scale production.
Description
technical field [0001] The invention relates to a shock absorber installation process and belongs to the technical field of railway wagons. Background technique [0002] The installation of the shock absorber of the railway freight car bogie usually adopts two forms: one is to place the shock absorber shell and spring in the bolster chute first, and then use C-shaped tooling to compress the shock absorber shell and spring to the predetermined Compression amount, then pass the positioning pin through the shock absorber shell and bolster to fix them, after the bolster, shock absorber shell, and spring are assembled on the same side frame, then pull out the positioning pin to complete the installation; the other is to put the The shock absorber shell and spring are placed in the bolster chute, and then the shock absorber shell and spring are compressed to a predetermined compression amount by the cylinder, and then the positioning pin is passed through the shock absorber shell ...
