Problems solved by technology

[0002] In the manufacturing process of railway freight cars, the coupler buffer device is a very critical part, and its performance is directly related to the safety of the vehicle during driving. Therefore, higher requirements are put forward for the assembly quality of the coupler buffer device. All bolts have tightening torque requirements, which must meet the corresponding regulations of the national standard, and those that do not meet the regulations are judged as unqualified products, which will bring difficulties to the manufacturer.
[0003] During production and manufacture, the fastening bolts need to be pre-tightened before the assembly of the coupler buffer device. However, due to the space limitation of the car body structure, manual operation is very inconvenient when assembling the fastening bolts, and the assembly quantity of each vehicle is large, so Assembly changes are required to meet production needs
