Description

Technical Field

[0001] The utility model belongs to the technical field of equipment for assembling a hydraulic shock absorber, and in particular relates to a tightening machine for assembling a hydraulic shock absorber. Background Art

[0002] Hydraulic shock absorbers are important vibration-damping components on the primary and secondary suspension devices of bogies (axles) of locomotives (diesel locomotives, electric locomotives), subway vehicles, urban light rail vehicles and large passenger vehicles on highways. They achieve the purpose of vibration reduction by forming hydraulic damping force through the reciprocating motion of the stretching and compressing piston rods. They have good vibration reduction and damping effects and flexible vibration reduction effects. They are key components for improving the stability, comfort and safety of high-speed operation of locomotives and vehicles. Hydraulic shock absorbers need to be assembled before use during production.

[0003] A tightening machine is an electric wrench tool. The application of servo tightening machines in the production and assembly process can reduce the labor intensity of employees.

[0004] The existing tightening machine for assembling hydraulic shock absorbers is not convenient for limiting and clamping the hydraulic shock absorbers during use. Usually, the hydraulic shock absorber components are directly placed on the operating table for processing. The hydraulic shock absorber is prone to position deviation during the tightening process. At the same time, the existing tightening machine is not convenient for disassembling and replacing the tightening head during use, which reduces the scope of application of the device. Therefore, we need to upgrade and transform it based on the existing technology. Utility Model Content
