Description

Technical Field

[0001] This application relates to the technical field of shock absorber production, and particularly to a spring compression mechanism. Background Art

[0002] A shock absorber is used to suppress the oscillation when the spring rebounds after absorbing shock and the impact from the road surface. It is widely used in automobiles to accelerate the attenuation of the vibration of the vehicle frame and body, so as to improve the ride comfort of the vehicle. When passing through an uneven road surface, although the shock-absorbing spring can filter the road vibration, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring bounce.

[0003] Currently, a spring pressing device disclosed in a Chinese patent with the publication number CN219747867U includes a table board. A clamping member and a pressing member are installed at the upper end of the table board. The clamping member includes two fixed seats symmetrically fixed at the left side of the upper end of the table board. A bidirectional screw is rotatably connected between the two fixed seats. Two sliders are symmetrically threadedly connected to the outer ends of the bidirectional screw. A clamping block is installed at the right end of the slider. The inner end surface of the clamping block is recessed outward to form a V-shaped groove. The fixed part of a first driving device is installed at the rear end of the fixed seat located at the rear side. The movable part of the first driving device is connected to the rear end of the bidirectional screw. The pressing member includes two first telescopic devices with fixed parts respectively installed at the right ends of the two clamping blocks. A pressing plate is arranged at the movable part of the first telescopic device. The inner end surface of the pressing plate is recessed outward to form a semicircular groove. This structure achieves the purpose of mechanically pressing the spring onto the rod body of the shock absorber, facilitating the pressing operation of the spring and improving the working efficiency.

[0004] In actual use, it is found that the existing device clamps the piston cylinder through the clamping plates and simultaneously makes the two pressing plates clamp on the piston rod, resulting in the problem that the spring cannot be sleeved onto the piston rod for compression, and thus it is not convenient for the spring compression operation. Therefore, we propose a spring compression mechanism to solve the above problems. Summary of the Utility Model
