Description

Technical Field

[0001] The utility model relates to the technical field of tool bar shock absorption, in particular to a tool bar shock absorber. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road. They are widely used in automobiles to accelerate the attenuation of the vibration of the frame and body to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping. If the shock absorber is too soft, the body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and hinder the normal operation of the spring. In the process of modifying the suspension system, hard shock absorbers must be matched with hard springs, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers, which are connected to the vibration-inducing crankshaft to counteract the torsional vibration of the crankshaft (that is, the crankshaft is affected by the cylinder The existing patent, patent announcement number CN204673297U, discloses a tool bar shock absorber, including: a main body, which is composed of a rod body and a tool head; a damper is arranged inside the rod body, the damper is columnar and has a water outlet channel at its center; the side surfaces of the left and right ends of the damper are respectively provided with several radial grooves, and each of the grooves is respectively provided with a shock-absorbing washer, each of the shock-absorbing washers abuts against the inner side of the rod body and each of the shock-absorbing washers is a hollow ring; the left and right bottom ends of the damper are respectively provided with a positioning washer, and the axial and radial directions of each positioning washer abut against the inside of the main body and each of the positioning washers is a hollow ring. The utility model uses several shock-absorbing washers to reduce the vibration force during mechanical processing, so as to minimize the phenomenon of tool vibration during mechanical processing.
