Description

TECHNICAL FIELD

[0002] The shock absorber is a key component for reducing mechanical vibration, widely used in automobile industry, etc., and the automobile shock absorber usually works by hydraulic or gas principle, consuming vibration energy through fluid flow resistance or gas compression, and the shock absorber assembly includes outer cylinder, inner cylinder, piston and valve system, etc., wherein the piston is one of the core components of the shock absorber, which is located in the inner cylinder and controls the flow of oil inside the shock absorber through up and down movement, thereby generating damping force.

[0003] In the current process of finishing the drilling of the piston, the piston at the end of the previous processing process is grabbed by the up and down mechanism, placed in the drilling processing position and released, the piston is clamped and fixed again by the clamp on the processing position, and the drilling is started using a suitable drill bit, the appropriate rotation speed and feed speed are selected according to the size and depth of the hole, after the drilling is completed, the clamp releases the piston, and the up and down mechanism transfers the piston from the processing position to the discharging position; however, the hole on the piston is crucial for controlling the speed of the oil flowing through the piston, and any deviation may affect the working performance of the shock absorber, when the up and down mechanism transfers the piston, there are two actions of grabbing and releasing, and the clamp clamps the piston again after the up and down mechanism releases, the discontinuity of the operation will cause the position deviation of the piston on the processing position, and further cause the position deviation of the drilling; secondly, the clamp on the processing position clamps from the horizontal direction, which cannot play a good stabilizing role on the vibration generated in the vertical direction during processing; furthermore, when the drilling mechanism drills, the stability of the drill bit will be poor when the distance of the feed is lengthened, which is not conducive to improving the drilling precision.
