Description

Technical Field

[0001] The present application relates to the technical field of processing equipment, and in particular to a bushing processing tool for a shock absorber. Background Art

[0002] Shock absorbers are used to suppress the vibration caused by the rebound of the spring after absorbing shock and the impact from the road surface; they are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car; when passing over uneven roads, although the shock-absorbing spring can filter out the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] The shock absorber has a bushing inside. Due to structural requirements, connecting holes are respectively opened at both ends of the bushing. The central axes of the connecting holes on both sides are vertically arranged. When processing the bushing, the connecting holes at both ends of the bushing are punched out by a stamping die. Usually, the two ends of the bushing need to be stamped twice. Both stamping processes are performed by the operating techniques of the staff. Due to the position requirements of the connecting holes at both ends of the bushing, the qualified rate of the produced bushings is low. Utility Model Content

[0026] Reference Figure 2 and Figure 3A mounting seat 11 is horizontally placed at the upper end of the lower mounting plate 2, and the mounting seat 11 is located on one side of the pressing assembly 4. A first processing tube 12 and a second processing tube 13 are welded and fixed to one side of the mounting seat 11 close to the pressing assembly 4. The first processing tube 12 and the second processing tube 13 are horizontally arranged, and the first processing tube 12 and the second processing tube 13 are respectively located in the two second semicircular grooves 10. The two first semicircular grooves 7 correspond to the two second semicircular grooves 10. A first processing hole 14 connected up and down is opened on the side wall of the first processing tube 12, and a second processing hole 15 connected up and down is opened on the side wall of the second processing tube 13. A positioning groove 16 is opened at one end of the second processing tube 13 away from the mounting seat 11.
