Shock absorber piston rod rolling groove tooling

Abstract

Disclosed is a damper piston rod snapping slot hobbing fixture. A bottom board is provided with a dovetail slot board through an adjusting base plate; the dovetail slot board is provided with a longitudinal adjusting dovetail which is compressed by a wedge-shaped pressing bar, and the longitudinal adjusting dovetail is provided with a fixture vertical board; a turning tool, a tool adjusting screw, a perforated dovetail strip and a support are mounted on the fixture vertical board; the turning tool and the fixture vertical board are compressed by a pressing block, and the perforated dovetail strip and the fixture vertical board are compressed by a pressing block; the perforated dovetail strip is provided with a support board, an adjustable U-shaped seat and a fine adjustment seat which are clamped on the perforated dovetail strip through a wedge-shaped pressing bar; an eccentric shaft is provided with a bearing and an isolation sleeve and mounted inside the hole of the adjustable U-shaped seat; a support is provided with an air cylinder through an air cylinder seat. The damper piston rod snapping slot hobbing fixture has the advantages of significantly improving the processing efficiency compared with existing turning modes, reducing the frequency of tool replacement and significantly improving the processing quality of workpieces.

Description

technical field [0001] The invention relates to a rolling groove tooling for a piston rod of an automobile shock absorber. Background technique [0002] At present, in the process of processing the groove of the piston rod of the automobile shock absorber, most of the grooves are processed by CNC lathe turning method. During the operation, the blades are frequently replaced, the production efficiency is low, the groove of the processed product has rough finish, and stress concentration is easy to occur, which greatly reduces the strength of the workpiece. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned existing problems and provide a high-efficiency automobile shock absorber piston rod rolling groove tooling. [0004] The present invention is realized through the following technical scheme: an adjustment backing plate is installed on the bottom plate, a dovetail groove plate is installed on the adjustment backing plat...
