Machine for machining automobile swing arm and using method of machine

Abstract

The invention discloses a machine for machining an automobile swing arm and a using method of the machine. The machine comprises a bottom plate, a first gear is fixedly connected with a grinding pipe,a rack plate is further fixedly connected to the surface of a driven shaft, the rack plate is meshed with the first gear, and abrasive cloth is fixedly connected to the surface of the grinding pipe.The machine has the advantages that firstly, the abrasive cloth revolves with a driving shaft as the circle center, through elastic restoring force of a first spring in the direction away from the driving shaft, the abrasive cloth revolving with the driving shaft as the circle center can be always attached to a triangular through groove wall and a rectangular through groove wall on the automobileswing arm, and therefore, the abrasive cloth can adapt to grinding and polishing of groove walls in various sizes and various shapes; and secondly, the abrasive cloth revolves while rotating and reciprocates, so that rolling friction force and rotating friction force are generated between the abrasive cloth and the through groove wall on the automobile swing arm, the friction efficiency between the abrasive cloth and the triangular through groove wall and the rectangular through groove wall on the automobile swing arm is further improved, and the grinding and polishing efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of parts processing, in particular to a processing machine for an automobile swing arm and a method for using the same. Background technique [0002] The car swing arm is the guide and support of the suspension. Its deformation affects the wheel alignment and reduces the driving stability. The form and structure of the car swing arm are different. [0003] The current products still require specific size and shape abrasive cloths to adapt to the through grooves of different sizes and shapes of automobile swing arms, and then each time a different automobile swing arm is replaced for grinding and polishing, the corresponding abrasive cloth needs to be replaced. It is cumbersome to operate and has low practicability. In addition, when polishing, only the relative sliding process between the swing arm and the abrasive cloth is used to achieve the friction between the swing arm and the abrasive cloth. The fricti...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of processing machine and its using method for the swing arm of automobile, have one, through the elastic restoring force of emery cloth to revolve with the driving shaft as the center of circle and the spring always away from the direction of the driving shaft, make the driving shaft The abrasive cloth revolving around the center of the circle can always cling to the triangular and rectangular channel walls on the swing arm of the car, thus adapting to the grinding of groove walls of various sizes and shapes; While rotating and moving back and forth, rolling friction and rotational friction are generated between the abrasive cloth and the groove wall on the car swing arm, which further improves the moment between the abrasive cloth and the triangular groove wall on the car swing arm. The friction efficiency between the groove walls of the type through groove further improves the efficiency of grinding and polishing, and solves the problem that the prior art still needs a specific size and a specific shape of abrasive cloth to adapt to the through grooves of different sizes and different shapes of automobile swing arms, and then Every time a different car swing arm is replaced for grinding and polishing, the corresponding emery cloth needs to be replaced. process, to achieve the friction between the car swing arm and the emery cloth, the friction form is relatively simple, and only sliding friction is generated, which leads to the general problem of the grinding and polishing efficiency of the car swing arm through groove
