A processing machine for automobile swing arm and its use method

Abstract

The invention discloses a processing machine for a swing arm of an automobile and a use method thereof, comprising a bottom plate, a gear one and a grinding pipe fixedly connected together, a rack plate fixedly connected to the surface of the driven shaft, the rack plate and the gear One phase is meshed, and the surface of the grinding tube is fixedly connected with abrasive cloth. The present invention has the following advantages: the abrasive cloth revolves around the driving shaft as the center of the circle and the elastic restoring force of the spring keeps away from the direction of the driving shaft, so that the abrasive cloth revolving around the driving shaft as the center of the circle can always cling to the triangular-shaped through groove on the swing arm of the car wall and rectangular through groove groove wall, so as to adapt to the grinding and polishing of groove walls of various sizes and shapes; Second, through the revolution and rotation of the emery cloth, and the reciprocating movement, the emery cloth and the through groove on the car swing arm Rolling friction and rotational friction are generated between the groove walls, which further improves the friction efficiency between the abrasive cloth and the triangular and rectangular through groove walls on the swing arm of the car, further improving the efficiency of grinding and polishing .

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
