Description

Burr removing device for machining shock absorber guider Technical Field The invention relates to the technical field of deburring equipment, in particular to a deburring device for machining a shock absorber guider. Background The automobile shock absorber is generally arranged on an automobile suspension system, so that the vibration of an automobile body and an automobile frame can be quickly attenuated, and the running smoothness and the running comfort of an automobile are improved. The main function of the guide assembly in the shock absorber is to reduce the friction force between the piston rod and the guide bushing and improve the service life of the piston rod and the oil seal. The guide assembly consists of a guide part, a bushing, a sealing ring and a wave spring, wherein the sealing ring, the wave spring and the bushing are sequentially arranged at the inner diameter of the guide part, and a piston rod slides in the inner diameter of the bushing. The guide is generally produced by a powder metallurgy process, burrs exist at the joint of the dies due to the die forming process, and meanwhile, the guide is uneven in density distribution and easy to form burrs in the production process due to the fact that the guide presents multiple steps and large in height difference. The existence of burrs may cause assembly problems of the guide, and the residual burrs cause scratch problems of parts. Therefore, the deburring is required to be a high-end shock absorber part in the production process, the strength of the burrs after sintering is high and difficult to remove, and the deburring in the green stage improves the efficiency and reduces the cost. At present, a method for removing burrs of a green body by spraying a medium is commonly adopted, the medium can better contact with the inner surface and each corner of a guide part, and the method has a finer deburring effect, but the treatment effect of a larger plane is slower, the time required is longer, and the deburring efficiency is low.
