Problems solved by technology

After the initial molding of the electric vehicle body, due to the pre-order stamping and welding process and the oxidation of the subsequent material itself, the surface of the body will be uneven and have fine granular protrusions, so rough grinding is required before fine grinding. For smoothing, relatively rough sandpaper is needed at this time, and the technician needs to find and polish the surface with fine particles with the naked eye, which is time-consuming and easy to miss, which will affect the subsequent process production

Abstract

The invention relates to a marking device for electric vehicle body before grinding, which comprises a body, a spring and a retainer. The inner upper surface of the body corresponding to each of the liquid outlets is welded with the spring; the other end of each spring is welded with the baffle; the baffle and the The inner and lower surfaces of the main body are in close contact; the baffle covers the corresponding liquid outlet. Therefore, this device is injected with water-soluble colored paint, which has played a marking effect on the rough particle surface of the vehicle body, so that the polishing technician can initially and comprehensively find the rough surface of the particle and carry out preliminary grinding, which improves the efficiency.

Description

technical field [0001] The invention belongs to the field of production equipment of electric vehicles, and in particular relates to a marking device before polishing of an electric vehicle body. Background technique [0002] In the prior art, in order to strengthen the adhesion of the paint and the smoothness of the paint on the car body, the car body needs to be polished before painting. After the initial molding of the electric vehicle body, due to the pre-order stamping and welding process and the oxidation of the subsequent material itself, the surface of the body will be uneven and have fine granular protrusions, so rough grinding is required before fine grinding. For smoothing, relatively rough sandpaper is needed at this time, and the technician needs to find and polish the surface with fine particles raised with the naked eye, which is time-consuming and easy to miss, which will affect the subsequent process production. Contents of the invention [0003] In order...
