Surface treatment device for end cover machining

Abstract

The invention discloses a surface treatment device for end cover machining. The surface treatment device comprises an electrostatic paint spraying gun body, wherein a switch pressing plate is rotationally arranged on the front surface of the electrostatic paint spraying gun body, a holding handle is fixed to one end of the lower surface of the electrostatic paint spraying gun body, a rotating groove is formed in the front surface of the switch pressing plate, a rotating column is arranged on the inner side of the rotating groove, a limiting hook is arranged on the front surface of the rotatingcolumn, a fixing column is arranged on the front surface of the holding handle, the limiting hook is connected with the holding handle in a matched mode through the fixing column, and an elastic clamping piece is fixed to the outer surface of the rotating column. By arranging the rotating groove, the rotating column, the elastic clamping piece, the limiting hook and the fixing column, inconvenience caused by pressing a switch pressing plate for a long time during spraying is avoided conveniently, the position of the switch pressing plate is adjusted and fixed conveniently, and the operation effect is improved; and by arranging a protective baffle and a connecting block, the situation that the paint is directly contacted with hands and corrodes the hands due to the fact that the paint drifts away towards the holding handle is avoided.

Description

technical field [0001] The invention belongs to the technical field of end cap processing, and in particular relates to a surface treatment device for end cap processing. Background technique [0002] End cover (Cover) is a back cover installed behind the motor and other casings, commonly known as "end cover". During the processing of the end cover, the surface is usually painted with an electrostatic spray gun to improve corrosion resistance. Effect, prolonging the service life of the end cap, the electrostatic spray gun is based on the principle of electrostatic spraying, by using the grounded object as the positive electrode, the paint atomization device as the negative electrode, and the paint atomization device with a high negative voltage, between the two electrodes It is made into an electrostatic field, so that the atomized paint particles are negatively charged, so that the paint is effectively adsorbed on the object to be coated on the opposite electrode.

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a surface treatment device for end cap processing to solve the problem that the existing surface treatment device for end cap processing proposed in the above background technology needs to press the electrostatic spray gun for a long time when spraying is required during use. Control the switch pressure plate, when there is no need to spray, the switch pressure plate resets under the action of the spring. When spraying for a long time, the operator needs to press the switch pressure plate for a long time, which will cause sore fingers and affect the use effect, which is not easy to use Adjust and fix the switch pressure plate. In addition, during the spraying process, the paint may drift to the holding hand, causing corrosion to the holding hand.
