Special sand blasting equipment for inner tube of electromobile

Abstract

The invention discloses special sand blasting equipment for an inner tube of an electromobile. The equipment comprises a body. A first inlet-outlet, a sand blasting cavity and a mounting cavity that communicate successively are formed in the body from left to right. Transfer openings communicating with the sand blasting cavity are coaxially formed in the front and back sides of the body, a blocking mechanism is arranged above the inlet-outlet of the body, a rotating ring is coaxially arranged in the sand blasting cavity, a sand blasting gun is fixedly mounted circumferentially on the front surface of the rotating ring, arc-shaped second bumps are symmetrically and fixedly connected up and down on the front surface of the rotating ring, second limiting grooves sliding connected to the second bumps are formed in the inner wall of the front side of the sand blasting cavity, and arc-shaped first bumps are fixedly connected to the upper end of the second rotating ring. The equipment has theadvantages that the equipment achieves automation of sand blasting, transferring, vibrating and clamping of the inner tube body and the sand blasting gun is not controlled manually, so that the equipment is good in sand blasting quality and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of electric vehicle inner tube production, in particular to a special sandblasting equipment for electric vehicle inner tube production. Background technique [0002] Sand blasting equipment is a process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, corundum, iron sand, Hainan sand) to the surface of the workpiece to be treated at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes. , due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, thus improving the fatigue resistance of the workpie...

AI Technical Summary

Problems solved by technology

[0003] At present, sandblasting equipment is also used in the production process of electric vehicle inner tubes. The existing sandblasting equipment needs to manually control the sandblasting gun to rotate around the outer side of the inner tube, or rotate after each section of the inner tube is blasted for a certain period of time to clean the unsandblasted part. Sandblasting, the sandblasting operation is gradually completed on the outer surface of the inner tube, the workload of the staff is relatively large, and there may be cases where the outer surface of the inner tube adheres to the spray material
