AI Technical Summary
The existing automotive tail plate production burr repair device can only polish one side of the tail plate, and cannot polish the upper and lower sides and the circumference at the same time, resulting in low processing efficiency.
A burr repair machine for automobile tail plate production is designed, adopting the structure of two slide rods and two polishing discs. The sliding rod moves the polishing discs to contact the top and bottom sides of the tail plate, and drive the polishing discs through the motor. The grinding wheel rotates at high speed to achieve simultaneous polishing of the upper and lower sides and the peripheral sides of the tail plate.
By simultaneously polishing the upper and lower sides and peripheral sides of the tail plate, the time required for a single operation is significantly reduced, processing efficiency is improved, and the diffusion of dust and debris is restricted through protective covers, keeping the working environment clean and hygienic.
