AI Technical Summary
Existing mechanical grinding equipment is difficult to clamp and change when processing alloy parts with complex shapes, resulting in low efficiency and serious dust pollution.
A burr removal device for alloy parts was designed. The device uses a drum filled with steel shot. The drum is rotated by a clamping spindle. The steel shot is flipped by a paddle to impact the workpiece surface and remove burrs. The steel shot is then dispersed by high-pressure air for all-round grinding. The workpiece surface position is adjusted by an encoder.
Eliminating the need for multiple clamping and positioning improves work efficiency, reduces labor and material costs, ensures grinding quality and environmental hygiene, and extends equipment life.
