The invention provides a flexible polishing device based on air injection. The flexible polishing device comprises a spray gun (1), a spray gun clamp (2), an injection cabin (3), a particle pipeline (4), a compressed air pipeline (5), an X-direction and Y-direction mobile platform (6), a Z-direction lifting platform (7), a C-axis rotating driver (8), a clamp holder (9), a frame (10), a filter screen (11), an exhaust fan (12), a screen (13), a collector (14), an illuminating device (15) and a control device. The flexible polishing device based on air injection polishes a workpiece, and the spray height and the spray angle of each flexible polishing particle can be controlled by the Z-direction lifting platform and the C-axis rotating driver in real time; through movement of the workpiece on the X-direction and Y-direction mobile platform, the spray gun performs full-range scanning on the surface of the workpiece, and the flexible polishing device is used for polishing surfaces of workpieces in complex shapes; the flexible polishing particles are collected by the collector for recycling, so that the polishing efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of polishing technology, and relates to a flexible polishing device based on the principle of air injection. Background technique [0002] The polishing process has a wide range of application requirements. In order to meet the requirements of product diversification and complex shapes, in the 1950s, the United States proposed abrasive jet processing, that is, the abrasive powder was ejected at high speed through compressed air, and the impact damage of the abrasive was used to remove the surface material of the workpiece to achieve the purpose of polishing. . This method can polish the surface of complex shapes, but the direct impact of the abrasive on the workpiece will cause processing defects such as work hardening, shallow burial of the abrasive, and deep scratches. [0003] The invention patent application with the patent application number 201310705372.X discloses a jet polishing method based on com...
