A novel
linear motion plane
grinding device comprises an inserting rod, a cardan joint, a
bevel gear II, a lead screw sliding table, a sliding table back plate, a
bevel gear I, a linear guide rail, ashaft II, a sliding block, a motor plate, a cylinder gear II, a cylinder gear I, a motor II, a motor I, a bend shaft, a fixing vertical plate, a shaft IV, a fixing transverse plate, a chuck, a workpiece disc, a
grinding disc, a coupler I, a shaft I, a bull eye wheel, a shaft III and a coupler II. Through a mechanical structure, one motor is used for driving the workpiece disc to achieve irrationalnumber self-rotation, meanwhile, the other motor drives the workpiece disc to do the variable range
linear motion, the workpiece disc achieves the self-rotation movement and the linear movement in the
grinding process, the grinding track line is not closed, and the distribution range of the track line on the grinding disc is enlarged. By means of the novel
linear motion plane grinding device, thegrinding precision and efficiency are improved.
