The invention discloses a novel arc swinging plane
grinding device. The novel arc swinging plane
grinding device comprises a motor bracket, a motor I, a rigid
coupling, a lower arc-shaped guide rail,a cylindrical gear I, a cylindrical gear II, a bullseye eye wheel, a shaft I, a gear fixing frame, a lower swing arm, an upper swing arm, an upper arc-shaped guide rail, a fixed vertical plate, a motor plate, a bending shaft, a
bevel gear II, a motor II, a plum coupler, a shaft II, a cylindrical gear III, a cylindrical gear IV, a shaft III, a shaft IV, a
bevel gear I, a
universal joint, a fixed cross plate, a shaft V, a chuck, an inserting rod and a workpiece disc. The workpiece disc is driven by the mechanical mechanism and one motor to form an irrational number of autorotation, and at the same time, the other motor drives the workpiece disc to do swing movement with variable swing angle, so that the workpiece disc can realize the rotation and swing in the
grinding process, so that a grinding track line is not closed, and the distribution range of the track line in the grinding disc is enlarged. According to the novel arc swinging plane grinding device, and the precision and the efficiency of the plane grinding are improved.
