Grinding fixture

Abstract

The invention belongs to the technical field of machining and particularly relates to a grinding fixture. The grinding fixture comprises a bearing plate, a pushing and pulling assembly, an abutting assembly, a rotation assembly and a controller, wherein one end of the bearing plate is provided with a grinding station used for grinding workpieces, a rotation station which can rotate the workpieces to be ground is arranged at the position close to the middle of the bearing plate, the pushing and pulling assembly is arranged on the bearing plate, can enable the workpieces to be ground to reciprocate between the grinding station and the rotation station and can enable the workpieces to be ground to horizontally and tightly abut against the grinding station, the abutting assembly can vertically abut the workpieces to be ground against the grinding station, the rotation assembly is arranged below the rotation station and can rotate the workpieces to be ground, and the controller is used for controlling the pushing and pulling assembly, the abutting assembly and the rotation assembly to orderly move. According to the grinding fixture, automation is achieved during the whole process, and workers are not required for repeatedly installing fixtures to position the same workpiece to be ground, so that labor intensity of workers is reduced, non-operational time of the device is reduced, and production efficiencies are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a grinding fixture. Background technique [0002] In actual production, it is often necessary to grind multiple characteristic surfaces distributed circumferentially on some small parts, such as Figure 11 As shown, the workpiece 200 to be ground is in a triangular shape, and it is necessary to grind three pointed planes 201 distributed along its circumference. The tip plane 201 distributed in the circumferential direction, after the completion, the worker takes off the part to be ground, rotates it at an angle, and then re-clamps and grinds another tip plane 201, and repeats this until the workpiece 200 is ground. All the tip planes 201 distributed in the circumferential direction have been ground. In this way, the degree of automation is low. Grinding a part requires workers to manually clamp multiple times. The labor intensity of the workers is high, ...
