AI Technical Summary
In the existing technology, the grinding efficiency of the helical mating surface of large-pitch rod-type helical mating parts is low, the mating accuracy is poor, and the surface quality is unstable. Traditional equipment cannot simulate the helical motion trajectory, and manual grinding is inefficient.
A workpiece grinding device was designed. By cooperating with a clamping component and a lifting component, the first and second workpieces rotate relative to each other to achieve grinding of the threaded surface. The clamping component rotates synchronously under the action of the abutting force of the second workpiece to reduce motion matching error. The lifting component stably controls the abutting force and, together with the blowing component, removes debris to achieve automated grinding.
It improves the fitting accuracy and surface quality stability of the spiral mating surfaces, significantly enhances grinding efficiency, meets the needs of mass production, and solves the problem of low efficiency in manual grinding.
