Grinding wheel grinding device, machine tool and inner hole groove machining method

Abstract

The invention relates to a grinding wheel grinding device, a machine tool and an inner hole groove machining method. The grinding wheel grinding device comprises a grinding arm which is used for suspending in a to-be-machined hole in an axial direction, a grinding wheel is rotationally assembled on the overhanging end of the grinding arm, a transmission structure used for being in transmission connection with a corresponding power mechanism is arranged on the grinding wheel, and the grinding wheel is provided with an outer peripheral surface used for grinding the inner wall of the to-be-machined hole. According to the grinding wheel grinding device, power is transmitted to the grinding wheel through two transmission wheels, the grinding wheel is clamped between the two transmission wheels,synchronous rotation of the grinding wheel and the two transmission wheels is realized, so that the groove on the hole wall of the to-be-machined hole is machined, the machining efficiency is high, the machined groove has higher contour precision, and the technical requirements of the high-precision groove are met.

Description

technical field [0001] The invention relates to a grinding wheel grinding device, a machine tool and a processing method for inner hole grooves. Background technique [0002] In the existing mechanical processing, the processing of linear grooves on the inner hole wall usually includes broaching, slotting and wire cutting, etc. Broaching and slotting need to be equipped with special forming tools, and different tools are required for different shapes. For small batch processing, the cost of cutting tools is very high. For large batch processing, the processing accuracy will gradually decrease with the wear of the cutting tools. For hardened or small-batch workpiece internal control ratio linear groove processing, although wire cutting can be used, the accuracy of the groove contour processed by wire cutting is not too high, and the surface roughness is also average, and the accuracy requirements are getting higher and higher. High grooves, especially the grooves of the guid...
