Hexagonal tip grinding process

Abstract

The invention discloses a hexagonal center grinding method. The hexagonal center grinding method is characterized by comprising the following steps: step a, an auxiliary shaft is selected and the central hole of the auxiliary shaft is a ground taper hole; the large-diameter section of the auxiliary shaft is of a regular hexagonal prism structure and the six surfaces of the hexagonal prism are taken as working faces; step b, one external surface of the large-diameter section of the auxiliary shaft is fitted and fixed with the upper surface of a sine disk, the lower end of the sine disk is directly supported on a base, and the middle of the sine disk is supported on the base by use of a block gauge; step c, the hexagonal center is mounted in the central hole of the auxiliary shaft, and the first small plane of the hexagonal center is ground by use of a grinding wheel; step d, after one small plane of the hexagonal center is ground, the auxiliary shaft is rotated to grind the rest small planes of the hexagonal center. As the large-diameter section of the auxiliary shaft adopted in the hexagonal center grinding method is of the regular hexagonal prism structure, the six small planes of the hexagonal center are well kept equal in size and uniform in inclination angle in the peripheral direction; besides, the auxiliary shaft is designed into a three-section structure so that the machining area can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of hexagonal tip processing, and in particular relates to a hexagonal tip grinding process. Background technique [0002] The hexagonal tip is a commonly used tip shaft. The shaft body of the tip has a Morse taper, and the large end of the tip has six facets uniformly distributed along the circumference. The six facets are equal in size and have the same inclination angle. Six facets are connected in turn to form six corners. At present, the six facets are generally divided by the dividing head first, and then the six facets are ground by the grinding wheel. After grinding, the six facets often have different sizes, uneven distribution, or differences in inclination angles, which leads to Cannot reach machining accuracy requirement, need to solve above-mentioned technical problem urgently for this reason. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a...
