Abstract

The invention discloses an efficient grinding and chamfering device for shaft parts. The device comprises a main shaft, a feeding mechanism, a cone feeding mechanism, a grinding wheel and a dischargeplate; the main shaft is mounted in a main shaft box; the cone feeding mechanism comprises a cone arranged on the main shaft; multiple clamping grooves are formed in the outer peripheral surface of the cone; the cone cooperates with a discharge port of the feeding mechanism; the grinding wheel is arranged on a grinding wheel grinding mechanism; the grinding wheel cooperates with the cone for grinding shaft parts clamped in the clamping grooves; the axial direction of the grinding wheel is perpendicular to the axial direction of the cone; an adjustable half tile is arranged in a grinding area cooperated by the grinding wheel and the cone; and the discharge plate is arranged at a grinding back end of the cone. Automatic separation and continuous feeding of the cone are realized after batch placement of the parts; the cone continuously passes through the grinding area to realize continuous and efficient production; the problems of low efficiency and troublesome operation in a traditionalchamfering mode are solved; and meanwhile, the machining precision is high.

Description

technical field [0001] The invention relates to the technical field of chamfering and grinding of shaft parts, in particular to an efficient grinding and chamfering device for shaft parts. Background technique [0002] After the shaft parts are processed, burrs, sharp corners and other shapes will appear on the cross-section. These shape features are not only not conducive to the later assembly, but also easily damage the surface quality of other parts, scratch the skin of the operator, and cause production accidents. Therefore, the end face chamfering treatment of shaft parts is generally performed in the later stage of processing. In some machining workshops, the chamfering of shaft parts is usually done by lathe turning, milling machine chamfer milling, manual scraping and other methods. Cutting on lathes and milling machines can only be done on a single piece, and clamping is required before machining. The ratio of clamping time to cutting time is about 1:1, which is co...
