Drilling bit grinder

Abstract

The invention discloses a drilling bit grinder. A drilling bit mounting hole I (107) in a main body of a cutting location seat (23) of a cutting edge grinding seat is opposite to a grinding wheel (3) after inclined; when a drilling bit (90) is inserted into the drilling bit mounting hole I (107) by a fixture set, a central axis of the drilling bit (90) is obliquely opposite to a cutting face I of the grinding wheel (3); the drilling bit (90) is sleeved with the fixture set; after rotating, a guide rail fixing frame I drives the drilling bit (90) to rotate through the cutting location seat (23); a supporting seat (48) of a chisel edge grinding seat is positioned in the middle of a guide rail fixing frame II and rotationally connected with the guide rail fixing frame II; a position adjustment device II is arranged at the bottom of the guide rail fixing frame II; and the position adjustment device II drives the drilling bit to upwarp or descend through a chisel edge locating seat (57). The grinder can be used for grinding a cutting edge and a chisel edge of the drilling bit without an experienced operator when the taper-shank drilling bit is ground, the precision of the ground drilling bit is high, and the diameter range of the grinding drilling bit is wide.

Description

technical field [0001] The invention relates to a drill grinding machine. Background technique [0002] The drill bit grinder is a kind of regrinding of the used drill bit with worn cutting edge, so that the drill bit can be repeatedly ground and used, which greatly prolongs the service life of the drill bit. Drills are usually divided into two types: straight shank drills and tapered shank drills. Currently, the existing drill grinders grind the cutting edge and chisel edge of the drill by fixing the front end of the straight shank drill and the tapered shank drill. For taper shank drills, when the front straight edge is short, it cannot be ground, and it is limited by the spring chuck. Larger taper shank drills are not easy to grind. For large diameter taper shank drills, the operator usually Grinding by hand on a grinder, the height of the grinding edge is different, or using a tool grinder for grinding, the operation is complicated, and the operator has high requirement...

Drills are usually divided into two types: straight shank drills and tapered shank drills. Currently, the existing drill grinders grind the cutting edge and chisel edge of the drill by fixing the front end of the straight shank drill and the tapered shank drill. For taper shank drills, when the front straight edge is short, it cannot be ground, and it is limited by the spring chuck. Larger taper shank drills are not easy to grind. For large diameter taper shank drills, the operator usually Grinding by hand on a grinder, the height of the grinding edge is different, or using a tool grinder for grinding, the operation is complicated, and the operator has high requirements. It is necessary to master certain professional knowledge and skills. proficiency related
