Device for polishing rear angle of combined drill bit cutter

Abstract

The utility model relates to a combined drill tool orthogonal clearance coping device, in particular to a tool orthogonal clearance coping device and belongs to the field of coping. The combined drill tool orthogonal clearance coping device comprises a motor and a shaft, wherein the shaft is fixedly installed on an engine base through a bearing, one end of the shaft is provided with an elastic clamping sleeve and a fastening nut, the other end of the shaft is fixedly provided with a dividing plate, the dividing plate is provided with a dividing hole, the engine base is provided with a pin positioning hole enabling a pin to be inserted, and the output shaft of the motor is provided with a grinding wheel. The combined drill tool orthogonal clearance coping device is provided with a tracked horizontal moving function and a directional vertical push-and-pull coping manual function, can realize the coping of a tool moving along the X, Y, Z axes, enables the gear grinding dividing function and the clamping tool to be serialized, and is suitable for combined drill tool orthogonal clearance coping different in diameters. The clamping sleeve is convenient to exchange, and the problems that the manual coping is low in passing percent and reusing rate, and general equipment is low in coping efficiency and high in cost are solved.

Description

technical field [0001] The invention relates to a grinding device for cutter relief angle of a combined drill bit, in particular to a grinding device for grinding cutter relief angle, and belongs to the field of grinding. Background technique [0002] There are usually two methods for grinding the back angle after tool wear, one is manual grinding, and the grinding is performed by artificially controlling the angle; the other is grinding on a general tool grinder. [0003] 1. Manual grinding, artificially controlled angle grinding, the control is difficult, the back angle of each tooth is poor in consistency, the deviation is large, and even the grinding is scrapped, which affects the processing quality of the reused parts. The grinding efficiency is low and the qualified rate is low, which cannot meet the requirements of mass use of cutting tools. [0004] 2. Grinding on a general-purpose tool grinder, clamping and alignment operations are cumbersome. Since the height from...
