Grinding tool for numerical control die shearing cutter edge

Abstract

A grinding tool for a numerical control die shearing cutter edge comprises a punch seat, a clamping jaw and a punch. An upper-down-through cutter handle hole and a left-right-through clamping jaw mounting hole are formed in the middle of the punch seat. The cutter handle hole is perpendicular to the clamping jaw mounting hole and communicates with the clamping jaw mounting hole. One end of the clamping jaw mounting hole is closed through a jacking plate. The clamping jaw is arranged in the clamping jaw mounting hole. The end, away from the jacking plate, of the clamping jaw extends out of the clamping jaw mounting hole, and the other end of the clamping jaw abuts against the jacking plate through springs; a clamping opening is formed in the middle of the clamping jaw, and a tapered clamping foot is arranged in the clamping opening; the punch is composed of a cutter and a calibration ring; the cutter is fixed to the axial middle portion of the calibration ring, a clamping groove is formed in a cutter handle of the cutter, the punch and the cutter handle hole of the punch seat are mounted in a matched manner through the cutter handle, and the tapered clamping foot and the clamping groove are mutually embedded in a matched manner so that fast fixed connection of the punch and the punch seat can be achieved; the clamping speed is increased, and the clamping difficulty is lowered; mounting is convenient and fast, and the precision is high; and fast reversing of the punch on the punch seat can be achieved; and the structure is simple, and the production difficulty and the manufacturing cost of the tool are lowered.

Description

technical field [0001] The invention belongs to the technical field of tool clamping devices, and in particular relates to a cutting edge grinding tool for a numerically controlled punching die. Background technique [0002] The shearing edge grinding tool is a tool that clamps the tool and can adjust a certain angle. The main structure of the shearing edge grinding tool on the market is: the three-legged jaw clamps the tool by tightening the locking screw. When When changing the tool, the tripod claw must be loosened or tightened with a special tool, which is labor-intensive and time-consuming, and the disassembly and installation efficiency is low, and the tool is often loosened due to the screw not being tightened, which affects normal work. Moreover, the angle adjustment of the above-mentioned shearing edge grinding tool is also relatively troublesome. It is realized by a combination of a rotating mechanism and an angle mark. Not only is the operation process very cumber...

Problems solved by technology

[0002] The shearing edge grinding tool is a tool that clamps the tool and can adjust a certain angle. The main structure of the shearing edge grinding tool on the market is: the three-legged jaw clamps the tool by tightening the locking screw. When When changing the tool, the tripod claws must be loosened or tightened with a special tool, which is labor-intensive and time-consuming, and the efficiency of disassembly and installation is low. In addition, the tool is often loosened due to the screw not being tightened, which affects normal work.

Moreover, the angle adjustment of the above-mentioned shearing edge grinding tool is also relatively troublesome. It is realized by a combination of a rotating mechanism and an angle mark. Not only is the operation process very cumbersome, but also the angle adjustment takes a long time. A certain position deviation will affect the service life

In addition, the price of this kind of cutting edge grinding tooling is generally high, which cannot meet the needs of consumers
