Abstract
The utility model provides a kind of residual centre drill remover, it is made up of a drilling rod, and the front end of drilling rod is provided with " U " shape groove, and the width of " U " shape groove notch is greater than centre drill bit diameter 0.2 ~ 0.5mm, drilling rod front end appearance arranges screw cutting, and the rear end of drilling rod is set to square grip shank.Its effect is: 1, can be taken out by the drill bit fractureed from forging easily; 2, avoid the situation generation that forging is scrapped, improve the economic benefit of enterprise.
Description
Technical field: the utility model relates to a kind of device removing residual process instrument from processing component, particularly a kind of residual centre drill remover.
Background technology: at machine industry, centre drill is a kind of cutter of general, the most the most frequently used machining center hole, and it is for the prefabricated accurate location of hole machined.Centre drill work in-process, often can occur that its head fractures in the phenomenon of forging inside, because centre drill is manufactured by carbide alloy Steel material, intensity is higher, broken drill is difficult in forging inside take out afterwards, and most cases causes forging to scrap, and makes the economy of enterprise impaired.
Summary of the invention: the purpose of this utility model is, for existing centre drill because in use its head fractures the recurrent situation of phenomenon causing forging to be scrapped in forging, and a kind of residual centre drill remover is proposed, the drill bit fractureed can take out by easily from forging, thus can solve centre drill preferably because of the problem causing forging to be scrapped in forging that fractures.
The purpose of this utility model can be realized by following technical proposals, a kind of residual centre drill remover, it is characterized in that, it is made up of a drilling rod, the front end of drilling rod is provided with " U " shape groove, the width of " U " shape groove notch is greater than centre drill bit diameter 0.2 ~ 0.5mm, and drilling rod front end appearance arranges screw cutting, and the rear end of drilling rod is set to square grip shank.
The degree of depth of " U " shape groove is 7 ~ 10mm.
Effect of the present utility model is: 1, can be taken out by the drill bit fractureed from forging easily, because the front end of this drilling rod is provided with " U " shape groove, its width is slightly larger than the diameter of centre drill drill bit, it is contained on upright drill by grip shank, " U " shape groove notch center is made just in time to aim at the bit central of the centre drill that fractures, the forging material of centre drill drill bit periphery can be removed by the screw cutting of drilling rod, then prizes drill bit gently, just it can be removed easily from forging; 2, avoid the situation generation that forging is scrapped, improve the economic benefit of enterprise.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is plan structure schematic diagram of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further elaborated:
Detailed description of the invention:
See accompanying drawing 1,2, a kind of residual centre drill remover, it is made up of a drilling rod, the front end of drilling rod is provided with " U " shape groove 1, the width of rebate of " U " shape groove 1 is greater than centre drill bit diameter 0.2 ~ 0.5mm, drilling rod front end appearance arranges screw cutting 2, and the rear end of drilling rod is set to square grip shank 3, and the degree of depth of " U " shape groove 1 is 7 ~ 10mm.
Work flow is: be installed on upright drill by grip shank 3 end of residual centre drill remover, the notch of " U " shape groove 1 is downward, the forging of centre drill drill bit is had to be fixed to below " U " shape groove 1 by disconnected, one end of the breaking of rod upwards, adjustment fixture, the notch center of " U " shape groove 1 is made just in time to aim at the bit central of the centre drill that fractures, open lathe, by lower handle, " U " shape groove 1 High Rotation Speed on one side of remover, run downwards on one side, the irony of forging around centre drill is just cut by the screw cutting 2 of " U " shape groove 1 to be got rid of, the centre drill drill bit fractureed just comes out, prize drill bit gently, drill bit is just removed easily.
