Description

Through-hole chamfering tool

Technical field

The utility model is related to lathe tooling fields, more particularly to through-hole chamfering tool.

Background technology

Chamfering refers to the corner angle of workpiece to cut into the processing on certain inclined-plane.Chamfering is to remove on part because machine adds The burr that work generates generally makes chamfering also for convenient for component assembly in part end.In traditional through-hole chamfer machining In, it is rotated using drilling machine band cutter, while cutter is abutted with the through-hole of workpiece, workpiece is pushed to be moved on work top, So that through-hole and cutter are coaxial.In this process, worker needs through a hand steered firmly workpiece, and another hand controls drilling machine driving Cutter moves down.When just starting to abut with workpiece due to cutter, through-hole is not coaxial with cutter, and the rigid of cutter is caused to start to cut The chamfering gone out is not coaxial with through-hole, has seriously affected the quality of chamfering.

Notification number is that the Chinese utility model patent of CN201442061U disclosed brake block steel back on April 28th, 2010 Facing attachment, the guide sleeve being located on cope plate are matched with the guide post being located in lower template；It is fixed with successively on the cope plate Backing plate, fixed plate and stripper plate are compressed with polyurethane stick between stripper plate and fixed plate；The upper end of pressure head passes through in fixed plate Centre bore after be packed on upper padding plate, the pressure head work lower end that when work is in the shape of the letter V can be stretched from the centre bore on stripper plate Go out；The radial through-hole that the chopping block being packed in lower template is equipped with axially extending bore and is communicated with above-mentioned axially extending bore, in above-mentioned axis Positioning pin, polyurethane plate and clamping plate are housed into through-hole, the tip of screw across above-mentioned radial through-hole is held out against on clamping plate. The upper end of positioning pin stretches out in the upper surface of chopping block, and can be matched with the location hole that workpiece is equipped with, to play positioning workpiece Effect.

But in the actual production process, different types of workpiece often has different size of location hole, meanwhile, it is mutually of the same race The workpiece of class is also resulted in location hole size and differed so that produced between location hole and positioning pin due to mismachining tolerance Raw gap, also can chamfer quality decline.Therefore there is a problem of that chamfer quality is poor.
