Description

One kind is used for mine working drill bit and Axile connection structure

Technical field

The utility model is related to mechanical fitting technical fields, specially a kind of to be used for mine working drill bit and axis connection Structure.

Background technology

Drill bit be on solid material drilling go out through-hole or blind hole, and can be to the cutter of existing hole reaming.It is common Drill bit mainly have fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Drill bit is to fractured rock, shape in drilling engineering Into the rock crushing tool of pit shaft.The efficiency of breaking rock and service life of drill bit directly affect the service index and performance of drill bit.Axis connection Structure is the auxiliary accessories for drill bit and peripheral hardware drilling machine are attached, convenient for the development to underground excacation.

Fluted drill is most widely used hole process tool.Ranging from 0.25~80 millimeter of general diameter.Its groundwork Part and shank are formed.Working portion has two spiral grooves, is similar to fried dough twist, thus gains the name.It is led during in order to reduce drilling Friction between part and hole wall, fluted drill are gradually reduced diameter from apex point to shank direction in inverted cone shape.The spiral of fluted drill Angle mainly influences the size of anterior angle on cutting edge, sword valve intensity and chip removal performance, usually 25 °~32 °.Spiral groove can be used The methods of milling, grinding, hot rolling or hot extrusion, processes, and the front end of drill bit forms cutting tip after sharpening.The cutting portion of chit drill It is divided into spade, simple in structure, manufacture is at low cost, and cutting fluid is easily in entrance hole, but cut and chip removal poor-performing.The knot of chit drill Structure has two kinds of monoblock type and assembled.Depth drill typically refers to the cutter in hole of processing the ratio between the hole depth and aperture more than six.It is common Have drill gun, BTA depth drills, jet drilling, DF depth drills etc..Cylindrical drill is also commonly used for deep hole machining.Hollow boring bit is called coring Drill bit, magnetic force drill bit, magnetic support drill bit, hole making drill.After drill bit two-edged milled, it can be influenced at two-edged sharp point there are one plane The centralized positioning of drill bit, need behind sword fall an inferior horn, the plane in blade tip portion is ground as possible small.Method is to hold up drill bit, The angle of grinding wheel is directed at, a sulculus is fallen in the root behind sword against blade tip.This is also bit centering and cuts brisk weight It wants a bit.Pay attention to, in reconditioning blade tip chamfering, to be ground on main cutting edge, making the anterior angle of main cutting edge inclined in this way Greatly, drilling is directly affected.

At present, the output axis connection of drill bit and drilling machine mainly using flanged joint and by bolt, screw or is led to Cross pin connection.But use and connected with upper type, after drill bit is fixed with drilling machine, dismounting is inconvenient, takes time and effort, and the effect that drills Fruit is undesirable, increases the burden of staff.
