Description

It is a kind of to be bored from clamping hard alloy crown gear
Technical field
The utility model is related to a kind of from hard alloy crown gear brill is clamped, belong to Machining Technology for Cutting field.
Background technology
Drill bit is that drilling goes out the cutter of cylindrical cavity, the material of drill bit on workpiece or solid material by rotary cutting Mainly there are carbon tool steel, high-speed steel and a hard alloy steel, drill bit is harder than workpiece to be machined, sharper keen could pass through rotation Turn cutting or rotary squeezing drilling go out circular hole, usual high-speed steel than carbon tool steel have better toughness, intensity, heat resistance and Higher cutting speed allowable, and hard alloy steel cutting ability is more preferable than the performance of high-speed steel, certain hard alloy steel it is tough Property and impact strength do not have that carbon tool steel and high-speed steel are good, therefore it is that hard alloy, drilling rod are other steel head occur The drill bit of material, that is, crown bores, it has taken into account the cutting ability of hard alloy and the structural behaviour of drilling rod, has played the excellent of a variety of materials Point, while crown is replaceable, therefore reduce processing cost, there are the problem of be that most of hard alloy crown drill bits are with drilling rod The punching connection that is screwed, usual drilling rod is elongated, and the strength and stiffness of drilling rod are greatly reduced after punching.
The content of the invention
The utility model aim be to provide it is a kind of bore from clamping hard alloy crown gear, pass through the convex of line convex body and line card slot Concave surface is engaged and holding tank flexible deformation is fixedly clamped blade, reaches the intensity and just for not punching and weakening drilling rod, not reducing drilling rod The purpose of degree.
The technical solution adopted in the utility model is:It is a kind of to be bored from clamping hard alloy crown gear, including carbide chip 1 With steel drilling rod 2, the carbide chip 1 includes blade base 11, cutting edge 12, line convex body 13 and pin 14, the steel Matter drilling rod 2 includes holding tank 21, line card slot 22, pin hole 23, spiral chip flute 24 and drillstock 25;
11 front end of blade base is provided with cutting edge 12, and end is connected with pin 14, and blade base 11 is at pin 14 A side surface be equipped with line convex body 13;
The front end of the steel drilling rod 2 is provided with holding tank 21, and holding tank 21 is internally provided with line card slot 22, the end of holding tank 21 End is connected with pin hole 23, and the outside of steel drilling rod 2 is equipped with spiral chip flute 24, and the end of steel drilling rod 2 is connected with drillstock 25.
Further, the blade base 11 coordinates with 21 transition of holding tank, and pin 14 coordinates with 23 transition of pin hole, clamping Slot 21 and 23 position-limiting action of pin hole cause blade 1 that can only be moved axially with drilling rod 2 along pin hole 23, and the line on blade base 11 is convex Body 13 is stuck in the line card slot 22 of 21 inner surface of holding tank of drilling rod 2, and engaging blade 1 by male and female face is fixedly connected on brill On bar 2.
The operation principle of the utility model is:Using blade base 11 and holding tank 21 be bonded and pin 14 and pin hole 23 Fitting limit blade 1 and drilling rod 2 and only move axially a relative motion degree of freedom, utilize line convex body 13 and line card slot 22 Male and female face contact fitting engagement limitation blade 1 and the freedom of axial movement of drilling rod 2 blade 1 is fastened on On drilling rod 2, at the same holding tank 21 is subject to that the line convex body 13 on blade base 11 acts on the active force of line card slot 22 and there are one Fixed flexible deformation achievees the purpose that the blade 1 that is effectively fixedly clamped by 21 flexible deformation clamping blade matrix 11 of holding tank, rises To from clamping action.
The beneficial effects of the utility model are:Fitting is contacted using the male and female face of the line card slot of the line convex body and drilling rod of blade Engagement fixes blade and drilling rod, while using the flexible deformation clamping blade of slip slot, eliminates in blade and brill Punching is connected with screw-nut on bar, is reduced the damage of the strength and stiffness to blade and drilling rod, is not connected with bolt and nut The problem of chip removal is not smooth in drilling processing can also be reduced.In addition it is quick that the utility model has the advantages of convenient installation, and service efficiency is high.
