Abstract
The utility model discloses a welding type adjustable reamer. The reamer comprises a reamer body, a blade and a cooling water hole, wherein the blade is welded at the front end of the reamer body, and the cooling water hole is formed in the reamer body and coaxial with a rotation axis. According to the reamer, high-speed and high-precision machining of the reamer can be realized, by the aid of the diameter-adjustable structure, the manufacturing precision of the reamer is ensured, tool abrasions can be compensated, and the service life of the reamer can be prolonged.
Description
Technical field
The utility model relates to a kind of welded type expansion reamer, especially a kind of welded type expansion reamer being applied in mechanical processing industry.
Background technology
Reamer in mechanical processing industry mostly is low speed, low precision reamer at present.Fraising precision is subject to directly affecting of reamer manufacturing equipment completely, after tool diameter precision can not reach the required precision of processed hole or diminish due to tool wear diameter, cannot carry out the compensation of tool diameter.In addition, owing to being subject to the restriction of solder technology, traditional welding formula reamer can not carry out PVD(physical deposition coating), process velocity and the service life of greatly having reduced reamer.
Summary of the invention
The utility model object is: a kind of welded type expansion reamer is provided, and each geometric angle of cutting edge is designed
The technical solution of the utility model is: a kind of welded type expansion reamer, it comprises: cutter hub, be welded on the blade of cutter hub front end and be positioned at the inner and cooling water hole coaxial with axis of rotation of cutter hub.
On the basis of technique scheme, further comprise attached technical scheme:
Described matrix, the secondary cutting portion that is arranged on main cutting portion on matrix, is arranged on matrix and is connected with main cutting portion antarafacial.
Described main cutting portion comprise the first main cutting face and with not coplanar the second main cutting face of the first main cutting face, and secondary cutting portion comprises circular arc chamfered edge and the secondary cutting face between the second main cutting face and circular arc chamfered edge being connected with the first main cutting face.
The area of described the second main cutting face is greater than the area of the first main cutting face, and is less than the area in secondary cutting face.
It further comprises the screw that is positioned at cutter hub front end center and is the hexagonal conical surface and adjusts reamer diameter.
Described blade is carbide chip or ceramic tip or polycrystalline diamond blade or cubic boron nitride blade.
The utility model advantage is:
The utility model is applied widely, as lathe, milling machine, drilling machine, machining center, special structural design can realize high speed, the high accuracy processing of reamer, and diameter adjustable structure had not only guaranteed the accuracy of manufacture of this reamer but also the service life that can compensate tool wear and improve cutter.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the cross-sectional schematic of the first embodiment of the present utility model;
