Abstract

The utility model relates to a tool for machine tool machining, in particular to a welding diamond drill reamer. The welding diamond drill reamer comprises a reamer body. The reamer body comprises a reamer head and a reamer handle. The outer end portion of the reamer head is a cutting part. The front end of the cutting part is a conical drill point. A spiral-shaped chip removal groove is formed in the outer circumference of the cutting part in the axial direction. A through groove is formed in the conical drill point in the radial direction. Two cutting teeth made of diamond blades are arranged inside the through groove in a butt-joint mode. The cutting teeth are welded inside an alloy block base body in an inlaid mode, wherein the alloy block base body is fixed inside the through groove. The tooth tips of the two butt-joint cutting teeth simultaneously pass the central axis of the reamer body. The welding diamond drill reamer has the advantages of being simple in structure and reasonable in design, improving machining efficiency, improving machining precision of workpiece surface, prolonging the service life of the reamer, saving machining cost, and being quite applicable to popularization and implementation.

Description

Welding diamond drill machine reamer
Technical field
The utility model relates to a kind of machine tooling cutter, particularly relates to a kind of welding diamond drill machine reamer.
Background technology
The kind of drill bit is more, for example fluted drill, reamer etc.Common drill bit is made up of drillstock and working portion, and wherein, working portion comprises cutting edge and targeting part again, and targeting part is provided with the helicla flute for chip removal.Because this structure of drill bit, it designs for boring roughing, and in order to make hole surface reach corresponding precision, also need fine finishining is carried out in the hole of boring, therefore, can only adopt other cutters that the hole is processed separately, but need to buy many cutter like this, be unfavorable for saving production cost, and change cutter and also waste time and energy, also be unfavorable for enhancing productivity.
China utility model patent ZL200820215406.1 discloses a kind of auger reamer, comprise shank and with the integrated working portion of shank, working portion comprises main cutting edge and spiral fluted targeting part, targeting part is provided with the burnishing-in sword, can on workpiece, once process required precision holes, be conducive to save cost and enhance productivity.But main cutting edge is in process, and cutting resistance is big, and the inner bore surface roughness of workpiece that processes is low, and the hole precision is low, and cutter life is low, simultaneously, has also limited production efficiency to a certain extent.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of reasonable in design is provided, and can satisfy process requirements, machining accuracy height, high life, the welding diamond drill machine reamer that production efficiency is high.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of welding diamond drill machine reamer, comprise cutter hub, cutter hub contains cutter head and handle of a knife, described cutter head outer end is cutting portion, and the cutting portion front end is the taper apex point, and described cutting portion excircle is axially arranged with the helical form chip area, position, described tapered bur tip radially is provided with groove, be provided with two cutting teeths of being made by diamond blade that butt joint arranges in the groove, on the alloy block matrix that described cutting teeth welding-on is fixed in groove, and two butt joint cutting teeth crowns are crossed the cutter hub central axis simultaneously.
Described cutting teeth blade relief angle β is 20 °.
The cone-apex angle α of described taper apex point is 120 °.
Described cutting teeth main cutting blade back taper is 0.08/100mm-0.1/100mm.
The helical angle of described helical form chip area is 27 °.
The beneficial effect of technical solutions of the utility model is:
1, structurally, the utility model welding diamond drill machine reamer designing is reasonable, at apex point place welding-on alloy block matrix, is convenient to process diamond blade cutter groove, and on the alloy block matrix welding-on diamond blade; The cutting teeth that two diamond blades the are made apex point that is symmetrically welded and dishes out, process main cutting blade is entirely diamond blade, and process has reduced cutting force, has further improved working (machining) efficiency.
2, structurally, cutting teeth blade described in the utility model arranges relief angle, further reduces the cutting resistance of process, prolongs the life-span of cutter, improves working (machining) efficiency; In addition, the cone-apex angle of described taper apex point is 120 °, and described cutting teeth main cutting blade back taper is 0.08/100mm-0.1/100mm, and the helical angle of described helical form chip area is 27 °, is conducive to reduce cutting resistance, helps chip removal, improves working (machining) efficiency.
3, to sum up, the utility model welding diamond drill machine reamer is simple in structure, reasonable in design, has improved working (machining) efficiency, has improved the machining accuracy of surface of the work, has prolonged cutter life, has saved processing cost, therefore, is very suitable for promotion and implementation.
