Abstract
The utility model relates to a welded type replaceable milling cutter. The welded type replaceable milling cutter comprises a cutter head and a cutter handle, wherein the upper end surface of the cutter head is provided with a trapezoid cutter head joint part, the outer surface of the cutter head joint part is a fit surface at the gradient of 2 degrees, a joint groove is formed in the lower end surface of the cutter handle, a pin hole is formed in the side wall of the joint groove which is trapezoid, the joint groove and the cutter head joint part are matched with each other and are fixedly connected with the cutter handle and the cutter head, and the cutter head is a full-tungsten-steel ball milling cutter head. Since the cutter handle of the milling cutter is reusable, only the cutter head needs to be replaced after the cutter head is worn, so that the use amount of a hard alloy material is reduced greatly and simultaneously the requirement on reduction of the cutter cost is met; in addition, due to the good fitting of the cutter head joint part and the joint groove of the cutter handle, the excellent concentricity and the excellent rigidity of the cutter handle and the cutter head after welding can be guaranteed.
Description
Technical field:
The utility model relates to the cutter in a kind of machining, relates in particular to the interchangeable milling cutter of a kind of welded type.
Background technology:
Milling cutter, for Milling Process, have the rotary cutter of one or more cutters tooth.During work, each cutter tooth cuts the surplus of workpiece successively off and on.Milling cutter is mainly used in processing plane, hole milling, step, groove, profiled surface and cut-out workpiece etc. on milling machine.
At present, because the paces of mechanization degree development are very fast, requirement on machining accuracy to hole in being applied to machining is higher, particularly to the processing of deep hole, because regular turning tool can't arrive requirement on machining accuracy, just used milling cutter, but common milling cutter is when the practical operation deep hole, will be according to actual conditions, produce one the milling cutter of length-specific according to the degree of depth in hole, when operation, milling cutter connects electric machine main shaft, in the situation that high speed rotating, because cutter body is longer, when running into the higher workpiece of mechanical hardness, be easy to produce and collapse the cutter phenomenon, enlarged the cost input, and numerous clients are more and more higher for the requirement of cutter, a lot of customer requirements are not in the situation that affect the tool sharpening performance, reduce the production cost of cutter.
Summary of the invention:
The technical problem that the utility model solves is to provide a kind ofly can reuse handle of a knife, after tool bit abrasion only with changing cutter head, reduce costs the interchangeable milling cutter of welded type of input.
The technical scheme in the invention for solving the technical problem is: the interchangeable milling cutter of a kind of welded type, comprise cutter head and handle of a knife, the upper surface of described cutter head is provided with trapezoidal cutter head joint portion, the outer surface of cutter head joint portion is conjunction surface, the gradient of described conjunction surface is 2 °, and described handle of a knife lower surface offers engagement groove, at the sidewall of engagement groove, offers pin-and-hole, described engagement groove is trapezoidal, and engagement groove matches and is fixedly connected with handle of a knife and cutter head with the cutter head joint portion.
Further, described cutter head is full wolfram steel rose cutter cutter head.
Further, the bottom of described handle of a knife is the plane section cone that gradient is 5 °.
The beneficial effects of the utility model: this milling cutter uses can reusable handle of a knife, after tool bit abrasion, can only change cutter head, greatly reduced so the raw-material use amount of carbide alloy, met the requirement that reduces the cost of charp tool simultaneously, and good the agreeing with of the engagement groove of the cutter head joint portion of cutter head and handle of a knife, can guarantee that after solder bond cutter head, handle of a knife have good concentricity and rigidity.
The accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of cutter head in the utility model;
Fig. 3 is the schematic diagram of handle of a knife in the utility model.
In figure: 1, cutter head 11, cutter head joint portion 12, conjunction surface 2, handle of a knife 21, engagement groove 22, pin-and-hole.
The specific embodiment:
The interchangeable milling cutter of welded type as Figure 1-3, comprise cutter head 1 and handle of a knife 2, the upper surface of described cutter head 1 is provided with trapezoidal cutter head joint portion 11, the outer surface of cutter head joint portion 11 is conjunction surface 12, the gradient of described conjunction surface 12 is 2 °, and described handle of a knife 2 lower surfaces offer engagement groove 21, at the sidewall of engagement groove 21, offers pin-and-hole 22, described engagement groove 21 is trapezoidal, and engagement groove 21 matches and is fixedly connected with handle of a knife 2 and cutter head 1 with cutter head joint portion 11.
Further, described cutter head 1 is full wolfram steel rose cutter cutter head.
Further, as shown in Figure 3, the bottom of described handle of a knife 2 is the plane section cone that gradient is 5 °.
This milling cutter uses can reusable handle of a knife 2, after cutter head 1 wearing and tearing, can only change cutter head 1, greatly reduced so the raw-material use amount of carbide alloy, met the requirement that reduces the cost of charp tool simultaneously, and good the agreeing with of the engagement groove 21 of the cutter head joint portion 11 of cutter head 1 and handle of a knife 2, can guarantee that after solder bond cutter head 1, handle of a knife 2 have good concentricity and rigidity.
It is emphasized that, it is more than better implementation column of the present utility model, not the utility model is done to any type of restriction in appearance, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
