The utility model discloses it is few, with low costs that NULL is made to the blade, preparation simple process, long service life to effectively solve the big problem of prior art middle (center) bearing frictional resistance, the bearing rotates in a flexible way, and simple structure prolongs its life.
Description
Technical field
The utility model belongs to cutting-tool engineering field, is specifically related to a kind of cutter for cutting thin-wall copper pipe.
Background technology
The cutting of thin-wall copper pipe is processed by the cutter be installed on machine tool chief axis.In prior art, the blade of cutting thin-wall copper pipe generally adopts the cutter hub with bilateral shoulder to support, and is welded on by blade on cutter hub, and blade passes through the bearings of two series connection on machine tool chief axis, and is fixed by bearing enclose by nut.Its shortcoming is: one, during work, phase mutual friction inside two bearings, and nut is near bearing outer ring simultaneously, thus limits the rotation of bearing, strengthens bearing drag, reduces its service life; Two, blade adopts bilateral shoulder, and by cutter hub and blade welding, processing technology is complicated, and use material many, waste time and energy, service life is short; Three, the duplex bearing adopting series connection installed by blade, complex structure, and be difficult to the center ensureing the edge of a knife, manufacturing cost is high.Therefore be necessary to propose to improve.
Utility model content
The technical problem that the utility model solves: a kind of cutter for cutting thin-wall copper pipe is provided, cutter hub and blade are made integral structure, and form slim blade at cutter hub side convex shoulder, save material, cost is low, and manufacture craft is simple, long service life; And blade passes through a bearings on main shaft, is fixed on bearing, makes blade and bearing outer ring be fixed as one by collar by blade, efficiently solve the problem that prior art middle (center) bearing frictional resistance is large, bearing rotates flexibly, and structure is simple, low cost of manufacture, extends bearing service life.
The technical solution adopted in the utility model: for cutting the cutter of thin-wall copper pipe, there is blade, described blade by bearings on machine tool chief axis, described blade comprises cutter hub and blade, described blade is located on cutter hub outer cylinder surface and is formed integral structure, the two-sided cutting edge of described blade to be cross section be V-type, described cutter hub side is provided with convex shoulder, the side, outer ring of described bearing is shaped with flange, the outer cylinder surface of described bearing outer ring is provided with draw-in groove, is fixed on bearing by blade after collar engages with draw-in groove.
Wherein, described collar is C type structure, and the inner side of described C type structure is provided with multiple groove.
Further, described blade adopts high hardness wear-resisting type carbide alloy to make.
The utility model advantage compared with prior art:
1, cutter hub and blade are made integral structure, increase blade strength, increase the service life, service time is 5 times of existing blade;
2, the utility model is only at cutter hub side convex shoulder, makes it form slim blade, and save manufactured materials, processing cost is low, and manufacture craft is simple;
3, blade only uses a bearings on main shaft, efficiently solves in prior art the problem using duplex bearing frictional resistance large, and bearing rotates flexibly, and structure is simple, low cost of manufacture, extends bearing service life;
4, blade side is fixed on bearing by collar, and opposite side is located by flange, and blade and bearing outer ring are fixed as one, and replaces nut fixed form in original technology, and it rotates more flexible, smart structural design, long service life.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-6, embodiment of the present utility model is described.
For cutting the cutter of thin-wall copper pipe, as shown in Figure 1, 2, have blade 1, preferably, described blade 1 adopts high hardness wear-resisting type carbide alloy to make, and described blade 1 is supported on machine tool chief axis by bearing 2.As shown in Figure 3,4, described blade 1 comprises cutter hub 11 and blade 12, described blade 12 is located on cutter hub 11 outer cylinder surface and is formed integral structure, adds blade strength, extends its service life, the two-sided cutting edge of described blade 12 to be cross sections be V-type, described cutter hub 11 side is provided with convex shoulder 13, makes it form slim blade, has saved manufactured materials, processing cost is low, and manufacture craft is simple.As shown in Figure 5, the side, outer ring 21 of described bearing 2 is shaped with flange 23, the outer cylinder surface of described bearing 2 outer ring 21 is provided with draw-in groove 22, after collar 3 engages with draw-in groove 22, blade 1 is fixed on bearing 2, concrete, as shown in Figure 6, described collar 3 is C type structure, the inner side of described C type structure is provided with multiple groove 31, and groove 31 can increase the elastic bending of collar 3; 1, the utility model blade adopts a bearing 2 to be supported on main shaft, efficiently solves in prior art the problem using duplex bearing frictional resistance large, and bearing rotates flexibly, and structure is simple, low cost of manufacture, extends bearing service life; Meanwhile, blade 1 side is fixed on bearing 2 by collar 3, and opposite side is located by flange 23, blade 1 and bearing 2 outer ring 21 is fixed as one, replaces nut fixed form in original technology, and it rotates more flexible, smart structural design, long service life.
As shown in Figure 1, 2, during installation, bearing 2 and blade 1 inner hole are set with, make blade 1 side be close to the flange 23 of bearing 2, collar 3 is stuck in draw-in groove 22 and is fixed by blade 1 opposite side, is then arranged on machine tool chief axis with blade 1 by the bearing 2 be fixed as one.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalence changes done with content described in the utility model claim, all should be included within the utility model right.
