Abstract
The utility model discloses a kind of Novel double bank milling cutter of machining worm, comprise cutter body and be evenly arranged at the milling cutter tooth of cutter body side, described milling cutter tooth comprise be arranged in parallel rough mill cutter tooth and finish-milling cutter tooth, describedly rough mill cutter tooth and finish-milling cutter tooth tooth pitch with worm tooth apart from identical, described in rough mill the transverse tooth thickness size 0.3mm fewer than the transverse tooth thickness size of described finish-milling cutter tooth of cutter tooth.The utility model structure is simple, can improve worm tooth-surface roughness and cutting-tool's used life.
Description
Technical field
The utility model belongs to worm screw process tool field, is specifically related to a kind of Novel double bank milling cutter of machining worm.
Background technology
Have a variety of in the processing method of low-modulus worm at present, such as: turning, grinding, roll extrusion, milling etc., method for turning precision is low and surface roughness is poor; Though method for grinding can reach high accuracy, efficiency is low, and manufacturing cost is high; Though rolling depression method efficiency is high, the accuracy of manufacture is low, and these are all the shortcomings of current processing method.
The situations such as employing method for milling precision is high and tooth-face roughness can reach Ra0.8, but is limited to the impact of the factor such as cutter material, process equipment, and milling cutter there will be cutter when processing steel part worm screw and is not durable, and tooth-face roughness is unstable.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of Novel double bank milling cutter of machining worm, and structure is simple, can improve worm tooth-surface roughness and cutting-tool's used life.
The technical scheme that the utility model adopts is: a kind of Novel double bank milling cutter of machining worm, comprise cutter body and be evenly arranged at the milling cutter tooth of cutter body side, described milling cutter tooth comprise be arranged in parallel rough mill cutter tooth and finish-milling cutter tooth, describedly rough mill cutter tooth and finish-milling cutter tooth tooth pitch with worm tooth apart from identical, described in rough mill the transverse tooth thickness size 0.3mm fewer than the transverse tooth thickness size of described finish-milling cutter tooth of cutter tooth.
As preferably, described in rough mill cutter tooth and finish-milling cutter tooth tooth pitch and worm tooth apart from being 2.513mm.
As preferably, described in rough mill cutter tooth transverse tooth thickness be of a size of 1.4mm, the transverse tooth thickness of described finish-milling cutter tooth is of a size of 1.7mm.
The beneficial effects of the utility model are:
1, because this uses, novel employing is thick, the double cutter tooth layout of finish-milling, and compared with prior art, this practicality achieves rough milling and finish-milling processing in a Milling Processes simultaneously, improves efficiency and the worm tooth-surface roughness of worm screw Gear Milling.
2, the utility model reasonable distribution milling surplus in a Milling Process, first toothrow is that rough milling removes most material, mill out worm screw crude green body shape, second toothrow is finish-milling processing, finish-milling is carried out to worm tooth-surface, because first row cutter tooth assume responsibility for main milling task, thus improve the life-span of second row cutter tooth.

In figure: 1, cutter body; 2, milling cutter tooth; 21, cutter tooth is rough milled; 22, finish-milling cutter tooth.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of Novel double bank milling cutter of machining worm, comprise cutter body 1 and be evenly arranged at the milling cutter tooth 2 of cutter body 1 side, described milling cutter tooth 2 comprise be arranged in parallel rough mill cutter tooth 21 and finish-milling cutter tooth 22, describedly rough mill cutter tooth 21 and finish-milling cutter tooth 22 tooth pitch with worm tooth apart from identical, described in rough mill the transverse tooth thickness size 0.3mm fewer than the transverse tooth thickness size of described finish-milling cutter tooth 22 of cutter tooth 21.As preferably, described in rough mill cutter tooth 21 and finish-milling cutter tooth 22 tooth pitch and worm tooth apart from being 2.513mm.As preferably, described in rough mill cutter tooth 21 transverse tooth thickness be of a size of 1.4mm, the transverse tooth thickness of described finish-milling cutter tooth 22 is of a size of 1.7mm.
The design adopts and parallel rough mills cutter tooth 21 and finish-milling cutter tooth 22, and rough mill modulus between cutter tooth 21 with finish-milling cutter tooth 22, tooth pitch, pressure angle are identical with worm screw.Rough mill and finish-milling from achieving a Milling Process.Because the first tooth is rough milling, assume responsibility for main cutting task, the second toothrow is finish-milling processing, only has a small amount of surplus, so substantially increase worm tooth-surface length and cutter life.
