Abstract
The utility model provides a crisscross hobbing cutter of annular belongs to mechanical technical field. It has solved current hobbing cutter owing to receive the restriction of tooth wall thickness, not only processes also very high problem of the very big but also processing cost of the degree of difficulty. This crisscross hobbing cutter of annular includes the cutter body, cutter body center part has seted up and has seted up the keyway on shaft hole and the shaft hole inner wall, the external circumferential wall of cutter body goes up even distribution has a plurality of along cutter body axial extension and laevorotary tooth row, the tooth is arranged the cutting teeth that has a cutting edge by a plurality of and is constituteed and just form at the bottom of tooth top and the tooth, the crisscross distribution is each other arranged in proper order to adjacent tooth, it is corresponding at the bottom of the tooth that tooth top and adjacent tooth that the tooth was arranged were arranged, the interior angle that has flute and flute between adjacent tooth is arranged is 30 degrees, the radius that the flute bottom is fillet and fillet is 1.5mm. The utility model has the advantages of rational in infrastructure and can light process the modulus and be less than the 0.9mm gear.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of hobboing cutter, particularly the staggered hobboing cutter of a kind of annular.
Background technology
Hobboing cutter is according to the helical tooth wheel set theory of engagement, with the cutter of generating cutting pinion, add man-hour, hobboing cutter is equivalent to the very large helical gear of a helical angle, its number of teeth is the head number of hobboing cutter, and workpiece is equivalent to another helical gear, each other according to a pair helical tooth crop rotation spatial conjugate, rotate with fixing speed ratio, become tooth-formation of gear by the cutter tooth profile of tooth envelope of each adjacent position of cutting successively.
Along with high precision machines popularization and application, fine module gear is also applied more and more extensive thereupon.Because of the impact of prior art and production equipment, to such an extent as to the hobboing cutter of processing fine module gear is very difficult.When particularly processing the gear between modulus 0.1mm to 0.9mm, owing to being subject to the restriction of hobboing cutter tooth wall thickness, not only difficulty of processing is very large but also processing cost is also very high.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of rational in infrastructure and easily can process annular that modulus is less than 0.9mm gear and to interlock hobboing cutter.
The purpose of this utility model realizes by following technical proposal: the staggered hobboing cutter of a kind of annular, comprise cutter hub, described cutter hub centre offers axis hole and shaft hole inner wall offers keyway, the outer circle wall of described cutter hub is uniformly distributed with several axially to extend and left-handed tooth row along cutter hub, described tooth row is made up of several cutting teeths with blade and is formed at the bottom of tooth top and tooth, it is characterized in that, the interlaced distribution successively of described adjacent tooth row, tooth top on described tooth row is corresponding with at the bottom of the tooth on adjacent tooth row, between described adjacent tooth row, there is flute and the interior angle of flute is 30 degree, it is fillet and the radius of fillet is 1.5mm bottom described flute.
The two adjacent teeth row of the staggered hobboing cutter of this annular is interlaced successively, and the tooth top on tooth row is corresponding with at the bottom of the tooth on adjacent tooth row, when the tooth pitch of the two adjacent teeth groove formed after a wherein tooth row of this hobboing cutter carries out cutting to workpiece is d, then after the tooth row be adjacent cuts workpiece again, make its adjacent teeth apart from becoming 1/2d, therefore this hobboing cutter easily can process modulus is fine module gear between 0.1mm to 0.9mm.
In the staggered hobboing cutter of above-mentioned one annular, described tooth row number is 12.
In the staggered hobboing cutter of above-mentioned one annular, the tooth pitch between on described tooth row two adjacent cutting teeths is 3mm.
Compared with prior art, the staggered hobboing cutter of this annular easily can be processed modulus because its tooth row is interspersed successively and is less than 0.9mm gear.
Accompanying drawing explanation
Fig. 1 is the structural representation of the staggered hobboing cutter of this annular.
Fig. 2 is the front view of the staggered hobboing cutter of this annular.
In figure, 1, cutter hub; 2, axis hole; 3, keyway; 4, tooth row; 5, blade; 6, cutting teeth; 7, tooth top; 8, at the bottom of tooth; 9, flute.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As Fig. 1, shown in Fig. 2, the staggered hobboing cutter of this annular comprises cutter hub 1, cutter hub 1 centre offers axis hole 2 and axis hole 2 inwall offers keyway 3, the outer circle wall of cutter hub 1 is uniformly distributed with several axially to extend and left-handed tooth row 4 along cutter hub 1, tooth row 4 is made up of several cutting teeths 6 with blade 5 and forms at the bottom of tooth top 7 and tooth 8, the interlaced distribution successively of adjacent tooth row 4, tooth top 7 on tooth row 4 is 8 corresponding with at the bottom of the tooth on adjacent tooth row 4, between adjacent tooth row 4, there is flute 9 and the interior angle of flute 9 is 30 degree, it is fillet and the radius of fillet is 1.5mm bottom flute 9, tooth row 4 number is 12, tooth pitch between on tooth row 4 two adjacent cutting teeths 6 is 3mm.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more to employ at the bottom of cutter hub 1, axis hole 2, keyway 3, tooth row 4, blade 5, cutting teeth 6, tooth top 7, tooth 8 herein, the term such as flute 9, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
