Description
Technical field：
The present invention relates to a kind of clamp that pinion cutter negative rake is ground in universal cutter grinder, for pinion cutter cutter tooth
The Precision Machining of different negative rakes, different ligament widths.
Background technology：
To prevent the generation of pinion cutter tipping phenomenon in Hardened gear face slotting, devise has inserting for negative rake along tooth form direction
Serrated knife, but pinion cutter cutter tooth negative rake difficulty of processing is big, has two kinds using processing method at present, and one is by along the negative of tooth form direction
Anterior angle grinds negative rake on rake face, and the pinion cutter edge strength that this processing method is processed is weak, it is impossible to solve the problems, such as tipping；Separately
A kind of method is to carry out the processing of cutter tooth negative rake using numerical control program in vertical machining centre, but due to pinion cutter hardness
High, teeth groove is narrow, can only be ground using cylinder emery wheel, and cylinder emery wheel diameter very hour abrasion of grinding wheel is serious, processing
Precision reduction；Just interfere in pinion cutter root when grinding wheel diameter is big, while the grinding wheel froth grinding vertical machining centre rail under mill
Road, destroys the precision of vertical machining centre.
The content of the invention：
The present invention is a kind of clamp that pinion cutter negative rake is ground in universal cutter grinder, solves current processing side
The problem that method is present.
The present invention is realized by following technical scheme：
A kind of pinion cutter negative rake clamp, including, it is alignment pin, handwheel, revolving body, rotating disk, nut, supporting plate, solid
Determine nut, chassis and bearing pin, handwheel is arranged on revolving body, and rotating disk is fixed on revolving body, nut, supporting plate are inserted to be processed
Serrated knife is fixed on rotating disk, and revolving body is arranged on chassis by bearing pin, and revolving body can be rotated relative to chassis, by fixing nut
Rotating disk and revolving body relative position can be fixed, revolving body center has eccentric throw with pinion cutter center to be processed, in revolving body
The heart is fixed on chassis with pinion cutter flank profil substitution arc center superposition to be processed, alignment pin, can be from pinion cutter teeth groove to be processed
Insert or pull out.
This method for grinding is simple, easy to operate, and emery wheel center need to be only adjusted in grinding with the fixture centre of gyration in same height
Degree, just can grind tooth top to the uniform pinion cutter cutter tooth negative rake ligament of tooth root width, while with before strength table centering pinion cutter
After end face, each depth of cut is controlled, it is ensured that uniformity of the pinion cutter per between cog negative rake ligament.
Brief description of the drawings：
Fig. 1 is structural representation of the invention；
Fig. 2 is the left view of Fig. 1.
Specific embodiment：
As shown in Figure 1-2, the present invention includes nut 1, alignment pin 2, key 3, handwheel 4, revolving body 5, rotating disk 6, nut 7, branch
Fagging 8, fixing nut 9, pad 10, chassis 11 and bearing pin 12, handwheel 4 are arranged on revolving body 5, and rotating disk 6 is fixed on revolving body 5
On, be fixed on pinion cutter to be processed on rotating disk 6 by nut 7, supporting plate 8, and revolving body 5 is arranged on chassis 11 by bearing pin 12,
Revolving body 5 can be rotated relative to chassis 11, can be fixed rotating disk 6 and the relative position of revolving body 5 by fixing nut 9, in revolving body 5
There is eccentric throw, the center of revolving body 5 and pinion cutter flank profil substitution arc center superposition to be processed in the heart, fixed with pinion cutter center to be processed
Position pin 2 is fixed on chassis 11, can be inserted or pull out from pinion cutter teeth groove to be processed.
During assembling, chassis 11 is linked together with revolving body 5 by fixing nut 9, pad 10, pin 12, handwheel 4 is led to
Cross key 3 to be connected on revolving body 5, and tightened by nut 1, rotating disk 6 is connected with revolving body 5, supporting plate 8 is connected with rotating disk 6, insert
Serrated knife is arranged in supporting plate 8 by nut 7, and alignment pin 2 is fixed on chassis 11.
The present invention is ground using saucer wheel.First, in being turned round using the centre of gyration of fixture revolving body 5 and pinion cutter
The skew of the heart, realizes the determination of pinion cutter flank profil substitution arc center to be processed；By the rotation of fixture revolving body 5, realize
The grinding of pinion cutter cutter tooth difference negative rake；Rotated by handle 4, alignment pin 2 is positioned, realize the cutter tooth indexing of pinion cutter.
Emery wheel center and the centre of gyration of fixture revolving body 5 are adjusted during grinding high in sustained height, it is ensured that pinion cutter negative rake ligament is from tooth
The uniformity of tooth root width is pushed up, while with after strength table centering pinion cutter front end face, controlling each depth of cut, it is ensured that pinion cutter
Per the uniformity of between cog negative rake ligament.
The present invention realizes optimal center of arc position really using the fixture centre of gyration and the skew of the pinion cutter centre of gyration
It is fixed；By the rotation of fixture revolving body, the grinding of pinion cutter cutter tooth difference anterior angle is realized；By rotatable handle, positioning finger setting,
Realize the cutter tooth indexing of pinion cutter.This operating method is simple, high with the fixture centre of gyration by adjusting emery wheel center in grinding
In sustained height, pinion cutter cutter tooth negative rake ligament can be made from tooth top to the uniform of tooth root width, while being inserted with strength table centering
After serrated knife front end face, each depth of cut is controlled, it is ensured that uniformity of the pinion cutter per between cog negative rake ligament, realize that pinion cutter is born
The processing of anterior angle.Have the characteristics that：
1) develop and anterior angle size is controlled by rotary clamp, knife is completed using making alignment pin be inserted in teeth groove after rotatable handle
The indexing of tooth, completes to be ground the grinding of negative rake from tooth top to tooth root by the rotary motion of emery wheel.
2) by adjusting emery wheel center and the fixture centre of gyration in sustained height, it is ensured that the negative rake ligament for grinding is from tooth top
To the uniformity of tooth root width, at the same every certain number of teeth emery wheel before pinion cutter standardized circular arc, observation substitution arc with gradually
Burst at the seams difference, makes cutter tooth negative rake ligament width uniform.
3) each depth of cut is controlled with strength table, to ensure pinion cutter per between cog negative rake ligament uniformity.
Embodiment 1：
One AA grades of Carbide Gear Shaping Cutter, material is YT758, and modulus is that the 6, number of teeth is 21,20 ° of pressure angle, negative rake
7 °, the tough bandwidth 1mm of negative rake, finish 0.8, when vertical machining centre processes Carbide Gear Shaping Cutter cutter tooth negative rake, sand
Wheel comes off seriously, causes ligament uneven, and grinding wheel froth grinds and hinders numerical control machine slide rail.Using present clip in multipurpose instrument (tool)
Grinding machine pinion cutter negative rake, it is simple to operate；And select diamond saucer wheel, it is to avoid and the coming off of emery wheel, meet
Pinion cutter negative rake ligament width 1mm, finish 0.8, the requirement of 7 ° of negative angle.
