Description
Technical field
The utility model relates to machining equipment field, is specifically related to a kind of hobboing cutter for turning tooth bar.
Background technology
Hobboing cutter is that cutter tooth makes the gear cutting tool of helical row along cylinder or circular cone, for pressing generating machining cylindrical gear, worm gear and other cylindrical toothed workpiece.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, 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.According to the difference of purposes, hobboing cutter is divided into gear hob, worm gear hob, non-involute generate hobboing cutter and single position hob etc.
In tooth bar rotary drive mechanism, widely, lathe, boats and ships, mining equiment, automobile steering device etc. have the application of rack-driving in the application of tooth bar.Particularly in automobile steering device, because the required precision of tooth bar is high, the processing of material difficulty, the geometry of whole toothed rack and geometric accuracy require to process at one time, so the production and processing requirement of cutter is strict.The production major part of current domestic automobile tooth bar adopts import cutter.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, designs a kind of hobboing cutter for turning tooth bar, in order to improve above-mentioned drawback.
For achieving the above object, the technical scheme that the utility model adopts is:
The utility model provides a kind of hobboing cutter for turning tooth bar, comprise ring-type cutter hub, the semi-circumference in described ring knife external week is upwards distributed with first cutter head at equidistant interval, depressed part is formed between described first cutter head, the blade place of described first cutter head is formed with multiple breach, and the side of described first cutter head is provided with the second cutter head of auxiliary described first cutter head turning.
Preferred technical scheme is, described breach is two.
Preferred technical scheme also has, and each described breach is other is formed with reinforcement.
Preferred technical scheme also has, and described secondary cutter head and described operator head are fitted.
Advantage of the present utility model and beneficial effect are:
1, first cutter head at equidistant interval is upwards distributed with in the semi-circumference in described ring knife external week, the processing to tooth bar can be realized, then can not cut metalwork in the position not arranging the first cutter head, and just can realize the cutting to metalwork in the position arranging the first cutter head, thus realize the object of manufacturing gear strip.Between described first cutter head, be formed with depressed part, the effect of depressed part is that the chip in turning process is flowed out along depressed part, can not affect the turnery of the first cutter head.Be formed with multiple breach at the blade place of described first cutter head, the cutting dynamics of the first cutter head to metalwork can be increased, make cutting effect better.Be provided with the second cutter head of auxiliary described first cutter head turning in the side of described first cutter head, serve the effect of auxiliary cutting.
2, two breach are set on the first cutter head, make the blade place of the first cutter head form three-stage structure, make the turning better effects if of the first cutter head when contact metal.
3, be formed with reinforcement each described breach is other, the effect of reinforcement first cutter head intensity can be played, ensure that blade can not burst apart damage easily.
4, described secondary cutter head and described operator head are fitted, make secondary cutter head play certain supporting role to operator head.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hobboing cutter for turning tooth bar of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Hobboing cutter is that cutter tooth makes the gear cutting tool of helical row along cylinder or circular cone, for by generating machining cylindrical gear, worm gear and other cylindrical toothed workpiece (see Gear Processing, gear).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, 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.According to the difference of purposes, hobboing cutter is divided into gear hob, worm gear hob, non-involute generate hobboing cutter and single position hob etc.
In tooth bar rotary drive mechanism, widely, lathe, boats and ships, mining equiment, automobile steering device etc. have the application of rack-driving in the application of tooth bar.Particularly in automobile steering device, because the required precision of tooth bar is high, the processing of material difficulty, the geometry of whole toothed rack and geometric accuracy require to process at one time, so the production and processing requirement of cutter is strict.The production major part of current domestic automobile tooth bar adopts import cutter.
In order to improve above-mentioned drawback, as shown in Figure 1, the utility model provides a kind of hobboing cutter for turning tooth bar, comprise ring-type cutter hub 1, the semi-circumference of described ring-type cutter hub 1 periphery is upwards distributed with first cutter head 2 at equidistant interval, be formed with depressed part 3 between described first cutter head 2, the blade place of described first cutter head 2 is formed with multiple breach 5, and the side of described first cutter head 2 is provided with the second cutter head 4 of auxiliary described first cutter head 2 turning.
First cutter head 2 at equidistant interval is upwards distributed with in the semi-circumference of described ring-type cutter hub 1 periphery, the processing to tooth bar can be realized, then can not cut metalwork in the position not arranging the first cutter head 2, and just can realize the cutting to metalwork in the position arranging the first cutter head 2, thus realize the object of manufacturing gear strip.Between described first cutter head 2, be formed with depressed part 3, the effect of depressed part 3 is that the chip in turning process is flowed out along depressed part 3, can not affect the turnery of the first cutter head 2.Be formed with multiple breach 5 at the blade place of described first cutter head 2, the cutting dynamics of the first cutter head 2 pairs of metalworks can be increased, make cutting effect better.Be provided with the second cutter head 4 of auxiliary described first cutter head 2 turning in the side of described first cutter head 2, serve the effect of auxiliary cutting.
Shown in an embodiment of the present utility model, described breach 5 is two.
First cutter head 2 arranges two breach 5, makes the blade place of the first cutter head 2 form three-stage structure, make the turning better effects if of the first cutter head 2 when contact metal.
Shown in an embodiment of the present utility model, each described breach 5 is other is formed with reinforcement 6.
Be formed with reinforcement 6 each described breach 5 is other, the effect of reinforcement first cutter head 2 intensity can be played, ensure that blade can not burst apart damage easily.
Shown in an embodiment of the present utility model, described secondary cutter head and described operator head are fitted.
Described secondary cutter head and described operator head are fitted, makes secondary cutter head play certain supporting role to operator head.
