The traditional processing method of escape is on drilling machine, to adopt the processing mode of manual calibration to complete, and has that production efficiency is low, labor strength large, machining accuracy is difficult to the deficiency guaranteed, especially when producing in enormous quantities, and the drawback of more aobvious above-mentioned processing method.For above-mentioned deficiency, need be improved existing gear shaver escape processing unit (plant), make its accurate calibration automatically, to enhance productivity, to reduce labor strength, and improve machining accuracy, guarantee carrying out smoothly of production in enormous quantities.
For this reason, people's utility model a kind of gear shaver withdrawing hole processing device [Granted publication number is: CN202367237U], comprise drill bit device, universal dividing head rotation table device and PLC controller, drill bit device comprises drill bit and for driving the drill bit apparatus for controlling of lifting of drill bit lifting, the universal dividing head rotation table device comprises the index dial for place work piece, for the indexing motor that drives index dial to rotate, for the index dial lifting drive that drives the index dial lifting with for locking or unclamp the retaining mechanism of index dial, the PLC controller is controlled indexing motor, index dial lifting drive and retaining mechanism.
This gear shaver withdrawing hole processing device utilizes automatic control technology, makes the withdrawing hole manufacturing procedure of gear shaver realize automation, has effectively improved production efficiency, has alleviated workman's labour intensity, and has guaranteed machining accuracy.But it needs other lathe and frock processing, and processing difficulties and working (machining) efficiency are low, once locate inaccurately, the defective product rejection that causes of processing easily appears.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed that a kind of working (machining) efficiency is high, the special type hobboing cutter of the processing gear shaver of straight forming shaving cutter tooth profile and escape.
The purpose of this utility model can realize by following technical proposal:
The special type hobboing cutter of this processing gear shaver, comprise the cutter hub with axial bore, the circumferencial direction of described cutter hub is evenly distributed with some smear metal cutters tooth, it is characterized in that, the sidepiece of described smear metal cutter tooth have adopt the transposition design for processing the cutting edge of gear shaver involute profile, the top of described smear metal cutter tooth have along cutter hub, radially outward protrude for processing the grooving cutter tooth of gear shaver escape, the crown of described grooving cutter tooth is the fillet shape, and the side edge mouth of described grooving cutter tooth and chip pocket bottom land to be processed are tangent or crossing.
Add man-hour, can go out profile of tooth and the escape of gear shaver by the direct gear hobbing of this special type hobboing cutter, the crown of grooving cutter tooth is arranged to the fillet shape, chip pocket is being added to man-hour, can not destroy the involute profile of gear shaver, can guarantee the precision of the gear shaver that processes.
In the special type hobboing cutter of above-mentioned processing gear shaver, the shape of described grooving cutter tooth is calculated according to the degree of depth of chip pocket to be processed and the gear shaver rear required footpath of refacing, and the fillet size of described grooving cutter tooth crown is calculated according to the degree of depth of chip pocket to be processed and the gear shaver rear required footpath of refacing.
In the special type hobboing cutter of above-mentioned processing gear shaver, in described axial bore, there is keyway.The direction of keyway axially arranges along cutter hub.
Compared with prior art, the special type hobboing cutter of this processing gear shaver has the following advantages:
This special type hobboing cutter directly gear hobbing goes out profile of tooth and the escape of gear shaver, has reduced boring or groove milling operation, has improved working (machining) efficiency; And the crown of grooving cutter tooth is arranged to the fillet shape, and chip pocket is being added to man-hour, can not destroy the involute profile of gear shaver, can guarantee the precision of the gear shaver that processes.
