Abstract
The utility model discloses a hob coating an annular plane secondarily by a plane. An arc cogging, and a straight cogging corresponding to a tool-array are bored or milled on the middle body of the hob; a tool bit is finely cut out by linear cutting; the tool bit is impacted, located and welded on the outer side of a hob tooth by screws, then a special nc plane is used for coating a worm grinder for fine grinding; the two ends of the hob body are provided with adjusting gland bushes which are respectively screwed by screws. The hob coating an annular plane secondarily by a plane employing a fine hob tooth-array to weld the hob has the effects of fine locating, quick grinding, short manufacture period, high processing efficiency, time and labor saving, as well as high processing depth.
Description
Technical field
The utility model relates to a kind of worm gear process tool, especially plane-generated double enveloping enveloping worm hob.
Background technology
At present, worm gear hob is that the high-speed steel blade is weldingly fixed on the cutter tooth of hobboing cutter cutter hub, and cutter tooth can not accurately be located, and cumbersome when correct grinding puts the first edge on a knife or a pair of scissors, the abrasive dust amount is big, efficient is low, the making hobboing cutter cycle is long.
The utility model content
In order to overcome the deficiency that existing worm gear hob exists, the utility model provides a kind of novel plane-generated double enveloping enveloping worm hob, to solve problems such as existing cutter tooth location is inaccurate, abrasive dust is difficult, fabrication cycle is long.
The technical scheme that its technical problem that solves the utility model adopts is: the plane-generated double enveloping enveloping worm hob, it is to bore or mill out and the corresponding circular arc teeth groove of blade row, straight trough teeth groove on the middle hobboing cutter cutter hub, cutter head cuts out with line cutting precision, cutter head compresses tack welding with screw earlier and is connected on the cutter tooth outside, welding the back finish grindes on dedicated numerical control planar envelope worm grinder, there is the adjustment gland at the cutter hub two ends, twist with screw respectively.
The beneficial effects of the utility model are, plane-generated double enveloping enveloping worm hob, the good effect that adopts accurate cutter tooth row welding hobboing cutter be can accurately locate, grinding is quick, fabrication cycle is short, working (machining) efficiency is high, time saving and energy saving, machining accuracy is high.
