Abstract
The utility model discloses a sphere worm wheel and worm rod vice hob, which is used for processing worm wheel and worm rod. The utility model comprises a knife body similar to a column shape, the circumference surface of the knife body is provided with twist grooves, a twist heave is formed among the twist grooves, the top of the twist heave on the direction of the axle line of the knife body is arc-shaped. The utility model takes the beneficial effects that: the twist knife and the worm wheel rotate together, a whole worm wheel can be processed with the worm wheel rotates continuously for one ring, because the on and off of the worm wheel and the knife body are finished in one step and without continue tuning on and off. The utility model has simple process, high efficiency and process intensity.
Description
Technical field
The utility model relates to a kind of device that is used for the machining worm wheel worm gear pair, the secondary hobboing cutter of specifically a kind of Hindley worm gear.
Background technology
Worm couple is widely used in the transmission system of machinery.At present, the machining worm wheel worm gear pair generally all is to adopt hilted broadsword processing, the processing of a tooth of a tooth.Process is, rotates hobboing cutter and process a tooth on worm gear, after the completion of processing hobboing cutter stopped and playback, rotates worm gear then to next tooth position, starts hobboing cutter and processes this tooth, and so repetition is up to all teeth completion of processing all.This method process is loaded down with trivial details, and efficient is low, and because each tooth is processing separately, its precision is also lower.In addition, existing hobboing cutter all is an one, and a tooth damages, and whole cutter has just been scrapped, and makes processing cost increase.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can once finish, efficient height, machining accuracy height, the secondary hobboing cutter of Hindley worm gear that processing cost is low.
The technical scheme that its technical problem that solves the utility model adopts is: the cutter hub that comprises near cylindrical, the circumferential surface of described cutter hub is provided with helical groove, form helical raised between the described helical groove, the line of the top of described helical raised on the cutter hub axis direction is arc.
Described cutter hub is made of at least two parts, studs with blade between the various piece of described cutter hub, and described blade is that the center is symmetrically distributed with the axis of cutter hub; Described blade outward flange is the zigzag that matches with the outward flange of described cutter hub, and the outward flange of described blade is a little more than the outer surface of described cutter hub.
The beneficial effect that the utility model produced is: spiral helicine cutter hub rotates with processed worm gear, worm gear continuously revolves to turn around and can process a complete worm gear, because worm gear and cutter hub be constantly start and stop but go on foot and finish all, its processing is simple, efficient is high, and the machining accuracy height.In addition,, when certain breaks down, only need to change the blade that damages and get final product, do not influence the use of other cuttves, thereby reduced processing cost because blade is that burst is embedded on the cutter hub.The product surface of being produced is highly polished, saves time, and convenient, interchangeability is strong.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the cutaway view of the cutter hub of a kind of embodiment of the secondary hobboing cutter of Hindley worm gear of the present utility model;
Fig. 2 is the outline drawing of a kind of embodiment of the secondary hobboing cutter of Hindley worm gear of the present utility model;
Fig. 3 is an A-A cutaway view embodiment illustrated in fig. 2.
Among the figure: 1. cutter hub, 2. helical groove, 3. helical raised, 4. blade.
The specific embodiment
The cutter hub of the secondary hobboing cutter of Hindley worm gear as shown in Figure 1, cutter hub is similar to cylindrical, be provided with helical groove on its external peripheral surface, form helical raised between the helical groove, wherein the line of the top of helical raised on the cutter hub axis direction is arc.
As shown in Figures 2 and 3, cutter hub is made of eight parts, studs with blade between the various piece of cutter hub, and each blade is that the center is symmetrically distributed with the axis of cutter hub; The outward flange of blade is the zigzag that matches with the outward flange of cutter hub, and the outward flange of blade is a little more than the outer surface of described cutter hub.
During use, spiral helicine cutter hub is rotated with processed worm gear, worm gear continuously revolves to turn around and can process a complete worm gear.Since worm gear and cutter hub all constantly start and stop but a step finish, when processing, can wrap up five tooth productions at least, its processing simply, efficient is high, and the machining accuracy height.In addition,, when certain breaks down, only need to change the blade that damages and get final product, do not influence the use of other cuttves, thereby reduced processing cost because blade is that burst is embedded on the cutter hub.The product surface of being produced is highly polished, saves time, and convenient, interchangeability is strong.
Claims (2)
1, the secondary hobboing cutter of Hindley worm gear, it is characterized in that: the cutter hub that comprises near cylindrical, the circumferential surface of described cutter hub is provided with helical groove, forms helical raised between the described helical groove, and the line of the top of described helical raised on the cutter hub axis direction is arc.
2, the secondary hobboing cutter of Hindley worm gear according to claim 1, it is characterized in that: described cutter hub is made of at least two parts, studs with blade between the various piece of described cutter hub, and described blade is that the center is symmetrically distributed with the axis of cutter hub; Described blade outward flange is the zigzag that matches with the outward flange of described cutter hub, and the outward flange of described blade is a little more than the outer surface of described cutter hub.
