The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to Fig. 1 to Fig. 5, combined type pinion cutter of the present invention comprises the external splines pinion cutter 1 and the attenuated tooth pinion cutter 2 that are driven, stacked by same rotating shaft.Wherein, external splines pinion cutter 1 is provided with several first blades 3 along its cutter hub circumferencial direction, and attenuated tooth pinion cutter 2 is provided with several second blades 4 along its cutter hub circumferencial direction, and above-mentioned first blade 3 and second blade 4 are arranged on the same vertical plane.
In order to guarantee that first blade 3 and second blade 4 are positioned on the same vertical plane; Guarantee teeth directional symmetry precision; Combined type pinion cutter of the present invention also comprises the upper-lower position tool setting device one to one that makes above-mentioned first blade 3 and second blade 4, specifically comprises: be used to regulate first regulating handle 6 of first blade 3, second regulating handle 7 that is used to regulate second blade 4, two dial gauges 8 that distribute up and down, with external splines pinion cutter and the fixing trim ring 9 of attenuated tooth pinion cutter.In view of Fig. 1 is actually vertical view, so two dial gauges 8 are overlapping in the drawings, this is readily appreciated that, so do not give unnecessary details.
Before the processing beginning, at first, regulate the position of first blade 3 and second blade 4, the reading unanimity about making on two dial gauges 8 through first regulating handle 6 and second regulating handle 7 are finely tuned; Then, external splines pinion cutter 1 and attenuated tooth pinion cutter 2 are fixed, thereby effectively guarantee teeth directional symmetry precision with trim ring 9.
As a kind of concrete structure, external splines pinion cutter 1 is cutter down, and attenuated tooth pinion cutter 2 be a upper slitter, in the process under the workpiece contact earlier cutter contact upper slitter again.So for process, external splines orthodont and attenuated tooth process in one procedure, but specifically, be actually and process the external splines orthodont earlier, reprocess out attenuated tooth then on this basis.
As a kind of preferred, the top of external splines pinion cutter 1 cutter hub is formed with boss, and the bottom of attenuated tooth pinion cutter 2 cutter hubs is formed with groove, and boss embeds in the groove.So, guarantee that effectively external splines pinion cutter 1 and attenuated tooth pinion cutter 2 move simultaneously, motion mode comprises gyration and radial motion.
Certainly, first blade 3 and second blade 4 do not fit tightly together, also leave blank transition region between the two.
In order to understand the present invention better, below we sketch the course of work of combined type pinion cutter of the present invention:
Referring to Fig. 2, by following cutter, promptly external splines pinion cutter 1 moves downward vertically earlier, and contact workpiece also processes the external splines orthodont on workpiece; When external splines pinion cutter 1 continues to move downward, upper slitter, promptly attenuated tooth pinion cutter 2 also moves downward, and when touching the external splines orthodont that is processed to form before, just begins to be processed to form attenuated tooth.Attenuated tooth pinion cutter 2 moves downward the attenuate profile of tooth terminal 5 that needs processing until arriving, and state as shown in Figure 3 stops to process also withdrawing immediately, and the flange burr just is formed at the flank and the root at attenuate profile of tooth terminal 5.Next, the combined type pinion cutter is to the motion of the center of workpiece to be machined radial feed, to increase the cutting-in amount of space width and tooth root, the movement locus of process before repeating.
In process, the flange burr that external splines pinion cutter 1 produced when being used to process the external splines orthodont and machining away previous processing attenuated tooth, and the effect of attenuated tooth pinion cutter 2 is to process attenuated tooth, produces the flange burr simultaneously inevitably.When meeting the requirements of radial feeds, the combined type pinion cutter can carry out the revolution working motion that a circle does not have radial feeds more, and external splines pinion cutter 1 can cutting be removed the flange burr, owing to do not have radial feeds, so can not produce new burr yet.Through reciprocal revolution working motion and feed motion, reached the multiple action of processing orthodont, attenuated tooth and removal burr.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and the foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
