Abstract

The invention discloses a universal hobbing device for a shaft gear, which comprises an assembling platform and a three-jaw chuck, wherein the assembling platform is composed of an upper plate, a rib plate, a lower plate and a cylinder, and the three-jaw chuck is mounted on the upper plate of the assembling platform through a bolt and a gasket. The universal hobbing device for the shaft gear has the advantages that: after the hobbing device is used for once mounting, aligning and correcting circle, a self-centering function of the three-jaw chuck is utilized to automatically correct a to-be-processed shaft gear; the positioning is accurate and quick; the structure is simple; the operation is convenient; the three-jaw chuck can be used for clamping the shaft gears in different sizes; the clamping is firm; the universality is high; and the product quality is ensured while the production efficiency is increased.

Description

A kind of general profile shaft type gear hobbing device
Technical field
The present invention relates to a kind of gear frock clamp, relate in particular to the device that a kind of clamp axis type gear carries out gear hobbing processing.
Background technology
Gear-hobbing machine is most widely used a kind of lathe in the gear cutting machine, can cut straight-tooth, helical teeth, roller gear on gear-hobbing machine, is applicable to the production of batch, small lot and single-piece.The frock clamp of gear-hobbing machine roughly is divided into two top types and a folder one top type according to its installation way at present.Mainly by jail, two top tops, this frock has strengthened the difficulty of clamping workpiece centering to two top type frocks, and the cutting force that gear-hobbing machine produces in hobbing process is large, assurance product quality that can not be intact; One folder, one top type mainly pushes up firm workpiece bottom cylindrical by Hough, the top upper surface centre bore that withstands of lathe, during this frock clamping axle type gear part, because axle type gear spare part outside measurement is bigger than normal, clamping is not firm, proofreaies and correct difficulty, in hobbing process, the suffered load of workpiece is bigger than normal, shakes, and profile of tooth produces deviation.
Summary of the invention
Goal of the invention: goal of the invention of the present invention provides a kind of general profile shaft type gear hobbing device, accurate positioning, quick, and simple in structure, easy to operate, clamping is firm, and highly versatile is enhanced productivity when guaranteeing product quality.
Technical scheme: a kind of general profile shaft type gear hobbing device of the present invention, comprise tooling platform and scroll chuck, described tooling platform is comprised of upper plate, gusset, lower plate and cylinder, and described scroll chuck is installed on the upper plate of tooling platform by screw and pad.The bottom cylindrical of axle type gear to be processed clamps by the claw of scroll chuck, and the upper surface centre bore withstands by lathe is top.
In order to prevent in the gear-hobbing machine hobbing process, because cutting force is excessive, tooling platform occurs to slide and affects axle type gear crudy, and the lower plate of described tooling platform is provided with through hole, by mounting screw in through hole tooling platform is fixed on the workbench.
For accurately calibration tool platform and scroll chuck, the center of described tooling platform upper plate is provided with screwed hole, carries out centering, school circle by the interim plug of installing in screwed hole.
In order to make things convenient for the lifting work of tooling platform, on the described tooling platform upper plate lifting screw is installed.
Beneficial effect: the present invention compares with existing axle type gear frock clamp, its distinguishing feature is the hobbing device once mounting, find accurately, behind the circle of school, utilize the Self-centering Action of scroll chuck automatically to be axle type gear centering to be processed, accurate positioning, quick, simple in structure, easy to operate, and by scroll chuck can the clamping different specification size the axle type gear, clamping is firm, and highly versatile is enhanced productivity when guaranteeing product quality.
Description of drawings
Fig. 1 is the longitudinal sectional view of embodiment of the invention tooling platform;
Fig. 2 is that embodiment of the invention tooling platform is along the top view of A-A line among Fig. 1;
Fig. 3 be the embodiment of the invention and lathe top in conjunction with the time vertical partial sectional view.
The specific embodiment
The present invention is described further below in conjunction with embodiment.
As shown in Figure 1 to Figure 3, tooling platform 1 is comprised of upper plate 11, gusset 12, lower plate 13 and cylinder 14, and lower plate 13 is provided with through hole 13a, and the center of upper plate 11 is provided with screwed hole 11a, and hoisting screw 2 is installed on the upper plate 11.Utilize hoisting screw 2 that tooling platform 1 is lifted into workbench, be placed on lathe top 5 under, by mounting screw in through hole 13a tooling platform 1 and workbench are linked together, scroll chuck 3 is placed on the upper plate 11 of tooling platform 1, the through hole that uses interim plug to pass scroll chuck 3 screws in the screwed hole 11a of upper plate 11, carry out centering, the school circle of tooling platform 1 and scroll chuck 3, centering, school circle are finished with screw 6 and pad 7 scroll chuck 3 and upper plate 11 are fixed, resume classes by plug, pull down at last plug.
During work, the lower end of axle type gear 4 to be processed is placed in the through hole of scroll chuck 3, the Self-centering Action of utilizing scroll chuck 3 is axle type gear 4 centerings to be processed and the cylindrical place, bottom that clamps axle type gear 4 to be processed by claw, lathe top 5 is withstood on the upper surface centre bore of axle type gear 4 to be processed, axle type gear 4 the most to be processed is fixed.
After the gear hobbing process finishing, change next axle type gear to be processed, need not again to package unit calibrate, the school circle, only need utilize the Self-centering Action of scroll chuck 3 is axle type gear 4 centerings to be processed, accurate positioning, fast, simple in structure, easy to operate, and by scroll chuck 3 can the clamping different specification size the axle type gear, clamping is firm, highly versatile is enhanced productivity when guaranteeing product quality.
