Abstract
The utility model relates to a gear hobbing clamp, in particular to a small-bore gear hobbing clamp for a numerical control gear hobbing machine, which solves the problem that the traditional small-bore gear is incapable of realizing gear hobbing on the numerical gear hobbing machine. The small-bore gear hobbing clamp for the numerical control gear hobbing machine comprises an upper pressing piece, a lower pressing piece and a base which are arranged in sequence from top to bottom; a gear-hobbing mandrel is fixed between the lower pressing piece and the base; the gear-hobbing mandrel consists of a base and a mandrel which is fixed in the center of the base and penetrates out of the lower pressing piece and the upper pressing piece upwards; and a pressing nut is screwed on the mandrel at the upper side of the upper pressing piece. The small-bore gear hobbing clamp is reasonable and reliable in structure design, greatly increases the small-bore gear hobbing size stability, reduces the surface roughness, shortens the machining time, effectively improves the production efficiency and has the advantages of simple structure, convenience for operation and low cost.
Description
Technical field
The utility model relates to gear gear hobbing anchor clamps, is specially a kind of chain digital control gear hobbing machine with small-bore gear gear hobbing anchor clamps.
Background technology
Gear class workpiece gear hobbing at present owing to receive the restriction of hobbing machine structure, is processed on general hobbing machine small-bore (diameter of bore is less than 28mm) workpiece usually; Large aperture (diameter of bore is greater than 28mm) workpiece is processed on chain digital control gear hobbing machine usually.
General hobbing machine is because the hobboing cutter rotating speed is lower, and the workpiece surface roughness that processes is bad, and process time is longer; The workpiece feeding is scurried cutter and all need manually be carried out, and it is big to process workpiece size (common normal) scattered error, and workpiece quality is unstable, for the high workpiece of required precision, can not satisfy drawing requirement after the gear hobbing.
Chain digital control gear hobbing machine hobboing cutter rotating speed is higher, the workpiece feeding, and scurrying cutter all has numerical control program control, and the quality stability that processes workpiece is higher, and process time is short.But owing on the chain digital control gear hobbing machine base worktable hydraulic jack is arranged; It need be that the pull bar of M20 (hydraulic jack diameter of thread M20) couples together with a diameter minimum with gear hobbing anchor clamps and hydraulic jack; Consider the influence of wall thickness of gear hobbing axle again; When hole dimension in the workpiece during less than 28mm, this processing mode just can not adopt.
Summary of the invention
The utility model can't provide a kind of chain digital control gear hobbing machine with small-bore gear gear hobbing anchor clamps in the problem of chain digital control gear hobbing machine upper rolling tooth in order to solve existing small-bore gear.
The utility model is to adopt following technical scheme to realize: chain digital control gear hobbing machine is with small-bore gear gear hobbing anchor clamps; Comprise the last compressing member that sets gradually from top to bottom, following compressing member and base; Be fixed with the gear hobbing axle between following compressing member and the base; The gear hobbing axle is made up of base and the axle that is fixed on center and upwards passes down compressing member and last compressing member, is screwed with clamp nut on the axle of last compressing member upside.
During to small-bore gear (workpiece) gear hobbing, the end face of compressing member and workpiece contact portion under the first centering; The cylindrical of centering gear hobbing axle then guarantees that end face run-out and cylindrical are beated to be not more than 0.005mm; Then workpiece to be processed is installed on the gear hobbing axle; Install compressing member at last, by hand tighten clamp nut, press on the lathe toply, access program, start lathe, accomplish workpiece processing, having overcome existing small-bore gear can't be in the problem of chain digital control gear hobbing machine upper rolling tooth.
The utility model reasonable in design is reliable, makes small-bore gear gear hobbing dimensional stability significantly improve, and surface roughness has shortened process time when reducing, and has improved production efficiency effectively, has advantage simple in structure, easy to operate and that cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the last compressing member of 1-, compressing member under the 2-, 3-base, 4-gear hobbing axle, 5-clamp nut.
The specific embodiment
Chain digital control gear hobbing machine is with small-bore gear gear hobbing anchor clamps; Comprise the last compressing member 1 that sets gradually from top to bottom, following compressing member 2 and base 3; Be fixed with gear hobbing axle 4 between following compressing member 2 and the base 3; Gear hobbing axle 4 by base be fixed on center and upwards pass down compressing member 2 and the axle of last compressing member 1 is formed, be screwed with clamp nut 5 on the axle of last compressing member 1 upside.
In the practical implementation process, the base and the axle of gear hobbing axle 4 are structure as a whole.
