Abstract
The invention discloses a hob mounting structure which comprises a hob and a conical mandrel. A hob inner hole is arranged on the conical mandrel. The conical mandrel is fixed by the hob through nuts. Positioning wafers are further arranged between the hob and the nuts. The hob inner hole of the conical mandrel is positioned, so that a fit clearance butane the hob inner hole and the conical mandrel is eliminated. The conical mandrel is highly tapered and prevents the hob from being tilted during clamping. The hob is axially positioned through the positioning wafers at two ends of the conical mandrel. Therefore, accumulative pitch errors of a chip pocket caused by the clearance are basically eliminated. Cutter sharpening precision of a front tool surface of the hob is increased, cutter sharpening quality is guaranteed, and accordingly tooth profile errors in gears are decreased. Machined products are stable in stability, with the precision meeting the design requirement.
Description
Technical field
The present invention relates to a kind of mounting structure of hobboing cutter, belong to mechanical fixture technology field.
Background technology
Existing hobboing cutter clamping generally all is by cylindrical mandrel's clamping hobboing cutter, owing to exist fit clearance between hobboing cutter endoporus and the mandrel, namely exist the reference position error, because the existence of reference position error, must have influence on the accumulative pitch error of chip pocket behind the hobboing cutter sharpening, the most inner hole precision of hobboing cutter of supply is on the low side in the market, endoporus weares and teares after adding use a period of time, many hobboing cutter overproof of apertures are arranged, the fit clearance of hobboing cutter endoporus and mandrel then can't be eliminated by general cylindrical mandrel, the form of gear tooth that the part hobboing cutter is rolled out is overproof, does not reach needed instructions for use.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: the clamping structure that has proposed the hobboing cutter of a kind of precision height, long service life.
Technical solution of the present invention is achieved in that a kind of mounting structure of hobboing cutter, comprises hobboing cutter, taper mandrel; Described hobboing cutter endoporus is installed on the taper mandrel; Described hobboing cutter fixes the taper mandrel by nut; Also be provided with locating pad between described hobboing cutter and the nut.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The mounting structure of a kind of hobboing cutter of the present invention, by the taper mandrel hobboing cutter endoporus is positioned, to eliminate the fit clearance between hobboing cutter endoporus and the taper mandrel, because the tapering of this taper mandrel is larger, when clamping, pressed tiltedly for preventing hobboing cutter, taper mandrel two ends are implemented axial location with locating pad to hobboing cutter, by this design elimination the chip pocket accumulated pitch error that produces because of the gap, the sharpening precision of hobboing cutter rake face has improved, guaranteed grinding quality, thereby reduced the tooth-formation of gear error, the constant product quality that processes, precision has satisfied designing requirement.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the mounting structure of a kind of hobboing cutter of the present invention;
Wherein: 1, hobboing cutter; 2, taper mandrel; 3, nut; 4, locating pad.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is the mounting structure of a kind of hobboing cutter of the present invention, comprises hobboing cutter 1, taper mandrel 2; Described hobboing cutter 1 endoporus is installed on the taper mandrel 2; Described hobboing cutter 1 makes taper mandrel 2 fixing by nut 3; Also be provided with locating pad 4 between described hobboing cutter 1 and the nut 3.
During taper mandrel 2 clamping hobboing cutter 1 after use improving, taper mandrel 2 conical surfaces of first hobboing cutter 1 being packed into are with the hand push-tight of taking advantage of a situation, turn right-hand member nut 3, the locating pad 4 that promotes the right contacts with the right-hand member of hobboing cutter 1, then turns left side nut 3, promotes left end locating pad 4 hobboing cutter 1 is compressed.
The present invention program positions by 2 pairs of hobboing cutter 1 endoporus of taper mandrel, to eliminate the fit clearance between hobboing cutter 1 endoporus and the taper mandrel 2, because the tapering of this taper mandrel 2 is larger, when clamping, pressed tiltedly for preventing hobboing cutter 1, axial location is implemented with 4 pairs of hobboing cutters of locating pad 1 in taper mandrel 2 two ends, by this design elimination the chip pocket accumulated pitch error that produces because of the gap, the sharpening precision of hobboing cutter rake face has improved, guaranteed grinding quality, thereby reduced the tooth-formation of gear error, the constant product quality that processes, precision has satisfied designing requirement.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
