Abstract
The utility model discloses a taper shank slotting cutter blank which is a stepped shaft. The stepped shaft comprises a cutter tooth machining portion, a taper shank portion and clamping portions arranged at two ends and matched with a grinding machine clamp. The clamping portions are conical, the coaxiality can be ensured by means of matching of the conical clamping portions and the conical holes of the grinding machine clamp. Meanwhile, the blank fixing rigidity is better, the blank is stable during tooth grinding, and damage caused by the fact that a grinding machine is affected by impact force is avoided.
Description
Technical field
The utility model relates to a kind of machine tool, particularly the higher little modulus tapered shank cutter blank of a kind of precision.
Background technology
Tapered shank cutter is that shank is conical pinion cutter.The two ends that existing tapered shank cutter adds the blank in man-hour are columniform clamping part, clamping part center has locating hole, coordinate blank is fixed with the mandrel on grinding machine by locating hole, again blank is carried out to roll flute, the shortcoming of this structure is blank and grinding machine mandrel concentric locating inaccuracy, and machining accuracy is low, and the fixing rigidity of blank is inadequate simultaneously, in grinding machine process, blank is unstable, and the impulsive force that grinding machine is subject to blank easily produces destruction.
For above-mentioned deficiency, the applicant has invented the tapered shank cutter blank that a kind of novel precision is higher, to address the above problem.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of tapered shank cutter blank, and this tapered shank cutter blank adopts special method of clamping, better with grinding machine accurate positioning, rigidity.
Tapered shank cutter blank of the present utility model, described blank is multidiameter, comprises the clamping part for coordinating with fixture for grinding machine at cutter tooth processing department, taper shank portion and axle two ends, described clamping part is taper.
Further, the junction of described clamping part and cutter tooth processing department, taper shank portion is provided with fillet.
Further, the mutual mirror image setting of the clamping part at described two ends.
Further, the end of described clamping part is provided with chamfering.
The beneficial effects of the utility model: tapered shank cutter blank of the present utility model, described blank is multidiameter, comprise the clamping part for coordinating with fixture for grinding machine at cutter tooth processing department, taper shank portion and axle two ends, described clamping part is taper, coordinate with the taper hole of fixture for grinding machine by taper clamping part, can guarantee axiality, simultaneously the fixing good rigidly of blank, bloom stable when roll flute, grinding machine can not be subject to impulsive force and produce destruction.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as shown in the figure: the tapered shank cutter blank of the present embodiment, described blank is multidiameter, comprise the clamping part 3 for coordinating with fixture for grinding machine at cutter tooth processing department 1, taper shank portion 2 and axle two ends, described clamping part is taper, coordinates with the taper hole of fixture for grinding machine by taper clamping part, can guarantee axiality, blank good rigidly simultaneously, when roll flute, blank is more stable.
As the further improvement of technique scheme, described clamping part 3 is provided with fillet 31 with the junction of cutter tooth processing department 1, taper shank portion 2, and while avoiding roll flute, the stress of junction is concentrated and generation fracture.
As the further improvement of technique scheme, the mutual mirror image setting of clamping part 3 at described two ends, two clamping part mirror images arrange, and can make blank left-right replaceable on grinding machine.
As the further improvement of technique scheme, the end of described clamping part 3 is provided with chamfering 32, is convenient to blank to pack in the fixture on grinding machine.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
