Description
Technical field
The utility model relates to a kind of anchor clamps, and particularly a kind of clamping automobile synchronizer internal tooth casing carries out the anchor clamps of surface cut processing.
Background technology
Because the outer surface of synchronizer gear sleeve is provided with groove, in the groove of finished surface, need the synchronized internal tooth casing be fixed on the anchor clamps with anchor clamps, uses the groove of its outer surface of machined into again.Existing anchor clamps are the scroll chuck (see figure 1), the synchronized internal tooth casing is sleeved on three claws processes.Use such anchor clamps processing,, be prone to cause the distortion of synchronized internal tooth casing, fragile on the other hand internal tooth on the one hand because calibration is inhomogeneous.
The utility model content
The utility model technical problem to be solved be to provide a kind of simple in structure, can not cause the internal tooth casing distortion, do not damage the synchronized internal tooth casing clamp for machining of internal tooth.
The technical scheme of the utility model is following: a kind of synchronized internal tooth casing clamp for machining comprises cone mandrel, fan-shaped awl tooth cover, packing washer, nut, spring and axial location cover; The conical tooth cover of said fan-shaped awl tooth cover for surrounding by three fanning strips; Said cone mandrel comprises taper shank, establishes big step at the big end of taper shank, establishes small stair on the right side of big step, on small stair, establishes cone; The said fan-shaped awl tooth cover of the cone outerwrap of said cone mandrel; The heavy caliber end of said fan-shaped awl tooth cover stretches in the axial location cover, and said axial location cover is through on the small stair that is bolted to cone mandrel, and the right side of the left side of said axial location cover and the big step of cone mandrel is close to; Be equipped with annular groove on the external peripheral surface of the left and right end of said fan-shaped awl tooth cover, in this annular groove, retainer spring be housed; The small end of the cone of said cone mandrel stretches out fan-shaped awl tooth cover, and is locked by the screw rod and the nut of said cone small end.
Adopt technique scheme, be inserted in the lathe spindle taper shank and locking, the spline tooth of fan-shaped awl tooth cover outer surface and the internal tooth engagement of synchronized internal tooth casing; In processing; The synchronized internal tooth casing is sleeved on fan-shaped awl tooth puts also tightening nuts, cone puts fan-shaped awl tooth cover tensioner thereby the synchronized internal tooth casing is fixed on fan-shaped awl tooth firmly; Because the external tooth engagement of the internal tooth of synchronized internal tooth casing and fan-shaped awl tooth cover; Can protect the internal tooth of synchronized internal tooth casing like this, prevent that internal tooth is damaged, can also prevent the distortion of synchronized internal tooth casing.
In technique scheme, be provided with packing washer between said fan-shaped awl tooth cover and the nut.
In technique scheme, said taper shank is a Morse taper shank.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, easy to use, can prevent effectively that the synchronized internal tooth casing is out of shape, avoids the damage of the internal tooth of synchronized internal tooth casing.The anchor clamps of the utility model can also be used for the processing of other thin-walled internal tooth casings.
Description of drawings
Fig. 1 is the structural representation before improving;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the rotation diagram of the dextrad view of fan-shaped awl tooth cover in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Shown in Fig. 2-3, the utility model is made up of cone mandrel, fan-shaped awl tooth cover 3, packing washer 4, nut 5, spring 6, screw rod and axial location cover 7.The said fan-shaped awl tooth cover 3 conical tooth cover for being surrounded by three fanning strips, said fanning strip are divided equally by an external splines endoporus tapered sleeve and are cut into 3 five equilibriums and obtain.Said cone mandrel comprises Morse taper shank 1a, establishes the big step 1b of step at the big end of taper shank 1a; Small stair 1d is established on right side at big step 1b; On small stair 1d, establish cone 1c, the large end face of cone 1c contacts with small stair 1d, the said fan-shaped awl tooth cover 3 of the cone 1c outerwrap of said cone mandrel; Said cone 1c and fan-shaped awl tooth overlap 3 taper fit; The heavy caliber end of said fan-shaped awl tooth cover 3 stretches in the axial location cover 7, and said axial location cover 7 is through on the small stair 1d that is bolted to cone mandrel, and the left end of said axial location cover 7 is close on the right side of big step 1b of cone mandrel; Be equipped with annular groove on the external peripheral surface of the front and back end of said fan-shaped awl tooth cover 3, retainer spring 6 is housed in this annular groove; The small end of the cone 1c of said cone mandrel stretches out fan-shaped awl tooth cover 3, and is locked by the screw rod and the nut 5 of said cone 1c small end, is provided with packing washer 4 between said fan-shaped awl tooth cover 3 and the nut 5.
During use, 2 pairs of teeth of synchronized internal tooth casing are packed on the fan-shaped awl tooth cover 3 and are close to axial location and overlap 7 right sides, tightening nuts 5 makes packing washer 4 promote fan-shaped awl tooth cover 3 and moves left and even spreading the swelling workpiece to cone mandrel; Counter-rotating nut 5 when unclamping because retainer spring 6 contractions, makes fan-shaped awl tooth cover 3 move right and draw in to cone mandrel, to unclamp workpiece.
