Abstract
The utility model discloses the eccentric collet of a kind of car, comprise taper shaft, terminal pad, adjustment disk and adjustment screw, described adjustment disk is also provided with axle sleeve, elastic jacket is provided with in described axle sleeve, the end cone match of described elastic jacket and axle sleeve, described axle sleeve is also provided with the nut promoting elastic jacket movement vertically.The eccentric collet of the utility model car, taper shaft is connected with lathe spindle, eccentric shaft is placed in elastic jacket, promote collet by rotating nut to move axially along axle sleeve, eccentric shaft can be fixedly clamped, then unclamp lock-screw and rotate adjustment screw promote adjustment disk move vertically, the eccentric segment of eccentric shaft is adjusted to lathe spindle coaxial, again by lock-screw secured adjusted dish, turnery processing can be carried out to eccentric shaft; By elastic jacket fixed eccentric shaft, clamping speed is fast, and axle sleeve center is adjustable, thus can process the eccentric shaft with different eccentric throw, and fixture versatility is good.
Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of fixture of turning eccentric shaft.
Background technology
In prior art, the clamp structure of turning eccentric shaft is comparatively complicated, and clamping speed is comparatively slow, and same fixture can only process the eccentric shaft with identical eccentric throw, and fixture versatility is poor.
Utility model content
In view of this, the purpose of this utility model is to provide the eccentric collet of a kind of car, to solve the problem that fixture clamping speed is slow, versatility is poor of turning eccentric shaft in prior art.
The eccentric collet of the utility model car, comprise the taper shaft be connected with lathe spindle, the front end of described taper shaft is provided with terminal pad, the end face of described terminal pad is provided with adjustment disk, described terminal pad is also provided with the adjustment screw promoting adjustment disk radially movement in radial both sides, adjustment disk is provided with the bar-shaped trough parallel with adjustment disk moving direction, in described bar-shaped trough, is provided with the lock-screw be fixed on by adjustment disk on terminal pad;
Described adjustment disk is also provided with axle sleeve, in described axle sleeve, is provided with elastic jacket, the end cone match of described elastic jacket and axle sleeve, described axle sleeve is also provided with the nut promoting elastic jacket movement vertically.
Further, described terminal pad is also provided with the guide plate coordinated with adjustment disk side slip.
Further, the endoporus base plate of described axle sleeve is provided with the Compress Spring promoting elastic jacket and reset.
The beneficial effects of the utility model:
The eccentric collet of the utility model car, taper shaft is connected with lathe spindle, eccentric shaft is placed in elastic jacket, promote collet by rotating nut to move axially along axle sleeve, eccentric shaft can be fixedly clamped, then unclamp lock-screw and rotate adjustment screw promote adjustment disk move vertically, the eccentric segment of eccentric shaft is adjusted to lathe spindle coaxial, again by lock-screw secured adjusted dish, turnery processing can be carried out to eccentric shaft; By elastic jacket fixed eccentric shaft, clamping speed is fast, and axle sleeve center is adjustable, thus can process the eccentric shaft with different eccentric throw, and fixture versatility is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the eccentric collet of the utility model car;
Fig. 2 is the right view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the eccentric collet of the present embodiment car, comprise the taper shaft 1 be connected with lathe spindle, the front end of described taper shaft is provided with terminal pad 2, the end face of described terminal pad is provided with adjustment disk 3, described terminal pad is also provided with the adjustment screw 4 promoting adjustment disk radially movement in radial both sides, adjustment disk is provided with the bar-shaped trough parallel with adjustment disk moving direction, in described bar-shaped trough, be provided with the lock-screw 5 be fixed on by adjustment disk on terminal pad;
Described adjustment disk is also provided with axle sleeve 6, in described axle sleeve, is provided with elastic jacket 7, the end cone match of described elastic jacket and axle sleeve, described axle sleeve is also provided with the nut 8 promoting elastic jacket movement vertically.
The eccentric collet of the present embodiment car, taper shaft is connected with lathe spindle, eccentric shaft is placed in elastic jacket, by the endoporus of elastic jacket and end face, eccentric shaft is positioned, promote collet by rotating nut again to move axially along axle sleeve, eccentric shaft can be fixedly clamped, unclamp lock-screw again, and rotate adjustment screw promote adjustment disk move vertically, the eccentric segment of eccentric shaft is adjusted to lathe spindle coaxial, again by lock-screw secured adjusted dish, turnery processing can be carried out to eccentric shaft, after machining, unclamp nut 8, along the conical surface outwards movement under elastic jacket promotes under own resilience, thus unclamp workpiece, pickup is convenient, by elastic jacket fixed eccentric shaft, clamping speed is fast, and axle sleeve center is adjustable, thus can process the eccentric shaft with different eccentric throw, and fixture versatility is good.
As the improvement to the present embodiment, described terminal pad is also provided with the guide plate 9 coordinated with adjustment disk side slip, is led by the movement of guide plate to terminal pad, can faster terminal pad be adjusted to the right place, be conducive to enhancing productivity.
As the improvement to the present embodiment, the endoporus base plate of described axle sleeve is provided with the Compress Spring promoting elastic jacket and reset, and after machining, promotes elastic jacket by Compress Spring, can better prevent elastic jacket clamping stagnation.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
