Part, ringfeder are internally provided with two-stage step structure, and first order step is fixed on the step surface of locating pad annulus maximum gauge, the
Two stage steps are positioned with pull rod cooperation.
The tail portion of the pull rod is connect with compression pump, and pull rod shaft offers and the matched cunning of positioning key in mandrel upwards
The stem of slot, pull rod is crosshead, and the protrusion for fixing ringfeder is provided on pull rod.
It is offered on the ringfeder and the matched cross bore of pull rod crosshead.
Compared with prior art, the utility model steps up workpiece by ringfeder, and the ringfeder of the present apparatus can
Dismounting not will produce clamping denaturation, and disclosure satisfy that the need of taper hole positioning due to being clamped using ringfeder to the thin-wall part of workpiece
It wants, it is convenient using present apparatus handling part, amount to beat 5~7 seconds, the difference of taper hole major diameter and path to part does not require,
The locating pad of this fixture is less than excircle of workpiece, and when processing can effectively avoid flange, this fixture is also applied to all same
In the conical surface positioning processing of class part, the economic benefit of generation is huge.
Further, the pull rod of the utility model is connect with compression pump, and when pressure release can release ringfeder, reduces worker's labour
Intensity.

Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of bipyramid expander clamp for machining, including mandrel 2, mandrel 2 are arranged with locating pad 1 outside, and workpiece passes through
Ringfeder 3 is fixed on the end face of locating pad 1, and ringfeder 3 steps up workpiece by pull rod 4, and excircle of workpiece is higher than locating pad 1.
Referring to Fig. 2 and Fig. 3, locating pad 1 is annulus, and several bolts hole for fixing 11 are offered on the end face of annulus,
Annulus is internally provided with three-level step structure.
Referring to Fig. 1, the outer surface of mandrel 2 contacts setting, 2 middle part of mandrel with the inner surface of 1 annulus minimum diameter of locating pad
The through-hole that pull rod 4 can be made to pass through is offered, is provided in through-hole for 4 positioning key 21 of steady brace.
Referring to Fig. 4 and Fig. 5,3 middle part of ringfeder offers the through-hole for enough passing through pull rod 4, and ringfeder 3 is by step surface 31 and determines
The position cooperation of pad 1 steps up workpiece, and ringfeder 3 is internally provided with two-stage step structure, and it is maximum that first order step is fixed on 1 annulus of locating pad
On the step surface of diameter, second level step is positioned with the cooperation of pull rod 4, is offered on ringfeder 3 matched with 4 crosshead 42 of pull rod
Cross bore 32.
Referring to Fig. 6 and Fig. 7, the tail portion of pull rod 4 is connect with compression pump, is offered in 4 axial direction of pull rod and positioning key in mandrel 2
