The top plate of shaft tail end；Process die has the rectangular jig body that the balance weight with flying shear bent axle is oppositely arranged, rectangular jig
The clamping through hole that the short axle outer end with flying shear bent axle matches, the width of rectangular jig body is offered on the thickness direction of body
On direction, symmetry offers two fixing screwed holes being positioned at clamping through hole both sides, and the thickness direction of rectangular jig body is also opened
Be provided with the fixed via corresponding with chuck position and with the correction point-blank of the major axis axis of flying shear bent axle
Through hole.
The most specifically, in technique scheme, described clamping through hole mainly by the rectangular through-hole of open top and
The manhole composition being connected with rectangular through-hole, the central point of rectangular through-hole coincides with the central point of manhole, rectangle
The width dimensions of through hole is less than the diameter dimension of manhole.
The most specifically, in technique scheme, the described central point of clamping through hole, the central point of fixed via and
The central spot of correction through hole is on same straight line.
The most specifically, in technique scheme, said two is fixed the axis of screwed hole and is coincided, and circular
The central point of through hole is positioned on the axis of fixing screwed hole.
The most specifically, in technique scheme, the diameter dimension of described manhole is straight more than fixed via
Footpath size, the diameter dimension of fixed via is equal with the diameter dimension of correction through hole.
The beneficial effects of the utility model are: this Crankshaft Machining clamping device has the advantage that
Even if the structure of a bent axle is complicated, the centre of gyration also can be determined on lathe；
Two, during machining crankshafts gyration, inertia motion weight distributed uniform, do not affect machining accuracy, bent axle quickly returns
When turning, it is not easy to cause bent axle to come off from clamping machine tool position；
Three, the quality of control Crankshaft Machining and cycle can be reduced cost.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
See Fig. 1, Fig. 2 and Fig. 3, a kind of Crankshaft Machining clamping device, there is L-type lathe 1, fixing on the riser of L-type lathe 1
Chuck 2 is installed, chuck 2 is provided with the process die 3 of short spindle nose end for clamping flying shear bent axle, L-type machine
The top plate 4 of the long shaft tail end paralleled and for holding out against flying shear bent axle it is installed with riser in the bodyboard of bed 1；Technique mould
Plate 3 has the rectangular jig body 31 that the balance weight with flying shear bent axle is oppositely arranged, on the thickness direction of rectangular jig body 31
Offering the clamping through hole 32 that the short axle outer end with flying shear bent axle matches, on the width of rectangular jig body 31, symmetry is opened
Be provided with two fixing screwed holes 33 being positioned at clamping through hole 32 both sides, the thickness direction of rectangular jig body 31 is further opened with
Fixed via 34 that chuck position is corresponding and with the major axis axis of flying shear bent axle correction through hole point-blank
35.Clamping through hole 32 is mainly by the rectangular through-hole 321 of open top and the manhole 322 groups that is connected with rectangular through-hole 321
Becoming, the central point of rectangular through-hole 321 coincides with the central point of manhole 322, and the width dimensions of rectangular through-hole 321 is less than circle
The diameter dimension of shape through hole 322.The central point of clamping through hole 32, the central point of fixed via 34 and the central point of correction through hole 35
It is on same straight line.The axis of two fixing screwed holes 33 coincides, and the central point of manhole 322 is positioned at fixing
On the axis of screwed hole 33.The diameter dimension of manhole 322 is more than the diameter dimension of fixed via 34, fixed via 34
Diameter dimension is equal with the diameter dimension of correction through hole 35.
The operation principle of this Crankshaft Machining clamping device is: first process die 3 is placed on the short axle of flying shear bent axle
Front end, is clamped in the short axle of flying shear bent axle in clamping through hole 32, and utilize two fastening bolts wear respectively two fix
Holding out against the short axle sidewall of flying shear bent axle in screwed hole 33, recycling pin wears fixed via 34 and chuck so that fixture fills
Be clipped on lathe, finally by externally measured instrumental correction flying shear bent axle major axis axis with correction through hole 35 axis
Clamping after coincidence, counterweight adjusts suitable, checks each portion allowance, it is ensured that surplus is suitable, half finish turning each shelves circle size.I.e.
Just the structure of bent axle is complicated, also can determine the centre of gyration on lathe；During machining crankshafts gyration, inertia motion weight is divided
Join uniformly, do not affect machining accuracy, during bent axle fast rotation, be not easy to cause bent axle to come off from clamping machine tool position.Can be
