Description
Technical field
This utility model relates to the technical field of fixture, especially a kind of Crankshaft Machining fixture.
Background technology
The use of bent axle is more and more extensive, is usually used on the production line such as steel rolling, papermaking, and bent axle is to ensure that product shearing quality
One of vitals；Processing with front crankshaft all external coordinations special purpose machine tool, cost is high, the cycle is long.Crankshaft Machining difficulty is main
It is embodied in two aspects: the structure of (1) bent axle is complicated, bad on lathe determines the centre of gyration；(2) machining crankshafts gyration
Time, inertia motion weight distribution inequality, affect machining accuracy, during bent axle fast rotation, also easily cause bent axle from clamping machine tool
Position comes off.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, it is provided that a kind of Crankshaft Machining
Fixture, can reduce cost in the quality of control Crankshaft Machining and cycle.
This utility model solves its technical problem and be the technical scheme is that a kind of Crankshaft Machining fixture, has and flies
Cut the rectangular jig body that the balance weight of bent axle is oppositely arranged, the thickness direction of described rectangular jig body offers and flying shear
The clamping through hole that the short axle outer end of bent axle matches, on the width of rectangular jig body, symmetry offers two and is positioned at clamping
The fixing screwed hole of through hole both sides, the thickness direction of rectangular jig body is further opened with consolidate corresponding with chuck position
Determine through hole and with the major axis axis of flying shear bent axle correction through hole point-blank.
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 fixture 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.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view in Fig. 1 at A-A.
Being numbered in accompanying drawing: 1, rectangular jig body, 2, clamping through hole, 21, rectangular through-hole, 22, manhole, 3, solid
Determine screwed hole, 4, fixed via, 5, correction through hole.
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 and Fig. 2, this utility model one Crankshaft Machining fixture, there is the balance weight with flying shear bent axle and be oppositely arranged
Rectangular jig body 1, the thickness direction of rectangular jig body 1 offers the dress that the short axle outer end with flying shear bent axle matches
Folder through hole 2, on the width of rectangular jig body 1, symmetry offers two fixing screwed holes being positioned at clamping through hole 2 both sides
3, the thickness direction of rectangular jig body 1 is further opened with the fixed via 4 corresponding with chuck position and bent with flying shear
The major axis axis of axle correction through hole 5 point-blank.Clamping through hole 2 mainly by open top rectangular through-hole 21 and with
The manhole 22 that rectangular through-hole 21 is connected forms, and the central point of rectangular through-hole 21 is mutually overlapping with the central point of manhole 22
Closing, the width dimensions of rectangular through-hole 21 is less than the diameter dimension of manhole 22.The central point of clamping through hole 2, fixed via 4
The central spot of central point and correction through hole 5 is on same straight line.The axis of two fixing screwed holes 3 coincides, and circle
The central point of shape through hole 22 is positioned on the axis of fixing screwed hole 3.The diameter dimension of manhole 22 is more than fixed via 4
Diameter dimension, the diameter dimension of fixed via 4 is equal with the diameter dimension of correction through hole 5.
The operation principle of this Crankshaft Machining fixture is: first fixture is placed on the front end of the short axle of flying shear bent axle, will fly
The short axle cutting bent axle is clamped in clamping through hole 2, and utilizes two fastening bolts to wear top in two fixing screwed holes 3 respectively
The short axle sidewall of tight flying shear bent axle, recycling pin wears fixed via 4 and chuck so that fixture clamping is on lathe,
Overlapped by the axis of the axis of the major axis of externally measured instrumental correction flying shear bent axle with correction through hole 5 afterwards.Even if
The structure of bent axle is complicated, also can determine the centre of gyration on lathe；During machining crankshafts gyration, inertia motion weight is distributed
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 control
The quality of Crankshaft Machining and cycle, reduce cost.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people
Member can carry out various change and amendment completely in the range of without departing from this utility model technological thought.This reality
The content being not limited in description by novel technical scope, it is necessary to determine its technology according to right
Property scope.
