Abstract

The utility model discloses a crankshaft keyseat fixture which comprises a fixture body bottom plate, wherein two V-shaped seats are symmetrically arranged on the upper surface of the fixture body bottom plate; an angle positioning structure and an axial positioning mechanism are arranged between the two V-shaped seats; hold-down devices are arranged on the V-shaped seats; the two V-shaped seats are slidingly connected with the fixture body bottom plate via guide keys; the angle positioning structure comprises a positioning seat; a positioning block is arranged on the positioning seat; the positioning seat is connected with a fixture body via screws; the axial positioning mechanism comprises an axial positioning seat; the axial positioning seat is fixed on the fixture body bottom plate via screws; the hold-down devices comprise pressure plates, movable pressure blocks and screw rods; the movable pressure blocks are articulated with the front surfaces of the pressure plates; and the screw rods pass through the pressure plates and are connected with the V-shaped seats via hinge pins. The crankshaft keyseat fixture can achieve machining of multiple crankshafts via simple adjustment, saves the tooling machining cost, and is better in machined product symmetry degree consistency and good in product quality stability.

Description

Crankshaft milling key groove clamp
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of crankshaft milling key groove clamp.
Background technology
At present, crankshaft milling key groove clamp is the concrete base plate of mounting clamp on platen, and two V-type seats are installed thereon, angle positioning device+mono-hold down gag, a length positioning device.Due to every kind of main bearing journal, rod journal and eccentric throw difference, every kind of bent axle needs a set of frock conventionally, can not realize flexible production, and processing cost is high; Due to the size dimension of main bearing journal, will directly have influence on the symmetry of crankshaft key slot simultaneously, therefore high to the requirement of trunnion location dimension, if trunnion size is unstable, will directly affect the symmetry of product.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of crankshaft milling key groove clamp is provided, and by simple adjusting, can realize the processing of multiple bent axle, saves frock processing cost; Because tool locating benchmark is consistent with product benchmark, converted products symmetry uniformity is better, and constant product quality is good.
The technical scheme that the utility model adopts is: a kind of crankshaft milling key groove clamp, comprise clamp body base plate, described clamp body plate upper surface is arranged with two V-type seats, between described two V-type seats, be provided with angle locator and axial positioning mechanism, wherein V-type seat is provided with hold down gag, two V-type seats are slidably connected by feather key and clamp body base plate, described angle locator comprises positioning seat, positioning seat is provided with locating piece, described positioning seat is connected with clamp body by screw, described axial positioning structure comprises axial location seat, axial location seat is fixed by screws on clamp body base plate, described hold down gag comprises pressing plate, active tongue piece and screw rod, described movable holddown is articulated with pressing plate front, screw rod is through pressing plate, and be connected with V-type seat by joint pin.
As preferably, described two V-type seats are installed on clamp body base plate by T-shaped slot bolt and nut.
As preferably, described screw rod is close to briquetting and is provided with nut.
The beneficial effects of the utility model are: two V-type seats are connected with clamp body base plate by feather key, can move easily.Angle locator and axial positioning structure can be respectively to angle with axially position, guarantee the precision of processing.Hold down gag, for fixation workpiece, avoids workpiece to be moved in process.
Accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the utility model left view.
In figure: 1, clamp body base plate; 2, V-type seat; 3, pressing plate; 4, active tongue piece; 5, joint pin; 6, screw rod; 7, nut; 8, feather key; 9, screw; 10, positioning seat; 11, locating piece; 12, axial location seat; 13, T-shaped slot bolt.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of crankshaft milling key groove clamp, comprise clamp body base plate 1, described clamp body base plate 1 upper surface is arranged with two V-type seats 2, between described two V-type seats 2, be provided with angle locator and axial positioning mechanism, wherein V-type seat 2 is provided with hold down gag, two V-type seats 2 are slidably connected by feather key 8 and clamp body base plate 1, described angle locator comprises positioning seat 10, positioning seat 10 is provided with locating piece 11, described positioning seat 10 is connected with clamp body by screw 9, described axial positioning structure comprises axial location seat 12, axial location seat 12 is fixed on clamp body base plate 1 by screw 9, described hold down gag comprises pressing plate 3, active tongue piece 4 and screw rod 6, described movable holddown is articulated with pressing plate 3 fronts, screw rod 6 is through pressing plate 3, and be connected with V-type seat 2 by joint pin 5.As preferably, described two V-type seats 2 are installed on clamp body base plate 1 by T-shaped slot bolt 13 and nut 7.As preferably, described screw rod 6 is close to briquetting and is provided with nut 7.
When use, axial location seat 12 is fixed on clamp body base plate 1, two V-type seats 2 move on clamp body base plate 1 by feather key 8, screw 9, determine the axial location of crankshaft journal.Angle location structure is arranged on to the below of bent axle first connecting rod axle journal, realizes the central plane angle requirement of crankshaft key slot central plane to trunnion and first connecting rod axle journal by the locating piece 11 of adjusting on angle positioning seat 10.
