Abstract
The utility model discloses a kind of crankshaft milling flat fixture, including pedestal, be fixedly connected with location the bracer one for supporting crankshaft two end trunnion on pedestal, for supporting location bracer two and the pressure assembly down for depressing crankshaft two end trunnion of crank-shaft link neck, location bracer one is provided with the V-type supporting surface of symmetry.Lower pressure assembly includes connecting rod and the drive division of drive connection bar, is provided with briquetting below connecting rod.This fixture eliminates dividing head, two groups of locating pieces prop up the trunnion of bracer certain position crankshaft two end, trunnion is fixed by lower pressure assembly, location bracer two determines the height of the connecting rod neck of bent axle so that the trunnion axis of bent axle and connecting rod neck axis are in sustained height, so that it is determined that the milling position of bent axle microcephaly, milling again after bent axle is spun upside down 180 °, thus improve the symmetry of flat, convenient mounting and clamping, and improve clamping quality.
Description
Technical field
This utility model belongs to the technical field of machine cut clamp for machining, specifically, relates to a kind of bent axle
Milling flat fixture.
Background technology
The when of flat at machining crankshafts microcephaly, it would be desirable to bent axle is clamped, positions and demeanour,
What traditional processing mode was taked is " folder one top ", and needs indexing means in fixture, and this fixture is overall
Structure is complex, and parts are on the high side, and installation way is the most convenient, clamping difficult quality guarantee, processing
The flat symmetry gone out has much room for improvement.
Utility model content
For deficiency above-mentioned in prior art, this utility model provides a kind of crankshaft milling flat fixture, this folder
It is high that tool eliminates dividing head, convenient mounting and clamping and clamping quality, has reached higher flat symmetry.
In order to achieve the above object, the solution that this utility model uses is: a kind of crankshaft milling flat fixture,
Including pedestal, pedestal is fixedly connected with prop up for the location supporting crankshaft two end trunnion bracer one, for
Support location bracer two and the pressure assembly down for depressing crankshaft two end trunnion of crank-shaft link neck, fixed
It is provided with the V-type supporting surface of symmetry on the bracer one of position, relative V-type supporting surface is fixedly connected with cushion block
One.Lower pressure assembly includes connecting rod and the drive division of drive connection bar, is provided with briquetting below connecting rod.
It is fixedly connected with cushion block two on the bracer two of location.
Preferably, the lower surface of briquetting is provided for positioning the location cambered surface of main bearing journal.
Preferably, connecting rod being provided with link slot, briquetting upper end is arranged in link slot, briquetting be connected
Groove is connected by connecting shaft.
Preferably, the upper surface of cushion block two is set to level.
Preferably, drive division is set to oil cylinder.
The beneficial effects of the utility model are, this fixture eliminates dividing head, and it is certain that two groups of locating pieces prop up bracer
The trunnion of position crankshaft two end, trunnion is fixed by lower pressure assembly, and location bracer two determines bent axle
The height of connecting rod neck so that the trunnion axis of bent axle and connecting rod neck axis are in sustained height, so that it is determined that
The milling position of bent axle microcephaly, milling again after bent axle spins upside down 180 °, thus improves the right of flat
Title degree, convenient mounting and clamping, and improve clamping quality.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described:
With reference to Fig. 1-Fig. 4, this utility model provides a kind of crankshaft milling flat fixture, including pedestal 10, pedestal
It is fixedly connected with on 10 and props up bracer 1 for the location supporting crankshaft two end trunnion, for supporting bent axle even
Location bracer 2 31 and the pressure assembly 40 down for depressing crankshaft two end trunnion of bar neck 52, location
Prop up the V-type supporting surface 22 being provided with symmetry on bracer 1, the company of fixing on relative V-type supporting surface 22
It is connected to cushion block 1.Lower pressure assembly 40 includes the drive division 42 of connecting rod 41 and drive connection bar 41,
Drive division 42 is set to oil cylinder.Being provided with briquetting 43 below connecting rod 41, the lower surface of briquetting 43 is arranged
For the location cambered surface 431 for positioning main bearing journal 51；Link slot 44 it is provided with, pressure in connecting rod 41
Block 43 upper end is arranged in link slot 44, and briquetting 43 is connected by connecting shaft 45 with link slot 44.Fixed
Being fixedly connected with cushion block 2 32 on the bracer 2 31 of position, the upper surface of cushion block 2 32 is set to level.
During the use of this fixture, two groups of locating pieces prop up the trunnion of bracer certain position crankshaft two end, under
Trunnion is fixed by pressure assembly 40, and location bracer 2 31 determines the height of the connecting rod neck of bent axle, makes
Trunnion axis and the connecting rod neck axis of bent axle be in sustained height, so that it is determined that the milling of bent axle microcephaly
Position, milling again after bent axle is spun upside down 180 °, thus improve the symmetry of flat, this fixture is not only
Eliminate dividing head, simplify clamp structure so that convenient mounting and clamping, and improve clamping quality.
