Description
Technical field
Field of fixtures is the utility model is related to, more particularly to a kind of oil pump shaft core pulling flexible jig.
Background technology
Current oil pump shaft core pulling fixture is unadjustable, and a kind of oil pump shaft of model can only be clamped, when needing to press from both sides
It is cumbersome, it is necessary to which fixture is replaced in core pulling when holding the oil pump shaft of different model, reduce work efficiency.And current fixture
It is easy to cause and crushes.Furthermore current fixture is also easy to because oil pump axial end outer rim influences positioning accuracy there are burr.
Utility model content
The purpose of this utility model is that above-mentioned deficiency and defect for the prior art, there is provided a kind of oil pump shaft core pulling can
Fixture is adjusted, to solve the above problems.
The technical problem that the utility model is solved can be realized using following technical scheme：
Oil pump shaft core pulling flexible jig, it is characterised in that including：
Cylinder is clamped, the clamping cylinder includes path cylinder section, conically shaped section and the major diameter cylinder section being coaxially disposed, institute successively
The miner diameter end and bigger diameter end for stating conically shaped section are docked with the path cylinder section, major diameter cylinder section respectively, the conically shaped section and major diameter
The through hole of fuel feeding pump shaft insertion is provided with the middle part of cylinder section, the barrel of conically shaped section and major diameter the cylinder section is circumferentially-spaced to be offered
Some deformation recessing grooves, the inner wall of the path cylinder section are provided with internal thread；
Location mandril, the outer circumferential surface of the location mandril are provided with the external screw thread with the screw-internal thread fit, the positioning
The first end of plug is connected with host, and second end is the positioning surface with oil pump shaft end contact.
In a preferred embodiment of the utility model, there is stud in the middle part of the second end of the location mandril, it is described
Fine setting nut is rotary with stud, the outer end face of the fine setting nut forms the positioning surface with oil pump shaft end contact.
As a result of technical solution as above, the utility model using deform recessing groove so that through hole be adapted to it is a variety of
The oil pump shaft of various outer diameter, and by varying location mandril and the cooperation position of path cylinder section and then different length can also be adapted to
Oil pump shaft, the clamping mating surface of through hole and oil pump shaft is the cylindrical structure to cooperate, will not cause to crush.Furthermore, moreover it is possible to
It is finely adjusted using nut is finely tuned, improves the length accuracy of oil pump shaft, and the size for finely tuning nut is less than outside oil pump axial end
Footpath, there are burr not to interfere with positioning accuracy for oil pump axial end outer rim.
