The content of the invention
The purpose of this utility model is to provide a kind of oil pump body eccentric fixture, solves to be directed in the prior art with inclined
The lubricating oil pump of chambers of the heart body, needs two different fixture substeps to be fastened, cumbersome, efficiency low technology when being machined out
Problem.
In order to solve the above-mentioned technical problem the utility model, adopts the following technical scheme that：
A kind of oil pump body eccentric fixture, including chuck, base and caging bolt, the chuck pass through eccentric shaft with base
Connection, eccentric shaft is divided into two sections, wherein one section is connected with chuck, another section is connected with base rotation, and one section of connect base
Set through base；The chuck is radially to offer in three necks, neck to be provided with claw on circle, chuck；Institute
State and screwed hole is offered on chuck, waist-shaped hole corresponding with screwed hole is offered on base, caging bolt passes through screwed hole and waist
Type hole is set；Manual eccentric rotation axis, chuck rotates together with eccentric shaft, after turning an angle, and fastening caging bolt makes
Chuck and base are relatively fixed.
Oil pump body eccentric setting has two circular cylindrical cavities, respectively cavity A, cavity B, to the oil pump body cavity inner surface
During working process, three claws are first passed through to prow oil pump body is fastened on chuck, then unclamp caging bolt, rotate inclined
Heart axle, makes machine oil body cavity body A axis and the axis collinear of bite rotating shaft, then fastens caging bolt, it is ensured that chuck and bottom
Seat is relatively fixed, and is being started lathe, is being processed, and is treated after the completion of the manufacturing procedure, is stopped lathe, unclamps caging bolt, again
Eccentric rotation axis, because offering waist-shaped hole on base, then bolt is slided along waist-shaped hole during eccentric rotation axis, makes lubricating oil pump body cavity
Body B axis and the axis collinear of bite rotating shaft, then fasten caging bolt, it is ensured that chuck is relatively fixed with base, are opening
Motivation bed, is processed to cavity B inner surface.Fixture, extra bed need not be changed, simple to operate, efficiency high is once clamped
The inner surface working process of two eccentric cavitys can be carried out realizing.
Further improve, three necks are distributed on chuck, be easy to accommodate oil pump body.
Further improve, the screwed hole, waist-shaped hole and caging bolt are two, the center of two screwed holes and chuck
Center three point on a straight line, improve fastening effect.
Further improve, the relative surface of three claws is arcwall face, is easy to fit with the side of oil pump body, protect
Card workpiece is fixed with chuck, prevents that workpiece shifts and influences machining accuracy in process.
Further improve, one end of the eccentric shaft through base is provided with operation spanner, is easy to eccentric rotation axis, save
Power.
Compared with prior art, the beneficial effects of the utility model are：
By setting oil pump body eccentric fixture, there are two circular cylindrical cavities to be machined out to oil pump body eccentric setting
When, without changing fixture, extra bed, simple to operate, efficiency high, once clamping can carry out realizing the interior of two eccentric cavitys
Surface Machining processing.

Fig. 2 is the structural representation of eccentric shaft.
Fig. 3 is Fig. 2 left view.
Fig. 4 is the structural representation of oil pump body.
Embodiment
To make the purpose of this utility model and technical scheme clearer, below in conjunction with the utility model embodiment to this
The technical scheme of utility model is clearly and completely described.
As Figure 1-4, a kind of oil pump body eccentric fixture, including chuck 2, base 1 and caging bolt 5, the chuck 2
It is connected with base 1 by eccentric shaft 3, eccentric shaft is divided into two sections, is first paragraph 31 and second segment 32, wherein first paragraph 31 and chuck
2 are connected, and second segment 32 and base 1 are rotated and be connected, and one section of connect base 1 runs through base setting；The chuck 2 is circle,
Radially offered on chuck 2 in three necks, neck and be provided with claw 4；Screwed hole, base 1 are offered on the chuck 2
On offer waist-shaped hole corresponding with screwed hole, caging bolt 5 is set through screwed hole and waist-shaped hole；Manual eccentric rotation axis 3,
Chuck 2 rotates together with eccentric shaft 3, after turning an angle, and fastening caging bolt 5 is relatively fixed chuck 2 and base 1.
Oil pump body eccentric setting has two circular cylindrical cavities, as shown in figure 4, respectively cavity A6, cavity B7, to the oil pump
When Surface Machining is handled in body cavity body, three claws are first passed through to prow oil pump body is fastened on chuck, then unclamp limit
Position bolt, eccentric rotation axis make machine oil body cavity body A axis and the axis collinear of bite rotating shaft, then fasten caging bolt,
Ensure that chuck is relatively fixed with base, starting lathe, be processed, treat after the completion of the manufacturing procedure, stop lathe, unclamp limit
