Abstract
The present invention provides a kind of high-accuracy oil pump connectors, section is rounded, including hollow shell, the inner walls assume a " convex " shape, the housing exterior walls decline in ladder from the opening of one end to waist and form an annular flange in waist, the opening of the shell other end is fixedly connected with the hollow pipe being made by aluminium oxide, the hollow pipe rough surface.The surface roughness of hollow pipe superelevation of the invention is linked without accessory, generates frictional force with its roughness, it is only necessary to be bonded together it firmly with contact surface with medium, connection is simple, sound construction.
Description
Technical field
The present invention relates to precision component fields, more particularly to a kind of high-accuracy oil pump connector.
Background technique
Oil pump is a kind of not only light but also compact pump, there is in-line arrangement, distribution formula and monomer-type three categories.Oil pump wants dynamic
Source could operate, and the camshaft of its lower part is driven by engine crankshaft gear.Existing high-accuracy oil pump often with contact
Bonding is not secured enough, easily damages.
Summary of the invention
Based on this, it is necessary to a kind of high-accuracy oil pump connector is provided, to overcome the above problem.
A kind of high-accuracy oil pump connector, section is rounded, and including hollow shell, the inner walls are in " convex "
Shape, the housing exterior walls decline in ladder from the opening of one end to waist and form an annular flange, the shell in waist
The opening of the other end is fixedly connected with the hollow pipe being made by aluminium oxide, the hollow pipe rough surface.
Further, it is opened up close to shell nozzle side there are five screw hole on the flange.
Further, wherein four two one group of screw holes are divided into two groups, two groups of screw holes are diametrically symmetrical arranged,
Another screw hole is set in the middle part of two groups of screw holes.
Further, the outer wall below the flange with shell lower end seamlessly transits.
The beneficial effects of the present invention are: the surface roughness of hollow pipe superelevation, links without accessory, generated with its roughness
Frictional force, it is only necessary to be bonded together it firmly with contact surface with medium.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the high-accuracy oil pump connector of the present invention；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the bottom view of Fig. 1；
In figure, 1- shell, 2- flange, 3- hollow pipe, 4- screw hole.
Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
A kind of high-accuracy oil pump connector referring to FIG. 1-2, section is rounded, including hollow shell 1, the shell
1 inner wall of body assumes a " convex " shape, and 1 outer wall of shell declines in ladder from the opening of one end to waist and forms a ring-type in waist
Flange 2, the opening of 1 other end of shell are fixedly connected with the hollow pipe 3 being made by aluminium oxide, 3 table of hollow pipe
Face is coarse.
Further, it is opened up close to the side that is open of shell 1 there are five screw hole 4 on the flange 2.
Further, wherein four 4 two one group of screw hole is divided into two groups, two groups of screw holes 4 are diametrically symmetrical arranged, separately
One screw hole 4 is set in the middle part of two groups of screw holes.
Further, 2 lower section of flange and the outer wall of 1 lower end of shell seamlessly transit.
Above-mentioned high-accuracy oil pump connector, the surface roughness of 3 superelevation of hollow pipe are linked without accessory, coarse with its
Degree generates frictional force, it is only necessary to be bonded together it firmly with contact surface with medium, easy to connect, sound construction.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
