Abstract
The utility model discloses a positioning structure of a steering oil pipe and an oil pump interface for an automobile, which comprises a metal joint and a positioning block (positioning piece). The positioning structure is characterized in that the positioning block (positioning piece) is welded on the surface on the outer side of the metal joint. The positioning structure leads the flexibility, the diversity and the reliability of the connection of the metal joint and the oil pump interface to be improved greatly, thereby adapting to wider joint mode and higher design requirements.
Description
Technical field:
The utility model relates to a kind of auto parts and components, specifically is the location structure of a kind of motor turning oil pipe and oil pump interface.
Background technology:
At home, the oil pump structure of vehicle high-pressure oil pipe connection at present is: weld an annular hollow joint at steel tube head, this joint is to be formed by metal machining, utilizes the hollow bolt screwed in place on power steerig pump.This structure has following shortcoming: 1, the oil connector location can't correctly guarantee.2, rigging position and the distance be difficult to control easily make a mistake.3, under long-time abominable service conditions, if bolt looseness, the joint easily axially jumps, and produces oil leakage phenomenon.4, discontinuity, joint surface is easy to wear.
Summary of the invention:
The utility model provides the location structure of a kind of improved motor turning oil pipe and oil pump interface, directly at the hollow joint welding of annular a positioning block (spacer), the position trend of locating piece (spacer) contacts with oil pump and matches, and corresponding design is adopted in different requirements; Solve the orientation problem of oil connector and oil pump, optimized the structure of oil connector, improved the safety performance and the conformability of steering oil pipe system.
The technical solution adopted in the utility model is:
A kind of location structure of motor turning oil pipe oil pump interface comprises oil pipe, oil pump: an annular hollow joint is welded in the oil pipe termination, welds a positioning block on the annular hollow joint, oil pipe and hollow inner nosepiece wall UNICOM.Described locating piece adopts brazing mode to be welded on the annular hollow joint.
Advantage of the present utility model:
The utility model provides the location structure of a kind of improved motor turning oil pipe and oil pump interface, and this structure has several advantages: 1, the locality of accurate in locating oil pipe banjo fitting.2, be easy to assembling, prevent that the workman is because of the carelessness loading error.3, assembling is firm reliable, prevents the stressed generation of the joint displacement that jumps.4, control oil pipe trend guarantees that trend is correct.5, increase stress point, make banjo fitting stressed evenly.This structure has solved above-mentioned relevant issues in the product use.

Fig. 2 is the utility model birds-eye view;
Fig. 3 is a locating piece cross-sectional view of the present utility model;
Fig. 4 is a tubing interface cross-sectional view of the present utility model;
Fig. 5 is other mode structures of locating piece;
Fig. 6 is other mode structures of locating piece;
Fig. 7 is other mode structures of locating piece.
The specific embodiment:
Referring to Fig. 1, Fig. 2:
The connector locating piece structure of automobile oil pipe is made up of metal positioning block 1, metal joint 2.Be welded with a cylindrical locating piece 1 on the metal joint 2, melt by spelter and make metal positioning block 1 and metal joint 2 weld togethers adding weldering place 3.Can be according to the requirement of system design, the angle of control metal positioning block 1 and steel pipe 4 (as Fig. 4).
The structure of locating piece can also be designed to other forms, and as Fig. 5, Fig. 6, Fig. 7, this mainly is that mode is varied according to the design-calculated needs, is suitable for different service conditions.
According to different working environments, design corresponding welding tooling.Joint and locating piece adopt brazing mode, during soldering, after the oil connector mating surfaces cleaned, assemble with joint form, are placed on solder near the joint clearance or directly put into the joint clearance.After joint is heated to the fusion temperature of a little higher than solder with solder, solder will melt and soak into joint surface.Liquid solder will flow along seam and sprawl by capillarity.So dissolved mutually between brazed joint of metal and solder, exchange penetration forms alloy-layer, promptly forms brazed joint after the condensation.The characteristics of soldering are that joint surface is bright and clean, and air-tightness is good, and shape and size are stable, and the tissue and the performance variation of weldment are little, and solder fusing and weldment does not melt can be satisfied the accuracy requirement of oil pipe locating piece.The locating piece welding filler metal adopts spelter, has very high intensity, can satisfy the requirement of oil connector locating piece bearing load.
