Abstract
The utility model discloses a hydraulic vane pump rotor. The connecting parts are connected by two or more than two welding points. The method comprises the following steps that: firstly, two half rotors are processed, and positioning holes are used to position in the corresponding position; secondly, the butted surface is finely ground and deburred, and then the two half rotors are butted and fixed by a cylindrical pin and a clamp; thirdly, small grooves are processed and welded on the outer edge, and the welding parts are cleaned to remove oil, water and other dirt; and finally, the two halfrotors are butted by the laser welding method, and then the laser-welded rotor is processed. The utility model has the advantages that only the welding parts are melted by the laser welding method, workpieces do not produce high temperature and have no deformation, and the processed workpieces do not need to be cooled to go to the next working procedure, and thereby, the processing time is effectively shortened; the utility model is suitable for the rotor in which a valve core and a flow channel are arranged and other complex structures, effectively prevents the internal components from dislocating, and is also suitable for the welding of the rotor after being fashioned; and the utility model has reliable connecting, non-oxidation, small deformation, high pass rate and low processing cost, and is suitable for mass production.
Description
Technical field
The utility model relates to a kind of hydraulic vane pump rotor.
Background technique
The vane pump fuel-saving technique is the research tendency of hydraulic pressure industry development, yet is subjected to the restriction of vane pump internal structure, makes the fuel-economizing performance be restricted.In its critical component one rotor, drive oil groove and other control units such as spool are installed in order to realize certain model vane pump of oil-saving effect.Processing and spool for the ease of inside tank are installed, and the spy becomes upper and lower two halves rotor with rotor design, processes two halves internal rotor oil groove respectively to requiring, and puts into elements such as spool, welds rotor is coupled together again.Other welding methods all produce a large amount of heats, rotor at high temperature easily causes distortion and stress to concentrate, simultaneously the rotor material performance is changed, original in addition welding method causes temperature distortions such as the blade groove that processes and valve port to cause valve opening dislocation, component abrasion easily for the rotor that element such as spool is arranged in the rotor, can't guarantee that the two halves rotor connects the work of back normal reliable.Expensive, the complex process of existing rotor welding method equipment, and be not suitable for the rotor butt welding that internal rotor has spool and complicated runner.
The model utility content
Purpose: this method is at the upper and lower two halves rotor connection that elements such as spool are arranged in the rotor, two halves rotor joint adopts straight pin to fix, effectively prevent along circumferential staggering, at last carry out laser beam welding in the mode of spot welding, can prevent deformed elements such as spool, and rotor does not produce high temperature, prevents that effectively rotor deformation, accurate positioning, connection are reliable.
The technical solution adopted in the utility model is:
Its inner rotator of the utility model adopts two halves rotor combination up and down, in the two halves rotor runner is arranged, and described two halves rotor uses spot welding to connect.
It is to adopt two or more solder joints to connect that employed spot welding connects.
It is to adopt laser bonding that employed spot welding connects.
The utility model implements to divide following steps.
1, the two halves rotor machines, corresponding position positioning hole location.
2, grind interface, deburring.
3, adopt straight pin and anchor clamps to carry out adorning fixing to the two halves rotor.
4, the little groove of cylindrical processing welding.
5, weld is cleaned, deoil, moisture content, other dirts.
6, insert scolder, adopt the method butt joint two halves rotor of laser beam welding.
7, the rotor after the processing laser beam welding.
The beneficial effect that the utlity model has:
The two halves laser beam welding method of fuel-economizing blade pump rotor of the present utility model has the following advantages:
(1) laser beam welding only makes the fusing of scolder place, and workpiece does not produce high temperature, and workpiece does not have distortion, and needn't cool off after the processing, both can enter subsequent processing, effectively shortens process time.
(2) be applicable to labyrinths such as spool is arranged in the rotor, effectively prevent the inner member dislocation, welding also is suitable for to the rotor after the fine finishing.
(3) promptly be applicable to the butt welding of fuel-economizing blade pump rotor, also be applicable to other vane pump two halves rotor welding.
(4) connect reliable, non-oxidation, be out of shape little, the up-to-standard rate height.
(5) processing cost is low, is applicable to batch process.

Fig. 2 is the structural representation of two halves rotor profiles.
Fig. 3 is the sectional view of welding back rotor.
Embodiment
Embodiment 1: as Figure 1-3, earlier the two halves rotor is machined corresponding position positioning hole location.The correct grinding interface, deburring adopts straight pin and anchor clamps to carry out adorning fixing to the two halves rotor again.The little groove of cylindrical processing welding cleans weld again, deoils, moisture content, other dirts.Adopt the method butt joint two halves rotor of laser beam welding, process the rotor after the laser beam welding then.
Claims (3)
1, a kind of hydraulic vane pump rotor, its inner rotator adopt two halves rotor combination up and down, in the two halves rotor runner are arranged, and it is characterized in that: described two halves rotor uses spot welding to connect.
2, a kind of hydraulic vane pump rotor according to claim 1 is characterized in that: it is to adopt two or more solder joints to connect that employed spot welding connects.
