Abstract
The invention relates to a technology for processing a rotor which is a key part of a composite vane pump, in particular to a process for processing a rotor slot of a vane pump. The processing steps are as follows: 1. drilling a secondary pressure oil hole; 2. milling a rotor slot; 3. pre-cutting a hole slot part of a main pressure oil hole in semi-cut state, and retaining the hole slot main body of the main pressure oil hole; 4. quenching; 5. milling the slot; and 6. after the slot milling, cutting off the hole slot main body. The aim of the invention is to design a process for processing the rotor slot of the vane pump, so as to improve the processing accuracy of the rotor slot. Compared with the prior art, the processing accuracy of the rotor slot is high and reliable; when the process is applied to the composite vane pump, the process has the advantages of improving the volumetric efficiency of the composite vane pump, reducing the noise of the composite vanes, prolonging the service life of the composite vane pump and the like.
Description
Technical field
The present invention relates to the process technology of complex master and auxiliary vane pump vital part rotor, a kind of especially technique for processing rotor slot of vane pump.
Background technology
The structure of complex master and auxiliary vane pump has 12 grooves as shown in Figure 1 on the rotor 4, every groove has a back blades 5, and the outer ring is a cam-shaped stator 6.During work, rotor 4 drives 5 rotations of 12 back blades, blade 5 under pressure, sliding along the cam-shaped inner surface of stator 6 in the top, makes two volume-variation between adjacent blades, produces oil suction and press the process of oil by the both sides oil distribution casing.
During vane pump work, the rotor high-speed rotation, blade is flexible at a high speed in rotor slot, and bear 175 kilograms normal pressure, therefore the machining accuracy of the fit clearance of rotor slot and blade and rotor slot inner surface is one of the principal element in noise, volumetric efficiency and service life of influencing vane pump, the fit clearance that is rotor slot and blade is more little, the machining accuracy of rotor slot inner surface is high more, the above-mentioned performance of product is good more, therefore the processing technology of rotor slot is the critical process of rotor, also is the core manufacturing process of vane pump.
Rotor structure as shown in Figure 2, the processing technology of conventional rotor slot is: bore time pressure oilhole 2 and principal pressure oilhole 1------quenchings---slot grinding that mills rotor slot, or mill rotor slot---inferior pressure oilhole 2 of broaching and principal pressure oilhole 1---quenching---slot grinding etc.The characteristics of above-mentioned processing technology are processing principal pressure oilholes 1 before quenching, Jia Gong shortcoming is like this, because of the existence of principal pressure oilhole 1 is arranged, sheet shape emery wheel is unbalance stress in incision slot grinding process, " cutter relieving " phenomenon appears, the flatness that causes groove is greater than 0.01mm, and the depth of parallelism is greater than 0.012mm (these data are example with the 45V rotor).Such processing method will have to strengthen the fit clearance of rotor slot and blade, and cause the wearing and tearing of blade and rotor slot to be accelerated, and noise strengthens, in let out and increase, phenomenon such as volumetric efficiency is low, and service life is short.
Summary of the invention
The objective of the invention is to design a kind of technique for processing rotor slot of vane pump that improves the rotor slot machining accuracy.
In order to achieve the above object, the present invention adopts following technical solution: a kind of technique for processing rotor slot of vane pump, it is characterized in that its process is followed successively by 1. brill time pressure oilhole, 2. mill rotor slot, 3. the hole slot position of principal pressure oilhole is carried out precuting, be the hemisection state, the hole slot main body that keeps the principal pressure oilhole, 4. quench, 5. 6. slot grinding cuts off the hole slot main body behind the slot grinding again.
Owing to before the quenching slot grinding,, avoided emery wheel unbalance stress in incision slot grinding process by technological measure precut to the principal pressure oilhole, that reserve principal pressure oilhole main body, " cutter relieving " phenomenon appears, and the rotor slot machining accuracy is greatly improved.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is the structure chart of complex master and auxiliary vane pump.
Fig. 2 is a rotor structure figure.
Fig. 3 is a technique for processing rotor slot route schematic diagram.
The specific embodiment
As shown in Figure 3,1. the process of present embodiment is followed successively by bores time pressure oilhole 2,2. mill rotor slot 3,3. the hole slot position of principal pressure oilhole is carried out and precut 7, be the hemisection state, keep the main body 9 of principal pressure oilhole hole slot, cut away vee 8 in advance at the following cut-off part of the principal pressure oilhole hole slot on rotor slot plane simultaneously, 4. quench, 5. 6. slot grinding cuts off principal pressure oilhole hole slot main body 9 behind the slot grinding again.
Reserve because of the principal pressure oilhole hole slot main body before the quenching slot grinding, avoided emery wheel unbalance stress in incision slot grinding process, " cutter relieving " phenomenon occurs, the groove precision is greatly improved.Simultaneously, cut away vee 8 in advance, when principal pressure oilhole hole slot main body 9 is cut off, avoid producing burr, influence plane precision at the limit on rotor slot plane oral area at the following cut-off part of the principal pressure oilhole hole slot on rotor slot plane.With the 45V rotor is example, and the flatness of groove is less than 0.004mm, and the depth of parallelism is less than 0.005mm.
As adopting behind slot grinding line cutting principal pressure oilhole 1 again, although the precision that can guarantee during slot grinding behind the line cutting principal pressure oilhole 1, will produce stress deformation again, the groove precision is made destruction again.Therefore, the processing technology of present embodiment is to improve rotor slot machining accuracy the best, reasonable process technology.
In sum, the present invention compared with prior art has the following advantages:
The rotor slot machining accuracy is high and can access Reliable guarantee; Because the flatness of rotor slot and The parallelism precision height, it is applied on the complex master and auxiliary vane pump, can make the essence that cooperates of rotor slot and blade Degree is improved, and reduces the wearing and tearing between blade and the rotor slot, reduces the noise of complex master and auxiliary vane pump, Let out in the minimizing complex master and auxiliary vane pump, improve the complex master and auxiliary vane pump volumetric efficiency, the prolongation complex master and auxiliary vane pump Service life.
