Description
Technical field
The present invention relates to the processing method of vane type motor stator, particularly relate to a kind of mesohigh vane motor bore of stator surface processing technique.
Background technology
Because the pressure oil effect, the vane motor rotor is subjected to unbalanced power and rotates.The output torque of vane motor is relevant with the pressure differential between the discharge capacity of hydraulic motor and the hydraulic motor oil inlet and outlet, its rotating speed is decided by the flow size of input hydraulic pressure motor, can normally start and move after pressure oil feeds in order to ensure vane motor, vane tip is closely contacted with stator inner surface, to guarantee good sealing, therefore at root of blade preloading spring should be set, make between hydraulic motor bore of stator surface and the vane tip excellent contact is arranged, simultaneously, require vane tip and hydraulic motor bore of stator surface that the surface of good crudy is arranged, wherein, because the crudy on hydraulic motor bore of stator surface is difficult to guarantee, the quality of its crudy directly has influence on the quality of whole hydraulic motor, if the dimensional accuracy and the surface finishing precision on hydraulic motor bore of stator surface do not reach requirement, just have seepage in the use between hydraulic motor bore of stator surface and the vane tip, the speed of hydraulic motor and precision all do not reach requirement, use also dangerous, particularly when hoisting heavy, be difficult to guarantee the skidding distance, security incident takes place easily.
Mesohigh vane motor bore of stator surface normally is made up of multi-section circular arc, the bus linearity of its surface finishing degree and multi-section circular arc requires very high, and existing processing technology generally is to adopt the multi-section circular arc rib exterior feature of processing surface of internal cavity earlier with numerical control borer, method with polishing makes the surface reach the degree of polishing again, because the width of vane motor stator is bigger, the numerical control borer boring bar is stretched longly in the process, the numerical control borer boring bar always has small flexural deformation under the effect of cutting force, make the vane motor bore of stator surface configuration that processes have certain tapering, be difficult to guarantee the linearity requirement of mesohigh vane motor bore of stator surface bus; Simultaneously, with the just polishing of boring cutter processing back, though naked eyes look also polishing very of surface, but the lines that boring cutter processing stays can not all flatten, still have more serious seepage between feasible hydraulic motor bore of stator surface in use and the blade tip, influence is normal uses poor safety performance.
Summary of the invention
The purpose of this invention is to provide a kind of mesohigh vane motor bore of stator surface processing technique, adopt the high pressure vane motor stator of this processes, in use seepage is few between mesohigh vane motor bore of stator surface and the blade, and is safe and reliable.
In order to achieve the above object, mesohigh vane motor bore of stator surface processing technique of the present invention is characterized in that:
1., with the multi-section circular arc curve rib exterior feature on numerical control borer processing mesohigh vane motor bore of stator surface, add and stay subsequent handling allowance man-hour;
2., detect mesohigh vane motor bore of stator surface size precision;
3., with numerically control grinder grinding mesohigh vane motor bore of stator surface, boring is added reaches the drawing specification requirement near an end inner cavity size precision of boring cutter man-hour;
4., level straight line with a roller outer round surface and coat mimeograph;
5., the straight line roller that outer round surface is scribbled mimeograph rolls at mesohigh vane motor bore of stator surface stone roller;
6., have the surface to carry out grinding with mimeograph, the end surface of internal cavity near boring cutter during grinding is not processed to mesohigh vane motor bore of stator;
7., detect mesohigh vane motor bore of stator surface size precision, if size does not reach the drawing requirement, repeating step is 4., 5. and 6.;
8., processing is polished on mesohigh vane motor bore of stator surface, make mesohigh vane motor bore of stator surface roughness reach the drawing requirement.
Because mesohigh vane motor bore of stator surface processing technique of the present invention is formerly to make boring processing reach the drawing specification requirement near an end inner cavity size precision of boring cutter, detect by the straight line roller then, again the carrying out that does not reach dimensional accuracy processed repeatedly, reach the drawing specification requirement up to mesohigh vane motor bore of stator surface size precision, mesohigh vane motor bore of stator surface configuration does not have tapering; Simultaneously, carried out grinding again after numerical control borer processing, eliminated the lines that boring cutter processing stays, in use seepage is few between mesohigh vane motor bore of stator surface and the blade, and is safe and reliable; Simultaneously, because the lines that mesohigh vane motor bore of stator surface does not have boring cutter processing to stay, the sealing strip on the blade can not be worn, and prolongs its service life.
Described mesohigh vane motor bore of stator surface processing technique is characterized in that: the straight line roller is the cylinder of a two ends handlebar handle, and cylinder cylindrical bus straightness error is less than 1/1000.
Described mimeograph is dark mimeograph, and dark mimeograph is checked easily attached to mesohigh vane motor bore of stator surface.
Mesohigh vane motor bore of stator surface processing technique of the present invention, adopt the mesohigh vane motor stator of this processes, in use seepage is few between mesohigh vane motor bore of stator surface and the blade, and is safe and reliable.
