Description
Technical field
The utility model relates to a kind of screw pump stator tube with uniform wall thickness machining tool, particularly for the Drilling operation instrument of screw pump stator tube with uniform wall thickness locating hole.
Background technology
Equal-wall-thickness stator screw pump has uniform rubber wall thickness, can improve the serviceability of pump well, improves system effectiveness, increases the service life.Stator is the important step in screw pump stator with equal wall thickness manufacture process to mould, existing stator is the locating hole processing some on stator tube wall to mold technique, and bolt is screwed in locating hole, adjust the relative position of core rod in stator tube by adjustment bolt.When processing same wall-thickness stator pipe locating hole, require that locating hole is positioned at height point or the low spot of cross section molded line, due to same wall-thickness stator pipe helical outer surface, be difficult to accurately find high point or low spot, be all the method for being rule by hand dipping at present, machining accuracy is poor, efficiency is low, often because being forbidden positioning hole drilling position, affect screw pump core rod to mould quality, cause screw pump stator rubber core shift.
Summary of the invention
The purpose of this utility model is a kind of screw pump stator tube with uniform wall thickness drill jig of exploitation, processes for screw pump stator tube with uniform wall thickness locating hole.Use drill jig processing stator tube locating hole, can borehole accuracy be significantly improved, increase work efficiency, optimize iso-wall thickness progressive cavity pump core rod positioning process.
For achieving the above object, the technical solution adopted in the utility model is: a kind of screw pump stator tube with uniform wall thickness drill jig, comprise model drilling body, model drilling body inwall has the spirality molded line the same with stator tube outer surface, in the machine tooling drill jig hole, height point position of molded line, and in drill jig hole diamond setting die sleeve; Be two or three modules by Linear cut mode by model drilling body even partition, fixed by die bolt between module, between any two modules, be provided with locating hole.
Preferred above-mentioned drill jig sleeve adopts the mode that removably connects, and the endoporus of drill jig sleeve is greater than outside diameter.
Above-mentioned is three modules by model drilling body even partition, is to cut along the intersection position Linear cut of adjacent two cambered surfaces, obtains three independently modules.
Above-mentioned is two modules by model drilling body even partition, is to cut along two kernel of section position Linear cut, obtains two independently modules.
The beneficial effect of utility model:
1) the utility model screw pump stator tube with uniform wall thickness drill jig, for screw pump stator tube with uniform wall thickness boring provides a kind of new tool and method;
2) the utility model drill jig, can improve the precision of screw pump stator tube with uniform wall thickness boring, improve iso-wall thickness progressive cavity pump core rod to mould quality, can also working (machining) efficiency be improved;
3) the utility model structure is simple, convenient and practical.
