Abstract
The invention provides a cylindrical part inner wall bulge feature back-gouging tool which is used for back gouging of bulge special-shaped features of a cylindrical part so as mount equipment on the inner wall of the cylindrical part and can guarantee processing consistency of parts, subjected to back gouging, of the part, avoid interference between instrument equipment and parts, not subjected to back gouging, of the cylindrical part and guarantee smooth mounting and reliable quality. The cylindrical part inner wall bulge feature back-gouging tool is composed of a connecting screw, a locking nut and a special-shaped self-alignment back gouging electrode, wherein one end of the connecting screw is a polish rod and the other end of the connecting screw is a screw; the polish rod end is connected with a main shaft of an EDM machine tool; the screw end is connected with a screw hole in the special-shaped self-alignment back gouging electrode; and the locking of the connecting screw and the special-shaped self-alignment back gouging electrode is realized through the locking nut. According to the method, back gouging of any bulge feature of the inner wall of the cylindrical part is completed through the EDM machine tool, and in addition, an alignment plane is arranged on the electrode, so that alignment of the electrode and the product is facilitated, accurate back gouging of the bulge features of the inner wall of the cylindrical part is realized, mechanization is realized and quick and accurate grinding is realized.
Description
Technical field
The present invention relates to a kind of back chipping frock, particularly a kind of cylindric part inwall protruding features back chipping frock, for the removal of small space cylindrical inner protruding features surrounding metal surplus, realize without interference fit, particularly the back chipping of the special-shaped protrusion features of the cylindric part inwall of space flight.
Background technology
In space product, cylindric part inwall installs various instrument and equipment, and the feature of machining limit due to cutter fillet, and the boss surrounding surplus of erection unit can not be removed, and affects equipment and instrument and installs.Traditional technique is manual polishing, carries out trial assembly join with trial assembly part, and judge the possibility of formal assembling, labour intensity is large, and polishing precision is uncontrollable, can not meet design requirement completely, realizes the accurate installation requirement of equipment and instrument.
Summary of the invention
The object of the invention is by one cylindric part inwall protruding features back chipping frock, the special-shaped feature back chipping of projection for cylindric part inwall erection unit, ensure the uniformity that part is processed by back chipping position, avoid the interference at instrument and equipment and the non-back chipping position of cylindric part inwall, guarantee smooth, reliable in quality is installed.
Cylindric part inwall protruding features back chipping frock is made up of from centering back chipping electrode connecting screw rod, locking nut and abnormal shape, connecting screw rod one end is polished rod, one end is screw rod, polished end is connected with spark-erosion machine tool main shaft, the screw that screw rod end is suffered from one's own actions on positive electrode with special-shaped back chipping is connected, and realizes connecting screw rod and special-shaped back chipping suffer from one's own actions positive electrode and lock by locking nut.
Abnormal shape is hexahedron from centering back chipping electrode, upper and lower both ends of the surface distance is determined by the length range at back chipping position according to the special-shaped feature of processed cylindric part inwall, one of peripheric surface is plane, the position from centering back chipping electrode and cylindrical shell is determined for centering, two peripheric surfaces be adjacent and this plane orthogonal, for from centering back chipping electrode and processed protruding features centering, all the other one sides are coupled with cylindric part inwall cambered surface, and its lap ensures that processing is not interfered; There is a screwed hole electrode upper surface, be connected with spark-erosion machine tool main shaft by screw rod, have a groove between cambered surface and relative peripheric surface, this groove shape is identical with cylindric part inwall protruding features appearance profile, and between protruding features profile, monolateral distance is 0.1-0.5mm.By this frock, the back chipping of any protrusion features of cylindric part inwall can be completed, guarantee to realize design objective, meet part and assemble smoothly.
Existing back chipping method is for completing the special-shaped feature back chipping of cylindric part inwall by grinding head is manual, polishing workload is large, and the precision of polishing cannot reach design objective requirement, poor reliability, the phenomenon of field polish is needed during frequent appearance assembling, and polishing limit by Material texture, the material grinding efficiencies such as steel drum shape part are low, cannot meet need of production.This method is by the cylindric part inwall back chipping electrode of design, the back chipping of any protrusion features of cylindric part inwall is completed by spark-erosion machine tool, and electrode is designed with centering plane, facilitate electrode and product centering, realize the accurate back chipping of the special-shaped feature of cylindric part inwall, the electrode being applicable to the metal material such as steel, aluminium matter should select red copper electrode, is replaced manual by machinery, realize accurately polishing fast, ensure that research and production is carried out smoothly.

Detailed description of the invention
According to the electrode of the Material selec-tion respective material of part to be processed, such as part to be processed is steel, electrode selects red copper, the shape that special-shaped back chipping suffers from one's own actions positive electrode is designed according to part to be processed inwall protruding features, this electrode is column hexahedron, upper and lower two planes are parallel, surrounding one side is the arc surface identical with cylinder inner surface radian, there are orthogonal two planes for processing centering, working position suggestion arranges suitable machining gap 0.5mm, by electrode assemblie screw rod shaven head end is installed on EDM shaping machine main shaft, cylindric part is placed on spark-erosion machine tool workbench, machine coordinates relation is set up by the orthogonal plane of electrode and cylindric part, the cylindric part center of circle and electrode centers are set to XY zero point (see Fig. 3), using cylindric part upper surface as Z axis zero point, electrode movement is to the coordinate of the processed feature of cylindric part, by spark-erosion machine tool expert system, spark machined parameter (discharging gap is set, roughness, workpiece material and electrode material), namely part processing can be completed, add man-hour, electrode can wear and tear, positive electrode is suffered from one's own actions by changing, the accurate back chipping of cylindric part boss (see Fig. 4) can be realized.
Suppose that workpiece material is steel, electrode material is red copper, electrode and absorption surface gap are set to monolateral 0.15mm, select the parameter of roughness 3.2, by spark-erosion machine tool motion of main shaft by electrode movement to the cylindric any position of part inwall, realize the accurate back chipping of the special-shaped feature in the cylindric any position of part inwall.
