Description
Technical field
The invention belongs to aero-engine manufacturing fields, and in particular to a kind of to process the fast of multistage tile welding boss stud
Fast location and loading-unloading device and method, it is intended to processing be unevenly distributed, non-directional space cylinder external screw thread when, centering can be positioned
The center of cylinder, the screw die of quick despatch different size complete tapping processing, shorten the process-cycle of part.
Background technology
Have multistage tile in the inner and outer rings of certain aero-engines, and every section of tile be by being unevenly distributed, quantity not
What the space cylinder same, height is different was constituted.It requires space cylinder being processed into MJ strengthened threads in tile design figure, for holding
By larger dead load and dynamic loading.In mechanical processing process, the processing of spatial distribution stud generally use screw die.
By holding screw on die handle, die handle shank is connected screw die with machine tool chief axis.When machine tool chief axis rotates
When, it drives screw die to rotate by die handle, completes tapping processing, but not due to the space cylinder distribution on inner and outer rings tile
Rule so that be difficult to centering center when processing, cause thread size that can not ensure that difficulty of processing is big；If the space cylinder of part
Different size screw threads are processed, the screw die of handling different size need to be shut down, this so that part process cycle is longer.
Invention content
It is an object of the invention to the problems in for the above-mentioned prior art, provide a kind of processing multistage tile welding boss
The quick location and loading-unloading device and method of stud can quickly position the center of centering boss stud, complete its it is externally threaded plus
Work by quick change reducing sleeve, realizes the quick despatch of different size screw die, shortens and add for that need to process the stud of different size
The work period.
To achieve the goals above, the present invention processes the quick location and loading-unloading device use of multistage tile welding boss stud
Technical solution be：Including the die handle that shank is connected with machine tool chief axis, screw die is fixed on die handle, die handle has cylinder
Shape boss positions tapered sleeve with the matched quick change that is equipped with of cylindrical boss, and quick change locating cone, which covers to have, can be set in tile cylinder
Internal taper hole on shape boss stud, screw die are mounted on by quick change reducing sleeve on the cylindrical boss of die handle.
It is offered on the cylindrical boss of the die handle and the matched counterbore of screw die outer circle.
The outer circle of the screw die and the counterbore clearance fit of die handle, by holding screw by the outer circle and die handle of screw die
Counterbore connection, holding screw is not higher by the cylindrical boss circumferential surface of die handle.
It is equipped on the cylindrical boss periphery of the die handle and positions tapered sleeve and the realization of quick change reducing sleeve soon for quick change
The backing pin that quick-mounting unloads, backing pin are the single head stud being connected with cylindrical boss circumferential surface by screw thread.
The stage casing of die handle is machined with annular rounded groove, and annular rounded groove circumferentially offers the oblique of straight-through screw die Working position
Hole.
The front end matching tile boss cylinder chamfer machining of quick change positioning tapered sleeve has internal taper hole, the endoporus and die handle of rear end
Cylindrical boss coordinates, and the depth of endoporus is more than the total of quick change positioning tapered sleeve and the matched part of die handle and screw die overhang
With the waist type groove for installing backing pin is opened up in the outside cylinder of quick change positioning tapered sleeve rear end.
The counterbore of cooperation screw die outer circle is machined in the outside cylinder of quick change reducing sleeve front end；The endoporus of quick change reducing sleeve rear end
It is matched with die handle cylindrical boss, the waist type groove for installing backing pin is opened up in the outside cylinder of quick change reducing sleeve rear end；
It is connect with die handle by the way that backing pin to be mounted in the kidney slot of quick change reducing sleeve, when the die handle that combination quick change positions tapered sleeve is fixed
After the centering part cylindrical center of position, tapered sleeve is positioned by backing pin rapid removal quick change, loads onto the quick change reducing sleeve of installation screw die, into
Row tapping works.
The present invention processes the quick positioning handling method of multistage tile welding boss stud, includes the following steps：
1) installation of compoboard retainer：When it is same specification screw thread to process part stud, make the outer circle and screw die of screw die
The counterbore matching of frame is merged into capable fixation, and the shank of die handle is connected with machine tool chief axis；
2) combination quick change positioning tapered sleeve positions centering post-processing：Quick change positions the outer circle intercolumniation of the endoporus and die handle of tapered sleeve
Gap coordinates, and is connect quick change positioning tapered sleeve with die handle by backing pin；Make the chamfering of quick change positioning tapered sleeve and part space cylinder
Cooperation, quickly the center of positioning and centering column part, determines that the position of connection die handle shank machine tool chief axis, centering determine machine
After bed main spindle's, backing pin is exited from the kidney slot that quick change positions tapered sleeve；Machine tool chief axis drives the plate being mounted on die handle
Tooth completes tapping；
3) combination quick change reducing sleeve completes tapping：When processing part stud is different size screw thread, turned using quick change
Female connector is realized, tapered sleeve is positioned and position centering machine the counterbore of the outer circle of screw die and quick change reducing sleeve with capable fixation, quick change is merged into
After bed main spindle's, quick change positioning tapered sleeve is unloaded, then be mounted in the kidney slot of quick change reducing sleeve by backing pin, by Combined die
