Background technology
Above aero-engine, there is the part of a lot of pins, bolt class, need on the face of cylinder, process lock silk hole, but because aperture is less, be again to process on the face of cylinder, if there is no fixture, processing is just difficult to carry out, because part kind quantity is more, and some part production requirement quantity is less, some part is not just sent fixture processed, and the cost of group's fixture processed is tens times of part.Also have, although group has made special fixture, but may run into aborning fixture censorship, the reasons such as fixture damage or loss or some fixture existence design are reasonable not cause manufacturing schedule to be affected, at this moment just need assembled tool, not only increase employee's workload, also can delay production node; Simultaneously, because general special fixture designs for one certain working procedure, it can only be processed with the part of fixing size, if the workpiece size of last process is overproof, or processing work size strengthens temporarily, former special fixture may not use, and need to reselect fixture, so expends man-hour and becomes a current difficult problem that affects aero-engine production efficiency for process several little locks hole on a small amount of pin and bolt class part in fixture problem.
The patent No. is 201220620868.8 for this reason, the Chinese patent that name is called a kind of modularization fixture for pin and bolt class drilling part discloses a kind of new departure, this scheme has solved above-mentioned problem to a certain extent, but still there are some problems in this scheme in actual production, as in the time that twisting screw rod slides wedge block, wedge block produces friction with the face of cylinder of workpiece sometimes, because the roughness on the face of cylinder of this type of workpiece etc. requires higher, this friction leaves scratch sometimes, thus impact assembling.
Summary of the invention
The problem existing for prior art, the invention provides a kind of fixture for post class drilling part of avoiding abrading workpiece, realization utilizes the function of a sleeve clamp processing various parts, utilize wedge block and inclined-plane to coordinate, upwards hold out against part, wedge block and inclined-plane frictionally are realized self-locking simultaneously.This fixture has two kinds of locate modes, and in drill bushing, the relative part outer centering in the position of machining hole is better, and compression can not crush part.
To achieve these goals, the present invention adopts following technical scheme; A kind of fixture for post class drilling part, comprise base, described base middle part is provided with inclined-plane, and the wedge block corresponding with inclined-plane is set on described inclined-plane, the side shield of wedge block is set in base side, and screw rod one end is flexibly connected with wedge block through side shield; Screw rod is connected with side shield threaded engagement; Supporting plate is set above wedge block, is provided with projection in the side of supporting plate, be provided with the chute matching with the projection of supporting plate on base, supporting plate can move up and down along chute; The locating piece being fixed on base is being set above supporting plate, bottom center's line position at described locating piece arranges V-type groove, the location adjustment bar that can slide along V-type groove is set in V-type groove or on described base, the side on inclined-plane is provided with adjusting block, described adjusting block and base sliding are connected, and regulate block to slide along the fluting direction of V-type groove; In locating piece above V-type groove, drill bushing is set.
Preferably, the angle of inclination on described inclined-plane is not more than 20 degree.
Further preferably, the trip bolt of fastening screw is set on described side shield.
Further preferably, described adjusting block is L-type.
The present invention compared with prior art has following beneficial effect; Avoid workpiece to be scratched, improved production qualification rate, ensure the surface aesthetic of workpiece; The workpiece that dither while avoiding holing causes is loosening, ensures precision and the quality of boring.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail;
As shown in Figure 1, a kind of fixture for post class drilling part, comprise base 1, on base 1, there is an inclined-plane 11, the angle of inclination on inclined-plane 11 is 18 degree, on inclined-plane 11, be provided with the wedge block 2 that can slide along inclined-plane 11, the wedge angle of wedge block 2 is identical with the angle of inclination on inclined-plane 11, the side shield 4 of this wedge block is set in base 1 side, one end that wedge block 2 is pressed close to side shield 4 arranges open slot, and one end of screw rod 3 is stretched in the open slot of wedge block 2 and coordinates with the open slot of wedge block 2 through side shield 4; Described screw rod 3 is interior free to rotate at wedge block 2, and can on inclined-plane 11, slide by push-and-pull wedge block 2; Screw rod 3 is connected with side shield 4 threaded engagement; Wedge block 2 tops are provided with the supporting plate 5 vertically sliding along base 1, are provided with projection 51 in the side of supporting plate 5, are provided with the chute matching with the projection 51 of supporting plate on base 1, and supporting plate 5 can move up and down along chute; Supporting plate 5 tops are provided with locating piece 6, and locating piece 6 is fixed on base 1;
As shown in Figure 2, at bottom center's line position of described locating piece 6, V-type groove 61 is set, the location adjustment bar 8 that can slide along V-type groove in the 1 interior setting of step type groove border, locating piece 6 is provided with the screw for tightening location adjustment bar 8; In locating piece border above V-type groove 61, drill bushing 7 is set.
As shown in Figure 3, on described base 1, the side on inclined-plane 11 is provided with L-type and regulates block 9, regulates block 9 to slide along the fluting direction of V-type groove 61; Regulate block 9 and base 1 to be slidably matched and by screw tightening, regulate the glide direction of block 9 identical with the fluting direction on V-type groove border 1; On side shield 4, be threaded and be useful on the trip bolt 10 of tightening screw rod 3, trip bolt 10 is with swing handle, although the angle of inclination on inclined-plane 11 can make wedge block 2 self-lockings in theory, but can produce dither by coupled columns class part during due to boring, sometimes it is loosening that this vibration can make screw rod 3 produce, thereby cause post class part loosening, precision and the quality of impact boring; By screw rod 3 is carried out to tightening, can avoid screw rod 3 loosening, ensure to clamp firmly.
Below in conjunction with a brief description of the drawings use procedure of the present invention;
Post class part is placed in the V-type groove 61 on locating piece border, with regulating block 9 or location adjustment bar 8 by post class part location, and by screw or screw, adjusting block 9 or location adjustment bar 8 is carried out to tightening; Then pull wedge block 2 by supporting plate 5 jack-up by the rotation of screw rod 3, utilize the threaded engagement effect of screw rod 3 and side shield 4, and utilize trip bolt 10 by fixing screw rod 3, due to wedge block 2 and the frictional force effect on inclined-plane 11 and the fixation of screw rod 3, thereby make post class part fixing between locating piece 6 and supporting plate 5, start to carry out Drilling operation.
The present invention, by install a supporting plate 5 vertically sliding additional above wedge block 2, makes friction between wedge block 2 and supporting plate 5, and supporting plate 5 vertical liftings, can not produce friction with post class part, avoid post class part to be scratched, improved production qualification rate, and ensured the surface aesthetic of workpiece.
