Description
Technical field:
The invention belongs to jig field, relate to the one gap positioner that disappears, relate in particular to a kind of manually internal expansion type gap that disappears fixedPosition device.
Background technology:
At present, in the jig of available technology adopting workpiece locating hole location, be generally divided into and utilize machining hole location and hairThe two kinds of situations in location, base hole. The former adopts the alignment pin of a fixed dimension as setting element, and inner hole of workpiece is pacifiedBe contained on the cylindrical of alignment pin and coordinate and position with it. But this kind of situation is due to necessary between inner hole of workpiece and alignment pinHave certain gap, so cannot realize gapless location, position error always can cause to a certain degree the precision of processingImpact. The latter adopts unsteady taper bolt as setting element, and workpiece blank endoporus is arranged on to taper boltOn cylindrical, coordinate and position with it. But this kind of situation, because the surface of blank hole is uneven, is difficult to and taper bolt cylindricalRealize preferably and coordinating, so location situation is poor. Because position error is very large on the impact of machining accuracy, so, need badlyCan ensure the reliable accurately device for location of workpiece locating hole, to improve the precision of location, and then ensure machining accuracy.
Summary of the invention:
The object of the present invention is to provide a kind of compact conformation, easy to use, dependable performance, can improve workpiece locating hole locationReliability and precision, improve the manual internal expansion type of the Workpiece Machining Accuracy gap positioner that disappears.
Technical scheme of the present invention is: the manually internal expansion type gap positioner that disappears, comprising: clamp body, voussoir fairlead, wedgePiece, leading screw, screw rod limiting cover, flange, spacer, handwheel, outer-hexagonal thin nut, internal expanding pin fairlead, internal expanding pin, steel ball, briquetting,Supporting base, adjusting pad, internal expanding bar, spring stop collar, Compress Spring, internal expanding bar fairlead; Flange is arranged on clamp body, leading screwBe bearing in the endoporus of flange, the cylindrical cooperation of voussoir is arranged in the endoporus of voussoir fairlead, and the cylindrical of voussoir fairlead is joinedClose in the endoporus that is arranged on clamp body, the seam cooperation of internal expanding pin fairlead is arranged in the endoporus of clamp body, internal expanding bar guidingThe cylindrical cooperation of cover is arranged in the endoporus of internal expanding pin fairlead, and the cooperation of internal expanding bar is arranged in the endoporus of internal expanding bar fairlead,The cooperation of internal expanding pin is arranged in the endoporus of internal expanding pin fairlead, and the bottom cooperation of internal expanding pin is arranged on the dovetail groove of voussoir, inRise pin top coordinate be arranged on the inclined-plane of internal expanding bar.
The rear portion of leading screw is set with spacer successively, handwheel, and outer-hexagonal thin nut, screw rod limiting cover is installed at the middle part of leading screw, silkThe front threads cooperation of thick stick is arranged on the internal thread of voussoir.
The cooperation of spring stop collar is arranged in the endoporus of internal expanding pin fairlead; On internal expanding bar, be set with Compress Spring, internal expandingThe right part of bar is installed adjusting pad, supporting base successively.
Briquetting on supporting base is fitted on steel ball.
The present invention can reach following beneficial effect after adopting technique scheme: this novel manual internal expansion type disappears gap calmlyPosition device, compact conformation, easy to use, dependable performance, can improve workpiece locating hole reliability of positioning and precision, improves workpieceMachining accuracy can ensure workpiece locating hole reliably accurately location, to improve the precision of location, so improve machining accuracy.
Brief description of the drawings:
Fig. 1 is the disappear main TV structure schematic diagram of gap positioner of the manual internal expansion type of the present invention.
Fig. 2 is the disappear A-A cross-sectional view of gap positioner of the manual internal expansion type of the present invention.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention will be further described. As depicted in figs. 1 and 2: the manually internal expansion type gap positioner that disappears,Comprise: clamp body 1, voussoir fairlead 2, voussoir 3, leading screw 4, screw rod limiting cover 5, flange 6, spacer 7, handwheel 8, the thin spiral shell of outer-hexagonalMother 9, internal expanding pin fairlead 10, internal expanding pin 11, steel ball 12, briquetting 13, supporting base 14, adjusting pad 15, internal expanding bar 16, spring is spacingCover 17, Compress Spring 18, internal expanding bar fairlead 19.
Flange 6 is arranged on clamp body 1, and the middle part of leading screw 4 is bearing on the endoporus of flange 6, and the rear portion of leading screw 4 is overlapped successivelyFill spacer 7, handwheel 8, outer-hexagonal thin nut 9, screw rod limiting cover 5 is arranged on the middle part of leading screw 4, and the front threads of leading screw 4 is joinedClose on the internal thread that is arranged on voussoir 3, the cylindrical cooperation of voussoir 3 is arranged in the endoporus of voussoir fairlead 2, voussoir fairlead 2Cylindrical coordinate and be arranged in the endoporus of clamp body 1, the seam of internal expanding pin fairlead 10 coordinates the endoporus that is arranged on clamp body 1In, the cylindrical cooperation of internal expanding bar fairlead 19 is arranged in the endoporus of internal expanding pin fairlead 10, in 16 cooperations of internal expanding bar are arranged onRise in the endoporus of bar fairlead 19, internal expanding pin 11 coordinates and is arranged in the endoporus of internal expanding pin fairlead 10, the bottom of internal expanding pin 11Coordinate and be arranged on the dovetail groove of voussoir 3, the top cooperation of internal expanding pin 11 is arranged on the inclined-plane of internal expanding bar 16.
