Background technology:
At present, prior art uses in the jig of location, hole, workpiece location, be generally divided into location, utilization processing hole and blank hole positions two kinds of situations.The former is usually and uses the alignment pin of a fixed dimension as setting element, and inner hole of workpiece is arranged on matched on the cylindrical of alignment pin location.But, this kind of situation is owing to must there be certain gap between inner hole of workpiece and alignment pin, so gapless location cannot be realized, the precision of processing always can be caused a certain degree of impact by position error.The latter is usually and uses a taper bolt floated as setting element, and workpiece blank endoporus is arranged on matched on the cylindrical of taper bolt location.But, this kind of situation is uneven due to the surface of blank hole, it is difficult to and taper bolt cylindrical realizes preferably coordinating, so location situation is poor.Owing to position error is very big on the impact of machining accuracy, so, need a kind of device that ensure that hole, workpiece location is reliably accurately positioned badly, to improve the precision of location, and then ensure machining accuracy.
Utility model content:
The purpose of this utility model is to provide a kind of compact conformation, easy to use, dependable performance, it is possible to increase workpiece location hole reliability of positioning and precision, improves the manual internal expansion type of Workpiece Machining Accuracy and disappears gap positioner.
The technical solution of the utility model is: manual internal expansion type disappears gap positioner, including: clamp body, voussoir fairlead, voussoir, leading screw, screw rod limiting set, flange, spacer, handwheel, outer-hexagonal thin nut, internal expanding pin fairlead, internal expanding pin, steel ball, briquetting, bearing, adjusting pad, internal expanding bar, spring retainer set, compression spring, internal expanding bar fairlead；Flange is arranged on clamp body, leading screw is bearing in the endoporus of flange, the cylindrical of voussoir coordinates in the endoporus being arranged on voussoir fairlead, the cylindrical of voussoir fairlead coordinates in the endoporus being arranged on clamp body, the seam of internal expanding pin fairlead coordinates in the endoporus being arranged on clamp body, the cylindrical of internal expanding bar fairlead coordinates in the endoporus being arranged on internal expanding pin fairlead, internal expanding bar coordinates in the endoporus being arranged on internal expanding bar fairlead, internal expanding pin coordinates in the endoporus being arranged on internal expanding pin fairlead, the bottom cooperation of internal expanding pin is arranged on the dovetail groove of voussoir, the top cooperation of internal expanding pin is arranged on the inclined-plane of internal expanding bar.
The rear portion of leading screw is set with spacer, handwheel, outer-hexagonal thin nut, the middle part installation screw rod limiting set of leading screw successively, and the front threads cooperation of leading screw is arranged on the internal thread of voussoir.
Spring retainer set coordinates in the endoporus being arranged on internal expanding pin fairlead；Compression spring, the right part of internal expanding bar mounting and adjusting pad successively, a bearing it is set with on internal expanding bar.
The briquetting propped up in bearing is fitted on steel ball.
The utility model uses and can reach following beneficial effect after technique scheme: this novel manual internal expansion type disappears gap positioner, compact conformation, easy to use, dependable performance, workpiece location hole reliability of positioning and precision can be improved, improve Workpiece Machining Accuracy and ensure that hole, workpiece location positions the most accurately, to improve the precision of location, and then improve machining accuracy.
Accompanying drawing illustrates:
Fig. 1 is that the manual internal expansion type of the utility model disappears the main TV structure schematic diagram of gap positioner.
Fig. 2 is that the manual internal expansion type of the utility model disappears the A-A cross-sectional view of gap positioner.
Detailed description of the invention:
Below in conjunction with the accompanying drawings the utility model is further described.As depicted in figs. 1 and 2: manual internal expansion type disappears gap positioner, including: clamp body 1, voussoir fairlead 2, voussoir 3, leading screw 4, screw rod limiting set 5, flange 6, spacer 7, handwheel 8, outer-hexagonal thin nut 9, internal expanding pin fairlead 10, internal expanding pin 11, steel ball 12, briquetting 13, bearing 14, adjusting pad 15, internal expanding bar 16, spring retainer set 17, compression spring 18, internal expanding bar fairlead 19.
nullFlange 6 is arranged on clamp body 1，The middle part of leading screw 4 is bearing on the endoporus of flange 6，The rear portion of leading screw 4 has been set with spacer 7 successively，Handwheel 8，Outer-hexagonal thin nut 9，Screw rod limiting set 5 is arranged on the middle part of leading screw 4，The front threads cooperation of leading screw 4 is arranged on the internal thread of voussoir 3，The cylindrical of voussoir 3 coordinates in the endoporus being arranged on voussoir fairlead 2，The cylindrical of voussoir fairlead 2 coordinates in the endoporus being arranged on clamp body 1，The seam of internal expanding pin fairlead 10 coordinates in the endoporus being arranged on clamp body 1，The cylindrical of internal expanding bar fairlead 19 coordinates in the endoporus being arranged on internal expanding pin fairlead 10，Internal expanding bar 16 coordinates in the endoporus being arranged on internal expanding bar fairlead 19，Internal expanding pin 11 coordinates in the endoporus being arranged on internal expanding pin fairlead 10，The bottom cooperation of internal expanding pin 11 is 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.Spring retainer set 17 cooperation is arranged in the endoporus of internal expanding pin fairlead 10, and compression spring 18 is sleeved on internal expanding bar 16, the right part of internal expanding bar 16 mounting and adjusting pad 15 successively, a bearing 14, and steel ball 12 is fitted in a bearing 14 by briquetting 13.
