Described movable semicircle covering device includes riser 4, positioning sleeve 5, handle 8, movable semicircle set 9 and bulb spacer pin 11, Described movable semicircle set 9 includes Step Shaft and is opened in the semicircle orifice of the big end of Step Shaft, and semicircle orifice axis is perpendicular to Step Shaft Axis, the external cylindrical surface of the big end of Step Shaft is provided with guiding rectangular channel, and the bottom land guiding rectangular channel is provided with and bulb spacer pin 11 Suitable pit;Described riser 4 is fixed on base 1, and riser 4 center is provided with the hole being parallel to base 1;Described positioning sleeve 5 One end is vertically embedded in the hole of riser 4, and the other end has and the centre bore of Step Shaft small end external cylindrical surface matched in clearance, intermediate ends Face is fixed on riser 4;Described movable semicircle set 9 runs through positioning sleeve 5, and movable semicircle overlaps on semicircle orifice and the workpiece 18 of 9 one end Boss suitable, the small end external cylindrical surface of described Step Shaft is fixed with handle 8, the width of described handle 8 more than location The aperture of centre bore on set 5;Described bulb spacer pin 11 is perpendicular to the direction of base 1 and embeds in riser 4, bulb spacer pin 11 The guiding rectangular channel that one end puts with movable semicircle is suitable, and the other end has been sequentially placed compression spring 13 and flat head screw 12, the upper surface of flat head screw 12 is fixed on riser 4;Described movable semicircle covering device limits workpiece 18 around apotting spindle 20 A rotary freedom, limit the six-freedom degree of workpiece 18 altogether, meet workpiece 18 uniform through hole 19 processing technology want Ask.
Described clamping device includes open washer 14, studs 15 and binding nut 16, the one of described studs 15 End is perpendicularly fixed at the end face of apotting spindle 20;Described open washer 14 is placed on workpiece 18 through the other end of studs 15 On, described binding nut 16 is tightened against the other end of studs 15, and the external diameter of binding nut 16 is opened more than open washer 14 Mouth width;Using spanner to realize binding nut 16 to the clamping of workpiece 18 and to unclamp, the hatch frame of open washer 14 contracts significantly The impulse stroke that short binding nut 16 clamps and unclamps, it is achieved the quick despatch of workpiece 18.
For one of four uniform boss that the semicircle orifice making movable semicircle overlap 9 one end can quickly block on workpiece 18 External cylindrical surface, meanwhile, in order to make movable semicircle set 9 can realize mobile faster, described movable semicircle covering device also includes bullet Spring 6, described spring 6 is positioned at the space that Step Shaft is formed with positioning sleeve 5, and is enclosed within the small end external cylindrical surface of Step Shaft.
For more firm being fixed on base 1 in the lower end making apotting spindle 20, described base 1 is provided with cylindrical groove, The lower end of described apotting spindle 20 is stuck in cylindrical groove and is anchored on base 1 by soket head cap screw III 21;Interior hexagonal spiral shell Follow closely III 21 have three and be anchored on base 1 by apotting spindle 20 below from base 1.
For more firm being fixed on apotting spindle 20 in the lower end making studs 15, described clamping device also includes solid Determining nut 17, the lower end of studs 15 is anchored on apotting spindle 20 with studs 15 by threaded adapter by fixing nut 17 End face.
In order to ensure assembly precision, the middle end face of described positioning sleeve 5 is fixed on riser 4 by soket head cap screw II 10 On;Described handle 8 passes through pin II 7 fixed cover on the small end external cylindrical surface of Step Shaft;Described riser 4 is by pin I 2 and interior Hex screw I 3 is fixed on base 1.
The plane distribution of the uniform through hole of working position 19, positioner and the clamping device of workpiece 18 is as shown in Figure 1.When When the size of a range of workpiece 18 changes, it is only necessary to change apotting spindle 20, open washer 14 and movable semicircle set 9, locating and machining and the clamping of the series uniform through hole of ring flange can be realized.This fixture is by base 1 with through base 1 two ends ear Studs and the fixing nut of seat 22 are fixed on three shaft vertical machining center workbench.
Before processing, first the positioner assembled is positioned on vertical machining centre workbench, by studs one End load onto T-nut and load on workbench T-slot in, other end through base 1 two ends ear mount 22 and by fix Base 1 pretension on workbench, is carried out centering with the leading flank of base 1 to fixture, uses spanner dextrorotation to tighten fixing by nut Nut secures fixtures on workbench.Position external cylindrical surface with the upper end of apotting spindle 20 and carry out X, Y-axis center to cutter, with fixed The shoulder face, location of position mandrel 20 carries out Z coordinate axle to cutter, determines the benchmark zero point that tool sharpening moves.
Then, movable semicircle set 9 is made to be moved to the left (away from the direction of workpiece 18), bulb spacer pin 11 with pulling handle 8 Snap in the bottom land pit guiding rectangular channel owing to the active force of compression spring 13 stretches out so that movable semicircle set 9 is by bulb Spacer pin 11 is spacing, release handle 8, and movable semicircle set 9 will not move again;Again workpiece 18 is put on apotting spindle 20, and make Workpiece 18 is processed the boss external cylindrical surface approximation of through hole 19 and is aligned the semicircle orifice of movable semicircle set 9, then with hand push handle 8, bulb Spacer pin 11 is retracted, and movable semicircle set 9 centering under the effect of spring 6 bounce snaps in outside the boss that through hole 19 processed by workpiece 18 The face of cylinder, thus complete being properly positioned of workpiece 18.Open washer 14 is placed on workpiece 18 through studs 15, uses The spanner binding nut 16 that turns clockwise compresses open washer 14, thus realizes the Quick-clamped of workpiece 18, and then keeps flange Dish will not loosen along with the course of processing, and then guarantees its invariant position, thus ensures to process the machining accuracy of through hole 19.
Finally, vertical machining centre runs the numerical control program of the uniform through hole of ring flange, is automatically performed drill centers and through hole Processing.After process finishing, unclamp open washer 14, and opening by open washer 14 with spanner rotating clamp counterclockwise jack panel 16 Mouth structure quickly takes off open washer 14;Again with pulling handle 8, (away from the direction of workpiece 18) in handle 8 motor process to the left, Bulb spacer pin 11 snaps in the pit bottom movable semicircle set 9 guiding rectangular channel due to the effect of compression spring 13 elastic force, Movable semicircle set 9 will not move, such that it is able to taken off by workpiece 18, it is achieved the quick-release of workpiece 18 again.
