Specific implementation mode

For a better understanding and implementation, being further described below in conjunction with the accompanying drawings to the utility model：A kind of axis pin diameter Universal fixturing is can adjust to hole drilling, flat key 15 is mounted on inside the keyway of pedestal 1, two pieces V-block fulcrum bearing 14 is installed On pedestal 1, keyway coordinates with flat key 15, and V-block fulcrum bearing 14 is fixed on pedestal 1 with screw and T-nut 18.With Screw by longitudinal T-type guide rail 34 be mounted on V-block fulcrum bearing 14 on, by V-block I 7, V-block II 10 respectively with right-handed nut 8, Left-handed nut 11 is installed together, then right-handed nut 8, left-handed nut 11 are screwed in respectively on longitudinal leadscrew 9, meanwhile, dextrorotation spiral shell Mother 8, left-handed nut 11 are mounted on longitudinal T-type guide rail 34, and longitudinal leadscrew bearing 12 on longitudinal leadscrew 9 and is fixed on V-type In block fulcrum bearing 14, by longitudinally adjusted handwheel 13 on longitudinal leadscrew 9, longitudinally adjusted handwheel 13, V-block I 7, V-block are rotated Flexible, fluent phenomenon is answered in II 10 movements.

The mobile drill jig of installation：Lateral T-type guide rail 27 is fixed on pedestal 1 with screw, transverse shifting nut 25 is screwed in In horizontal leading screw 3, bearing 4, horizontal leading screw tail bearing 2 are attached separately to 3 both ends of horizontal leading screw, then are screwed before horizontal leading screw On pedestal 1, mobile drill jig rear support 24 is mounted in transverse shifting nut 25, drill jig front support 32 is mounted on pedestal 1 On, screw wouldn't be fixed with T-nut 18, and Quick-change drill bush 28 is mounted on bushing plate 22, be propped up after bushing plate 22 and mobile drill jig It is connected, is connected with pin shaft II 31 between spherical surface eyelet bolt 30 and drill jig front support 32, star grip knob with axis pin I 23 between holding 24 29 are screwed on spherical surface eyelet bolt 30, and push down bushing plate 22.By graduated scale 21 on pedestal 1.Handwheel 5 will be laterally adjusted In horizontal leading screw 3, rotation laterally adjusts handwheel 5, and flexible, fluent phenomenon is answered in the movement of transverse shifting nut 25.Tighten spiral shell Nail fixes drill jig front support 32 with T-nut 18, while lockking transverse shifting nut 25 with holding screw 26.

The fixed drill jig of installation：Fixed drill jig rear support 33 is mounted on pedestal 1, fixed drill jig rear support 33 with it is another Bushing plate 22 connects, and bushing plate 22 is equipped with Quick-change drill bush 28, and bushing plate 22 passes through spherical surface eyelet bolt 30 and drill jig front support 32 connections, and push down bushing plate 22.Axially position holder 19 is mounted in fixed drill jig rear support 33, axially position screw 20 are mounted on axially position holder 19, are lockked with nut.

17 lower end of screw rod is screwed into T-nut 18, upper end installation pressing plate 16 is protected simultaneously with 16 position of nut fixation clip Card pressing plate 16 can rotate on screw rod 17.16 another end opening of pressing plate is to just another screw rod 17.

When 6 length of workpiece difference, radial hole site difference, it is necessary to adjust axially position position and the drill jig of workpiece 6 Position, method of adjustment is as follows：

Nut is unclamped, axial positioning screw 20 is rotated, makes 6 left end radial hole of workpiece to the Quick-change drill bush on just fixed drill jig 28 endoporus lock axially position screw 20 with nut.

It is to be oriented to key 15, unclamps screw and T-nut 18, V-block fulcrum bearing 14 can moves left and right on pedestal 1.

Screw and T-nut 18 are unclamped, holding screw 26 is unclamped, rotation laterally adjusts handwheel 5, and horizontal leading screw 3 rotates band Dynamic transverse shifting nut 25 is moved left and right with mobile drill jig rear support 24, drill jig front support 32, bushing plate 22, to make fast replacing drill 28 endoporus are covered to 6 right end radial hole of positive workpiece.It tightens screw again to fix drill jig front support 32 with T-nut 18, while with tightly Determine screw 26 and locks travelling nut 25.

Screw and T-nut 18 are unclamped, moves left and right screw rod 17, pressing plate 16, thus it is possible to vary the position of workpiece pressing 6.

When 6 diameter difference of workpiece, it is necessary to adjust the radial positioning position of workpiece 6, method of adjustment is as follows：

When 6 diameter of workpiece reduces, longitudinally adjusted handwheel 13, longitudinal leadscrew 9 drive right-handed nut rotationally clockwise 8, left-handed nut 11 moves towards, and distance reduces between V-block I 7 and V-block II 10, is suitable for the smaller workpiece 6 of diameter.When When 6 diameter of workpiece increases, longitudinally adjusted handwheel 13 is rotated in an anti-clockwise direction, longitudinal leadscrew 9 drives right-handed nut 8, left-handed nut 11 reverse movements, distance increases between V-block I 7 and V-block II 10, suitable for the workpiece 6 being relatively large in diameter.

The course of work：

1. according to 6 diameter of workpiece, length, radial hole distance, by axially position screw 20, mobile drill jig Quick-change drill bush 28, V Type block I 7, II 10 position of V-block are adjusted.

2. workpiece 6 is placed on V-block I 7, above V-block II 10, left end rotates pressing plate 16 against axially position screw 20, 16 another end opening of pressing plate tightens the nut on screw rod 17, clamping platen 16, to workpiece pressing 6 to just another screw rod 17.Turn Dynamic bushing plate 22 is at horizontal position, and rotation spherical eyelet bolt 30 is at upright position, and is located at bushing plate 22 In open slot, star grip knob 29 is tightened, compresses bushing plate 22.

3. after completing the positioning to workpiece 6 with work is compressed, so that it may to drill to workpiece 6.

4. after completing drilling, unclamping the nut on screw rod 17, pressing plate 16 is rotated, it is made to leave 6 top of workpiece.Unclamp star Handle 29, rotation spherical eyelet bolt 30 disengage it from bushing plate 22, then are rotated up bushing plate 22, are at vertical position It sets, removes workpiece 6, the radial hole drilling work of workpiece 6 just completes.

Using the fixture, reduce tooling quantity, need not frequently replace tooling, it is only necessary to simple adjustment, so that it may to add The different workpiece of work diameter, length, saves the time, improves production efficiency.
