Connect screw drilling accessory to fix with crankshaft end axle journal.
First bent axle fixing hole K is loaded at crankshaft end axle journal and pretension during use.Then bent axle is placed on and is debugged
Fixture in suitable position clamp, make circumferentially positioned plate around crankshaft center line rotation crankshaft end-face drilling connecting screw hole accessory
Suitable position is gone to, and rotating pinching screw 2 makes crankshaft end-face drilling connecting screw hole accessory one is fixed on crankshaft end axle journal
Rise, start processing.
The crankshaft end-face drilling connecting screw hole accessory of this structure is provided with circumferential slot 13 due to bushing plate middle part, circumferential
Axial groove 12 is provided with front side of groove, bent axle fixing hole K is easily deformed during this hatch frame use, affects crankshaft end-face connection
Screw drilling accessory loads at crankshaft end axle journal, therefore service life is short；Deform in this hatch frame clamping process random
Rule, affects crankshaft end-face connecting screw hole positional precision after processing；Additionally, this kind of clamping structure employs pinching screw, spiral shell is clamped
By bushing plate come the cervical region of fixed crankshaft, clamping force is acted in the rectilinear direction of pinching screw nail, is a kind of linear type folder
Tightly, and with cumulative errors, therefore, the structure precision is relatively low.
Utility model content
For improve machining accuracy, it is ensured that processing dimension it is accurate, the purpose of this utility model is to provide a kind of positioning precision
Height, using the fixed form that face pressure is tight, deforms less drilling accessory, and concrete technical scheme is as follows：
Crankshaft end-face drilling connecting screw hole accessory, including bushing plate, the side of the bushing plate are fixed with circumferentially positioned plate,
The bushing plate is a cylindrical diskware, in bushing plate middle part machining crankshafts fixing hole, bent axle fixing hole and crankshaft end
Portion's journal size cooperates, and one group of drill bushing installing hole is processed on the position concentric with bent axle fixing hole, and drill bushing is arranged on described
Drill bushing installing hole in, drill bushing endoporus and drill bit coordinate；Bushing plate opposite side arranges clamp system installing hole, the clamp system
Positioning sleeve is housed above installing hole, gripping sleeve is housed below, unthreaded hole, gripping sleeve middle setting screw thread in the middle of positioning sleeve, is drilled with
Spring is housed in the middle of hole, positioning sleeve and gripping sleeve, pinching screw is passed through from the unthreaded hole of positioning sleeve above, by middle bullet
Spring, screws in following gripping sleeve screwed hole；Clamp system installing hole is intersected with bent axle fixing hole；Equipped with guiding spiral shell before bushing plate
Nail, the axis of guide of guider screw front end is coordinated with the locating slot of positioning sleeve and gripping sleeve realizes that positioning sleeve and gripping sleeve are movable
During do not rotate；The locating surface of the locating surface and gripping sleeve of positioning sleeve and crankshaft end axle in pinching screw clamping process
Neck is contacted.
To ensure the homogeneity of size, after the pre- allowance of bent axle fixing hole is machined, clamp system installing hole is reprocessed, so
Coordinate in clamp system installing hole afterwards and a mandrel is installed, then complete machining crankshafts fixing hole, mandrel is taken out by drawing
Positioning sleeve and gripping sleeve are processed into, to ensure that the locating surface of positioning sleeve, the locating surface of gripping sleeve and clamp system install bore dia
It is equivalently-sized.
This utility model simple structure, manufacture are easy, and using easy to operate, long service life, machining accuracy is high.

Specific embodiment
This utility model is illustrated below in conjunction with the accompanying drawings, and as shown in Fig. 1-Fig. 9, this utility model includes bushing plate 4, institute
The side for stating bushing plate 4 is fixed with circumferentially positioned plate 1, and the bushing plate 4 is a cylindrical diskware, in 4 pars intermedia of bushing plate
Position machining crankshafts fixing hole K, bent axle fixing hole K are cooperated with crankshaft end journal size, the position concentric with bent axle fixing hole K
One group of drill bushing installing hole of processing is put, drill bushing 3 is arranged in described drill bushing installing hole, and 3 endoporus of drill bushing is coordinated with drill bit；Drill jig
4 opposite side of plate arranges clamp system installing hole, positioning sleeve 5 is housed, below equipped with clamping above the clamp system installing hole
Set 6, is drilled with unthreaded hole in the middle of positioning sleeve 5,6 middle setting screwed hole of gripping sleeve is equipped with spring 9, folder in the middle of positioning sleeve and gripping sleeve
Tight screw 2 is passed through from the unthreaded hole of positioning sleeve 5 above, by middle spring 9, screws in following gripping sleeve screwed hole；Folder
Tight mechanism's installing hole is intersected with bent axle fixing hole K；Bushing plate 4 is above equipped with guider screw 7, the axis of guide of 7 front end of guider screw
Coordinate with the locating slot 8 of positioning sleeve and gripping sleeve and realize not rotating during positioning sleeve 5 and gripping sleeve 6 are movable；Folder
The locating surface F of the positioning sleeve and locating surface G of gripping sleeve and crankshaft end journal contact in 2 clamping process of tight screw.
To ensure the homogeneity of size, after the pre- allowances of bent axle fixing hole K are machined, clamp system installing hole is reprocessed,
Then coordinate in clamp system installing hole and a mandrel is installed, then complete machining crankshafts fixing hole K, mandrel taking-up is pressed drawing will
Ask and be processed into positioning sleeve 5 and gripping sleeve 6, to ensure that the locating surface F of positioning sleeve, the locating surface G of gripping sleeve and clamp system are installed
Hole K diameter is equivalently-sized.
When this utility model is used, first bent axle fixing hole K is loaded at crankshaft end axle journal and pretension.Then by bent axle
It is placed in the fixture debugged suitable position and clamps, makes around crankshaft center line rotation crankshaft end-face drilling connecting screw hole accessory
Circumferentially positioned plate goes to suitable position, and rotating pinching screw makes positioning sleeve and gripping sleeve approach to centre, the positioning of positioning sleeve
Face F, the locating surface G of gripping sleeve and crankshaft end axle journal are in close contact to be realized clamping.
This utility model abandoned prior art only by a bent axle fixing hole positioning, and bent axle fixing hole due to
Deformed by the active force and external force of clamp system, and then affect the defect of precision, employ positioning sleeve, the folder of clamp system
Tight set and bent axle fixing hole are positioned jointly, and the positioning sleeve of clamp system, gripping sleeve directly with bent axle neck contacts, reduce
Cumulative error.
