Abstract
The utility model relates to field of machining, specifically a kind of fixture suitable for axial workpiece swinging bore hole.Including pedestal, positioning disk, mandrel, fixed supported slab, sliding jacking mechanism；Fixture base is equipped with positioning disk, and positioning disk can rotate on pedestal；Mandrel is equipped between pedestal and positioning disk, mandrel is fixed on by sunk screw on positioning disk, and top is limited by locking nut, and mandrel is the pillar of fixed parts to be processed；Sliding jacking mechanism pushes sliding block to hold out against part in the horizontal direction, prevents part double swerve in process.The utility model proposes fixture mandrel both ends attaching nut to realize the axially position of part, and the horizontal location of part is realized by fixed supported slab and sliding jacking mechanism, the utility model proposes fixture reduce part processing used in the time, improve the machining accuracy and processing efficiency of part, simple in structure, operation and feature easy to use.
Description
Technical field
The utility model relates to field of machining, specifically a kind of to be suitable for axial workpiece swinging bore hole
Fixture.
Background technology
Bore hole is can to expand aperture to having drilled out, having forged or having cast out the further processing in hole, bore hole with cutter, improves essence
Degree reduces surface roughness.Bore hole in the prior art is processed on lathe, boring machine or milling machine, typically to be added
Work parts fixation carries out positioning and clamping on lathe, to part, and Boring can be carried out after positioning datum centering, and for two
Face is required for for the symmetrical holes of processing, can only first be processed one side, then be repositioned again, the post-processing of centering benchmark is another again
Face, the concentricity that such processing method often results in symmetrical holes have deviation, product qualification rate are caused to reduce, and processing cost carries
It is high.
Utility model content
The problem of the technical problems to be solved in the utility model is for background technology provides a kind of suitable for axis
The fixture of class part swinging bore hole.
Technical solution：A kind of fixture suitable for axial workpiece swinging bore hole, including pedestal, positioning disk, mandrel with, it is solid
Determine support plate, sliding jacking mechanism；Positioning disk is connect by fastening screw and eyelet bolt with pedestal, and base center is equipped with " work " word
Type through-hole, mandrel run through pedestal and positioning disk；Mandrel is fixed on by sunk screw on positioning disk, and the bottom end of mandrel is equipped with lock
Tight nut is moved up with limiting mandrel；After parts to be processed is packed into mandrel and centering, the nut that is arranged by mandrel tip with
Compressing component；Base plate through holes are embedded in bushing, and mandrel bottom end is made to be inserted in bushing, form clearance fit, process part in this way and exist
In process, positioning disk and mandrel can flexible rotating, reduction frictions on pedestal；Fixed supported slab is mounted on positioning disk；
Sliding jacking mechanism is made of sliding block, screw, which is mounted on fixed supported slab；Screw pushes sliding block along horizontal
Direction centering simultaneously holds out against parts to be processed, prevents part double swerve in process.
The technique effect of the utility model
A kind of special fixture of axial workpiece swinging bore hole of the utility model passes through fixture bottom using the above structure
Connection between seat, positioning disk, mandrel and sliding jacking mechanism, which can accurately stablize, clamps parts to be processed, and passes through
Fastening screw is accurately and quickly positioned, and the position degree deviation caused by secondary clamping is avoided, when reducing used in processing
Between, machining accuracy is improved, passing rate of processing is improved.

Specific implementation mode
As shown in Figure 1 to Figure 3, a kind of fixture suitable for axial workpiece swinging bore hole of the utility model, including bottom
Seat 7, positioning disk 6, mandrel 3 and sliding jacking mechanism 12；Base center is equipped with " I " fonts through-hole, and positioning disk 6 is inserted by positioning
Pin 5 and eyelet bolt 13 are connect with pedestal 7, and mandrel 3 is therethrough；Mandrel 3 is fixed on by sunk screw 10 on positioning disk 6,
Nut 9 is locked at again on pedestal 7, and after part to be processed is packed into mandrel 3 and centering, top is pre- by washer 2 and nut 1
Tightly；The sliding jacking mechanism 12 is made of sliding block, screw, straight pin, which is mounted on fixed supported slab 11
On, the fixed supported slab 11 is mounted on positioning disk 6；The pedestal 7 is embedded in bushing 8, and 3 bottom end of mandrel is made to be inserted in bushing 8
Form clearance fit, in this way in workpiece process positioning disk 6 and mandrel 3 can on pedestal 7 flexible rotating, therefore reach
It is lost caused by clamp body to frictional force is reduced.
Multiple grooves are provided in the positioning disk 6 and 7 mating surface of pedestal, the purpose is to reduce positioning disk 6 and pedestal 7
Between friction area, make its flexible rotation.
Straight pin is set between fixed supported slab 11 and sliding block, is further ensured that sliding jacking mechanism 12 always along level side
To movement, centering part to be processed.
In order to further decrease the frictional force in 3 rotation process of mandrel between pedestal 7, bushing 8 is replaced with into bearing.
In actual use, using a kind of fixture suitable for axial workpiece swinging bore hole of the utility model,
Its working principle is that：Clamp body is mounted on platen by the centering face being arranged on pedestal 7 first, with lathe T
Type groove bolt pre-fixes, with amesdial centering fixture, to center hole, tightening T-slot bolt tightening fixture.First workpiece diameter
It is inserted in mandrel 3, top washer 2 and nut 1 pre-tighten, and sliding jacking mechanism 12 is gently pushed sliding block alignment and top tight workpiece surveys end
Face, tightening nut 1 after centering.Boring machine is started, the hole for drilling part one side can be started, completion of processing extracts fastening screw 5
With loosen the eyelet bolt 13 on fixture, and positioning disk 6 is rotated 180 °, is inserted into fastening screw 5 and compressing fixture, so as to
Process the hole on part other end.
