Abstract
The present invention 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, slide 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 mandrel both ends attaching nut of fixture proposed by the present invention is to realize the axially position of part, and pass through fixed supported slab and slide the horizontal location that jacking mechanism realizes part, fixture proposed by the present invention reduces the time used in part processing, improve the machining accuracy and processing efficiency of part, simple in structure, operation and it is easy to use the characteristics of.
Description
Technical field
The present invention relates to field of machining, specifically a kind of folder suitable for axial workpiece swinging bore hole
Tool.
Background technology
Bore hole is to be processed further with cutter to having drilled out, having forged or cast out hole, and bore hole can expand aperture, improves essence
Degree reduces surface roughness.Bore hole of the prior art is processed on lathe, boring machine or milling machine, typically to be added
Work parts fixation carries out part positioning and clamping, Boring can be carried out after positioning datum centering on lathe, 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.
Invention content
The problem of the technical problem to be solved by the present invention is to be directed to background technology, provides a kind of suitable for axis class zero
The fixture of 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, slide 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 set 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；
It slides jacking mechanism to be made of sliding block, screw, which is mounted on fixed supported slab；Screw pushes sliding block along level
Direction centering simultaneously holds out against parts to be processed, prevents part double swerve in process.The technique effect of the present invention
A kind of special fixture of axial workpiece swinging bore hole of the present invention using the above structure, by fixture base, is determined
Connection between position disk, mandrel and slip jacking mechanism, which can accurately stablize, clamps parts to be processed, and pass through positioning
Bolt is accurately and quickly positioned, and avoids the position degree deviation caused by secondary clamping, reduces the time used in processing,
Machining accuracy is improved, improves passing rate of processing.

Specific embodiment
As shown in Figure 1 to Figure 3, a kind of fixture suitable for axial workpiece swinging bore hole of the invention, including pedestal 7,
Positioning disk 6, mandrel 3 and slip jacking mechanism 12；Base center be equipped with " work " font through-hole, positioning disk 6 by fastening screw 5 with
And eyelet bolt 13 is connect with pedestal 7, mandrel 3 is therethrough；Mandrel 3 is fixed on by sunk screw 10 on positioning disk 6, nut 9
It is locked at again on pedestal 7, after part to be processed is packed into mandrel 3 and centering, top is pre-tightened by washer 2 and nut 1；It is described
It slides jacking mechanism 12 to be made of sliding block, screw, straight pin, which is mounted on fixed supported slab 11, described
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 and forms gap
Cooperation, in this way in workpiece process positioning disk 6 and mandrel 3 can on pedestal 7 flexible rotating, therefore reach reduction and rub
Power is wiped to be lost caused by clamp body.
Be provided with multiple grooves in the positioning disk 6 and 7 mating surface of pedestal, the purpose is to reduce positioning disk 6 and pedestal 7 it
Between friction area, make its flexible rotation.
Straight pin is set between fixed supported slab 11 and sliding block, is further ensured that and slides jacking mechanism 12 always along level side
To movement, centering part to be processed.
In order to further reduce the frictional force in 3 rotation process of mandrel between pedestal 7, bushing 8 is replaced with into bearing.
In actual use, a kind of fixture suitable for axial workpiece swinging bore hole using the present invention, work
It is as principle：Clamp body is mounted on platen by the centering face being arranged on pedestal 7 first, uses machine tool T-shaped groove
Bolt pre-fixes, with amesdial centering fixture, to center hole, tightening T-slot bolt tightening fixture.First workpiece diameter is inserted in
Mandrel 3, top washer 2 and nut 1 pre-tighten, and will slide jacking mechanism 12 and gently push sliding block alignment and top tight workpiece survey end face,
Tightening nut 1 after centering.Boring machine is started, can start to drill the hole of part one side, completion of processing extracts 5 He of fastening screw
The eyelet bolt 13 on fixture is loosened, and positioning disk 6 is rotated 180 °, fastening screw 5 and compressing fixture are inserted into, so as to add
Hole on work part other end.
