Abstract
Taut frock of automatic pinhole of piston machining relates to piston machining appurtenance technical field. Including positioning disk 5, master jaw 9 and tensioning mechanism, positioning disk and lathe main shaft be connected and be fixed, the master jaw fix in the hole of positioning disk, is connected through pin 3 between master jaw and the positioning disk, the periphery of pinning is equipped with spring 4, at master jaw internal assembly use the tensioning mechanism of pull rod as the center, tensioning mechanism, assembled in proper order on pull rod 1, go up V type piece 10, components of a whole that can function independently pinhole jack catch 7, fixed cover 13 and the nut 2 of 6, two symmetric distributions of V type piece down, have uide bushing 11 and side guard plate 8 around going up V type piece, there is apron 12 at the top. The utility model discloses it is convenient to have the clamping, the high and high positive effect of availability factor of positioning accuracy.
Description
Technical field
The utility model is related to Piston Machining aid technical field, particularly belongs to a kind of Piston Machining automatic pin hole and draws
Tight frock.
Background technology
In the automatic processing industry of piston, some manufacturing procedures need to be positioned using piston pin hole and clamping, simultaneously right
Pin-and-hole positioner has higher required precision.After conventional piston pin hole positioning and clamping mode often penetrates pin manually,
Main shaft tension positioning, production efficiency is relatively low.
Content of the invention
The purpose of this utility model is to provide a kind of Piston Machining automatic pin hole tension frock, to reach clamping side
Just, the high purpose of positioning precision.
Piston automatic pin hole provided by the utility model strains frock, including positioning disk, master jaw and tensioning mechanism, its
It is characterised by, described positioning disk is connected with machine tool chief axis and fixes, and described master jaw is fixed in the endoporus of positioning disk, and
Form gap cooperation therewith, be connected by pin between master jaw and positioning disk, pin periphery penetrates spring；Inside master jaw
It is assembled with the tensioning mechanism centered on pull bar, described tensioning mechanism, pull bar is assembled with successively, upper V-block, lower V-type
Block, two symmetrical split pin-and-hole claws, fixed cover and nut, have fairlead and side guard plate, top has around upper V-block
Cover plate；The two ends of positioning disk are respectively lathe positioning table, piston seam positioning table, are connected by bolt hole and machine tool chief axis between
Connect.
The piston automatic pin hole tension frock that the utility model provides, before clamping piston, pull bar stretches out so that lower V-type
Block moves upwards, and this makes two symmetrical split pin-and-hole claws, to pull bar 1 central motion, so that outside claw
Pin-and-hole claw withdraws.Load piston, using positioning disk top is cylindrical, piston seam is positioned, after piston clamping puts in place,
Pull bar moves downward, and in pulling, V-block moves downward, and makes two symmetrical split pin-and-hole claws simultaneously, to away from drawing
Bar center position moves so that pin-and-hole claw moves out, and automatically extends in piston pin hole.Therefore, the utility model has dress
Folder convenience, positioning precision height and the high good effect of service efficiency.
Brief description
Accompanying drawing part discloses the utility model specific embodiment, wherein,
Fig. 1, the utility model structural representation；
Fig. 2, the utility model overlooking the structure diagram.
Specific embodiment
As illustrated, positioning disk 5 is connected with machine tool chief axis and fixes, master jaw 9 is fixed in the endoporus of positioning disk 5, and
Form gap cooperation therewith, can move back and forth.It is connected by pin 3 between master jaw 9 and positioning disk 5, pin 3 periphery penetrates
Spring 4；The tensioning mechanism centered on pull bar 1 in master jaw 9 mounted inside, is assembled with, upper V-type on pull bar 1 successively
The symmetrical split pin-and-hole claw 7 of block 10, two, lower V-block 6, fixed cover 13 and nut 2, have fairlead around upper V-block
11, cover plate 12 is arranged at top.
Before clamping piston, pull bar 1 stretches out so that lower V-block 6 moves upwards, and this makes two symmetrical splits
Pin-and-hole claw 7, to pull bar 1 central motion, so that the outside pin-and-hole claw of claw 7 withdraws.Load piston, using positioning disk 5
Top is cylindrical to be positioned to piston seam, and after piston clamping puts in place, pull bar 1 moves downward, and in pulling, V-block 10 is transported downwards
Dynamic, make two symmetrical split pin-and-hole claws 7 simultaneously, to move away from pull bar 1 center position so that pin-and-hole claw to
Outer motion, stretches in piston pin hole.Back stay 1 continue to move downward so that master jaw 9 moves downward and compression spring 4, this
When this frock complete to the pin-and-hole of piston positioning and compress.
The two ends of positioning disk 5 are respectively lathe positioning table, piston seam positioning table, pass through bolt hole and machine tool chief axis between
Connect.
The positioning of piston pin hole is to rely on to install around pull bar 1, and two symmetrical split pin-and-hole claws 7 are realized
's.The folding of two pin-and-hole claws 7 is to be realized by upper V-block 10 and lower V-block 6.
When piston is installed, fairlead 11 and side guard plate 8 have direction positioning function, fairlead and cover plate to piston die cavity
12, it can be avoided that upper V-block and pull bar, cause to piston to wear and tear with piston contact.
Spring 4 between positioning disk 5 and master jaw 9 can realize pretension between the two.
