The working principle of the invention is: as shown in figure 3, needing to supply A chamber, at this time air pump when needing to clamp workpiece
By the left side fixture body radial direction venthole on distributing ring, fixture body, the outer valve radial direction venthole on outer valve 7 to outer valve
7 supply gas, at this point, gas push inner valve stem 8 moves to the right, and one end of inner valve stem 8 pushes the steel ball in right spool mobile,
Steel ball is set to be detached from right side gasket 12, so that the compressed air of B chamber on fixture body be made to pass through right side fixture body radial direction venthole, outer
Valve body right chamber body, the central blind hole of right side fastening plug screw 13, outer valve central cavity and the entrance of intermediate holder body radial direction venthole
In atmosphere.Meanwhile air pump pushes the steel ball in left spool to be moved to the left supplying gas for outer valve 7, and steel ball is made to be detached from left side sealing
Pad 6, gas pass through the central blind hole of left side fastening plug screw 2, multiple plug screw ventholes on left side fastening plug screw 2, on fixture body
Axial venthole enter the A chamber of fixture body, the A chamber of fixture body is inflated to realize, realizes and clamps workpiece.
As shown in figure 4, needing to supply B chamber, air pump passes through on distributing ring, fixture body at this time when needing to loosen workpiece
Intermediate fixture body radial direction venthole, the outer valve radial direction venthole on outer valve 7 supply gas outer valve 7, at this point, gas push
Inner valve stem 8 moves to the left, and the other end of inner valve stem 8 pushes the steel ball in left spool mobile, so that steel ball is detached from left side close
Packing 2, to make the compressed air of A chamber on fixture body by fixture body axial direction venthole, outer valve left chamber body, left side fastening spiral shell
The central blind hole and left side clamp body radial direction venthole of plug enter in atmosphere.Meanwhile air pump pushes right valve to supplying gas for outer valve 7
Steel ball in core moves right, and steel ball is made to be detached from right side gasket, and the central blind hole of gas process right side fastening plug screw, right side are tight
Gu the right side fixture body venthole on multiple plug screw ventholes, fixture body on plug screw enters the B chamber of fixture body, thus realization pair
The B chamber of fixture body is inflated, and workpiece is loosened in realization.
It completes one through two above circulation fixture body piston to stretch, a contracting function.
Assembling process of the invention is as follows: left side gasket 6 is put into the hole of outer valve 7, successively puts left side steel ball 4,
It in left side spring 3 to be put into left side fastening plug screw, is screwed into 7 screw hole of outer valve together, until left side fastens plug screw 2 and left side
Until gasket 6 contacts.3 sealing rings 1 are inserted on outer valve 7, are filled together by inner valve stem 8 and its upper seal 29
Enter in outer valve 7.Above each part is fitted into as a whole in the hole of fixture body 1.It is being sequentially loaded into right side gasket, right side steel
After fastening plug screw and thrust bearing on the right side of ball, right side spring, sealing ring is inserted in big plug screw, is screwed into 1 right side screw hole of fixture body,
Until right side fastening plug screw and right side gasket are in close contact.
The present invention is mounted on fixture body 1, so that fixture body piston is completed one and is stretched, a contracting function.It realizes in clamping, heavy caliber
Body function.Instead of expensive external import valve group and structure is complicated, and service life is short, the high domestic valve group of failure rate.
