Unit 7 is oriented to, and the clamping precision of rear chuck is improved.
A kind of pipe cutting machine is as follows with the course of work of pneumatic rear chuck:
1, rear chuck is unclamped:
(1) push rod of cylinder 5 travels forward, and pushing block 6 is pushed to move, and pushing block 6 drives the second of the second claw unit 7
Drive rod 71 moves, and the second drive rod 71 is rotated around the second shaft 72, and the other end of the second drive rod 71 drives the second sliding block 73
By center, radially side is mobile, passes through 6 → the second drive rod of push rod → pushing block, 71 → the second sliding block 73 → the of cylinder 5
Forward extending out for 5 push rod of cylinder is moved the outwardly radial sliding along end plate 9 for becoming the second claw 74 by two claws 74,
Realize the release of the second claw unit 7.
(2) when the push rod of cylinder 5 travels forward, the cylinder body of cylinder 5 moves backward under the action of reaction force, cylinder body
Band piston 3 moves backward, in order to protect cylinder 5 not collide, end cap 2 is arranged in the rear end of piston 3, cylinder 5 is sealed in work
In plug 3, when piston 3 moves backward, the first connecting rod 41 hinged with piston 3 pulls the movement of the first drive rod 42, the first driving
Bar 42 is rotated around first rotating shaft 43, and the other end of the first drive rod 42 drives the first sliding block 44 by center radially sidesway
It is dynamic, pass through cylinder body → 3 → first connecting rod of piston, 41 → the first drive rod, 42 → the first sliding block, 44 → the first claw of cylinder 5
45, the movement backward of 5 cylinder body of cylinder is become to the outwardly radial sliding along end plate 9 of the first claw 45, realizes first
The release of claw unit 4.
At this point, the first claw unit 4 and the second claw unit 7 all open, the as releasing orientation of chuck.Continue to gas
Pressure maintaining, mechanism are in force balance state, guarantee the reliability of releasing orientation.
2, rear chuck clamps:
(1) cylinder 5 push rod withdraw, drive pushing block 6 move backward, while pushing block 6 drive the second drive rod 71 around
The rotation of second shaft 72, the other end of the second drive rod 71 drive the second sliding block 73 mobile to the center of end plate 9, cylinder 5 is pushed away
The recovery movement backward of bar becomes sliding laterally along the inside of 9 face of end plate for the second claw unit 7, realizes the second claw
The clamping of unit 7.
(2) when the push rod of cylinder 5 moves backward, the cylinder body of cylinder 5 is slowly transported forward due to the reduction of air pressure in cylinder 5
Dynamic, when piston 3 travels forward, the first connecting rod 41 hinged with piston 3 pushes the movement of the first drive rod 42, the first drive rod 42
It is rotated around first rotating shaft 43, the other end of the first drive rod 42 drives the first sliding block 44 mobile to the center of end plate 9, by cylinder 5
Travelling forward for cylinder body becomes radially sliding along the inside of end plate 9 for the first claw 45, realizes the first claw unit 4
It clamps.
At this point, the first claw unit 4 and the second claw unit 7 are all tightened, the as clamped condition of chuck.Continue to gas
Pressure maintaining, mechanism are in force balance state, guarantee the reliability clamped.
Above-mentioned technical proposal is one embodiment of the present invention, for those skilled in the art, at this
On the basis of disclosure of the invention application method and principle, it is easy to make various types of improvement or deformation, be not limited solely to this
