Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, does not restrict the protection scope of the present invention.
As depicted in figs. 1 and 2, a kind of novel pneumatic double tube chuck, chuck include left shell 1 and right shell body 2, left shell
1 and right shell body 2 in be respectively arranged with a bellmouth 3, and two bellmouths 3 communicate, the bellmouth 3 of left shell 1 and right shell body 2
It is inside respectively arranged with a shrinkable slips body component 4, two slips body components 4 are installed by 5 liftable of lifting device respectively
The backing pin 6 that oil pipe and barrier oil pipe are positioned for righting is additionally provided in left shell 1 and right shell body 2, in chuck, backing pin 6 is total
There are two, it is respectively set on the side wall of left shell 1 and right shell body 2 there are two backing pin hole 11, two 6 right-angled intersections of backing pin are mounted on
In chuck, the end of two backing pins 6 is separately fixed in four backing pin holes 11, and the right-angled intersection point of two backing pins 6 is placed exactly in
At the middle position of chuck；Lifting device 5 shares two groups, and two groups of lifting devices 5 include cylinder 51, bracket 52 and connecting rod
53, cylinder 51 herein is also changed to fluid cylinder, and two cylinders 51 are fixedly mounted in left shell 1 and right shell body 2 vertically respectively, and two
