Limit is with, while cost can also increase.
The content of the invention
The purpose of the present invention is exactly a kind of simple structure, the crawl scope provided to solve the deficiency of prior art
Greatly, cylinder body is small, the three-jaw cylinder of low cost.
The present invention is to realize above-mentioned purpose using following technical solution：A kind of three-jaw cylinder, it is characterised in that it
Including cylinder body, it is arranged on the positioning chuck of cylinder ends, is movably hinged in three swing arms on positioning chuck, cylinder body connection drives
Three swing arms swing around hinged support, and the pendulum angle scope for making swing arm is 1-90 °.
As further illustrating for such scheme, the cavity of piston one and accommodating piston one is provided with the cylinder body, it is living
Cavity is divided into air cavity one and air cavity two by plug one；Cylinder body is provided with the stomata one connected with air cavity one, is provided with and the company of air cavity two
Logical stomata two.
Further, the piston one is connected with piston two, and piston two is connected with swing arm, and positioning chuck is provided with appearance piston
Two along the axial direction telescopic moving of cylinder body chamber.
Further, the piston two includes the axle portion set along the axial direction of cylinder body and is arranged on axle portion end
Connecting seat, the end of three swing arms is flexibly connected with connecting seat.
Further, the connecting seat is in disk form, and be perpendicularly fixed at for axle portion by fastener in cylinder by axle portion
On piston one.
Further, the periphery of the positioning chuck is provided with groove position corresponding with swing arm, and swing arm is L-shaped；L-type swing arm
Turnover position is positioned in groove position by hinge, and one end of swing arm is provided with universal ball end, and the connecting seat periphery of piston two is provided with
With the hole position of everything bulb male-female engagement.
It is of the invention to be using the above-mentioned technical solution beneficial effect to be reached：
The present invention sets positioning chuck using in the end of cylinder body, and the groove for installing swing arm is set in the periphery of positioning chuck
Position, promotes swing arm, swing arm to do oscillating motion around fulcrum by the piston of cylinder body, makes its pendulum angle scope for 1-90 °, and existing skill
Art is compared, and crawl scope is bigger, and cylinder body can accomplish smaller, and cost greatly reduces.
