Pneumatic connecting rod manipulator for preventing air cylinder failure

Abstract

The invention relates to a pneumatic connecting rod manipulator for preventing air cylinder failure. An air bag is fixedly installed at the rear end of an air cylinder piston, an air inlet and an airoutlet of the air bag are fixedly installed in an installation through hole, a movable piston is coaxially installed in an air storage blind hole in a sliding mode, and a first elastic element is arranged between the movable piston and the bottom of the air storage blind hole; a limiting hole is formed in an air cylinder extending rod, a limiting rod is slidably installed in the limiting hole, a sealing ring is arranged between the limiting rod and the limiting hole, the limiting rod is sleeved with a second elastic element, a wedge-shaped block with a first wedge-shaped face is fixedly installed on the movable piston, a second wedge-shaped face is arranged at one end of the limiting rod, and the first wedge-shaped face is attached to the second wedge-shaped face; and if a rear cavity of the air cylinder leaks, air in the air bag returns to normal pressure, the air bag resets, the first elastic element resets, and the limiting rod extends out of the limiting hole. According to the pneumatic connecting rod manipulator for preventing air cylinder failure, bottle body falling and liquid spilling caused by failure of the air cylinder can be effectively prevented, the cleanliness of theproduction environment is guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a pneumatic linkage manipulator for preventing cylinder failure. Background technique [0002] At present, in the field of machinery, unmanned operation and automatic production have become more and more common. In the process of mechanical processing, workpieces need to be clamped. In some dangerous mechanical processing, manipulators are often used to replace human hands to clamp workpieces, which greatly improves The safety of production and the improvement of production efficiency have led to the widespread use of manipulators in machining. Now many machines are designed with general-purpose manipulators. Pneumatic linkage manipulators are widely used. When using pneumatic linkage manipulators to grab For liquid bottles, the pneumatic connecting rod manipulator needs to be placed horizontally, the cylinder in the connecting rod manipulator is started, the piston rod is s...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to overcome the long-term high-pressure inflated state of the cylinder rear chamber in the traditional pneumatic connecting rod manipulator, the shell of the cylinder rear chamber is prone to leakage. Shrinkage, the jaws are far away from each other, the bottle body comes out of the jaws, the liquid spills, pollutes the production environment, and reduces production efficiency. A pneumatic connecting rod manipulator that prevents cylinder failure is provided.
