Built-in air suction cylinder

Abstract

The invention relates to a cylinder, in particular to a built-in air suction cylinder with an air suction function. The built-in air suction cylinder comprises a cylinder body, a piston rod and a piston. The piston consists of an upper piston and a lower piston. The upper piston and the lower piston are arranged on the piston rod at a certain distance to enable the chamber of the cylinder to form two piston chambers. The middle section of the chamber of the cylinder forms an air inlet chamber. An air chamber air outlet is arranged in the cylinder body corresponding to the air inlet chamber. An axial air flow passage is arranged in the piston rod. A radial air outlet is arranged in the body of the piston rod at a position where the air inlet chamber is arranged. The radial air outlet is connected with the outlet end of the axial air flow passage. The inlet end of the axial air flow passage stretches out of the external end of the piston rod. The invention aims at designing the built-in air suction cylinder with the air suction function, a small size and a small structure. Compared with the prior art, the built-in air suction cylinder provided by the invention has the advantages that the cylinder has dual functions of a manipulator and an adsorption mechanism, the production cost is low, the workpiece adsorption accuracy is high, the working response time is short, convenience is provided for the reasonable layout of automatic corollary equipment and the space is saved.

Description

technical field [0001] The invention relates to an air cylinder used on automatic mechanical equipment, in particular to a built-in air suction cylinder with air suction function. Background technique [0002] At present, automatic equipment at home and abroad generally use manipulators and suction cups to grab small workpieces after they are transported in place. The traditional manipulator adopts cylinder movement and external suction cup assembly. The air pressure sucks the workpiece through the air pipe, air pipe joint and suction cup, and the working process is completed by the telescopic movement of the cylinder. Because the suction cup assembly must be installed at the lower end of the cylinder, the external suction cup assembly occupies a certain space. In addition, because the movement of the cylinder simultaneously brings the leather tube and the air pipe joint to follow the expansion and contraction movement, the leather tube and the air cylinder joint are fatig...

AI Technical Summary

Problems solved by technology

Since the suction cup assembly must be installed at the lower end of the cylinder, the external suction cup assembly occupies a certain space

In addition, since the cylinder moves with the leather tube and the air pipe joint to follow the expansion and contraction movement, the leather tube and the cylinder joint are fatigued under high-frequency movement, which affects the life of the manipulator adsorption mechanism.
