Problems solved by technology

In order to make the cylinder output higher pressure, schemes such as increasing the diameter of the cylinder barrel and connecting more cylinders in series are often adopted. These schemes greatly increase the overall volume of the cylinder and directly affect the size and weight of the entire welding machine.
In the prior art, it is usually impossible to balance the installation size and output pressure of the cylinder

Abstract

The invention discloses a double-stroke air cylinder. The double-stroke air cylinder comprises a front cylinder and a pressurizing cylinder which are connected with each other, wherein the front cylinder comprises: a front cylinder barrel; a front cylinder piston which is arranged in the front cylinder barrel, wherein the front cylinder barrel is divided into a first air chamber and a second air chamber by the front cylinder piston; a front cylinder shaft which is connected with the front cylinder piston and is used for transmission; the pressurizing cylinder comprises: a pressurizing cylinder barrel; a pressurizing cylinder piston which is arranged in the pressurizing cylinder barrel, wherein the pressurizing cylinder barrel is divided into a third air chamber and a fourth air chamber by the pressurizing cylinder piston; and a pressurizing cylinder shaft which is connected with the pressurizing cylinder piston and is used for transmission. The double-stroke air cylinder further comprises: a clamping and locking mechanism used for connecting the front cylinder shaft wherein the pressurizing cylinder shaft, and the clamping and locking mechanism comprises a first connecting part which is connected with the front cylinder piston and used for connecting the front cylinder shaft and the pressurizing cylinder shaft; and a second connecting part which is matched with the first connecting part, is arranged on the pressurizing cylinder shaft and is used for being connected with the front cylinder shaft. According to the double-stroke air cylinder, the size and the output pressure of the air cylinder are both considered.

Description

technical field [0001] The invention relates to the technical field of cylinders, in particular to a double-stroke cylinder. Background technique [0002] The cylinder is widely used in various industries because of its variable length and convenient operation, especially its ability to effectively complete linear motion. The double-stroke cylinder is more and more widely used because of its longer stroke and higher output pressure. [0003] At present, with the development of the automobile manufacturing industry, there are higher requirements for the volume and output pressure of welding equipment. Cylinder components in welding equipment are important power components. In order to make the cylinder output higher pressure, schemes such as increasing the diameter of the cylinder barrel and connecting more cylinders in series are often adopted. These schemes greatly increase the overall volume of the cylinder and directly affect the size and weight of the entire welding ma...
