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. According to the embodiment of the invention, the double-stroke air cylinder comprises a working cylinder, a pre-stroke cylinder and a pressurizing cylinder which are sequentially connected, and the working cylinder comprises a working cylinder barrel, a working piston and a working shaft; the working piston is arranged in the working cylinder barrel, and the working cylinder barrel is divided into a first air chamber and a second air chamber by the working piston; the working shaft is connected with the working piston for transmission; the pre-stroke cylinder comprises a pre-stroke cylinder barrel and a sleeve piston; the sleeve piston is arranged in the pre-stroke cylinder barrel, and the sleeve piston and the pre-stroke cylinder barrel form a fourth air chamber; the pressurizing cylinder comprises a pressurizing cylinder barrel, a pressurizing piston and a clamping groove shaft; the pressurizing piston is arranged in the pressurizing cylinder barrel, and the pressurizing cylinder barrel is divided into a fifth air chamber and a sixth air chamber by the pressurizing piston; the clamping groove shaft is connected with the pressurizing piston and is used for transmission; the double-stroke air cylinder further comprises a clamping and locking mechanism used for connecting the working shaft and the clamping groove 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...
