An automatic switching device that controls the free switching between multiple gas channels

Abstract

The invention discloses an automatic switching device for controlling free switching between multiple gas circuits. The automatic switching device comprises a controller, a U-shaped body, a servo air cylinder, a pull plate, a guide rail and a gas circuit switching piston; the controller is electrically connected with the servo air cylinder, the servo air cylinder is arranged in a U-shaped groove of the U-shaped body, and one end of the servo air cylinder extends out of the U-shaped groove to be connected with the pull plate; the guide rail and the gas circuit switching piston are arranged in first cavities in parallel parts on the two sides of the U-shaped body, one end of the guide rail extends out from the parallel parts to be connected with the pull plate, and the other end of the guide rail is connected with the gas circuit switching piston; and a plurality of output holes communicated with each first cavity are formed in the corresponding parallel part at intervals, a plurality of protrusions matched with the output holes are arranged on the gas circuit switching piston, second cavities communicated with the first cavities are further arranged in the parallel parts, and input holes communicated with the second cavities are formed in the parallel parts. The automatic switching device is accurate in positioning, high in switching speed, high in efficiency, small in size, simple in structure and convenient and rapid to install, and truly meets the requirement of actual application.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to an automatic switching device for controlling free switching among multiple gas channels. Background technique [0002] In the automatic production process, it is often necessary to use multiple cylinders to control different operations, and the control sequences of multiple cylinders are different. Therefore, it is usually necessary to design a special control system to control the opening and closing of different cylinders through different air pipes, and the number of air pipes is too large. Most of them will cause problems such as cumbersome layout, mutual entanglement, and difficult inspection and maintenance, especially in narrow working areas. Therefore how to design a set of cylinder automatic switching device that takes up little space, is easy to install, and has high control precision is a technical problem to be solved urgently by those skilled in the art.
