Abstract

The invention relates to a multi-stage air cylinder, in particular to a bidirectional on-load multi-stage air cylinder capable of being mounted horizontally, and belongs to the technical field of multi-stage air cylinders. The bidirectional on-load multi-stage air cylinder comprises a telescopic head, a front end cover, a front inner end cover, an inner telescopic rod, an air channel hollow rod, an outer telescopic rod, an outer cylinder body, an inner piston, an outer piston, a rear end cover and a piston position induction mechanism. The front end cover is provided with a front air opening.The rear end cover is provided with a rear air opening. A radial air channel is arranged on the outer piston in the radial direction. The outer end of the radial air channel communicates with the front air opening. The inner end of the radial air channel communicates with the rear end of the air channel hollow rod. The front end of the air channel hollow rod communicates with the front end of theinner piston. An axial air channel is arranged on the outer piston. The rear end of the axial air channel communicates with the rear air opening. The front end of the axial air channel communicates with the rear end of the inner piston. The bidirectional on-load multi-stage air cylinder is simple, compact and reasonable in structure, on-load telescopic motion of the inner piston and the outer piston is achieved through the dual air openings and an inner air way, the use requirements of horizontal and vertical mounting are met, and the range of application is widened; and meanwhile piston position detection of the air cylinder can be achieved.

Description

technical field [0001] The invention relates to a multistage cylinder, in particular to a bidirectional load multistage cylinder capable of horizontal installation, belonging to the technical field of multistage cylinders. Background technique [0002] In pneumatic systems, multi-stage cylinders are widely used components in pneumatic circuits. At present, the multi-stage cylinders on the market are mainly single-acting multi-stage cylinders. The single-acting multi-stage cylinders can only be installed vertically. The piston rod protrudes vertically upwards and retracts under the action of an external force. Cannot run horizontally. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, so as to provide a two-way load multi-stage cylinder that can be installed horizontally, and realize the pneumatic expansion and contraction function of the piston rod of the multi-stage cylinder through the internal air circuit, wh...
