Abstract

The invention provides a magnetic switch installation structure for controlling the stroke of a large-diameter cylinder. The magnetic switch installation structure comprises the cylinder, a magnetic switch A and a magnetic switch B. The cylinder comprises a cylinder body and a piston rod capable of reciprocating along the length direction of the cylinder body, the magnetic switch A and the magnetic switch B are both fixedly installed on the outer surface of the cylinder body, and the stroke of the cylinder is set as F. The distance between the installation position of the magnetic switch A and the bottom end of the cylinder body and the distance between the installation position of the magnetic switch B and the top end of the cylinder body are each one third of the stroke of the cylinder. Due to the adoption of the technical scheme, the actual effective stroke of reciprocating motion of the cylinder can be smaller than the rated nominal stroke and located in the middle of the range of the rated nominal stroke, and the influence of radial swing generated when the cylinder moves at the two ends of the rated nominal stroke on motion precision and corresponding control precision can be avoided; and the action accuracy of a power actuating mechanism and the control precision of the whole mechanical equipment can be conveniently improved.

Description

technical field

[0001] The invention belongs to the technical field of pneumatic equipment, and in particular relates to a magnetic switch installation structure for controlling the stroke of a cylinder with a large bore diameter. Background technique

[0002] Cylinders are widely used in various mechanical equipment. In these mechanical equipment, cylinders are used as reciprocating power actuators. In order to control the movement stroke of the cylinders, it is usually necessary to install corresponding magnetic switches on the cylinders. The magnetic switch cylinders are used to detect The position of the cylinder stroke can replace the machine-controlled valve or stroke switch, and there is no need to set a bumper at the end of the piston rod, so it is easy to use and compact in structure. High reliability, long life, low cost, fast switching response time, so it is widely used.

[0003] The existing cylinder products have been standardized and serialized, and people on...
