Problems solved by technology

It consists of a cylinder body, a front gland and a rear gland placed at both ends of the cylinder body connected together, a piston rod and a piston placed in the cylinder body with one end extending out of the cylinder body through the front gland, respectively Placed between the piston and the cylinder body, between the cylinder body and the front gland, and between the piston rod and the front gland, there is an O-shaped sealing ring. The structure of the brake cylinder with this structure is cumbersome and the space structure is large. Inconvenient, because there are many connection activities between the parts of the cylinder, the airtightness is not good, and the service life is short

Abstract

The invention discloses a brake cylinder comprising a cylinder body and a rear cover, wherein the cylinder body is internally provided with a cylinder core; the cylinder core comprises a piston and a piston rod and is of an integral structure; the cylinder body is in an integral structure which contains a front cover and is molded through casting; and the piston rod of the cylinder core is in a hollow structure in which a spring is arranged. The brake cylinder is a single-action introduced-in ultrathin cylinder, has the advantages of simple structure, beautiful appearance, safety, reliability and long service life.

Description

technical field [0001] The invention relates to the field of pneumatic technology, in particular to a brake cylinder. Background technique [0002] Existing brake cylinders that are mainly used on woodworking machinery equipment make the brake pads at the shaft end firmly lock the moving machinery by the spring force of the cylinder so that they cannot move. It consists of a cylinder body, a front gland and a rear gland placed at both ends of the cylinder body connected together, a piston rod and a piston placed in the cylinder body with one end extending out of the cylinder body through the front gland, respectively Placed between the piston and the cylinder body, between the cylinder body and the front gland, and between the piston rod and the front gland, there is an O-shaped sealing ring. The structure of the brake cylinder with this structure is cumbersome and the space structure is large. Inconvenient, it is because there are many connection activities of each part of...
