Abstract

The invention discloses an air cylinder with an end cover sealing structure. The air cylinder with the end cover sealing structure comprises a cylinder body, a front end cover, a rear end cover, a piston and a piston rod. The front end cover and the rear end cover are connected with the cylinder body through a pull rod. The piston and the piston rod are both arranged inside the cylinder body. One end of the piston rod is connected to the piston, and the other end of the piston rod stretches out of the front end cover. The convex portion where the front end cover and the cylinder body are combined and the convex portion where the rear end cover and the cylinder body are combined are respectively provided with a sealing groove, sealing rings are arranged in the sealing grooves, and the sealing rings which are arranged in the sealing grooves are O-shaped sealing rings. The sealing rings are in close fit with the sealing grooves and the inner wall of the cylinder body to form a cylinder body sealing structure. The air cylinder with the end cover sealing structure effectively solves the problem that an existing air cylinder depends on screwing force of the pull rod to guarantee the sealing effect, and has the advantages of being strong in sealing reliability, easy to assemble, high in percent of pass, low in repair rate and the like.

Description

technical field [0001] The invention relates to a cylinder, in particular to a cylinder with an end cover sealing structure. Background technique [0002] Cylinders are generally composed of cylinder blocks, end covers, pistons, piston rods and seals. The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion. It converts the pressure energy of compressed air into mechanical energy, and the driving mechanism performs linear reciprocating, swinging and rotating motions. At present, the cylinder has been widely used in printing, semiconductor, automation control, robot and other fields. [0003] Such as figure 2 As shown, usually the front end cover, the rear end cover and the cylinder body of the currently used cylinder are connected in an axial sealing manner, that is, gaskets are installed between the cylinder front cover and the cylinder rear cover and the cylinder body respectively, and then through The tightening of the tie ...
