Abstract

The invention discloses an oil cylinder with adjustable piston stroke, which comprises a cylinder body, the front and the rear ends of the cylinder body are respectively provided with a front end cover and a rear end cover; the cylinder body is internally provided with a piston and a piston rod; the rear end cover is provided with a rear limiting seat which is internally provided with a limiting cavity which passes through a mounting hole on the rear end cover and is communicated with a rear cavity; the limiting cavity and the mounting hole are internally and movably provided with rear limiting rods, the front ends of which are matched with the bottom of the piston, and the rear ends thereof are positioned inside the limiting cavity; the rear limiting seat is provided with a screwed hole communicated with the limiting cavity; and the screwed hole is internally provided with an adjusting screw rod matched with the screwed hole, and the adjusting screw rod is provided with a locking nut matched with the adjusting screw rod. The oil cylinder has the advantages that the oil cylinder with the adjustable piston stroke can be used for conveniently adjusting the stroke of the piston and the piston rod as well as the length of the piston rod, thus leading the oil cylinder to be more conveniently and flexibly used and have wider application scope.

Description

technical field [0001] The invention relates to an oil cylinder, in particular to an oil cylinder with an adjustable piston stroke. Background technique [0002] The existing oil cylinder structure comprises: a cylinder body, a front end cover and a rear end cover are respectively arranged on the front and rear ends of the cylinder body, an oil return hole and an oil inlet hole are respectively arranged on the front end cover and the rear end cover, There is a cavity inside, and a piston is set in the cavity. The piston divides the cavity into two parts, the front cavity and the rear cavity. The oil return hole and the oil inlet hole are respectively connected with the front cavity and the rear cavity. The end is fixedly connected, and the front end of the piston rod extends out of the cylinder body through the front end cover. When in use, the oil cylinder is fixed on the processing equipment, the front end of the piston rod is connected with the workpiece, oil is fed into...
