Pressure cylinder with floating piston rod

Abstract

The invention discloses a pressure cylinder with a floating piston rod. The pressure cylinder with the floating piston rod comprises a rear end cover, a cylinder barrel, a front end cover, the floating piston rod, a piston rod fixing flange, a piston and an oil cup, wherein the front end cover and the rear end cover respectively cover the two sides of the cylinder barrel, the cylinder barrel is of a hollow structure, a cavity is formed between the front end cover and the rear end cover, the cavity is a pressurizing cavity, the piston is arranged in the cylinder barrel, one end of the floating piston rod is installed on the piston through the piston rod fixing flange in a floating mode, a gland flange covers one end of the pressurizing cavity of the front end cover, the other end of the pressurizing cavity in the front end cover is sleeved at the other end of the floating piston rod, and is matched with the floating piston rod in a sealing mode, a through hole which is communicated with the pressurizing cavity is formed in the side wall of the front end cover, the oil outlet end of the oil cup is connected with the through hole, and an oil pressing opening which is communicated with the pressurizing cavity is formed in the gland flange. The pressure cylinder with the floating piston rod is simple in structure and easy to machine, improves efficiency, and solves the problems that leakage happens and machining is difficult due to decentration of piston rods of pressure cylinders.

Description

technical field [0001] This patent relates to a booster cylinder, in particular to a piston rod booster cylinder. Background technique [0002] At present, the general pressurized cylinder is directly installed on the piston rod. The concentricity requirements of the piston rod and the cylinder barrel are relatively high, the processing is difficult, and the probability of oil leakage is also relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a floating piston rod booster cylinder, which can effectively solve the problem of oil leakage from the booster cylinder, reduce the difficulty of processing and assembly, have a simple structure, improve booster efficiency, and be easy to implement. [0004] Technical scheme of the present invention is: [0005] Floating piston rod pressurized cylinder, including rear end cover, cylinder barrel, front end cover, floating piston rod, piston rod fixing flange, piston, oil cup, front ...
