Abstract

The invention provides a hydraulic oil cylinder barrel structure capable of preventing axial rotation. The hydraulic oil cylinder barrel structure comprises a cylinder barrel body, a fixing disc is welded to the surface of the cylinder barrel body, a piston rod is movably connected to the center of the top of the cylinder barrel body, and a first fixing block is welded to the center of the top of the piston rod; and a first connecting hole is formed in the center of the front face of the first fixing block, and clamping mechanisms are arranged on the two sides of the piston rod correspondingly. Through cooperation of moving columns, fixing boxes, first threaded sleeves, first threaded rods, bearings, moving plates, limiting columns and clamping seats, a user can conveniently clamp and limit the piston rod through the clamping seats, the piston rod is prevented from axially rotating during jacking, and through cooperation of mounting blocks, second threaded sleeves, second threaded rods and convex blocks, the user can conveniently clamp and fasten the two clamping seats; and through cooperation of positioning blocks and positioning rods, the user can conveniently assist the clamping mechanisms in limiting the piston rod.

Description

technical field [0001] The invention relates to the field of hydraulic cylinders, in particular to a hydraulic oil cylinder barrel structure for preventing axial rotation. Background technique [0002] Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. It is widely used in various mechanical hydraulic systems. A hydraulic cylinder is generally composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application, and other devices are essential. [0003] Both the cylinder barrel and the piston rod of the hydraulic cylinder are cylindrical. When the piston rod moves upward in the inner cavity of the cylinder barrel, the traditional structure of the cylinder barrel of the hydraulic cylinder cannot prev...
