Abstract

The invention relates to the technical field of rotary oil cylinders, in particular to a rotary oil cylinder which comprises a cylinder body, a main piston is installed in the cylinder body, cavities are formed in the upper portion and the bottom of the interior of the cylinder body, small pistons are arranged on the left sides of the interiors of the cavities, and rear spring seats are arranged on the right sides of the interiors of the cavities. A front valve element spring seat is arranged on the left side of each rear spring seat, a compression spring is arranged between the rear spring seat and the front valve element spring seat, a steel ball is movably installed on the left side of the front valve element spring seat, a valve element is arranged on the left side of the steel ball, a reversing valve element is arranged on the left side of the valve element, and a front valve set gland is arranged on the right side of the rear spring seat. The purpose that the rotary oil cylinder can conduct automatic pressure maintaining under the condition of power failure or pressure loss of a hydraulic pump is achieved, a clamp is in an automatic clamping or loosening state all the time, and therefore the phenomenon that due to the fact that the rotary oil cylinder stops working, parts are loosened is avoided, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of rotary oil cylinders, in particular to a rotary oil cylinder. Background technique [0002] The hydraulic transmission structure generally includes a hydraulic pump and a hydraulic cylinder. The motion state of the hydraulic cylinder is controlled by the oil pressure output by the hydraulic pump. The output motion of the hydraulic cylinder is generally linear motion and rotary motion. In the field of mechanical transmission that needs to perform rotary motion, You need to use the rotary cylinder; the rotary cylinder is a tightly assembled accessory, which uses hydraulic pressure to gather a very high torque in a small space, and is usually used in machining machine tools, especially for the installation of parts processed by machine tools Provides clamping force and is very convenient to operate. However, the rotary oil cylinder in the prior art may encounter a sudden power failure of the machine tool or...
