Abstract

The invention discloses a double-acting high-thrust-output hydraulic oil cylinder, which comprises a main cylinder body and a main piston, wherein oil inlet and outlet holes are formed in the upper segment and the lower segment of the main cylinder body respectively; the main piston is provided with a main piston rod; the main piston, the main piston rod and the main cylinder body are in coaxial movable seal fit with one another; the main piston rod is provided with a secondary cylinder, which is in dynamic seal fit with a secondary piston along a longitudinal axis; the main piston rod is provided with a main piston rod oil circuit hole; the secondary piston is provided with a secondary piston rod, and is supported at the bottom of the main cylinder body; the secondary piston rod is provided with a flow guide hole along the longitudinal axis; and the secondary piston rod is provided with a secondary piston rod oil circuit hole which is communicated with the flow guide hole. According to the double-acting high-thrust-output hydraulic oil cylinder, a composite hydraulic cylinder body and double-acting piston combined structure is adopted, so that the dynamic acting area of the piston is increased in comparison to the hydraulic cylinder in the prior art, so that the outward output power of the hydraulic cylinder is effectively increased. The double-acting high-thrust-output hydraulic oil cylinder is compact in structure and is skillful in design, the space in the main piston rod is effectively used to form the working area of the piston, and the hydraulic thrust can be increased by 30-60 percent.

Description

technical field [0001] The invention belongs to the technical field of mechanical power transmission, and further belongs to the technical field of hydraulic transmission devices, in particular to a compact double-acting high-thrust output hydraulic oil cylinder. Background technique [0002] The hydraulic cylinder is the most important actuator in the hydraulic system. It converts hydraulic energy into mechanical energy, and cooperates with various transmission mechanisms to complete various mechanical movements. The hydraulic cylinder has the characteristics of simple structure, large output force, stable and reliable performance, convenient use and maintenance, etc., and is widely used in various machinery. In the practical application of hydraulic cylinders, in some special places, due to the limitation of equipment structure, the space for installing hydraulic cylinders is limited. Since the output force of the hydraulic cylinder is proportional to the piston are...
