Quick oil cylinder with supercharging function

Abstract

The invention relates to a quick oil cylinder with a supercharging function. The quick oil cylinder comprises an upper cylinder body, an upper cylinder cover, a connecting block, an upper piston body,a two-way sequence valve, a lower cylinder body, a lower cylinder cover and a lower piston body, wherein a first oil port and a second oil port are formed in the upper cylinder body; the two-way sequence valve is arranged in the upper piston body; a third oil port and a fourth oil port are formed in the lower cylinder body; and the lower piston body comprises a first guide rod, a lower piston anda second guide rod, a fourth flow channel with a downward opening is formed in the second guide rod, and the lower opening of the fourth flow channel forms a fifth oil port. The quick oil cylinder has the advantages of the simple structure and compact size, and the quick extension and the supercharging function can be realized.

Description

technical field [0001] The invention belongs to the technical field of oil cylinders, and in particular relates to a fast oil cylinder with supercharging function. Background technique [0002] The oil cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating motion, the deceleration device can be subtracted, and there is no transmission gap, and the motion is stable. Therefore, it is widely used in various mechanical hydraulic systems. The design and manufacturing process of existing conventional oil cylinders are very mature, but with the innovation and development of modern industrial technology, the shortcomings of conventional oil cylinders in the field of large-scale hydraulic machinery have always made hydraulic system designers feel helpless. The tonnage of the oil cylinder is directly ...

Problems solved by technology

The design and manufacturing process of existing conventional oil cylinders are very mature, but with the innovation and development of modern industrial technology, the shortcomings of conventional oil cylinders in the field of large-scale hydraulic machinery have always made hydraulic system designers feel helpless

In this way, while increasing power consumption, it also increases the load of the power system, and the cost of mechanical use is greatly increased.

Under complex working conditions, the power system cannot be effectively guaranteed, which has caused some large-scale hydraulic equipment to fail to operate normally. If the motor and oil pump are not increased accordingly, the hydraulic flow in and out of the front and rear chambers of the oil cylinder is too small, resulting in large oil cylinders. The working speed is too slow, affecting the working efficiency of the cylinder
