Mechanical follow-up oil cylinder assembly

Abstract

The invention discloses a mechanical follow-up oil cylinder assembly which comprises a cylinder body, wherein one end of the cylinder body is connected with a cylinder cover; a piston end passes through the cylinder cover and the cylinder body and is mounted in the oil cylinder assembly to divide the oil cylinder assembly into a left chamber and a right chamber; a control valve assembly is mounted in the piston assembly; a control valve rod in the control valve assembly is connected with a toggle block on a driven member; oil inlet holes, oil control holes, oil return holes and oil outlet holes are respectively formed in the cylinder body, the piston assembly and the control valve assembly. The mechanical follow-up oil cylinder assembly has the characteristics of being perfect in function, simple in structure and convenient to mount and maintain; through adjusting the layout between a control valve and an execution oil cylinder assembly or an air cylinder, a cylinder body or a piston and a control valve in the execution oil cylinder assembly or the air cylinder are designed into an integrity in the design of a hydraulic or pneumatic system, so that the space expense on the layout in the design is decreased to the greatest extent. The oil cylinder assembly is simple and compact in structure and accurate to control and can be used for rapidly providing assistance and removing assistance.

Description

[0001] technical field [0002] The invention relates to a mechanical follow-up oil cylinder assembly, which belongs to the technical field of oil cylinder assemblies. Background technique [0003] At present, hydraulic and pneumatic technology is widely used in production and life. Whether it is hydraulic overweight machine, hydraulic machine feed system or other hydraulic and pneumatic systems, it includes hydraulic or pneumatic control valves and executive cylinder assemblies or cylinder. However, the control valves of these systems are mostly arranged separately on the installation platform outside the executive cylinder assembly or cylinder. When controlled by mechanical valves, they are generally installed near the operation platform and connected to the cylinder assembly or cylinder through oil pipes or air pipes. , When controlled by a solenoid valve, the solenoid valve is generally installed on the cylinder assembly or the cylinder block, and then connected to the ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a mechanical follow-up cylinder assembly to solve the problem that the distance between the control valve and the actuator cylinder assembly or the cylinder in the hydraulic or pneumatic system is too far, which affects the accuracy of the action during manual control. When the system structure and layout are complex, etc.
