Lever type oil cylinder capable of steering by 360 degrees

Abstract

The lever type oil cylinder capable of steering by 360 degrees comprises a cylinder body and a rotary sealing cylinder cover seat, a guide hole is formed in the middle of the cylinder body, a bottom plug is arranged at the bottom end of the guide hole, a piston is arranged in the guide hole, a piston rod is arranged at the top of the piston, and the rotary sealing cylinder cover seat is arranged on the piston rod. And the top end of the piston rod penetrates through the top of the guide hole. The movable clamping balls are injected into the two semispherical clamping holes formed between the rotary sealing cylinder cover seat and the cylinder body, axial limiting of the rotary sealing cylinder cover seat is achieved, lubricating oil can be injected into the semispherical clamping holes, the clamping balls can provide guiding for rotation of the rotary sealing cylinder cover seat, the guiding effect is equal to the effect of a bearing, and the sealing effect of the rotary sealing cylinder cover seat is improved. The rotating resistance of the rotary sealing cylinder cover seat can be greatly reduced, the rotary sealing cylinder cover seat can rotate more flexibly and reliably, the requirement for locking at different angles is met, and the rotary sealing cylinder cover seat is flexible and changeable and more flexible to use.

Description

technical field [0001] The invention relates to the field of oil cylinders, in particular to a lever-type oil cylinder capable of 360-degree steering. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is stable. Therefore, it is widely used in the hydraulic system of various machines. In the field of fixing some fixtures, hydraulic cylinders are required to control the workpiece etc. to lock, but when the existing oil cylinders are locked, most of the output ends cannot be adjusted by rotation, the scope of use is limited, and the rotation of the oil cylinders with rotation adjustment is not flexible enough, and the adjustment is more laborious. At t...

AI Technical Summary

Problems solved by technology

When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is stable, so it is widely used in the hydraulic system of various machines. etc., but when the existing oil cylinders are locked, most of the output ends cannot be adjusted by rotation, and the scope of use is limited, and the rotation of the oil cylinders with rotation adjustment is not flexible enough, and the adjustment is more laborious. At the same time, the locking During the process, sometimes due to limited space, the use of oil cylinders will also be limited
