The invention relates to the technical field of oil cylinders, and discloses a mechanical self-locking spiral swing oil cylinder. The mechanical self-locking spiral swing oil cylinder comprises a spiral swing oil cylinder body, a locking end cover, a self-locking cylinder barrel, a self-locking piston, a tail cover, a locking spring, a spring sleeve, a steel ball, a fixing spring, a control bolt and the like, wherein an oil port A, an oil port B and a control port C are formed in the spiral swing oil cylinder barrel; and the control port C communicates with the oil port A and the oil port B through a valve set. The self-locking piston is located in the self-locking cylinder barrel and divides the interior of the self-locking cylinder barrel into an unlocking cavity and a locking cavity which do not communicate with each other, the unlocking cavity communicates with the control port C, and the locking cavity communicates with the unlocking cavity through the valve set in a one-way manner. The self-locking piston reciprocates under the action of the medium pressure between the unlocking cavity and the locking cavity, a locking pin is machined on one side of the self-locking piston, and an anti-rotation hole is machined in the self-locking cylinder barrel. According to the mechanical self-locking spiral swing oil cylinder, a simple mechanical structure is arranged so that the spiral swing oil cylinder can be automatically and mechanically locked and unlocked, and the work efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of oil cylinders, in particular to a mechanical self-locking spiral swing oil cylinder. Background technique [0002] The helical oscillating cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs rotary reciprocating motion. When the helical oscillating oil cylinder is used to realize the reciprocating rotary motion, there is no transmission gap and the motion is stable. Among them, according to the work requirements, sometimes the workpiece needs to keep its position unchanged for a certain period of time after rotating to a certain position or after the workpiece stops working. At this time, in order to prevent the workpiece from being displaced under the action of external force, gravity and other forces, it is necessary Lock the helical swing cylinder. [0003] At present, the self-locking of the spiral swing oil cylinder is mainly the self-locking of the o...
