Abstract

The invention discloses a taper sleeve type mechanical locking oil cylinder. The taper sleeve type mechanical locking oil cylinder comprises a cylinder barrel, a cylinder cover, a guide sleeve, a screw cap, a piston and a piston rod, and further comprises a taper top, a copper bearing bush and a taper sleeve; the piston coats the outer edge of the piston rod; the back section part of the cylinder barrel penetrates through the piston rod to fixedly connect with the cylinder cover; the front section part of the cylinder barrel is arranged between the screw cap and the guide sleeve; the taper top is connected with the back ends of the piston and the piston rod; the taper sleeve coats the outer edge of the taper top; the copper bearing bush is arranged in a mounting groove formed in the outer wall of the taper sleeve, and is in interference fit with the back section of the cylinder barrel; the cylinder cover is provided with a first oil port for inwards extending in the radial direction from the outer wall; an internal oil cylinder in fluid communication with the first oil port is arranged in the taper top; a second oil port for inwards extending in the radial direction is arranged at the middle section of the cylinder barrel; and sealing pieces are respectively arranged between the piston and the cylinder barrel, between the cylinder cover and the cylinder barrel, between the piston and the piston rod, between the guide sleeve and the piston rod and between the guide sleeve and the cylinder barrel. The taper sleeve type mechanical locking oil cylinder is simple in operation, excellent in tightness and reliable in working performance.

Description

Technical field [0001] The invention relates to a taper sleeve type mechanical locking oil cylinder. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has a simple structure and generally consists of a cylinder tube, a cylinder head, a guide sleeve, a nut, a piston, and a piston rod. The hydraulic oil cylinder works reliably. When it is used to realize reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is stable. Therefore, it is widely used in various mechanical hydraulic systems. However, the existing oil cylinder has the disadvantages of complicated operation, poor sealing performance, and axial displacement of the piston rod during locking. Summary of the invention [0003] The object of the present invention is to provide a taper sleeve type mechanical locking cylinde...
