Problems solved by technology

The main problem of this method is that the structure of the air motor is more complicated than that of the cylinder, it is prone to failure, and the cost of the air motor is relatively high
[0006] Another is to use the electric head as the power source to realize the rotation and lifting of the valve core, but the structure is also complex and prone to failure, and the torque is much lower than that of the pneumatic mechanism.

Abstract

The embodiment of the invention discloses a rotary lifting mechanism driven by a straight stroke actuator, which comprises an actuating component, a straight stroke push rod, a two-way thrust cylindrical roller combination bearing, the straight stroke actuator, a bolt type roller needle bearing and a support cylinder, the straight stroke actuator and the bolt type roller needle bearing are fixed on the support cylinder, a spiral groove is formed in the execution component, the bidirectional thrust cylindrical roller combination bearing is fixed at the protruding end of the execution component, and the support cylinder and the straight stroke actuator are fixed on the same axis. When the straight stroke push rod does axial linear motion under the action of the straight stroke actuator, the execution component does rotary lifting motion under the action of the spiral groove and the bolt type roller needle bearing. According to the embodiment of the invention, the execution component can rotate while performing linear motion.

Description

technical field [0001] The invention relates to the technical field of structural design, in particular to a rotary lifting mechanism driven by a linear actuator. Background technique [0002] This mechanism can be used in equipment that needs to convert lifting motion into rotary lifting motion, and has wide application prospects in petrochemical, chemical fiber and other industries, especially when the viscosity of the medium is high and some raw materials are easy to solidify and crystallize. Driven by the linear actuator, the rotating and lifting movement of the actuator is driven to achieve the effect of lifting and stirring. Typically used in the transmission system of plunger valves. [0003] The plunger valve is often used in the chemical industry where the medium is a melt, and it mainly plays the role of a switch. Due to the high viscosity of the medium, and some melts are easy to solidify and crystallize, it is required that the spool of the plunger valve can pl...
