Problems solved by technology

However, this structure can only protect the motor to a certain extent after the driving of the electric cylinder is stuck, and cannot protect the mechanical parts such as the screw transmission pair. Moreover, there is a certain time lag between the sensor and the controller, and the reliability is not high.

Embodiment Construction

[0038] as attached figure 1 As shown, a hydraulic buffer heavy-duty electric cylinder based on disc spring compression includes a servo motor 1, a reducer 2, a trapezoidal screw pair, a disc spring compression mechanism, a push rod 15, a cylinder barrel 20, a cylinder head 25, and a hydraulic system. 27.

[0039] The trapezoidal lead screw pair includes a lead screw 9 and a nut 10 that cooperate with each other. The lead screw pair can also be replaced with either a ball screw pair or a planetary roller screw pair.

[0040] The servo motor 1 is connected with the lead screw 9 through the reducer 2, and the rotational motion of the servo motor 1 is transmitted to the lead screw 9 through the action of deceleration and torque increase. 10 linear motion.

[0041] The disc spring compression mechanism includes a disc spring pre-compression adjusting nut 11 , a disc spring group 12 and a connecting sliding sleeve 13 . The disc spring group 12 is between the connecting sliding s...

Abstract

The invention relates to an electric cylinder, in particular to a hydraulic buffering heavy-load electric cylinder based on disc spring compression and a buffering control method.On the basis of the structure of an original electric cylinder, a buffering device with a disc spring set as a buffering piece is arranged between a nut and a push rod, and the design is small in occupied space and adjustable in buffering rigidity; a hydraulic buffer system is matched, when the loading force is suddenly increased, the influence of impact load on mechanical parts is remarkably reduced by adjusting the swing angle of the variable pump and the rotating speed of the servo motor, and the reliability and the service life of the electric cylinder are improved.

Description

technical field [0001] The invention relates to an electric cylinder, in particular to a hydraulic buffer heavy-duty electric cylinder based on disc spring compression and a buffer control method. Background technique [0002] The electric cylinder uses electricity as the power source, uses various types of motors to drive different forms of lead screws or nuts to rotate through the reducer, and converts the helical motion between the components into the linear motion of the nut or lead screw, and then the nut or lead screw rotates. Drive the push rod or load to do reciprocating linear motion. Electric cylinders are widely used in aerospace, robotics, defense equipment, ships, simulation platforms, CNC lathes and other high-end equipment fields due to their high energy efficiency, pollution-free and excellent control performance, and are gradually replacing traditional of hydraulic cylinder actuators. However, the biggest bottleneck and shortcoming of electric cylinder tec...
