Description

Technical Field

[0001] The present invention relates to the technical field of electric cylinders, and in particular to an integrated servo electric cylinder. Background Art

[0002] The electric cylinder is an electric actuator, a core component in the field of industrial automation, which can convert the rotary motion of the servo motor into linear motion and achieve high-precision linear motion control. The electric cylinder is specially designed for continuous motion, low to high loads (usually high speed), and can be used many times in its service life.

[0003] But the disadvantages of traditional electric cylinder systems include:

[0004] 1. Complex structure: Traditional servo electric cylinders are composed of multiple independent components, including motors, reducers, sensors, and controllers. These components need to be installed and debugged independently, which increases the complexity and workload of the system.

[0005] 2. Takes up a large space: Traditional servo electric cylinders are composed of multiple independent components, which require a large space when installed. This is disadvantageous for application scenarios with limited space.

[0006] 3. High installation and maintenance costs: Since the installation and debugging of traditional servo electric cylinders are relatively complicated, it is necessary to connect and adjust multiple components, which increases the time and cost of installation and maintenance.

[0007] In order to improve system performance, simplify installation and maintenance, and meet the needs of different application scenarios, it is urgent to provide an integrated servo electric cylinder design. Summary of the invention

[0008] The purpose of the present invention is to provide an integrated servo electric cylinder, comprising: a servo motor, an electric cylinder, a reduction box, and a driver.

[0009] The rotating shaft of the servo motor is connected with the gear of the reduction box.

[0010] The electric cylinder is connected with the gear of the reduction box.

[0011] The driver is electrically connected to the servo motor to control the movement of the servo motor, and then controls the extension and retraction of the electric cylinder through the gear transmission of the reduction box.

[0012] Furthermore, the electric cylinder includes but is not limited to a ball screw electric cylinder.

[0013] Furthermore, the ball screw electric cylinder is connected to the gear of the reduction box through a screw.

[0014] Furthermore, the reduction gearbox is a single-stage reduction gearbox.

[0015] Furthermore, the servo motor is a servo motor equipped with a power-off brake and an absolute encoder.

[0016] Furthermore, the driver controls the servo motor including position control, speed control, and torque control.

[0017] The technical effect of the present invention is unquestionable. The compact structure of the present invention and the integrated servo electric cylinder integrate the core components of the servo system into a compact mechanism, reducing the number and volume of components and adapting to application scenarios with limited space.

[0018] The present invention has high performance and precision, and the integrated servo electric cylinder integrates precise sensors and controllers, which can achieve more precise position and speed control and improve the performance and precision of the system.

[0019] The present invention simplifies installation and maintenance. Since the integrated servo electric cylinder has been pre-assembled and debugged, the user only needs to perform simple installation and wiring before use, thereby reducing the difficulty and cost of installation and maintenance.
