Electric cylinder for control and positioning

Abstract

This invention relates to an electric cylinder for control and positioning, comprising a housing, which is sequentially secured by various components (motor, coupling housing, first connecting element, electric cylinder sleeve, second connecting element, and bearing seat). A shaft is placed inside the electric cylinder sleeve, and the shaft includes a bearing, a screw, and a movable piston. The motor is pivotally connected to the screw via a coupling and controls the rotation of the screw. The rotation of the screw further drives the movable piston to advance or retract. The movable piston has a movable element at an appropriate location, and the movable element is inserted and connected to a positioning sensing element. The sensing element can determine the position of the movable piston and transmit the information back to the control circuit. The motor can be controlled by the control circuit and rotated as needed to drive the shaft to advance or retract.

Claims

1. An electric cylinder for control and positioning, comprising: an electric cylinder, the outer casing of which is used to protect the internal components of the electric cylinder, and sequentially including a motor, a coupling housing, a first connecting element, an electric cylinder sleeve, a second connecting element, and a bearing seat; a shaft, the shaft including a bearing, a screw, and a movable piston, the bearing and the movable piston being connected by the screw, and the screw being connected to the motor by a coupling, wherein when the motor rotates, it drives the screw to rotate and causes the movable piston to advance or retract; a sensing element including a connecting end, the sensing element being disposed at an appropriate position on the side of the electric cylinder sleeve, for determining the position of the movable piston and transmitting the information to a control circuit.

2. The electric cylinder for control and positioning as described in claim 1, wherein a moving element is provided on the moving piston, and the moving element moves synchronously with the moving piston when the moving piston is pushed forward or retracted.

3. The electric cylinder for control positioning as described in claim 2, wherein the moving element is provided with a connection hole at an appropriate location for insertion and connection with the connection end of the sensing element, so that when the moving piston advances or retracts, the moving element drives the sensing element to move synchronously with the moving piston.

4. The electric cylinder for control positioning as described in claim 1, wherein the cylinder sleeve has a movable hole at an appropriate location on its side, the movable hole providing the necessary movement space for the connection end of the sensing element as the moving piston moves.

5. The electric cylinder for control positioning as described in claim 1, wherein the shaft is located inside and tightly fitted within the electric cylinder sleeve.
