Small-size linear driver with location feedback

Abstract

The present invention discloses a small-size linear driver with location feedback. The small-size linear driver comprises a housing, the housing is internally provided with a motor, one end of the motor is connected with a second output shaft, the other end of the motor is connected with a first output shaft, one side of the motor is provided with a first reduction gear box, the other side of themotor is provided with a second reduction gear box, the first reduction gear box and the second reduction gear box are internally provided with reduction gear sets, and the first output shaft and thesecond output shaft are connected with the reduction gear sets. The structure by utilizing the output shaft of the reduction gear sets driven by the motor to drive a rotational potentiometer to monitor the flexible distance and the position feedback location of a push rod driven by the motor is employed to convert the rotation of the motor to the linear fore and aft motion of the push rod, and issimple in manufacturing and assembling production process technologies and low in cost, and the parts such as the rotational potentiometer and the reduction gear boxes have been industrialized so as to easily achieve large-scale production and manufacturing.

Description

technical field [0001] The invention belongs to the technical field of drives, and in particular relates to a small linear drive with positioning feedback. Background technique [0002] Small linear drives are used to drive robot joints, robot hands and other mechanisms to move according to the instructions of control signals, and are used in robots, toys and other industries. [0003] The existing linear drive manufacturing and assembly process is complex, costly, and difficult to achieve large-scale manufacturing; the structure and integration of the structure make it difficult to further miniaturize the volume, so as to optimize the internal space structure of the robot and apply it to more fields; Moreover, the structure and integration of the structure are complicated, the maintenance is not easy, and the use and maintenance costs are high. Therefore, we propose a small linear actuator with positioning feedback. Contents of the invention [0004] The purpose of the p...
