Automatic return device based on stepping motor

Abstract

The invention discloses an automatic return device based on a stepping motor. The automatic return device is characterized by being composed of torsion springs, axial holes, a radial through hole, a stepping motor rear shaft sleeve, a stepping motor rear shaft, a stepping motor power output shaft, a stepping motor shell, a device shell fixing support and fixing bolts. The stepping motor rear shaft sleeve is fixed on the stepping motor rear shaft in an interference fit manner; the two axial holes and the radial through hole are distributed on the shaft sleeve, and the two axial holes are respectively communicated with the radial through hole; axial feet at the two ends of the two torsion springs are connected with the shaft sleeve and the device shell fixing support respectively, the two axial feet connected with the shaft sleeve of the rear shaft of the stepping motor are bent by 90 degrees through the axial holes to be restrained in the radial through holes, and the other two axial feet are connected to the fixing support in a welded mode; and the device shell fixing support is fixed to the stepping motor shell through four fixing bolts. The angular displacement can be reset when the stepping motor is not driven, and the rapid return function is realized.

Description

technical field [0001] This patent belongs to the field of electric control machinery, and in particular relates to an automatic return device for a stepping motor. Background technique [0002] As an actuator, the stepper motor converts electrical pulses into angular displacements. It is one of the key products of mechatronics and is widely used in various automation control systems. With the development of microelectronics and computer technology, the demand for stepper motors is increasing day by day, and they are used in various national economic fields. [0003] At present, most scientific and technological innovation projects use stepper motors as CNC motors. When the stepper driver receives multiple pulse signals, it drives the stepper motor to output torque in the set direction and rotate the set angle; when the signal disappears , the stepper motor no longer outputs torque and cannot return to its position automatically. This patent provides an automatic return de...
