Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment, and specifically relates to an automatic locking device for motors. Background Technology

[0002] Existing motors are normally directly connected to the reducer via a connecting shaft, and the operation of the male motor is controlled by a torque limiter. However, this direct connection causes frequent wear of the torque limiter's steel balls, which can cause significant damage to the reducer and requires regular replacement. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model provides an automatic motor locking device.

[0004] Technical solution: An automatic locking device for a motor, comprising: a motor, a coupling, a reducer, a locking shaft and a male connector, a reducer drive shaft, a cylinder, and a linear slide rail;

[0005] The motor is connected to the reducer via a coupling, which includes a first magnetic coupling and a second magnetic coupling. The first magnetic coupling is fixed on the shaft of the motor, and the first magnetic coupling and the second magnetic coupling are connected by magnetic attraction.

[0006] The locking shaft and male connector are designed separately from the reducer drive shaft;

[0007] The cylinder, acting as a power source, controls the locking device to move back and forth via a linear slide rail.

[0008] As an improvement, the gearbox drive shaft can be quickly replaced.

[0009] As an optimization: a preload spring is provided between the locking shaft and the male end and the reducer drive shaft. The preload spring is used to avoid hard contact between the locking shaft and the male end and the reducer drive shaft.

[0010] As an optimization, a protective plate is provided on the outside of the coupling, which serves as a safety protection during operation.

[0011] As an optimization: the motor is connected to the sensing sensor, and the start and stop of the motor are determined by the sensing sensor.

[0012] Beneficial effects: By utilizing the flexibility of the magnetic coupling, the device eliminates the rigid connection with the reducer and the torque limiter. Kinetic energy is transmitted through the magnetic coupling, and the motor start and stop are controlled by a fixed-position induction sensor. This reduces the long-term wear of the reducer and torque converter and lowers the device's failure rate. Attached Figure Description

[0015] Example

[0016] like Figure 1-2 As shown, an automatic locking device for a motor includes: a motor 1, a first magnetic coupling 2, a second magnetic coupling 3, a reducer 4, a locking shaft and male connector 5, a reducer drive shaft 6, a preload spring 7, a cylinder 8, a linear slide rail 9, and a protective plate 10.

[0017] The first magnetic coupling 2 is fixed to the shaft of the motor 1, and transmits kinetic energy to the second magnetic coupling 3 through magnetic attraction, driving the reducer 4 to operate. The locking shaft and male connector 5 are designed separately from the reducer drive shaft 6, allowing for quick replacement of the easily worn reducer drive shaft 6. A preload spring 7 is provided between the locking shaft and male connector 5 and the reducer drive shaft 6 to prevent hard contact between them. The cylinder 8 serves as a power source, controlling the locking device's forward and backward movement via a linear slide rail 9. The protective plate 10 provides safety protection during operation, and the start and stop of the motor 1 are determined by a sensor.

[0018] This invention utilizes the flexibility of a magnetic coupling to eliminate the rigid connection with the reducer and the torque limiter. Kinetic energy is transmitted through the magnetic coupling, and the motor start and stop are controlled by a fixed-position induction sensor. This reduces the long-term wear of the reducer and torque converter and lowers the failure rate of the device.
