Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, an intelligent electric screwdriver device provided by the embodiment of the present invention comprises a housing 1 with a closed top and an open bottom, a rotary encoder 2 is fixedly arranged at the upper end inside the housing 1, a motor 3 is arranged below the rotary encoder 2, a motor shaft 31 is arranged in the motor 3, the upper end of the motor shaft 31 is fixedly connected with a rotating shaft 21 of the rotary encoder 2, the lower end of the motor shaft 31 is connected with an input shaft 41 of a speed reducer 4, a torque sensor 5 is fixedly arranged at the lower end inside the housing 1, an output shaft 42 of the speed reducer 4 is sequentially connected with the torque sensor 5 and a connecting rod 6 from top to bottom and penetrates out of the housing 1, and the connecting rod 6 is connected with a batch of heads;

the rotary encoder 2, the motor 3 and the torque sensor 5 are electrically connected to a control device (not shown), respectively.

Furthermore, a spring 8 is fixedly sleeved at the upper end of the batch head 7, and a sleeve 9 is slidably arranged in the middle of the batch head 7.

Further, a backing ring 10 is provided at the upper end of the spring 8.

Further, the bottom of the housing 1 is fixedly provided with a flange 11, the lower end of an output shaft 41 of the speed reducer 4 is connected with the flange 11 through a first bearing 12, the upper end of the connecting rod 6 is connected with the flange through a second bearing 13, and the lower end of the connecting rod 6 is connected with the flange 11 through a third bearing 14.

In particular, the batch header 7 is a line batch or a cross batch.

The utility model provides an intelligence electricity is criticized device's theory of operation is:

firstly, a control device drives a motor shaft 31 of a motor 3 to rotate, and a rotary encoder 2 records the angular speed and the angular displacement of the rotation of the motor shaft 31 and transmits the acquired angular speed and the angular displacement to the control device;

then, the motor shaft 31 drives the input shaft 41 of the speed reducer 4 to rotate, the input shaft 41 of the speed reducer 4 drives the output shaft 42 to rotate, the torque sensor 5 senses the torque generated by the output shaft 42 of the speed reducer 4 and transmits the acquired torque to the control device;

then, the output shaft 42 of the reducer 4 drives the connecting rod 6 to rotate, the connecting rod 6 drives the screwdriver bit 7 to rotate, and the screwdriver bit 7 drives the screw to rotate;

finally, the control device compares the received angular speed and angular displacement with the preset angular speed and angular displacement, and if the data of the received angular speed and angular displacement are the same, the number of turns of the screw locking is in place; meanwhile, the control device compares the received torque force with a preset torque force, and if the data of the received torque force and the preset torque force are the same, the torque force of the screw locking is in place (namely the screw is locked); if one of the angular velocity, the angular displacement and the torsion is different from the preset data, the control device drives the motor shaft 31 of the motor 3 to rotate again and to do reciprocating motion circularly until the angular velocity, the angular displacement and the torsion are the same as the preset angular velocity, the angular displacement and the torsion, and therefore the locking of the screw is completed.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
