[0026] like Figures 1-7 The servo locking device with buffer function shown includes a mounting base 1. A servo motor 2 is mounted on the top of the mounting base 1, with its output end facing downwards. A connector 301 is mounted on the output end of the servo motor 2. An open limiting groove 302 is formed at the bottom of the connector 301. A lifting rod 303 is mounted inside the open limiting groove 302. A first return spring 304 is mounted on the top of the lifting rod 303 and connected to the inner wall of the open limiting groove 302. A locking component is mounted on the bottom of the lifting rod 303. The lifting rod 303 is connected to a limiting block 4 through a first bearing 305 and passes through the limiting block 4. One end of the limiting block 4 is fixed to the mounting base 1. It should be noted that the mounting base 1, when mounted on a robotic arm, can move freely to the desired working position, thereby achieving the effect of positioning screws and nuts. The above structure is a mature existing technology and will not be described in detail here.
[0027] Specifically, the locking assembly comprises an electric screwdriver head 3, and the top end of the electric screwdriver head 3 is connected with a lifting rod 303 through a quick connector 306. It should be noted that the electric screwdriver head 3 is detachably arranged through the quick connector 306, and the electric screwdriver head 3 of the required specification can be quickly installed and detached on the lifting rod 303 according to requirements. The lifting rod 303 is matched with a servo motor 2, a connecting head 301, an open limiting sliding groove 302, a first reset spring 304 and a first bearing 305, so that the lifting rod 303 can freely rotate and move up and down by a stroke. The stroke is the depth of the open limiting sliding groove 302, so that the working position of the electric screwdriver head 3 is adjusted, and the torque adjustment and buffer locking of the electric screwdriver head 3 are realized.
[0028] Specifically, the locking assembly further comprises a guide nose 5, and the top end of the guide nose 5 is connected with the lifting rod 303 through an auxiliary quick connector.

The second reset spring 505 is sleeved outside the limiting rod 504. A nut positioning groove 6 is formed at the bottom end of the guide nose 5. It should be noted that the nut positioning groove 6 is arranged to facilitate quick positioning of the nut. When the guide nose 5 is pressed down to lock the nut, the L-shaped support seat 503 is stressed to rise through the sliding seat 502 matched with the guide rail 501. At this time, the limiting rod 504 rises with it, until the second reset spring 505 is compressed to the limit position, so as to achieve the buffering effect. When the guide nose 5 is locked and separated from the nut, the second reset spring 505 acts to reset the guide nose 5. The guide nose 5 can freely rotate and move up and down by a stroke.
[0029] Specifically, a first open through hole is formed in the limiting block 4 for mounting the first bearing 305. Locking bolts are arranged at the opening of the first open through hole. A second open through hole is formed in the L-shaped support seat 503 for mounting the second bearing 506. Locking bolts are arranged at the opening of the second open through hole. It should be noted that the first bearing 305 and the second bearing 506 can be installed and detached according to requirements, so as to facilitate replacement of the electric screwdriver head 3 and the guide nose 5 of the required specification.
