Abstract
The utility model discloses a screw rod adjusting nut locking device which comprises a screw rod main shaft and a locking ring. The screw rod main shaft comprises a connecting pin rod and a connecting screw. The locking ring comprises a C-shaped locking body. The two tail ends of the locking body are respectively provided with a connecting flange, each connecting flange is provided with a locking through hole, and a locking pin is arranged in each locking through hole. According to the screw rod adjusting nut locking device, the locking ring arranged on the screw rod main shaft is used, the two tail ends of the locking ring are respectively provided with one connecting flange, so that after connection is accomplished by a user through connecting threads, the two connecting flanges are fixedly connected by the locking pins, the firmness of connection of the screw rod main shaft and the locking ring is greatly improved, displacement of the screw rod main shaft is prevented, and the accuracy of a swinging wheel screw rod of a machine tool is greatly improved. The screw rod adjusting nut locking device is simple in structure, obvious in effect and high in practicality.
