[0002] A hollow shaft usually refers to a shaft with a through hole in the center of the shaft body. When the hollow shaft is processed, a hollow shaft inner diameter detection device is usually used to detect the inner diameter of the hollow shaft.

[0003] Application No. 202221878581.5 mentions a hollow shaft inner diameter detection device, including a column, which is arranged at the top of a bearing base. A laser rangefinder is installed on the side wall of the column through a strip groove. The inner cavity of the column is provided with a lifting mechanism for moving the laser rangefinder up and down. The lifting mechanism includes a lifting screw, a nut sleeve and a servo reduction motor. The lifting screw is rotatably arranged in the inner cavity of the column, and the servo reduction motor is fixedly arranged at the bottom end of the column. A strip through hole for connecting the laser rangefinder with the outer wall of the nut sleeve is opened on the inner wall of the strip groove. The output shaft of the servo reduction motor is arranged for transmission with the lifting screw. A display electrically connected to the laser rangefinder is fixedly installed on one side of the top of the bearing base.

[0004] A laser rangefinder is connected to a nut sleeve, and a lifting screw causes the nut sleeve to move up and down. A hollow shaft sleeve is arranged on the outside of the column, and then the nut sleeve drives the laser rangefinder to move up and down while the inner diameter of the inner wall of the hollow shaft is measured and detected. When the nut sleeve rotates with the lifting screw, there will be a certain friction, and then lubrication will be performed between the nut sleeve and the lifting screw. Usually, lubricating oil is applied to the outside of the lifting screw through the through hole on the column, but this method will have a limited operating space, which affects the lubrication effect of the lifting screw. The hollow shaft inner diameter detection device is not convenient for lubricating the outside of the lifting screw, and there are certain limitations. Utility Model Content
