[0006] Preferably, the driving assembly comprises a servo motor, the output end of the servo motor extends to the inside of the connecting groove and is transmission-connected to a driving screw rod, and the outer side of the driving screw rod is threadedly connected to a driving collar.

[0007] Preferably, two driving clamping plates are fixedly provided on the upper surface of the driving collar.

[0008] Preferably, the propulsion link is located between two driving clamping plates.

[0011] Technical effects and advantages of the utility model:

[0012] (1) The device can push the push-in plate to move by means of a driving assembly, so that the tailstock body of the machine tool moves on the guide plate, so that one end of the tailstock body of the machine tool where the workpiece is placed is close to the cutter head of the CNC machine tool, and the driving ring and the driving clamping plate are driven to move by means of a servo motor and a driving screw, so that the driving clamping plate drives the push-in plate to move, and the horizontal position of the L-shaped connecting plate and the proximity switch can be adjusted by means of an adjustment handle, and the proximity switch is adjusted to a suitable position in advance. When the tailstock body of the machine tool is close to the position, the proximity switch turns off the servo motor to avoid excessive displacement of the tailstock body of the machine tool, thereby solving the problem that the tailstock of a CNC machine tool is generally transported by manpower, so that one end of the tailstock of the machine tool where the workpiece is loaded is close to the cutter head of the machine tool, and it is laborious to push the tailstock of the machine tool by manpower, and it is not easy to position the tailstock of the machine tool in time during the pushing process, which easily causes the relative position of the tailstock of the machine tool to be too close to the cutter head of the machine tool;

[0013] (2) After the proximity switch is adjusted, the device can be plugged into the second adjustment slot near the L-shaped connecting plate by means of the T-shaped positioning plate, and plugged into the positioning through hole to limit the positioning component.
