The fixed plate is provided with an oblique hole. A driving top is installed in the hole, and the left end of the fixed plate is provided with a tail journal, and the tail journal passes through the fixed sleeve, and the upper and lower ends of the fixed sleeve are connected with wrench handles.

As a preferred solution, the above-mentioned driving center for turning of the lathe that can guarantee the coaxiality, a spacer is installed at the connection between the fixed plate and the fixed sleeve on the left side.

As a preferred solution, the above-mentioned driving center for lathe turning with guaranteed coaxiality has two oblique holes opened on the fixed plate. Drive tops are installed in the inclined holes.

As a preferred solution, the above-mentioned driving center for lathe turning with guaranteed coaxiality, the tail journal is installed on the three-jaw chuck of the lathe.

As a preferred solution, the above-mentioned drive center for lathe turning with guaranteed coaxiality, the angle between the drive center and the center center is 10-30 degrees.

The utility model provides a driving top for lathe turning that can guarantee coaxiality. When actually used, the tail journal of the driving top is clamped on the three-jaw chuck of the lathe. Then pull the wrench to press the driving top so that the heights of the two driving tops from the fixed plate should be the same. Finally, put the end of the workpiece with the center hole on the center center and the two drive centers; press the other end of the workpiece with the tailstock center, and at the same time tighten the wrench once more before turning.

Beneficial effects: Compared with the prior art, the drive tip for lathe turning provided by the utility model which can guarantee coaxiality has the following advantages:

The utility model provides a driving top for lathe turning that can guarantee coaxiality, has reasonable structural design, convenient operation, stable and reliable clamping, and high coaxiality, and can especially meet the processing of workpieces with multiple journals and high coaxiality requirements. Requirements, the processed workpiece has high precision, high quality and strong practicability.
