Machine tool workpiece clamping detection device

The utility model relates to a machine tool workpiece clamping and detecting device which comprises a machine tool table top, and a workpiece position used for placing a workpiece is arranged on the machine tool table top. The mounting seat can move along XYZ above the table top of the machine tool and is detachably provided with a cutter used for cutting a workpiece or a detection tube extending downwards in the vertical direction, and the detection tube can be bent under collision and does not rebound; under the condition that the detection tube is mounted on the mounting seat and a workpiece is placed at the workpiece position, the length of the detection tube is set to be that the detection tube does not collide with the workpiece in the process of translating to pass through the upper part of the workpiece at the self-reset height, and collides with the workpiece in the process of translating to pass through the upper part of the workpiece at the non-reset height; and the tool setting gauge is arranged o
