| description | The invention discloses a sensing structure of a machine tool spindle. The sensing structure comprises a main spindle, and a cutter grabbing spindle located in the main spindle and coaxially arranged with the main spindle; the outside of the main spindle is fixedly sleeved with a shell coaxial with it; the first end of the shell body is fixed with an air cylinder, and the first end of the cutter grabbing spindle is in opposite to a piston of the air cylinder; a sensing ring is fixedly sleeved on the first end of the cutter grabbing spindle, and the sensing ring is also moved on the axial direction of the main spindle along the movement of the cutter grabbing spindle; a sensor is arranged on the shell body, and the sensor and the sensing ring are interacted so that the sensor transmits the position signal of the cutter grabbing spindle. The sensing structure of the machine tool spindle adopts a non-contact type approaching sensor, and is long in service life and low in cost; moreover, the sensor is installed on the shell body of the main spindle and convenient to replace, and can exactly and reliably sense the movement of the sensing structure of a machine tool spindle; the sensing structure is free from mis-pulling or clamping failure and other mis-operation for the cutter is not released. |
