[0002] At present, the vertical machining center is a digitally controlled electromechanical-hydraulic integrated intelligent machine tool. Its structure is mainly composed of the host computer, control system, outer protective cover, tool magazine, water tank and other parts. The configured coolant is used to strengthen the spray cooling of the workpiece during processing. At the same time, the cutting fluid is easy to splash during the processing, and if the operator enters the rotary machine tool during processing, it will cause a great safety accident. Therefore, the existing machine tool Or machining centers are mostly equipped with protective doors, but although the existing protective doors can play a protective role, if the operator's arm is still within the scope of closing the door when the door is closed, it is easy to pinch the arm of the human body and cause a safety hazard.

The invention discloses a hand-pinch-preventing protective door for a machine tool. The hand-pinch-preventing protective door for the machine tool comprises a machine tool frame, a left sliding door, a right sliding door, an infrared emission lamp plate, an infrared receiving board, a programmable logic controller (PLC) main chip and an electromagnetic valve. The infrared emission lamp plate is mounted in an inner cavity of the right side of the left sliding door. The infrared receiving board is arranged in an inner cavity of the left side of the right sliding door. The right side of the bottom of the infrared receiving board is connected with the PLC main chip which is electrically connected with the electromagnetic valve. The top and the bottom of the electromagnetic valve are each provided with an air pressure connecting pipe, and the air pressure connecting pipes are connected with outer telescopic arms through air pressure telescopic arm connectors. According to the hand-pinch-preventing protective door for the machine tool, an infrared emitter, the infrared emission lamp plate, the infrared receiving board, the PLC main chip and the electromagnetic valve are arranged so that when the protective door is closed, human bodies can be effectively protected.
