One side of the material transfer cylinder is movably connected with the swing rod through a connecting gear. A fixing frame is installed on one side of the swing rod. A fixing disc, a movable frame, a first motor and a threaded rod are arranged inside the fixing frame. The first motor is fixed on one side of the movable frame. The output end of the first motor is rotationally connected with the threaded rod.

[0013] Preferably, the fixing sleeve is movably connected to the ring rail through a ring sleeve.

[0014] Preferably, the spindle accurate stop method is as follows: First step: Install an infrared sensor inside the mounting seat and write a program inside the CNC lathe, and the program is: if the spindle receives the infrared signal of the infrared sensor, the spindle stops rotating, otherwise it continues to rotate; Second step: Move the turret so that a certain blanking device approaches the spindle. When the infrared sensor inside the blanking device is mapped to the spindle, the spindle stops rotating, otherwise it continues to rotate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1). For the CNC lathe with an automatic blanking mechanism and its spindle accurate stop method, due to the arrangement of the blanking device and the moving component, when the blanking operation of the CNC machine tool is required, the main gear is driven to rotate by the motor, the main gear then drives the sub-gear to rotate, and after the sub-gear rotates, it drives the screw to be screwed with the threaded hole, so that the sub-gear group climbs or descends along the inclined plane of the main gear. Also, because the bevel gear is meshed with the sub-gear, when the bevel gear rotates, it drives the bevel screw to climb inside the bevel screw hole. During the climbing process, the three clamping arms can be brought closer, and then by moving the turret close to the product and pressing the product into the mounting seat, the product can be fixed and pulled out, achieving the purpose of automatic blanking of the device, and solving the problems that manual blanking operation increases the labor intensity of personnel and reduces the processing efficiency of personnel.

[0017] (2) The numerically controlled lathe with an automatic stock pulling mechanism and its main shaft quasi-stop method are provided with a fixing device. The driving gear and the connecting gear are rotated by the first motor, and then the connecting gear drives the swing rod to rotate around the connecting gear. Subsequently, the first motor is driven to rotate to drive the screw rod to rotate, so that the fixing disk clamps the stock pulling device, and the stock pulling device can be transported to the turret without manual handling by personnel. The operation is simple and labor is saved.

[0018] (3) The numerically controlled lathe with an automatic stock pulling mechanism and its main shaft quasi-stop method are provided with a first socket on one side of the fixed sleeve. When the swing rod swings, the amplitude of the swing of the swing rod can be limited by the first socket, and when the swing rod contacts the first socket, the swing rod is buffered and rebounded by the spring, avoiding the problem that the loading cycle of the stock pulling device is too long due to excessive swing of the swing rod, which affects the loading efficiency of the stock pulling device.

[0038] Further, the main shaft accurate stop method is as follows: The first step: Install an infrared sensor inside the mounting seat 26 and write a program inside the CNC lathe.
