The working principle is as follows: when the rectangular lock body is machined, the whole device is connected with an external power supply, so that the infrared sensor 11 and the piezoelectric sensor 31 are started simultaneously; then, a lock body to be processed is placed in the lock body placing groove 21 on the clamping fixed seat 19, a key on the lock body is placed in the key placing groove 20, and then the pedal plate 32 is stepped, so that the starting button 33 on the pedal plate 32 is pressed, and the circuits of the clamping device 8 and the correcting device 9 are simultaneously connected; after the circuit of the clamping device 8 is switched on, the pushing cylinder 23 is started, and after the pushing cylinder 23 is started, an upward pushing force is applied to one end of the clamping movable seat 22, because the clamping movable seat 22 is rotatably connected with the clamping fixed seat 19 through the rotating rod, when the pushing cylinder 23 pushes one end of the clamping movable seat 22 to move upward, the other end of the clamping movable seat 22 moves downward, so that the lock body clamping groove 24 on the clamping movable seat 22 is matched with the lock body placing groove 21, and the lock body is fixed up and down;

in the process that the moving rod 15 drives the mounting bar 16 to move, the side face of the mounting bar 16 passes through the infrared sensor 11, when the ground of the correcting block 17 is in contact with the top face of the material placing seat 2, the mounting bar 16 is just in the same horizontal plane with the infrared sensor 11, at this time, the mounting bar 16 can shield the infrared sensor 11, so that the infrared sensor 11 detects a return signal (the width of the correcting block 17 is smaller than that of the mounting conditioning block 16, and the correcting block 17 is not in the same vertical plane with the infrared sensor 11, so that the infrared sensor 11 cannot be shielded in the process that the correcting block 17 moves), at this time, the infrared sensor 11 can control the lifting cylinder 14 to stop and control the moving device 3 and the transmission motor 5 to start; after the lifting cylinder 14 stops, the moving rod 15 is driven to move upwards, and the moving rod 15 drives the mounting bar 16 and the correcting block 17 to move upwards together, so that the whole correcting device 9 is positioned above the groove milling piece 6, and subsequent groove milling cannot be influenced; after the moving device 3 is powered on, the appropriate moving hydraulic cylinder 27 is started, after the moving hydraulic cylinder 27 is started, the moving push rod 28 is driven to move towards the discharging seat 2, and the moving push rod 28 moves to push the mounting plate 4 to move, so that the mounting plate 4 can slide on the moving slide rail 26 and horizontally move towards the discharging seat 2; after the transmission motor 5 is started, the slot milling piece 6 can be driven to rotate at a high speed, and under the coordination of the movement of the mounting plate 4, the slot milling piece 6 can rotate at a high speed and approach to the material placing seat 2, so that the slot milling pieces 6 on the two sides can simultaneously and respectively polish and mill two side surfaces of the rectangular lock body between the clamping fixed seat 19 and the clamping movable seat 22 (wherein the slot milling piece 6 on one side is a slot milling cutter, and the slot milling piece 6 on the other side is a polishing block); in the moving process of the mounting plate 4, the mounting plate 4 can synchronously drive the positioning part 29 to move together, the positioning part 29 can drive the positioning needle 30 to move together, when the milling depth of the milling groove part 6 on the side surface of the rectangular lock body reaches a set value (or the milling time and the milling time reach a set value), the positioning needle 30 just contacts with the piezoelectric sensor 31, and then the piezoelectric sensor 31 can control the moving hydraulic cylinder 27 and the pushing cylinder 23 to stop simultaneously (namely a normally closed switch in a circuit of the moving hydraulic cylinder 27 in the piezoelectric sensor 31 is disconnected for a certain time), so that the moving hydraulic cylinder 27 drives the mounting plate 4, the transmission motor 5 and the milling groove part 6 to return to the initial positions; after the pushing cylinder 23 stops, the upward pushing force at one end of the clamping movable seat 22 disappears, and the other end of the clamping movable seat 22 moves upward, so that the lock body clamping groove 24 and the lock body placing groove 21 separate the rectangular lock body, and the processed rectangular lock body can be taken down to complete the work.
