Its main work is to compile machining programs, that is, to convert the original manual work into computer programming. Of course, it requires experience in manual machining. The CNC index numerically controlled machine tool is programmed and controlled by numerical control machining language, usually G-code. The numerical control machining G-code language tells the machining tool of the numerically controlled machine tool which Cartesian position coordinates to adopt, and controls the feed speed of the tool and the spindle speed, as well as functions such as tool changer and coolant. Numerical control machining has great advantages compared with manual machining. For example, the parts produced by numerical control machining are very precise and have repeatability. Numerical control machining can produce parts with complex shapes that cannot be completed by manual machining. Numerical control machining technology has now been widely promoted, and most machining workshops have the ability of numerical control machining.

[0035] The fixed seat 31 is fixedly installed on the inner bottom surface of the operation chamber 11 for placing the lifting robotic arm 32. An air pipe (not shown in the figure) is built inside the fixed seat 31. The air inlet pipe 311 is opened on one side of the fixed seat 31.

One end of the air delivery pipe 323 is connected to the cleaning nozzle 322, and the other end is connected to the built-in air pipe of the fixed seat 31. The camera 34 is fixedly installed on the inner side wall of the operation chamber 11 and is used to cooperate with the equipment program to identify the position of the automotive safety housing fitting 5;

[0036] The cleaning assembly 4 includes a chip cleaning box 41, a first cleaning brush barrel 42, and a second cleaning brush barrel 43;

[0037] The chip cleaning box 41 is fixedly installed on the inner bottom surface of the operation chamber 11, on the other side of the fixed seat 31. A motor (not shown in the figure) is built inside the chip cleaning box 41 to provide power for the two cleaning brush barrels.

[0038] The automotive safety housing fitting 5 is placed on the processing machine tool 21, between the first clamping block 22 and the second clamping block 221;

[0039] The CNC machining machine 1 is powered by an external power supply to drive the internal components;

[0040] The CNC machining machine 1 is equipped with an equipment program. The equipment program can control the start and stop of the processing machine tool 21, the movement and stop of the two processing tool heads, the movement and stop of the two clamping blocks, the movement and stop of the lifting robotic arm 32, the clamping and loosening of the lifting robot hand 321, the start and stop of the air compressor 33, and the start and stop of the motor built inside the chip cleaning box 41;

[0041] The processing machine tool 21, the two processing tool heads, the two clamping blocks, the lifting robotic arm 32, the lifting robot hand 321, the air compressor 33, the motor built inside the chip cleaning box 41, and the camera 34 are all connected to the equipment program for signal transmission.

[0042] Machining clamping operation:

[0043] When the staff needs to process the automotive safety shell fitting 5, the staff first manually moves the movable door panel 12 to the left to open it, then puts the automotive safety shell fitting 5 into the CNC machining machine 1. Then the staff turns on the external power supply. At this time, the CNC machining machine 1 starts, and the equipment program starts. The equipment program first identifies the position of the automotive safety shell fitting 5 through the camera 34. Then the equipment program controls the lifting robotic arm 32 to move downward to the notch of the automotive safety shell fitting 5. The lifting robotic hand 321 clamps it through the notch. After the clamping is completed, the equipment program controls the lifting robotic arm 32 to move upward and place the automotive safety shell fitting 5 between the two clamping blocks. Then the equipment program controls the two clamping blocks to move closer to each other. When the two clamping blocks complete the clamping of the automotive safety shell fitting 5, the equipment program controls the lifting robotic hand 321 to loosen. Then the staff controls the machining tool 21 to start through the equipment program, and the two cutting heads start to process the automotive safety shell fitting 5. After the processing is completed, the equipment program controls the next operation;

[0044] Through the coordinated use of the lifting robotic arm 32, the lifting robotic hand 321, the camera 34 and the equipment program, there is no need for manual placement of the automotive safety shell fitting 5, which prevents the staff's hands from being scratched by the residual machining chips during the placement process, reduces potential safety hazards, reduces the occurrence of safety accidents. Manually placing the automotive safety shell fitting 5 consumes a large amount of physical strength of the staff and reduces production efficiency.

[0045] Chip cleaning operation:

[0046] After the above operations are completed, the device program controls the chip cleaning operation. When a large amount of chips are generated after the automotive safety housing fitting 5 has undergone the above processing, the chips are mostly metal wires and will wind around the automotive safety housing fitting 5. It is somewhat dangerous for the staff to clean them manually. The device program identifies the position of the automotive safety housing fitting 5 through the camera 34, and then controls the lifting manipulator arm 32 to move to the notch position of the automotive safety housing fitting 5 and controls the lifting manipulator 321 to clamp. After the lifting manipulator 321 clamps, the device program controls the air compressor 33 to start. The air compressor 33 pumps compressed air into the built-in air pipeline of the fixed seat 31. After being transmitted through the air delivery pipe 323, it is ejected from the cleaning nozzle 322. The remaining iron chips on the automotive safety housing fitting 5 are first blown away with compressed air. The device program sets the iron chip blowing time to T1. When the time T1 arrives, the device program controls the air compressor 33 to turn off. The lifting manipulator arm 32 moves upward and then leftward to the upper part of the chip cleaning box 41. Then the device program controls the lifting manipulator arm 32 to move up and down according to the set values. The device program sets the moving speeds to M1 and M2, where M1 is the minimum value and M2 is the maximum value, and the moving distance is N1. At this time, the device program controls the air compressor 33 to turn on. The lifting manipulator arm 32 first moves downward by a distance of N1 at a moving speed of M2. When the downward moving distance of N1 is reached, the device program controls the lifting manipulator arm 32 to move upward by a distance of N1 at a moving speed of M1. When the upward moving distance of N1 is reached, the device program controls the lifting manipulator arm 32 to move downward by a distance of N1 again, continuously making up and down reciprocating movements for a duration of T2. When the time T2 arrives, the device program controls the air compressor 33 to turn off, and prepares to enter the next operation;

[0047] Through the coordinated use of the lifting manipulator arm 32, the air compressor 33 and the device program, after the processing is completed, the lifting manipulator arm 32 can be controlled to make up and down reciprocating movements at different speeds to simulate manual use of different forces to shake the automotive safety housing fitting 5, and then compressed air is ejected, which can shake off the remaining metal wire chips on the automotive safety housing fitting 5. There is no need for the staff to manually use a compressed air gun for cleaning, effectively reducing the cleaning time and improving the production efficiency. The staff does not need to touch the just-processed automotive safety housing fitting 5, which can prevent the staff from being scratched by metal wire chips, reduce the occurrence of safety accidents, and reduce the safety hazards during production.

[0048] Secondary cleaning operation:

[0049] After the device program completes the above operations, a secondary cleaning operation is performed. The device program controls the lifting manipulator arm 32 to move leftward above the chip cleaning box 41, and then the device program controls the built-in motor of the chip cleaning box 41 to start, and the two cleaning brush cylinders start. At this time, the device program controls the lifting manipulator 321 to rotate, rotates the automotive safety housing fitting 5 to be perpendicular to the ground, and then the device program controls the lifting manipulator arm 32 to move downward, moves the automotive safety housing fitting 5 into the middle of the two cleaning brush cylinders for cleaning. The two cleaning brush cylinders can brush the tightly wound metal wires remaining on the automotive safety housing fitting 5 into the chip cleaning box 41, perform secondary cleaning on the automotive safety housing fitting 5, ensure that there is no chip residue on the automotive safety housing fitting 5, and facilitate subsequent transportation and production;

[0050] Through the coordinated use of the chip cleaning box 41 and the device program, the automotive safety housing fitting 5 can be secondarily cleaned. The tightly wound chips are brushed off by the two cleaning brush cylinders, improving the cleaning effect, preventing the staff from being scratched by the chips when taking the automotive safety housing fitting 5, ensuring the production safety of the staff. There is no need for manual cleaning by the staff, and the chips are centrally cleaned in the CNC machine 1, which can ensure the cleanliness of the production workshop floor, prevent chip contamination of the production environment, and reduce the daily maintenance cost of the factory.
