At present, the machining and feeding of parts such as casings of large bypass ratio aircraft engines are carried manually and then placed on a machine tool. And after the parts are machined, the workers take the parts off the machine tool. The defects of the mode are that the manual labor consumption is large, the workpiece needs to be installed and taken down manually, and the part is easy to knock and scrap in the carrying process. The robot is adopted to automatically place the workpiece to be machined on the machine tool, and the robot takes the workpiece off the machine tool after the workpiece to be machined is machined. The robot is used for automatically feeding and discharging materials, so that the labor intensity of workers can be reduced, and the labor cost is saved.
Disclosure of Invention
According to the invention, the robot is used for automatically grabbing the workpiece to be machined and placing the workpiece on the machine tool, and the robot automatically takes the workpiece off the machine tool after the workpiece is machined. The invention relates to a rotary worktable, which is provided with four stations, wherein two stations of the four stations are used for placing workpieces to be machined, and the other two stations are used for placing finished workpieces after machining. The execution of all actions and the confirmation of the completion of the actions are controlled by a PLC and a position detection switch, so that the positions of grabbing and placing parts are accurate, and the positioning is reliable.
An end effector is designed for automatically picking machined parts.
By applying the technology of the invention, eight parts can be automatically processed after one-time feeding. The whole big bypass of the invention is changed into the processing flow of feeding and discharging the parts such as the case of the aircraft engine:
1) the worker places eight workpieces to be processed on the initial workpiece placing station of the turntable. Automatically detecting whether the part is placed correctly or not at the part placing station, and automatically correcting again until the part is placed correctly if the part is not placed correctly;
2) the robot picks the workpiece and places it on the machine tool fixture. Feeding back a part clamping correct signal to a controller through airtightness detection on the clamp, and sending a machining instruction to a machine tool by the controller to start machining the part;
3) returning the robot end effector to the initial position;
4) and after the workpiece is machined, rotating the turntable by 90 degrees anticlockwise. After the position is in place, feeding back a position signal to the controller and executing the next step;
5) the end effector picks up a workpiece from the machine tool and places it on the turntable. After the position is in place, feeding back a position signal to the controller and executing the next step;
6) the turntable is rotated 90 degrees further clockwise. After the position is in place, feeding back a position signal to the controller and executing the next step;
7) the above work was repeated 3 times (four parts at one station were finished). The turntable is rotated 180 degrees clockwise. After the position is in place, feeding back a position signal to the controller and executing the next step;
8) the end picking device grabs and places the workpiece to be machined on a machine tool fixture. Feeding back a part clamping correct signal to a controller through airtightness detection on the clamp, and sending a machining instruction to a machine tool by the controller to start machining the part;
9) returning the robot end effector to the initial position;
10) and after the workpiece is machined, rotating the turntable by 90 degrees anticlockwise. After the position is in place, feeding back a position signal to the controller and executing the next step;
11) the end effector picks up a workpiece from the machine tool and places it on the turntable. After the position is in place, feeding back a position signal to the controller and executing the next step;
12) the turntable is rotated 90 degrees further clockwise. After the position is in place, feeding back a position signal to the controller and executing the next step;
13) repeating the work for 3 times (finishing the processing of four parts on the other station);
14) taking down four machined workpieces at an initial position;
15) the turntable is rotated 90 degrees counterclockwise. The whole process is finished;
16) and the positioning surfaces of all stations of the rotary table are automatically cleaned, so that the parts are reliably positioned on the rotary table.
