[0026] like Figures 1 to 6As shown, a tensioning wheel production line includes a frame and a first process processing machine tool 1, a first machine tool 2, a second machine tool 3, a third machine tool 4 and a fourth machine tool 5, wherein the first machine tool 2 performs the second process processing, the second machine tool 3 performs the third process processing, the third machine tool 4 and the fourth machine tool 5 can both perform the fourth process processing, the first machine tool 2 and the second machine tool 3 are arranged side by side, the third machine tool 4 and the fourth machine tool 5 are arranged side by side and are located behind the first machine tool 2 and the second machine tool 3, the frame is provided with a feeding conveyor belt 6 for feeding materials to the first machine tool 2 and a conveying mechanism 7 for conveying the workpieces processed by the first machine tool 2 and the second machine tool 3 to the third machine tool 4 and the fourth machine tool 5, and the frame is also provided with a conveyor belt 6 located at the The workpiece turning mechanism 8 is disposed outside the end of the conveying mechanism 7. The frame is also provided with a first loading and unloading manipulator 9 for grabbing the workpiece from the loading conveyor belt 6 to the first machine tool 2 and removing the processed workpiece from the first machine tool 2. The frame is also provided with a second loading and unloading manipulator 10 for grabbing the workpiece processed by the first machine tool 2 to the second machine tool 3, and removing the workpiece processed by the second machine tool 3 and placing it on the conveying mechanism 7. The frame is also provided with a third loading and unloading manipulator 12 running between the conveying mechanism 7, the workpiece turning mechanism 8, the third machine tool 4 and the discharge conveyor belt 11. The frame is also provided with a fourth loading and unloading manipulator 13 running between the conveying mechanism 7, the workpiece turning mechanism 8, the fourth machine tool 5 and the discharge conveyor belt 11. A workpiece translation conveyor belt 26 is provided between the first machine tool 2 and the second machine tool 3. The conveying mechanism 7 includes a conveyor belt.

[0027] Through the conveying mechanism and the first loading and unloading robot 9, the second loading and unloading robot 10, the third loading and unloading robot 12, and the fourth loading and unloading robot 13, the workpiece is sequentially transferred between each process, and the third machine tool 4 and the fourth machine tool 5 can perform the processing of the fourth process in parallel, effectively ensuring the processing efficiency.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the first loading and unloading robot 9, the second loading and unloading robot 10, the third loading and unloading robot 12, and the fourth loading and unloading robot 13 all include a truss 14 and a mounting seat 15, and a horizontal moving mechanism and a vertical moving mechanism are provided between the mounting seat 15 and the truss 14. The horizontal moving mechanism and the vertical moving mechanism can adopt the existing technology, and their specific structures are not repeated here. A robot mounting seat 16 is rotatably mounted on the mounting seat 15, and the mounting surface of the mounting seat 15 is 45 degrees to the horizontal plane. A robot mounting seat 16 is rotatably mounted on the mounting surface, and a rotating drive mechanism is provided between the manipulator mounting seat 16 and the mounting seat 15. The rotating drive mechanism can adopt a rotating cylinder, etc. A loading clamp 17 and a unloading clamp 18 are installed on the manipulator mounting seat, and the angle between the loading clamp 17 and the unloading clamp 18 is 90 degrees. Since the mounting surface of the mounting seat 15 is 45 degrees to the horizontal plane, the rotation drive mechanism can drive the manipulator mounting seat 16 to rotate relative to the mounting seat 15, thereby realizing the switching of the loading clamp 17 and the unloading clamp 18. In this way, when unloading and loading, the unloading clamp 18 clamps the workpiece that has been processed in the corresponding process on the machine tool, and then transports the processed workpiece along the truss 14, and the loading clamp 17 clamps the workpiece that has not been processed in this process.

The processed workpiece is clamped onto the corresponding machine tool. For example, after the unloading jaw 18 of the first loading and unloading robot 9 clamps the workpiece processed by the first machine tool, the robot mounting seat 16 can be driven to rotate relative to the mounting seat 15 through the rotating drive mechanism, thereby realizing the switching of the loading jaw 17 and the unloading jaw 18. The loading jaw 17 clamps the workpiece that has not been processed in the first process onto the first machine tool 2, and then the first loading and unloading robot 9 transports the workpiece that has completed the first process along the truss 14 to the workpiece translation conveyor belt 26, so as to facilitate the second loading and unloading robot 10 to clamp the workpiece, and then the first loading and unloading robot 9 moves along the truss 14 to clamp the unprocessed workpiece on the loading conveyor belt 6, so as to repeat the above operation.
