Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Please refer to Figures 1-5 An embodiment of the present application is: a part processing combined numerical control machine tool, comprising: a main machine tool 1, a numerical control module 2, the numerical control module 2 is arranged on the inner wall of the main machine tool 1; a sliding door 3, the sliding door 3 is slidingly installed on the inner wall of the main machine tool 1, and the sliding door 3 is driven by a motor; a rotating system 4, the rotating system 4 is arranged on the inner wall of the main machine tool 1, and the rotating system 4 is used to drive the part to rotate; a driving device 5 is arranged at the bottom of the inner wall of the main machine tool 1, an electric telescopic rod 6 is fixedly installed at the output end of the driving device 5, a tool changer is arranged at the output end of the electric telescopic rod 6, a roller 7 is rotatably installed on one side of the sliding door 3 close to the rotating system 4, a trapezoidal plate 8 is slidingly installed on the inner wall of the main machine tool 1, the roller 7 is used to push the trapezoidal plate 8 to move upward, a baffle 9 is fixedly installed at the bottom of the trapezoidal plate 8, a fixed plate 10 is fixedly installed on the inner wall of the main machine tool 1, a pressing sensor 11 is arranged at the bottom of the fixed plate 10, and the pressing sensor 11 is used to detect whether the sliding door 3 is completely closed, a sealing device and a foreign matter removal device are arranged in the main machine tool 1, so as to prevent iron filings in the machining process from entering the gap between the sliding door 3 and the main machine tool 1, which may cause the sliding door 3 to be stuck or appear to be stuck, which will affect the production efficiency, and even may cause the machine tool to be unable to normally operate, and need to be stopped for maintenance.

[0031] A first spring is provided between the main machine tool 1 and the trapezoidal plate 8. When the trapezoidal plate 8 is separated from the roller 7, the elastic force of the first spring will drive the trapezoidal plate 8 to reset. The press-type sensor 11 is located below the trapezoidal plate 8. The press-type sensor 11 is deactivated by contact between the trapezoidal plate 8 and the press-type sensor 11.

[0032] In this embodiment, the part is placed inside the rotating system 4 and locked in place. Then, by controlling the CNC module 2, the CNC module 2 will start the motor to close the sliding door 3. Subsequently, the rotating system 4 will drive the part to rotate. The part is processed by the drive device 5 moving laterally in conjunction with the electric telescopic rod 6 and the tool exchange device. The tool can be switched back and forth to process more precise and complex parts, improving the practicality of the equipment.

[0033] Meanwhile, as the sliding door 3 moves toward the drive device 5, it will drive the roller 7 to move toward the drive device 5. The roller 7 will contact the inclined surface of the trapezoidal plate 8 as it moves toward the drive device 5. The roller 7 will squeeze the trapezoidal plate 8 to move upward. The upward movement of the trapezoidal plate 8 will drive the baffle 9 to move upward. The upward movement of the baffle 9 will block the gap between the sliding door 3 and the main machine tool 1, preventing iron filings from entering the gap between the sliding door 3 and the main machine tool 1 during processing. This may cause the sliding door 3 to jam or become stuck. This situation will affect production efficiency and may even cause the machine tool to malfunction and require shutdown for maintenance.

[0034] Meanwhile, as the trapezoidal plate 8 moves upward, it will come into contact with the press sensor 11. The press sensor 11 can detect whether the sliding door 3 is completely closed.

[0042] The L-shaped limiting plate 136 is slidably installed on the inner wall of the main machine tool 1, a recycling groove is formed in the main machine tool 1, and the recycling frame 137 is slidably installed on the inner wall of the recycling groove. The bottom of the recycling frame 137 is provided with a filter screen 138, and a groove is formed in the top of the recycling frame 137. During the process of recycling iron filings, the user cannot take out the recycling frame 137, which affects the recycling of the iron filings. The cooling liquid can flow out through the filter screen 138, preventing the mixing of the iron filings and the cooling liquid in the recycling frame 137, which affects the recycling and reuse of the iron filings and the cooling liquid.
