The chip removal port 7 passes through the machine cover 1 and is below the indicator light 6; The sliding door 2, the indicator light 6, the workbench assembly 8, the tool magazine assembly 9, the cooling fan assembly 10 and the control center 4 are electrically connected; Embodiment 1: Grinding method of turning and milling compound lathe Specifically, the staff compiles the processing program in the control center 4, opens the sliding door 2, the sliding door 2 slides on the machine tool base 3, opens the opening of the clamping chuck 33, places the workpiece to be processed at the opening of the clamping chuck 33, then tightens the clamping chuck 33 to clamp one end of the workpiece, controls the spindle bottom plate 39 to approach the rotary chuck 32 through the control center 4, and the spindle bottom plate 39 slides on the workbench base 31, while driving the bottom plate 38 to slide on the workbench base 31, and when the other end of the workpiece presses against the rotary chuck 32, stops the movement of the spindle bottom plate 39 through the control center 4. The staff starts the spindle box 30, adjusts the position of the spindle box 30 to align the workpiece, and when the tool 20 on the spindle box 30 hits the workpiece, the data is recorded in the control center 4, the spindle box 30 is removed, the rotary chuck 32 and the clamping chuck 33 are started, and the workpiece rotates with the rotation of the rotary chuck 32 and the clamping chuck 33. Then the turning tool is used to align the workpiece, and the bottom plate 38 moves on the workbench base 31, driving the tool holder 37 to move left and right, and the base 36 moves on the top of the tool holder 37, driving the tool holder 37 to move back and forth. When the turning tool on the tool holder 37 hits the workpiece, it is recorded in the control center 4, the sliding door 2 is closed, and the processing is started through the control center 4, then the workpiece in the machine tool starts to be processed. During machining, in order to meet the needs of workpiece machining technology, it is often necessary to replace a new tool 20 in the spindle box 30. When the spindle box 30 stops rotating, one end of the robot arm 23 takes out the tool 20 to be machined from the tool slot 19, and the robot arm 23 moves to the rear of the fixed end 16 along the guide rod 22. The length of the robot arm 23 is extended by hydraulic control, and the other end of the robot arm 23 is extended to clamp the tool 20 on the spindle box 30. The tool 20 on the spindle box 30 is taken down, the robot arm 23 is rotated, and the tool 20 taken from the tool slot 19 is put in. Then the robot arm 23 is retracted, and the robot arm 23 moves the fixed end 16 along the guide rod 22. In front of the tool 20, the end of the growing robot arm 23 holding the tool 20 is placed in the cleaning tank 27, and the tool 20 is immersed in the special cleaning liquid. The immersion time is set to t, and t is a constant value. When the time t is reached, the robot arm 23 is retracted, and the tool 20 is lifted above the cleaning tank 27. The cooling fan assembly 10 blows air on the tool 20. After the tool 20 is completely dried, the robot arm 23 puts the tool 20 in front of the nozzle 25, and the nozzle 25 is started through the control center 4. The nozzle 25 sprays the anti-rust oil in the oil tank 24 on the tool 20, and then the tool 20 is placed on the empty tool slot 19 through the robot arm 23. The device is provided with a cleaning pool 27, so that the tool 20 just replaced from the spindle box 30 can be cleaned immediately, thereby increasing the service life of the tool 20 and saving the manpower to disassemble the tool 20 for cleaning. The whole process is very convenient and does not require human intervention.

[0018] In the second embodiment, when the tool 20 is replaced, the temperature of the tool 20 replaced by the spindle box 30 will continue to remain high and the temperature will decrease slowly. Specifically, when the robot arm 23 clamps the tool 20, the temperature sensor transmits the temperature of the tool 20 to the control center 4, and sets the temperature of the normal tool 20 after cleaning for t time to a, and a is a constant value. After the tool 20 is cleaned for t time, the temperature sensor transmits the recorded data to the control center 4, and the temperature displayed by the control center 4 is b. When b>a, it is considered that the tool 20 is normally worn. The robot arm 23 is controlled to put the tool 20 into the cleaning tank 27 again, and the robot arm 23 is swung left and right at the same time, so as to drive the tool 20 to shake in the cleaning tank 27, accelerate the flow of the cleaning liquid, and reduce the temperature of the tool 20 through the temperature of the cleaning liquid. After reaching t time, the tool 20 that has been immersed for the second time is taken out and drained. The robot arm 23 detects the temperature of the clamped workpiece. At this time, b does not exceed a. After spraying anti-rust oil, it is placed in the empty tool groove 19, indicating that the tool 20 is normally worn, resulting in a smaller volume and slow heat dissipation. After cooling again, the tool 20 can be cooled down without affecting the use of the machine tool. After the tool 20 is taken out and drained after the second immersion, the robot arm 23 detects the temperature of the clamped tool 20. At this time, b is still greater than a, indicating that cooling needs to be strengthened. The robot arm 23 sends the tool 20 to the cooling fan assembly 10 for blowing. The time is set to T, and T is a constant value. After reaching T time, b<a, the robot arm 23 is sprayed with anti-rust oil and put into the empty tool groove 19, indicating that the tool 20 is also normally worn and only needs to strengthen the cooling time. At the same time, the staff needs to optimize the processing trajectory of the tool 20 in the control center, reduce the cutting pressure, reduce the friction heat generation, and thus reduce the overheating of the tool 20; After reaching T time, b is still greater than a. At this moment, the staff needs to open the hood 1 on one side of the tool magazine assembly 9 to judge the appearance of the tool 20. According to the staff's experience, if the tool 20 has no obvious damage, it means that the material of the tool 20 is not resistant to high temperatures. When processing again, replace the high-quality tool 20 to improve the processing efficiency. The tool 20 is applied with anti-rust oil through the mechanical arm 23 and placed in the empty tool groove 19, and the position of the tool groove 19 is recorded. Before using the tool 20 again, the mechanical arm 23 will perform temperature detection on the tool 20 in the tool groove 19. If b does not exceed a, the tool 20 can be used. If b exceeds a, a new tool 20 needs to be replaced. After observation by the staff, if the tool 20 is severely worn, the tool 20 needs to be scrapped and suspended from use. The device records the temperature of the tool 20 by installing a temperature sensor on the robot arm 23. Based on the temperature of the tool 20, the control center 4 can determine whether the tool 20 needs to be replaced or the processing route needs to be optimized, thereby improving the processing efficiency and preventing accidents of the tool 20 from causing certain losses to the processed workpiece.

[0019] Embodiment 3: When the tool 20 is in the cleaning fluid, the cleaning fluid has a low temperature, which will take away the heat of the tool 20 and increase the temperature of the cleaning fluid. When the temperature of the cleaning fluid increases, it will have a certain impact on the cooling of the next workpiece. Specifically, the time interval from when the tool 20 comes out of the cleaning pool 27 to when the next tool 20 is put in is set to x, where x is a constant value. When the previous tool 20 comes out of the cleaning pool 27, the control center 4 records the time. When the next tool 20 arrives above the cleaning pool and is ready to be cleaned, the control center 4 stops recording the time and sets the time to y. The y time is transmitted to the control center 4 for comparison with x. When y exceeds x, the tool 20 is operated according to the second embodiment. When y does not exceed x, it means that the time interval between two cooling of the tool 20 is short, and the temperature of the cleaning liquid in the cleaning pool 27 needs to be detected. The normal cleaning liquid temperature is set to n. When y does not exceed x, the robot arm 23 is rotated 180 degrees, and the end that does not clamp the tool 20 is extended into the cleaning liquid. At this time, the temperature sensor will record the temperature in the cleaning liquid, set the temperature as m, and transmit the recorded temperature to the control center 4 for comparison with n. If m does not exceed n, the robot arm 23 is retracted and rotated 180 degrees again, and the end that extends and clamps the tool 20 enters the cleaning tank 27 for cooling and cleaning. If m exceeds n, the cooling fan assembly 10 is turned on to accelerate the cooling of the cleaning tank 27 to reduce the temperature of the coolant. When the temperature sensor of the robot arm 23 detects that m does not exceed n, the tool 20 can be cooled and cleaned. By setting up the robot arm 27, not only the temperature of the tool 20 can be detected, but also the temperature of the cleaning liquid can be detected, the recovery step of the tool 20 can be strictly controlled, the tool 20 can be better cleaned and cooled, and the probability of defects caused by the tool 20 on the workpiece can be reduced.
