[0001] This invention relates to the field of CNC vertical grinding centers, specifically to a high-temperature early warning and cooling window frame linkage opening and closing structure and a CNC vertical grinding center. Background Technology

[0002] A CNC vertical grinding center is a type of CNC machine tool that can perform grinding operations with high efficiency. It controls the movement of the grinding head through a computer program to achieve high-precision grinding. CNC vertical grinding centers are generally used for grinding large flanges or gears. In the existing technology, when grinding large flanges or gears, CNC vertical grinding centers are generally used in a closed operation to prevent machining debris from splashing out.

[0003] However, when traditional CNC vertical grinding centers operate in a closed environment, the milling of large flanges or gears by the machining equipment generally causes the temperature inside the CNC vertical grinding center to rise continuously. When the temperature is too high, it may damage the parts inside the machining equipment, thereby reducing the service life of the CNC vertical grinding center.

[0004] Therefore, we need a high-temperature warning and cooling window frame linkage opening and closing structure and a CNC vertical grinding center to solve the problem of excessive internal temperature causing damage to internal components in traditional CNC vertical grinding centers during closed operation, which can give CNC vertical grinding centers a longer service life.

Finally, the warning device starts the exhaust motor, thereby opening the vertical grinding center. The high-temperature air inside the vertical grinding center body is drawn out and then cooled air is introduced into the vertical grinding center body through the filter plate, thereby cooling the processing module and the components being processed. This cooling method is convenient, quick, and saves time and effort. It also prevents damage to the components inside the processing module due to excessive internal temperature of the vertical grinding center body, thus improving the service life of the vertical grinding center body. At the same time, it solves the problem of excessive internal temperature damaging the components inside the device when the traditional CNC vertical grinding center is in closed operation, which can give the CNC vertical grinding center a longer service life.

The drive groove 31 opened on the front surface of the drive seat 30 has a column structure. The drive insert 32 is fixedly connected to the outer side of the drive seat 30. When the rotating plate 8 is to be rotated inward, the drive motor 29 is started. The drive motor 29 drives the bidirectional threaded rod 28 to rotate. The bidirectional threaded rod 28 drives the drive seat 30 to move towards both ends of the sliding column 27 through the helical transmission with the drive seat 30. The driven shaft 18 in the drive groove 31 also moves with the drive seat 30 in the guide rail 19 until the moving plate 17 moves with the driven shaft 18 and is completely retracted into the receiving groove 16. At this time, the drive insert 32 is inserted into the driven groove 24 with the drive seat 30 and pushes the lifting column 23 upward.

[0027] Example 3:

[0028] Please see Figures 1-6Based on Embodiment 2, in order to rotate the rotating plate 8 to open the air inlets on both sides of the vertical grinding center body 1, a hinge pressure plate 11 is provided.

When the limiting pin 25 is completely disengaged from the limiting slot 10, the hinge pressure plate 11 drives the rotating plate 8 to rotate inward under the action of the compression spring 13. At this time, the driven shaft 18 also rotates with the rotating plate 8 and is disengaged from the drive groove 31 and slides into the outermost end of the guide rail 19, thereby opening the air inlets on both sides of the vertical grinding center body 1. This operation method is convenient and quick, saving time and effort. At the same time, it solves the problem that the internal temperature of the traditional CNC vertical grinding center is too high during closed operation, which causes damage to the internal parts of the device. It can make the CNC vertical grinding center have a longer service life.

[0029] Example 4:

[0030] Please see Figures 1-6 In order to cool down the body 1 of the vertical grinding center, based on the third embodiment, an early warning device body 33 is provided. The early warning device body 33 is electrically connected to the exhaust fan motor 4 and the processing module 34. The exhaust fan motor 4 is fixedly connected to the front surface of the exhaust fan 3, the exhaust fan 3 is fixedly connected to the front surface of the exhaust duct 2, and the exhaust fan 5 is fixedly connected to the end of the exhaust fan motor 4. The warning device body 33 is electrically connected to the drive motor 29. When the temperature inside the vertical grinding center body 1 is too high and triggers the warning device body 33, the warning device body 33 first sends a command to the processing module 34 to shut it down. Then, it sends a command to the drive motor 29 to start the drive motor 29 and open the air inlet of the vertical grinding center body 1. Finally, the warning device body 33 sends a command to the exhaust fan motor 4 to start the exhaust fan motor 4. The exhaust fan motor 4 drives the exhaust fan 5 to rotate, thereby drawing the high-temperature air inside the vertical grinding center body 1 out through the exhaust fan 3 and the exhaust duct 2, and drawing low-temperature air into the vertical grinding center body 1 from outside the filter plate 7. The filter plate 7 can prevent debris from being brought into the vertical grinding center body 1. When the warning device body 33 does not... When the alarm sounds again, the reset pneumatic lever 15 is activated. The reset pneumatic lever 15 pushes the rotating plate 8 into the window frame 6. At the same time, the driven shaft 18 rotates back into the drive slot 31 along with the rotating plate 8. At this time, the drive motor 29 is activated to make the bidirectional threaded rod 28 rotate in the opposite direction to drive the drive seat 30 to move inward, thereby moving the moving plate 17 inward until the air inlet is closed. During the process of the drive plug 32 disengaging from the driven slot 24, the limiting plug 25 is reinserted into the limiting slot 10 under the action of the reset spring 22 to limit the rotation of the rotating plate 8. This sealing method is simple to operate, saves time and effort, and solves the problem of excessive internal temperature causing damage to the internal parts of the device when the traditional CNC vertical grinding center is closed. It can give the CNC vertical grinding center a longer service life.

[0031] Example 5:

The drive motor 29 causes the bidirectional threaded rod 28 and the drive seat 30 to drive the driven shaft 18 and the moving plate 17 inside the drive seat 30 to move into the receiving groove 16. When the drive plug 32 is inserted into the driven slot 24 and the limiting plug 25 is pushed out of the limiting slot 10, the hinge plate 11 drives the rotating plate 8 to rotate under the action of the compression spring 13, thereby opening the air inlet; Finally, the warning device 33 starts the exhaust fan 4 to carry out the high-temperature air inside the vertical grinding center body 1, and brings in low-temperature air from outside the filter plate 7 into the vertical grinding center body 1, thereby cooling the processing module 34 and the components being processed.
