Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of milling machine tools, in particular to a large plane milling machine tool. BACKGROUND

[0002] Milling refers to the use of a rotating multi-blade cutter to cut a workpiece, and is a high-efficiency machining method. When milling, the cutter rotates, the workpiece moves, or the workpiece can also be fixed, but at this time the rotating cutter must also move.

[0003] Milling machines include horizontal milling machines or vertical milling machines, and also large gantry milling machines. It should be noted that during the machining of large plane workpieces (such as steel plates), deformation can also occur due to changes in stress, especially after cutting, stamping, and other processes, the internal stress state of the steel plate is complex, and deformation is prone to occur. At the same time, the cutting fluid piping of the milling machine can be blocked due to the accumulation of iron filings, grinding dust, and other impurities suspended in the cutting fluid over a long period of time. In addition, the milling cutter can be tilted to produce lateral force when cutting steel due to uneven wear of the cutter, asymmetric cutting edges, or because the cutter holder is deformed or the cutter is loose, causing the milling cutter to deviate on its own when running at high speed. These problems can cause a decrease in machining accuracy and can also cause excessive wear, deformation, or even breakage of the cutter, which can lead to processing accidents. SUMMARY

[0069] In summary, the working principle of the large plane milling machine tool provided in the embodiment of the present application is as follows:

[0070] When the milling machine tool 1 processes a large plane workpiece (such as a steel plate), the lifting carriage 2 moves vertically, the transverse carriage 3 moves horizontally, the cutter holder 5 drives the milling cutter 6 to rotate for milling, and the cutting fluid input pipe 11 transports the cutting fluid in the cutting fluid recovery tank 13 to the transfer detection box 701, and then the cutting fluid is transported to the cutting fluid spray head 10 through the cutting fluid output pipe 12 for spraying.

[0071] Further, if the cutting fluid recovery tank 13 is blocked or has other faults, the cutting fluid entering the transfer detection box 701 continuously decreases, and the liquid level of the cutting fluid continuously decreases. At this time, under the pulling force of the lifting spring 712, the floating lifting frame 706 slides downward in the vertical sliding groove 711, and the floating lifting frame 706 drives the floating sliding plate 703 to move downward. The floating sliding plate 703 drives the closed pipe 704 to move, so that when the liquid level in the transfer detection box 701 drops to a certain height, the closed pipe 704 is separated from the supplementary pipe 705, so that the cutting fluid in the supplementary pipe 705 flows out urgently, avoiding the problem that the milling cutter 6 suddenly loses the cutting fluid during processing, causing a processing accident. It should be noted that the floating lifting frame 706 is separated from the limiting jack 713 when it moves downward, and at this time, under the stretching force of the unlocking spring 714, the U-shaped plug-in frame 710 moves, and the U-shaped plug-in frame 710 is separated from the transfer plate 707. At this time, under the contraction force of the ascending spring 709, the transfer plate 707 drives the milling seat 4 to move upward, and the milling seat 4 drives the milling cutter 6 to move upward through the cutter holder 5, and timely separates from the steel plate, further avoiding the occurrence of a processing accident.

[0072] Further, it needs to be explained that when the shank 5 is deflected due to an accident, the shank 5 is pressed to move the shank contact rod 801 in the process of rotation, so that the shank contact rod 801 drives the offset push bracket 802 to move, the offset push bracket 802 drives the wedge-shaped push plate 803 to move, the wedge-shaped push plate 803 moves on the horizontal sliding rod 806 and makes the retracting spring 807 bear force, at the same time, the wedge-shaped push plate 803 moves to press the arc-shaped pressing plate 804 to move, so that the arc-shaped pressing plate 804 drives the floating lifting frame 706 to move, thereby the unlocking of the U-shaped plug-in frame 710 can be realized, the milling cutter 6 is moved upward, and the purpose of timely separating from the steel plate is achieved, the problem of unqualified processing or processing accident caused by the deflection of the milling cutter 6 is avoided;

[0073] Further, when the steel plate is processed, the rotating detection plate 902 is in contact with the steel plate by rotating, when the milling cutter 6 is lowered to mill, the rotating detection plate 902 is pressed to drive the follow-up mounting frame 901 to move, the follow-up mounting frame 901 moves vertically in the mounting frame 903 through the two vertical sliding frames 904, and the downward pressing spring 905 is stressed to contract, at the same time, the follow-up mounting frame 901 drives the adapter push bracket 911 to slide on the pressing bracket 912 to move, and when the milling seat 4 is transversely moved, the two vertical sliding frames 904 slide on the follow-up mounting frame 901. It needs to be explained that when the steel plate is continuously processed, if the steel plate is deformed, the rotating detection plate 902 is pushed to rotate in the process of moving by the protruding part, so that the rotating detection plate 902 drives the rotary shaft 907 to rotate, the rotary shaft 907 rotates in the reset mounting groove 908, and the reset torsional spring 909 is stressed, at the same time, the rotating detection plate 902 drives the rotating push rod 910 to rotate, so that the rotating push rod 910 drives the adapter push bracket 911 to move, the adapter push bracket 911 drives the pressing bracket 912 to move, the pressing bracket 912 moves horizontally in the limiting sliding groove 913 and the recovery spring 914 is stressed, thereby the pressing bracket 912 drives the floating lifting frame 706 to move, and the unlocking of the U-shaped plug-in frame 710 is also realized, so that the milling cutter 6 is moved upward to separate from the steel plate, and the problem of unqualified processing or processing accident caused by the deformation of the steel plate is avoided.

[0074] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
