[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] (1) Through the adaptive centering and fixing device, using the radial adjustment screw, pipe fixing clamp and scale lines and other components, it can be accurately adjusted according to the diameter of the pipe to be milled with the inner ring groove, so that the moving distance of each pipe fixing clamp is consistent, thereby accurately achieving center positioning and fixing. This precise centering function can greatly improve the accuracy of milling and ensure that the inner ring groove milled meets the strict size and shape requirements;

[0018] (2) It can be adjusted according to pipes of different diameters and can adapt to the processing of pipes of various specifications. This feature improves the versatility of the device and reduces the cost of equipping enterprises with multiple different fixing devices due to different pipe specifications;

[0019] (3) The self-rotation and revolution transmission device in the device can realize the self-rotation and revolution of the driving gear. During the milling process, the self-rotation of the driving gear drives the drill rod to rotate and mill the pipe fittings. At the same time, it revolves along the central fixed gear disc, driving the supporting turntable to rotate around the bearing column, thereby enabling the adjustable milling device to perform a circular inner ring groove milling operation. This combination of self-rotation and revolution can realize all-round milling of the inner ring groove of the pipe fitting, ensuring the integrity and uniformity of the milling;

[0020] (4) With the help of the lifting adjustment device, the bearing plate, bearing column and other components are lifted and lowered by rotating the lifting adjustment screw, thereby realizing the height adjustment of the chip self-priming milling device. The milling device can be accurately adjusted to the inner ring groove of the pipe to be milled, and the milling position can be accurately controlled. This precise adjustment function helps to improve the accuracy of milling and reduce processing errors;

[0021] (5) The adsorption wheel, adsorption fan and other components in the debris self-priming milling device can adsorb and collect the debris generated by milling during the milling process. The debris is adsorbed into the sleeve ring and falls into the collection box through the adsorption tube, which effectively prevents the debris from scattering everywhere, keeps the working environment clean, and reduces the intensity of cleaning work;

[0022] (6) Timely collection of debris can prevent debris from entering other parts of the equipment, prevent equipment failure due to debris accumulation, and extend the service life of the equipment. At the same time, it also avoids possible damage to operators caused by debris and improves work safety;

[0023] (7) The clip-on expansion plate in the elastic adaptive fitting can be adaptively expanded and contracted according to the size of the inner wall of the pipe fitting, and is sealed and fitted under the action of the rubber edge, which ensures that the milling device fits tightly with the inner wall of the pipe fitting, especially on pipe fittings of different sizes. This tight fit not only helps the stability of the milling operation, but also prevents the debris generated during milling from falling from the fitting, further improving the efficiency of debris collection and ensuring the cleanliness of the milling environment.
