[0016] The beneficial effects achieved by the present invention with the above structure are as follows: (1) Through the adaptive centering and fixing device, by using components such as the radial adjustment screw, pipe fitting fixing clamp, and scale line, it can be precisely adjusted according to the diameter of the pipe fitting with an inner ring groove to be milled, so that the moving distances of each pipe fitting fixing clamp are consistent, thereby accurately achieving central positioning and fixing. This precise centering function can greatly improve the milling accuracy and ensure that the milled inner ring groove meets strict dimensional and shape requirements. (2) It can be adjusted according to pipe fittings of different diameters and can adapt to the processing of various specifications of pipe fittings. This feature improves the versatility of the device and reduces the cost for enterprises to equip multiple different fixing devices due to different pipe fitting specifications. (3) The self-rotation and revolution transmission device in the device can achieve 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 for milling the pipe fitting, and at the same time, it revolves along the central fixed gear disk, driving the supporting turntable to rotate around the load-bearing column, thereby enabling the adjustable milling device to perform a circumferential inner ring groove milling operation. This combination of self-rotation and revolution can achieve all-round milling of the inner ring groove of the pipe fitting, ensuring the integrity and uniformity of the milling. (4) With the help of the lifting adjustment device, by rotating the lifting adjustment screw to drive the lifting of components such as the load-bearing plate and load-bearing column, the height adjustment of the chip self-aspiration milling device can be achieved, and the milling device can be accurately adjusted to the inner ring groove of the pipe fitting to be milled, precisely controlling the milling position. This precise adjustment function helps to improve the accuracy of milling and reduce processing errors. (5) Components such as the adsorption wheel and adsorption fan in the chip self-aspiration milling device can adsorb and collect the chips generated during milling. The chips are adsorbed into the socket ring and fall into the collection box through the adsorption pipe. This effectively prevents the chips from scattering everywhere, keeps the working environment clean, and reduces the intensity of cleaning work. (6) Timely collection of chips can prevent the chips from entering other components of the equipment, prevent equipment failures caused by chip accumulation, extend the service life of the equipment, and at the same time, avoid potential injuries to operators caused by chips, improving work safety. (7) The clamping telescopic plate in the elastic adaptive fitting can adaptively expand and contract according to the size of the inner wall of the pipe fitting and is hermetically fitted under the action of the rubber edge. This ensures the tight fit between the milling device and the inner wall of the pipe fitting, especially achieving a good fit effect on pipe fittings of different sizes. This tight fit not only helps to improve the stability of the milling operation but also prevents the chips generated during milling from falling from the fitting, further improving the chip collection efficiency and ensuring the cleanliness of the milling environment.
