[0002] Three-jaw chucks and four-turn chucks are usually used for turning rotating parts. When machining automobile aluminum wheels, heat dissipation holes need to be machined on their surfaces, and specific machining fixtures need to be used to fix them in order to realize automated production. After searching, the application number CN202022815445.9 disclosed a tooling for ensuring the roundness of the outer ring of the automobile wheel hub. It records that it includes a machining turntable, and a base is provided on the sliding surface of the left side of the machining turntable. The base is equidistantly arranged with three driving cylinders along the circumference. The outside of the base is connected to a clamping claw, and a groove is provided in the middle of the inner side of the clamping claw. The groove separates the inner side of the clamping claw to form two symmetrical bosses. By setting three clamps Claws, and two force points are formed by separating the grooves in each clamping jaw, and the wheel hub is clamped with a three-claw six-point structure, so that the processing state tends to be circular to the greatest extent, ensuring the quality of the product. However, the above description still has the following defects in actual use: the milling fixture is not convenient for adjusting the angle after clamping and fixing the commercial vehicle aluminum wheel hub, so that the clamping structure is not suitable for the window inclination angle of the aluminum wheel hub's own product structure, thereby unable to perform appropriate and accurate heat dissipation hole processing, and the clamping height cannot be adjusted during the processing, which limits the use of the fixture. Therefore, it is necessary to design a practical and adjustable automobile aluminum wheel hub turning clamping tooling. Utility Model Content
