Description

Technical Field

[0001] The utility model relates to the field of wheel hub clamping tools, in particular to a turning clamping tool for automobile aluminum alloy wheel hubs. Background Technique

[0002] For turning of rotary parts, three-jaw chucks and four-jaw chucks are usually used for processing. When processing automobile aluminum alloy wheel hubs, it is necessary to process heat dissipation holes on their surfaces, and specific processing fixtures are required to fix them to facilitate automated production. After retrieval, a tool for ensuring the roundness of the outer circle turning of an automobile wheel hub disclosed in the patent application No. CN202022815445.9 includes a processing turntable. A base is slidably arranged on the left surface of the processing turntable. Three bases are arranged equidistantly along the circumference. Driving cylinders are connected to the outer sides of the bases. Claw jaws are arranged inside the bases. The claw jaws are arc-shaped. A groove is arranged in the middle of the inner side of the claw jaws. The groove divides the inner side surface of the claw jaws into two symmetrical bosses. By arranging three claw jaws, and each claw jaw is divided into two stress points through the groove, the three-jaw six-point structure is adopted to clamp the wheel hub, so that the processing state tends to be circular to the greatest extent and the quality of the product is guaranteed. However, the above description still has the following defects in actual use: This turning clamping tool is not convenient to adjust the angle after clamping and fixing the aluminum alloy wheel hub, so that the clamping structure does not adapt to the window inclination angle of the aluminum alloy wheel hub itself, and thus appropriate and accurate heat dissipation hole processing cannot be carried out. Therefore, it is necessary to design a practical and adjustable turning clamping tool for automobile aluminum alloy wheel hubs. Summary of the Utility Model
