Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a clamp for processing wheel nuts. Background Art

[0002] In the automobile manufacturing and maintenance industry, the processing of wheel nuts is an indispensable key link. As an important fastener, the quality and processing accuracy of nuts directly affect the driving safety and stability of the car. Therefore, the processing requirements for wheel nuts are extremely high, and accurate, efficient and stable fixtures are needed to support the processing process. The Chinese utility model patent, authorization announcement number "CN219725312U" discloses a fixture for nut processing. When in use, the third screw rod is rotated to move left and right. When the third screw rod moves to the left, it will press against the bottom end of the slide rod and gradually push the slide rod outward, and the nut to be processed is placed on the ring sleeve. The three outward-moving slide rods push the rubber pad and make it tightly against the inner side of the nut to be processed. The position of the second clamp is adjusted to clamp the nut to be processed from the side. When the edge of the nut is cut, it will not deviate from the center even after the nut is rotated, and it has good stability.

[0003] During use of the above technical solution, the wheel nut is not installed on the fixture quickly enough, and the outside of the nut needs to be clamped when fixing the nut, which limits the processing of the outside of the nut and makes it inconvenient to process the outer surface of the nut, resulting in low processing efficiency of the nut. Therefore, we propose a fixture for processing wheel nuts. Utility Model Content
