Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile hub detection, and in particular to a rapid positioning and detection device for automobile hub. BACKGROUND

[0002] In the field of automobile hub manufacturing and quality detection, accurate positioning and rapid detection of various specifications of automobile hubs are key links to ensure product quality and production efficiency. Currently, the positioning and detection of such hubs are usually based on fixed workbenches.

[0003] The support structure of a conventional workbench is usually fixed or has a limited adjustment range. This rigid design is difficult to adapt to different specifications of hubs, resulting in the inability of the hub to be stably placed at the center detection reference position. Especially for large-size truck hubs, the mismatch between the support point and the back structure of the hub can cause tilting risk, limiting the versatility of the equipment. At the same time, there is usually a large static friction force between the workbench table (usually made of metal or hard composite material) and the bottom surface of the hub. After the operator or the mechanical hand initially places the hub on the workbench, additional physical effort or complex fine-tuning actions are often required to overcome this friction in order to accurately move the hub to the preset detection reference point or clamping position. This not only increases the operation difficulty and labor intensity, but also seriously slows down the positioning efficiency. Finally, to solve the problem of friction, some improved schemes embed a ball structure on the surface of the workbench. This design indeed effectively reduces the resistance of the hub moving on the table surface, making it easier to push. However, this simple ball structure has a key defect: it has no active or passive auxiliary positioning function. When the operator tries to push the hub to the target position or when the automatic clamping mechanism starts to act, the hub lacking effective limiting or guiding is prone to uncontrolled sliding or deviation on the ball. This "sliding" phenomenon not only greatly reduces the positioning accuracy, causing the detection reference to be misaligned, but also can cause the hub to be misaligned during clamping and even cause safety risks such as damage to the equipment or the hub, so the existing technology has great limitations.
