Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hub processing and conveying, and particularly relates to an intelligent suspension conveying system for automobile hub processing. BACKGROUND

[0002] After the automobile hub is cast, it needs to be transported to the next processing position, such as drilling, chamfering and deburring.

[0003] In the existing automobile hub processing, the hub is lifted by a lifting appliance and then transported to a processing machine tool by manual adjustment and positioning. The hub is usually heavy, and frequent handling can easily cause worker fatigue and reduce work speed. Manual operation is easily affected by the state of the worker, and it is difficult to ensure continuous and stable production rhythm. Manual handling is slow and requires additional time for adjustment and positioning. Manual handling can easily cause the hub to be scratched and damaged, resulting in surface quality defects. When the hub is placed in the processing center, it may deviate from the fixture reference, causing processing errors.

[0004] Most of the existing suspension conveying systems for automobile parts still need manual loading and unloading. For example, in the patent CN 117963450 B, a clamping mechanism is used to control the overall lifting or lowering of the suspension frame. The crossbar is rotated downward to the vertical state under the gravity of the hub, and the height of the hub is lowered to facilitate the removal of the hub. However, in actual production and processing of the hub, there is a horizontal safety distance between the entire suspension conveying line and the machine tool or other processing equipment to provide space for personnel access or operation. This makes it necessary to use manpower or a manual lifting machine to move the hub to the machine tool or processing equipment for clamping before processing (such as turning, milling, boring, spraying, welding or detection) can be performed. The space left for personnel access or operation is prone to the deficiencies caused by the above-mentioned handling. SUMMARY
