Description

TECHNICAL FIELD

[0001] The utility model relates to automobile parts feeding technology field, concretely is a kind of automobile parts processing axle stem feeding structure. BACKGROUND

[0002] The main function of the axle stem feeding structure in the automobile parts processing process is to realize the automatic transmission of the axle stem between different stations, ensuring the efficiency, accuracy and continuity of the production process. Through the feeding structure, the staff can reduce manual handling, improve work efficiency, reduce the risk of errors and damage, and reduce fatigue caused by long-term handling of heavy objects. The feeding structure is composed of multiple key parts, including a feeding belt, a driving device, a support frame, a guide device and a sensor system. The feeding belt carries and transfers the axle stem. The driving device drives the movement of the feeding belt through an electric motor. The support frame provides stable support. The guide device ensures the stable flow of the axle stem. The sensor and control system accurately monitor and adjust the feeding process to ensure that the axle stem reaches the designated station accurately. In terms of working principle, the driving device makes the feeding belt move continuously, sending the axle stem from one station to another. The guide device and the support frame ensure the stability and smoothness of the axle stem during transportation. However, at present, in order to ensure that the axle stem workpieces on the feeding belt are not too crowded and stacked together, the staff needs to manually control the placement timing of the axle stem, i.e. the staff needs to continuously place the axle stem workpieces on the feeding belt. This means that the staff needs to continuously observe the conveyor belt and determine the placement timing of each axle stem workpiece. When a large number of axle stems need to be processed efficiently, manual operation will be particularly inefficient and difficult to meet the high-load production requirements. Moreover, during long-term work, manual control may be careless or inaccurate, causing improper placement of the axle stem, which may cause workpiece jamming, damage and other problems, thereby affecting the smooth operation of the production line.
