Description

Technical Field

[0001] The utility model belongs to the technical field of tire production, and particularly relates to a dynamic balancing positioning wheel rim picking and transferring device. Background Art

[0002] The rim, commonly known as the wheel rim, is a component that mounts and supports the tire around the wheel. There are two common forms of rims: deep groove rims and flat bottom rims; in addition, there are split rims, semi-deep groove rims, deep groove wide rims, flat bottom wide rims, and full bevel bottom wheels. Wheel dynamic balancing refers to adjusting the weight distribution of the tire and rim to achieve an ideal state. This concept is mainly applied to the tire system of vehicles such as cars and motorcycles to ensure that the vehicle maintains stability and safety during driving. When the wheel is rotating, due to factors such as manufacturing errors and material inhomogeneity, different parts of the wheel may generate different centrifugal forces. This imbalance will cause wheel vibration, affect the stability and comfort of the vehicle, and also increase tire wear and fuel consumption. In order to eliminate these adverse effects, the wheel needs to be dynamically balanced. The dynamic balancing process involves applying a force opposite to the centrifugal force to the wheel to offset the centrifugal force generated by the imbalance. In this way, the wheel reaches a dynamic balance state when rotating.

[0003] The Chinese utility model application number 201922425702.5 discloses a wheel dynamic balance detection line, including an automatic loading roller, which is used to drive the workpiece to move forward to the material collection position; a material transfer device, which transfers the workpiece at the material collection position to the fixture assembly for clamping and detection through a manipulator material collection mechanism, and transfers the detected workpiece to the automatic unloading roller; a fixture assembly, which is used to clamp the workpiece and drive the workpiece to rotate; a detection device, which is connected to the fixture assembly through a leaf spring, and when the workpiece rotates at high speed with the fixture assembly, the vibration frequency of the workpiece is recorded; an automatic unloading roller, which is used to drive the workpiece after detection to move forward; the qualified workpiece directly passes through the automatic unloading roller, and the unqualified workpiece is removed to the removal roller through a sorting device. This scheme is suitable for the dynamic balance detection of the wheel assembly, but does not mention the combined positioning process of the two positioning rims before the dynamic balance detection. Different specifications of tires use different rims, which are currently replaced manually. Because the rims are heavy and inconvenient to operate, they often require the cooperation of two to three people, but there are safety hazards, low work efficiency, and high labor intensity for workers.
