Description

Technical Field

[0001] This utility model relates to the field of wheel equipment technology, and in particular to a hook-type wheel dynamic balancing correction machine. Background Technology

[0002] A wheel is a rigid wheel that fixes the inner edge of the tire, supports the tire, and shares the load with the tire. It is usually composed of components such as the tire, rim, and valve. The reason for performing dynamic balancing on the wheel and installing counterweights is that, due to manufacturing processes, the mass distribution of the wheel components cannot be completely uniform. When the wheel rotates at high speed, an imbalance will occur, which will cause phenomena such as wheel vibration and steering wheel vibration during vehicle operation. This not only reduces driving comfort but also accelerates the wear of the tires and suspension system and may even affect driving safety. Therefore, dynamic balancing is necessary by adding counterweights (balance blocks) to the wheel to correct the balance of the various edges of the wheel, ensuring that the wheel maintains dynamic balance when rotating at high speed, thereby improving the vehicle's driving stability and safety and extending the service life of the tires and related vehicle components.

[0003] When correcting wheel dynamic balancing, the wheel needs to be installed on a dynamic balancing device. After measuring any abnormalities in the dynamic balance, the dynamic balancing blocks are clamped into the designated positions inside the wheel hub according to the measurement data for correction. In the prior art, the dynamic balancing blocks are generally installed manually, and there is a lack of automated installation equipment, which wastes manpower and resources. Therefore, this utility model proposes a hook-type wheel dynamic balancing correction machine to solve the problems existing in the prior art. Utility Model Content

The upper and lower robotic arms drive the clamping and installation assembly to clamp the hook-type balance block to the position provided by the previous workstation and install it. This fully automates the process, saving labor and improving the automation of the production line.
