DEVICE FOR QUICK FASTENING OF A WHEEL ON A BALANCING MACHINE Russian patent published in 2022 - IPC G01M1/04 

FIELD: balancing equipment.

SUBSTANCE: invention relates to balancing equipment and can be used for quick fastening of a wheel on the shaft of a balancing machine. A device for quick fastening of a wheel on a balancing machine is claimed, comprising a hollow shaft mounted for rotation horizontally on bearings, a clamping flange for centering a balanced wheel located at the first end of the hollow shaft, a secondary shaft acting as a thrust and installed to freely perform translational movement inside a hollow shaft, a locking element for fixing the wheel on the clamping flange, a pneumatic cylinder for performing a translational movement towards the clamping flange to release the locking element. According to the invention, the pneumatic cylinder is made rotating, one-sided without a rear cover and is fixed on the drive pulley of the spindle assembly of the balancing machine. An additional double-sided pneumatic cylinder is installed coaxially with the spindle unit, on the rod of which the nipple of the first part of the quick-release coupling is fixed, to which the working pressure is supplied through the articulated nipple. At the same time, the fitting of the second part of the quick-release connection is fixed on the rod of the rotating pneumatic cylinder.

EFFECT: improving the accuracy of the balancing machine as a whole due to the fact that the rotating structure of the quick clamping mechanism of the wheel rotates with the wheel in the process of measuring the imbalance of the wheel. This minimizes the rotating mass of the structure and its balance.
