Description

Technical Field

[0001] The utility model relates to the field of grinding wheels, in particular to a grinding wheel balancing and correction device. Background Art

[0002] Generally, grinding wheels with a diameter greater than 125 mm must be balanced so that the center of gravity of the grinding wheel coincides with its rotation axis. Unbalanced grinding wheels will vibrate when rotating at high speed, affecting the processing quality and machine tool accuracy. In severe cases, they will also cause machine damage and grinding wheel fragmentation. The main causes of imbalance are uneven density of different parts of the grinding wheel, asymmetric geometry, and eccentric installation. Therefore, the grinding wheel must be balanced before installation.

[0003] There are two types of grinding wheel balancing: static balancing and dynamic balancing. In general, only static balancing is required, but dynamic balancing is required for high-speed grinding (speed greater than 50m / s). The grinding wheel balancer is an accessory that must be equipped with a grinder. It can be used to statically balance the grinding wheel to achieve the purpose of using the grinding wheel correctly. A level gauge can also be added to detect the static balance of precision workpieces. When balancing, the grinding wheel is installed on the balancing mandrel, and then the grinding wheel with the mandrel installed is placed flat on the balancing guide rail of the grinding wheel balancing bracket. The grinding wheel will swing back and forth until the swing stops. The balanced grinding wheel can remain stationary at any position. If the grinding wheel is unbalanced, its heavier part will always turn to the bottom. At this time, the position of the balance block can be moved or balance blocks can be added on both sides of the grinding wheel to achieve balance. The existing grinding wheel balancer must be corrected before each use. The operation is complicated and the installation of the balance block is not convenient. Utility Model Content
