Description

Technical Field

[0001] The utility model relates to the technical field of dynamic balance testing, in particular to a dynamic balance testing device for an integral casting high-speed three-dimensional flow impeller. Background Art

[0002] The existing dynamic balancing test technology mostly uses workers to hold the three-dimensional flow impeller and place it on the mounting shaft for dynamic balancing test. However, this method cannot move large three-dimensional flow impellers when in use. For example, a Chinese patent discloses "a dynamic balancing test device" with the application number "CN202222796360.X". It uses the sliding of the support, drive seat and sliding seat on the slide rail to achieve position adjustment. When fixation is required, the fixing bolts are tightened to increase the friction between the fixing bolts and the base to achieve the fixation of the support, drive seat and sliding seat. However, its structure is simple, and workers cannot move large three-dimensional flow impellers. The rotating body drives the three-dimensional flow impeller, which is not fixed and is prone to danger. The rotating body increases the belt rotation, which is easily damaged at high speed and is unsafe. Utility Model Content
