Description

Technical Field

[0001] The utility model relates to the technical field of automobile blower balance detection, in particular to a dynamic balance detection platform for automobile blowers. Background Art

[0002] An automobile blower usually includes a motor and an impeller arranged on the main shaft of the motor. Due to assembly errors and machining errors, the impeller is prone to vibration when rotating at high speed. Therefore, dynamic balance detection is required after the impeller and the motor are assembled. The existing dynamic balance detection equipment has a complex structure and high cost, and it is difficult to apply to the testing of blowers of different specifications.

[0003] A patent with the publication number CN211553184U discloses a dynamic balance detection platform for automobile blowers, which includes a bottom plate, a column arranged at the left rear side of the bottom plate, a quick clamp arranged at the top of the column and facing forward, a probe fixing frame arranged at the right rear side of the bottom plate, and a laser probe arranged on the probe fixing frame. The detection point of the laser probe is located on one impeller of the automobile blower to be detected. A motor positioning component is arranged on the top of the bottom plate. The motor positioning component includes two support seats arranged parallel to each other left and right on the top of the bottom plate, and a V-shaped block arranged on the top of the support seat, with the opening of the V-shaped block facing upward. In the utility model, the motor is more stably supported by the V-shaped blocks on the two parallel support plates, effectively avoiding the protruding shape of the motor, and having a wider applicability.

[0004] Although the above device has adopted the design of a clamping head and a V-shaped block to fix the automobile blower, during the dynamic balance detection, the rotational movement of the blower inevitably generates vibration. Unfortunately, the current device is insufficient in preventing the displacement caused by this vibration. It mainly relies on the limited friction between the clamping head and the blower to maintain the position stability. This method is ineffective and extremely likely to cause the blower to shift during the detection process, directly affecting the accuracy and reliability of the detection result and reducing the precision of the entire detection process.
