[0002] With the continuous development of the automobile industry, the manufacturing and testing technology of engine cooling fan blades has also been continuously improved. As a key component of the engine cooling system, the accuracy of the size, shape and position of the fan blade is directly related to the cooling effect and service life. Therefore, it is of great significance to accurately measure the fan blade. The fan blade three-coordinate measurement bracket is a measuring fixture designed specifically for fan blades. It is used to accurately measure the size, shape and position of the fan blade on three coordinate axes. Traditional fan blade measurement methods often use manual measurement or simple fixtures for measurement. These methods have low accuracy and efficiency and cannot meet the needs of modern automobile industry for high-precision measurement. Although the existing fan blade measurement bracket has improved the measurement accuracy and efficiency to a certain extent, it still needs to be improved in terms of stability and ease of operation.

[0003] Therefore, this proposal aims to design a new type of fan blade CMM measurement bracket, which can improve measurement accuracy and efficiency, reduce operation difficulty, and meet the needs of the modern automotive industry for high-precision measurement by optimizing the structural design.
