[0002] Water pump castings are an important part of water pumps. Water pump castings are parts for water pumps made through a casting process. Their manufacturing process and material selection have a direct impact on the performance of the water pump.
[0003] At present, the main function of water pump casting inspection fixtures is to ensure that water pump castings meet design requirements and ensure their normal operation during subsequent assembly and use. Through precise measurement and inspection, dimensional deviations, shape errors, surface defects and internal potential problems in castings can be discovered, which plays a vital role in improving the overall quality, reliability and performance of water pumps.
[0004] However, existing water pumps have different shapes, and using a unified measurement method will not be able to accurately measure the corresponding data, especially since there are shaft holes inside the water pump. In this case, it is difficult to measure the required data, and it is impossible to compare the measured data, which ultimately leads to inaccurate data and affects the final performance of the water pump. A high-precision water pump casting inspection fixture is now proposed to improve the existing problems. Utility Model Content
