[0001] The utility model relates to the technical field of positioning and measuring point fixtures, in particular to a six-point positioning and measuring point fixture. Background Art

[0002] At present, in the processing and manufacturing of aviation medical products, in order to save material and processing costs, blanks are often cast through precision casting. Before fine processing, the blanks need to be precisely calibrated to the datum to achieve the overall precision dimensional requirements of the parts. Since the products to be processed are special-shaped, it is difficult to find the casting base of the products before processing. Traditional clamping uses a horizontal clamping method with few positioning surfaces and unstable positioning. It is difficult to ensure consistency during batch processing. Therefore, it is necessary to design a positioning measuring point fixture that can adjust the height of the workpiece in all directions and use the 6-point positioning method to quickly and accurately find the spatial surface datum of the product.
