[0002] The geometric accuracy detection device for CNC machining centers in flexible production lines is a comprehensive system that integrates multiple detection technologies and equipment. It can accurately measure and evaluate various geometric accuracy indicators of CNC machining centers, including straightness, flatness, parallelism, perpendicularity, and spindle radial runout. It is an important tool for detecting the geometric accuracy of CNC machining centers in flexible production lines. This device is designed to ensure the machining accuracy and stability of CNC machining centers, thereby improving production efficiency and product quality. However, the existing geometric accuracy detection devices for CNC machining centers in flexible production lines still have some shortcomings:

[0003] The existing flexible production line CNC machining center geometric accuracy detection devices still have some problems with unstable workpiece clamping, which causes the workpiece to move or deform during the detection process, affecting the accuracy and reliability of the detection data results, and making it difficult to ensure the subsequent production and processing quality. If the workpiece is not stably clamped during the detection process, it may be offset due to slight vibrations or external force interference, which will directly lead to a decrease in detection accuracy and an inability to accurately reflect the geometric accuracy of the machine tool.

[0004] Therefore, we proposed a geometric accuracy detection device for CNC machining centers in a flexible production line to solve the problems raised above. Utility Model Content
