Lead screw straightness detection device and detection method

The invention provides a lead screw straightness detection device and method, the lead screw straightness detection device is used for detecting the straightness of a long-axis part, and the lead screw straightness detection device comprises a rotation driving assembly which is connected with the long-axis part and is used for driving the long-axis part to rotate; the measuring assembly moves in the axial direction of the long-axis part so as to detect the straightness of the long-axis part; when the rotation driving assembly drives the long-axis part to rotate around the first axis, the measuring assembly synchronously moves in the axial direction of the long-axis part so as to measure the space straightness of the long-axis part. The technical problems that a traditional detection mode is affected by human factors, and the detection precision and efficiency are low are solved. 本发明提供了一种丝杠直线度检测装置及检测方法，丝杠直线度检测装置用于对长轴零件的直线度进行检测，丝杠直线度检测装置包括：旋转驱动组件，旋转驱动组件连接长轴零件，且旋转驱动组件用于带动长轴零件旋转；测量组件，测量组件沿长轴零件的轴向移动以检测长轴零件的直线度；其中，
