The application discloses a screw rod part
assembly section lead error detection structure and a detection method, the detection structure comprises an
assembly plate, a screw rod, a wire rail, an extension structure mounting plate, a connecting plate, a plurality of elastic extension test structures, a
pressure sensor and an
eddy current sensor, the wire rail, the screw rod and the extension structure mounting plate are arranged in parallel on the
assembly plate, the connecting plate is fixedly connected with a screw nut seat and is slidingly arranged on the wire rail, each elastic extension
test structure comprises an extension block and a
metal test piece, the extension block is slidingly arranged on the extension structure mounting plate, the
metal test piece is arranged on the extension block, the
pressure sensor is mounted on the connecting plate, and the
eddy current sensor is mounted on the connecting plate and is arranged opposite to the
metal test piece. The application can realize screw
pitch error detection and lead error calculation of a
machine tool in a part assembly stage, improve subsequent assembly process of the screw rod in the part assembly stage, improve assembly precision and assembly efficiency of the screw rod, and avoid the problem that it is difficult to adjust error out-of-tolerance found after whole
machine assembly.
