Both ends of the second lead screw are respectively mounted on second support blocks on the outer sides of both ends of the transverse base plate, such that the second lead screw engages with threaded holes in the guide slider. A mounting plate is installed outside one of the second support blocks, and a second servo motor is mounted on the mounting plate, such that the drive shaft of the second servo motor is connected to one end of the second lead screw. A second support seat is mounted on the second guide block, and a horizontal plate is mounted above the second support seat. The support plate is mounted on one end of the horizontal plate.

5. The workpiece straightness detection mechanism as described in claim 4, characterized in that: The second support base has a longitudinally penetrating relief groove above it, and a horizontal relief hole is formed between the relief groove and the horizontal plate. A long strip-shaped second cover plate is provided in the relief hole, and the two ends of the second cover plate are respectively connected to the second support block.

6. The workpiece straightness detection mechanism as described in claim 1, characterized in that: The straightness detection placement station includes a first straightness detection placement station. Multiple L-shaped support blocks are arranged at intervals along the longitudinal direction on the work platform. An L-shaped stop block is provided on the outermost support block at one end. The workpiece can be placed on the support block such that the lower surface and one side of the workpiece are respectively in contact with two right-angled surfaces on the support block. One end of the workpiece can abut against and be supported on one side surface of the stop block. The support block and the stop block together form the first straightness detection placement station.

7. The workpiece straightness detection mechanism as described in claim 6, characterized in that: The straightness detection placement station includes a second straightness detection placement station. A vise is set on the work platform. Each of the two clamping blocks of the vise has a workpiece clamping block on its inner side. Each of the two workpiece clamping blocks has a semi-circular clamping opening on its inner side for clamping a circular workpiece. A support seat is set on the work platform at intervals of two workpiece clamping blocks, and the other end of the workpiece can be placed on the support seat. The two pairs of workpiece clamping blocks and the support seat together form the second straightness detection placement station.
