[0060] In this way, when the length of the workpiece is detected, the workpiece to be detected is placed on the workpiece placing station on the workpiece mounting seat, the cross slide drives the left detection rod or the right detection rod on the mounting seat to move, so that the end of the left detection rod or the right detection rod abuts against the end face of the workpiece, and the length of the workpiece is measured by the corresponding grating length gauge. The overall structure is more simple and reasonable, the detection operation is more convenient, and the length detection precision is higher.

A first placing groove 37, a second placing groove 38 and a third placing groove 39 are arranged on the upper surface of the workpiece mounting seat. Three transversely arranged accommodating grooves are arranged on the upper surface of the workpiece mounting seat in a spaced manner. A first stop block 40 is arranged on the bottom surface of one of the accommodating grooves and corresponds to the third placing groove in the middle.

[0080] Specifically, the second support seat is provided with a longitudinal through-positioning slot, and a horizontal through-positioning hole is formed between the through-positioning slot and the horizontal plate. A long strip-shaped second cover plate 67 is arranged in the through-positioning hole, and the two ends of the second cover plate are respectively connected to the second support blocks.

[0082] Specifically, the straightness detection placement station includes a first straightness detection placement station. A plurality of L-shaped support blocks 68 are arranged on the workbench in a spaced manner along the longitudinal direction. An L-shaped stop block 69 is arranged outside the outermost support block at one end. The workpiece can be placed above the support blocks, and the lower surface and one side surface of the workpiece are arranged at right angles to the two surfaces on the support blocks, respectively. One end of the workpiece can abut against the side surface of the stop block. The support blocks and the stop block jointly form the first straightness detection placement station.
[0083] Thus, the first straightness detection placement station is designed more simply and reasonably, and the rectangular structure workpiece can be positioned and arranged more conveniently and more conveniently operated.
[0084] Specifically, the straightness detection placement station includes a second straightness detection placement station. A vice 70 is arranged on the workbench.
