Detailed ways

As shown in Figures 1 to 3, the inspection tool used to detect the thickness of the workpiece is at least a gasket or a gasket. In particular, the inspection tool includes a inspection tool seat 1 and a stop unit 2 arranged on the inspection tool seat 1 and Pass-through unit 3. In addition, a plurality of screw holes are arranged on the inspection fixture base 1 .

The stop unit 2 is composed of a stop limit plate 21 and two stop screws 22, the two stop screws are respectively matched with a stop washer 23, and the stop screw 22 passes through the stop limit plate 21 and the stop washer 23 And screwed to the screw hole of the inspection tool seat 1, the nut of the stop screw 22 is in contact with the top surface of the stop limit plate 21, and the stop gasket 23 is located between the stop limit plate 21 and the test tool seat 1, The bottom surface of the stop limit plate 21 is parallel to the top surface of the inspection fixture base 1 .

The through-position unit 3 is composed of a through-position limiting plate 31 and two through-position screws 32, and the two through-position screws are respectively matched with a through-position washer 33, and the through-position screw 32 passes through the through-position limiting plate 31 and the through-position washer 33 And screwed to the screw hole of the inspection tool base 1, the nut of the through position screw 32 is in contact with the top surface of the through limit plate 31, and the through position gasket 33 is located between the through limit plate 31 and the check tool base 1, The bottom surface of the through-limiting plate 31 is parallel to the top surface of the inspection fixture base 1 .

The thickness of the stop washer is smaller than the lower limit precision value of the thickness of the workpiece, and the thickness of the through spacer is greater than the upper limit precision value of the workpiece thickness.

The stop limit plate 21, the pass limit plate 31 and the side of the inspection tool seat 1 facing the operator are parallel, and the stop limit plate 21 is adjacent to the side of the inspection tool seat 1 facing the operator, which is convenient for the operator to operate.
