Detailed description of the invention
Measurement measurer of the present utility model, comprises gauge block 1, lower gauge block 2 and is connected the limiting plate 9 of gauge block 1, lower gauge block 2, gauge rod 3 is provided with detection plane B13 and detection plane C14. Lower gauge block 2 is provided with gauge rod 3 and slide bar 5, and gauge rod 3, slide bar 5 are solidly connected with lower gauge block 2. Upper gauge block 1 is provided with measurement plane 12 and gauge rod through hole and the slide bar through hole corresponding with gauge rod 3, slide bar 5 on lower gauge block 2, is provided with lining 6 in slide bar through hole. Gauge rod 3 and slide bar 5 are placed in respectively gauge rod through hole and lining 6, between gauge rod 3 and gauge rod through hole, have the gap of 0.02 millimeter, between slide bar 5 and lining 6, have the gap of 0.01 millimeter. Upper gauge block 1 and lower gauge block 2 are provided with gauge head 11 with inclined-plane and corresponding spring buried via hole, and spring 7 is housed in spring buried via hole, and the two ends of spring 7 touch with the bottom of two spring buried via holes respectively. Upper gauge block 1 is connected by limiting plate 9 with lower gauge block 2, and limiting plate 9 is fixed tightly on lower gauge block 2 by screw 8, and the slidiing pin 10 of upper gauge block 1 is placed in the long kidney-shaped hole 15 of limiting plate 9, and can in long kidney-shaped hole 15, slide up and down.
