Gauge block is equipped with gauge rod and slide bar, and gauge rod and slide bar are solidly connected with lower gauge block；The upper gauge block be equipped with measurement plane and with
The corresponding gauge rod through hole of gauge rod and slide bar and slide bar through hole, gauge rod and slide bar on lower gauge block lead in gauge rod through hole and slide bar respectively
It can be slided up and down in hole；The gauge rod is equipped with detection plane B and detection plane C；Set on the upper gauge block and lower gauge block
Have the gauge head with inclined-plane and corresponding spring buried via hole, spring be housed in spring buried via hole, both ends of the spring respectively with two spring buried via holes
Bottom touch；The upper gauge block is connected with lower gauge block by limiting plate, and limiting plate is connected with lower gauge block by screw, with upper gauge block
It is slidably connected.
In order to which above-mentioned purpose is better achieved：
Bushing is set between the upper gauge block and slide bar, the gap for having 0.01~0.05 millimeter between slide bar and bushing.
The left gradient of the gauge head is 15~40 degree, and the right gradient of gauge head is 10~30 degree.
The height difference of detection plane B and inspection plane C at the top of the gauge rod are to be detected the groove width tolerance of part
。
There is 0.01~0.03 millimeter of gap between the gauge rod and the gauge rod through hole of upper gauge block.
The limiting plate is equipped with long kidney-shaped hole.
The upper gauge block is equipped with and the matched slidiing pin of long kidney-shaped hole on limiting plate.
The measurer of the present invention, simple in structure, easy to manufacture, easy to operate, mobile flexible, time of measuring is short, gauge head and quilt
It is good to survey feature contacts stability, repeatability and uniformity are good, improve part processing detection efficiency, effectively reduce part
Manufacturing expense；For the part to be measured of different size, corresponding gauge head and gauge rod are only needed to change, you can complete the inspection of part groove width
Survey, highly practical, good economy performance.
