The utility model discloses a measuring tool is measured to terminal surface annular diameter, simple structure, manufacturing costs hang down, the processing ease, the slide rule removes in a flexible way, has shortened measuring time, has improved measurement of efficiency, promote the slide rule and can adjust slip gauge head position, the gauge head with by measurement station contact stability good, measurement accuracy is high, the good reproducibility, the indicating value precision reaches 0.02 millimeter, the terminal surface annular diameter that can be used to different specifications is measured, the commonality is good.
Description
Technical field
The utility model relates to a kind of measuring appliance, is specifically related to a kind of end face annular groove diameter measurement measurer of axial workpiece.
Background technology
A lot of axial workpieces, have narrow cannelure on end face, the diameter dimension of groove will be measured. General groove width all only has 2-3 millimeter, and slide measure, because gauge head is too wide, is put to be entered, and cannot measure. If design specialized measurer, a measurer can only be measured a size, and cost is too high.
Summary of the invention
The purpose of this utility model is to overcome existing shortcoming in above-mentioned measurement, provides a kind of simple in structure, use easy to operate, the end face annular groove diameter measurement measurer that certainty of measurement is high, measurement category is wide.
End face annular groove diameter measurement measurer of the present utility model, comprises main scale and slide rule, it is characterized in that: the fixing card base of described main scale is provided with fixing gauge head, and the slip card base of slide rule is provided with slip gauge head; Described slide rule is provided with housing screw and vernier, vernier by screws tighten on slide rule.
In order to realize better above-mentioned purpose:
Between described main scale and slide rule, be provided with clamping leaf spring.
Between described main scale and slide rule, there is the gap of 0.005～0.015 millimeter.
Described fixing gauge head and slip gauge head are of similar shape, and are boss type circular arc gauge head.
End face annular groove diameter measurement measurer of the present utility model, simple in structure, manufacturing expense is low, processing ease, slide rule moves flexibly, and Measuring Time is short; Promoting slide rule is adjustable probe location, and gauge head and measured point contact stabilization are good, and certainty of measurement is high, reproducible, and indicating accuracy reaches 0.02 millimeter, can be used for the end face annular groove diameter measurement of different size, and versatility is good.

Detailed description of the invention
End face annular groove diameter measurement measurer of the present utility model, comprises main scale 1 and slide rule 2. The fixing card base 11 of main scale 1 is provided with fixing gauge head 7, and the slip card base 22 of slide rule 2 is provided with slip gauge head 8. On slide rule 2, establish housing screw 4 and vernier 3, vernier 3 use screws 5 are fixed tightly on slide rule 2. Between main scale 1 and slide rule 2, be provided with clamping leaf spring 6. Gap between main scale 1 and slide rule 2 is 0.01 millimeter. Fixing gauge head 7 and slip gauge head 8 are of similar shape, and are boss type circular arc gauge head, and gauge head width is B.
When use, left hand is held part, and the right hand is held measurer, stirs slide rule 2 to the right with right hand thumb, and main scale 1 and the distance of slide rule 2 are transferred to and are applicable to tested annular groove position. To fix gauge head 7 and slip gauge head 8 stretches in tested annular groove, and make the fixing gauge head 7 of main scale 1 be adjacent to part. Right hand thumb toLeftStir slide rule 2, until the slip gauge head 8 of slide rule 2 is also adjacent to part, tighten housing screw 4, the value reading from vernier 3 is exactly the external diameter value of tested part end face annular groove.
On the contrary, if toRightStir slide rule 2, until the slip gauge head 8 of slide rule 2 is also adjacent to part, read numerical value from vernier 3, this numerical value is added to gauge head width value B, acquired results is exactly the inner diameter values of this annular groove.
