Abstract

The invention relates to an end face ring slot diameter measuring tool, comprising a main scale and a sliding scale, and characterized in that the fixed clamping pin of the main scale and the sliding clamping pin of the sliding scale are respectively provided with boss-shaped arc measuring heads; the sliding scale is provided with a compression screw and a vernier, wherein the vernier is fixed on the sliding scale through the compression screw; a compaction leaf spring is arranged between the main scale and the sliding scale; a gap of 0.005-0.015 millimeters exists between the main scale and the sliding scale. The end face groove diameter measuring tool has the characteristics of simple structure, low manufacturing cost, easy operation and flexible sliding scale movement, shortens measuring time and improves measuring efficiency; the position of a sliding measuring head can be adjusted by pushing the sliding scale; contact reliability between a measuring head and a point to be measured is high, measuring precision and repeatability are great, and indicating value precision can reach 0.02 millimeter; the end face groove diameter measuring tool can be used for diameter measurement of end face ring slots of different specifications, and has great versatility.

Description

End face annular groove diameter measurement measurer
Technical field
The present invention relates to a kind of measuring appliance, be specifically related to a kind of end face annular groove diameter measurement measurer of axial workpiece.
Background technology
A lot of axial workpiece, end face has narrow ring groove, and the diameter dimension of groove will be measured.General groove width all only has 2-3 millimeter, and vernier caliper, because gauge head is too wide, is put to enter, cannot be measured.If design specialized measurer, a measurer can only measure a size, and cost is too high.
Summary of the invention
To the object of the invention is to overcome in above-mentioned measurement existing shortcoming, provide a kind of structure simple, use easy to operate, measuring accuracy is high, end face annular groove diameter measurement measurer that measurement range is wide.
End face annular groove diameter measurement measurer of the present invention, comprise main scale and slide rule, it is characterized in that: the fixing card base of described main scale is provided with fixing gauge head, 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 above-mentioned purpose better:
Clamping leaf spring is provided with between described main scale and slide rule.
The gap of 0.005 ~ 0.015 millimeter is had between described main scale and slide rule.
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 invention, structure is simple, manufacturing expense is low, processing ease, and slide rule moves flexibly, and Measuring Time is short; Promote slide rule and adjustable probe location, gauge head and measured point contact stabilization good, measuring accuracy is high, reproducible, and indicating accuracy reaches 0.02 millimeter, and can be used for the end face annular groove diameter measurement of different size, versatility is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to schematic diagram.
In figure: 1, main scale, 2, slide rule, 3, vernier, 4, housing screw, 5, screw, 6, clamping leaf spring, 7, fixing gauge head, 8, slip gauge head, 11, fixing card base, 22, slip card base.
Embodiment
End face annular groove diameter measurement measurer of the present invention, 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.Slide rule 2 is established housing screw 4 and vernier 3, vernier 3 screw 5 is fixed tightly on slide rule 2.Clamping leaf spring 6 is provided with between main scale 1 and slide rule 2.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 be boss type circular arc gauge head, gauge head width is B.
During use, left hand holds part, and the right hand holds 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 applicable tested ring groove position.Fixing gauge head 7 and slip gauge head 8 are stretched in tested annular groove, makes the fixing gauge head 7 of main scale 1 be adjacent to part.Right hand thumb to leftstirring slide rule 2, until the slip gauge head 8 of slide rule 2 is also adjacent to part, tighten housing screw 4, is exactly the external diameter value of tested part end face annular groove from the value of vernier 3 reading.
On the contrary, if to rightstir 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 gauge head width value B, acquired results is exactly the inner diameter values of this annular groove.
