Abstract
The utility model provides a radius measuring tool for an arc-shaped part. The technical scheme of the radius measuring tool is that a depth gauge extends into the lateral side of a V-shaped iron block through a central square groove of a V-shaped standard iron block and is fixedly connected with the bottom of the V-shaped standard iron block through a screw bolt; the alpha angle of the V-shaped iron block is larger than 0 degree and smaller than 180 degrees, accordingly the radius measuring tool for an arc-shaped part is formed. The radius measuring tool for an arc-shaped part has the advantages of being simple in structure, suitable for arc-shaped parts in any sizes, fast in measuring speed, high in accuracy and convenient to operate. Moreover, as the depth gauge is replaced by dial indicators, the radius measuring tool can also be used for measuring surface shapes of arc-shaped parts.
Description
Technical field
The utility model relates to circular arc feature radius survey instrument, the radius measurement of especially incomplete circular arc part.
Background technology
For the radius measurement of any radius arc part, traditional survey instrument and measuring method are difficult to guarantee measuring accuracy, influence part processing or installation accuracy.
Summary of the invention
The purpose of this utility model provides a kind of circular arc feature radius survey instrument, calculates accurate feature radius size by measurement, guarantees part processing or installation accuracy.
The technical solution of the utility model is: a kind of circular arc feature radius survey instrument, pit gauge is stretched into the side of v block piece by V-type standard iron block center square groove, with bolt itself and V-type standard iron certainly are connected and fixed the bottom, the α angle of V-block less than 180 degree, forms circular arc feature radius survey instrument greater than 0 degree.
The beneficial effects of the utility model are: simple in structure, be applicable to the circular arc part of any size, and only need its V-type mouth is close to the circular arc part, can carry out radius measurement, measuring speed is fast, and the precision height is easy to operate.Substitute pit gauge with dial gauge or clock gauge, can also be used for the measurement of circular arc piece surface shape.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a work synoptic diagram of the present utility model.
Embodiment
With reference to Fig. 1 as can be known, a kind of circular arc feature radius survey instrument, pit gauge 1 is stretched into the side of v block piece by V-type standard iron block 2 center square grooves 3, with bolt 4 itself and V-type standard iron block 2 bottoms are connected and fixed, the α angle 5 of V-block is spent less than 180 greater than 0 degree, A/F 6 can be selected different size for use according to measuring needs, forms the serial circular arc parts measurement instrument of different angles different size.
With reference to Fig. 2 as can be known, the v block piece 2 of circular arc feature radius survey instrument is close to circular arc part 7, measures the distance of dome, pass through formula: radius=K * distance again, can draw the radius of circular arc part 7, constant to V base angle point by mobile pit gauge 1
