Abstract
The utility model provides a semicircle external diameter caliber, including measuring instrument and caliber body, the caliber body is (img file='DDA0000858839630000011. TIF'wi='60'he='39' /) type structure, the measuring instrument lower extreme passes the connecting hole at caliber body top center, the fixed setting at caliber body top, the measuring instrument is including the table body, measuring stick and measuring head, the measuring stick runs through the caliber body, the measuring head is installed to the measuring stick lower extreme, both ends are used for the extension line contained angle of the clamping part of centre gripping semicircle external diameter to be 60 degrees about the caliber body, adopt the semicircle external measuring instrument, can on -the -spot short -term test semicircle external diameter part, satisfy the machining demand, be provided with carbide location strip on the caliber body anchor clamps both ends, long -time use can not reduce the measurement face wearing and tearing of caliber body to detect the error.
Description
Technical field
The utility model relates to survey instrument field, particularly relates to a kind of semi arch external measuring instrument.
Background technology
In field of machining, often need to measure semi arch external diameter, because surveyed circular arc is not full circle, and often need to measure at the scene, therefore the utensil of on-site rapid measurement semi arch external diameter is just quite important.
The measuring method of present stage mainly contains: arc height chord length method, radius gauge detection method, three-dimensional detection method.And each defectiveness of above method: circular arc arc length being less than to 180 °, cannot detect with general measurers such as outside micrometers, arc height chord length method mensuration calculates comparatively complicated loaded down with trivial details, and radius gauge detection method show that data precision is poor, and three-dimensional coordinates measurement method is slowly tediously long.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of semicircle external diameter measurer, comprises measurement instrument and measuring appliance body, and described measuring appliance body is
type structure; Measurement instrument lower end, through the connecting hole at measuring appliance bodies top center, is fixedly installed on measuring appliance bodies top; Described measurement instrument comprises table body, sounding rod and measuring head, and described sounding rod runs through described measuring appliance body, and described sounding rod lower end is provided with measuring head.
Further, described measurement instrument is dial gauge.
Further, described measurement instrument is clock gauge.
Further, two ends, described measuring appliance body left and right are 60 degree for clamping the extended line angle of the clamping part of semicircle external diameter.
Further, two ends, described measuring appliance body left and right are provided with wear-resisting positioning strip for the clamping part clamping semicircle external diameter.
Further, two ends, described measuring appliance body left and right clamping part positioning strip is wimet material.
Adopt semi arch external measuring instrument described in the utility model, can field quick detection semi arch external diameter parts, meet machining demand; Two ends are provided with wimet positioning strip to measuring appliance body fixture, and the measuring surface of measuring appliance body can not be worn and torn by long-time use, reduces metrical error.

Fig. 2 is A-A diagrammatic cross-section;
In figure: 1-shows body; 2-sounding rod; 3-measuring head; 4-measuring appliance body; 5-clamping part;
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make those skilled in the art understand advantage of the present utility model and feature, thus more explicit defining is made to protection domain of the present utility model.
A semicircle external diameter measurer as shown in Figure 1, comprises measurement instrument and measuring appliance body 4, and described measuring appliance body is
type structure; Measurement instrument lower end, through the connecting hole at measuring appliance bodies top center, is fixedly installed on measuring appliance bodies top; Described measurement instrument comprises table body 1, sounding rod 2 and measuring head 3, and described sounding rod 2 runs through described measuring appliance body 4, and described sounding rod lower end is provided with measuring head.
Measurement instrument is dial gauge or clock gauge.
Measuring appliance body about 4 two ends are 60 degree for clamping the extended line angle of the clamping part 5 of semicircle external diameter.
Two ends, measuring appliance body left and right are provided with wear-resisting positioning strip for the clamping part 5 clamping semicircle external diameter.
The positioning strip of two ends, measuring appliance body left and right clamping part 5 is wimet material.
Carrying out in practical operation, first by proof-reading block by detection table pointer zero set, namely initially make zero, the semicircle then measuring appliance being directly stuck in detected product can read half external diameter.
The utility model patent can field quick detection semi arch external diameter parts, meet machining demand; Two ends are provided with wimet positioning strip to measuring appliance body fixture, and the measuring surface of measuring appliance body can not be worn and torn by long-time use, reduces metrical error.During measurement, this measuring appliance being clamped measured semi arch, by regulating clock gauge to carry out reading numerical values, adding detection speed.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
