Abstract
The utility model relates to an examining sample plate for an outer arc, which comprises an examining sample plate body. At least one corner of the examining sample plate body is provided with an arc, the circle center of each arc is arranged outside the examining sample plate body. The examining sample plate solves a technical problem that the existing examination for the arc is complex in structure and not easy to operate. The examining sample plate has the advantages of being simple in structure and easy to operate.
Description
Technical field
The utility model relates to a kind of external arc and detects model.
Background technology
Casting finished products needs to measure external arc when doing size detection, but has circular arc inspection apparatus complex structure now and be not easy operation.The existing method of measuring circular arc: the reference origin with plane, circular arc place moves on the circular arc theoretical center earlier, make it to become the initial point of newly-built part reference frame, on circular arc, carry out adopting a little of some 2D extreme vectors (a band side radius compensation) then, multiply by 2 after will respectively recording R value calculating mean value after measurement finishes, its result promptly is considered as the circular arc actual diameter, recovers former reference frame subsequently.The process complexity is measured inaccurate.The workpiece finished product is done detection, surveys the workpiece outer arc and is not easy to survey, and surveys by the inspection model.
Summary of the invention
Check complex structure, do not allow easy-operating technical matters in order to solve existing circular arc, the invention provides a kind of external arc and check model.
Technical solution of the present utility model:
External arc is checked model, comprises checking the model body, and its special character is: described inspection model body have one jiao of circular arc that is provided with at least, the center of circle of described circular arc is in the outside of checking the model body.
Four jiaos of above-mentioned inspection model body are provided with the different circular arc of radius, and the center of circle of described circular arc is in the outside of checking the model body.
The advantage that has of the present utility model:
Circular arc of the present utility model is checked model, and is simple in structure, easily operation.When measuring, only need go to check that circular arc is qualified defective with checking that model aligns with workpiece.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cut-open view of the present utility model;
Fig. 3 is a upward view of the present utility model;
Wherein Reference numeral: 1-checks model body, 2-circular arc.
Embodiment
As Figure 1-3, external arc is checked model, comprises checking model body 1, checks that an angle of model body, two angles, three angles or four jiaos are respectively arranged with the different circular arc of radius 2, and the center of circle of circular arc is in the outside of checking the model body.Circular arc of the present utility model is checked model, and is simple in structure, easily operation.When measuring, only need go to check that circular arc is qualified defective with checking that model aligns with workpiece.
Claims (2)
1. external arc is checked model, comprises checking the model body, it is characterized in that: described inspection model body have at least one jiao to be provided with circular arc, the center of circle of described circular arc is in the outside of checking the model body.
2. external arc according to claim 1 is checked model, and it is characterized in that: four jiaos of described inspection model body are provided with the different circular arc of radius, and the center of circle of described circular arc is in the outside of checking the model body.
