Abstract
The utility model relates to an inner arc inspecting template comprising an inspecting template body, wherein at least one corner of the inspecting template body is provided with an arc, a center of the arc is arranged at an inner side of the inspecting template body. The utility model solves the technical problems of complex structure and difficult operation of the existing arc inspecting. The inner arc inspecting template of the utility model has the advantages of simple structure and easy operation.
Description
Technical field
The utility model relates to a kind of interior circular arc and detects model.
Background technology
Casting finished products is when doing size detection, and circular arc in needing to measure still has circular arc inspection apparatus complex structure now and is 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 inner 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 interior circular arc and check model.
Technical solution of the present utility model:
Interior circular arc is checked model, comprises checking the model body, and its special character is: 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 inboard 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 inboard 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, interior circular 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 inboard 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. interior circular 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 inboard of checking the model body.
2. circular arc is checked model in according to claim 1, 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 inboard of checking the model body.
