Abstract
The invention relates to a concentricity tester measuring head which comprises a measuring head handle, a measuring head extending part, a transition part arranged between the measuring head handle and the measuring head extending part, and a circular arc test head arranged at one end of the measuring head extending part, wherein the circular arc test head at least includes a circular arc spherical part of which the diameter gradually increases and then gradually decreases in the extending direction of the measuring head handle. The concentricity tester measuring head of the invention has the beneficial effect that the concentricity tester measuring head is used for measuring a hole band circular arc surface and is high in measurement precision, easy in operation and low in cost.
Description
Technical field
The present invention relates to a kind of measuring tool, particularly a kind of gauge head for concentricity tester.
Background technology
Concentricity apparatus is the instrument for the concentricity of test piece, to differentiate the qualification of workpiece.Usually, test piece comprises screw screw, rivet, screw rod etc.
In prior art, usually concentricity tester is for comparatively simple, the regular workpiece of test structure, workpiece for structure irregularity, such as, pore area arc surface workpiece, the gauge head of existing concentricity tester is difficult to meet test request, Given this, is necessary very much to provide a kind of measuring head of new concentricity apparatus to meet existing demand.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of and can meet the concentricity apparatus gauge head that pore area arc surface concentricity of workpiece is measured.
For achieving the above object, the present invention is by the following technical solutions:
A kind of concentricity apparatus gauge head, the circular arc measuring head that comprises gauge head handle, gauge head extension, is located at the transition part between described gauge head handle and described gauge head extension and is located at described gauge head extension one end, described circular arc measuring head at least comprises a circular arc spherical surface portion, on the bearing of trend of described gauge head handle, the diameter of described circular arc spherical surface portion presents and first becomes gradually the state diminishing gradually more greatly.
Further, described circular arc measuring head also comprises the top contact portion that is located at described circular arc spherical surface portion one end, and described top contact portion is in the direction away from described gauge head handle, and its diameter diminishes gradually.
Further, the end face of described top contact portion is plane.
Further, the diameter of described gauge head extension is less than the minimum diameter of described circular arc spherical surface portion.
Further, the development length of described gauge head extension is greater than three times of development length of described circular arc spherical surface portion.
Further, the development length of described gauge head extension is greater than five times of development length of described circular arc spherical surface portion.
Further, the diameter of described transition part diminishes gradually in the direction away from described gauge head handle.
Further, the maximum gauge of described transition part equals the diameter of described gauge head handle, and the minimum diameter of described transition part equals the diameter of gauge head extension.
Beneficial effect of the present invention is: concentricity apparatus gauge head of the present invention, for the side amount of pore area arc surface, measuring accuracy is high, and easy and simple to handle, with low cost.
