Abstract
The utility model discloses a terminal surface circle convenient measuring apparatu of beating has solved that prior art terminal surface circle beats that the check out test set costs an arm and a leg and to operating personnel's the problem of having relatively high expectations, including base, connecting rod, testing platform and amesdial, the amesdial is located on the base, testing platform passes through the connecting rod and is connected with the base, is equipped with the inspection hole on it, and the gauge head of amesdial passes this inspection hole, testing platform's top surface fixedly connected with fixed block, the utility model discloses simple structure, the cost of manufacture is low, convenient to use.
Description
Technical field
The utility model relates to a kind of checkout equipment, is specifically related to the convenient measuring instrument of Circular Run-out Tolerance.
Background technology
Form and position tolerance comprises form tolerance and position of related features.Any part is all made up of point, line, surface, and these point, line, surface are called key element.After machining, the actual feature of part always has error relative to ideal factor, comprises shape error and site error.The function of this kind of error effect engineering goods, should specify corresponding tolerance during design and be labeled on pattern by specified standard symbol.Wherein, position of related features comprises round run-out tolerance, and it refers to that element to be measured measures the variation relative to datum axis in cross section at certain.Circle run-out tolerance is divided into radial run-out, Circular Run-out Tolerance and oblique circle to beat, and wherein the most frequently used is Circular Run-out Tolerance tolerance.Circular Run-out Tolerance tolerance range is along the region that generatrix direction distance is between two of tolerance value t justifies on the measurement face of cylinder of the coaxial arbitrary radial location of datum axis.When measured piece around datum axis without move axially rotate a circle time, on tested surface, the axial runout amount at arbitrary measurement diameter place all must not be greater than defined value.Current Circular Run-out Tolerance checkout equipment is expensive and higher to the requirement of operating personnel.
Summary of the invention
The technical problems to be solved in the utility model is to provide the convenient measuring instrument of Circular Run-out Tolerance, solves the problem that prior art Circular Run-out Tolerance checkout equipment is expensive and higher to the requirement of operating personnel.
The utility model is achieved through the following technical solutions:
The convenient measuring instrument of Circular Run-out Tolerance, comprise base, connecting link, detection platform and clock gauge, described clock gauge is located on base, described detection platform is connected with base by connecting link, which is provided with detect aperture, the gauge head of clock gauge is through this detect aperture, and the end face of described detection platform is fixedly connected with fixed block.
The further improvement project of the utility model is that described clock gauge is located on pole, and this pole inserts in mobile support saddle, and this mobile support saddle is located on base, is provided with horizontal mobile device between mobile support saddle and base.
The utility model further improvement project is, described detect aperture is slotted hole.
The utility model further improvement project is, described fixed block is provided with V-shaped groove near the side at detection platform center.
The utility model further improvement project is, is provided with three bar connecting links between described detection platform and base.
Compared with prior art, tool has the following advantages the utility model:
The utility model structure is simple, and cost of manufacture is low, is placed in by round piece in detection platform, be close to fixed block, datum axis is simulated by V-shaped groove, regulates pole height, make the measuring head of clock gauge and tested end contact, and keep vertical, pointer is returned to zero, and has certain decrement, slowly and equably turning of work piece one week, and observe the fluctuation of clock gauge pointer, get the difference of full-scale reading and least count, as a performance value of the Circular Run-out Tolerance error at this diameter place.As stated above, at tested end face, (diameter A, B, C, D) is measured at four different-diameter places, gets the maximal value in the jerk value measured and end face different-diameter records, as the performance value of the Circular Run-out Tolerance error of this part, easy to use.
Below in conjunction with drawings and Examples, the utility model is described further.
