Abstract
The utility model discloses a concentricity detecting device, comprising a bottom plate, a bottom roller, a side roller and a dial indicator, wherein the side roller is fixed on one side of the bottom plate through a supporting plate, the dial indicator is fixed on the other side of the bottom plate through a bracket, a measuring rod of the dial indicator and the axis of the side roller are perpendicular to each other and are in the same horizontal plane, the bottom roller is fixed on the bottom plate through an adjustable bracket, and is arranged between the side roller and the dial indicator. The essence of the concentricity detecting device is to measure the changes of wall thickness difference of the products, and the measurement is rapid and accurate, thereby bringing convenience for controlling the product quality to meet the drawing requirements and to ensure the product quality.
Description
Technical field
The utility model relates to a kind of survey instrument, specifically a kind of concentricity testing device of part.
Background technology
No matter be in machining; or in the injection mo(u)lding of plastics; often can run into the requirement that concentricity is arranged between product inner circle and the cylindrical or between them; known concentricity testing device is to adopt three-dimensional to detect; get a little at external cylindrical surface and inner cylinder face respectively; in software, directly measure the concentricity on two faces of cylinder; but the face of cylinder of software building is not the real face of cylinder; but the best-fit face of cylinder; therefore measurement can be subject to the impact of product cylindricity and the impact of tapering, misjudgement may occur.
The utility model content
The purpose of this utility model provides a kind of concentricity testing device, overcomes the deficiencies in the prior art, and it is simple in structure, and it is accurately convenient to measure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Concentricity testing device, comprise base plate, end roller, side wheel and dial gauge, side wheel is fixed on base plate one side by back up pad, dial gauge is fixed on the base plate opposite side by support, the sounding rod of dial gauge is vertical with the axis of side wheel, and be located in the same horizontal plane, end roller is fixed on the base plate by adjustable support, and is positioned in the middle of side wheel and the dial gauge.
The beneficial effects of the utility model are:
The utility model its essence is the variation of the Wall-Thickness Difference of measurement products, and measurement is quick, accurate, and the quality that helps to control product reaches drawing requirement, guarantees product quality.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is measuring principle synoptic diagram of the present utility model.
Embodiment
Shown in Fig. 1 to 2, concentricity testing device, comprise base plate 2, end roller 3, side wheel 4 and dial gauge 1, side wheel 4 is fixed on base plate 2 one sides by back up pad, dial gauge 1 is fixed on base plate 2 opposite sides by support 5, the axis of the sounding rod of dial gauge 1 and side wheel 4 is vertical and be located in the same horizontal plane, and end roller 3 is fixed on the base plate 2 by adjustable support 7, and is positioned in the middle of side wheel 4 and the dial gauge 1.
During use part 6 to be checked is placed between end roller 3 and the side wheel 4, and adjust the position of end rollers 3 by adjustable support 7, be located at part 6 to be checked under, and guarantee that the center of part 6 to be checked and side wheel 4 are in the same level face, the sounding rod of dial gauge 1 is placed inner bore of part to be checked, and make measuring head compress the inner hole wall of part to be checked, one week of rotating part, the difference of the minimum and maximum reading of dial gauge is concentricity difference, in order to reduce error, need to detect in different cross sections, get maximal value as Concentricity tolerance.
More than disclosed be the specific embodiment of this patent only, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, the distortion of making should be considered as belonging to the utility model protection domain.
