Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The jumping detection device of the stepped shaft of the present invention can be applied to various types of stepped shafts of different lengths. For the convenience of description, the present invention will take the left end as a small-diameter section and the right end as a large-diameter section as an example for demonstration.

[0038] As shown in the figure, the present invention includes a horizontal base 1, a left end positioning detection mechanism and a right end positioning detection mechanism;

[0039] The right end positioning detection mechanism includes a right end support frame 22 fixedly connected with the horizontal base 1 to support the right end of the ladd...

Abstract

The invention discloses a stepped shaft run-out detection device which comprises a horizontal base station, a left end positioning detection mechanism and a right end positioning detection mechanism. A stepped shaft form and position tolerance detection device adopts a left and right split positioning mechanism design, the right end is a fixing end, the left end is designed into a two-stage sliding plate structure, and a sliding adjustment manner of a precision slide rail is adopted; after the left part and the right part are adjusted to be coaxial, the form and location tolerance detection demands on stepped shafts with different lengths can be met, so that the multiple purposes of one machine are realized; through the design of the left end positioning mechanism with a pressing mechanism, a workpiece can be ensured not to generate axial rotation in the rotary detection process, so that the measurement accuracy is improved; through an automatic multiple-measuring point measurement design, the display of all sampling points, calculations and results can be completed only by rotating the workpiece for a circle, so that the detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of precision machinery design, in particular to a detection device and a detection method for the runout of a stepped shaft. Background technique [0002] A stepped shaft is a common mechanical part, and its shape and position tolerances such as axial runout (end runout) and radial runout (radial runout) will directly affect the overall performance of mechanical products assembled from it. Under normal circumstances, the reference outer circle of the stepped shaft is supported by a V-shaped bearing pair. By setting a dial gauge (or dial gauge) at each detection point, the workpiece is rotated for one week, and the difference between the maximum value and the minimum value of the displayed value is recorded as Jump detection value. Using this method to detect each parameter needs to move the measuring tool, and each measurement needs to rotate the workpiece for one week, which seriously affects the detection...
