Embodiment Construction

[0034] 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.

[0035] The positioning device for the jump detection of the stepped shaft of the present invention is applicable 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 for example. .

[0036] As shown in the figure, the present invention includes a horizontal abutment 1, a left end positioning mechanism and a right end positioning mechanism;

[0037] The right end positioning mechanism includes a right end support frame 22 fixedly connected with the horizontal base 1 to support the right end of the ladder shaft, and arranged on t...

Abstract

The invention discloses a locating device used for stepped shaft runout detection. The locating device comprises a horizontal base, a left end locating mechanism and a right end locating mechanism. According to the stepped shaft geometric tolerance detection device, the design of the left and right split locating mechanisms is adopted, the right end is the fixed end and the left end is designed into a two-slide-plate structure, the precise guide rail slide adjusting mode is adopted, the left and right parts are adjusted to be coaxial to meet the requirement of geometric tolerance detection of the stepped shafts of different lengths and thus the multipurpose performance can be realized; and axial runout is ensured not to occur in the rotary detection process of the workpiece through the design of the left end locating mechanism equipped with the compressing mechanism so that the measurement accuracy can be enhanced.

Description

technical field [0001] The invention relates to the technical field of precision machinery design, in particular to a positioning device and a positioning method for detecting 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...
