Problems solved by technology
Since it is impossible to complete the calibration at one time, it has to be calibrated and tested repeatedly. When the distortion value has an error, the calibration cannot be performed because the measured distortion value has been inaccurate.

Embodiment
[0013] Embodiment: A device for detecting distortion of shaft parts, including the first and second cones 1 and 2, the first and second positioning frames 3 and 4, and the base plate 5, and the first and second cones 1 and 2 are axially stopped respectively. The first and second positioning frames 3 and 4 can be moved and rotated in the circumferential direction, and the first and second cones are distributed in a coaxial state with their tips facing each other. The first and second positioning frames 3 and 4 are radially stopped and the axis It can be stopped and positioned on the base plate 5. At least one of the first and second cones 1 and 2 has elasticity in the axial direction. When testing, the central holes at both ends of the shaft parts are respectively supported on the tips of the two cones. The first and second cones 1 and 2 are clamped by an elastic deformation with axial elasticity in the first and second cones 1 and 2, and the first and second cones 1 and 2 rotat...

The invention discloses a shaft part distortion detection device which comprises a first cone body, a second cone body, a first location frame, a second location frame and a substrate. The first cone body and the second cone body are respectively and axially locked and can be located on the first location frame and the second location frame along the circumferential direction in a rotating mode. The first cone body and the second cone body are coaxially distributed in a tip-opposite mode. The first location frame and the second location frame are locked along the radial direction and can be located on the substrate along the axial direction in a locking mode. A spring is arranged on at least one axial direction of the first cone body and the second cone body. The shaft part distortion detection device brings convenience to assembling and disassembling of refined small shaft parts during measurement. The measured parts can be firmly fixed between the two cone bodies under the effect of the spring. When the measured parts rotate, deviation degree along the axial direction and the radial direction is the smallest, and therefore detection accuracy of distortion is improved. As accurate measurement values are convenient to obtain, convenience is brought to follow-up correction, and production efficiency is improved.
Description
technical field [0001] The invention relates to a detection device, in particular to a detection device for the distortion of shaft parts. Background technique [0002] For fine and small shafts and slender parts, different degrees of distortion (such as bending) will be produced during quenching treatment. When testing, the traditional method is to place shafts on ordinary V-shaped blocks and rotate them manually. Axis, manually corrected according to the distortion value and orientation displayed by the dial indicator. Since it is impossible to complete the calibration once, it has to be calibrated and tested repeatedly. When an error occurs in the distortion value, the calibration cannot be performed because the measured distortion value is already inaccurate. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a distortion detecting device for shaft parts, which has a simple structure, small error in detect...
