Tool for detecting jump of parts of shaft type

Abstract

The invention discloses a tool for detecting the jump of parts of a shaft type, and the tool consists of a pedestal, supporting plates, rollers, a space ring, a central spindle, a locking block, a pull rod, an adjusting bolt, an adjusting nut, a handle, a locking shaft, and a thread pin. The tool is characterized in that the supporting plates are arranged on the top surface of the pedestal through positioning grooves, and are fixed on the pedestal through the locking block, the pull rod and the locking shaft; the roller is fixed on the supporting plate through the central spindle and the space ring. According to the invention, the tool employs two groups of supporting plates, rollers and compression mechanisms or more to detect the jump of the parts of the shaft type, improves the interchangeability during the detection of the parts, reduces the machining of dedicated detection tools, reduces the accumulative errors of part detection, reduces the detection damages of the parts, and improves the detection efficiency and precision.

Description

technical field [0001] The invention relates to the runout detection of shaft parts, especially slender shafts, heavy shafts, shaft parts without central holes and hollow shaft parts. Background technique [0002] The known runout detection tool has a deflection meter or a precision V-shaped block group combined with a percentage dial to detect the runout. The above two methods have their own shortcomings: the deflection device cannot detect parts without a center hole. Hollow shafts need to cooperate with mandrels to detect, which increases the cumulative error of part detection. Heavy shaft parts are easy to damage the center hole when clamping, resulting in part detection data deviation. There is no support in the middle of slender shaft parts, which is caused by gravity. The sagging of the part affects the detection data, and the relative runout of the inner and outer diameters cannot be detected. Precise V-shaped block group: During detection, the detection part needs ...

[0002] The known runout detection tool has a deflection meter or a precision V-shaped block group combined with a percentage dial to detect the runout. The above two methods have their own shortcomings: the deflection device cannot detect parts without a center hole

Hollow shafts need to cooperate with mandrels to detect, which increases the cumulative error of part detection. Heavy shaft parts are easy to damage the center hole when clamping, resulting in part detection data deviation. There is no support in the middle of slender shaft parts, which is caused by gravity. The sagging of the part affects the detection data, and the relative runout of the inner and outer diameters cannot be detected

Precise V-shaped block group: during detection, the detection part needs to be in contact with the V-shaped surface and rotate, which may easily cause damage to the part
