Center hole radial circle run-out detection tool and batch detection method

Abstract

The invention discloses a center hole radial circle run-out detection tool and a batch detection method. The detection tool comprises a horizontal pedestal, a front support bearing, a rear support bearing, a positioning bearer located above the front side of the horizontal pedestal, a positioning ring installed on the upper portion rear side of the positioning bearer and used for positioning the detection end of a sheared billet to be detected, a dial indicator stand located on the front side of the positioning bearer, and a lever indicator installed on the dial indicator stand. The batch detection method comprises: step 1, detecting center hole radial circle run-out for the first time: sheared billet horizontal placement, dial indicator installation and radial circle run-out detection; step 2, detecting center hole radial circle run-out for another time: sheared billet horizontal placement and radial circle run-out detection; and step 3, repeating step 2 until completing the center hole radial circle run-out detection process for all sheared billets to be detected. The center hole radial circle run-out detection tool and the batch detection method have the characteristics of reasonable design, easy operation, sound use effect, and accurate detection result, and can easily and rapidly detect center hole radial circle run-out.

Description

technical field [0001] The invention belongs to the technical field of circular runout detection, and in particular relates to a center hole radial circular runout detection tool and a batch detection method. Background technique [0002] Circular runout refers to the difference between the maximum and minimum readings measured by a fixed-position indicator in a given direction when the measured element rotates around the reference axis for one revolution. The circular runout tolerance is the maximum allowable variation of the indicator value when the measured element rotates one circle around the datum axis at a fixed reference point (parts and measuring instruments have no axial displacement). Circular runout tolerances can be divided into four categories according to the geometric characteristics and measurement directions of the measured elements: radial circular runout tolerances, end face circular runout tolerances, oblique circular runout tolerances and oblique (angle...

Therefore, the detection data is greatly affected by the radial runout value of the product

[0013] From the above, it can be seen that the figure 1 When the existing detection tool shown in the figure is used to detect the radial runout of the central hole (that is, the detection of the outer circular runout of the central hole), not only the operation is complicated, but the detection efficiency is extremely low, and it cannot meet the requirements of batch detection; and the detection data is also affected by the structure of the tool itself. , the detection data deviates from the actual value, the detection accuracy is low, the detection data accuracy is low, and the measurement result has a large error, which cannot meet the needs of finishing.
