AI Technical Summary

Technical Problem

The existing crankshaft flat square symmetry detection tools are inconvenient to carry, and it is impossible to achieve rapid online inspection during crankshaft processing, and there is a lack of online inspection tools specifically used to detect crankshaft flat square symmetry.

Method used

A crankshaft flat square symmetry rapid inspection tool was designed, using an L-shaped inspection tool holder and a measuring gauge. By fitting one end of the L-shaped inspection tool holder with a flat side and measuring the highest point of the journal at the other end, recording the height difference between the two sides to obtain the symmetry error, and measuring the width of the flat square with a micrometer, calculating the distance dimension of each plane from the axis center.

Benefits of technology

It realizes fast online detection of double-plane and single-plane squares, without placing the crankshaft on the detection platform, and can perform rapid measurements anytime and anywhere, improving the convenience and accuracy of detection.

Abstract

The utility model provides a crankshaft flat-square symmetry rapid detection tool, relates to the technical field of crankshaft detection, and solves the technical problems that an existing flat-square symmetry detection tool is inconvenient to carry and cannot realize flat-square rapid online detection in the crankshaft processing process. The testing fixture comprises an L-shaped testing fixture frame, one end of the L-shaped testing fixture frame is attached to a flat surface, and the other end of the L-shaped testing fixture frame is provided with a measuring meter used for measuring a journal. According to the utility model, rapid online detection of a double-plane flat square and a single-plane flat square can be realized, the crankshaft does not need to be specially placed on a detection platform or a three-coordinate measuring machine for measurement, and the crankshaft flat square can be rapidly measured at any time and any place, which is convenient and rapid.
