Online rapid measurement apparatus and method for detecting rivet point dimension

Abstract

The invention relates to an online rapid measurement apparatus and method for detecting rivet point dimension. The measurement apparatus comprises a measurement bottom plate, wherein one end of the measurement bottom plate is provided with a stretching cylinder, the cylinder is connected with a rivet point dimension detection assembly on the measurement bottom plate through a coupling, the surface of the measurement bottom plate at one side of the rivet point dimension detection assembly is provided with a sensor assembly, the sensor assembly directly faces the rivet point dimension detection assembly, and the rivet point dimension detection assembly performs side-to-side movement under the control of the stretching cylinder, and cooperates with the sensor assembly to detect rivet point dimension. The online rapid measurement apparatus and method solve the problems that online rapid measurement for the rivet point dimension cannot be performed in the prior art, an artificial detection period is long, artificial detection efficiency is low, and as there is little difference between rivet point deflections, the possibility of misjudgement is high. The online rapid measurement apparatus can perform accurate online monitoring for the rivet point dimension during mass production and after riveting, and detects whether a rivet point is qualified, accurate and reliable with high efficiency, thereby improving safety performance of the whole product, and ensuring consistency of the produced products.

Description

technical field [0001] The invention relates to a detection device and a detection method, in particular to an online rapid measurement device and a measurement method applied to the size and deformation of riveting points. Background technique [0002] At present, in the field of mass production of industrial machinery manufacturing parts, riveting technology is often used. Through a strong high pressure, cold extrusion plastic deformation occurs between the workpieces, and two layers of different materials and different thicknesses or Multilayer panels are connected. As a result, the effect of locking is produced, because the riveting technology has a firm and reliable connection point, no raw material consumption and no auxiliary materials, beyond the limitations of metal materials and thickness, will not damage the protective layer on the surface of the workpiece, and does not require pre- or post-processing And many other advantages, so riveting technology is widely us...
