Measurement of Automobile Fasteners
Accurately measure the screw size based on the established datum line
Automatically measure the physical dimensions concentricity of various screws in ten seconds. The efficiency is much higher than that of traditional measuring tools and methods. (Auto-type: TIMI 12A / 30P)
Background of the Application
According to the requirements of PPAP, the inspection standards for auto fasteners are strict more and more than before. The main measurement items for auto parts are the first thread, mechanical thread, head size and fillet R. In order to measure all dimensions, there are at least three kinds of traditional measuring tools are required.
With a pre-programmed script, TIMI-series measuring machine can continuously measure the first thread, mechanical thread, head size, fillet R ,and other physical dimensions.
Automatically measure more than 15 physical dimensions of a 30mm-long screw in 15 seconds.
Automatically measure the outer diameter, inner diameter, pitch diameter, pitch, thread angle and helix angle of the mechanical thread in one second.
Automatically search for the bud/full thread tips, and measure the effective length of thread.
Automatically measure fillet R whose minimum measurable value is 0.2mm.
Automatically measure the physical dimensions of screw heads of various fasteners.
Automatically measure concentricity of thread and screw head.
Traditionally operators use more than three kinds of measuring tools to measure an automobile screw for several minutes. Now, a full-dimension measurement can be automatically completed in ten seconds by TIMI-series measuring machine. The applications of in-process autonomous inspection improves not only the inspection efficiency but also the yield rate.
