Problems solved by technology
In this way, even though the detection sleeve can pass through the projection welding bolts, the detection of the welding position of the projection welding bolts has actually lost control, which has played a misleading role in evaluating the quality status of the parts, which is not conducive to analyzing and solving problems
And increase the cost of such gages
[0005] For the projection welding bolts on such parts, it is difficult to truly detect the bolts by using a common detection sleeve on the inspection tool

The invention provides a projection welding bolt detection device and a detection method. The projection welding bolt detection device includes a support base and a detection pin, the detection pin is connected to the support base, and the detection pin can Rotate inside, the end of the detection pin is provided with a groove, the groove is C-shaped. The beneficial effect of the present invention is that the projection welding bolt detection device of the present invention can realize the detection of the position of the projection welding bolts, and avoid the inability to detect due to a slight inclination of the projection welding bolts. Provide the most realistic feedback performance for finding problems. The detection operation is simple, the detection efficiency is high, and the data acquisition is convenient and intuitive. Avoid the waste of replacing detection pins due to undetectable parts.
Description
Technical field [0001] The invention relates to the field of mechanical equipment, in particular to a projection welding bolt detection device and a detection method. Background technique [0002] On some body structure parts, such as the front bulkhead welding assembly and the front bulkhead lower mounting plate welding assembly, some projection welding bolts are often designed to install heat insulation pads, air ducts and other parts. Such as figure 1 . Due to the large size of the through holes on parts such as heat insulation pads and air ducts, the perpendicularity requirements of these welding bolts and the sheet metal surface are usually not very high, and a little skew will not affect the installation parts, and the position tolerance The requirements are usually Φ2.0mm, and the welding gun positioning requirements on the welding tool are also not high. In this way, there will be a situation where the projection welding bolt is not perpendicular to the surface of the p...
