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 device and method for detecting a projection welding bolt. The device for detecting the projection welding bolt comprises a supporting base and a detecting pin, the detecting pin is connected with the supporting base and can rotate in the supporting base, a groove is formed in the end portion of the detecting pin, and the groove is in a C shape. The device and method have the advantages that the device for detecting the projection welding bolt can detect the location degree of the projection welding bolt, and the situation that detection cannot be carried out due to the fact that the projection welding bolt is slightly inclined is avoided. Realest feedback presentation is provided for finding problems. The detecting operation is simple, detecting efficiency is high, and data acquisition is convenient and visual. The waste due to the fact that parts cannot be detected and the detecting pin is replaced is avoided.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to a detection device and a detection method for projection welding bolts. Background technique [0002] On some body structural parts, such as the welding assembly of the front bulkhead and the welding assembly of the lower mounting plate of the front bulkhead, 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 via holes on parts such as heat insulation pads and air ducts, the perpendicularity requirements between 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 requirements for the positioning of the welding torch on the welding tool are also not high. In this way, there will be situations where the projection welding...
