[0002] Resistance welding tongs are indispensable in body-in-white welding, and the electrode cap is a key component to ensure welding quality. The electrode cap of the welding tongs often produces welding slag during spot welding. This is because during the welding process, the electrode cap will directly contact the surface of the weldment, and the high-temperature melted welding material and the oxides and impurities on the surface of the workpiece are easily attached to the electrode cap to form welding slag. As the number of welding times increases, these welding slags may accumulate, affecting the conductivity of the electrode and the quality of the weld. Therefore, regular grinding, cleaning and replacement of the electrode cap are important steps to ensure welding quality. At present, the existing grinding of electrode caps mainly relies on manual grinding or the use of portable grinding tools, and this manual grinding has low precision, is prone to errors due to human factors, and the labor intensity of workers is high, affecting processing efficiency. Therefore, regularly cleaning the welding slag on the electrode cap of the welding tongs or replacing the electrode cap is a key measure to maintain welding quality. In view of this, a parking and electrode cap grinding detection device for body-in-white resistance welding tongs is urgently needed in the industry. Summary of the invention

By using this grinding and detection technology, the electrode cap can be maintained after each welding task, ensuring that the welding clamp is in the best condition for the next welding, reducing current waste and thus reducing overall energy consumption. Cost reduction: Manual grinding and testing of electrode caps not only requires high labor intensity and low efficiency, but also makes it difficult to ensure the grinding quality. This grinding and testing technology can not only replace manual grinding and testing, but also reduce the risk of work-related injuries, improve the grinding and testing efficiency of electrode caps, and greatly improve production safety and reduce labor costs. Improve efficiency: The device can carry 4 welding tongs by using a welding tongs rotating support frame 1. When the electrode caps of the welding tongs in use have too much welding slag and need to be ground, the welding tongs only need to be parked on the welding tongs suspension shock-absorbing frame 108 (such as Figure 7 A), the first servo motor 104 drives the rotating disc 113 to rotate 90 degrees and arrive at the B position of the electrode cap grinding and detection device of the welding clamp for grinding and detection. At this time, the welding clamp at the left side of the A position rotates 90 degrees and arrives at the A position. The robot can grab it and continue welding, which greatly improves the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
