A device for preventing overlap welding of nut welding is used in the field of nut welding. The fastening copper plate of the electrode arm on the spot welding machine is connected with the piston rod of the cylinder on the spot welding machine, and the main body is fixed on the spot welding machine; the positioning support and the guiding support of the main body are respectively connected with the connecting plate; the guiding rod passes through the positioning support The seat and the guide support hole are fixed on the positioning support through the manual fixing bolt of the guide rod; the sensor is connected to the sensor fixing support welded at the lower end of the guide rod; the induction end of the sensor and the upper electrode arm are fastened to the bottom surface of the copper plate M The distance L, the distance L1 from the bottom surface of the upper electrode to the surface of the nut is equal to L, the nut is placed on the plate, and the plate is placed on the lower electrode; the cylinder of the spot welding machine runs downward, and the sensor can sense the upper electrode at this time The arm fastens the M surface of the copper plate, and the spot welder can only weld one nut. The invention can prevent lap welding during nut welding, effectively improve production efficiency and quality, and realize the safety of production operations.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a device for preventing lap welding of nut welding. Background technique [0002] With the development of the automobile industry, the nut welding method used in the assembly of vehicle parts has become more standardized, and the equipment for welding nuts has also become more automated. After improving the original welding equipment for manually placing nuts, an automatic nut conveying device is currently used to weld nuts and plates. While the nut automatic conveying device improves the nut welding efficiency during the production operation, it cannot guarantee that only one nut is welded at the same welding position during the welding operation. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a device for preventing lap welding of nut welding, so as to solve the quality problem of...
