[0032] Specifically, the fixed plate 1 serves as a basic support component of the entire welding clamping tool, and is used to mount and fix other components. The lifting driver 3 is a lifting cylinder, which is responsible for driving the clamping finger unit and the clamped carbon brush to move up and down to reach the welding station or leave the welding station. The spacing adjustment unit 4 is used to adjust the distance between adjacent clamping finger units. The pull wire cylinder 41 serves as the power source of the spacing adjustment unit 4 to realize the adjustment of the spacing. The pull wire cylinder 41 is a prior art, and the spacing adjustment seat 42 is connected with the pull wire cylinder 41, which is used to mount and fix the first clamping finger unit 5 and the second clamping finger unit 6, and moves with the action of the pull wire cylinder. In the initial state, a plurality of first clamping finger units 5 and second clamping finger units 6 are arranged at a predetermined distance and are in an open state, ready to clamp the carbon brush; the lifting driver 3 is in a lowered state, and the first clamping finger unit 5 and the second clamping finger unit 6 act simultaneously to clamp the carbon brush to be processed. The pull wire cylinder 41 acts to adjust the spacing adjustment seat 42, so that the adjacent first clamping finger units 5 and the adjacent second clamping finger units 6 are spaced at the same distance, ensuring that the carbon brushes can be evenly distributed during the welding process, avoiding mutual interference, and improving the welding quality. The lifting driver 3 is started to drive the first clamping finger unit 5, the second clamping finger unit 6 and the clamped carbon brush to rise to the welding station. At the welding station, the carbon brush is welded and processed by the welding equipment. During this process, the clamping finger unit maintains stable clamping of the carbon brush to ensure the welding quality. After the welding is completed, the lifting driver 3 drives the carbon brush to descend and leave the welding station. The welded carbon brush is collected or guided out through the discharge box 2 for subsequent processing. In this application, the spacing adjustment unit 4 can adjust the spacing between the carbon brushes according to the requirements of the welding process, avoid the mutual influence of adjacent carbon brushes during the welding process, and achieve the best welding effect. By adjusting the distance between the adjacent first clamping finger units 5 and the adjacent second clamping finger units 6, the accurate alignment of the carbon brushes on the welding station is ensured, and various specifications of carbon brushes are applicable. By providing a plurality of first clamping finger units 5 and second clamping finger units 6, simultaneous welding of multiple groups of carbon brushes can be realized, and the welding efficiency is improved.
