The invention relates to a micro device used for removing the welding beading of fine filaments. The micro device comprises a base (1), a sliding rod (7) assembled on the base, a grinding sliding block (11) assembled on the sliding rod, a numerical control positioning movement mechanism (15) used for driving the grinding sliding block to slide on the sliding rod, two motors (6) assembled at the two ends of the grinding sliding block and used for fixing and driving the fine filaments (13) to rotate, a tensioning mechanism used for tensioning the fine filaments, a grinding wheel (9) being in contact with the fine filaments fixed between the motors and used for grinding the welding beading, an abrasion dust blowing device (4) used for blowing away residual abrasion dust on the surfaces of the fine filaments, a driving and positioning movement mechanism (15) and a control system (20) of the motors used for fixing the fine filaments and the grinding wheel; the rotating shafts of the motors used for fixing the fine filaments are coaxially arranged and rotate in a synchronous manner; the positioning movement mechanism pushes the fine filaments to move to the part below the grinding wheel; the grinding wheel rotates along the surfaces of the fine filaments for grinding; and the fine filaments rotate under the action of the motors during the grinding process. According to the micro device used for removing the welding beading of the fine filaments, the welding beading of the fine filaments is removed by automatic grinding, a smooth transition at the welding joint is realized, and the processing efficiency is improved.
Description
technical field [0001] This invention relates to welding equipment, and more particularly to equipment for removing weld flash (burrs) from joints from fine wires that are welded together. Background technique [0002] A common method for welding fine wires together is resistance butt welding. In this type of operation, the ends of two fine wires are grounded together and heated electrically using contact resistance. As the temperature of each wire end increases to reach the forging temperature, the ends of the fine wires are pressed together to squeeze out the molten metal and oxides, and the ends of the two fine wires are upset together. Because the movement of the two fine wires facing each other may reach more than 2 times the wire diameter, so this forging produces a large amount of slag or welding flash on the inner and outer surfaces of the fine wire junction. Weld flash must be removed in order to keep the fine wire joint in good shape. Contents of the invention ...
