Abstract
Description
technical field
[0001] The invention relates to track equipment manufacturing technology, in particular to a line drawing and grinding tool clamping device. Background technique
[0002] With the rapid development of the rail equipment manufacturing industry, especially the development of high-speed EMUs, welding technology has been widely applied to the rail equipment manufacturing industry; the aluminum alloy car bodies of EMUs are usually formed by welding, such as side walls, underframes, The roof and the like are formed by welding, so the welding quality directly affects the production cycle and manufacturing cost of the entire car body.
[0003] At present, the car bodies of rail vehicles such as EMUs / subway vehicles are welded by aluminum alloy plates. The aluminum alloy sheet needs to be drawn and polished before welding to remove the oxide skin on its surface; after welding, the weld seam also needs to be polished, so drawing lines and grinding takes up a lot of ma...
