Description

technical field [0001] The invention belongs to the technical field of weld seam grinding, and in particular relates to a rail weld seam automatic grinding device and a grinding method. Background technique [0002] With the development and progress of science and technology, people's requirements for things have changed from the old thinking that can be used to become quite delicate and demanding. Only the idea of ​​continuous improvement or innovation will produce new forms to increase the added value of products. , in order to survive under the test of fierce market competition. In the construction of China's high-speed rail, track manufacturing is an important link, but because most of the manufacturing processes of heavy infrastructure products still retain traditional manual operations, especially the grinding process is the most difficult to be replaced by automation in all production links.

Problems solved by technology

In the construction of China's high-speed rail, track manufacturing is an important link, but because most of the manufacturing processes of heavy infrastructure products still retain traditional manual operations, especially the grinding process is the most difficult to be replaced by automation in all production links. The harsh environment, high labor intensity, and unstable working conditions of the products make this type of work maintain a high-intensity labor operation. With the difficulty of employing labor and the frequent occurrence of work-related injuries, enterprises are becoming more and more overwhelmed

[0003] For rail grinding, the current mature technology is locomotive track grinding and repair technology, that is, on the formed track, the locomotive is used to move, and some grinding equipment is placed between the locomotive and the track to complete alignment during locomotive movement. Grinding of formed rails, but most of the welded blank products before the rails are formed are still in the status quo of manual grinding, and some companies use special machines to grind the upper and lower planes of the rails after welding, and the neck of the rails is done manually
