Portable curve-controlled high-precision steel rail profile modeling grinding machine

Abstract

The invention discloses a high-precision profile modeling grinding technology. According to the high-precision profile modeling grinding technology, a steel rail section curve is used for carrying out synchronous amplification to form a running track of a control motor and a running track of a grinding wheel, a steel rail face is compared with a weld joint, and therefore the grinding precision of the grinding wheel is precisely controlled, and a steel rail body is not damaged. Especially, two synchronous running tracks, namely, a grinding wheel moving control guide groove and a motor motion fixed tooth channel, are arranged on a saddle-shaped fixed backer, and the grinding wheel of a grinding machine is controlled to carry out grinding only along the tracks. A motor fixed round guide rod penetrates through a motor moving round guide groove to control the motor to vertically move, and the grinding wheel is made to precisely grind the arc face of a steel rail with a fixed distance always. The grinding technology is high in precision, the profile modeling effect is vivid, and the grinding machine can be dismounted to move, and is light and convenient to carry. The phenomena that the grinding precision of other steel rail grinding machines is insufficient, and produced rail faces protrude and are concave are avoided. The problem that the other grinding machines are large in size, heavy and hard to control is solved, and the grinding machine is ideal high-simulation steel rail grinding equipment.

Description

technical field [0001] The invention relates to a high-precision rail weld seam grinding device which utilizes rail section curves to control the grinding track of a grinding wheel without damaging the rail matrix. In particular, it is a kind of rail welding special equipment that synchronously enlarges the section curve of the rail to form a slideway for the motor movement track, and controls the movement of the grinding wheel along the track with a fixed distance to precisely grind the weld seam of the rail. Background technique [0002] At present, when grinding the weld seam produced by rail welding at the construction site, various rail profiling grinders are used, whether it is an electric profiling grinder or an internal combustion profiling grinder, to grind the top arc surface of the rail and When it comes to the curved surface of the edge, the arc trajectory of the grinding wheel of the grinding machine is artificially controlled, and the standard rail arc surface ...

Problems solved by technology

[0004] The present invention adopts synchronous amplification by using the rail surface curve of the rail section, uses the enlarged curve to control the running track of the grinding wheel, and compares the original rail surface with the welded rail seam, so as to accurately control the grinding accuracy of the grinding wheel without damaging the rail The high-precision profiling grinding technology of its own parent body, and it can be assembled, disassembled and moved, light and handy, and easy to carry; the invention solves the phenomenon of rail surface protrusions and depressions caused by insufficient grinding accuracy of other rail grinding machines, The profiling effect is realistic, and the arc surface of the rail is polished accurately. At the same time, it also solves the problems of large size and heavy weight that are difficult to control for other grinding machines, and improves the welding seam grinding accuracy after rail welding on the construction site, thereby ensuring the safety of vehicles.
