Rail weld joint grinding robot capable of achieving flexible grinding

Abstract

The invention relates to a rail weld joint grinding robot capable of achieving flexible grinding. The robot comprises an industrial robot and a flexible grinding device. The flexible grinding device comprises a connector, a driving motor, a movable support and an abrasive belt wheel assembly. The output end of the driving motor penetrates through the movable support and then is provided with a driving wheel; the abrasive belt wheel assembly is driven to operate; the abrasive belt wheel assembly comprises an abrasive belt arm and a floating arm. A main wheel, a fixed wheel, a tensioning mechanism and an abrasive belt are included, a rotating column is arranged at one end of the abrasive belt arm corresponding to the floating arm; a swing block is arranged between the abrasive belt arm and the floating arm; the floating arm rotates along the rotating column through the swing block; a tension spring is arranged at the other end of the floating arm corresponding to the rotating column; oneend of the tension spring is connected with the floating arm, the other end of the tension spring is connected with the abrasive belt arm, and the floating arm achieves swing return through the tension spring. The industrial robot clamps the flexible grinding device to grind the rail, the grinding efficiency is improved, excessive grinding is avoided, the movable support can swing leftwards and rightwards, and flexible grinding is achieved.

Description

Technical field [0001] The invention relates to an intelligent processing field, in particular to a flexible grinding orbital weld grinding robot. Background technique [0002] Rails, also called rails, guide rails, and rails, are mainly used for rail transit, while rail transit refers to operating vehicles that need to be track A type of vehicle or transportation system traveling on. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, rail transit has shown more and more types, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. Made of steel, in order to ensure the safety of operating vehicles traveling above, the 100-meter track produced will be welded into a 500-meter long track during the processing process and then transported to the line for laying, and the interface between the tracks will be ...

AI Technical Summary

Problems solved by technology

[0003] The existing grinding process of the track mainly uses CNC to grind the weld seam, but the CNC grinding can only set the height of the weld seam on the track, and then grind the track weld seam under the same specification, while the weld formed during track welding The height of the weld seam is different. When CNC is grinding the weld seam on the track, due to the weld seam of different heights, the welding seam that is too high will not be polished thoroughly, and the welding seam that is too low will damage the track. ontology
