The top of the rail is the upper jaw, and the side wall below the upper jaw is the rail waist. After long-term operation, the rail waist needs to be polished and rust-proofed.

[0003] Due to errors in rail manufacturing, there are deviations in the rail waist profile and thickness. In addition, there is a rail bottom slope due to curve design factors on the rail laying line. Therefore, the electric rail waist grinder cannot closely fit the rail waist profile due to the above reasons. This requires the machine itself to have a certain fine-tuning ability. Based on the above defects and deficiencies, it is necessary to improve the existing technology and design a rail waist grinder motor inclination adjustment mechanism. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a rail waist grinder motor inclination adjustment mechanism, which can achieve a closer fit between the grinding wheel and the rail waist contour by adjusting the motors on both sides and the inclination of the grinding wheel, eliminating the influence of rail manufacturing tolerance and other factors on the grinding effect of the machine itself.
