Guide rail device of high-precision numerical control lathe

The guide rail device comprises a bottom plate, fixing plates are arranged on the two sides of the upper portion of the bottom plate, guide rails are installed on the inner side walls of the fixing plates, a machining table is arranged on the tops of the guide rails, and fixing pieces are connected to the two sides of the bottom of the machining table. And connecting rods are connected to the inner sides of the bottoms of the fixing pieces, rolling wheels are installed at the ends, away from the fixing pieces, of the connecting rods, and the rolling wheels extend into the guide rails to be slidably connected with the guide rails. According to the guide rail device of the high-precision numerical control lathe, the machining table is prevented from impacting the fixing plates at the two ends in the moving process through the arrangement of the protective pads, the stability of the machining table is improved, the limiting grooves correspond to the interiors of the protruding blocks, installation can be conveni
