[0025] See also Figure 2 , Figure 3 and Figure 4 The utility model provides a lubrication mechanism dedicated to CNC machine tools. The surplus display structure 5 includes a mounting block 51, which is fixed to the box cover 2 by bolts, and a display plate 52 that runs through the middle of the mounting block 51. The display plate 52 is vertically connected to the mounting block 51 and is slidably connected. An oil baffle block 511 is installed at the bottom of the mounting block 51. The display plate 52 runs through the oil baffle block 511 and is vertically connected to the inner wall of the oil baffle block 511 and is slidably connected to the inner wall of the oil baffle block 511 to prevent the display plate 52 from carrying lubricating oil when sliding upward. To prevent the lubricating oil from slipping out, a residual scale 521 is integrally formed on the front side of the display board 52 so that the staff can check the residual amount. A circular arc-shaped float 53 is fixed to the bottom of the display board 52 by bolts, and the outer surface of the float 53 is smooth to prevent the lubricating oil from flooding the float 53. An air bag 531 is arranged at the upper end of the float 53 to help improve the buoyancy of the float 53. A counterweight 532 is installed at the lower end of the float 53 to help the float 53 always stay on the surface of the lubricating oil.

[0026] Guide wheel grooves 522 are provided on the left and right sides of the display board 52. Guide wheels 523 are located inside the guide wheel grooves 522.

Under continuous filling, the float 53 will push the display board 52 upward to slide along the inner wall of the mounting block 51. When the lubricating oil is filled, the display board 52 will extend out of the box cover 2. The staff can determine the remaining lubricating oil in the box body 1 by checking the height of the display board 52. When the lubricating oil is continuously consumed, the float 53 is always on the surface of the lubricating oil, and the display board 52 will slide downward along the inner wall of the mounting block 51. The remaining lubricating oil in the box body 1 can be determined by observing the height of the display board 52, so that the staff can observe the remaining amount inside the box body 1 without difficulty in checking the remaining lubricating oil due to yellowing dust.
