Both ends of the collection box 1 are provided with a connecting mechanism, and the connecting mechanism is fixedly connected to the spindle. The outer side of the oil pipe 5 is provided with a contraction mechanism. A placement ring 15 is provided on the outside of the bottom end of the collecting barrel 14, and the bottom end of the placement ring 15 is fixedly connected to a bottom plate 16, and the bottom plate 16 is fixedly connected to the column of the gantry machining center, so that the collecting box 1 is fitted together with the bottom end of the spindle through the sealing gasket 2, and at the same time, the inlet of the collecting box 1 is set at the position where the lubricating oil drips on the spindle, so that the lubricating oil drips to the inside of the collecting box 1, and the lubricating oil inside the collecting box 1 can be transported to the inside of the collecting barrel 14 through the oil pump 12, and collected centrally by the collecting barrel 14, thereby realizing the recycling of the lubricating oil, and ensuring that the lubricating oil will not drip onto the surface of the workpiece and cause pollution to the workpiece.

[0028] As a further improvement of the present invention, Figure 1 、 Figure 4 and Figure 6 As shown, the retraction mechanism includes a slider 6 fixedly connected to the oil pipe 5, and the outer side of the slider 6 is slidably connected to a connecting tube 11, and the connecting tube 11 is fixedly connected to the column of the gantry machining center. The top of the connecting tube 11 is fixedly connected to an end cover 8, and the oil pipe 5 passes through the end cover 8. One end of the slider 6 is fixedly connected to a spring 7, and the spring 7 is fixedly connected to the end cover 8. Under the action of the spring 7 and the slider 6, the oil pipe 5 can be automatically retracted to the inner side of the connecting tube 11 to prevent the oil pipe 5 from being exposed too much and entangled with the drill bit, affecting the drill bit's processing of the workpiece.

[0029] As a further improvement of the present invention, Figure 1 、 Figure 4 As shown, the top end of the end cover 8 is fixedly connected to a support plate 9, one end of the support plate 9 is rotatably connected to a guide wheel 10, and the oil pipeline 5 is on one side of the guide wheel 10. The guide wheel 10 can be used to guide and support the oil pipeline 5, thereby reducing the friction between the oil pipeline 5 and the end cover 8.

[0030] As a further improvement of the present invention, Figure 4 As shown, the oil delivery pipe 5 between the slider 6 and the bottom end of the connecting tube 11 has a margin for the normal movement of the main shaft, ensuring that the slider 6 can move upward along the connecting tube 11 normally.

[0031] As a further improvement of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the connecting mechanism includes an inner plate 18 fixedly connected to the collecting box 1, the outer side of the inner plate 18 is slidably connected to a fixed shell 17, and the fixed shell 17 is fixedly connected to the main shaft, the fixed shell 17 is fixedly connected to the main shaft, one end of the inner plate 18 is fixedly connected to a screw 20, and the screw 20 is slidably connected to the fixed shell 17, the outer side of the screw 20 is spirally connected to a limiting disk 19, the inner plate 18 can slide on the inner side of the fixed shell 17, so that the collecting box 1 can be separated from the main shaft, thereby facilitating the removal of the filter frame 4 from the inner side of the collecting box 1 for cleaning.

The filter frame 4 can filter impurities in the dripping lubricating oil to prevent the impurities from being collected together with the lubricating oil.

[0033] Working process: When the utility model is used, the lubricating oil leaking from one side of the main shaft will enter the inner side of the collecting box 1 from the entrance of the collecting box 1, and at the same time, the impurities in the dripping lubricating oil can be filtered through the filter frame 4 to prevent the impurities from being collected together with the lubricating oil. When the lubricating oil inside the collecting box 1 floods the filter frame 4, the staff can input the lubricating oil inside the collecting box 1 into the inner side of the collecting cylinder 14 through the oil pump 12 and the oil pipe 5, and collect it centrally through the collecting barrel 14, thereby realizing the recycling of the lubricating oil and ensuring that the lubricating oil will not drip onto the surface of the workpiece to cause pollution to the workpiece, and the main shaft moves with the collecting box 1. During the movement, the collecting box 1 will also move with the oil pipe 5, and the oil pipe 5 will move together with the slider 6 and the oil pipe 5 between the slider 6 and the bottom of the connecting tube 11 through the slider 6. At the same time, the slider 6 can be reset with the oil pipe 5 under the elastic force of the spring 7. When it is necessary to clean the filter frame 4 inside the collecting box 1, the staff separates the limit plate 19 from the fixed shell 17, and then moves the screw 20 downward with the collecting box 1 through the inner plate 18, so that the collecting box 1 is separated from the bottom end of the main shaft with the sealing gasket 2, and then the filter frame 4 is taken out from the inside of the collecting box 1 for cleaning. After cleaning, the filter frame 4 and the collecting box 1 are reset.
