[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 4 The utility model provides a gantry structure for a machine tool base: comprising a base 1, two columns 2 are arranged on the top of the base 1, a plurality of sand discharge vents 3 are arranged on the columns 2, a connecting beam 4 is fixedly arranged between the two columns 2, a chip discharge funnel 5 is arranged on the top of the base 1, and a chip discharge channel 6 is arranged at the bottom of the chip discharge funnel 5;

[0027] Reference Figures 2 to 4In order to reduce the difficulty of cleaning, a cleaning structure 7 is provided on the inner wall of one side of the chip removal channel 6. The cleaning structure 7 includes an outer sleeve 701 movably connected to the inner wall of one side of the chip removal channel 6. A push plate 702 is fixedly provided at one end of the outer sleeve 701. Scrapers 703 are fixedly provided on both sides of the push plate 702. The two scrapers 703 are in contact with the inner wall of the chip removal channel 6. The thickness of the scrapers 703 is two millimeters. The arrangement of the scrapers 703 can scrape off the debris attached to the inner walls on both sides of the chip removal channel 6, which can improve the thoroughness of cleaning. An arc groove 705 is provided on the top inner wall of the outer sleeve 701. A plurality of positioning holes 706 are provided on the inner wall of the arc groove 705. A telescopic rod 708 is movably provided in the outer sleeve 701. A first spring 707 is fixedly provided on the inner wall of the outer sleeve 701. One end of the telescopic rod 708 is fixedly connected to the first spring 707 Then, a limit plate 710 is fixedly arranged at one end of the telescopic rod 708, and a storage hole 711 is provided on the telescopic rod 708. A second spring 712 is fixedly arranged in the storage hole 711, and a push rod 714 is fixedly arranged on the top of the second spring 712. The top of the push rod 714 is arc-shaped, and one arc-shaped end of the push rod 714 is matched with the arc groove 705 and the positioning hole 706. A same guide plate 713 is fixedly arranged between the second spring 712 and the push rod 714, and the guide plate 713 is movably connected to the storage hole 711. Before cleaning, the length of the telescopic rod 708 is first adjusted. After the adjustment, the user pushes and pulls the telescopic rod 708, and the telescopic rod 708 drives the push plate 702 and the scraper 703 to clean the debris in the chip removal channel 6. There is no need for relevant personnel to hold a brush to clean the debris. Quick cleaning can still be achieved in a narrow working environment, reducing the difficulty of cleaning.

[0028] Reference Figure 2 In order to limit the telescopic rod 708, limiting grooves 704 are provided on the inner walls of both sides of the outer sleeve 701, and two limiting bars 709 are fixedly provided on the outside of the telescopic rod 708. The limiting bars 709 are adapted to the limiting grooves 704, and the limiting bars 709 are stuck in the limiting grooves 704, which can effectively prevent the push plate 702 and the scraper 703 from being unable to clean the debris in the chip removal channel 6 due to the rotation of the telescopic rod 708;

[0029] Working principle: when it is necessary to clean the debris or oil and water in the chip removal channel 6, first press the push rod 714 downward, the push rod 714 squeezes the guide plate 713, and the guide plate 713 squeezes the second spring 712. When the arc end of the push rod 714 retracts into the arc groove 705, the telescopic rod 708 is pulled outward. After the push rod 714 moves to the position of the positioning hole 706, the push rod 714 pops out of the positioning hole 706 to adjust the length of the cleaning structure 7. When the telescopic rod 708 is extended to an appropriate length, the user can hold one end of the telescopic rod 708 and push the telescopic rod 708 forward. The telescopic rod 708 drives the outer sleeve 701, and the outer sleeve 701 then It drives the push plate 702, and the push plate 702 in turn drives the two scrapers 703. The bottom of the push plate 702 fits against the bottom of the chip removal channel 6 to discharge the debris out of the chip removal channel 6. The scrapers 703 can scrape off the debris attached to the inner walls on both sides of the chip removal channel 6. There is no need for relevant personnel to clean the chip removal channel 6 with a hand-held brush, which can reduce the difficulty of cleaning the equipment. When not in use, the push rod 714 is pressed down to retract the telescopic rod 708 into the outer sleeve 701, which can reduce the space occupied by the structure. The setting of the two limit plates 710 can limit the telescopic rod 708 to prevent the user from pushing and pulling excessively, causing the cleaning structure 7 to separate from the chip removal channel 6.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
