Description

Technical Field

[0001] This invention belongs to the field of machine tool technology, specifically a gantry high-speed CNC machine tool. Background Technology

[0002] Machine tools, also known as machine tools or industrial machine tools, are core industrial equipment that uses power to precisely process blanks of metal or other hard materials to obtain a predetermined shape, size, and surface quality. They are recognized as machines that make machines. Gantry high-speed CNC machine tools are vertical CNC cutting machine tools with large stroke, high rigidity, high speed, and high precision. The core components are a gantry frame, a high-speed electric spindle, and a high-dynamic feed system. They are mainly used for efficient and precise milling of large-sized parts / molds.

[0003] Existing high-speed gantry CNC machine tools generate a large amount of fine chips during cutting. These chips enter the machine base along with the coolant. While larger chips pass through the coarse filter, a large number of fine chips remain. This causes the filter element to accumulate rapidly during continuous filtration, leading to blockage. Consequently, the coolant inside the machine base cannot be circulated. Currently, workers have to stop the machine to clean the filter element, which reduces its lifespan and increases the workload for workers, failing to meet the required standards.

[0059] In this embodiment, the drive motor 50 is started, which drives the cleaning conveyor belt 43 to work, so that the cleaning conveyor belt 43 drives the scraping structure 44 to move. When the scraping structure 44 moves into the cleaning box 49, so that the scraping structure 44 is not limited, the limit spring 48 drives the scraping block 62 to move downward, so that the impurities on the scraping block 62 are introduced into the cleaning box 49 and enter the collection box 64 through the discharge chute.

[0060] The third cleaning component in this invention also includes a guide block 51 disposed inside the cleaning box 49 and used in conjunction with the discharge trough. One side of the guide block 51 is aligned with the discharge trough, so that after the scraping structure 44 leaves the guide block 51, the scraped impurities are guided into the discharge trough.

[0061] In this embodiment, when the cleaning conveyor belt 43 moves the scraping structure 44 away from the guide block 51, the scraping structure 44 guides the impurities into the discharge trough, and the limit spring 48 moves the scraping block 62 downward to clean the impurities on the scraping block 62.

[0062] The third cleaning component in this invention also includes a blowing structure 52 disposed inside the cleaning box 49 for cleaning the scraping structure 44 and a transmission block 53 connected to the cleaning conveyor belt 43. One end of the transmission block 53 is coaxially mounted with a third bevel gear structure 54 and a fourth bevel gear structure 55 coaxially connected to the third bevel gear structure 54 and controlling the operation of the blowing structure 52. The third bevel gear structure 54 and the fourth bevel gear structure 55 are coaxially connected through a third transmission rod.

[0063] In this embodiment, when the cleaning conveyor belt 43 is working, the transmission block 53 drives the third bevel gear structure 54 to rotate, the third bevel gear structure 54 drives the third transmission rod to rotate, the third transmission rod drives the fourth bevel gear structure 55 to rotate, and the fourth bevel gear structure 55 drives several blowing structures 52 to rotate, so that the blowing structures 52 clean the impurities on the scraping structure 44 and the cleaning conveyor belt 43, and guide the cleaned impurities into the collection box 64.

[0064] In this invention, a protective box 56 is provided on the outside of the cleaning box 49 to protect the third bevel gear structure 54 and the fourth bevel gear structure 55. A second rotating gear 57 coaxially connected to the blower structure 52 is installed in the protective box 56. A second transmission gear 58 meshes between two adjacent second rotating gears 57. The fourth bevel gear structure 55 is coaxially connected to one of the second rotating gears 57. A third connecting rod is provided on the second rotating gear 57, which extends into the cleaning box 49 and is coaxially connected to the blower structure 52.

[0065] In this embodiment, when the fourth bevel gear structure 55 rotates, it drives the second rotating gear 57 to rotate, the second rotating gear 57 drives the second transmission gear 58 to rotate, and the second transmission gear 58 drives the adjacent second rotating gear 57 to rotate, so that the second rotating gear 57 drives the blowing structure 52 to work.

[0066] In this invention, the blowing structure 52 includes a blowing roller 59 rotatably disposed on the inner wall of the cleaning box 49 and a plurality of blowing blades 60 disposed on the blowing roller 59. The blowing roller 59 and the blowing blades 60 work together to clean the scraping structure 44.

[0067] In this embodiment, when the second rotating gear 57 drives the blowing structure 52 to work, the second rotating gear 57 drives the blowing roller 59 to rotate, and the blowing roller 59 drives the blowing blade 60 to rotate, so that the blowing roller 59 and the blowing blade 60 cooperate to blow the airflow toward the scraping structure 44 and the cleaning conveyor belt 43 to clean the scraping structure 44 and the cleaning conveyor belt 43.

[0068] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
