Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool chip removal machines, in particular to an automatic chip removal device for a numerically controlled machine tool. Background Art

[0002] The automatic chip removal device of CNC machine tools, also known as the automatic chip conveyor of CNC machine tools, is a key auxiliary equipment in the field of modern mechanical processing. Through a precisely designed chip removal path and a powerful drive system, this device can collect chips and waste generated during the processing in real time, preventing them from accumulating inside the machine tool or in the working area, reducing wear on the tool and workpiece, and extending the service life of the machine tool. At the same time, automatic chip removal also improves the workshop environment, reduces the cleaning burden on workers, and improves the automation level of the entire production line. Its intelligent control system can automatically adjust the chip removal mode according to the processing task, ensuring that the chip removal process is both efficient and reliable, and is an indispensable part of modern intelligent manufacturing. At present, the automatic chip conveyor of CNC machine tools includes a protective conductor connected to the machine tool and a transmission crawler, a transmission wheel set, and a drive motor arranged in the protective conductor housing.

[0003] A Chinese patent with announcement number CN212444306U discloses a chip conveyor for a CNC machine tool, comprising a machine body, a conveyor belt, a bellows and a load-bearing wheel. The inner wall of the machine body is movably connected to the outer wall of the conveyor belt, the bottom of the machine body is fixedly connected to the top of the bellows, the bottom of the machine body is fixedly connected to the top of the load-bearing wheel, the interior of the machine body includes a feed port, a discharge port, a motor, a baffle and a shaft rod, the machine body is S-shaped, a feed port is provided at the top of the machine body, and the bottom of the feed port is fixedly connected to the inner wall of the machine body, a motor is provided at the right end of the machine body away from the feed port, and the bottom of the motor is fixedly connected to the top of the machine body.

[0004] However, the chip conveyor of the CNC machine tool in the above-mentioned prior art is driven by the motor to drive the conveyor belt to rotate, and the conveyor belt transports the chips from left to right. When transported to the air duct below, the fan blows air out from the air nozzle through the air pipe to blow the chips up for air drying. However, in actual use, we found that there are still some shortcomings. For example, when the cutting fluid and metal wire chips enter the feed port, the cutting fluid will seep into the machine body through the conveyor belt. The inability to collect and discharge it will increase the rust damage to the machine body. Secondly, when drying the cutting fluid on the chips, the air duct connected to the pipe is dried by the fan in the bellows, and the drying efficiency is low, and maintenance inside the machine body is also more troublesome.

[0033] Principle and advantages of use: When in use, after the waste chips and cutting fluid of the CNC machine tool enter the feed hopper 3 on the machine body 1, the cutting fluid quickly penetrates through the second through hole 705 through the mesh chain conveyor belt 2 and enters the waste liquid box 701 of the installation frame shell 704 for collection. Through the observation window 703 on the waste liquid box 701, it is convenient to observe the collection of the waste liquid. When draining, the cover of the drainage pipe 702 on the waste liquid box 701 can be removed and connected to the external hose to discharge it into the sewer, which is convenient. In order to centrally collect the waste liquid from cutting and prevent it from remaining in the machine body 1, when the wet waste chips enter the position of the first through hole 403, the electric heating pipe 404 installed in the shell 401 is used to heat the air, and then the fan 402 installed on the shell 401 is used to blow the hot air toward the waste chips on the mesh chain conveyor belt 2, which can improve the air-drying effect of the waste chips. In addition, in this structure, the air-drying elements are centrally installed in the shell 401, and the shell 401 is detachable from the machine body 1, which is also convenient for future maintenance and use.

[0034] When the handle 804 is in the state of being inserted into the waste box 701, the waste box 701 is inserted into the front of the mounting frame shell 704. During the insertion process, the waste box 701 slides and squeezes the inclined surface of the card-in end of the card block 805, so that the rectangular block 807 connected to the card block 805 slides inside the assembly groove 801 and squeezes the spring 802. When the card block 805 corresponds to the position of the card slot 15 on the waste box 701, the spring 802 resets and pushes the rectangular block 807 to slide and make the card-in end of the card block 805 at the lower end be locked and fixed. When the waste box 701 needs to be cleaned, the handle 804 can be pulled upward, so that the handle 804 drives the rectangular block 807 to slide through the connected U-shaped frame 806, and the card block 805 at the lower end of the rectangular block 807 is separated from the card slot 15 at the upper end of the waste box 701, and then the waste box 701 can be pulled out of the mounting frame shell 704.
