Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a CNC lathe with a dust collection structure. Background Technology

[0002] When CNC lathes are performing machining operations, the interaction between the cutting tool and the workpiece generates a large amount of cutting chips, dust, and oil mist. These pollutants not only affect the surface quality of the workpiece, but also have a negative impact on the operating environment and the health of the operators. In addition, dust and oil mist in the lathe working environment can easily adhere to the surface of the equipment, leading to a decline in equipment performance and increased maintenance difficulty. Therefore, an effective dust collection device is particularly important in CNC lathes.

[0003] A search revealed application number 202322190094.0, which discloses a CNC lathe with a dust collection structure, relating to the field of CNC lathe technology. This invention includes a lathe base, a protective cover slidably connected to the top of the lathe base, a collection box snapped onto the top of the protective cover, a drive motor mounted on the side of the collection box, and a rotating rod fixedly connected to the output end of the drive motor via a coupling. A magnet is slidably connected to the outer surface of the rotating rod, with a fixing plate and a limiting plate at each end of the magnet. The limiting plate is threadedly connected to the rotating rod, and the end of the rotating rod away from the drive motor is fixedly connected to the collection box via a bearing seat. This invention, through the coordinated use of the drive motor, magnet, rotating rod, and limiting plate, allows the drive motor to rotate the rod, and the limiting and fixing plates to fix the magnet to the rotating rod. When a vacuum cleaner sucks in dust, the magnet can attract the metal in the dust, facilitating recycling and greatly improving recycling efficiency.

[0004] Existing dust collection technologies mainly use fixed dust collection hoods to capture dust and oil mist generated during the cutting process. However, since the cutting position of CNC lathes often changes, fixed dust collection hoods often cannot adapt to the changes in the cutting point, resulting in poor dust collection effect. Dust and oil mist in the cutting area are difficult to remove in a timely and effective manner. In addition, existing dust collection devices usually do not have good oil mist separation and recovery functions. Oil mist and metal chips may pollute the dust collection system and affect its long-term stable operation.

[0005] Therefore, those skilled in the art have provided a CNC lathe with a dust collection structure to solve the problems mentioned in the background art. Utility Model Content

[0031] The separation assembly includes a filter plate 17 and an activated carbon plate 18. Both the filter plate 17 and the activated carbon plate 18 are fixedly installed on the inner wall of the collection box 10.

[0032] The lathe base 1 has a blanking groove 19 on its top. A three-jaw chuck 20 is provided on one side of the inner wall of the lathe housing 2. A tool post 21 is provided on the inner wall of the lathe housing 2. The blanking groove 19 is located on the top of the lathe base 1 and is used to discharge waste or metal chips generated during the machining process, so as to avoid the accumulation of waste in the working area and affect the machining accuracy. The three-jaw chuck 20 is located on the inner wall of the lathe housing 2 to fix the workpiece and ensure the stability of the workpiece during the machining process.

[0033] A controller 22 is fixedly installed on the front of the lathe housing 2. An oil outlet pipe 23 controlled by a solenoid valve is fixedly connected to the bottom of the collection box 10. An observation window 24 is fixedly installed on the front of the collection box 10. A sealing plate 25 is detachably installed on one side of the collection box 10.

The edges are sealed with a silicone sealing strip with an interference fit.

[0034] The working principle of this utility model is as follows: First, when in use, the drive motor 11 can be started to rotate its output end, which in turn drives the threaded rod 12 to rotate, so that the moving block 6, which is threadedly connected to the threaded rod 12, can move along the direction of the guide rod 5, which in turn drives the electric telescopic rod 7 to move. Then, according to the cutting position of the CNC lathe, the electric telescopic rod 7 can be started to drive the connecting plate 8 to rise and fall, so that the dust collection hood 9 adapts to the change of the cutting point and moves with the tool, thereby automatically adjusting the rise and fall and position of the dust collection hood 9 according to different cutting positions to ensure the dust collection effect. Then, the output motor 16 is started, causing its output end to drive the impeller inside the centrifugal fan 15 to rotate. The rotation of the impeller creates a negative pressure zone, thereby generating negative pressure inside the collection box 10. This causes the dust collection hood 9 to suck up fine metal shavings and oil mist generated during cutting, allowing them to enter the connecting pipe 13 and then through the spring hose 14 into the collection box 10. The fine metal shavings are then blocked by the filter plate 17 inside the collection box 10, causing them to accumulate on the filter plate 17. The oil mist then passes through the filter plate 17 and enters the activated carbon plate 18. Through the adsorption of the activated carbon plate 18 and the action of the oil-absorbing non-woven fabric layer, the oil falls to the bottom of the collection box 10. Once a portion has accumulated, the oil can be recovered by simply opening the oil outlet pipe 23. When a large amount of fine metal shavings have accumulated, the sealing plate 25 can be removed to collect the fine metal shavings. The activated carbon plate 18 is designed to be detachable for easy replacement.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
