Description

Technical Field

[0001] This utility model relates to the field of chip removal technology for machine tools used in machining, and in particular to a chip removal device for CNC machine tools. Background Technology

[0002] During CNC machine tool machining operations such as milling, turning, and drilling, a large amount of metal chips are generated. If these chips are not cleaned up in time, they will accumulate in the machining area, affecting the normal cutting of the tool and reducing machining accuracy and surface quality. For example, in the machining of precision parts, even a small amount of chip interference can cause dimensional deviations in the parts, making them defective.

[0003] In the prior art, the chips generated during machining on some CNC machine tools are scattered and need to be collected by workers with brushes after the machine is turned off, which hinders the subsequent recycling and processing work, increases workers' working time and reduces work efficiency; therefore, a chip removal device for machining on CNC machine tools is proposed. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A chip removal device for CNC machine tools includes a conveyor box. Two L-shaped rods are fixedly connected to the bottom of the conveyor box. A collection box is fixedly connected to the outside of the two L-shaped rods. A protective shell is fixedly connected to the outside of the collection box. A rotating assembly providing rotational capability is disposed outside the protective shell. Two sliding grooves are formed on the inner wall of the collection box. The rotating assembly is slidably connected to the inside of the two sliding grooves. Two sliding grooves are formed on the inner wall of the conveyor box. A threaded rod is rotatably connected to the inner wall of the conveyor box. A scraper is threadedly connected to the outside of the threaded rod, and the scraper is slidably connected to the inside of the two sliding grooves.

[0007] In the above technical solution, the chip removal device for this machine tool has a stable structure as the conveyor box is connected to the collection box via an L-shaped rod. The protective shell safeguards the rotating components, which slide smoothly within the first slide groove. Inside the conveyor box, the second threaded rod drives the scraper to slide along the second slide groove, efficiently conveying the chips to the collection box for centralized processing and improved chip removal efficiency.

[0008] As a further description of the above technical solution:

[0009] The rotating assembly includes a motor, a threaded rod, a weight, a rotating wheel, a driven wheel, and a belt. The motor is externally fixedly connected to the outside of the protective shell. The output end of the motor is fixedly connected to the threaded rod. The weight is threadedly connected to the outside of the threaded rod. The weight is slidably connected to the inside of the two sliding grooves. The inner wall of the rotating wheel is fixedly connected to the outside of the threaded rod. The inner wall of the driven wheel is fixedly connected to the outside of the threaded rod. A belt is fitted around the outside of the driven wheel and the rotating wheel.

[0010] In the above technical solution, motor one drives threaded rod one to rotate, causing the weight to slide along the slide groove one, ensuring stable operation of the device. The rotating wheel rotates with threaded rod one, driving the driven wheel via a belt, thus rotating threaded rod two. This transmission design is compact and efficient, stably driving the scraper to clean up shavings, improving the reliability and efficiency of the shavings removal device.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the collection box is fixedly connected to a sealing plate, and two connecting blocks are slidably connected to the rear side of the conveying box.

[0013] The aforementioned technical solution utilizes a sealing plate inside the collection box to prevent shavings from overflowing, maintaining the concentration of shavings within the box and improving collection efficiency. The sliding connecting block at the rear of the conveyor box facilitates flexible connection with other components or position adjustment, enhancing the installation and adaptability of the shavings collection device and making it more convenient to use.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the connecting block has two bolt holes, and bolt sets are inserted and connected to the outer side of the connecting block and the inner wall of the conveying box.

[0016] The above technical solution involves bolt holes in the connecting block, which is then connected to the inner wall of the conveyor box via bolt sets. This allows for flexible adjustment of the connecting block's position, facilitating compatibility and installation of the chip-rolling device with different machine tools. Simultaneously, the bolted connection is robust and reliable, ensuring the relative position of the connecting block and the conveyor box remains fixed, thus guaranteeing the overall stable operation of the device.

[0017] As a further description of the above technical solution:

[0018] The top of the conveyor box is fixedly connected to multiple support rods, and the top of the multiple support rods is fixedly connected to a material transfer plate.

[0019] In the above technical solution, multiple support rods on the top of the conveyor box provide stable support, firmly fixing the conveyor plate. The conveyor plate guides the shavings smoothly into the conveyor box, preventing them from scattering. This design makes the shavings conveying process smoother, improves shavings collection efficiency, and enhances the overall practicality of the device.

[0020] As a further description of the above technical solution:

[0021] The material collection box is detachably connected to a movable plate, and multiple cross bolts are inserted through and connected to the outer side of the movable plate and the inner wall of the material collection box.

[0022] In the above technical solution, the movable plate of the collection box is detachably connected to the inner wall via multiple cross bolts. This facilitates periodic opening of the movable plate for cleaning accumulated debris inside the collection box, maintaining the efficient operation of the device. Furthermore, the cross bolt connection ensures a secure connection, guaranteeing that the movable plate will not loosen during device operation.

[0023] As a further description of the above technical solution:

[0024] The bottom of the conveyor box is fixedly connected to a material transfer box, the inner wall of the material transfer box is fixedly connected to two inclined plates, and the outside of the material transfer box is provided with a grinding component that provides rotational capability.

[0025] The above technical solution features a material transfer box at the bottom of the conveyor to receive the shredded material, and an inclined plate on the inner wall guides the shredded material to slide in a specific direction for easy collection. The external grinding component can further process the shredded material, reducing its volume and facilitating subsequent recycling or cleaning, thereby improving the efficiency of shredded material processing and enhancing the applicability of the device.

[0026] As a further description of the above technical solution:

[0027] The grinding assembly includes a second motor, a first rotating shaft, a first gear, a second rotating shaft, multiple crushing rollers, and a second gear. The second motor is externally fixedly connected to the outside of the feed box. The first rotating shaft is externally fixedly connected to the output end of the second motor. The inner wall of the first gear is fixedly connected to the outside of the first rotating shaft. The outer side of the second rotating shaft is rotatably connected to the inner wall of the feed box.

The inner wall of the second gear is fixedly connected to the outside of the second rotating shaft. The outer sides of the second gear and the outer sides of the first gear are meshed with each other.

[0028] In the above technical solution, motor two drives rotating shaft one, which in turn drives gear one to rotate. Gear two, which meshes with gear one, causes rotating shaft two to rotate, thereby causing multiple crushing rollers on rotating shafts one and two to rotate. The grinding assembly can efficiently crush the shredded material, reduce its volume, facilitate subsequent processing and recycling, and improve the efficiency of shredded material processing and the practicality of the device.

[0029] This utility model has the following beneficial effects:

The bolt holes 17 are opened in the inner wall of the connecting block 16, and the bolt group 18 is used to pass through the inner wall of the connecting block 16 and the conveying box 1.

[0045] Multiple support rods 19 are fixedly connected to the top of the conveyor box 1, serving to support the conveyor plate 20. The conveyor plate 20 is also fixedly connected to the top of the support rods 19, acting as the inlet for the rolled chips to enter the conveyor box 1. A movable plate 21 is detachably connected to the outside of the collection box 3. Multiple cross bolts 22 pass through and connect the movable plate 21 to the inner wall of the collection box 3. A conveyor box 23 is fixedly connected to the bottom of the conveyor box 1, serving as a transition channel for the rolled chips from the conveyor box 1 to the grinding assembly. Two inclined plates 24 are fixedly connected to the inner wall of the conveyor box 23, guiding the flow direction of the rolled chips. The feed box 23 is externally equipped with a grinding assembly that provides rotational capability. This assembly includes a second motor 25, which is the power source for the grinding process. A first rotating shaft 26 transmits power within the assembly. A first gear 27 is fixed to the outside of the first rotating shaft 26 and rotates synchronously with it. A second rotating shaft 28 is rotatably connected to the inner wall of the feed box 23 and receives power from the first rotating shaft 26 through the meshing of a second gear 29 with the first gear 27. Multiple crushing rollers 6 are fixed to the outside of the first and second rotating shafts 26 and 28, and are key components for grinding the shredded material. A second gear 29 is fixed to the outside of the second rotating shaft 28 and meshes with the first gear 27. The external of motor 25 is fixedly connected to the outside of the material box 23. The external of rotating shaft 26 is fixedly connected to the output end of motor 25. The inner wall of gear 27 is fixedly connected to the outside of rotating shaft 26.

The external of gear 29 and the external of gear 27 are meshed with each other.

[0046] Working principle: The device is connected to the CNC machine tool through the connecting block 16 and the bolt group 18. The feed plate 20 is aligned with the position of the chips transmitted from the machine tool. When the chips are transmitted to the inside of the conveyor box 1 through the feed plate 20, the motor 5 is started. Its output end drives the threaded rod 7 to rotate. The rotation of the threaded rod 7 drives the rotating wheel 10 to rotate with the threaded rod 7. The driven wheel 12 is driven to rotate through the belt 13, which in turn causes the threaded rod 11 to rotate.

[0047] When the threaded rod 11 rotates, it drives the scraper 14 to scrape the debris inside the conveyor box 1 into the material box 23. At the same time, when the threaded rod 7 rotates, it drives the weight 8 to slide inside the slide groove 9. Then, the motor 25 is started to drive the rotating shaft 26 to rotate. The rotating shaft 26 drives the gear 27 to rotate. The gear 27 drives the gear 29 to rotate. The gear 29 drives the rotating shaft 28 to rotate.

[0048] When rotating shaft 26 and rotating shaft 28 rotate, they drive crushing roller 6 to rotate relative to each other, grinding the debris for further processing. The ground debris is then transferred to the inside of the collection box 3 by gravity. When the weight 8 slides left and right, it compresses the debris inside the collection box 3 into blocks. Then the machine is turned off, and by turning the cross bolt 22, the movable plate 21 is opened, making it easy to remove the debris blocks for recycling.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
