Description

Technical Field

[0001] This utility model relates to the field of milling machine equipment technology, and more specifically, to a waste chip cleaning device for milling machines. Background Technology

[0002] Milling machines cut workpieces using rotating cutters, generating a large amount of metal chips during the process. If these chips accumulate in the machining area, they can affect machining accuracy and even damage the cutting tools or workpieces, making timely cleaning crucial. In existing technology, traditional milling machines typically use air guns to disperse the chips at the milling location. If the milling machine is equipped with a cooling system, high-pressure coolant can be used to flush the chips to the bottom of the machine. After milling stops, large areas of chips are initially removed using brushes or air guns. However, this manual cleaning method is insufficient for quickly removing chips from within the milling machine.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] Example 1

[0044] This utility model provides a chip cleaning device for milling machines, including a chip collection plate 1. The chip collection plate 1 is placed manually or installed at the bottom of the working space of the milling machine. A work platform is installed in the working space of the milling machine. When the milling machine mills the workpiece on the work platform, the milled chips are flushed away from the work platform by coolant or airflow and fall onto the surface of the chip collection plate 1 in the bottom space of the milling machine. The flat surface of the plate facilitates subsequent cleaning.

[0045] Furthermore, in order to collect the waste chips on the chip collection plate 1, a suction head 4 is provided on the chip collection plate 1 in this embodiment. The suction end of the suction head 4 is engaged with the chip sweeping assembly 9, and the pump suction end is connected to the pump suction assembly 7 and the cleaning box 5. The chip sweeping assembly 9 sweeps the waste chips on the chip collection plate 1 into the suction end of the suction head 4, whereby they are pumped into the cleaning box 5 for centralized collection and cleaning.

[0046] Please refer to the following: Figure 2 and Figure 3 The suction head 4 includes a suction nozzle 401, a push plate 402, and a telescopic tube 403.

[0047] Specifically, the suction nozzle 401 is snapped onto the chip-sweeping end of the chip-sweeping assembly 9, covering the entire chip-sweeping end. The opening of the suction nozzle 401 faces the surface of the chip-collecting plate 1, ensuring that the waste chips swept up by the chip-sweeping end are completely sucked into the collection box by the suction nozzle 401, preventing them from spreading throughout the milling machine space. A push plate 402 is also fixedly installed at the lower part of the suction nozzle 401. The bottom of the push plate 402 abuts against the surface of the chip-collecting plate 1, and the surface of the push plate 402 is inclined relative to the surface of the chip-collecting plate 1, facilitating the introduction of the swept waste chips into the suction nozzle 401 by the inclined surface of the push plate 402. The suction nozzle 401 is connected to one end of the telescopic tube 403, and the other end of the telescopic tube 403 is connected to the upper part of the cleaning box 5. The pump suction assembly 7 is also installed on the upper part of the cleaning box 5, so that when the pump suction assembly 7 is working, the swept waste chips will be sucked into the telescopic tube 403 and enter the cleaning box 5 due to the pump suction.

[0048] It is worth noting that after the milling machine finishes milling the workpiece, some unremoved chips will still remain on the work platform, which is quite troublesome to clean manually. At this time, the operator can quickly remove the suction nozzle 401 that is attached to the chip removal assembly 9. The suction nozzle 401 is equipped with a handle on the upper part, so the operator can hold the suction nozzle 401 and place it on the processing platform to pump and collect the chips on the surface of the work platform. The telescopic tube 403 can be extended or shortened accordingly (the pipe structure is corrugated to reduce the folding volume) to adapt to the constantly changing chip suction position when the operator holds the suction nozzle 401.

[0049] Furthermore, because the milling machine uses liquid or gas to flush away the chips at the machining location during milling, the collected chips may contain liquid. Moreover, the types of workpieces to be processed are quite diverse, and after a long period of processing, various types of chips will become mixed together, making them difficult to recycle and reuse. Therefore, in this embodiment, the cleaning box 5 is also equipped with a solid-liquid separation structure 8 and a magnetic chip collection assembly 6. The solid-liquid separation structure 8 is used to separate solid chips and rinsing liquid; the magnetic chip collection assembly 6 is used to separate metal chips and non-metal chips.

[0050] For specific details, please refer to Figure 4 and Figure 5 The magnetic chip collection assembly 6 includes a permanent magnet cylinder 601, a motor 602, and a gear 603.

[0051] Multiple permanent magnet cylinders 601 are rotatably positioned in the center of the cleaning box 5 and are evenly distributed in the middle layer of the cleaning box 5. There are gaps between adjacent permanent magnet cylinders 601 to facilitate the passage of waste and liquid. When waste enters the upper part of the cleaning box 5 through the telescopic tube 403, the falling waste will pass through the permanent magnet cylinders 601, causing the magnetic metal waste to be attracted and separated from the non-metallic waste.

[0052] In addition, in order to drive the rotation of multiple permanent magnet cylinders 601, one end of the rotating end of one of the permanent magnet cylinders 601 is fixedly connected to the main shaft of motor 602. Motor 602 is fixed on the cleaning box 5 and drives the permanent magnet cylinder 601 to rotate. Each permanent magnet cylinder 601 has a gear 603 coaxially fixed on its rotating end. The gears 603 on adjacent permanent magnet cylinders 601 mesh with each other, so that a single motor 602 can drive multiple permanent magnet cylinders 601 to rotate through the meshing between the gears 603. The rotating permanent magnet cylinders 601 can make the entire cylinder surface rotate continuously, contacting the waste debris falling from above, increasing the magnetic adsorption of more cylinder surface and waste debris, and increasing the adsorption amount.

[0053] For specific details, please refer to Figure 4 and Figure 5 The solid-liquid separation structure 8 includes a filter plate 801, a sealing door 802, and an outlet valve pipe 803.

[0054] The filter plate 801 is fixed in the lower part of the cleaning box 5, below the magnetic chip collection assembly 6. The filter plate 801 divides the cleaning box 5 into upper and lower chambers. The upper chamber of the filter plate 801 is used to filter out solid waste chips. The filter plate 801 is provided with several filter holes. The rinsing liquid drawn into the cleaning box 5 by the pump passes through the filter holes of the filter plate 801 and is filtered into the lower chamber of the filter plate 801 for collection, thus achieving solid-liquid separation.

[0055] The cleaning box 5, located above the filter plate 801, has an openable and closable sealed door 802 on its wall. When chip collection stops, the operator can open the sealed door 802 to collect the waste chips from the filter plate 801 and the permanent magnet cylinder 601. A water outlet valve 803 is located at the bottom of the cleaning box 5. When chip collection stops, the operator can open the valve on the water outlet valve 803 to drain the flushing liquid from the bottom of the cleaning box 5.

[0056] Furthermore, in actual work, because the entire working space inside the milling machine is relatively large (because it is necessary to mill some workpieces with large volumes), the area that the suction head 4 needs to suction chips is much larger than the opening size of the suction nozzle 401. Therefore, in this embodiment, in order to quickly collect and clean the waste chips on the entire surface of the chip collection plate 1, the chip sweeping assembly 9 is also equipped with a displacement assembly, which is used to drive the chip sweeping end and the suction nozzle 401 that is snapped on the chip sweeping end to move, so as to collect waste chips on the larger surface of the chip collection plate 1.

[0057] The chip removal assembly 9 includes a chip removal end and a displacement assembly.

[0058] For specific details, please refer to Figures 2-5 The chip removal end includes a shaft 901, a brush 902, a bearing 903, and a motor 906.

[0059] The displacement assembly includes slider 904 and linear module 905.

[0060] The shaft 901 is horizontally inserted through the chip collection plate 1 and slides along the surface of the chip collection plate 1. One end of the shaft 901 is rotatably mounted on the slider 904. A second motor 906 is fixed on the slider 904. The main shaft of the second motor 906 is fixedly connected to the shaft 901, thereby driving the shaft 901 to rotate. Several brushes 902 are fixed on the shaft 901. When the shaft 901 drives the brushes 902 to rotate, the ends of the brushes 902 will contact the surface of the chip collection plate 1 and sweep up the waste chips.

[0061] Since the waste chips are generally metal chips, which are relatively sharp, the brush 902 experiences higher friction and wear when sweeping them. Therefore, the brush 902 is made of nylon or copper wire to increase its wear resistance and extend its service life.

[0062] The slider 904 is fixed on the displacement platform of the linear module 905, which is fixed inside the milling machine. This causes the shaft 901 on the slider 904 to slide along the surface of the chip collection plate 1, and the rotating brush 902 on the shaft 901 is used to sweep the chips off the entire surface of the plate.

[0063] The shaft 901 is coaxially fixed with bearings 903 at both ends. The suction nozzle 401 is provided with slots at both ends, which can be directly inserted into the bearings 903 for matching. Magnetic blocks are also fixed in the slots, which allows the suction nozzle 401 to be quickly magnetically attached to the shaft 901, so that the suction nozzle 401 moves synchronously with the shaft 901, and the swept waste is promptly pumped and collected. The bearings 903 prevent the suction nozzle 401 from rotating with the shaft 901, reducing interference.

[0064] It is worth noting that after milling is completed, the suction nozzle 401 will move along with the shaft 901 to perform chip suction. At this time, the telescopic tube 403 will also extend or retract, so that the suction nozzle 401 is always connected to the cleaning box 5.

[0065] In order to ensure the normal use of the chip removal assembly 9 installed on itself, the chip collection plate 1 includes a cavity plate 101, a slide groove 102, and a baffle 103.

[0066] Specifically, the cavity plate 101 is fixed to the bottom of the milling machine. The cavity plate 101 is provided with a chip collection groove with the opening facing upwards to facilitate the falling of waste chips into the chip collection groove. A sliding groove 102 is passed through the side groove surface of the chip collection groove. A shaft 901 is slidably arranged in the sliding groove 102 and slides along the groove surface of the chip collection groove through the sliding groove 102. A linear module 905 is also fixed on one side outer wall of the cavity plate 101. A baffle 103 is fixedly connected to the outer wall of the cavity plate 101 on this side. The baffle 103 blocks the upper part of the entire linear module 905 to reduce the occurrence of waste chips entering the linear module 905. The surface of the baffle 103 is inclined, and the inclined end faces the chip collection groove to facilitate the collection of waste chips.

[0067] Example 2

[0068] During the milling process, some of the waste chips are in the form of fine powder. When the milling machine uses airflow to remove these chips, the powdery chips are scattered throughout the milling machine chamber. When these chips are subsequently sucked into the cleaning box 5 using the suction head 4, the smaller cleaning box 5 also becomes filled with floating powdery chips. When these powdery chips fill a small, enclosed space, static electricity, electrical sparks from the equipment, or even high temperatures from friction can easily cause an explosion (similar to explosions in flour mills and hardware factories). Therefore, in this embodiment, the pump suction assembly 7 also includes a component for absorbing the powdery chips.

[0069] For specific details, please refer to Figure 3 and Figure 5 The pump suction assembly 7 includes a dust collection chamber 701, a dust filter 702, and a fan 703.

[0070] The dust collection chamber 701 is connected to the upper part of the cleaning box 5. The inlet of the dust collection chamber 701 corresponds to the opening of the telescopic pipe 403, and the outlet of the dust collection chamber 701 is connected to the pump end of the fan 703. The fan 703 is fixed outside the cleaning box 5, so that the powdery waste in the telescopic pipe 403 can be quickly sucked into the dust collection chamber 701, while the heavier granular waste will fall directly to the lower part of the cleaning box 5 and will not enter the dust collection chamber 701. A dust filter 702 is fixedly installed at the inlet of the dust collection chamber 701 to intercept the powdery waste sucked into the dust collection chamber 701 and reduce the occurrence of powdery waste floating everywhere in the cleaning box 5.

[0071] The dust filter 702 has a cylindrical structure to facilitate the collection and storage of more powdery waste.

[0072] It is worth noting that the top surface of the cleaning box 5 is equipped with an openable and closable sealing cover. When the dust collection stops, the sealing cover can be opened manually to replace the dust filter 702 located in the upper part of the cleaning box.

[0073] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
