[0064] The following is combined Figures 1-9 This invention describes a dust collection device for polishing and a CNC machine tool.

[0065] According to an embodiment of this application, a dust collection device 500 for polishing is provided. Please refer to... Figures 1 to 3 The polishing dust collection device 500 includes: a device body 1, a polishing assembly, a wheel waxing assembly, a polishing cloth wheel 2, and a dust collection port switching assembly 40. The device body 1 has an independent polishing working chamber 10 and a wheel waxing working chamber 20. The device body 1 has a first dust collection port 43 and a second dust collection port 44. The first dust collection port 43 is connected to the polishing working chamber 10, and the second dust collection port 44 is connected to the wheel waxing working chamber 20. The polishing assembly is located in the polishing working chamber 10. The wheel waxing assembly is located in the wheel waxing working chamber 20. The polishing cloth wheel 2 is adapted to switch between the polishing working chamber 10 and the wheel waxing working chamber 20. The dust collection port switching assembly 40 is connected to the device body 1 and is used to control the opening and closing of the first dust collection port 43 and the second dust collection port 44 to achieve separate dust collection of the polishing working chamber 10 and the wheel waxing working chamber 20.

[0066] According to the polishing dust collection device 500 of the present application embodiment, the polishing working chamber 10, in conjunction with the polishing cloth wheel 2, can start the polishing of the workpiece 4 to be processed on the polishing working chamber 10. Then, the polishing cloth wheel 2 is trimmed and waxed by the wheel dressing and waxing working chamber 20. The opening and closing of the first dust collection port 43 and the second dust collection port 44 are switched by the dust collection port switching component 40, so as to complete the separate dust collection and recycling of the polishing working chamber 10 and the wheel dressing and waxing working chamber 20, reduce safety risks, prevent manual inhalation of dust, further protect the health of the workers, and ultimately achieve the environmental protection requirements of green manufacturing.

[0067] Understandably, the independent polishing chamber 10 and the wheel dressing and waxing chamber 20 effectively prevent the dust generated during the polishing process from contaminating each other with the wax debris that may be generated during the wheel dressing and waxing process, thus ensuring processing quality and equipment cleanliness.

[0068] During the polishing process, a large amount of dust and debris is generated. The dust extraction port switching component 40 ensures that when polishing is being performed in the polishing chamber 10, the first dust extraction port 43 is open and effectively extracts dust; while when the wheel dressing and waxing chamber 20 is being used for finishing and waxing, the second dust extraction port 44 is open and also effectively extracts dust. This design not only improves dust extraction efficiency but also prevents dust accumulation inside the device, reducing safety risks.

[0069] The suction port switching assembly 40 can precisely control the opening and closing of the first suction port 43 and the second suction port 44, ensuring that the suction operation of each working chamber can be carried out independently. It can flexibly adjust the suction area according to actual processing needs, thereby improving the suction effect of the polishing working chamber 10 and the wheel dressing and waxing working chamber 20 and preventing dust diffusion. There is no need to add additional suction equipment or use a vacuum cleaner 700 with a larger air volume, reducing equipment purchase and maintenance costs.

[0070] In one embodiment, please refer to Figures 1 to 5 The polishing assembly includes a special clamp 3, which is located inside the polishing working chamber 10 and is used to hold the workpiece 4 to be processed. A polishing cloth wheel 2 is located in the polishing working chamber 10 and is used to polish the workpiece 4. The polishing cloth wheel 2 is also located in the wheel dressing and waxing working chamber 20, where the wheel dressing and waxing assembly is used to trim the outline of the polishing cloth wheel 2 and apply wax.

[0071] According to one embodiment of this application, the device body 1 includes a dust suction channel 30 and a dust discharge port. The dust discharge port connects the dust suction channel 30 and the polishing working chamber 10. The outlet of the dust suction channel 30 is a first dust suction port 43. The first dust suction port 43 and the second dust suction port 44 are located on the same side of the device body 1.

[0072] When the polishing dust collection device 500 is connected to a vacuum cleaner 700, the dust generated in the polishing working chamber 10 first passes through the dust discharge port and then reaches the first dust collection port 43 along the dust collection channel 30. The first dust collection port 43 and the second dust collection port 44 are located on the same side of the device body 1, which reduces the switching difficulty of the dust collection port switching component 40. The "switching difficulty" can be understood as the complexity of the dust collection port switching component 40 in terms of operation, maintenance and technical implementation.

[0073] For example, since the first suction port 43 and the second suction port 44 are located on the same side of the device body 1, the suction port switching assembly 40 can use a simpler mechanical structure (such as a sliding valve or a rotary baffle) to open and close the first suction port 43 and the second suction port 44. This design not only reduces the manufacturing cost of the equipment but also improves the reliability of the switching operation. On the other hand, the same-side arrangement of the suction ports allows the switching of the first suction port 43 and the second suction port 44 to be completed in the same position without moving the equipment or adjusting the connection position of the vacuum cleaner 700.

[0074] According to one embodiment of this application, please refer to Figures 1 to 5 The main body 1 of the device includes a polishing box 14, a wheel dressing box 21, and a dust collection box 31. The polishing box 14 has a polishing working chamber 10 inside and a dust discharge port. The wheel dressing box 21 has a wheel dressing and waxing working chamber 20 inside and a second dust collection port 44. The dust collection box 31 has a dust collection channel 30 inside and a first dust collection port 43. The polishing box 14 is connected to the wheel dressing box 21, and the dust collection box 31 is connected to the polishing box 14. The dust collection box 31 is located on the same side of the polishing box 14 and the wheel dressing box 21.

[0075] The polishing box 14 has a polishing working chamber 10 inside, which is used to accommodate the polishing components and polishing cloth wheel 2 for polishing the workpiece 4. The polishing box 14 has a dust exhaust port for discharging the dust generated during the polishing process. The dust exhaust port is connected to the dust suction channel 30 in the dust collection box 31 to ensure that the dust can be discharged quickly and efficiently, and to prevent the dust from accumulating in the polishing working chamber 10.

[0076] The wheel dressing box 21 has a wheel dressing and waxing working chamber 20 inside, which is used to accommodate the wheel dressing and waxing components for trimming the shape and applying wax to the polishing cloth wheel 2. The wheel dressing box 21 has a second dust suction port 44 for discharging dust and wax debris generated during the wheel dressing and waxing process. The wheel dressing box 21 is connected to the polishing box 14, allowing the polishing cloth wheel 2 to quickly switch between the polishing working chamber 10 and the wheel dressing and waxing working chamber 20, thus improving work efficiency.

[0077] The dust collection box 31 has a dust collection channel 30 inside, which is used to collect and guide the dust discharged from the polishing box 14 and the wheel dressing box 21 to the dust collection device. The dust collection box 31 has a first dust collection port 43 for connecting an external vacuum cleaner 700 to achieve centralized collection and treatment of dust. The dust collection box 31 is located on the same side of the polishing box 14 and the wheel dressing box 21, so that the first dust collection port 43 and the second dust collection port 44 can be located on the same side of the main body 1 of the device, reducing the difficulty of switching the dust collection port switching component 40.

[0078] According to one embodiment of this application, please refer to Figures 1 to 5 The main body 1 of the device includes a front door 32 for vacuuming, a cleaning port at the front end of the vacuum box 31, the cleaning port is connected to the vacuuming channel 30, and the front door 32 for vacuuming can be opened and closed and is located at the cleaning port.

[0079] A front door 32 is located at the front end of the dust collection box 31 and is used to cover the cleaning port. The front door 32 has an openable / closable design, allowing the operator to open or close the cleaning port as needed. When closed, the front door 32 effectively seals the cleaning port, preventing dust leakage and ensuring the safe operation of the equipment. When open, the operator can easily remove dust and debris from the suction channel 30. According to one embodiment of this application, the main body 1 of the device includes a guide plate 33, which is partially located in the polishing working chamber 10. The opening of the guide plate 33 gradually decreases along the direction towards the dust discharge port.

[0080] The main function of the air guide plate 33 is to guide the dust airflow generated in the polishing working chamber 10 toward the dust discharge port. Through the design of the air guide plate 33, the dust airflow can be effectively controlled, avoiding disorderly diffusion in the working chamber, thereby improving dust collection efficiency.

[0081] The opening of the air guide plate 33 gradually decreases along the direction towards the dust outlet. This design can accelerate the airflow speed, form a certain negative pressure area, and further enhance the dust collection effect.

[0082] According to one embodiment of this application, please refer to Figures 1 to 5 The main body 1 of the device includes a polishing box 14, and the polishing box 14 has a polishing working chamber 10 inside. The polishing components include a worktable 11, a dust baffle 12 and a special fixture 3. The worktable 11 is connected to the polishing box 14, and the special fixture 3 is connected to the worktable 11. The special fixture 3 is used to hold the workpiece 4 to be processed. The dust baffle 12 is connected to the polishing box 14 and is located above the worktable 11. A gap is formed between the dust baffle 12 and the worktable 11.

[0083] The polishing box 14 has a polishing working chamber 10 inside, which is used to accommodate the polishing components and polishing cloth wheel 2 for polishing the workpiece 4. The worktable 11 is connected to the polishing box 14, and the special fixture 3 is connected to the worktable 11 to hold the workpiece 4 and ensure its stability during the polishing process.

[0084] The dust baffle 12 is connected to the polishing box 14 and is located above the worktable 11. It can block the dust and debris generated during the polishing process from flying upwards and prevent them from polluting the working environment. A gap is provided between the dust baffle 12 and the worktable 11 so that the dust generated during the polishing process can be guided to the dust discharge port through the gap, which further optimizes the dust collection and discharge efficiency.

[0085] According to one embodiment of this application, the polishing box 14 is provided with a replacement port, and the polishing assembly includes a polishing front door 13, which is openable and closable and located at the replacement port.

[0086] Understandably, the replacement port is located on the polishing box 14 for convenient replacement of the polishing cloth wheel 2. Through the replacement port, the operator can quickly and easily replace the workpiece 4 to be processed without disassembling the entire polishing box 14 or the polishing assembly, which significantly simplifies the replacement operation.

[0087] According to one embodiment of this application, please refer to Figures 1 to 5 The main body 1 of the device includes a wheel dressing box 21, and the wheel dressing box 21 is provided with a wheel dressing and waxing working chamber 20. The wheel dressing and waxing assembly includes a wheel dressing cutter 22, polishing wax 23, a wheel dressing cutter bracket 24, and a polishing wax bracket 25.

[0088] Understandably, the wheel dressing box 21 has a wheel dressing and waxing working chamber 20 inside, which is used to accommodate the wheel dressing and waxing components to dress and wax the polishing cloth wheel 2. The closed design of the wheel dressing box 21 makes the wheel dressing and waxing operations more centralized and reduces the impact of the external environment on the wheel dressing and waxing process.

[0089] The dressing tool 22 is used to trim the outline of the polishing cloth wheel 2 to ensure its surface is flat, thereby improving the polishing effect. The polishing wax 23 is used to wax the polishing cloth wheel 2, increasing its surface lubrication and polishing effect, and extending the service life of the polishing cloth wheel 2.

[0090] According to one embodiment of this application, the wheel dressing and waxing assembly includes a wheel dressing front viewing window 26, which is connected to the wheel dressing box 21. The wheel dressing front viewing window 26 is located at the front end of the wheel dressing box 21 for convenient observation of the wheel dressing and waxing operation process. Through the wheel dressing front viewing window 26, the operator can visually monitor the usage of the wheel dressing tool 22 and polishing wax 23, ensuring the accuracy and efficiency of the operation. The wheel dressing front viewing window 26 is typically made of a highly transparent material (such as tempered glass or polycarbonate) to ensure that the operator can clearly observe the internal conditions.

[0091] According to one embodiment of this application, the wheel dressing and waxing assembly includes a wheel dressing baffle 27, which is detachably connected to the wheel dressing box 21 and is located on the side of the wheel dressing and waxing working chamber 20 near the polishing working chamber 10.

In the second state, the switching slide plate 46 extends and blocks the first vacuum port 43. At the same time, the opening on the switching slide plate 46 is connected to the second vacuum port 44, so that the opening connects the second vacuum port 44 and the outlet, and the first vacuum port 43 is disconnected from the outlet.

[0095] According to the polishing suction port switching unit of this application embodiment, by controlling the sliding of the switching slide plate 46, the polishing suction port switching unit can concentrate the suction airflow in one area (such as the polishing area or the wheel dressing and waxing area), thereby improving the suction effect in that area and preventing dust diffusion. No additional suction equipment or a vacuum cleaner 700 with a larger airflow is required, reducing equipment purchase and maintenance costs. The drive component 45 enables rapid switching of the suction port, making operation simple and allowing for flexible adjustment of the suction area according to actual processing needs. This effectively collects dust, reduces environmental pollution, lowers the risk of dust inhalation for operators, and protects their health.

[0096] It is understood that the suction port switching box 41 is internally equipped with an outlet, a first suction port 43, and a second suction port 44. The outlet is used to connect to the vacuum cleaner 700 or the suction hose of the vacuum cleaner 700. Specifically, it can be connected to the internal suction hose 50 via an adapter 42, and then connected to the vacuum cleaner 700 via the internal suction hose 50. The first suction port 43 and the second suction port 44 are used to collect dust generated in different areas. In one embodiment, one of the first suction port 43 and the second suction port 44 is configured to correspond to the polishing working chamber 10, and the other is configured to correspond to the waxing working chamber 20.

[0097] The switching slide plate 46 is slidably connected to the inside of the suction port switching box 41. It has an opening, the shape of which is adapted to the shape of the second suction port 44. When the metal frame of the mobile phone is polished, the switching slide plate 46 slides to the first state, the switching slide plate 46 retracts, the switching slide plate 46 no longer blocks the first suction port 43, and at the same time the opening is not aligned with the second suction port 44, so that the dust in the polishing area enters the suction port switching box 41 through the first suction port 43 and is transported to the vacuum cleaner 700 through the outlet; at this time, the second suction port 44 is disconnected from the outlet, improving the suction efficiency of the first suction port 43.

[0098] When the polishing cloth wheel 2 is being repaired and waxed, the switching slide plate 46 slides to the second state and extends, aligning the opening with the second suction port 44. At the same time, the other parts of the switching slide plate 46 cut off the connection between the first suction port 43 and the outlet, allowing the dust from the wheel repair and waxing area to enter the suction port switching box 41 through the second suction port 44 and be transported to the vacuum cleaner 700 through the outlet. At this time, the first suction port 43 is disconnected from the outlet, improving the suction efficiency of the second suction port 44.

[0099] The drive assembly 45 is used to drive the sliding of the switching slide plate 46, and can be a motor, cylinder or other power device.

[0100] According to one embodiment of this application, an adapter 42 is included, with a first end of the adapter 42 rotatably connected to an outlet and a second end of the adapter adapted to install an internal dust suction pipe 50.

[0101] Understandably, the internal suction pipe 50 is a pipe used to transport dust, connecting the suction port switching box 41 and the vacuum cleaner 700, and delivering the collected dust to the vacuum cleaner 700 for processing. The rotating connection design of the adapter 42 allows the installation angle of the internal suction pipe 50 to be flexibly adjusted to adapt to different vacuum cleaners 700 or work sites.

[0102] According to one embodiment of this application, the first end of the adapter 42 can be rotated along the outlet angle to a preset angle, the preset angle being 30° to 60°.

[0103] It should be noted that the angle at which the first end of the adapter 42 can rotate along the outlet to the preset angle refers to the maximum angle at which the adapter 42 can rotate. In one embodiment, the angle at which the adapter 42 can rotate along the outlet is 40°. The adapter 42 can rotate at 0°, 10°, 20°, 30°, and 40° to adapt to different vacuum cleaners 700 or work sites.

[0104] According to one embodiment of this application, a drive cover plate 47 is included. The drive cover plate 47 is connected to a vacuum port switching box 41, and a receiving space is formed between the drive cover plate 47 and the vacuum port switching box 41. A switching slide plate 46 and a drive assembly 45 are disposed in the receiving space.

[0105] The space formed between the drive cover 47 and the suction port switching box 41 can effectively prevent dust leakage and ensure the suction effect.

[0106] In one embodiment, the drive cover 47 is a plate-like structure. The accommodating space is enclosed by the drive cover 47 and the inner wall of the suction port switching box 41. When the drive assembly 45 is working, the drive switching slide plate 46 slides within the accommodating space to control the communication state between the opening and the first suction port 43 or the second suction port 44.

[0107] In one embodiment, the drive cover 47 is fixed to one side of the vacuum port switching box 41 by bolts, snaps or other connection methods to form a closed receiving space.

[0108] According to one embodiment of this application, the dust extraction port switching box 41 is provided with an observation window for observing the dust accumulated inside the containment space. Through the observation window, the operator can intuitively view the dust accumulation inside the containment space and clean it in a timely manner to avoid excessive dust affecting the operation of the equipment.

[0109] The observation window is a transparent window, which can be made of tempered glass or high-strength plastic. The observation window is set on the vacuum port switching box 41 or the drive cover plate 47. Specifically, it can be fixedly connected to the vacuum port switching box 41 or the drive cover plate 47, or it can be detachably connected to at least one of the vacuum port switching box 41 and the drive cover plate 47.

The design of the filter box 61 enables centralized filtration of dust, ensuring that the emitted air meets environmental protection requirements.

[0113] The filter screen 65 is located inside the filter box 61, between the filter inlet 62 and the filter outlet 63. It effectively captures dust and debris carried in the suction pipe, ensuring filtration efficiency. The filter screen 65 can be made of high-efficiency filter materials (such as HEPA filters or bag filters) to intercept fine dust particles. Of course, the filter screen 65 can also be made of other materials, which will not be elaborated here.

[0114] The filter window 64 is an openable cover located at the cleaning port, allowing operators to easily observe the condition of the filter screen 65 and clean or replace it in a timely manner.
