Description

Technical Field

[0001] This utility model relates to an auxiliary processing device, and more particularly to a chip removal and dust prevention device for a processing machine. Background Technology

[0002] During machining, the cutting tool and the workpiece rotate and move relative to each other, which raises the temperature of both. To prevent the workpiece from being damaged by the high temperature during machining, cutting fluid is sprayed in during machining. In addition to reducing the temperature during machining, it can also wash away the chips on the worktable and maintain good machining quality.

[0003] However, regardless of whether the cutting fluid is supplied via a central water outlet or an external spray, it will inevitably splash, causing dirt to be generated in the machining area. The dust and chips scattered in the air will also cause environmental pollution and have adverse effects on human health. Therefore, there is still room for improvement in reducing pollution.

[0023] See Figure 1 , Figure 2 , Figure 3 An embodiment of the present invention for a chip removal and dust prevention device for a processing machine is applicable to a processing machine 8, the processing machine 8 being used to process a workpiece 9, and including a movable worktable 81 and a cutting tool 82 for processing the workpiece 9 and moving relative to the worktable 81. The chip removal and dust prevention device for the processing machine includes a fixture unit 2 and a filter unit 3.

[0024] It should be noted that, in this embodiment, the cutting tool 82 is suitable for providing cutting fluid in a center-outlet manner. In other embodiments, cutting fluid can also be provided in an external spray manner, and is not limited thereto.

[0025] See Figure 3 , Figure 4 , Figure 5 The fixture unit 2 is disposed on the machining machine 8 and can move relative to the cutting tool 82, and is suitable for placing the workpiece 9. The fixture unit 2 includes a base 21 disposed on the worktable 81, a support seat 22 disposed on the base 21, a vacuum seat 23 disposed on the support seat 22 and suitable for placing the workpiece 9, a transition seat disposed on the support seat 22, and an outer ring seat 24 disposed on the support seat 22 and surrounding the vacuum seat 23.

[0026] See Figure 4 , Figure 5 , Figure 6 The base 21 has a first circular vent 211 formed on the top surface, a circular positioning groove 212 formed on the top surface at a distance from the first vent 211, and a venting channel 213 formed on the bottom surface that spatially connects the first vent 211 and the positioning groove 212. The circular area of ​​the positioning groove 212 is larger than the circular area of ​​the first vent 211. The projected area of ​​the venting channel 213 in the vertical direction Z partially overlaps the first vent 211 and the positioning groove 212.

[0027] The support base 22 is cylindrical and installed in the positioning groove 212. The support base 22 has an embedding portion 221, a first annular surface 222, a second annular surface 223, a third annular surface 224, a fourth annular surface 225, and a communicating hole 226. The embedding portion 221 is formed on the bottom side and extends downwards from the bottom surface, embedding itself into the positioning groove 212. The first annular surface 222, the second annular surface 223, the third annular surface 224, and the fourth annular surface 225 are spaced apart from bottom to top along the vertical direction Z, forming concentric circles with progressively smaller outer diameters. The communicating hole 226 extends along the vertical direction Z and penetrates the fourth annular surface 225 and the embedding portion 221. The communicating hole 226 communicates with the air guide channel 213 and the first air outlet 211 through the positioning groove 212.

[0028] See Figure 3 , Figure 4 and Figure 6 The suction seat 23 abuts against the third annular surface 224 and the fourth annular surface 225. The outer periphery of the suction seat 23 protrudes from the third annular surface 224 and is spaced apart from the second annular surface 223. The suction seat 23 has a main air inlet 231 that runs through both the top and bottom sides in the vertical direction Z, a plurality of extension holes 232 that are spaced at an angle around an axis L passing through the center and open on the circumferential side, a plurality of secondary air inlets 233 formed on the top surface and extending downward to connect with the extension holes 232, and a plurality of clamping grooves 234 formed on the top surface and spaced at an angle around the axis L. The main air inlet 231 connects the extension holes 232, the connecting hole 226, the positioning groove 212, the air guide channel 213 and the first air outlet 211. The main air inlet 231 is open to the outside. The extension holes 232 extend radially outward from the main air inlet 231. The clamping groove 234 extends radially outward from the center and is suitable for setting a clamp (not shown) for fixing the workpiece 9.

[0029] See Figure 4 , Figure 6 , Figure 7 The outer ring seat 24 is disposed on the first annular surface 222 of the support seat 22. The outer ring seat 24 has an annular body 241, a tube 242 extending outward from the annular body 241, and a second vent 243 extending from the annular body 241 to the tube 242. The inner surface of the annular body 241 is concave and, together with the suction seat 23 and the second annular surface 223 of the support seat 22, defines an annular space 244 communicating with the second vent 243. The annular space 244 forms a gap 245 between the outer ring seat 24 and the suction seat 23, aligning with the extension hole 232.

[0030] In other embodiments, there may be two or more first air outlets 211, and the air guide channel 213 may be multiple interconnected deep holes, without limitation.

[0031] The filter unit 3 is connected to the first air outlet 211 and the second air outlet 243, and provides negative pressure to draw air towards the workpiece 9, filtering the fluid before discharging it. More specifically, the filter unit 3 includes multiple filter elements 31 for filtering fluid, a blower assembly 32 for generating negative pressure, and multiple pipes 33. Two of the pipes 33 are respectively connected to the first air outlet 211 and the second air outlet 243, while the other pipes 33 connect to the filter elements 31 and the blower assembly 32. The blower assembly 32 generates negative pressure and draws air through the pipes 33, which is then filtered by the filter elements 31 before being discharged to the outside. The filter elements 31 are partially connected between the blower assembly 32 and the fixture unit 2, and partially connected between the blower assembly 32 and the outside.

[0032] During operation, the hollow cylindrical workpiece 9 is positioned on the suction seat 23, with the bottom surface of the workpiece 9 aligned with the main air inlet 231. When machining the inner surface of the workpiece 9, cutting fluid mixed with air, chips, and dust is drawn in through the main air inlet 231, and enters the filter unit 3 through the connecting hole 226, the positioning groove 212, the air guide channel 213, and the first air outlet 211. The auxiliary air inlet 233 can draw in fluid that has not entered the main air inlet 231 and the chips and dust mixed therein from the outside of the workpiece 9, and enters the annular space 244 through the gap 245 after passing through the extension hole 232, and then exits through the second air outlet 243 (see...). Figure 7 The air, mixed with dust, chips, and cutting fluid, enters the filter unit 3. Before passing through the blower assembly 32, the air passes through part of the filter element 31 to filter out larger dust and chips. The relatively clean fluid then passes through another part of the filter element 31 after entering the blower assembly 32 before being discharged. This process not only keeps the processing area clean but also filters out contaminants such as chips, dust, and suspended particles that have entered the filter unit 3 before being discharged to the outside, achieving zero carbon emissions or even negative carbon emissions. The discharged air can also be used to drive a wind turbine to generate electricity.

[0033] Compared to existing processing machines, this invention provides negative pressure through the blower unit 32 and the fixture unit 2 to draw the workpiece 9. Chips and dust, along with air and cutting fluid, are drawn out through the pipe 33, reducing dust and pollution in the processing area. The fluid is then filtered through the filter element 31 before being discharged, reducing dust and suspended particles discharged into the outside world, thereby improving product yield and reducing pollution.

[0034] In conclusion, the chip removal and dust prevention device for processing machines of this utility model can indeed achieve the purpose of this utility model.
