[0002] In the process of machining workpieces by a numerical control machine tool, in order to timely and effectively remove various chips generated in the cutting process and ensure the cleanliness of the machining area, a chip removal device is usually arranged below the machining table of the numerical control machine tool to collect the cutting chips and cooling liquid generated in the machining process of the machine tool and separate the waste chips and the cooling liquid, so that the cooling liquid can be reused and the chips can be timely and effectively removed.

[0003] In the prior art, the chip removal device usually uses filter plates to filter and separate the chips and the cooling liquid.

[0039] The left side wall of the collection rack 1 and close to the filter plate 11 is provided with a chip discharge opening 13, the left side of the collection rack 1 is provided with an inclined chip box 14, the bottom of the chip box 14 is connected with a conveying frame 9, the right side of the conveying frame 9 is welded and fixed with a discharge frame 91, the inside of the conveying frame 9 is mounted with a conveying belt 92, the front side of the conveying frame 9 is mounted with a third motor 921 for driving the conveying belt 92 to operate, the bottom of the stand 2 is welded and fixed with a waste liquid tank 21, the inside of the stand 2 is provided with a magnetic attraction cavity 22 and a collection cavity 23, the collection cavity 23 is arranged below the magnetic attraction cavity 22 and communicates with the waste liquid tank 21, the right side of the waste liquid tank 21 is provided with a recovery pipe 211, the bottom end of the recovery pipe 211 penetrates through the side wall of the waste liquid tank 21 and extends into the inside of the waste liquid tank 21, the bottom of the recovery pipe 211 and inside the waste liquid tank 21 is mounted with a pump body 212.

[0040] In use, the collection rack 1 collects the chips and cooling liquid generated by the numerical control machine tool, the two groups of filter plates 11 arranged in the collection rack 1 are used for preliminary filtering, the larger chips are filtered by the filter plates 11 and discharged outward to the inside of the chip box 14 through the chip discharge opening 13, then fall on the conveying belt 92 and are discharged outward, the cooling liquid mixed with the chip powder falls into the settling column 3 through the conveying hopper 12 and flows downward in the settling column 3, at the same time, the magnetic attraction mechanism operates to make the settling column 3 magnetically attract the chip powder in the cooling liquid and attach the chip powder on the inner wall of the settling column 3, the cooling liquid flows to the bottom end of the settling column 3, is blocked by the sealing mechanism and flows to the collection cavity 23 through the liquid outlet hole 32 of the settling column 3, then flows to the inside of the waste liquid tank 21 through the collection cavity 23 for recycling, the pushing ring 5 is driven to reciprocate by the driving mechanism, the pushing ring 5 pushes the chips attached to the settling column 3 to the bottom end, and the sealing frame 6 is pressed downward to make the chips fall into the inside of the conveying pipe 7, then can be discharged outward through the conveying pipe 7.

[0041] As shown, Figures 4-6As shown, the magnetic attraction mechanism is arranged on the inner side of the magnetic attraction cavity 22, and comprises a plurality of evenly distributed electromagnets 31 mounted on the outer wall surface of the settling column 3. A protective cover 311 is arranged on the outer wall of the settling column 3 and located on the outer side of the electromagnets 31, which protects the electromagnets 31. A plurality of evenly distributed liquid outlet holes 32 are arranged on the side wall of the settling column 3 and located on the inner side of the collection cavity 23. A connecting ring 33 is welded and fixed to the bottom of the settling column 3.

[0042] The settling column 3 is made of a metal material with good magnetic conductivity. When the electromagnets 31 are in operation, the settling column 3 can generate magnetism and magnetically attract the debris powder on the inner side of the settling column 3, so that the debris powder adheres to the inner wall surface of the settling column 3, thereby separating the debris powder from the cooling liquid.

[0043] The top of the guide column 4 is provided with an upper support 41, and the bottom of the guide column 4 is provided with a lower support 42. The upper support 41 and the lower support 42 are both welded and fixed to the inner wall of the settling column 3. The outer side of the guide column 4 is provided with a spiral blade 43. The upper and lower ends of the spiral blade 43 are respectively welded and fixed to the upper support 41 and the lower support 42. The inner and outer edges of the spiral blade 43 have gaps with the outer wall surface of the guide column 4 and the inner wall surface of the settling column 3, respectively. The side wall of the guide column 4 is provided with a spiral slide 44.

[0044] When the cooling liquid falls into the interior of the settling column 3, the cooling liquid can flow downward along the spiral blade 43, and under the action of centrifugal force, the cooling liquid and the debris powder gradually approach the inner wall edge of the settling column 3, thereby improving the magnetic attraction efficiency of the debris powder and the discharge efficiency of the cooling liquid. Due to the existence of the inner and outer edges of the spiral blade 43, the gap between the inner edge of the spiral blade 43 and the outer surface of the guide column 4 can generate convection air at the inner edge of the spiral blade 43, which facilitates the blowing of part of the debris powder. The gap between the outer edge of the spiral blade 43 and the inner surface of the settling column 3 facilitates the up-and-down movement of the pushing ring 5 and the pushing of the debris powder adhering to the inner surface of the settling column 3.

[0045] The driving mechanism comprises a double-output shaft motor 45 and a reciprocating screw rod 46. The double-output shaft motor 45 is installed on the top of the upper support 41, and a protective shell 451 is arranged on the upper support 41 and located on the outer side of the double-output shaft motor 45. The reciprocating screw rod 46 is arranged below the upper support 41 and coaxially driven with the lower output shaft of the double-output shaft motor 45. The upper side of the double-output shaft motor 45 is provided with a diffusion cone 47 coaxially driven with the upper output shaft of the double-output shaft motor 45. The conical surface of the diffusion cone 47 is provided with an annular array of arc-shaped strips 471.

[0046] When the double-output shaft motor 45 operates, the reciprocating screw rod 46 and the diffusion cone 47 can be driven to rotate simultaneously. When the diffusion cone 47 rotates, the arc-shaped strip 471 is matched to guide the cooling liquid falling into the inside of the settling column 3 to diffuse uniformly in all directions, so that the cooling liquid falls on the spiral blade 43 to flow.

[0047] The outer surface of the pushing ring 5 is in contact with the inner wall surface of the settling column 3, and the bottom of the pushing ring 5 is provided with an annular array of scrapers 51. The pushing ring 5 and the scraper 51 are both made of non-magnetic alloy material without magnetic conductivity, so that the pushing ring 5 and the scraper 51 do not generate magnetic induction under the action of the magnetic field, facilitating the pushing of the adhering debris powder on the settling column 3. The lifting block 52 is slidingly arranged on the outside of the reciprocating screw rod 46 and is slidingly connected with the guide column 4. The upper and lower ends of the lifting block 52 are both provided with a limiting block 521, and the inner wall of the guide column 4 is provided with a limiting groove corresponding to the limiting block 521. The limiting block 521 slides up and down along the limiting groove to limit the lifting block 52, avoiding the rotation of the reciprocating screw rod 46 driving the lifting block 52, thereby ensuring the reciprocating movement of the lifting block 52 up and down in the guide column 4.

[0048] The movable ring 53 is arranged on the lifting block 52 and is rotatably connected with the lifting block 52. The outer side of the movable ring 53 is welded with a plurality of connection rods 531 arranged in a spiral shape. The connection rod 531 is slidingly connected between the spiral slide 44 and the inner wall of the pushing ring 5. The spiral slide 44 is located at the middle position between the adjacent tangent points of the spiral blade 43, so that the connection rod 531 has a large distance from the upper and lower surfaces of the spiral blade 43.

[0049] When the reciprocating screw rod 46 is driven to rotate by the double-output shaft motor 45, the lifting block 52 drives the movable ring 53 to move downward under the limiting action of the limiting block 521, and at the same time, the connection rod 531 slides along the spiral slide 44, so that the movable ring 53 drives the pushing ring 5 to rotate in the process of moving downward, and the pushing ring 5 drives the scraper 51 to rotate, so that the scraper 51 scrapes the debris powder adhering to the inner wall surface of the settling column 3 and continuously pushes it downward through the movable ring 53, facilitating the discharge of the debris powder.

[0050] As Figure 7 and Figure 8As shown, a chip outlet 421 is provided on the lower support 42 near the center, which allows the debris and powder inside the guide column 4 to be discharged downwards, preventing the debris and powder from affecting the operation of the reciprocating screw 46. The sealing frame 6 is located below the lower support 42 and is in contact with the inner wall surface of the settling column 3. The upper surface of the sealing frame 6 is an inverted conical surface, which facilitates the discharge of debris and powder. A compression ring 61 is provided on the top of the sealing frame 6 above the lower support 42. The annular seat 62 is welded and fixed to the bottom of the lower support 42. A conical block 622 is provided on the top of the annular seat 62 and on the outer side of the lower support 42. The inner edge of the sealing frame 6 is engaged with the conical block 622. The conical block 622 and the sealing frame 6 cooperate to guide the debris and powder. When the sealing frame 6 and the conical block 622 are engaged, the bottom of the settling column 3 can be sealed, which facilitates the discharge of coolant through the outlet hole 32.

[0051] The inner wall of the annular seat 62 is hollow. The outer wall of the annular seat 62 is provided with strip grooves 621 arranged in annular array. The interior of the annular seat 62 is provided with an annular plate 63 that slides up and down. The outer side of the annular plate 63 is provided with strip blocks 631 arranged in annular array. The strip blocks 631 are slidably connected to the strip grooves 621 and their ends are fixedly connected to the sealing frame 6. A spring 64 is provided inside the annular seat 62 and below the annular plate 63.

[0052] Under the elastic action of spring 64, an upward pressure can be applied to the annular plate 63, causing the sealing frame 6 to engage with the conical block 622, thereby sealing the bottom of the settling column 3. When the pushing ring 5 moves downward and the bottom end of the scraper 51 contacts the extrusion ring 61, a downward pressure can be continuously applied to the extrusion ring 61, causing the extrusion ring 61 to drive the sealing frame 6 downward, thereby separating the sealing frame 6 from the conical block 622, facilitating the downward discharge of debris and powder.

[0053] like Figure 9 As shown, the conveying pipe 7 is located below the settling column 3. The conveying pipe 7 penetrates the side wall of the column 2 and extends to the outside of the column 2. The positioning pipe 71 is located on the side wall of the chip box 14 and is located on the same center line as the conveying pipe 7. The conveying pipe 7 is provided with a connecting bucket 73 connected to the bottom of the settling column 3. The conveying pipe 7 is equipped with a spiral conveying blade 74, which extends to the inside of the positioning pipe 71. The left side of the positioning pipe 71 is equipped with a first motor 741 that is coaxially driven with the spiral conveying blade 74.

[0054] The connecting bucket 73 can collect and guide the debris and powder at the bottom of the settling column 3, so that the debris and powder fall into the inside of the conveying pipe 7. When the first motor 741 runs and drives the spiral conveying blade 74 to rotate, the debris and powder can be continuously conveyed to the left.

[0055] The movable pipe 72 is arranged above the discharging frame 91 and rotatably connected with the conveying pipe 7 and the movable pipe 72 at two ends, the movable pipe 72 is provided with an integrated discharging port 721, the end of the conveying pipe 7 is provided with a locking bolt 722 for fixing the movable pipe 72, the right end of the movable pipe 72 is provided with front and back symmetrical fixing holes, the movable pipe 72 can be fixed through cooperation of the locking bolt 722 and the fixing holes, when the discharging port 721 faces upward, the debris powder can be conveyed into the debris box 14 through the spiral conveying blade 74, so that the various debris can be simultaneously conveyed, when the discharging port 721 faces downward, the debris powder can fall into the discharging frame 91 for discharging, so that the debris powder can be processed separately.

[0056] Working principle: first, the collecting frame 1 collects the debris and cooling liquid generated by the numerical control machine tool processing, the larger debris is filtered through the filter plate 11 and then enters the debris box 14 through the debris discharge port 13, the cooling liquid mixed with the debris powder flows downward through the conveying hopper 12, is guided and diffused by the diffusion cone 47 and the arc-shaped strip 471, uniformly falls on the spiral blade 43, and continuously flows downward along the spiral blade 43, so that the cooling liquid is close to the inner wall of the settling column 3 under the centrifugal action, the settling column 3 magnetically adsorbs the debris powder through the electromagnet 31, separates the debris powder and the cooling liquid, and makes the cooling liquid flow to the waste liquid tank 21 through the liquid outlet hole 32 for recycling;

[0057] Further, the double-output shaft motor 45 drives the reciprocating screw rod 46 to rotate, the lifting block 52 drives the movable ring 53 to move up and down, at the same time, the connecting rod 531 slides along the spiral slide 44, the pushing ring 5 continuously rotates in the moving process, and the debris powder is scraped up by the scraper 51, when the pushing ring 5 moves to the lowest end, the sealing frame 6 is separated from the conical block 622 by the downward extrusion of the extrusion ring 61, then the debris powder falls into the inside of the conveying pipe 7 through the connecting hopper 73, then the spiral conveying blade 74 is driven to rotate by the first motor 741, so that the debris powder can be conveyed, and the separated debris powder is continuously discharged. Embodiment

[0058] This embodiment is an improvement based on embodiment one:

[0059] As Figure 10As shown, during the process of conveying the debris and powder downwards by the temporary separation of the sealing frame 6 and the conical block 622, some of the coolant in the settling column 3 will flow into the interior of the conveying pipe 7. In order to separate the coolant in the conveying pipe 7, the conveying pipe 7 is inclined at an angle of 3°-5° so that the coolant in the conveying pipe 7 can be collected at the bottom right side of the conveying pipe 7. At the same time, an arc-shaped filter frame 75 is also provided on the conveying pipe 7 and below the connecting hopper 73. The arc-shaped filter frame 75 is provided with several evenly distributed micro-filter holes. The coolant can flow downwards through the micro-filter holes and fall into the interior of the waste liquid tank 21.

[0060] Furthermore, to enhance the separation effect of debris and coolant and prevent debris from being mixed in with the coolant flowing into the waste liquid tank 21 through the arc-shaped filter frame 75, an arc-shaped slide 751 is provided inside the arc-shaped filter frame 75. An arc-shaped frame 76 is slidably connected to the inner side of the arc-shaped slide 751. Several evenly distributed filter cloths 761 are installed on the arc-shaped frame 76.

A sealing plate 762 is welded and fixed to the right side of the arc-shaped frame 76. The sealing plate 762 is fixedly connected to the side wall of the column 2 by screws. When the sealing plate 762 is pulled to the right, the arc-shaped frame 76 can slide to the right in the arc-shaped slide 751 and the filter cloths 761 can be separated from the arc-shaped filter frame 75, thereby facilitating the cleaning of the filter cloths 761.

[0061] like Figures 11-13 As shown, to prevent debris from accumulating and clogging the filter plate 11, a pusher mechanism is provided on the collection rack 1 above the filter plate 11. The pusher mechanism includes a vertically parallel sliding plate 8 and a pusher plate 81. Slide grooves 15 are provided on both the front and rear side walls of the collection rack 1.

The slider 82 on the front side of the slide plate 8 is threadedly engaged with the threaded rod 86. The side wall of the collection rack 1 is equipped with a threaded rod 86 that drives the second motor 861 to rotate. When the second motor 861 drives the threaded rod 86 to rotate, the threaded rod 86 and the slider 82 move relative to each other, causing the slider 82 to slide along the slide bar 85, thereby driving the slide plate 8 to move. The slide plate 8 drives the push plate 81 to move, thereby pushing the debris on the filter plate 11 to the left, which facilitates the discharge of debris and avoids the accumulation and blockage of debris.

[0062] The push plate 81 is arranged at the bottom of the sliding plate 8, both ends of the push plate 81 are provided with movable shafts 811 penetrating the sliding blocks 82, the end of the movable shaft 811 is provided with a control plate 812, the center line of the control plate 812 and the center line of the push plate 81 have an included angle of 45°, the control plates 812 on the upper and lower sides are provided with a connecting plate 83, the end of the connecting plate 83 is rotatably connected with the two groups of control plates 812 respectively, the sliding block 82 is provided with an electric push rod 84, the push rod end of the electric push rod 84 is provided with a connecting frame 841, the connecting plate 83 is located at the inner side of the connecting frame 841 and is slidably connected with the connecting frame 841

[0063] When the electric push rod 84 operates to drive the connecting frame 841 to move rightwards, the connecting plate 83 can be driven to move, so that the connecting plate 83 slides in the connecting frame 841 and drives the control plate 812 to rotate by 45°, the push plate 81 is adjusted to the inclined state of 45°, at this time, the edge of the push plate 81 is in contact with the edge of the filter plate 11, when the sliding plate 8 drives the push plate 81 to move leftwards, the debris can be pushed into the chip box 14, when the electric push rod 84 is in the retracted state, the push plate 81 can be adjusted to the horizontal state, at this time, the push plate 81 is kept parallel with the filter plate 11, when the sliding plate 8 drives the push plate 81 to move rightwards, the push plate 81 can avoid driving the debris.

[0064] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the present application, and are not limited to the implementation. For those skilled in the art, on the basis of the above description, other different forms of changes or variations can also be made. Here, it is not necessary and impossible to enumerate all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
