DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various forms, so the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not connected with the invention will be omitted from the drawings. The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example

[0023] This embodiment introduces a specific structure of a chip removal device for a CNC machine tool. Figure 1-Figure 13As shown, it includes a collecting frame 1, and two groups of upper and lower parallel filter plates 11 are arranged inside the collecting frame 1, a conveying bucket 12 is arranged at the bottom of the collecting frame 1, a column 2 is arranged below the collecting frame 1, a sedimentation column 3 is arranged inside the column 2, the top of the sedimentation column 3 is connected to the conveying bucket 12, a magnetic attraction mechanism is arranged on the outside of the sedimentation column 3 and near the top, a guide column 4 is arranged at the inner center of the sedimentation column 3, a pushing mechanism is arranged on the outside of the guide column 4, the pushing mechanism includes a pushing ring 5, a lifting block 52 and a movable ring 53, a driving mechanism for driving the pushing ring 5 to move is arranged on the guide column 4, a sealing mechanism for blocking the waste liquid is arranged at the bottom of the sedimentation column 3, the sealing mechanism includes a sealing frame 6 and an annular seat 62, a conveying mechanism is arranged below the sedimentation column 3, the conveying mechanism includes a conveying pipe 7, a positioning pipe 71 and a movable pipe 72.

[0024] A chip discharge port 13 is provided on the left side wall of the collecting rack 1 and near the filter plate 11, and an inclined chip discharge box 14 is provided on the left side of the collecting rack 1. The bottom of the chip discharge box 14 is connected to a conveying rack 9, and a discharging rack 91 is welded and fixed to the right side of the conveying rack 9. A conveyor belt 92 is installed inside the conveying rack 9, and a third motor 921 for driving the conveyor belt 92 is installed on the front side of the conveying rack 9. A waste liquid tank 21 is welded and fixed to the bottom of the column 2, and a magnetic suction chamber 22 and a collecting chamber 23 are provided inside the column 2. The collecting chamber 23 is arranged below the magnetic suction chamber 22 and is connected to the waste liquid tank 21. A recovery pipe 211 is provided on the right side of the waste liquid tank 21, and the bottom end of the recovery pipe 211 passes through the side wall of the waste liquid tank 21 and extends to the interior of the waste liquid tank 21, and a pump body 212 is installed at the bottom of the recovery pipe 211 and on the inner side of the waste liquid tank 21.

[0025] When in use, the collecting rack 1 collects the chips and coolant generated by the CNC machine tool, and performs preliminary filtering through the two sets of filter plates 11 arranged inside the collecting rack 1. The larger chips are filtered by the filter plates 11 and discharged to the inside of the chip box 14 through the chip discharge port 13. Then, they fall onto the conveyor belt 92 through the chip box 14 and are discharged to the outside. The coolant mixed with the chip powder falls into the sedimentation column 3 through the conveying bucket 12 and flows downward in the sedimentation column 3. At the same time, the magnetic suction mechanism operates to make the sedimentation column 3 filter the coolant. The debris powder is magnetically adsorbed and attached to the inner wall of the sedimentation column 3. The coolant flows to the bottom end of the sedimentation column 3, and after being blocked by the sealing mechanism, it flows to the collecting chamber 23 through the liquid outlet 32 ​​on the sedimentation column 3, and then flows to the inside of the waste liquid tank 21 through the collecting chamber 23 for recovery. The pushing ring 5 is driven back and forth by the driving mechanism, so that the pushing ring 5 pushes the debris attached to the sedimentation column 3 to the bottom end, and squeezes the sealing frame 6 downward, so that the debris falls into the inside of the conveying pipe 7, and then can be discharged outward through the conveying pipe 7.

[0026] like Figure 4-Figure 6As shown, the magnetic attraction mechanism is arranged on the inner side of the magnetic attraction cavity 22, and the magnetic attraction mechanism includes a plurality of evenly distributed electromagnets 31, and the electromagnets 31 are installed on the outer wall surface of the sedimentation column 3. A shield 311 is installed on the outer wall of the sedimentation column 3 and located on the outer side of the electromagnet 31, and the shield 311 protects the electromagnet 31. A plurality of evenly distributed liquid outlet holes 32 are opened on the side wall of the sedimentation column 3 and located on the inner side of the collecting cavity 23, and a connecting ring 33 is welded and fixed to the bottom of the sedimentation column 3.

[0027] The sedimentation column 3 is made of a metal material with good magnetic conductivity. When the electromagnet 31 is running, the sedimentation column 3 can generate magnetism and magnetically adsorb the debris powder inside the sedimentation column 3, so that the debris powder adheres to the inner wall surface of the sedimentation column 3, thereby separating the debris powder from the coolant.

[0028] An upper bracket 41 is provided at the top of the guide column 4, and a lower bracket 42 is provided at the bottom of the guide column 4. The upper bracket 41 and the lower bracket 42 are both welded and fixed to the inner wall of the sedimentation column 3. A spiral blade 43 is provided on the outer side of the guide column 4. The upper and lower ends of the spiral blade 43 are respectively welded and fixed to the upper bracket 41 and the lower bracket 42, and there is a gap between the inner circle edge of the spiral blade 43 and the outer wall surface of the guide column 4, and between the outer circle edge of the spiral blade 43 and the inner wall surface bracket of the sedimentation column 3. A spiral slide 44 is opened on the side wall of the guide column 4.

[0029] After the coolant falls into the interior of the sedimentation column 3, the coolant can flow downward along the spiral blade 43, and under the action of centrifugal force, the coolant and the debris powder gradually approach the inner wall edge of the sedimentation column 3, thereby improving the magnetic adsorption efficiency of the debris powder and the discharge efficiency of the coolant. Since there are gaps between the inner and outer ring edges of the spiral blade 43, the gap between the inner ring edge of the spiral blade 43 and the outer surface of the guide column 4 can generate convection air at the inner ring of the spiral blade 43, which is convenient for blowing up some of the debris powder. The gap between the outer ring edge of the spiral blade 43 and the inner surface of the sedimentation column 3 facilitates the push ring 5 to move up and down, and pushes the debris powder attached to the inner surface of the sedimentation column 3.

[0030] The driving mechanism includes 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 bracket 41. A protective shell 451 is installed on the upper bracket 41 and located on the outside of the double-output shaft motor 45. The reciprocating screw rod 46 is arranged below the upper bracket 41 and is coaxially driven with the lower output shaft of the double-output shaft motor 45. A diffusion cone 47 is provided above the double-output shaft motor 45. The diffusion cone 47 is coaxially driven with the upper output shaft of the double-output shaft motor 45, and arc strips 471 distributed in a circular array are provided on the conical surface of the diffusion cone 47.

[0031] When the double-output shaft motor 45 is running, it can drive the reciprocating screw 46 and the diffusion cone 47 to rotate simultaneously. When the diffusion cone 47 rotates, it cooperates with the arc strip 471 to guide the coolant falling into the inner side of the sedimentation column 3, so that the coolant is evenly diffused around, making it convenient for the coolant to fall on the spiral blade 43 and flow.

[0032] The outer surface of the push ring 5 contacts the inner wall surface of the sedimentation column 3. The bottom of the push ring 5 is provided with a scraper 51 distributed in a circular array. The push ring 5 and the scraper 51 are both made of non-magnetic alloy material that does not have magnetic conductivity, so that the push ring 5 and the scraper 51 do not generate magnetic induction under the action of the magnetic field, which is convenient for pushing the debris powder attached to the sedimentation column 3. The lifting block 52 is slidably arranged on the outside of the reciprocating screw 46 and is slidably connected to the guide column 4. Limit blocks 521 are provided at the upper and lower ends of the lifting block 52. A limit groove corresponding to the limit block 521 is provided on the inner wall of the guide column 4. The limit block 521 slides up and down along the limit groove, which can limit the lifting block 52 and prevent the reciprocating screw 46 from driving the lifting block 52 to rotate, thereby ensuring that the lifting block 52 reciprocates up and down on the guide column 4.

[0033] The movable ring 53 is arranged on the lifting block 52 and is rotatably connected to the lifting block 52. A spirally evenly distributed connecting rod 531 is welded and fixed to the outer side of the movable ring 53. The connecting rod 531 is slidably connected to the spiral slide 44, and the end of the connecting rod 531 is welded and fixed to the inner wall of the push ring 5. The spiral slide 44 is located in the middle position of the adjacent tangent points of the spiral blade 43, so that the upper and lower surfaces of the connecting rod 531 and the spiral blade 43 have a large spacing.

[0034] When the double-output shaft motor 45 drives the reciprocating screw 46 to operate, the transmission is carried out through the reciprocating screw 46, and under the limiting action of the limit block 521, the lifting block 52 drives the movable ring 53 to move downward. At the same time, the connecting rod 531 slides along the spiral slide 44, so that the movable ring 53 drives the push ring 5 to rotate during the downward movement, and the push ring 5 drives the scraper 51 to rotate, so that the scraper 51 scrapes up the debris powder attached to the inner wall surface of the sedimentation column 3, and continues to push downward through the movable ring 53, so as to facilitate the discharge of the debris powder.

[0035] like Figure 7 and Figure 8As shown, a chip outlet 421 is provided on the lower bracket 42 near the center, so that the debris powder inside the guide column 4 can be discharged downward to prevent the debris powder from affecting the operation of the reciprocating screw rod 46. The sealing frame 6 is arranged below the lower bracket 42 and fits with the inner wall surface of the sedimentation column 3. The upper surface of the sealing frame 6 is an inverted cone, which is convenient for discharging the debris powder. An extrusion ring 61 is provided on the top of the sealing frame 6 and located above the lower bracket 42. The annular seat 62 is welded and fixed to the bottom of the lower bracket 42. A conical block 622 is provided on the top of the annular seat 62 and located on the outside of the lower bracket 42. The inner ring edge of the sealing frame 6 is snap-fitted with the conical block 622. The conical block 622 cooperates with the sealing frame 6 to guide the debris powder. When the sealing frame 6 is snap-fitted with the conical block 622, the bottom of the sedimentation column 3 can be closed, which facilitates the discharge of the coolant through the liquid outlet 32.

[0036] The inner wall of the annular seat 62 is a hollow structure, and the outer wall of the annular seat 62 is provided with strip grooves 621 distributed in an annular array. The inside of the annular seat 62 is provided with an annular plate 63 that slides up and down, and the inner side of the annular plate 63 is provided with strip blocks 631 distributed in an annular array. The strip blocks 631 are slidably connected to the strip grooves 621, and the 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.

[0037] Under the elastic action of the spring 64, upward pressure can be applied to the annular plate 63, so that the sealing frame 6 and the conical block 622 are engaged with each other, thereby closing the bottom of the sedimentation column 3. When the push ring 5 moves downward and the bottom end of the scraper 51 contacts the extrusion ring 61, downward pressure can be continuously applied to the extrusion ring 61, so that the extrusion ring 61 drives the sealing frame 6 to move downward, thereby separating the sealing frame 6 from the conical block 622, facilitating the downward discharge of debris and powder.

[0038] like Fig. 9 As shown, the conveying pipe 7 is arranged below the sedimentation column 3, the conveying pipe 7 passes through the side wall of the column 2 and extends to the outside of the column 2, the positioning pipe 71 is arranged on the side wall of the chip removal box 14 and is located on the same center line as the conveying pipe 7, and a connecting bucket 73 connected to the bottom of the sedimentation column 3 is arranged on the conveying pipe 7, a spiral conveying blade 74 is installed inside the conveying pipe 7, and the spiral conveying blade 74 extends to the inner side of the positioning pipe 71, and a first motor 741 coaxially driven with the spiral conveying blade 74 is installed on the left side of the positioning pipe 71.

[0039] The connecting bucket 73 can collect and guide the debris powder at the bottom end of the sedimentation column 3, so that the debris powder falls into the interior of the conveying pipe 7. When the first motor 741 drives the spiral conveying blade 74 to rotate, the debris powder can be continuously conveyed to the left.

[0040] The movable tube 72 is arranged above the discharge rack 91, and the two ends are rotatably connected to the conveying tube 7 and the movable tube 72 respectively. The movable tube 72 is provided with an integrally formed discharge port 721, and the end of the conveying tube 7 is provided with a locking bolt 722 for fixing the movable tube 72. The right end of the movable tube 72 is provided with front and rear symmetrical fixing holes, and the movable tube 72 can be fixed by matching the locking bolts 722 with the fixing holes. When the discharge port 721 is facing upward, the debris powder can be conveyed to the chip discharge box 14 through the spiral conveying blades 74, thereby conveying multiple debris at the same time. When the discharge port 721 is facing downward, the debris powder can fall into the discharge rack 91 for discharge, thereby processing the debris powder separately.

[0041] Working principle: First, the collecting rack 1 collects the chips and coolant generated by the CNC machine tool processing, and after filtering through the filter plate 11, the larger chips are discharged into the chip box 14 through the chip discharge port 13, and the coolant mixed with the chip powder flows downward through the conveying bucket 12, and after being guided and diffused by the diffusion cone 47 and the arc strip 471, it evenly falls on the spiral blade 43 and continues to flow downward along the spiral blade 43, so that the coolant approaches the inner wall of the sedimentation column 3 under the action of centrifugation, and the sedimentation column 3 is magnetically adsorbed on the chip powder by the electromagnet 31, so that the chip powder and the coolant are separated, and the coolant flows to the waste liquid tank 21 through the liquid outlet 32 ​​for recovery; Furthermore, the double-output shaft motor 45 drives the reciprocating screw rod 46 to rotate, so that the lifting block 52 drives the movable ring 53 to move up and down reciprocatingly. At the same time, the connecting rod 531 slides along the spiral slide 44, so that the push ring 5 rotates continuously during the movement, and the debris powder is scraped up by the scraper 51. When the push ring 5 moves to the lowest end, the scraper 51 squeezes the extrusion ring 61 downward to separate the sealing frame 6 from the conical block 622. After that, the debris powder falls into the interior of the conveying pipe 7 through the connecting bucket 73. After that, the spiral conveying blade 74 is driven to rotate by the first motor 741 to convey the debris powder, thereby continuously discharging the separated debris powder. Example

[0042] This embodiment is an improvement based on the first embodiment: like Fig.10 As shown, due to the brief separation of the sealing frame 6 and the conical block 622 to transport the debris powder downward, part of the coolant in the sedimentation column 3 will flow to the inside 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 gathered at the right bottom end of the conveying pipe 7. At the same time, an arc filter frame 75 is provided on the conveying pipe 7 and below the connecting bucket 73. The arc filter frame 75 is provided with a plurality of evenly distributed micro filter holes. The coolant can flow downward through the micro filter holes and fall into the inside of the waste liquid tank 21.

[0043] Furthermore, in order to enhance the separation effect of debris powder and coolant and prevent the coolant flowing into the waste liquid tank 21 through the arc filter frame 75 from being mixed with debris powder, an arc filter frame 75 is provided with an arc slide 751 inside, and an arc frame 76 is slidably connected to the inner side of the arc slide 751, and a plurality of evenly distributed filter cloths 761 are installed on the arc frame 76. The debris powder can be further filtered and separated inside the arc filter frame 75 through the filter cloth 761, thereby improving the filtering effect of the arc filter frame 75. A sealing plate 762 is welded and fixed on the right side of the arc frame 76, and 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 frame 76 can slide to the right in the arc slide 751, and the filter cloth 761 can be separated from the arc filter frame 75, thereby facilitating the cleaning of the filter cloth 761.

[0044] like Figure 11-13 As shown, in order to prevent debris from accumulating and clogging on the filter plate 11, a push plate mechanism is provided on the collection rack 1 and above the filter plate 11. The push plate mechanism includes a slide plate 8 and a push plate 81 which are parallel to each other. A slide groove 15 is provided on the front and rear side walls of the collection rack 1. The end of the slide plate 8 is slidably connected to the slide groove 15. Slide blocks 82 are provided at both ends of the slide plate 8 and on the outside of the collection rack 1. A protective frame 821 is provided at the edge of the slide block 82. A slide bar 85 is installed on the rear side of the collection rack 1. The slide block 82 on the rear side of the slide block 8 slides with the slide bar 85. A threaded rod 86 is installed on the front side of the collecting rack 1, and a slider 82 on the front side of the slide 8 is threadedly matched with the threaded rod 86. A threaded rod 86 for driving the second motor 861 to rotate is installed on the side wall of the collecting rack 1. 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, so that the slider 82 slides along the slide rod 85, thereby driving the slide 8 to move, and the slide 8 drives the push plate 81 to move, thereby pushing the debris on the filter plate 11 to the left, facilitating the discharge of the debris and avoiding debris accumulation and blockage.

[0045] The push plate 81 is arranged at the bottom of the slide plate 8, and both ends of the push plate 81 are provided with a movable shaft 811 penetrating the slider 82, and the end of the movable shaft 811 is provided with a control plate 812, and the center line of the control plate 812 and the center line of the push plate 81 have an angle of 45 degrees, and a connecting plate 83 is provided between the control plates 812 on the upper and lower sides, and the ends of the connecting plate 83 are respectively connected to the two groups of control plates 812 for rotation, and an electric push rod 84 is installed on the slider 82, and a connecting frame 841 is installed at the push rod end of the electric push rod 84, and the connecting plate 83 is located on the inner side of the connecting frame 841 and is slidably connected to the connecting frame 841. When the electric push rod 84 drives the connecting frame 841 to move to the right, it can drive the connecting plate 83 to move, so that the connecting plate 83 slides in the connecting frame 841, and drives the control plate 812 to rotate 45°, and adjust the push plate 81 to a 45° inclined state. At this time, the edge of the push plate 81 contacts the edge of the filter plate 11. When the slide plate 8 drives the push plate 81 to move to the left, the debris can be pushed to the left into the chip box 14. When the electric push rod 84 is in a retracted state, the push plate 81 can be adjusted to a horizontal state. At this time, the push plate 81 and the filter plate 11 remain parallel. When the slide plate 8 drives the push plate 81 to move to the right, the push plate 81 can be prevented from driving the debris.
