Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, and in particular to a CNC cutting fluid circulation filtering equipment. Background Art

[0002] In mechanical processing, especially CNC (computer numerical control) processing, cutting fluid plays a vital role. It can not only cool the machining tool and workpiece, reduce the cutting temperature and extend the tool life, but also play a lubricating role, reduce cutting force and improve the surface quality of the machining. In order to realize the recycling of cutting fluid, effective filtering of cutting fluid is an essential link.

[0003] During use, cutting fluid will carry a large amount of solid particles such as grinding chips. These solid particles are ejected with the rotation of the cutting fluid. As the filtration proceeds, the grinding chips and other solid impurities will gradually adhere to the surface of the filter cloth, causing the effective filtration area of ​​the filter cloth to gradually decrease, while the resistance of the cutting fluid passing through the filter cloth gradually increases, which will affect the normal filtration. Therefore, in order to maintain the normal operation and filtration effect of the filtration equipment, the filter cloth needs to be cleaned frequently, which not only increases the labor cost, but also directly affects the overall filtration efficiency of the filtration equipment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] An embodiment of a CNC cutting fluid circulation filtering device of the present invention is as follows Figures 1 to 9 shown.

[0029] A CNC cutting fluid circulation and filtering device comprises a frame 100, a shell 200, a liquid separator 210, a filter cloth 300, a push mechanism and a plurality of shields 500. The shell 200 is arranged on the frame 100 along a first direction, the first direction being a vertical direction, and a liquid inlet 201 is provided at the upper end of the shell 200. The liquid separator 210 is installed in the shell 200 and is located below the liquid inlet 201 so as to be rotatable around the first direction. A liquid outlet is provided on the liquid separator 210 so as to catch the falling cutting fluid and throw out the cutting fluid when the liquid separator 210 rotates around the first direction. The filter cloth 300 is arranged in the shell 200 around the first direction and is located between the shell 200 and the liquid separator 210 so as to throw out the cutting fluid onto the filter cloth 300 when the liquid separator 210 rotates around the first direction. A liquid storage cavity 220 is defined between the filter cloth 300 and the housing 200, so that the cutting fluid filtered by the filter cloth 300 can enter the liquid storage cavity 220. A liquid discharge port is provided on the housing 200, and the liquid discharge port is connected to the liquid storage cavity 220 to discharge the filtered cutting fluid.

[0030] The filter cloth 300 is evenly divided into a plurality of pre-filter segments 310 and a plurality of post-filter segments 320 arranged in sequence around a first direction, and the pre-filter segments 310 and the post-filter segments 320 are alternately distributed in sequence around the first direction. The push mechanism is installed in the housing 200, and the action of the push mechanism can cause the pre-filter segment 310 or the post-filter segment 320 to move along the second direction toward the side close to the liquid separation plate 210 and form a bulge, and the second direction is a horizontal direction. A plurality of shields 500 are all arranged in the housing 200, and the shields 500 can cover or leave the pre-filter segment 310, and the plurality of shields 500 are arranged one-to-one with the plurality of pre-filter segments 310.

[0031] The CNC cutting fluid circulation filtering device has a first state and a second state. In the first state, the first filter section 310 forms a bulge relative to the rear filter section 320 along the second direction toward the side close to the liquid separation disk 210, and the shield 500 is now covered on the first filter section 310. In the second state, the rear filter section 320 forms a bulge relative to the first filter section 310 along the second direction toward the side close to the liquid separation disk 210, and the shield 500 leaves the first filter section 310. In the initial state, the CNC cutting fluid circulation filtering device is in the first state.

[0032] This embodiment is provided with a frame 100, a housing 200, a liquid separation plate 210, a filter cloth 300, a push mechanism and a plurality of shields 500. When in use, the cutting fluid is poured into the liquid inlet 201, and the liquid separation plate 210 is driven to rotate around a first direction, the cutting fluid will fall onto the liquid separation plate 210, and the cutting fluid will be thrown out as the liquid separation plate 210 rotates around the first direction.

[0033] At this time, the CNC cutting fluid circulation filtration equipment is in the first state, the first filter section 310 forms a protrusion relative to the rear filter section 320 along the second direction toward the side close to the liquid separation plate 210, and the shield 500 is set on the corresponding first filter section 310, that is, at this time, the filter cloth 300 corresponding to the rear filter section 320 is responsible for filtering the cutting fluid as the main filtering area, and the first filter section 310 does not bear the filtering work for the cutting fluid. Therefore, the cutting fluid thrown out from the liquid separation plate 210 will be filtered by the rear filter section 320, and the filtered cutting fluid will pass through the rear filter section 320 to the liquid storage chamber 220. Solid impurities such as grinding chips in the cutting fluid (hereinafter referred to as impurities) will remain on the rear filter section 320.

[0034] After a period of time, the push mechanism is driven to move the rear filter segment 320 along the second direction to the side close to the liquid separation plate 210 and form a bulge, and the shield 500 leaves the corresponding pre-filter segment 310. Since impurities are already attached to the rear filter segment 320, the pre-filter segment 310 replaces the rear filter segment 320 as the main filtering area to filter the cutting fluid.

[0035] The pushing mechanism is used to successively move the first filter segment 310 and the rear filter segment 320 along the second direction toward the side close to the liquid separation plate 210 and form a protrusion, which can save filtering space and increase the filtering area of ​​the filter cloth 300. During filtering, the first filter segment 310 is first hidden by the shield 500 to keep the first filter segment 310 clean. After impurities are attached to the rear filter segment 320, the first filter segment 310 is used to replace the rear filter segment 320 for filtering, thereby realizing the alternating operation of the first filter segment 310 and the rear filter segment 320. This can not only extend the filtering time and improve the filtering efficiency, but also the first filter segment 310 and the rear filter segment 320 that are alternately distributed around the first direction can separate the impurities on the first filter segment 310 and the impurities on the rear filter segment 320, and divide the impurities into several parts, thereby avoiding the impurities from existing on the filter cloth 300 in the form of a whole block, which is convenient for subsequent cleaning of impurities.

[0036] In this embodiment, a plurality of long ribs 330 are arranged on the filter cloth 300, and the plurality of long ribs 330 are arranged on the filter cloth 300 around the first direction, and the long ribs 330 are elastic. The filter cloth 300 includes an upper half and a lower half, the upper half is cylindrical, and the lower half is conical, the upper half is located at the upper end of the lower half and is fixed to the large end of the lower half. The long ribs 330 are arranged on the upper half and the lower half of the filter cloth 300.

[0037] Furthermore, the upper half of the filter cloth 300 is provided with a plurality of short ribs 340 , the short ribs 340 are elastic, and the plurality of long ribs 330 and the plurality of short ribs 340 are sequentially arranged around the first direction.

[0038] In this embodiment, by providing long ribs 330 and short ribs 340, on the one hand, the filter cloth 300 can be supported by the long ribs 330 and the short ribs 340; on the other hand, when impurities are ejected with the rotation of the liquid separation plate 210, the impact force of the impurities will act on the long ribs 330 and the short ribs 340 at the same time, thereby weakening the impact force on the filter cloth 300.

[0039] In this embodiment, a CNC cutting fluid circulation filtering device further includes a rotating frame 600 and an adjusting frame 700. The rotating frame 600 is coaxially arranged with the housing 200 and can be installed in the housing 200 to rotate around a first direction, and the filter cloth 300 is installed on the rotating frame 600 and can rotate with the rotating frame 600. The filter cloth 300, the adjusting frame 700, and the rotating frame 600 are sequentially arranged in the housing 200 along the second direction, and the filter cloth 300 is located on the side of the rotating frame 600 close to the vertical central axis of the housing 200 in the second direction.

[0040] The pushing mechanism includes multiple hydraulic telescopic rods 400, which are all installed on the adjustment frame 700. In the initial state, each hydraulic telescopic rod 400 abuts against the corresponding pre-filter segment 310, and moves the pre-filter segment 310 along the second direction toward the side close to the liquid separation plate 210 to form a bulge.

[0041] The adjusting frame 700 rotates in coordination with the rotating frame 600. When the CNC cutting fluid circulation filtering device is in the first state, the adjusting frame 700 rotates synchronously with the rotating frame 600 around the first direction; and the adjusting frame 700 rotates relative to the rotating frame 600 and the filter cloth 300 around the first direction so that the rear filter section 320 forms a protrusion relative to the front filter section 310 along the second direction toward the side close to the liquid separation plate 210, that is, the CNC cutting fluid circulation filtering device switches from the first state to the second state.

[0042] Specifically, the adjustment frame 700 has multiple through holes 710 evenly distributed around the first direction to allow filtered cutting fluid to pass through. The rotating frame 600 has multiple through slots around the first direction, and every two adjacent through slots around the first direction are connected by a connecting plate.

[0043] In this embodiment, a rotating column 800 is disposed in the housing 200, the rotating column 800 is disposed along the first direction, and is located on the side of the filter cloth 300 close to the vertical central axis of the housing 200 in the second direction. A first motor 110 is disposed on the frame 100, and the first motor 110 can drive the rotating column 800 to rotate around the first direction. The rotating frame 600 is fixedly connected to the rotating column 800 and can rotate synchronously with the rotating column 800. A second motor 610 is disposed on the rotating frame 600, and the second motor 610 can drive the adjustment frame 700 to rotate around the first direction.

[0044] Specifically, a driving wheel is arranged on the output shaft of the first motor 110, and a rotating wheel is coaxially and fixedly arranged on the rotating column 800. The driving wheel and the rotating wheel are connected by a transmission belt, so that the first motor 110 can drive the rotating column 800 to rotate around the first direction through the transmission belt.

[0045] A driving wheel is arranged on the output shaft of the second motor 610, and a transmission ring is arranged on the adjusting frame 700. The driving wheel is meshed with the transmission ring so that the driving wheel can drive the transmission ring to rotate, thereby driving the adjusting frame 700 to rotate. The driving wheel is a friction wheel, and the outer peripheral wall surface of the transmission ring is a friction surface, or the driving wheel is a gear, and the transmission ring is a gear ring.

[0046] Further, the upper end of the shield 500 is mounted on the rotating frame 600 through the third motor 620, and the third motor 620 can drive the upper end of the shield 500 to rotate around the first reference axis, and the first reference axis is perpendicular to the vertical center axis of the shield 500. The third motor 620 is electrically connected to the second motor 610, so that when the second motor 610 is started, the third motor 620 can be started.

[0047] Specifically, a rotating column 800 is provided on the baffle cover 500, and the rotating column 800 rotates in coordination with the rotating frame 600. A driving wheel is provided at the output end of the third motor 620, and a mating wheel is provided on the rotating column 800. The driving wheel meshes with the mating wheel. When the third motor 620 is started, the driving wheel can drive the mating wheel to rotate around the first reference axis, and drive the rotating column 800 to rotate through the mating wheel. The rotation of the rotating column 800 will drive the baffle cover 500 to rotate, and the first reference axis is the axis of the rotating column 800.

[0048] In the initial state, the first motor 110 is started and the second motor 610 is stopped. The first motor 110 is started to drive the rotating column 800 to rotate, and the rotating frame 600 is driven to rotate through the rotating column 800. The rotation of the rotating frame 600 will drive the second motor 610 to rotate, and the driving wheel on the second motor 610 drives the transmission ring to rotate synchronously, so that the adjustment frame 700 can rotate synchronously, and the rotating frame 600 will also drive the filter cloth 300 to rotate synchronously. That is, the rotating frame 600, the adjustment frame 700 and the filter cloth 300 rotate synchronously. When the cutting fluid is thrown out from the liquid separation plate 210 and falls on the first filter section 310, by making the rotating frame 600, the adjustment frame 700 and the filter cloth 300 rotate synchronously, the range in which the filter cloth 300 can receive the cutting fluid is increased, and the cutting fluid is prevented from falling on only part of the filter cloth 300.

[0049] When the CNC cutting fluid circulation filter device needs to be switched from the first state to the second state, the multiple hydraulic telescopic rods 400 are first retracted in the second direction, and then the second motor 610 is started to rotate the adjustment frame 700 relative to the rotating frame 600 around the first direction, and the first motor 110 is temporarily stopped. The rotation of the adjustment frame 700 will drive the hydraulic telescopic rods 400 arranged thereon to rotate, thereby rotating the hydraulic telescopic rods 400 from the first filter section 310 to the rear filter section 320, and after the rotation, the hydraulic telescopic rods 400 are extended in the second direction, thereby forming a bulge on the side of the rear filter section 320 relative to the first filter section 310 along the second direction close to the liquid separation plate 210.

[0050] In this embodiment, an adjusting column 900 is provided in the outer shell 200. The adjusting column 900 is coaxially arranged with the rotating column 800 and is located between the rotating column 800 and the filter cloth 300. The rotating column 800 is hollow inside, and a driving member is provided in the rotating column 800. The driving member can drive the adjusting column 900 to move up and down, and the lower end of the filter cloth 300 is fixedly mounted on the adjusting column 900.

[0051] Further, the driving member is a hydraulic telescopic cylinder, and an adjusting rod 810 is provided at the output end of the hydraulic telescopic cylinder. The adjusting rod 810 can be installed on the output end of the hydraulic telescopic cylinder so as to rotate around a first direction, and can move synchronously with the output end of the hydraulic telescopic cylinder. The adjusting column 900 is fixedly connected to the adjusting rod 810, and a spline is provided on the outer peripheral wall surface of the rotating column 800, and the spline is arranged along the first direction. A keyway is provided on the inner peripheral wall surface of the adjusting column 900, and the keyway and the spline are slidably matched in the initial state. The adjusting rod 810 has a spiral section, and when the adjusting column 900 moves downward to disengage the spline on the rotating column 800 from the keyway on the adjusting column 900, the rotating column 800 can spirally match with the spiral section on the adjusting rod 810.

[0052] Furthermore, a material drop opening is provided at the lower end of the rotating frame 600, and a collecting bucket 120 is provided on the frame 100, and the collecting bucket 120 is located at the lower end of the material drop opening. By providing the collecting bucket 120, impurities falling from the filter cloth 300 can fall onto the collecting bucket 120 through the material drop opening, so that the impurities can be collected conveniently.

[0053] In this embodiment, an adjusting column 900 is provided and fixedly connected to the adjusting rod 810. When the filter cloth 300 needs to be cleaned, the adjusting rod 810 can be driven downward by the hydraulic telescopic cylinder, and the adjusting column 900 can be driven downward by the adjusting rod 810. Since the upper end of the filter cloth 300 is fixedly connected to the rotating frame 600 and the lower end is fixedly connected to the adjusting column 900, the lower end of the filter cloth 300 will move downward relative to the upper end of the filter cloth 300, so that the filter cloth 300 is extended.

[0054] By setting a spiral section on the adjusting rod 810, the keyway and the spline are slidably matched in the initial state, and then when the first motor 110 starts to drive the rotating column 800 to rotate, the rotating column 800 can drive the adjusting column 900 to rotate, and drive the lower end of the filter cloth 300 to rotate through the adjusting column 900, and at the same time, the rotating column 800 will also drive the rotating frame 600 to rotate, and drive the upper end of the filter cloth 300 to rotate through the rotating frame 600, that is, when the first motor 110 is started, the rotating column 800, the adjusting column 900, the rotating frame 600, the filter cloth 300, and the adjusting frame all rotate synchronously. At this time, the second motor 610 stops.

[0055] When the hydraulic telescopic cylinder drives the adjusting rod 810 to move downward, and then drives the adjusting column 900 to move downward, when the adjusting column 900 moves downward until the spline on the rotating column 800 is disengaged from the keyway on the adjusting column 900, the rotating column 800 can be spirally matched with the spiral section on the adjusting rod 810, that is, the adjusting rod 810 rotates around the first direction relative to the rotating column 800. The rotation of the adjusting rod 810 will drive the adjusting column 900 fixed thereto to rotate synchronously, and then drive the lower end of the filter cloth 300 to rotate around the first direction through the adjusting column 900, twisting the filter cloth 300 to a certain extent, and assisting the impurities on the filter cloth 300 to fall off, and due to the arrangement of the long ribs 330 and the short ribs 340, when the lower end of the filter cloth 300 is twisted and stretched, it can play a buffering role in the stretching of the filter cloth 300, avoiding excessive stretching of the filter cloth 300, and playing a certain protective role for the filter cloth 300.

[0056] The adjusting rod 810 is then driven upward by the hydraulic telescopic cylinder, thereby driving the adjusting column 900 to move upward. During this process, the spiral section on the adjusting rod 810 cooperates with the spiral of the rotating column 800, thereby causing the adjusting rod 810 to reverse and reset, and driving the adjusting column 900 to reverse synchronously, so that the filter cloth 300 is reversely twisted and reset. At this time, the spline on the rotating column 800 cooperates with the keyway on the adjusting column 900 again, and the lower end of the filter cloth 300 is moved upward relative to the upper end of the filter cloth 300 through the adjusting column 900 to reset the filter cloth 300. The filter cloth 300 is stretched reciprocally in this way, so that the impurities on the filter cloth 300 can be shaken off, and the impurities falling from the filter cloth 300 can fall into the collecting bucket 120 through the dropping port, so as to facilitate the collection of the impurities.

[0057] In this embodiment, a main motor 230 is disposed on the housing 200 , the output shaft of the main motor 230 is tilted, and the liquid separation plate 210 is mounted on the output shaft of the main motor 230 .

[0058] By tilting the main motor 230, the separator plate 210 is tilted in the housing 200. When the main motor 230 rotates and drives the separator plate 210 to rotate to throw out the cutting fluid, the tilted separator plate 210 increases the range in which the filter cloth 300 can receive the cutting fluid.

[0059] In combination with the above embodiments, the specific working process is as follows:

[0060] When in use, the cutting fluid is poured in from the liquid inlet 201, and the main motor 230 is started to drive the liquid separation plate 210 to rotate around the first direction. The cutting fluid will fall onto the liquid separation plate 210 and be thrown out as the liquid separation plate 210 rotates around the first direction.

[0061] At this time, the CNC cutting fluid circulation filtering device is in the first state, the first filter section 310 forms a protrusion relative to the rear filter section 320 along the second direction toward the side close to the liquid separation plate 210, and the shield 500 is set on the corresponding first filter section 310, that is, at this time, the filter cloth 300 corresponding to the rear filter section 320 is the main filtering area to bear the filtering work for the cutting fluid, and the first filter section 310 does not bear the filtering work for the cutting fluid. Therefore, the cutting fluid thrown out from the liquid separation plate 210 will be filtered by the rear filter section 320.

[0062] At the same time, the first motor 110 is started, and the second motor 610 is stopped. The first motor 110 is started to drive the rotating column 800 to rotate, and the rotating frame 600 is driven to rotate through the rotating column 800. The rotation of the rotating frame 600 will drive the second motor 610 to rotate, and the driving wheel on the second motor 610 drives the transmission ring to rotate synchronously, so that the adjustment frame 700 can rotate synchronously, and the rotating frame 600 will also drive the filter cloth 300 to rotate synchronously. That is, the rotating frame 600, the adjustment frame 700 and the filter cloth 300 rotate synchronously. When the cutting fluid is thrown out from the liquid separation plate 210 and falls on the first filter section 310, by making the rotating frame 600, the adjustment frame 700 and the filter cloth 300 rotate synchronously, the range in which the filter cloth 300 can receive the cutting fluid is increased, and the cutting fluid is prevented from falling on only part of the filter cloth 300.

[0063] The filtered cutting fluid will pass through the rear filter section 320 to the liquid storage chamber 220 . Solid impurities such as grinding chips (hereinafter referred to as impurities) in the cutting fluid will remain on the rear filter section 320 .

[0064] After a period of time, when the CNC cutting fluid circulation filtration device needs to be switched from the first state to the second state, the multiple hydraulic telescopic rods 400 are first retracted in the second direction, and then the second motor 610 is started to rotate the adjustment frame 700 relative to the rotating frame 600 around the first direction, and the first motor 110 is temporarily stopped. The rotation of the adjustment frame 700 will drive the hydraulic telescopic rods 400 set thereon to rotate, thereby rotating the hydraulic telescopic rods 400 from the first filter section 310 to the rear filter section 320, and after the rotation, the hydraulic telescopic rods 400 are extended in the second direction, thereby forming a bulge on the side of the rear filter section 320 relative to the first filter section 310 along the second direction close to the liquid separation plate 210. Since impurities are already attached to the rear filter section 320, that is, at this time, the first filter section 310 replaces the rear filter section 320 as the main filtering area to undertake the filtering work for the cutting fluid.

[0065] When the filter cloth 300 needs to be cleaned, the adjusting rod 810 can be driven downward by the hydraulic telescopic cylinder, and the adjusting column 900 can be driven downward by the adjusting rod 810. Since the upper end of the filter cloth 300 is fixed to the rotating frame 600 and the lower end is fixed to the adjusting column 900, the lower end of the filter cloth 300 will move downward relative to the upper end of the filter cloth 300, so that the filter cloth 300 is extended.

[0066] When the hydraulic telescopic cylinder drives the adjustment rod 810 to move downward, and then drives the adjustment column 900 to move downward, when the adjustment column 900 moves downward until the spline on the rotating column 800 is disengaged from the keyway on the adjustment column 900, the rotating column 800 can be spirally matched with the spiral section on the adjustment rod 810, that is, the adjustment rod 810 rotates around the first direction relative to the rotating column 800. The rotation of the adjustment rod 810 will drive the adjustment column 900 fixed thereto to rotate synchronously, and then drive the lower end of the filter cloth 300 to rotate around the first direction through the adjustment column 900, twist the filter cloth 300 to a certain extent, and assist in the removal of impurities on the filter cloth 300.

[0067] The adjusting rod 810 is then driven upward by the hydraulic telescopic cylinder, thereby driving the adjusting column 900 to move upward. During this process, the spiral section on the adjusting rod 810 cooperates with the spiral of the rotating column 800, thereby causing the adjusting rod 810 to reverse and reset, and driving the adjusting column 900 to reverse synchronously, so that the filter cloth 300 is reversely twisted and reset. At this time, the spline on the rotating column 800 cooperates with the keyway on the adjusting column 900 again, and the lower end of the filter cloth 300 is moved upward relative to the upper end of the filter cloth 300 through the adjusting column 900 to reset the filter cloth 300. The filter cloth 300 is stretched reciprocally in this way, so that the impurities on the filter cloth 300 can be shaken off, and the impurities falling from the filter cloth 300 can fall into the collecting bucket 120 through the dropping port, so as to facilitate the collection of the impurities.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
