Description

Technical Field

[0001] The invention relates to a mechanical device, in particular to a groove cutting device. Background Art

[0002] In the field of mechanical equipment, metal cutting machine tools for engine processing all use cutting fluids for tool cooling and lubrication. Cylinder blocks, cylinder heads, and connecting rods use emulsions, whose main chemical components are water, mineral oil, synthetic esters, surfactants, rust inhibitors, and extreme pressure additives.

[0003] However, as the use time increases, the cutting fluid will gradually deteriorate and become ineffective. The specific manifestations are as follows:

[0004] (1) Fine metal cutting particles and increased oxide scale debris in the blank. Fine metal particles are poured onto the cutting edge of the tool tip along with the cutting fluid, causing the tool edge to be ground, accelerating tool wear and shortening tool life.

[0005] (2) The mineral salt components brought into the blank will increase the chloride ions in the cutting fluid, causing the cutting fluid to "break the emulsion", that is, the oil and water stratification, making the cutting ineffective.

[0006] (3) The accumulation of fine metal particles in the cutting oil can easily produce bacteria to form colloids, making the cutting fluid stink.

[0007] Therefore, the existing cutting fluid has a short lifespan, and using an ineffective cutting fluid will affect the operation and use of the equipment. Replacing the cutting fluid will lead to the following problems:

[0008] (1) It causes industrial wastewater discharge, which is not conducive to environmental protection;

[0009] (2) There are several hundred cubic meters of cutting fluid in the entire cutting fluid tank, and the cost of cutting fluid is relatively high;

[0010] (3) Each time the fluid is changed, water and cutting fluid must be mixed and stirred evenly in proportion. If the concentration is not configured or the mixing is uneven, the viscosity characteristics of the cutting fluid will change, and an oil film cannot be formed on some tool guides, resulting in quality problems in the processed parts.

[0011] Therefore, it is desirable to provide a cutting fluid regeneration device with a self-cleaning function, which can regenerate and update the cutting fluid online during use. Summary of the invention

[0012] The object of the present invention is to provide a cutting fluid regeneration device with a self-cleaning function, which can regenerate and update the cutting fluid online during use, thereby maintaining the normal operation of the device while ensuring that the production efficiency is not reduced.

[0013] In order to achieve the above object, the present invention proposes a cutting fluid regeneration device with a self-cleaning function, which includes a cylindrical cutting fluid tank, and further includes:

[0014] A plurality of compressed air pipes are connected to a compressed air source, the plurality of compressed air pipes are distributed along the circumferential direction of the cutting fluid tank, and the blowing holes at the tail ends of the compressed air pipes are at different heights in the height direction of the cutting fluid tank, and the blowing direction of each of the blowing holes is tangent to the radial direction of the cutting fluid tank;

[0015] An annular track, which is arranged on the periphery of the cutting fluid tank;

[0016] A curved plate slide groove, the lower end of which is slidably connected to the annular track, and the curved plate slide groove extends along the outer wall of the cutting fluid groove in the height direction thereof;

[0017] A magnetic head is used to absorb cutting particles in the cutting fluid tank, and the magnetic head can slide along the curved plate slide groove to transport the cutting particles from the bottom of the cutting fluid tank to the upper part of the cutting tank, and the upper part of the cutting tank is provided with a sewage outlet for discharging the cutting particles;

[0018] The magnetic head driving assembly drives the curved plate slide groove to slide along the annular track, and drives the magnetic head to slide along the curved plate slide groove;

[0019] A waste liquid bucket, which is movably arranged in the cutting liquid tank;

[0020] A cathode electrode and an anode electrode are fixedly arranged relative to the waste liquid bucket and arranged above it;

[0021] A waste liquid bucket driving assembly drives the waste liquid bucket, the cathode electrode and the anode electrode to move in the height direction of the cutting liquid tank;

[0022] Among them, when the cathode electrode and the anode electrode are immersed in the cutting fluid in the cutting fluid tank, they absorb the charged substances in the cutting fluid; when the cathode electrode, the anode electrode and the waste liquid bucket leave the cutting fluid driven by the waste liquid bucket driving assembly, the cathode electrode and the anode electrode are short-circuited to allow the charged substances to fall into the waste liquid tank below.

[0023] The cutting fluid regeneration device with self-cleaning function of the present invention utilizes the blowing of compressed air to form a vortex in the cutting groove.

[0024] At the same time, when the cutting fluid flows in the space formed by the cathode and anode electrodes, under the action of the electric field force, the chloride ions, charged colloidal particles, charged organic matter and bacteria in the cutting fluid will migrate to the electrodes with opposite charges respectively, be adsorbed by the electrodes and stored on the electrode surface, so that the chloride ions in the cutting fluid are enriched and concentrated on the electrode surface, thereby achieving the purpose of regenerating the cutting fluid.

[0025] Among them, when the waste liquid bucket, cathode electrode, and anode electrode rise and separate from the cutting fluid in the cutting fluid tank, the cathode electrode and the anode electrode are short-circuited to each other, so that the electrodes lose their adsorption force on positive and negative charges. In this way, the charged substances on the surface of the electrode fall into the cutting fluid in the waste liquid bucket, forming a cutting waste fluid that enriches the chloride ions and metal ions in the cutting fluid into a high ion concentration.

[0026] In addition, the present invention energizes the coil in the magnetic head to generate a magnetic field to absorb the fine metal cutting particles deposited on the bottom and outer wall of the cutting groove. The magnetic head spirals up along the outer wall of the cutting groove to achieve the purpose of absorbing the metal debris particles at the bottom of the cutting fluid groove and transporting them to the drain outlet of the cutting fluid groove for discharge.

[0078] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the cutting fluid regeneration device with self-cleaning function of the present invention comprises a cylindrical cutting fluid tank 27, in which cutting fluid is filled. The cutting fluid regeneration device with self-cleaning function realizes the regeneration of cutting fluid through the joint action of the compressed air pipe 7, the magnetic head 19, the cathode electrode 9 and the anode electrode 10.

[0079] Figure 5 The figure shows the setting state of the compressed air pipe of the cutting fluid regeneration device with self-cleaning function in one embodiment of the present invention; Figure 6 for Figure 5 Enlarged view of position VIII in the figure.

[0080] from Figure 5 and Figure 6 It can be seen that in this embodiment, the cutting fluid regeneration device with self-cleaning function of the present invention has a plurality of compressed air pipes connected to the compressed air source. In some embodiments, the compressed air pipe 7 is fixed to the cutting fluid tank 27 through a bracket. The tail end of the compressed air pipe has a blowing hole 711, and the blowing direction of the blowing hole 711 is tangent to the radial direction of the cutting fluid tank.

[0081] like Figure 5 As shown, the plurality of compressed air pipes are distributed along the circumferential direction of the cutting fluid groove, and the blowing holes 711 at the tail ends of these compressed air pipes are at different heights in the height direction of the cutting fluid groove. In this embodiment, these compressed air pipes are divided into the first compressed air pipe 71, the second compressed air pipe 72 and the third compressed air pipe 73 according to the different heights of their blowing holes in the height direction of the cutting fluid groove, and are respectively located in the upper layer, the middle layer and the lower layer, wherein the first compressed air pipe 71, the second compressed air pipe 72 and the third compressed air pipe 73 are respectively connected to an independent air path, so as to spray in sequence from top to bottom in the height direction, respectively and independently, and this arrangement and the connection sequence of each compressed air pipe from top to bottom can make the cutting fluid rotate better in the chip groove space to form a vortex.

[0083] Fig.10 A schematic diagram showing the structure of the cutting fluid regeneration device with self-cleaning function according to the present invention in one embodiment with the cutting fluid tank removed; Fig.11 Shows Fig.10 The enlarged view of II in the middle; Fig.12 Shows Fig.10 Enlarged view of point III in the middle.

[0084] like Figure 7 As shown, the cutting fluid regeneration device with self-cleaning function of the present invention further comprises an annular track 2, which is arranged at the periphery of the cutting fluid tank 27. In some embodiments, the annular track 2 can be formed by splicing two semicircles or four sections divided into four equal parts.

[0085] like Fig. 9 and Fig.12 As shown, the lower end of the curved plate slide 6 is slidably connected to the annular track 2, and the curved plate slide 6 extends along the outer wall of the cutting fluid groove 27 in its height direction. In some specific embodiments, the curved plate slide 6 is connected to the annular track 2 through a dovetail slider at the bottom and can slide along the annular track 2.

[0086] like Fig. 9 and Fig.12 As shown, the magnetic head 19 for absorbing cutting particles in the cutting fluid tank is connected to the curved plate slide groove 6 through a bolt 20 and can slide along the curved plate slide groove 6. The movement of the magnetic head 19 is achieved by a magnetic head drive assembly.

[0087] In some embodiments, Fig.12 As shown, the magnetic head driving assembly includes: a magnetic head guide rail 3 connected to the magnetic head 19, and the magnetic head guide rail 3 is also connected to the magnetic head slider 4 through a dovetail groove guide pair, so that the magnetic head slider 4 can slide along the magnetic head guide rail 3, and the tail end of the lever 5 is inserted into the hole of the magnetic head slider 4, and cooperates with the hole gap, so that the lever 5 can rotate in the hole of the magnetic head slider 4. When the lever 5 moves in the height direction of the cutting fluid groove 27, it also rotates around the circumference of the cutting fluid groove 27 at the same time, which drives the magnetic head 19 to move in the height direction of the cutting fluid groove 27 and also move in the circumference direction of the cutting fluid groove along the annular track, forming a spiral ascending compound motion, so as to transport the cutting particles from the bottom of the cutting fluid groove to the annular groove 271 at the upper part of the cutting groove (as shown in FIG. Fig.16 As shown), the cutting particles can then be processed as Fig.17 The drain port 272 is shown to discharge.

[0088] like Figure 8 , Fig.10 and Fig.11As shown, the cutting fluid regeneration device with self-cleaning function also includes a waste liquid bucket 8, a cathode electrode 9 and an anode electrode 10 are fixedly arranged relative to the waste liquid bucket 8, and a waste liquid suction pipe 11 is inserted into the waste liquid bucket 8. In some specific embodiments, the cathode electrode 9 and the anode electrode 10 can be fixed on the top of the middle pipe of the cutting fluid tank 27, and connected to the positive and negative poles of a 3V DC power supply respectively. The waste liquid suction pipe 11 can pass through the middle pipe of the cutting fluid tank 27, and one end of the waste liquid suction pipe 11 is at the same height as the bottom of the cathode electrode 9 and the anode electrode 10.

[0089] Among them, when the cathode electrode 9 and the anode electrode 10 are immersed in the cutting fluid in the cutting fluid tank 27, they adsorb the charged substances in the cutting fluid; when the cathode electrode 9, the anode electrode 10 and the waste liquid bucket 8 leave the cutting fluid under the drive of the waste liquid bucket driving assembly, the cathode electrode 9 and the anode electrode 10 are short-circuited, so that the electrodes lose their adsorption force on positive and negative charges. In this way, the charged substances on the surface of the electrodes fall into the cutting fluid in the waste liquid bucket 8, forming a cutting waste fluid that enriches the chloride ions and metal ions in the cutting fluid into a high ion concentration, and the cutting waste fluid can be discharged through the waste liquid suction pipe 11.

[0090] The up and down movement of the waste liquid bucket 8 is achieved by a waste liquid bucket driving assembly. Fig.13 A schematic structural diagram showing another perspective of a cutting fluid regeneration device with a self-cleaning function according to an embodiment of the present invention.

[0091] like Figure 7 and Fig.13 As shown, in some embodiments, the waste liquid bucket drive assembly includes: upright crooked frame guide rails 26 arranged in pairs; crooked frame sliders 28 arranged in pairs are connected to each crooked frame guide rail 26 with a dovetail groove guide pair to slide in the height direction along the crooked frame guide rails 26, and the crooked frame cross beam 25 is connected between the crooked frame sliders 28 arranged in pairs, one end of the crooked frame 1 is connected to the crooked frame cross beam 25, and the other end is connected to the waste liquid bucket 8.

[0092] In some embodiments, the present invention uses the same set of driving assemblies, and through the transmission components, the driving assembly can drive the waste liquid bucket 8 and the shifting rod 5 to move at the same time.

[0093] like Figure 7 and Fig.13As shown, in some embodiments, the transmission assembly includes: a connecting rod 29, the stepped outer axis circle of the lever 5 is matched with the hole gap at the head end of the connecting rod 29, the nut is connected with the stepped shaft external thread of the lever 5, and the end face of the nut is fitted with the end face of the stepped shaft, and there is a gap between the end face of the nut and the connecting rod 29 to ensure that the lever 5 can rotate in the hole at the head end of the connecting rod 29. The tail end of the connecting rod 29 is rotatably connected to the rotating rod 14 through the rotating shaft 13. The slider 12 is provided with a first through hole and a second through hole perpendicular to each other, wherein the connecting rod 29 passes through the first through hole, and the transmission crossbeam 30 passes through the second through hole and is connected between the paired bending frame sliders 28. In other words, the transmission crossbeam 30 and the connecting rod 29 can slide in the two holes of the slider 12 respectively.

[0094] Fig.14 A side view of a cutting fluid regeneration device with a self-cleaning function according to the present invention is shown in one embodiment; Fig.15 for Fig.14 Enlarged view of the X in the middle.

[0095] like Figure 7 , Fig.10 , Fig.13 As shown, in some embodiments, the drive assembly includes: an upright column 24, on which a vertically extending column guide rail 23 is provided, a motor slider 22 is slidably connected to the column guide rail 23, a servo motor 21 is fixedly connected to the motor slider 22 by bolts and angle irons, and a U-shaped plate 15 is fixedly connected to the motor slider 22 by bolts.

[0096] like Fig.14 and Fig.15 As shown, the gear set 16 includes a first gear 161 and a second gear 162 meshing with each other, wherein the first gear 161 is connected to the output shaft of the servo motor 21 , and the second gear 162 is sleeved on the optical axis of the screw rod 17 so as to rotate coaxially with the screw rod 17 .

[0097] like Figure 7 , Fig.10 , Fig.13 As shown, the screw rod 17 and the screw rod frame 18 are connected to each other through a threaded pair. The screw rod frame 18 is fixed on the ground. The screw rod 17 can move up and down along the screw rod frame 18 during rotation, thereby driving the rotating rod 14 fixedly connected to its top end to rotate around the screw rod axis as the screw rod rotates. The rotating rod 14 is connected to the connecting rod 29 through the rotating shaft 13.

[0098] In this way, when the servo motor 21 drives the gear set 16 to rotate, it will drive the screw 17 to rotate around its own axis, so that the screw 17 performs an upward movement under the cooperation of the screw rod frame 18 thread pair, and then drives the rotating rod 14 to rotate and rise around the screw axis, and further drives the connecting rod 29 to drive the lever 5 to perform a spiral upward compound movement. The lever 5 moves upward while rotating along the outer circumference of the cutting fluid groove through the head slider 4 and the head guide rail 3, thereby driving the magnetic head 19 at the end of the magnetic head guide rail 3 to rotate and move upward. The magnetic head 19 is also guided by the bolt 20 in the curved plate slide groove 6, and finally realizes the spiral upward movement trajectory of the magnetic head 19 along the outer wall of the cutting fluid groove 27. When the magnetic head 19 is at the bottom of the cutting fluid tank 27, the coil in the magnetic head 19 is energized to generate a magnetic field. As the magnetic head 19 spirals upward along the outer wall of the cutting fluid tank 27, the metal debris particles at the bottom of the cutting fluid tank 27 are adsorbed and transported to the drain port 272 at the mouth of the cutting fluid tank 27 for discharge. Fig.16 and Fig.17 shown.

[0099] At the same time, the servo motor 21 drives the rotating rod 14 to rotate and rise around the axis of the screw, and also drives the slider 12 to rise, thereby driving the frame slider 28 to move upward along the frame guide rail 26 through the transmission crossbeam 30, thereby driving the frame crossbeam 25 to drive the frame 1, and then driving the waste liquid bucket 8 to move upward. When the waste liquid bucket 8, the cathode electrode 9, and the anode electrode 10 leave the cutting fluid in the cutting fluid tank 27, the cathode electrode 9 and the anode electrode 10 are short-circuited to each other, so that the electrodes lose their adsorption force on positive and negative charges, and the charged substances on the surface of the electrodes fall into the cutting fluid in the waste liquid bucket 8, forming a waste cutting fluid with high ion concentration enriched with chloride ions and metal ions in the cutting fluid. The waste liquid suction pipe 11 sucks out the cutting fluid with high ion concentration in the waste liquid bucket 8, achieving the purpose of removing metal debris particles and ions.

[0100] As described above, in some embodiments, the compressed air pipe 7 is divided into three layers corresponding to the height direction of the cutting fluid tank 27. 600MPa compressed air is introduced at intervals of 10 seconds from top to bottom. Since the opening direction of the compressed air pipe 7 is tangential to the radial direction of the cutting fluid tank 27, the compressed air introduced in sequence can form a vortex so that the cutting fluid flows between the cathode electrode 9 and the anode electrode 10, thereby promoting the electrical adsorption of ions.

[0101] The combination of the various technical features in this case is not limited to the combination described in the claims of this case or the combination described in the specific embodiments. All technical features recorded in this case can be freely combined or combined in any way unless there is a contradiction between them.

[0102] It should also be noted that the above-listed embodiments are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and similar changes or modifications made therewith can be directly derived or easily associated with by those skilled in the art from the contents disclosed in the present invention, and all should belong to the protection scope of the present invention.
