Description

Technical Field

[0001] This utility model relates to the technical field of cutting fluid filtration equipment, specifically a cutting fluid and debris filtration and separation device for carbon steel gear machining. Background Technology

[0002] In the machining of carbon steel gears, the efficient separation and removal of cutting fluid and chips is crucial for ensuring machining quality and equipment stability. Existing technologies generally employ filtration structures to achieve initial separation of chips and cutting fluid in cutting fluid separation devices. However, these devices commonly suffer from the following problems:

[0003] Untimely cleaning of debris: Traditional filter boxes rely on manual cleaning at regular intervals. However, the debris generated during the machining of carbon steel gears (such as iron filings and grinding wheel particles) has the characteristics of high hardness and easy adhesion. If it is not cleaned in time, it will cause the filter layer to become clogged, affecting the efficiency of cutting fluid circulation, and even causing problems such as accelerated tool wear and reduced machining accuracy. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a cutting fluid and debris filtration and separation device for carbon steel gear machining.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting fluid and chip filtration and separation device for carbon steel gear machining, comprising a machine tool body, a housing at the lower end of the machine tool body, a conduit on one side of the housing, a flow guiding component at the upper end of the machine tool body, and a filter component and a storage component inside the housing, wherein the flow guiding component, the filter component and the storage component are connected in sequence.

[0008] The filter assembly includes a housing and two filter boxes. The housing is fixed to the lower end of the machine tool body and has a placement slot. The two filter boxes are an integrated structure and are slidably connected to the housing through the placement slot. The bottom of the filter box has a filter hole.

[0009] The storage component includes a collection tank and a supply pump. The collection tank is fixed at the lower end of the housing, and the bottom end of the housing is connected to the collection tank via a transfer pipe. The inlet end of the supply pump is equipped with a suction pipe that is inserted into the collection tank, and the outlet end of the supply pump is equipped with an outlet pipe.

[0010] To facilitate the flow of cutting fluid into the placement tank, the present invention includes the following improvements: the flow guiding component includes an annular baffle and multiple inlet holes, which penetrate the machine tool body and communicate with the placement tank. All the inlet holes are located on the inner ring of the annular baffle. The flow guiding component also includes a protrusion, which is fixed to the upper end of the machine tool body and located at the center of the annular baffle. The multiple inlet holes are located on the periphery of the protrusion.

[0011] To facilitate the replacement of the magnetic suction plate, the present invention includes the following improvements: a timer is vertically installed inside the filter box; a positioning seat is provided at the center of the lower end of the magnetic suction plate; a vertical rod is inserted into the positioning seat and threadedly connected to the positioning seat; and the edge of the magnetic suction plate has a beveled structure.

[0012] To facilitate the removal of the filter box from the placement slot, the present invention includes an improvement whereby one of the filter boxes has a frame located at the outer end below the box body, a fixing block in the middle part of the frame, and the drive assembly includes a motor and a lead screw.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a cutting fluid and chip filtration and separation device for carbon steel gear machining, which has the following beneficial effects:

[0015] High-efficiency flow guidance and filtration synergy: In the flow guidance component, the annular baffle and the protrusion form an orderly flow guidance space, and the liquid inlet is precisely aligned with the placement slot to avoid the overflow and waste of cutting fluid; the magnetic plate achieves efficient adsorption of metal debris through magnetic attraction, and the filter holes at the bottom of the filter box further intercept fine impurities, and the dual filtration significantly improves the separation accuracy.

[0016] Continuous, uninterrupted operation: The two integrated filter boxes can work alternately through the linkage of the frame and the fixing block. When one filter box is moved out of the housing by the lead screw, the other immediately takes its place in the placement slot.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention relates to a cutting fluid and debris filtration and separation device for carbon steel gear machining, comprising a machine tool body 1, a housing 5 at the lower end of the machine tool body 1, a conduit 6 on one side of the housing 5, a flow guiding component at the upper end of the machine tool body 1, and a filter component and a storage component inside the housing 5, wherein the flow guiding component, the filter component and the storage component are connected in sequence.

[0026] The filter assembly includes a housing 7 and two filter boxes 13. The housing 7 is fixed to the lower end of the machine tool body 1. The housing 7 is provided with a placement groove 12. The two filter boxes 13 are an integrated structure and are slidably connected to the housing 7 through the placement groove 12. The bottom end of the filter box 13 is provided with a filter hole. The inside of the filter box 13 is provided with a detachable magnetic suction plate 14. The magnetic suction plate 14 is provided with multiple through holes 15. The machine box 5 is provided with a drive assembly for driving the filter box 13 to move. The drive assembly is equipped with a timer 19.

[0027] The storage assembly includes a liquid collection tank 8 and a liquid supply pump 10. The liquid collection tank 8 is fixed at the lower end of the housing 7, and the bottom end of the housing 7 is connected to the liquid collection tank 8 through a transfer pipe 9. The liquid supply pump 10 has a suction pipe inserted into the liquid collection tank 8 at its inlet end, and a liquid outlet pipe 11 at its outlet end.

[0028] The flow guiding assembly includes an annular baffle 2 and multiple liquid inlet holes 4. The multiple liquid inlet holes 4 penetrate the machine tool body 1 and are connected to the placement groove 12. The multiple liquid inlet holes 4 are all located in the inner circle of the annular baffle 2. The flow guiding assembly also includes a protrusion 3. The protrusion 3 is fixed to the upper end of the machine tool body 1 and is located at the center of the annular baffle 2. The multiple liquid inlet holes 4 are respectively located on the periphery of the protrusion 3.

[0029] During the carbon steel gear machining process, the carbon steel gear is machined above the machine tool body 1 by a designated cutting device, and the cutting fluid is sprayed by a spray gun. At this time, the flow guiding component begins to play its role: the annular baffle 2 and the protrusion 3 together guide the cutting fluid to the surrounding inlet holes 4, ensuring that the cutting fluid enters the housing 7 at the lower end of the machine tool body 1 in an orderly manner.

[0030] After the cutting fluid flows into the placement tank 12 of the housing 7 through the inlet hole 4, it enters the filter box 13 which is in operation. It first comes into contact with the magnetic suction plate 14, and then the metal debris in the cutting fluid is adsorbed by the magnetic attraction. The cutting fluid flows out through the through hole 15, and then completes secondary filtration at the filter hole at the bottom of the filter box 13. The filtered clean cutting fluid flows into the collection tank 8 below through the transfer pipe 9.

[0031] The cutting fluid in the collection tank 8 is drawn out through the suction pipe of the supply pump 10 and then transported back to the processing area for recycling through the outlet pipe 11. The conduit 6 on one side of the machine housing 5 is connected to the outlet pipe 11 through a designated pipeline, and the other end of the conduit 6 is connected to the cutting fluid spray gun through a designated pipeline.

[0032] One of the filter boxes 13 has a frame 21 located below the box body 7 at its outer end. The middle part of the frame 21 has a fixing block 22. The drive assembly includes a motor 18 and a lead screw 20. The motor 18 is fixed below the machine tool body 1. The lead screw 20 passes through the fixing block 22 and is threadedly connected to the fixing block 22. One end of the lead screw 20 is connected to the output end of the motor 18 through a coupling. The timer 19 is fixed on one side of the motor 18. The motor 18 has a motor controller, and the timer 19 is connected to the motor controller through an electrical signal.

[0033] When the liquid supply pump 10 starts, the timer 19 starts timing. When the timer 19 reaches the preset time, the motor 18 starts, and its output drives the lead screw 20 to rotate through the coupling. The lead screw 20 is threadedly engaged with the fixing block 22 in the middle of the frame 21, pushing the frame 21 and the connected filter box 13 to slide out of the housing 7 along the placement groove 12. At this time, the other filter box 13 of the integrated structure automatically enters the placement groove 12, ensuring that the filtration process is uninterrupted.

[0034] The filter box 13 has a timer 19 vertically installed inside. The magnetic plate 14 has a positioning seat 16 at the center of its lower end. The vertical rod 17 is inserted into the positioning seat 16 and threadedly connected to it. The edge of the magnetic plate 14 has a beveled structure.

[0035] After the filter box 13 is removed and stops, the magnetic suction plate 14 can be rotated to separate it from the threaded connection between the vertical rod 17 and the positioning seat 16, thereby completing the disassembly and cleaning of the magnetic suction plate 14.

[0036] The beveled edge of the magnetic suction plate 14 facilitates the accumulation of debris. It can be quickly disassembled via the threaded connection between the positioning seat 16 and the vertical rod 17, and can be reinstalled after cleaning, greatly reducing maintenance difficulty. At the same time, the liquid collection tank 8 is connected to the tank body 7 via the adapter pipe 9, and the liquid supply pump 10 draws the filtrate through the suction pipe and circulates it through the discharge pipe 11. Combined with the detachable design, the overall equipment maintenance efficiency is improved.

[0037] The cutting fluid forms a closed-loop circulation with the liquid supply pump 10 through the liquid collection tank 8, reducing resource waste; the double protection of the magnetic suction plate 14 and the filter box 13 prevents debris from entering the liquid supply system, reduces the wear of the liquid outlet pipe 11 and the liquid supply pump 10, and extends the service life of the whole machine.
