Description

Technical Field

[0001] The invention belongs to the technical field of machine tool cleaning, and particularly relates to a device for recycling coolant for machine tools. Background Art

[0002] Computer numerical control machine tools are famous for their high machining accuracy and high machining efficiency. However, a lot of iron filings will be generated during their machining process. The iron filings will fall to the bottom of the machine tool and block the coolant circulation port, resulting in the coolant not being able to circulate for use. Therefore, we propose a device for recycling coolant for machine tools. Summary of the Invention

[0003] The purpose of the invention is to provide a device for recycling coolant for machine tools, which solves the existing problems by separating iron filings.

[0004] To solve the above technical problems, the invention is realized through the following technical solutions: The invention is a device for recycling coolant for machine tools, including a machine tool, a chassis and a movable door. The machine tool is arranged on the top of the chassis, and the movable door is arranged on the outer surface of the machine tool; The machine tool includes a fixed frame, a leakage port, an arc bottom rod, a lower port, an isolation mechanism, a bottom groove, a live water mechanism, a connecting pipe, a water pump, a cooling tank, a cooling pipe and a partition board. The partition board is fixedly connected to the upper and lower inner walls on the left side of the machine tool. The cooling tank is fixedly connected to the bottom of the inner wall on the left side of the machine tool. The water pump is fixedly connected to the bottom of the inner wall of the cooling tank. The right side of the water pump is communicated with a connecting pipe, and the left side of the water pump is communicated with a cooling pipe. The top of the cooling pipe penetrates through the top of the partition board and extends to the inside of the right side of the machine tool. The fixed frame is fixedly connected to the bottom of the left side of the partition board. A bottom groove is opened at one end of the fixed frame close to the bottom of the inner wall of the machine tool. A live water mechanism is arranged on the right side of the connecting pipe. A leakage port is opened at the bottom of the fixed frame, and the number of the leakage ports is six. The left and right inner walls of the fixed frame are fixedly connected with an arc bottom rod. The top of the arc bottom rod is provided with an isolation mechanism. Lower ports are opened at the left and right bottoms of the arc bottom rod.

[0005] Further, the isolation mechanism includes a bent rod, a top port, a compression mechanism, a spring piece, a movable arc rod, a slider one, a slider two and a pressing mechanism. The left and right ends of the top of the arc bottom rod are movably connected with a bent rod through a rotating shaft. Spring pieces are fixedly connected to the left and right outer surfaces of the centers of the two bent rods. The tops of the two bent rods are movably connected with a movable arc rod through a rotating shaft. Top ports are opened at the left and right ends of the top of the movable arc rod. A compression mechanism is arranged at the center of the top of the arc bottom rod. Slider twos are fixedly connected to the bottoms of the left and right ends of the movable arc rod. Slider ones are fixedly connected to the left and right ends of the top of the arc bottom rod. Pressing mechanisms are arranged at the left and right ends of the movable arc rod.

[0006] Furthermore, the compression mechanism includes a fixed frame, an arc pressing rod, a telescopic rod, a swaying rod, a through port, and a spring. The fixed frame is fixedly connected to the top of the arc bottom rod. The bottom of the inner wall of the fixed frame is fixedly connected with a spring. Through ports are opened at both the left and right ends of the fixed frame. A telescopic rod is arranged inside the fixed frame. The telescopic rod penetrates through the top of the fixed frame and is fixedly connected to the bottom of the inner wall of the movable arc rod. The front and rear inner walls of the two through ports are both movably connected with a swaying rod through bearings. One end of the two swaying rods away from each other is movably connected with an arc pressing rod through a rotating shaft.

[0007] Furthermore, the pressing-down mechanism includes a semi-circular rod, an elastic rod, a hanging weight, a sliding rod, and a pressing rod. The center of the top of the semi-circular rod is fixedly connected to the bottom of the arc pressing rod. The center of the bottom of the semi-circular rod is fixedly connected with a hanging weight. A sliding rod is arranged inside the hanging weight. The sliding rod penetrates through the bottom of the hanging weight and extends to the outside. The bottom of the sliding rod is fixedly connected with a pressing rod. The inner walls of the two ends of the semi-circular rod close to each other are both movably connected with an elastic rod through a rotating shaft. One end of the two elastic rods close to each other is movably connected to the left and right outer surfaces of the sliding rod through a rotating shaft.

[0008] Furthermore, the flowing-water mechanism includes a water inlet, a fixed pipe, a rotating rod, a rotating block, a rotating rod groove, and a flowing-water rod. The fixed pipe is communicated with the left side of the connecting pipe. A water inlet is opened at the top right of the fixed pipe. The right side of the fixed pipe is movably connected with a rotating rod through a bearing. Flowing-water rods are fixedly connected to the outer surface of the right side of the rotating rod. A rotating rod groove is opened on the left side of the rotating rod. A rotating block is fixedly connected to the inside of the rotating rod groove.

[0009] Furthermore, the two arc pressing rods both extend to the outside of the movable arc rod through two top ports at the top of the movable arc rod. The bottom of the telescopic rod contacts the outer surfaces of the tops of the two swaying rods.

[0010] Furthermore, the water inlet and the rotating rod groove are horizontally arranged. The flowing-water rod is arranged inside the bottom groove.

[0011] The present invention has the following beneficial effects: In the present invention, a movable arc rod is arranged at the center of the top of the arc bottom rod. The iron filings are separated to the left and right ends of the top of the arc bottom rod through the movable arc rod, avoiding the iron filings from blocking the lower opening and resulting in the coolant being blocked and unable to be recycled.

[0012] In the present invention, when the coolant is on the surface of the arc-bottom rod, the coolant will enter the interior of the movable arc rod through the first slider. When a large amount of iron filings accumulate on the surface of the arc-bottom rod, they will block the surface of the first slider, causing the coolant to be unable to enter the interior of the movable arc rod. When the movable arc rod is under the pressure of the iron filings, it will move downward. Through the movement of the movable arc rod, the second slider will move on the surface of the first slider, preventing the iron filings from blocking the surface of the first slider.

[0013] In the present invention, when the movable arc rod moves downward, the two end second sliders will come into contact with the surface of the arc-bottom rod. When the two second sliders come into contact with the surface of the arc-bottom rod, vibrations will be generated, and the iron filings on the surface of the movable arc rod will fall onto the surface of the arc-bottom rod through the vibrations. This causes the first slider and the second slider to separate, increasing the fluidity of the coolant.

[0014] In the present invention, when the arc pressing rod presses downward, it will squeeze the surface of the semi-circular rod. When the semi-circular rod is under pressure, it will expand towards both ends. When the semi-circular rod expands, it will pull the sliding rod downward through the elastic rod. Through the movement of the sliding rod, the pressing rod will squeeze the iron filings, preventing the coolant from adhering to the surface of the iron filings.

[0015] In the present invention, when the water pump is started, the fixed pipe will suck the coolant into the interior of the water pump through the water inlet. The coolant will impact the surface of the rotating block through the suction force, and the rotating block will drive the rotating rod to rotate through the impact force, causing the movable water rod to stir the coolant inside the bottom groove, preventing the coolant from precipitating inside the bottom groove and resulting in poor coolant performance.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The partition plate 21 is fixedly connected to the upper and lower inner walls on the left side of the machine tool 1. The cooling tank 19 is fixedly connected to the bottom of the inner wall on the left side of the machine tool 1. The water pump 18 is fixedly connected to the bottom of the inner wall of the cooling tank 19. A connecting pipe 17 is communicated with the right side of the water pump 18. A cooling pipe 20 is communicated with the left side of the water pump 18. The top of the cooling pipe 20 penetrates through the top of the partition plate 21 and extends to the inside on the right side of the machine tool 1. The fixed frame 10 is fixedly connected to the bottom left side of the partition plate 21. A bottom groove 15 is opened at one end of the fixed frame 10 close to the bottom of the inner wall of the machine tool 1. A live water mechanism 16 is arranged on the right side of the connecting pipe 17. A leakage port 11 is opened at the bottom of the fixed frame 10. The number of the leakage ports 11 is six. The left and right inner walls of the fixed frame 10 are fixedly connected with an arc-bottom rod 12. An isolation mechanism 14 is arranged on the top of the arc-bottom rod 12. Lower ports 13 are opened at the left and right bottoms of the arc-bottom rod 12. In the present invention, a movable arc rod 145 is arranged at the center of the top of the arc-bottom rod 12. The iron filings are separated at the left and right ends of the top of the arc-bottom rod 12 through the movable arc rod 145, so as to avoid the iron filings blocking the lower ports 13, resulting in the coolant being blocked and unable to be recycled.

[0023] The isolation mechanism 14 includes a bending rod 141, a top opening 142, a compression mechanism 143, a spring 144, a movable arc rod 145, a slider 146, a slider 2 147 and a pressing mechanism 148. The left and right ends of the top of the arc bottom rod 12 are movably connected to the bending rod 141 through a rotating shaft. The left and right outer surfaces of the centers of the two bending rods 141 are fixedly connected to the spring 144.

Slide blocks 147 are fixedly connected to the bottoms of the left and right ends of the movable arc rod 145. When the movable arc rod 145 moves downward, the slide blocks 147 at both ends will contact the surface of the arc bottom rod 12. When the two slide blocks 147 contact the surface of the arc bottom rod 12, vibration will be generated, and the iron filings on the surface of the movable arc rod 145 will slide onto the surface of the arc bottom rod 12 through the vibration. The slider 146 and the slider 2 147 are separated to increase the fluidity of the coolant. The left and right ends of the top of the arc bottom rod 12 are fixedly connected with the slider 146, and the left and right ends of the movable arc rod 145 are provided with a downward pressing mechanism 148. When the coolant is on the surface of the arc bottom rod 12, the coolant will enter the interior of the movable arc rod 145 through the slider 1 146. When a large amount of iron filings gather on the surface of the arc bottom rod 12, they will be blocked on the surface of the slider 1 146, resulting in the coolant being unable to enter the interior of the movable arc rod 145. When the movable arc rod 145 is subjected to the pressure of the iron filings, it will move downward. Through the movement of the movable arc rod 145, the slider 2 147 will move on the surface of the slider 1 146 to prevent the iron filings from being blocked on the surface of the slider 1 146.

[0024] The compression mechanism 143 includes a fixed frame c1, an arc pressure rod c2, a telescopic rod c3, a rocking rod c4, a through hole c5 and a spring c6. The fixed frame c1 is fixedly connected to the top of the arc bottom rod 12, and the bottom of the inner wall of the fixed frame c1 is fixedly connected to the spring c6. The left and right ends of the fixed frame c1 are provided with through holes c5. The fixed frame c1 is provided with a telescopic rod c3 inside. The telescopic rod c3 passes through the top of the fixed frame c1 and is fixedly connected to the bottom of the inner wall of the movable arc rod 145. The front and rear inner walls of the two through holes c5 are movably connected to the rocking rod c4 through bearings, and the ends of the two rocking rods c4 that are away from each other are movably connected to the arc pressure rod c2 through a rotating shaft.

[0025] The pressing mechanism 148 includes a semi-circular rod d1, an elastic rod d2, a hanging block d3, a sliding rod d4, and a pressing rod d5. The center of the top of the semi-circular rod d1 is fixedly connected to the bottom of the arc pressing rod c2. The center of the bottom of the semi-circular rod d1 is fixedly connected to a hanging block d3. A sliding rod d4 is arranged inside the hanging block d3. The sliding rod d4 penetrates the bottom of the hanging block d3 and extends to the outside. The bottom of the sliding rod d4 is fixedly connected to a pressing rod d5. The inner walls of the mutually close ends of the semi-circular rod d1 are both movably connected to an elastic rod d2 through a rotating shaft. The mutually close ends of the two elastic rods d2 are both movably connected to the left and right outer surfaces of the sliding rod d4 through a rotating shaft. In the present invention, when the arc pressing rod c2 presses downward, it will squeeze the surface of the semi-circular rod d1. When the semi-circular rod d1 is under pressure, it will expand towards both ends. When the semi-circular rod d1 expands, it will pull the sliding rod d4 downward through the elastic rod d2. Through the movement of the sliding rod d4, the pressing rod d5 will squeeze the iron filings, preventing the coolant from adhering to the surface of the iron filings.

[0026] The flowing water mechanism 16 includes a water inlet a1, a fixed pipe a2, a rotating rod a3, a rotating block a4, a rotating rod groove a5, and a flowing water rod a6. The fixed pipe a2 is communicated with the left side of the connecting pipe 17. The top of the right side of the fixed pipe a2 is provided with a water inlet a1. The right side of the fixed pipe a2 is movably connected to a rotating rod a3 through a bearing. The outer surface of the right side of the rotating rod a3 is fixedly connected with flowing water rods a6. A rotating rod groove a5 is opened on the left side of the rotating rod a3. A rotating block a4 is fixedly connected to the inside of the rotating rod groove a5. In the present invention, when the water pump is started, the fixed pipe a2 will suck the coolant into the inside of the water pump through the water inlet a1. The coolant will impact the surface of the rotating block a4 through the suction force. The rotating block a4 will drive the rotating rod a3 to rotate through the impact force, so that the flowing water rods a6 will stir the coolant inside the bottom groove 15, preventing the coolant from precipitating inside the bottom groove 15 and resulting in poor coolant effect.

[0027] Both of the two arc pressing rods c2 extend to the outside of the movable arc rod 145 through the two top openings 142 at the top of the movable arc rod 145. The bottom of the telescopic rod c3 contacts the outer surfaces of the tops of the two shaking rods c4.

[0028] The water inlet a1 and the rotating rod groove a5 are horizontally arranged, and the flowing water rods a6 are arranged inside the bottom groove 15.

[0029] A specific application of this embodiment is as follows: When the machine tool 1 is working, a large amount of cutting iron filings will be generated. During cutting, coolant is used to cool the tool, and the coolant will enter the interior of the arc-bottom rod 12 and enter the interior of the lower opening 13 through the gap between the first slider 146 and the second slider 147. Inevitably, when iron filings accumulate on the surface of the arc-bottom rod 12, the first slider 146 will be blocked. The iron filings generated during cutting will squeeze the surface of the movable arc rod 145, and the movable arc rod 145 will move downward due to gravity, causing the second slider 147 to move on the surface of the first slider 146 to clean the iron filings on the surface of the first slider 146. When the movable arc rod 145 moves, the telescopic rod c3 will press down on the two shaking rods c4. When the two ends of the shaking rod c4 are lifted upward due to gravity, they will squeeze the arc pressing rods c2 at both ends. When the arc pressing rod c2 is squeezed, the semi-circular rod d1 will fit on the surface of the arc-bottom rod 12. When the semi-circular rod d1 is under pressure, it will expand towards both ends, and the two ends of the semi-circular rod d1 will pull the two elastic rods d2 to move downward, causing the two elastic rods d2 to pull the pressing rod d5 towards the surface of the arc-bottom rod 12 through the sliding rod d4, so that the pressing rod d5 will squeeze the iron filings to prevent the coolant from adhering to the surface of the iron filings.
