Description

Technical Field

[0001] This utility model belongs to the technical field of oil and chip separation and circulation devices, and in particular relates to an oil and chip separation and circulation device for CNC machine tools. Background Technology

[0002] Machine tools are machines used to manufacture machines, also known as machine tools or machine tools. They are generally classified into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools. In modern mechanical manufacturing, there are many methods for processing mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. However, parts with high precision requirements and fine surface roughness requirements generally need to be finally processed by cutting methods on machine tools. Machine tools play an important role in the modernization of the national economy. During the use of machine tools, coolant is needed to continuously flush the equipment to reduce the temperature. During the cooling process, the lubricating oil on the equipment and the metal shavings generated during processing will mix into the coolant. In order to improve the utilization rate of coolant, it is necessary to recycle it. Therefore, an oil and shavings separation and circulation device for CNC machine tools is proposed. Utility Model Content

[0003] The purpose of this invention is to provide an oil and chip separation and circulation device for CNC machine tools. Specifically, a motor drives a fixed plate to rotate via a shaft. As the fixed plate rotates, a support tube drives an impact rod to strike an impact block. The impact rod, through the spring's rebound force, continuously impacts the impact block, achieving a vibration effect on the filter screen. This filters iron filings and impurities from the coolant. The filtered coolant then passes through the support plate and float ball, and oil and chips are skimmed off through the drain hose. The coolant after oil and chip separation is discharged through the drain pipe and recycled. This solves the problem that during machine tool operation, the equipment needs to be constantly flushed with coolant to reduce its temperature. However, during the cooling process, lubricating oil and metal filings from the machining process mix into the coolant, reducing its utilization rate.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an oil and chip separation and circulation device for CNC machine tools, comprising a main frame mechanism, a separation cylinder, a cooling assembly on the outside of the separation cylinder, and a separation component inside the separation cylinder. The separation component includes a motor, the top of which is fixedly connected to the bottom of the separation cylinder. A rotating shaft is rotatably connected inside the separation cylinder. A filter screen is fitted onto the top of the outer surface of the rotating shaft. Several impact blocks are fixedly connected to the bottom of the filter screen. A fixing plate is provided at the bottom of the filter screen. Several support tubes are fixedly connected to the top of the fixing plate. Impact rods are slidably connected inside each of the support tubes. The side of each impact rod away from the support tube contacts the side of the impact block away from the filter screen. A spring is fixedly connected to the bottom of each impact rod. The end of the spring away from the impact rod is fixedly connected to the inner wall of the support tube. The inside of the fixed plate is fixedly connected to the outer surface of the rotating shaft. A guide plate is provided at the bottom of the fixed plate, and a support plate is provided at the bottom of the guide plate. Several floats are fixedly connected to the top of the support plate, and an oil drain hose is fixedly connected to the bottom of the support plate. The starter motor drives the fixed plate to rotate through the rotating shaft. When the fixed plate rotates, it drives the impact rod to strike the impact block through the support tube. At this time, the impact rod will continuously strike the impact block through the spring rebound force, realizing the vibration effect of the filter screen and filtering iron filings and impurities in the coolant. After the coolant is filtered, it passes through the support plate and floats, and the oil filings in the coolant will be skimmed out through the oil drain hose. The coolant after oil filings separation is discharged through the drain pipe and recycled.

[0006] Furthermore, a baffle is provided at the bottom of the support plate. The outer ring of the baffle is fixedly connected to the inner wall of the separator cylinder, and the inside of the baffle is rotatably connected to the outer surface of the rotating shaft. The oil drain hose passes through the baffle and extends to the bottom of the separator cylinder. The inside of the baffle is fixedly connected to the outer surface of the oil drain hose by a sealing ring. The inside of the guide plate is rotatably connected to the outer surface of the rotating shaft, and the outer ring of the guide plate is fixedly connected to the inner wall of the separator cylinder. When the rotating shaft rotates, it will cause the coolant to float slightly. At this time, the support plate will always float above the coolant through the action of the float ball. At this time, the oil stains in the coolant will flow into the inside of the oil drain hose through the support plate, and then be discharged to the outside of the separator cylinder for collection and treatment through the oil drain hose.

[0007] Furthermore, a magnetic block one is provided on the top of the guide plate. The outer ring of the magnetic block one is fixedly connected to the inner wall of the separation cylinder. A magnetic block two is in contact with the top of the magnetic block one. The top of the magnetic block two is fixedly connected to the bottom of the filter screen. Handles are fixedly connected to the left and right sides of the top of the filter screen. A drain pipe is fixedly connected to the left side of the bottom of the baffle. An electric control valve is provided inside the drain pipe. The drain pipe passes through the separation cylinder and extends to the bottom. The top output end of the motor is fixedly connected to the bottom of the rotating shaft through a coupling. The operator can control the time when the coolant is discharged from the drain pipe to the outside through the electric control valve.

[0008] Furthermore, a support ring is fixedly connected to the top of the outer surface of the separation cylinder, and several through holes are opened inside the support ring. A cover plate is provided on the top of the separation cylinder, and a feed inlet is fixedly connected to the top of the cover plate. The bottom of the cover plate contacts the top of the support ring. The operator can open the cover plate and then take out the filter screen by the handle. At this time, the impurities on the surface of the filter screen can be cleaned.

[0009] Furthermore, the cooling assembly includes a water storage tank, the inner wall of which is fixedly connected to the outer surface of the separation cylinder. A water pump is installed on the top left side of the water storage tank. Connecting pipes are fixedly connected to both the inlet and outlet ends of the water pump. The side of the connecting pipe at the inlet end, away from the water pump, is fixedly connected to the top of the water storage tank. A cavity is formed inside the separation cylinder, and a water-cooling pipe is installed inside the cavity. The inlet of the water-cooling pipe is fixedly connected to the connecting pipe at the outlet end, and a return pipe is fixedly connected to the outlet end of the water-cooling pipe. The side of the return pipe away from the water-cooling pipe is fixedly connected to the left side of the bottom of the water storage tank. A water injection pipe is fixedly connected to the top right side. Liquid is injected into the water storage tank through the water injection pipe. Then, the water pump is started to draw the liquid out of the water storage tank through the inlet pipe and simultaneously transport the liquid into the water cooling pipe through the outlet pipe for circulation. This achieves heat exchange with the coolant inside the separator, cooling the coolant inside the separator and enabling rapid use of the coolant, thus improving work efficiency. After heat exchange, the liquid flows back into the water storage tank through the return pipe for reuse. The circulation reduces resource waste and further improves the heat exchange effect.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model, through the setting of a separation component, specifically, involves a starting motor driving a fixed plate to rotate via a shaft. When the fixed plate rotates, it drives an impact rod to strike an impact block via a support tube. At this time, the impact rod, under the action of spring rebound force, continuously impacts the impact block, achieving the vibration effect of the filter screen. This filters iron filings and impurities in the coolant. The filtered coolant, through the action of the support plate and float ball, has oil filings skimmed off through the oil drain hose. The coolant after oil filings separation is discharged through the drain pipe and recycled, significantly improving the utilization rate of coolant, greatly reducing resource waste, and reducing the financial expenditure of enterprises.

[0012] 2. This utility model, through its design, specifically involves activating a water pump to extract liquid from the storage tank and send it through a connecting pipe into the water-cooling pipe, thereby achieving heat exchange inside the separator. This allows the coolant inside the separator to cool down rapidly. The liquid after heat exchange flows back into the storage tank through a return pipe for reuse, reducing liquid waste while improving the heat exchange effect. The coolant can be reused after rapid cooling, significantly improving the practicality of the equipment and greatly increasing work efficiency.

[0027] Cooling assembly 2 includes a water storage tank 211. The inner wall of the water storage tank 211 is fixedly connected to the outer surface of the separation cylinder 111. A water pump 212 is installed on the top left side of the water storage tank 211. A connecting pipe 213 is fixedly connected to both the inlet and outlet ends of the water pump 212. The side of the connecting pipe 213 at the inlet end that is away from the water pump 212 is fixedly connected to the top of the water storage tank 211. A cavity 216 is opened inside the separation cylinder 111. A water cooling pipe 215 is installed inside the cavity 216.

One side of 5 is fixedly connected to the left side of the bottom of the water storage tank 211, and the right side of the top of the water storage tank 211 is fixedly connected to the water injection pipe 217. When the water pump 212 is started, the liquid inside the water storage tank 211 is drawn out and sent into the water cooling pipe 215 through the connecting pipe 213, so as to realize heat exchange inside the separator 111, which makes the coolant inside the separator 111 cool down quickly. The liquid after heat exchange will flow back into the water storage tank 211 through the return pipe 214 for reuse, reducing liquid waste and improving heat exchange effect. The coolant can be reused after rapid cooling, which greatly improves the practicality of the equipment and greatly improves the work efficiency.

[0028] A specific application of this embodiment is as follows: In use, firstly, the filter screen 315 is placed inside the separator cylinder 111 via the handle 323, and simultaneously, the filter screen 315 is placed over the rotating shaft 314. At this time, the magnetic block 321 at the bottom of the filter screen 315 will adhere to the magnetic block 320 on the inner wall of the separator cylinder 111. Then, the cover plate 112 is fixedly connected to the support ring 114. At this time, the used coolant can be added into the separator cylinder 111 through the feed port 113. Then, the motor 311 is started to drive the rotating shaft 314 to rotate. When the rotating shaft 314 rotates, it will drive the fixing plate 322 to rotate. At the same time, the rotation of the fixing plate 322 will drive the impact rod 326 to rotate through the support tube 327. When the impact rod 326 rotates, it will impact... When block 325 impacts, the force exerted on block 325 will exert a force on filter screen 315, causing filter screen 315 to vibrate. Simultaneously, impact rod 326 will also be subjected to force and move inwards towards support tube 327. When impact rod 326 moves, it will compress spring 328. Spring 328, limited by support tube 327, will contract and store force. Simultaneously, spring 328 will generate a certain rebound force, causing impact rod 326 to reset. This achieves the effect of continuous impact of impact rod 326 on impact block 325. Filter screen 315 filters impurities in the coolant, and the vibration effect of filter screen 315 prevents impurities from clogging it. After a period of use... The operator can open the cover 112 and then remove the filter screen 315 through the handle 323. At this time, impurities on the surface of the filter screen 315 can be cleaned. After filtration, the coolant flows downwards, and then flows downwards after being guided by the guide plate 316. The operator can control the time the coolant stays at the top of the baffle 318 through the electronic control valve 319. Since oil stains in the coolant will float on top, the rotation of the shaft 314 will cause the coolant to float slightly. The support plate 317, through the action of the float ball 324, will always float above the coolant. The oil stains in the coolant will then flow through the support plate 317 into the drain hose 313, and then be discharged from the outside of the separator 111. For collection and processing, the operator can control the time it takes for the coolant to be discharged from the drain pipe 312 via the electric control valve 319. Simultaneously with coolant separation, the operator first injects liquid into the storage tank 211 through the water injection pipe 217, then starts the water pump 212 to draw out the liquid from the storage tank 211 through the inlet connection pipe 213. Simultaneously, the liquid is transported through the outlet connection pipe 213 into the water-cooling pipe 215 for circulation, achieving heat exchange with the coolant inside the separator 111, thus cooling the coolant and enabling rapid use of the coolant, improving work efficiency. The liquid after heat exchange flows back into the storage tank 211 through the return pipe 214 for reuse.Circulating flow reduces resource waste while further improving heat exchange efficiency.
