Description

Technical Field

[0001] This invention relates to the field of metal machining equipment technology, specifically to a cutting fluid-based supply device and operating method. Background Technology

[0002] Cutting fluid is an industrial liquid primarily used in metal cutting and grinding processes to cool and lubricate the cutting tools and workpieces. It is a scientifically formulated blend of various high-performance additives, possessing excellent cooling, lubrication, rust prevention, degreasing and cleaning properties, corrosion resistance, and easy dilution. During machine tool processing, the cutting area generates a significant amount of heat, necessitating the use of cutting fluid to cool the tools.

[0003] Existing cutting fluid-based supply equipment and operating methods still have the following problems. Existing devices generally filter impurities in the cutting fluid by using a filter cartridge or installing a filter screen in the pipeline. For example, Chinese patent CN107127638A discloses a cutting fluid supply system with multiple supply routes, which can supply cutting fluid to multiple metal processing equipment at the same time.

[0004] However, the above-mentioned technical device filters impurities in the cutting fluid using a filter cartridge before supplying the fluid. But the cleanliness requirements of the cutting fluid may vary when processing different workpieces. When performing rough machining, the cutting fluid often contains large-sized impurity particles, and using a fine filter screen may cause clogging. Therefore, it is necessary to adjust the size and gap of the filter screen to adapt to different processing needs. However, when changing filter cartridges of different specifications, the above-mentioned device requires a cumbersome disassembly process, which is time-consuming and labor-intensive, affecting the working efficiency of the device. In order to solve this problem, we urgently need to find a more convenient and efficient way to replace filter cartridges, so as to reduce the burden on operators, improve the overall performance of the device, and ensure the smooth operation of the production process.

[0020] Step 1: Pour the cutting fluid into the reservoir through the inlet pipe to ensure proper storage and provide stable lubrication and cooling for subsequent machining operations;

[0021] Step 2: When the cutting fluid enters the storage tank, it flows into the filter assembly. As the cutting fluid flows into the filter assembly, it is filtered to remove iron filings and impurities. When in use, connect the equipment to power, connect the input end of the water pump to the left side of the filter assembly, and connect the output end to the machine tool. Then, control the filter assembly to open and discharge the filtered cutting fluid through the controller. At the same time, turn on the water pump to pressurize the cutting fluid to facilitate cooling of the machine tool's cutting tools.

[0022] Step 3: When the machine tool performs rough and fine machining on different workpieces, the controller controls the drive assembly to start, and then the switching assembly is inserted into the drive assembly to drive the switching assembly to rotate and switch the filter screens with different gaps to meet the machining requirements. During rotation, the limit assembly can limit the rotation angle of the switching assembly and separate the switching assembly from the drive assembly to limit and fix the switched filter screen.

[0023] Step 4: After the filter screen has been rotated and switched, the filter screen that has filtered out the impurities will rotate to the front of the cleaning component. At this time, the drive component will drive the cleaning component to remove the impurities accumulated on the filter screen and clean them out of the device.

[0024] Preferably, before the switching component is inserted into the drive component, the controller needs to control the limit component to release the position restriction of the filtering component on the switching component.

[0025] Beneficial effects

[0026] This invention provides a cutting fluid-based supply device and operating method. Compared with the prior art, it has the following advantages:

[0027] 1. This cutting fluid supply device and operating method facilitates quick replacement of filters of different specifications through the use of spring pins and movable columns. When it is necessary to change the filter specifications according to the roughing and fine machining conditions, the drive assembly is activated to rotate the mounting cylinder. Then, the L-shaped clamping plate is pinched and the retaining spring is pressed inward, causing the right side of the L-shaped clamping plate to move away from the left side of the switching cylinder. At this time, the elastic force of the first spring will push the movable column to the right and press it against the left side of the mounting cylinder. When the mounting cylinder rotates to a certain angle, the spring pin will pass through the slot, allowing the right end of the movable column to be inserted into the interior of the mounting cylinder. When the spring pin moves to the right, it will be subjected to the insertion... The compression of the groove causes the spring pin to enter the interior of the mounting groove. When the spring pin moves to the right into the interior of the arc-shaped groove, it will pop out of the interior of the mounting groove. At this time, the spring pin will drive the switching cylinder to rotate along the trajectory of the arc-shaped groove, causing the filter assembly to rotate and switch. Then, the limiting component limits the spring pin to drive the movable column to rotate out of the interior of the mounting cylinder. At the same time, the movable column will push the L-shaped clamping plate out of the interior of the switching cylinder and fix the position of the switching cylinder through the limiting component to complete the switching. At this time, the spring force of the clamping spring can lock the L-shaped clamping plate on the left side of the switching cylinder to fix the position of the movable column, which facilitates switching, reduces the burden on operators, and improves the working efficiency of the device.

[0028] 2. The cutting fluid supply equipment and operating method, through the set filter components, can prevent the filtered impurities from flowing back into the storage tank or remaining inside the outlet pipe. During use, the filter screen can filter out impurities inside the cutting fluid. The filtered impurities will accumulate and adhere to the front side of the filter screen. When too much impurities accumulate, the impact of the water flow will carry the impurities to the annular groove formed by the front side of the perforated ring plate and the outer side of the filter screen for storage, preventing the impurities from flowing back into the storage tank or remaining inside the outlet pipe, and ensuring smooth and unobstructed water flow.

[0029] 3. This cutting fluid-based supply device and operating method uses a cleaning brush to clean debris from the filter screen and the right side of the perforated ring plate. When the switching component drives the filter component to complete the switching, the filtered filter screen will rotate and move to the front of the cleaning disc. At this time, the drive component is still rotating, and then drives the cleaning disc to clean the debris from the filter screen and the right side of the perforated ring plate by rotating the cleaning brush. After cleaning, the cleaning door can be opened to remove the debris remaining inside the protective shell. The operation is simple and quick, greatly improving the convenience of use and making the cleaning work more efficient and easy. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides three technical solutions:

[0045] Figures 1-8 The first embodiment is shown: a cutting fluid supply device, including a reservoir 1, a controller 2 fixedly mounted on the front of the reservoir 1, and the controller 2 is a PLC used to control the coordinated operation of various components inside the device. A supply mechanism 3 is provided on the left side of the reservoir 1 for filtering and supplying cutting fluid for the machine tool. The supply mechanism 3 includes:

[0046] The filter assembly 31 is located on the left side of the liquid storage tank 1 and is used to filter iron filings and debris in the cutting fluid.

[0047] The drive assembly 32, located on the right side of the inner cavity of the protective housing 311, is used to provide power for switching and cleaning the filter 318;

[0048] The switching assembly 33 is located inside the protective shell 311 to facilitate the switching of the filter screen 318. The switching assembly 33 includes a fixed seat 331 fixedly installed on the right side of the inner cavity of the protective shell 311. An installation cylinder 332 is movably installed on the inner side of the fixed seat 331. An arc-shaped groove 333 and a slot 334 are provided on the inner wall of the installation cylinder 332. A switching cylinder 338 is movably installed on the left side of the inner cavity of the fixed seat 331. A connecting column 3311 is movably installed inside the switching cylinder 338. Two L-shaped clamping plates 339 are fixedly installed on the left side of the connecting column 3311. A retaining spring 3310 is fixedly installed on the opposite side of the two L-shaped clamping plates 339. A movable column 337 is fixedly installed on the right side of the connecting column 3311. An installation groove 336 is provided on the right end of the outer side of the movable column 337. A spring pin 335 is movably installed inside the installation groove 336. A fixing ring 3312 is fixedly installed on the inner side of the switching cylinder 338. A first spring 3313 is fixedly installed on the right side of the fixing ring 3312.

[0049] The cleaning component 34 is located on the right side of the inner cavity of the protective shell 311 and is used to clean debris on the filter screen 318;

[0050] The limiting component 35 is located on the outside of the switching cylinder 338 to limit the rotation angle of the switching cylinder 338. The left ends of the arc-shaped groove 333 and the slot 334 both penetrate the interior of the mounting cylinder 332 and extend to the left side of the mounting cylinder 332. The right end of the arc-shaped groove 333 penetrates the outside of the slot 334 and extends to the inside of the slot 334. The right end of the slot 334 is narrower. When the spring pin 335 enters the slot 334 and continues to slide to the right, it will press the spring pin 335 into the mounting groove 336. When the spring pin 335 reaches the arc-shaped groove 333, it will pop out again and slide out of the interior of the arc-shaped groove 333 as the mounting cylinder 332 rotates. The left ends of the two L-shaped plates 339 both move through the interior of the switching cylinder 338 and extend... To the left side of the switching cylinder 338, the right sides of both switching cylinders 338 are tightly pressed against the left side of the switching cylinder 338, and the elastic force of the retaining spring 3310 can make the two L-shaped retaining plates 339 abut against the left side of the switching cylinder 338 to fix the position of the connecting column 3311. The front end of the spring pin 335 moves through the interior of the mounting groove 336 and extends to the outside of the mounting groove 336. The right side of the movable column 337 moves through the interior of the switching cylinder 338 and extends to the right side of the switching cylinder 338. The first spring 3313 is movably fitted on the outside of the connecting column 3311. The right end of the fixing ring 3312 is fixedly installed on the left side of the movable column 337, and the elastic force of the fixing ring 3312 can abut against the movable column 337 and insert it into the interior of the mounting cylinder 332.

[0051] The spring pin 335 and movable column 337 facilitate quick replacement of filter screens 318 of different specifications. When it is necessary to change the filter screen 318 specification according to the coarse and fine machining conditions, the drive assembly 32 is activated to rotate the mounting cylinder 332. Then, the L-shaped clamping plate 339 is pinched and the clamping spring 3310 is pressed inward, causing the right side of the L-shaped clamping plate 339 to move away from the left side of the switching cylinder 338. At this time, the elastic force of the first spring 3313 will push the movable column 337 to the right and press it against the left side of the mounting cylinder 332. When the mounting cylinder 332 rotates to a certain angle, the spring pin 335 will pass through the slot 334 to insert the right end of the movable column 337 into the interior of the mounting cylinder 332. When the spring pin 335 moves to the right, it will be squeezed by the slot 334, causing the spring pin 335 to... When the spring pin 335 moves to the right into the arc-shaped groove 333, it will pop out of the mounting groove 336. At this time, the spring pin 335 will drive the switching cylinder 338 to rotate along the trajectory of the arc-shaped groove 333, causing the filter component 31 to rotate and switch. Then, the limiting component 35 limits the spring pin 335 to drive the movable column 337 to rotate out of the mounting cylinder 332. At the same time, the movable column 337 will push the L-shaped clamping plate 339 out of the switching cylinder 338 and fix the position of the switching cylinder 338 through the limiting component 35 to complete the switching. At this time, the spring force of the clamping spring 3310 can lock the L-shaped clamping plate 339 on the left side of the switching cylinder 338 to fix the position of the movable column 337, which facilitates switching, reduces the burden on operators, and improves the working efficiency of the device.

[0052] Figures 1-5The second embodiment is shown, and its main difference from the first embodiment is that the filter assembly 31 further includes a water outlet pipe 312 fixedly installed inside the protective shell 311. A groove 316 is formed on the top surface of the water outlet pipe 312. A solenoid valve pipe 313 is fixedly installed on the left side of the water outlet pipe 312. Three outer cylinders 3111 are fixedly installed on the outside of the switching cylinder 338, and the three outer cylinders 3111 are evenly distributed circumferentially on the outside of the switching cylinder 338. The inner cavities of the three outer cylinders 3111 are all fixed on the side closest to the switching cylinder 338. A fixed electric telescopic rod 314 is installed. An inner cylinder 315 is movably installed inside each of the three outer cylinders 3111. An arc-shaped plate 317 is fixedly installed at one end of each inner cylinder 315, and the arc-shaped plate 317 matches the size of the groove 316. Sealing gaskets are fixedly installed on both sides of the arc-shaped plate 317. A fixed cylinder 3110 is fixedly installed on the bottom surface of the arc-shaped plate 317. A perforated ring plate 319 is fixedly installed on the inner side of the fixed cylinder 3110. A filter screen 318 is fixedly installed on the inner side of the perforated ring plate. The pore size of the filter screen 318 is adapted to the gap size of the filter screen 318. Different filter screens 318 have different gap sizes. The perforated ring plate 319 is fixedly installed on the left side of the outer side of the filter screen 318 so that the filtered debris can adhere to the right side of the filter screen 318 or the annular groove formed by the perforated ring plate 319 and the outer side of the filter screen 318. The output end of the fixed electric telescopic rod 314 is fixedly installed on the end of the inner cavity of the inner cylinder 315 away from the three outer cylinders 3111. One end of the inner cylinder 315 moves through the interior of the three outer cylinders 3111 and is fixedly installed on the arc. The outer side of the curved plate 317, and the activation of the fixed electric telescopic rod 314 can drive the inner cylinder 315 to pull the filter screen 318 out of the water outlet pipe 312 through the curved plate 317 for easy replacement. The right end of the water outlet pipe 312 penetrates the interior of the protective shell 311 and extends into the interior of the liquid storage tank 1. The left end of the water outlet pipe 312 penetrates the interior of the protective shell 311 and is fixedly installed at the right end of the solenoid valve pipe 313. When the solenoid valve pipe 313 is opened, the filtered cutting fluid can be delivered to the machine tool for use through the water outlet pipe 312.

[0053] The filter assembly 31 prevents filtered debris from flowing back into the reservoir 1 or stagnating inside the outlet pipe 312. During use, the filter screen 318 filters out debris from the cutting fluid. The filtered debris accumulates and adheres to the front of the filter screen 318. When too much debris accumulates, the impact of the water flow will carry the debris to the annular groove formed by the front of the perforated ring plate 319 and the outer side of the filter screen 318 for storage, preventing the debris from flowing back into the reservoir 1 or stagnating inside the outlet pipe 312, and ensuring smooth and unobstructed water flow.

[0054] Figure 2 and Figures 9-12The third embodiment is shown, and its main difference from the second embodiment is that the drive assembly 32 includes a DC motor 323 and a support member 324 fixedly installed on the right side of the inner cavity of the protective shell 311. A shaft 322 is fixedly installed at the output end of the DC motor 323. A drive bevel gear 321 is fixedly installed on the outer side of the shaft 322. A double bevel gear shaft 325 is movably installed on the inner side of the support member 324, and the stability of the double bevel gear shaft 325 during rotation can be limited by the support member 324. The front end of the double bevel gear shaft 325 meshes with a driven bevel gear shaft 326. The left end of the shaft 322 is fixedly installed on the right side of the mounting cylinder 332, and the rear end of the double bevel gear shaft 325 is movably installed. The drive bevel gear 321 engages with the inner side of the support member 324. Starting the DC motor 323 drives the shaft 322, causing the switching assembly 33 to rotate. Simultaneously, the shaft 322 rotates, causing the double bevel gear shaft 325 to rotate via the drive bevel gear 321. The double bevel gear shaft 325 then drives the cleaning disc 343 to rotate via the driven bevel gear shaft 326, causing the cleaning brush 342 to clean. The cleaning assembly 34 includes a mounting base 344 fixedly installed on the right side of the inner cavity of the protective housing 311. A cleaning door 341 is movably installed on the bottom surface of the protective housing 311, and opening the cleaning door 341 allows for the removal of water and debris from inside the protective housing 311. The mounting base 344... A cleaning disc 343 is movably mounted on the left side. Several cleaning brushes 342 are fixedly mounted on the left side of the cleaning disc 343. The left end of the driven bevel gear shaft 326 movably passes through the left side of the mounting base 344 and is fixedly mounted on the right side of the cleaning disc 343. The limiting assembly 35 includes a limiting electric telescopic rod 353 fixedly mounted on the left side of the inner cavity of the protective shell 311. The extension and retraction of the limiting electric telescopic rod 353 can limit the rotation angle of the switching cylinder 338 through the three outer cylinders 3111. Three L-shaped inserts 352 are fixedly mounted on the outer side of the movable column 337, and the three L-shaped inserts 352 are evenly distributed circumferentially on the outer side of the movable column 337. Three openings are provided on the outer side of the switching cylinder 338. There are three movable slots 351, which are evenly distributed in a circle on the outside of the switching cylinder 338. Three limiting slots 354 are provided on the left side of the inner cavity of the protective shell 311, and the three limiting slots 354 are evenly distributed in a circle on the left side of the inner cavity of the protective shell 311. Three L-shaped inserts 352 are movable through the interior of the three movable slots 351 and extend to the outside of the switching cylinder 338. The left ends of the three L-shaped inserts 352 are movable through the right side of the three limiting slots 354 and extend into the interior of the three limiting slots 354. When the movable column 337 moves to the left, it can drive the three L-shaped inserts 352 to insert into the interior of the three limiting slots 354 to fix the position of the movable column 337.

[0055] The cleaning brush 342 can clean the debris on the right side of the filter screen 318 and the perforated ring plate 319. When the switching component 33 drives the filter component 31 to complete the switching, the filtered filter screen will rotate and move to the front of the cleaning disc 343. At this time, the drive component 32 is still rotating, and then drives the cleaning disc 343 to rotate and brush the debris on the right side of the filter screen 318 and the perforated ring plate 319 through the cleaning brush 342. After the cleaning is completed, the cleaning door 341 can be opened to clean out the debris inside the protective shell 311. The operation is simple and quick, which greatly improves the convenience of use and makes the cleaning work more efficient and easy.

[0056] This invention also discloses an operating method for a cutting fluid-based supply device, specifically including the following steps:

[0057] Step 1: The cutting fluid is poured into the inside of the reservoir 1 through the inlet pipe and stored properly to provide stable lubrication and cooling for subsequent machining operations;

[0058] Step 2: When the cutting fluid enters the storage tank 1, it flows into the outlet pipe 312. As the cutting fluid flows into the outlet pipe 312, it passes through the filter screen 318, which filters out iron filings and impurities. When in use, connect the equipment to power, connect the input end of the water pump to the left end of the solenoid valve pipe 313, and connect the output end to the machine tool. Then, control the solenoid valve pipe 313 to open and discharge the cutting fluid filtered by the filter screen 318 and the perforated ring plate 319. At the same time, turn on the water pump to draw out the cutting fluid for pressurization to cool the cutting tool of the machine tool. While drawing out the cutting fluid, the filter screen 318 also filters out impurities, which are carried by the water flow to the annular groove formed by the front side of the perforated ring plate 319 and the outer side of the filter screen 318 for storage. This prevents impurities from flowing back into the storage tank 1 or remaining in the outlet pipe 312, ensuring smooth and unobstructed water flow.

[0059] Step 3: When the machine tool performs rough and fine machining on different workpieces, the controller 2 controls the drive assembly 32 to start and drive the mounting cylinder 332 to rotate. When the fixed electric telescopic rod 314 is started, the filter screen 318 rises and moves towards the switching cylinder 338. The movable column 337 is adjusted to insert into the interior of the mounting cylinder 332, driving the filter screen 318 to rotate to switch between filters with different gaps to meet the machining requirements. During rotation, the limit assembly 35 can limit the rotation angle of the switching assembly 33 and separate the switching assembly 33 from the drive assembly 32 to limit and fix the switched filter screen. Before adjusting the filter screen 318 to insert into the interior of the mounting cylinder 332, the controller 2 needs to control the limit electric telescopic rod 353 to release the position restriction of the movable column 337 by the outer cylinder 3111.

[0060] Step 4: After the filter screen has been rotated and switched, the filter screen that has filtered out the debris will rotate to the front of the cleaning disc 343. At this time, the drive component 32 will drive the cleaning disc 343 to make the cleaning brush 342 remove the debris accumulated on the filter screen. Then, the cleaning door 341 can be opened to remove the debris from the equipment.

[0061] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0062] In use, the operator connects the device to power, then pours the cutting fluid into the reservoir 1 through the inlet pipe. The water pump's input is connected to the left side of the filter assembly 31, and its output is connected to the machine tool. The controller 2 then opens the solenoid valve 313, and the water pump draws the cutting fluid out through the outlet pipe 312. As the cutting fluid passes through the outlet pipe 312, it passes through the filter screen 318, which filters out impurities. These impurities accumulate and adhere to the front of the filter screen 318. When excessive impurities accumulate, the water flow carries them to the annular groove formed by the front of the perforated ring plate 319 and the outer side of the filter screen 318 for storage. When the filter screen needs to be replaced according to roughing or fine machining requirements, the controller 2 controls the opening of the solenoid valve 313. The controller 2 controls the limit electric telescopic rod 353 to retract, releasing the restriction on the outer cylinder 3111. Then, by starting the DC motor 323, the mounting cylinder 332 is rotated via the shaft 322. The L-shaped clamping plate 339 is then squeezed towards the center, pressing the retaining spring 3310 to move the right side of the L-shaped clamping plate 339 away from the left side of the switching cylinder 338. At this point, the elastic force of the first spring 3313 will push the movable column 337 to the right, placing it against the left side of the mounting cylinder 332. When the mounting cylinder 332 rotates to a certain angle, the spring pin 335 will pass through the slot 334, causing the right end of the movable column 337 to insert into the interior of the mounting cylinder 332. When the spring pin 335 moves to the right, it will be squeezed by the slot 334, causing the spring pin 335 to enter the interior of the mounting groove 336. At this point, the controller... When controller 2 extends, and spring pin 335 moves to the right into the arc groove 333, it pops out into the mounting slot 336. At this time, spring pin 335 will drive switching cylinder 338 to rotate along the trajectory of arc groove 333, causing filter assembly 31 to rotate and switch. Then, limit electric telescopic rod 353 will abut against one side of outer cylinder 3111 to restrict the position of switching cylinder 338 and prevent it from rotating. At this time, spring pin 335 will drive movable column 337 to rotate out of mounting cylinder 332. At the same time, movable column 337 will push L-shaped clamping plate 339 out of switching cylinder 338. Then, the elastic force of clamping spring 3310 can lock L-shaped clamping plate 339 into the left side of switching cylinder 338, fixing the position of movable column 337 and completing the switching. As 37 moves to the left, it causes the L-shaped insert plate 352 to insert into the limiting groove 354, and fixes the position of the switching cylinder 338 through the movable groove 351, so that the switched filter screen 318 is positioned above the groove 316. Then, the fixed electric telescopic rod 314 is activated, which drives the arc plate 317 to insert into the water outlet pipe 312 through the groove 316 to complete the replacement. At this time, the DC motor 323 is still rotating. Then, the DC motor 323 drives the active bevel gear 321 to rotate through the shaft 322. Then, the active bevel gear 321 drives the driven bevel gear shaft 326 to rotate through the double bevel gear shaft 325. At this time, the driven bevel gear shaft 326 drives the cleaning disc 343 to rotate through the cleaning brush 342 to clean the debris on the right side of the filter screen 318 and the perforated ring plate 319.After cleaning is complete, opening the cleaning door 341 will turn off the DC motor 323. Then, opening the cleaning door 341 again will allow the debris removed by the cleaning brush 342 to be removed from the inside of the protective casing 311.
