Description

Technical Field

[0001] This invention relates to the field of fragile material processing equipment, specifically a fragile material processing equipment based on the cavitation effect. Background Technology

[0002] Cavitation is the process by which vapor or gas bubbles form, develop, and collapse when the local pressure in a liquid decreases to the liquid's saturated vapor pressure. This process creates shock waves or high-speed microjets in the liquid, which impact the material surface, thus grinding the material. The effect of using cavitation to process brittle materials with low hardness is better than that of ordinary lathe grinding.

[0003] In order to speed up the processing when using cavitation effect, abrasive grains are added to the base fluid. During the processing, the abrasive grains act on the workpiece surface to accelerate the grinding speed. However, at the end of the grinding process, the abrasive grains will form deep scratches on the workpiece surface, which will reduce the flatness of the workpiece surface and reduce the processing accuracy of the workpiece surface. Summary of the Invention

[0004] The purpose of this invention is to provide a device for processing fragile materials based on the cavitation effect, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A base is fixedly connected to the bottom of the processing box, and a recovery box is located on one side of the base. The recovery box is connected to the processing box through a recovery pipe. A concentrated liquid tank and a dilute liquid tank are located between the recovery box and the base. A dilute liquid pipe is connected to the top of the recovery box and is connected to the dilute liquid tank. A concentrated liquid pipe is connected to the bottom of the recovery box and is connected to the concentrated liquid tank. A first connecting pipe is connected between the dilute liquid tank and the concentrated liquid tank. A feed pipe is connected to the middle of the first connecting pipe. One end of the feed pipe is connected to the cavitation nozzle, and a water pump is installed on the feed pipe.

[0007] Preferably, a concentrate valve is provided at the end of the first connecting pipe near the concentrate tank, and a dilute valve is provided at the end of the first connecting pipe near the dilute tank. A second connecting pipe is also provided between the concentrate tank and the dilute tank, with both ends of the second connecting pipe connected to the concentrate tank and the dilute tank respectively. A second pipe valve is installed on the second connecting pipe.

[0008] Preferably, the recovery box is equipped with a conical hopper, with multiple through holes in the middle of the conical hopper. The tip of the conical hopper faces downwards, the dilute liquid pipe is located above the conical hopper, and a guide ring is provided below the conical hopper. The outer wall of the guide ring is fixedly connected to the inner wall of the recovery box, and the recovery pipe passes into the guide ring. Multiple guide grooves are provided on the inner ring surface of the guide ring away from the recovery pipe, and a guide plate is installed on the side of the guide groove near the center of the guide ring.

[0009] Preferably, the dilute tank is equipped with a filter screen, with the first connecting pipe located above the filter screen and the second connecting pipe located below the filter screen.

[0010] Preferably, the workpiece is provided with two horizontal bars and two vertical bars around its perimeter. The horizontal bars have horizontal grooves near their two ends, and the vertical bars are located in the horizontal grooves. One of the horizontal bars has a fixed cylinder fixedly connected to one end of its side near the workpiece. The fixed cylinder has a threaded hole, and a bolt is installed in the threaded hole. One end of the bolt passes through the other horizontal bar.

[0011] Preferably, two limiting blocks are slidably connected along the length of the vertical rod on the side away from the center of the workpiece. Multiple slots are provided on the inner wall of the horizontal groove. Card strips are fixedly connected to both sides of the limiting blocks, and the card strips can be inserted into the slots.

[0012] Preferably, an installation block is provided between the two limiting blocks. The installation block is connected to the vertical rod, and a support spring is fixedly connected to both sides of the installation block. One end of the support spring is fixedly connected to the limiting block.

[0013] Preferably, a groove is provided in the middle of the base plate along the length of the crossbar, a fixed block is fixedly connected in the middle of the groove, and elastic telescopic rods are fixedly connected at both ends of the fixed block. The two elastic telescopic rods are the same size, and a slider is fixedly connected at the end of the elastic telescopic rod away from the fixed block. A fixed rod is fixedly connected to the top of the slider. A fixed hole is provided on the mounting block, and the fixed rod is inserted into the slot.

[0014] Preferably, a buffer groove is provided on the side of the horizontal bar and the vertical bar closest to the workpiece, a buffer block is provided in the buffer groove, and a buffer spring is provided on the side of the buffer block away from the workpiece. One end of the buffer spring is fixedly connected to the buffer block, and the other end is fixedly connected to the inner wall of the buffer groove.

[0015] Preferably, a motor is installed at the top of the concentrate tank, and the motor is fixedly connected to the top shell of the concentrate tank. The output shaft at the bottom of the motor passes through the top of the concentrate tank and is inserted into the concentrate tank. A stirring rod is fixedly connected to the outside of the output shaft.

[0016] The beneficial effects of this invention are:

[0017] 1. Excess base liquid in the processing tank flows into the recovery tank through the recovery pipe and settles there. Base liquid with fewer abrasive particles at the top of the recovery tank enters the desalination tank through the desalination pipe, while base liquid with more abrasive particles at the bottom of the recovery tank enters the concentration tank through the concentration pipe. Then, it is pumped away by the water pump through the first connecting pipe. The abrasive particles in the base liquid can accelerate the grinding efficiency. When the grinding work is about to be completed, the concentration valve is closed and the desalination valve is opened. The water pump sends the base liquid in the desalination tank to the cavitation nozzle. The base liquid in the desalination tank has a very low abrasive particle content, which is less likely to scratch the workpiece surface during processing. A base liquid with more abrasive particles can be used when grinding efficiency needs to be increased, and a base liquid with fewer abrasive particles can be used when precision needs to be improved, thus improving the efficiency of workpiece processing.

[0018] 2. When it is necessary to adjust the abrasive concentration in the base liquid, the second pipe valve can be opened. At this time, some base liquid with a lower abrasive concentration in the desalted liquid tank enters the concentrated liquid tank, mixing with the base liquid in the concentrated liquid tank, thus reducing the abrasive concentration in the concentrated liquid tank. This achieves the effect of adjusting the abrasive concentration in the base liquid, allowing the equipment to adapt to more working conditions. When the motor is running, it drives the stirring rod to rotate, stirring the concentrated liquid tank and making the abrasive concentration in the concentrated liquid tank more uniform, facilitating the processing of workpieces. When the base liquid in the desalted liquid tank flows away through the second connecting pipe, both the second connecting pipe and the desalted liquid pipe are at the bottom of the filter screen. At this time, the base liquid flow can clean the bottom of the filter screen, preventing the filter screen from becoming clogged after prolonged use.

[0019] 3. The limiting block is equipped with a retaining strip, and multiple retaining slots are opened on the inner side of the horizontal groove, so the retaining strip can be inserted into different slots, allowing the limiting block and vertical rod to adapt to workpieces of more sizes. Since the two horizontal rods are connected by bolts and fixing cylinders, the two horizontal rods can also adapt to workpieces of more sizes, making it very convenient to fix workpieces of different sizes.

[0020] 4. The workpiece is located between two mounting blocks. By using two elastic telescopic rods to retract and fix the slider and the fixing rod, the center of the workpiece can be located above the fixing block. This ensures that the center of the workpiece is located above the fixing block when fixing workpieces of different sizes, so as to facilitate the processing of the workpiece by the cavitation nozzle.

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0032] like Figures 1-8As shown, the present invention discloses a cavitation-based processing device for fragile materials, comprising a processing chamber 1 and a cavitation nozzle 2 installed inside the processing chamber 1. A base plate 4 is fixed to the inner wall of the bottom of the processing chamber 1, and a workpiece 3 is placed on the top of the base plate 4. A base 5 is fixedly connected to the bottom of the processing chamber 1, and a recovery chamber 6 is provided on one side of the base 5. The recovery chamber 6 is connected to the processing chamber 1 via a recovery pipe 11. A concentrated liquid tank 7 and a dilute liquid tank 8 are provided between the recovery chamber 6 and the base 5. A dilute liquid pipe 9 is connected to the top of the recovery chamber 6 and is connected to the dilute liquid tank 8. A concentrated liquid pipe 10 is connected to the bottom of the recovery chamber 6 and is connected to the concentrated liquid tank 7. A first connecting pipe 13 is connected between the dilute liquid tank 8 and the concentrated liquid tank 7. A feed pipe 12 is connected to the middle of the first connecting pipe 13. One end of the feed pipe 12 is connected to the cavitation nozzle 2, and a water pump is provided on the feed pipe 12. A base liquid with more abrasive particles can be used when grinding efficiency needs to be increased, and a base liquid with fewer abrasive particles can be used when precision needs to be improved, thereby increasing the processing efficiency of the workpiece 3.

[0033] As a technical optimization of the present invention, a concentrate valve 14 is provided at one end of the first connecting pipe 13 near the concentrate tank 7, and a dilute valve 15 is provided at the other end of the first connecting pipe 13 near the dilute tank 8. A second connecting pipe 19 is also provided between the concentrate tank 7 and the dilute tank 8. The two ends of the second connecting pipe 19 are respectively connected to the concentrate tank 7 and the dilute tank 8, and a second pipe valve 20 is installed on the second connecting pipe 19. Excess base liquid in processing tank 1 flows into recovery tank 6 through recovery pipe 11 and settles there. Base liquid with fewer abrasive particles at the top of recovery tank 6 enters dilute tank 8 through dilute pipe 9, while base liquid with more abrasive particles at the bottom of recovery tank 6 enters concentrate tank 7 through concentrate pipe 10. Then, it is pumped away by water pump through first connecting pipe 13. The abrasive particles in the base liquid can accelerate grinding efficiency. When the grinding work is about to be completed, concentrate valve 14 is closed and dilute valve 15 is opened. Water pump sends base liquid from dilute tank 8 to cavitation nozzle 2. The base liquid in dilute tank 8 has very little abrasive particle content, so it is not easy to scratch the workpiece surface during processing.

[0034] As a technical optimization of the present invention, a conical hopper 17 is provided inside the recovery box 6. Multiple through holes 18 are opened in the middle of the conical hopper 17. The tip of the conical hopper 17 faces downward. The dilute liquid pipe 9 is located above the conical hopper 17. A guide ring 22 is provided below the conical hopper 17. The outer wall of the guide ring 22 is fixedly connected to the inner wall of the recovery box 6. The recovery pipe 11 is inserted into the guide ring 22. Multiple guide grooves 23 are opened on the inner ring surface of the guide ring 22 away from the recovery pipe 11. A guide plate 24 is installed on the side of the guide groove 23 near the center of the guide ring 22. When the returned base liquid enters the guide ring 22 through the recovery pipe 11, the base liquid flows to the side of the guide ring 22 away from the recovery pipe 11, and then enters the recovery tank 6 through the guide groove 23 for sedimentation. The abrasive particles settle downwards under the action of gravity. Base liquid with more abrasive particles and base liquid with less abrasive particles can be used separately when needed. The guide plate 24 can reduce the rapid upward flow of the base liquid when entering the recovery tank 6, and the conical hopper 17 can further prevent the base liquid from flowing upwards when entering the recovery tank 6. The through hole 18 on the conical hopper 17 can allow the base liquid to pass through.

[0035] As a technical optimization of the present invention, a filter screen 21 is provided inside the desalination tank 8, with a first connecting pipe 13 located above the filter screen 21 and a second connecting pipe 19 located below the filter screen 21. The desalination pipe 9 enters the desalination tank 8 from the bottom. The first connecting pipe 13 is located above the filter screen 21. The filter screen 21 can block abrasive particles or other impurities in the base liquid, making the base liquid entering the feed pipe 12 purer, thereby increasing the machining accuracy of the part 3.

[0036] As a technical optimization of the present invention, the workpiece 3 is provided with two horizontal bars 25 and two vertical bars 26 around its perimeter. The horizontal bars 25 are provided with horizontal grooves 30 near both ends, and the vertical bars 26 are located in the horizontal grooves 30. One of the horizontal bars 25 is fixedly connected to a fixing cylinder 33 on the side of both ends near the workpiece 3. The fixing cylinder 33 is provided with a threaded hole, and a bolt 34 is provided in the threaded hole. One end of the bolt 34 passes through the other horizontal bar 25.

[0037] As a technical optimization of the present invention, two limiting blocks 28 are slidably connected along the length of the vertical rod 26 on the side away from the center of the workpiece 3. Multiple slots 31 are provided on the inner wall of the horizontal groove 30. A retaining strip 32 is fixedly connected to both sides of each limiting block 28, and the retaining strip 32 can be inserted into the slot 31. The retaining strip 32 can be inserted into different slots 31, allowing the limiting block 28 and the vertical rod 26 to accommodate workpieces 3 of various sizes. Since the two horizontal rods 25 are connected by bolts 34 and fixing cylinders 33, the two horizontal rods 25 can also accommodate workpieces 3 of various sizes, making it very convenient to fix workpieces 3 of different sizes.

[0038] As a technical optimization of the present invention, a mounting block 27 is provided between the two limiting blocks 28. The mounting block 27 is connected to the vertical rod 26, and a support spring 29 is fixedly connected to both sides of the mounting block 27. One end of the support spring 29 is fixedly connected to the limiting block 28. The support spring 29 pushes the limiting block 28 away from the mounting block 27 to fix the limiting block 28, thereby fixing the vertical rod 26 and preventing the vertical rod 26 from sliding.

[0039] As a technical optimization of the present invention, a groove 37 is provided in the middle of the base plate 4 along the length of the crossbar 25. A fixing block 38 is fixedly connected to the middle of the groove 37. Both ends of the fixing block 38 are fixedly connected to elastic telescopic rods 39. The two elastic telescopic rods 39 are the same size. A slider 40 is fixedly connected to the end of the elastic telescopic rod 39 away from the fixing block 38. A fixing rod 36 is fixedly connected to the top of the slider 40. A fixing hole 35 is provided on the mounting block 27. The fixing rod 36 is inserted into the slot. By moving the slider 40 and the fixing rod 36, the fixing rod 36 is inserted into the fixing hole 35. At this time, the elastic telescopic rod 39 tends to retract, fixing the mounting block 27, the crossbar 25, the vertical bar 26 and the workpiece 3. The workpiece 3 is located between the two mounting blocks 27. By using the retraction of the two elastic telescopic rods 39 to fix the slider 40 and the fixing rod 36, the center of the workpiece 3 can be located above the fixing block 38. When fixing workpieces 3 of different sizes, the center of the workpiece 3 is always located above the fixing block 38, so as to facilitate the processing of the workpiece 3 by the cavitation nozzle 2.

[0040] As a technical optimization of the present invention, buffer grooves are provided on the side of the horizontal bar 25 and the vertical bar 26 closest to the workpiece 3. A buffer block 41 is provided in each buffer groove, and a buffer spring 42 is provided on the side of the buffer block 41 furthest from the workpiece 3. One end of the buffer spring 42 is fixedly connected to the buffer block 41, and the other end is fixedly connected to the inner wall of the buffer groove. When the vertical bar 26 and the horizontal bar 25 contact the workpiece 3, the buffer block 41 contacts the workpiece 3 first, then compresses the buffer spring 42, buffering the pressure applied by the horizontal bar 25 and the vertical bar 26, thus preventing damage to the fragile material workpiece 3 during fixing.

[0041] As a technical optimization of the present invention, a motor 16 is provided at the top of the concentrate tank 7. The motor 16 is fixedly connected to the top shell of the concentrate tank 7. The output shaft at the bottom of the motor 16 passes through the top of the concentrate tank 7 and is inserted into the concentrate tank 7. A stirring rod is fixedly connected to the outside of the output shaft. When the motor 16 is working, it can drive the stirring rod to rotate and stir the concentrate tank 7, so that the abrasive concentration in the concentrate tank 7 is relatively uniform, which is convenient for processing the workpiece 3.

[0042] Working principle: First, fix the workpiece 3 between the two horizontal bars 25 and the two vertical bars 26. First, push the two limiting blocks 28 towards the mounting block 27, then make the two vertical bars 26 press against the workpiece 3. Next, push the limiting blocks 28 away from the mounting block 27, so that the locking strip 32 on the limiting block 28 engages with the locking groove 31, thereby restricting the workpiece 3 and preventing it from sliding along the length of the horizontal bars 25. Then, tighten the bolts 34 to tighten the two horizontal bars 25 and prevent the workpiece 3 from sliding along the vertical bars 26. The length direction is moved to fix the workpiece 3, which is convenient for processing the workpiece 3; the limiting block 28 is equipped with a retaining strip 32, and multiple retaining slots 31 are opened on the inner side of the horizontal groove 30, so the retaining strip 32 can be inserted into different retaining slots 31, so that the limiting block 28 and the vertical rod 26 can adapt to more sizes of workpiece 3. Since the two horizontal rods 25 are connected by bolts 34 and fixing cylinders 33, the two horizontal rods 25 can also adapt to more sizes of workpiece 3, which is very convenient when fixing workpieces 3 of different sizes.

[0043] The support spring 29 pushes the limiting block 28 away from the mounting block 27 to fix the limiting block 28, thereby fixing the vertical rod 26 and preventing the vertical rod 26 from sliding.

[0044] When the vertical bar 26 and the horizontal bar 25 come into contact with the workpiece 3, the buffer block 41 first contacts the workpiece 3, and then compresses the buffer spring 42 to buffer the pressure applied to the horizontal bar 25 and the vertical bar 26, so as to avoid damage to the fragile material workpiece 3 when it is fixed.

[0045] The positions of the slider 40 and the fixing rod 36 are moved so that the fixing rod 36 is inserted into the fixing hole 35. At this time, the elastic telescopic rod 39 tends to retract, fixing the mounting block 27, the horizontal bar 25, the vertical bar 26 and the workpiece 3. The workpiece 3 is located between the two mounting blocks 27. By using the retraction of the two elastic telescopic rods 39 to fix the slider 40 and the fixing rod 36, the center of the workpiece 3 can be located above the fixing block 38. When fixing workpieces 3 of different sizes, the center of the workpiece 3 is always located above the fixing block 38, so as to facilitate the processing of the workpiece 3 by the cavitation nozzle 2.

[0046] After the fixation is completed, the water pump starts working. At this time, the desalination valve 15 and the second pipe valve 20 are closed, and the concentrate valve 14 is open. The water pump delivers the base liquid in the concentrate tank 7 to the cavitation nozzle 2 through the feed pipe 12 and the first connecting pipe 13. The base liquid is sprayed out from the cavitation nozzle 2 to process the workpiece 3. The excess base liquid in the processing tank 1 will flow into the recovery tank 6 through the recovery pipe 11 and settle in the recovery tank 6. The base liquid with fewer abrasive particles at the upper end of the recovery tank 6 enters the desalination tank 8 through the desalination pipe 9. The base liquid with more abrasive particles at the bottom of the recovery tank 6 enters the concentrate tank 7 through the concentrate pipe 10 and is then pumped away by the water pump through the first connecting pipe 13. The abrasive particles in the base liquid can accelerate the grinding efficiency.

[0047] When the grinding work is about to be completed, the concentrated liquid valve 14 is closed and the dilute liquid valve 15 is opened. The water pump sends the base liquid in the dilute liquid tank 8 to the cavitation nozzle 2. The base liquid in the dilute liquid tank 8 has a very low abrasive content, so it is not easy to scratch the surface of the workpiece during processing. A base liquid with more abrasive particles can be used when it is necessary to increase the grinding efficiency, and a base liquid with fewer abrasive particles can be used when it is necessary to improve the precision, thereby improving the processing efficiency of the workpiece 3.

[0048] When it is necessary to adjust the abrasive concentration in the base liquid, the second valve 20 can be opened. At this time, some base liquid with a lower abrasive concentration in the dilute tank 8 enters the concentrate tank 7 and mixes with the base liquid in the concentrate tank 7, reducing the abrasive concentration in the concentrate tank 7. This achieves the effect of adjusting the abrasive concentration in the base liquid, allowing the equipment to adapt to more working conditions. When the motor 16 is working, it can drive the stirring rod to rotate, stirring the concentrate tank 7 to make the abrasive concentration in the concentrate tank 7 more uniform, which is convenient for processing the workpiece 3. When the base liquid in the dilute tank 8 flows away through the second connecting pipe 19, both the second connecting pipe 19 and the dilute pipe 9 are at the bottom of the filter screen 21. At this time, the base liquid flow can clean the bottom of the filter screen 21, preventing the filter screen 21 from becoming clogged after long-term use.

[0049] The desalination tank 8 is equipped with a filter screen 21. The desalination pipe 9 enters the desalination tank 8 from the bottom. The first connecting pipe 13 is located above the filter screen 21. The filter screen 21 can block abrasive particles or other impurities in the base liquid, making the base liquid entering the feed pipe 12 purer, thereby increasing the machining accuracy of the part 3.

[0050] The recovery tank 6 is equipped with a conical hopper 17 and a guide ring 22. When the returning base liquid enters the guide ring 22 through the recovery pipe 11, the base liquid flows to the side of the guide ring 22 away from the recovery pipe 11, and then enters the recovery tank 6 through the guide groove 23 for sedimentation. The abrasive particles settle downwards under the action of gravity. Base liquids with more abrasive particles and base liquids with fewer abrasive particles can be used separately when needed. The guide plate 24 can reduce the rapid upward flow of the base liquid when entering the recovery tank 6, and the conical hopper 17 can further prevent the base liquid from flowing upwards when entering the recovery tank 6.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
