Description

Technical Field

[0001] This invention belongs to the field of machining cooling technology, and particularly relates to a machining coolant atomization device with uniform mist output. Background Technology

[0002] When machining parts, coolant must be sprayed onto the machined surface to reduce the temperature of the cutting area, thereby reducing heat accumulation, avoiding part deformation and tool wear caused by high temperature, and ensuring machining accuracy. Compared with dry cutting, micro-lubrication machining uses an oil mist mixture, which improves the lubrication and cooling effect during the cutting process, reduces the amount of cutting fluid used, and reduces environmental pollution.

[0003] Chinese Patent Publication No. CN113977344B discloses an ultrasonic vibration atomizing rotary jet cooling device and its operating process. The device includes an ultrasonic vibration atomizing system, a vapor-mist mixing chamber, a high-pressure air intake unit, and a nozzle unit. The curved vibration atomizing disc of the ultrasonic vibration atomizing system is installed at the antinode of the vibration transmission rod, and the curved vibration atomizing disc is sleeved on the vibration transmission rod. The high-pressure air intake unit and the nozzle unit are arranged opposite to each other on the side of the vapor-mist mixing chamber. When the ultrasonic power supply is turned on, it outputs a high-frequency oscillating electrical signal. The piezoelectric ceramic transducer receives the electrical signal and converts it into mechanical vibration. The longitudinal vibration amplitude rod amplifies the vibration and transmits it to the bending vibration atomizing disc through the vibration transmission rod. At the same time, the coolant flows from the amplitude rod inlet to the antinode of the bending vibration atomizing disc, forming atomized droplets under the action of bending vibration. The high-pressure gas blown in by the high-pressure air intake unit drives the atomized droplets to be sprayed from the nozzle unit into the cutting area in a rotating jet manner. In practical applications, due to the constantly changing shape and position of the cutting surface, the spraying equipment cannot fully spray and wet the cutting surface when dealing with irregularly shaped machining surfaces, making it difficult to meet the needs of cutting processing. This undoubtedly exposes the shortcomings of the existing technology. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that spray equipment cannot fully spray and wet the machined surface when dealing with irregularly shaped machined surfaces, thus failing to meet the cutting requirements, and to propose a machining coolant atomization device with uniform mist output.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A machining coolant atomizing device with uniform mist output includes a base, an inner cavity of the base, a spray adjustment mechanism on the front side of the cavity, a liquid distribution plate on the other side of the cavity, and a mixing mechanism connected to the side of the liquid distribution plate near the spray adjustment mechanism. The base is externally connected to a drive control mechanism, which is connected to a liquid spraying adjustment mechanism. The drive control mechanism controls the spraying direction of the liquid spraying adjustment mechanism. Multiple pressurizing mechanisms are equidistantly connected around the outer periphery of the base along the axis. The bottom side of each pressurizing mechanism is connected to one side of the mixing mechanism.

[0006] As a further description of the above technical solution: The liquid spraying adjustment mechanism includes a liquid spraying ring, with an inlet sleeve connected to the bottom of the liquid spraying ring. The inlet sleeve is connected to one side of the mixing mechanism. A liquid spraying end ring is connected to the front side of the inner cavity of the liquid spraying ring. Multiple first nozzles are provided around the inner cavity of the liquid spraying end ring. Multiple second nozzles are equidistantly connected around the inner cavity of the liquid spraying ring along the axis. The inner cavity of the liquid spraying ring is rotatably connected to the inlet sleeve. Multiple through slots are equidistantly opened around the inner cavity of the inlet sleeve along the axis. Multiple guide cavities are equidistantly opened around the outer side of the inlet sleeve along the axis. The inner cavity of the guide cavity is connected to an injection pipe, which extends to the top and is connected to the first nozzles. The rotation of the guide ring controls the connection between the second nozzles and the through slots or guide cavities.

[0007] As a further description of the above technical solution: The first nozzle is set at an angle inclined towards the axis, and the plurality of first nozzles are offset in a spiral shape.

[0008] As a further description of the above technical solution: The guide ring is connected to an external drive control mechanism, which includes a rotating ring connected to the outside of the spray ring. A moving block is connected to the outside of the rotating ring. A connecting rod is rotatably connected to one side of the moving block, and a rotating block is hinged to the other end of the connecting rod. An electric push rod is connected to one side of the rotating block, and a fixed block is connected to the other end of the electric push rod. A support block is rotatably connected to one side of the fixed block, and the support block is connected to the outside of the base at the corresponding position.

[0009] As a further description of the above technical solution: The pressurizing mechanism includes a pressurizing pipe, the top of which is connected to a connecting valve, which extends to the outside of the base through a through hole on the outside of the base. The other ends of the multiple pressurizing pipes are connected to a mixing tank through pressurizing ports. The side of the mixing tank near the spray ring is connected to the inlet sleeve, and the side of the mixing tank away from the inlet sleeve is connected to the distribution plate. The mixing tank is supplied with pressurized cooling medium sequentially through multiple pressurizing pipes on its periphery.

[0010] As a further description of the above technical solution: The mixing tank has multiple chambers for mixing coolant on one side, and an inlet is provided on the outside of the mixing tank corresponding to the position of the chamber. The inlet is located in the inner cavity of the distributor plate, and guide plates are connected to both sides of the inner cavity of the chamber. The inclined surfaces of the guide plates on both sides are close to each other to guide the coolant to overflow to the overflow port at the bottom of the chamber. A baffle rod is rotatably connected to one side of the inner cavity of the chamber through a bearing.

[0011] As a further description of the above technical solution: Both ends of one side of the liquid separator are connected to a medium pipe, and the medium pipe is connected to an external pressure pump.

[0012] As a further description of the above technical solution: The inner cavity of the pressurization tube is provided with multiple circumferentially arranged drainage rings to guide the medium to flow in a spiral shape.

[0013] As a further description of the above technical solution: The base has a groove on its side wall, and a heat spreader is connected inside the groove. The heat spreader is sleeved outside the pressure pipe at the corresponding position to prevent the medium from overheating.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, through the designed spray adjustment mechanism, the inlet sleeve can uniformly deliver coolant into the second nozzle. When the second nozzle is connected to the through groove, the coolant spray can be guided into the guide ring through the through groove. When the coolant is sprayed into the inner side of the guide ring, it can spray coolant onto the inner cutting head and cutting position. Through multiple sets of second nozzles on the periphery, the cutting position can be fully atomized and cooled. The spray ring is controlled to rotate by the drive control mechanism. When the spray ring rotates, the inner second nozzle can contact the outer guide cavity of the guide ring. At this time, the coolant sprayed from the second nozzle can be sent into the rear first nozzle through the pipe on the back side of the guide cavity. After multiple first nozzles spray coolant, the coolant can spray outward at an inclined angle to spray and cool the cutting surface on the outside. The spray angle of the coolant is adjusted by the rotation of the guide ring. Through the adjustable spray cooling, the adaptability of the cooling spray to different irregular surfaces is improved, and the machining stability is ensured.

[0015] 2. In this invention, the designed drive control mechanism uses an electric push rod to extend and move the front rotating block. The movement of the rotating block moves the connecting rod, and the other end of the connecting rod moves the moving block. The movement of the moving block moves the rotating ring outside the base. The rotation of the rotating ring moves the inner spray ring. The rotation of the spray ring moves the inner second nozzle to adjust its relative position outside the guide ring. The spray angle of the coolant can be adjusted and controlled by the electric push rod to adapt to the spray cooling of different machined surfaces. The coolant sprayed from multiple first nozzles on the periphery can fully wet the irregularly shaped machined surface, improving the processing stability.

[0016] 3. In this invention, multiple pressurizing mechanisms arranged around the periphery allow pressurized gas or pressurized cooling medium to be sequentially pumped into the pressurizing pipe via an external pumping device. The coolant entering the pressurizing pipe is guided by a guide ring to generate a spiral vortex and is mixed after entering the mixing mechanism. Furthermore, through a designed connecting valve, the coolant can enter the pressurizing pipe after being pressurized and pumped in by the external pressurizing device, preventing backflow of the pressurized coolant from affecting the pumping effect. The medium liquid can be fully mixed with the other medium entering through the distribution plate and the medium pipe in the mixing tank chamber. The mixed medium liquid can enter the second nozzle on the front side through a pipe, which is beneficial for achieving compound mixing of the coolant by mixing media from different directions, thereby improving the mixing efficiency.

[0019] 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.

[0020] Please see Figures 1-11 The present invention provides a technical solution: a machining coolant atomizing device with uniform mist output, including a base 1, a cavity inside the base 1, a liquid spraying adjustment mechanism 2 provided on the front side of the cavity, a liquid distribution plate 7 provided on the other side of the cavity, and a mixing mechanism 6 connected to the side of the liquid distribution plate 7 near the liquid spraying adjustment mechanism 2. The base 1 is externally connected to a drive control mechanism 3, which is connected to a spray adjustment mechanism 2. The drive control mechanism 3 controls the spray direction of the spray adjustment mechanism 2. Multiple pressurizing mechanisms 4 are equidistantly connected around the outer periphery of the base 1 along the axis. The bottom side of the pressurizing mechanism 4 is connected to one side of the mixing mechanism 6. The spray adjustment mechanism 2 includes a spray ring 201. A liquid inlet sleeve 205 is connected to the bottom of the spray ring 201. The liquid inlet sleeve 205 is connected to one side of the mixing mechanism 6. A spray end ring 202 is connected to the front side of the inner cavity of the spray ring 201. Multiple first nozzles 203 are provided around the inner periphery of the spray end ring 202. Multiple second nozzles 204 are equidistantly arranged around the inner cavity of the spray ring 201 along its axis. The inner cavity of the spray ring 201 is rotatably connected to the liquid inlet sleeve 205. The inner cavity of the liquid inlet sleeve 205... Multiple through slots 207 are equidistantly arranged around the axis. Multiple guide cavities 208 are equidistantly arranged on the outside of the liquid inlet sleeve 205 along the axis. The inner cavity of the guide cavity 208 is connected to the liquid injection pipe, and the liquid injection pipe extends to the top and connects to the first nozzle 203. The rotation of the guide ring 206 controls the second nozzle 204 to connect with the through slots 207 or guide cavities 208. The first nozzle 203 is set at an angle inclined towards the axis, and the multiple first nozzles 203 are offset in a spiral shape.

[0021] Specifically: In this embodiment, the base 1 should be located on the outer periphery of the tool or the fixture side of the machining platform. Through the designed spray adjustment mechanism 2, when the coolant injected from the bottom via the pressurization mechanism 4 and the distribution plate 7 is fully mixed by the mixing mechanism 6, the mixed coolant can be sent into the inlet sleeve 205. The inlet sleeve 205 can evenly deliver the coolant into the second nozzle 204. When the second nozzle 204 is connected to the through groove 207, the coolant sprayed out can be guided through the through groove 207 into the guide ring 206. When the coolant is sprayed into the inner side of the guide ring 206, it can spray coolant onto the tool head and cutting position inside. Multiple sets of second nozzles 204 on the periphery... 4. It can provide sufficient atomized cooling to the cutting position. When the cutting position is large and exceeds the inner diameter of the guide ring 206, the spray ring 201 can be rotated by the drive control mechanism 3. The inner second nozzle 204 of the spray ring 201 can contact the outer guide cavity 208 of the guide ring 206. At this time, the coolant sprayed by the second nozzle 204 can be sent into the rear first nozzle 203 through the rear pipe of the guide cavity 208. After multiple first nozzles 203 spray coolant, the coolant can spray outward at an inclined angle to spray and cool the cutting surface on the outside. Thus, the spray angle of the coolant can be adjusted by rotating the guide ring 206.

[0022] Please see Figure 3 and Figures 10-11The guide ring 206 is connected to the external drive control mechanism 3. The drive control mechanism 3 includes a rotating ring 301, which is connected to the outside of the spray ring 201. A moving block 302 is connected to the outside of the rotating ring 301. A connecting rod 303 is rotatably connected to one side of the moving block 302, and a rotating block 304 is hinged to the other end of the connecting rod 303. An electric push rod 305 is connected to one side of the rotating block 304, and a fixed block 306 is connected to the other end of the electric push rod 305. A support block 307 is rotatably connected to one side of the fixed block 306, and the support block 307 is connected to the outside of the base 1 at the corresponding position.

[0023] Specifically: Through the designed drive control mechanism 3, the electric push rod 305 extends to drive the front rotating block 304 to move. The movement of the rotating block 304 can drive the connecting rod 303 to move. The other end of the connecting rod 303 can drive the moving block 302 to move. The movement of the moving block 302 can drive the rotating ring 301 to rotate outside the base 1. The rotation of the rotating ring 301 can drive the inner spray ring 201 to rotate. The rotation of the spray ring 201 can drive the inner second nozzle 204 to adjust its relative position outside the guide ring 206. Thus, the spray angle of the coolant can be adjusted and controlled by the electric push rod 305 to adapt to the spray cooling of different processing surfaces. Furthermore, the coolant sprayed from the multiple first nozzles 203 on the periphery can fully wet the irregular processing surface and improve processing stability.

[0024] Please see Figures 3-5 and Figure 8 The pressurizing mechanism 4 includes a pressurizing pipe 401. A connecting valve 403 is connected to the top of the pressurizing pipe 401, and the connecting valve 403 extends to the outside of the base 1 through a through hole on the outside of the base 1. The other ends of the multiple pressurizing pipes 401 are connected to a mixing tank 604 through a pressurizing port 605. The side of the mixing tank 604 near the spray ring 201 is connected to the inlet sleeve 205, and the end of the mixing tank 604 away from the inlet sleeve 205 is connected to the liquid distribution plate 7. The mixing tank 604 is sequentially fed with pressurized cooling medium through multiple pressurizing pipes 401 on its periphery. Furthermore, through the designed pressurizing mechanism 4, and through multiple pressurizing mechanisms 4 arranged around the periphery, pressurized gas or pressurized cooling medium can be sequentially sent into the pressurizing pipe 401 by external pumping equipment. The coolant entering the pressurizing pipe 401 can generate a spiral vortex through the guidance of the guide ring 402 and be mixed after entering the mixing mechanism 6. Furthermore, through the designed connecting valve 403, after being pressurized and pumped in by external pressurizing equipment, it can enter the pressurizing pipe 401 through the connecting valve 403, avoiding the backflow of pressurized coolant and affecting the pumping effect. Please see Figures 6-8The mixing tank 604 has multiple chambers for mixing coolant on one side, and an inlet 603 is provided on the outside of the mixing tank 604 corresponding to the position of the chamber. The inlet 603 is located in the inner cavity of the distributor plate 7, and guide plates 601 are connected to both sides of the inner cavity. The inclined surfaces of the guide plates 601 on both sides are close to each other to guide the coolant to overflow to the overflow port at the bottom of the chamber. A baffle rod 602 is rotatably connected to one side of the inner cavity of the chamber through a bearing. Medium pipes 5 are connected to both ends of one side of the distributor plate 7, and the medium pipes 5 are connected to an external pressure pump. The inner cavity of the pressure pipe 401 is provided with multiple circumferentially arranged guide rings 402 to guide the medium to flow in a spiral shape.

[0025] Specifically: Through the designed mixing tank 604, when the pressurized medium pumped in by the pressurizing mechanism 4 enters the mixing tank 604, the guide plates 601 on both sides of the inner cavity of the mixing tank 604 guide the incoming medium liquid, and the medium liquid can be fully mixed with the other medium entering through the distribution plate 7 and the medium pipe 5 in the mixing tank 604 cavity. The mixed medium liquid can enter the front second nozzle 204 through the pipe, which is conducive to the compound mixing of coolant by mixing media from different directions, improving the mixing efficiency. Furthermore, the media on both sides entering the mixing tank 604 cavity are in a vertical state and can be fully mixed by the turbulence bar 602. The turbulence bar 602 has spiral blades on the outside, so that the cooling medium or pressurized medium on both sides can be fully mixed in a vortex state, thereby further improving the mixing effect.

[0026] The base 1 has a groove on its side wall, and a heat spreader 8 is connected in the groove. The heat spreader 8 is sleeved on the outside of the pressure pipe 401 at the corresponding position to prevent the medium from overheating.

[0027] Working principle: During use, when the coolant injected from the bottom through the pressurizing mechanism 4 and the distributing plate 7 is fully mixed by the mixing mechanism 6, the mixed coolant is sent into the inlet sleeve 205. The inlet sleeve 205 evenly delivers the coolant into the second nozzle 204. When the second nozzle 204 is connected to the through groove 207, the coolant is sprayed out and guided through the through groove 207 into the guide ring 206. When the coolant is sprayed into the inner side of the guide ring 206, it sprays coolant onto the cutting head and cutting position inside. This is achieved through multiple sets of second nozzles 204 around the perimeter. Sufficient atomized cooling is applied to the cutting position. When the cutting position is large and exceeds the inner diameter of the guide ring 206, the spray ring 201 is rotated by the drive control mechanism 3. The inner second nozzle 204 of the spray ring 201 contacts the outer guide cavity 208 of the guide ring 206. At this time, the coolant sprayed from the second nozzle 204 is sent into the rear first nozzle 203 through the rear pipe of the guide cavity 208. After multiple first nozzles 203 spray coolant, the coolant is sprayed outward at an inclined angle to spray and cool the cutting surface on the outer side. The electric push rod 305 extends to move the front rotating block 304. The movement of the rotating block 304 moves the connecting rod 303. The other end of the connecting rod 303 moves the moving block 302. The movement of the moving block 302 moves the rotating ring 301 outside the base 1. The rotation of the rotating ring 301 moves the inner spray ring 201. The rotation of the spray ring 201 moves the inner second nozzle 204 to adjust its relative position outside the guide ring 206. The spray angle of the coolant is adjusted and controlled by the electric push rod 305. Multiple pressurizing mechanisms 4 are arranged around the perimeter, and pressurized gas or pressurized cooling medium is sequentially pumped into the pressurizing pipe 401 by external pumping equipment. The coolant entering the pressurizing pipe 401 is guided by the guide ring 402 to generate a spiral vortex and is mixed after entering the mixing mechanism 6. When the pressurized medium pumped in from the pressurizing mechanism 4 enters the mixing tank 604, the guide plates 601 on both sides of the inner cavity of the mixing tank 604 guide the entering medium liquid. The medium liquid is fully mixed with the other medium entering from the distribution plate 7 and the medium pipe 5 in the mixing tank 604. The mixed medium liquid enters the front second nozzle 204 through the pipeline. By mixing the medium from different directions, the coolant is compounded and mixed.
