Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial equipment, in particular to a nozzle device and a flushing device. BACKGROUND

[0002] Nozzles have a wide range of applications in the industrial field. For example, a flushing device of a machining center needs to use a nozzle. A liquid pump sucks cutting fluid in a liquid tank into a liquid delivery pipe, and then the cutting fluid is sprayed out through the nozzle to flush the machining tool and workpiece of the machining center.

[0003] However, the current common flushing device has a problem in use: when the liquid pump stops working, the cutting fluid in the part of the liquid delivery pipe between the liquid pump and the nozzle will flow out through the nozzle, so the nozzle cannot immediately stop discharging liquid, that is, after the liquid pump stops working, the nozzle will still continue to discharge a certain amount of cutting fluid. When the machining center is working, the staff pauses the liquid discharge to perform a tool changing operation, and the continuously dripping cutting fluid will pollute the precision components such as tool shanks and tool setting devices in the tool magazine area, thereby affecting the accuracy of related equipment. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a nozzle device, and further provides a flushing device.

[0005] In a first aspect, the present application provides a nozzle device, which comprises a nozzle body, a partition plate and a liquid stopping assembly. The nozzle body is provided with a liquid delivery hole, which is a through hole and is provided with an inlet end and an outlet end. The partition plate is arranged in the liquid delivery hole and is provided with a communication port communicating with the liquid delivery hole. The liquid stopping assembly is arranged in the liquid delivery hole. The liquid stopping assembly comprises a pressure adjusting mounting piece, a reset elastic piece and a bearing piece. The pressure adjusting mounting piece is arranged on one side of the partition plate facing the outlet end. At least part of the structure of the bearing piece is located between the pressure adjusting mounting piece and the partition plate. One end of the reset elastic piece abuts against the pressure adjusting mounting piece, and the other end abuts against the bearing piece. The bearing piece is abutted by the reset elastic piece against the partition plate to block the communication port. The pressure adjusting mounting piece can move along the hole axis direction of the liquid delivery hole to change the distance between itself and the partition plate, so as to change the abutting force of the reset elastic piece on the bearing piece.

[0006] Optionally, in some embodiments, the liquid delivery hole comprises a first hole section and a second hole section arranged coaxially and connected in sequence. The partition plate is arranged between the first hole section and the second hole section. The communication port communicates the first hole section and the second hole section. The liquid stopping assembly is arranged in the second hole section. The second hole section is provided with a first internal thread. The pressure adjusting mounting piece is provided with an external thread. The pressure adjusting mounting piece and the second hole section are threadedly connected through the first internal thread and the external thread.

[0007] Optionally, in some embodiments, the abutting member comprises an abutting head and a connecting rod, one end of the connecting rod is connected to the abutting head, the connecting rod is movably arranged in the pressure regulating mount along the axial direction of the infusion hole, one end of the reset elastic member is abutted to the pressure regulating mount, and the other end is abutted to the abutting head, so that the abutting head seals the communication port.

[0008] Optionally, in some embodiments, the reset elastic member is a spring, and the reset elastic member is sleeved on the connecting rod and is in contact with the side wall of the connecting rod.

[0009] Optionally, in some embodiments, the diameter of the abutting head gradually increases from the end away from the connecting rod to the end close to the connecting rod, the minimum diameter of the abutting head is smaller than the diameter of the communication port, and the maximum diameter of the abutting head is greater than the diameter of the communication port.

[0010] Optionally, in some embodiments, at least part of the structure of the pressure regulating mount is arranged to be spaced from the inner side wall of the second hole section to form the liquid passing port.

[0011] In a second aspect, the embodiments of the present application also provide a flushing device, which comprises a flushing assembly; the flushing assembly comprises a liquid storage tank, an infusion pipe, a liquid pump and the nozzle device. One end of the infusion pipe is in communication with the liquid storage tank. The liquid pump is connected between the infusion pipe and the liquid storage tank. The liquid inlet end of the nozzle device is connected to the infusion pipe.

[0012] Optionally, in some embodiments, the flushing device comprises two flushing assemblies, the liquid outlet end of the nozzle device of one of the flushing assemblies is directed to the machining tool of the machining center, and the liquid outlet end of the nozzle device of the other flushing assembly is directed to the chip groove of the machining center.

[0013] Optionally, in some embodiments, the flushing assembly further comprises a handheld spray gun, and the handheld spray gun is in communication with the infusion pipe.

[0014] Optionally, in some embodiments, the nozzle device in the flushing assembly is provided in plurality, the liquid inlet end of each of the plurality of nozzle devices is in communication with the infusion pipe, and the liquid spraying directions of the plurality of nozzle devices are different.

[0015] In the nozzle device provided in the embodiment of the present application, the nozzle device includes a nozzle body, a partition plate and a liquid-stopping assembly. The nozzle body is provided with an infusion hole, the partition plate is provided in the infusion hole, and the partition plate is provided with a connecting port. The liquid-stopping assembly includes a pressure-regulating mounting member, a reset elastic member and a supporting member. The pressure-regulating mounting member is provided on the side of the partition plate facing the liquid outlet end, and at least part of the structure of the supporting member is located between the pressure-regulating mounting member and the partition plate. One end of the reset elastic member abuts against the regulating mounting member, and the other end abuts against the supporting member. The supporting member is abutted against the partition plate by the reset elastic member to block the connecting port. Through the above arrangement, when the nozzle device is connected to the infusion tube of the flushing device for use, when the liquid pump is started, the liquid will enter the infusion hole along the infusion tube. Under the action of the liquid pressure, the supporting member will move in the direction away from the partition plate, thereby making the connecting port conductive. At this time, the liquid can smoothly pass through the infusion hole and be sprayed out from the liquid outlet end of the nozzle body. When the liquid pump stops, the retaining element loses its impact with the liquid and, under the action of the reset elastic element, it re-engages with the partition plate to seal the communication port, thereby preventing any liquid remaining between the liquid pump and the partition plate from continuing to flow out of the nozzle body. This prevents continued dripping of liquid from contaminating precision components such as the tool holder and tool setter within the tool magazine when the operator pauses to change tools during machining, thereby preventing the accuracy of related equipment from being affected.

[0016] Furthermore, since the pressure regulating mounting member can move along the axial direction of the infusion hole, the minimum pressure value allowing the communication port to be opened can be changed by changing the relative position of the pressure regulating mounting member and the partition plate, thereby meeting more diverse production needs.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 The embodiments of the present application provide a nozzle device 100, which is applied to any liquid spraying system. Specifically, the nozzle device 100 is arranged at the liquid spraying end of the liquid spraying system. The power member (such as a liquid pump 213) of the liquid spraying system delivers the liquid to be sprayed into the nozzle device 100, and then the liquid is sprayed out through the nozzle device 100 to meet the liquid spraying requirement. The liquid spraying system can be a flushing device, a flushing system, or a spraying system of a machining machine tool, or a cleaning flushing system for cleaning general environment, or a spraying system or a flushing system for gardening work.

[0031] The nozzle device 100 includes a nozzle body 11, a partition plate 12, and a liquid stopping assembly 13.

[0032] The nozzle body 11 is a main structure of the nozzle device 100, and is generally in a columnar shape. The nozzle body 11 is provided with a liquid delivery hole 111, which is a passage for liquid to flow through the nozzle body 11. The liquid delivery hole 111 is a through hole, and liquid flows into the liquid delivery hole 111 from a liquid inlet end 112 and flows out of the liquid delivery hole 111 from a liquid outlet end 113.

[0033] The partition plate 12 is arranged in the liquid delivery hole 111, and is used to divide the liquid delivery hole 111 into two parts. The partition plate 12 is provided with a communication hole 121 that communicates with the liquid delivery hole 111. The communication hole 121 communicates the two parts of the liquid delivery hole 111 on both sides of the partition plate 12, so that liquid in the liquid delivery hole 111 can pass through the partition plate 12 through the communication hole 121.

[0034] The liquid stopping assembly 13 is arranged in the liquid delivery hole 111, and is used to immediately interrupt the liquid delivery hole 111 when the power member of the liquid spraying system is turned off, so as to avoid continuous liquid delivery. The liquid stopping assembly 13 includes a pressure regulating mounting member 131, a reset elastic member 132, and a bearing member 133. The pressure regulating mounting member 131 is arranged on the side of the partition plate 12 facing the liquid outlet end 113. At least part of the structure of the bearing member 133 is located between the pressure regulating mounting member 131 and the partition plate 12. One end of the reset elastic member 132 abuts against the pressure regulating mounting member, and the other end abuts against the bearing member 133. The bearing member 133 is abutted by the reset elastic member 132 against the partition plate 12 to block the communication hole 121. The pressure regulating mounting member 131 can move along the hole axis direction of the liquid delivery hole 111 to change the distance between itself and the partition plate 12, so as to change the abutting force of the reset elastic member 132 on the bearing member 133.

[0035] Through the above arrangement, in use, the liquid entering the liquid inlet hole 111 will generate an impact force on the abutting piece 133 in the direction of the liquid outlet end 113. If the impact force is less than the elastic force of the reset elastic piece 132 acting on the abutting piece 133 (i.e. the abutting force of the reset elastic piece 132 on the abutting piece 133), the abutting piece 133 will remain in contact with the partition plate 12, thereby blocking the communication port 121 to prevent liquid from flowing out of the liquid outlet end 113; if the impact force is greater than the elastic force of the reset elastic piece 132 acting on the abutting piece 133 (i.e. the abutting force of the reset elastic piece 132 on the abutting piece 133), the abutting piece 133 will move in the direction of the liquid outlet end 113, thereby separating from the partition plate 12. At this time, the abutting piece 133 loses the blocking effect on the communication port 121, and the liquid can pass through the communication port 121 and eventually flow out of the liquid outlet end 113 of the nozzle body 11. Therefore, when the power piece of the liquid spraying system is turned on, the abutting piece 133 is separated from the partition plate 12 by the impact of the liquid, at which time the liquid can be sprayed out of the liquid outlet end 113 of the liquid inlet hole 111 through the communication port 121; when the power piece of the liquid spraying system is turned off, the liquid loses driving force, so under the action of the reset elastic piece 132, the abutting piece 133 re-abuts on the partition plate 12 to block the communication port 121, at which time the liquid remaining in the pipeline between the nozzle device 100 and the power piece cannot continue to flow out through the nozzle device 100, so the quick shutdown of the nozzle device 100 can be realized, avoiding the situation that the nozzle device 100 continues to drip after the power piece is turned off. In this way, when the operator pauses the liquid spraying to perform the tool changing operation during the machining process of the machining center, the liquid dripping from the nozzle can be prevented from contaminating the precision components such as the tool shank and the tool setting instrument in the internal area of the tool magazine, thereby avoiding affecting the precision of the related equipment.

[0036] Moreover, since the position of the pressure regulating mounting piece 131 in the liquid inlet hole 111 can be adjusted, the spacing between the pressure regulating mounting piece 131 and the partition plate 12 can be adjusted, the compression degree of the reset elastic piece 132 can be changed, and thus the size of the elastic force of the reset elastic piece 132 acting on the abutting piece 133 (i.e. the abutting force of the reset elastic piece 132 on the abutting piece 133) can be changed, i.e. the minimum pressure value required to open the communication port 121 can be changed. Specifically, the smaller the spacing between the pressure regulating mounting piece 131 and the partition plate 12, the greater the minimum pressure value required to open the communication port 121. Therefore, the above nozzle device 100 can meet various use requirements and has a wider application space.

[0037] In some embodiments, the infusion hole 111 comprises a first hole segment 1111 and a second hole segment 1112 coaxially arranged and connected in sequence. The partition plate 12 is arranged between the first hole segment 1111 and the second hole segment 1112, the communication port 121 communicates the first hole segment 1111 and the second hole segment 1112, and the liquid stopping assembly 13 is arranged in the second hole segment 1112. The end of the first hole segment 1111 away from the second hole segment 1112 is the liquid inlet end 112 of the infusion hole 111, and the end of the second hole segment 1112 away from the first hole segment 1111 is the liquid outlet end 113 of the infusion hole 111. The second hole segment 1112 is provided with a first internal thread, the pressure regulating mounting 131 is provided with an external thread, and the pressure regulating mounting 131 and the second hole segment 1112 are threadedly connected through the first internal thread and the external thread.

[0038] Through the above arrangement, since the pressure regulating mounting 131 is threadedly connected with the second hole segment 1112, rotating the pressure regulating mounting 131 can change the position of the pressure regulating mounting 131 in the infusion hole 111, so as to change the distance between the pressure regulating mounting 131 and the partition plate 12, that is, to change the minimum pressure value required to open the communication port 121. Therefore, the position adjustment operation of the pressure regulating mounting 131 is simple and convenient.

[0039] In some embodiments, the abutting piece 133 comprises an abutting head 1331 and a connecting rod 1332. The abutting head 1331 is block-shaped, and is the main structure of the abutting piece 133 for plugging the communication port 121. The connecting rod 1332 is rod-shaped, and is mainly used to realize the connecting and mounting of the abutting piece 133 and the pressure regulating mounting 131. One end of the connecting rod 1332 is connected to the abutting head 1331, and the connecting rod 1332 is movably arranged in the pressure regulating mounting 131 along the axial direction of the infusion hole 111. One end of the reset elastic piece 132 abuts against the pressure regulating mounting 131, and the other end abuts against the abutting head 1331, so that the abutting head 1331 plugs the communication port 121.

[0040] Through the above arrangement, since one end of the reset elastic piece 132 abuts against the pressure regulating mounting 131, and the other end abuts against the abutting head 1331, and the position of the pressure regulating mounting 131 is fixed at a certain moment, the elastic force of the reset elastic piece 132 will abut the abutting head 1331 against the surface of the partition plate 12, so as to plug the communication port 121. Moreover, since the connecting rod 1332 is movably arranged in the pressure regulating mounting 131 along the axial direction of the infusion hole 111, when the abutting piece 133 moves, the connecting rod 1332 guides the moving direction of the abutting piece 133 in cooperation with the pressure regulating mounting 131, so as to avoid the deviation of the moving direction of the abutting piece 133.

[0041] In some embodiments, the reset elastic member 132 is a spring, the reset elastic member 132 is sleeved on the connecting rod 1332, and the reset elastic member 132 is in contact with the side wall of the connecting rod 1332. Through the above arrangement, since the reset elastic member 132 is sleeved on the connecting rod 1332 and in contact with the side wall of the connecting rod 1332, the connecting rod 1332 can also guide the extension and contraction of the reset elastic member 132, so as to avoid the reset elastic member 132 from being skewed and deviated during extension and contraction, thereby improving the stability of the extension and contraction of the reset elastic member 132.

[0042] In some embodiments, the diameter of the abutting head 1331 gradually increases from the end away from the connecting rod 1332 to the end close to the connecting rod 1332, the minimum diameter of the abutting head 1331 is smaller than the diameter of the communication port 121, and the maximum diameter of the abutting head 1331 is greater than the diameter of the communication port 121.

[0043] Through the above arrangement, at least part of the structure of the abutting head 1331 can be located in the communication port 121, so as to achieve sufficient plugging of the communication port 121. At least part of the structure of the abutting head 1331 can also be located outside the communication port 121, so as to avoid the abutting head 1331 from completely penetrating through the communication port 121 into the first hole section 1111. Therefore, the above arrangement can improve the plugging effect of the abutting head 1331 on the communication port 121.

[0044] In other embodiments, the abutting head 1331 can also be a cuboid, a cube or a flat plate structure, as long as the abutting head 1331 can plug the communication port 121 when the abutting head 1331 is in contact with the partition plate 12.

[0045] Please refer to Figure 4 In some embodiments, at least part of the structure of the pressure regulating mounting member 131 is spaced apart from the inner side wall of the second hole section 1112 to form a liquid passing port 1311. The liquid passing port 1311 is a channel for the liquid in the second hole section 1112 to pass through the pressure regulating mounting member 131, so as to ensure that the infusion hole 111 can smoothly discharge liquid. In the present embodiment, two liquid passing ports 1311 are provided, and the two liquid passing ports 1311 are symmetrically arranged about the axis of the infusion hole 111. When adjusting the position of the pressure regulating mounting member 131 in the second hole section 1112, the user can insert two fingers into the liquid passing ports 1311 and clamp the pressure regulating mounting member 131, and then rotate the pressure regulating mounting member 131, so as to achieve simple and convenient operation.

[0046] In other embodiments, the pressure regulating mounting member 131 can also be provided with a liquid passing hole, and the liquid in the second hole section 1112 can pass through the pressure regulating mounting member 131 through the liquid passing hole.

[0047] Please refer to Figure 5The embodiment also provides a flushing device 200 for flushing a machining center, the flushing device 200 comprising a flushing assembly 21.

[0048] The flushing assembly 21 comprises a liquid storage tank 211, a liquid delivery pipe 212, a liquid pump 213 and the nozzle device 100 provided in any of the above embodiments.

[0049] The liquid storage tank 211 is used for storing liquid required for flushing the machining center, such as cutting fluid, cooling fluid, etc. The flushing device 200 is described by taking the liquid in the liquid storage tank 211 as cutting fluid as an example.

[0050] The liquid delivery pipe 212 is a pipeline for delivering cutting fluid for the flushing device 200, and one end of the liquid delivery pipe 212 is in communication with the liquid storage tank 211.

[0051] The liquid pump 213 is a power component of the flushing device 200, and the liquid pump 213 is connected between the liquid delivery pipe 212 and the liquid storage tank 211, and is used for sucking the cutting fluid in the liquid storage tank 211 into the liquid delivery pipe 212.

[0052] The liquid inlet end 112 of the nozzle device 100 is connected to the liquid delivery pipe 212, and specifically connected to the end of the liquid delivery pipe 212 away from the liquid delivery tank.

[0053] Through the above arrangement, when the flushing device 200 is working, the liquid pump 213 is started, the liquid pump 213 sucks the cutting fluid in the liquid storage tank 211 into the liquid delivery pipe 212, and then the cutting fluid enters the liquid delivery hole 111 of the nozzle device along the liquid delivery pipe 212. Since the impact force of the cutting fluid on the abutting piece 133 is greater than the abutting force of the reset elastic piece 132 on the abutting piece 133, the abutting piece 133 will move away from the partition plate 12, thereby losing the plugging effect on the communication port 121. At this time, the cutting fluid can be smoothly sprayed out through the nozzle device 100. When the liquid pump 213 is closed, since the cutting fluid loses the driving force, the impact force of the cutting fluid on the abutting piece 133 is less than the abutting force of the reset elastic piece 132 on the abutting piece 133, so the abutting piece 133 will be abutted on the partition plate 12 again and the communication port 121 will be plugged under the action of the reset elastic piece 132, thereby avoiding the cutting fluid in the part of the liquid delivery pipe 212 between the liquid pump 213 and the nozzle device 100 from continuing to flow out from the nozzle device 100. In this way, when the staff pauses the liquid spraying to perform the tool changing operation during the machining process of the machining center, the liquid dripping out of the nozzle can be avoided from polluting the precision components such as the tool shank and the tool setting instrument in the internal area of the tool magazine, thereby avoiding affecting the precision of the related equipment.

[0054] In some embodiments, the flushing device 200 comprises two flushing assemblies 21, one of which is arranged to spray the machining tool of the machining center through the liquid outlet end 113 of the nozzle device 100, and the other is arranged to spray the chip groove 300 of the machining center through the liquid outlet end 113 of the nozzle device 100.

[0055] Through the above arrangement, one of the flushing assemblies 21 can spray the machining tool of the machining center and the machining workpiece to play a lubricating, cooling and cleaning effect on the machining workpiece, thereby improving the machining quality. The other flushing assembly 21 can flush the accumulated iron filings and other impurities in the chip groove 300, thereby improving the chip removal efficiency and cleaning effect of the chip groove 300. The above two flushing assemblies 21 can be used independently, so as not to interfere with each other, which is convenient and efficient.

[0056] In some embodiments, the flushing assembly 21 further comprises a handheld spray gun 214 in communication with the liquid delivery pipe 212. Due to the arrangement of the handheld spray gun 214, the staff can use the handheld spray gun 214 to spray any structure of the machining center, thereby expanding the flushing range of the flushing device 200, and being more flexible and convenient, and enriching the application scenarios of the flushing device 200.

[0057] In some embodiments, the nozzle device 100 in the flushing assembly 21 is arranged in plurality, the liquid inlet end 112 of each of the plurality of nozzle devices 100 is in communication with the liquid delivery pipe 212, and the liquid spraying directions of the plurality of nozzle devices 100 are different.

[0058] Through the above arrangement, the plurality of nozzle devices 100 can spray the machining tool and the chip groove 300 of the machining center from different directions, thereby improving the flushing effect and efficiency.
