Technical Field
[0001] This utility model relates to the field of CNC machining technology, and more specifically, to a rotary jetting structure. Background Technology
[0002] During CNC machining, a spray structure is used to spray coolant onto the workpiece and machining tool, simultaneously cooling and reducing dust. To achieve comprehensive cooling and dust reduction, a rotating spray structure is used, which rotates around the workpiece. To save energy, the used coolant is filtered and reused. However, this leaves a small amount of particulate matter in the coolant, which may clog the spray structure and affect normal operation. Utility Model Content
[0003] To overcome the shortcomings of the prior art, this utility model provides a rotary injection structure that has the advantage of avoiding clogging.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary spraying structure, including a CNC machining table and a mounting table. The mounting table is disposed in the inner cavity of the CNC machining table. A filter chamber is fixedly connected to the left side of the mounting table. A filter plate is fixedly connected to the inner cavity of the filter chamber. A return spring is fixedly connected to the outer side of the filter chamber. A movable rod is fixedly connected to the side of the return spring away from the filter chamber. A moving rod is fixedly connected to the side of the movable rod close to the filter chamber. A scraper is fixedly connected to the surface of the moving rod. A rotating wheel is movably sleeved in the inner cavity of the mounting table. An anti-slip wheel is fixedly connected to the bottom end of the rotating wheel. A rotating rod is fixedly connected to the bottom end of the anti-slip wheel.
[0005] As a preferred embodiment of this utility model, an electromagnet is fixedly connected to the inner cavity of the filter chamber, a collection box is slidably connected to the bottom of the inner cavity of the filter chamber, and a pressure sensor is fixedly connected to the inner cavity of the filter chamber.
[0006] As a preferred embodiment of this utility model, the mounting platform is provided with an oil inlet groove near the filter chamber, the rotating wheel is provided with an annular groove in the middle, and the anti-slip wheel and the rotating wheel are provided with oil delivery grooves in their inner cavities.
[0007] As a preferred embodiment of this utility model, a spray head is fixedly connected to the bottom end of the oil delivery tank, the annular groove and the inner cavity of the oil delivery tank are interconnected, sealing rings are fixedly fitted on the upper and lower sides of the rotating wheel, and a fixing ring is fixedly connected to the top of the mounting platform.
[0008] As a preferred embodiment of this utility model, a drive motor is fixedly connected to the right side of the mounting platform, a drive wheel is fixedly mounted on the output shaft of the drive motor, a transmission belt is movably sleeved on the surface of the drive wheel, and the drive wheel is connected to the anti-slip wheel through the transmission belt.
[0009] As a preferred embodiment of this utility model, the pressure sensor and the electromagnet are electrically connected, and a magnetic plate is fixedly connected to the top of the collection box. The collection box is magnetically connected to the filter chamber through the magnetic plate.
[0010] In a preferred embodiment of this invention, the scraper is in contact with the surface of the filter plate, the moving rod is located at the center of the inner cavity of the return spring, and the movable rod is located on the moving path of the rotating rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model connects the coolant input device to the filter chamber, allowing the coolant to enter the inner cavity of the filter chamber and be filtered by the filter plate. When the anti-slip wheel drives the rotating rod to the movable rod, the rotating rod pushes the movable rod, which in turn moves the moving rod, which in turn moves the scraper. At this time, the scraper removes the debris remaining on the outer surface of the filter plate, thus achieving a second filtration of the coolant through the filter plate. This prevents residual debris in the reused coolant from clogging the spray nozzle. Furthermore, the movement of the scraper ensures that the filter plate remains clean at all times.
[0013] 2. This utility model uses a collection box to press the pressure sensor, causing the electromagnet to generate magnetic force, which adsorbs metal particles in the coolant. When the collection box is pulled out of the inner cavity of the filter chamber, the pressure sensor separates from the collection box. At this time, the electromagnet loses its magnetic force, causing the adsorbed metal particles to fall off. This reduces the filtration pressure of the filter plate while adsorbing metal particles individually. Furthermore, when the collection box is pulled out to collect debris, the electromagnet is automatically de-energized. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 8 As shown, this utility model provides a rotary spraying structure, including a CNC machining table 1 and a mounting table 2. The mounting table 2 is disposed in the inner cavity of the CNC machining table 1. A filter chamber 14 is fixedly connected to the left side of the mounting table 2. A filter plate 15 is fixedly connected to the inner cavity of the filter chamber 14. A return spring 16 is fixedly connected to the outer side of the filter chamber 14. A movable rod 17 is fixedly connected to the side of the return spring 16 away from the filter chamber 14. A moving rod 18 is fixedly connected to the side of the movable rod 17 close to the filter chamber 14. A scraper 19 is fixedly connected to the surface of the moving rod 18. A rotating wheel 8 is movably sleeved in the inner cavity of the mounting table 2. An anti-slip wheel 7 is fixedly connected to the bottom end of the rotating wheel 8. A rotating rod 24 is fixedly connected to the bottom end of the anti-slip wheel 7.
[0025] By connecting the coolant input device to the filter chamber 14, the coolant enters the inner cavity of the filter chamber 14 and is filtered by the filter plate 15. When the anti-slip wheel 7 drives the rotating rod 24 to the movable rod 17, the rotating rod 24 can push the movable rod 17. The movable rod 17 drives the moving rod 18 to move, and the moving rod 18 drives the scraper 19 to move. At this time, the scraper 19 scrapes off the debris remaining on the outer surface of the filter plate 15, thereby achieving the second filtration of the coolant by the filter plate 15. This avoids the residue in the reused coolant from causing the spray head 6 to be blocked. The movement of the scraper 19 also ensures that the filter plate 15 can be kept clean at all times.
[0026] An electromagnet 22 is fixedly connected to the inner cavity of the filter chamber 14, a collection box 20 is slidably connected to the bottom of the inner cavity of the filter chamber 14, and a pressure sensor 23 is fixedly connected to the inner cavity of the filter chamber 14.
[0027] Pressing the pressure sensor 23 by the collection box 20 causes the electromagnet 22 to generate magnetic force, which adsorbs metal particles in the coolant. When the collection box 20 is pulled out of the inner cavity of the filter chamber 14, the pressure sensor 23 separates from the collection box 20. At this time, the electromagnet 22 loses its magnetic force, causing the adsorbed metal particles to fall off. This reduces the filtration pressure of the filter plate 15 while adsorbing metal particles individually. Furthermore, when the collection box 20 is pulled out to collect debris, the electromagnet 22 is automatically de-energized.
[0028] Among them, the mounting platform 2 is provided with an oil inlet groove 11 near the filter chamber 14, the rotating wheel 8 is provided with an annular groove 13 in the middle, and the anti-slip wheel 7 and the inner cavity of the rotating wheel 8 are provided with an oil delivery groove 12.
[0029] After entering the inner cavity of the filter chamber 14 through the coolant, it then enters through the oil inlet 11, and then enters the inner cavity of the spray head 6 along the annular groove 13 and the oil delivery groove 12, and is then sprayed onto the surface of the workpiece from the spray head 6.
[0030] Among them, the bottom end of the oil tank 12 is fixedly connected to the injection head 6, the annular groove 13 is connected to the inner cavity of the oil tank 12, the upper and lower sides of the rotating wheel 8 are fixedly fitted with sealing rings 9, and the top of the mounting platform 2 is fixedly connected with a fixing ring 10.
[0031] Through the spray head 6 at the bottom of the oil delivery tank 12, and the connection between the annular groove 13 and the inner cavity of the oil delivery tank 12, the coolant can still enter the inner cavity of the oil delivery tank 12 while the anti-slip wheel 7 and the rotating wheel 8 are rotating. Then, it enters the spray head 6 along the inner cavity of the oil delivery tank 12, and is then sprayed from the spray head 6 to the surface of the workpiece to cool and reduce dust.
[0032] Among them, a drive motor 3 is fixedly connected to the right side of the mounting platform 2, and a drive wheel 4 is fixedly mounted on the output shaft of the drive motor 3. A transmission belt 5 is movably sleeved on the surface of the drive wheel 4, and the drive wheel 4 is connected to the anti-slip wheel 7 through the transmission belt 5.
[0033] The drive motor 3 is started to drive the drive wheel 4 to rotate, and the rotation of the drive wheel 4 drives the transmission belt 5 to rotate. The rotation of the transmission belt 5 drives the anti-slip wheel 7 to rotate. At this time, the rotation of the anti-slip wheel 7 drives the spray head 6 to rotate to cool and reduce dust on the workpiece.
[0034] Among them, the pressure sensor 23 and the electromagnet 22 are electrically connected, and the top of the collection box 20 is fixedly connected to the magnetic plate 21. The collection box 20 is magnetically connected to the filter chamber 14 through the magnetic plate 21.
[0035] The pressure sensor 23 and the electromagnet 22 are connected by telecommunications. When the collection box 20 presses the pressure sensor 23, it can send a signal to the external control device. Then the control device controls the electromagnet 22 to start. The start of the electromagnet 22 generates magnetic force to magnetically attract the metal particles in the coolant.
[0036] Among them, the scraper 19 is in contact with the surface of the filter plate 15, the moving rod 18 is located at the center of the inner cavity of the return spring 16, and the movable rod 17 is located on the moving path of the rotating rod 24.
[0037] By having the scraper 19 adhere to the surface of the filter plate 15, the scraper 19 can scrape away debris from the surface of the filter plate 15. The moving rod 18 is located at the center of the inner cavity of the return spring 16, so that the return spring 16 can evenly drive the moving rod 18 to move. The moving rod 17 is located on the moving path of the rotating rod 24, so that the rotating rod 24 can drive the moving rod 17 to move. The moving rod 17 then drives the scraper 19 to move and clean the outer surface of the filter plate 15.
[0038] The working principle and usage process of this utility model are as follows: The coolant input pipe is connected to the filter chamber 14, the coolant enters the inner cavity of the filter chamber 14 and is filtered by the filter plate 15. Due to the contact between the collection box 20 and the pressure sensor 23, the electromagnet 22 is always in the open state, thereby capturing the residual metal particles in the coolant.
[0039] Next, the coolant enters the oil supply tank 12 along the annular groove 13, and is sprayed onto the surface of the workpiece from the spray nozzle 6 at the bottom of the oil supply tank 12. Then, the drive motor 3 drives the drive wheel 4 to rotate, the drive wheel 4 drives the transmission belt 5 to rotate, the transmission belt 5 drives the anti-slip wheel 7 to rotate, and the anti-slip wheel 7 drives the spray nozzle 6 to rotate, so that the spray nozzle 6 can cool and reduce dust on the surface of the workpiece in all directions. When the anti-slip wheel 7 drives the rotating rod 24 to contact the movable rod 17, it pulls the movable rod 17 away from the filter chamber 14, thereby driving the scraper 19 to scrape off the debris that may accumulate on the outer surface of the filter plate 15.
[0040] After prolonged use, the coolant inside the filter chamber 14 is completely drained, and the debris hanging on the filter plate 15 falls into the inner cavity of the collection box 20. Then, the collection box 20 is pulled out from the inner cavity of the filter chamber 14. At this time, the collection box 20 is separated from the pressure sensor 23, and the pressure sensor 23 transmits the signal to the external control device. The external control device then controls the electromagnet 22 to close, so that the metal particles fall into the inner cavity of the collection box 20 to complete the collection.
