Description

Technical Field

[0001] This application relates to the field of water cooling technology for CNC machine tool processing, specifically to an external annular water spray device for CNC machine tool processing. Background Technology

[0002] The core function of the water-cooled structure of CNC machine tools is to forcibly reduce the cutting temperature through circulating coolant, prevent the tool from wearing out too quickly due to high-temperature annealing, and reduce workpiece thermal deformation to ensure machining accuracy. At the same time, it also has the functions of lubrication and friction reduction to improve surface quality, as well as flushing chips to avoid entanglement and scratching of the workpiece. It is an indispensable key structure to ensure efficient and high-precision machining.

[0003] During CNC machine tool machining, spray nozzles are usually installed above the cutting tool to spray water and cool it. However, when using a single nozzle or multiple dispersed nozzles for water cooling, the cooling and rinsing range of the tool is often not comprehensive enough, making it difficult to cover all heat-generating areas, thus reducing the overall cooling effect. At the same time, this method is not convenient for effectively flushing away the chips generated during machining from the cutting area, affecting the convenience of CNC machine tool machining.

[0004] To address the aforementioned technical problems, patent number 202222054944.X discloses a water-cooling device for a CNC machine tool used for parts processing. The specification states that this application relates to a water-cooling device for a CNC machine tool used for parts processing, comprising a machine tool body and an operating table mounted on the machine tool body. A support arm is slidably mounted on the operating table, and a water tank is mounted on the top of the support arm. A water trough is formed inside the machine tool body, and a recovery pump is installed on one side of the water trough. The input end of the recovery pump is connected to the water trough, and a flexible hose is connected to the output end of the recovery pump. The top end of the flexible hose is connected to the water tank. An electromagnet absorption plate is also installed inside the water trough, and a processing mold is mounted on the bottom of the support arm. A water pipe is installed on the side of the processing mold. In this application, the electromagnet absorption plate can adsorb metal debris in the water trough, filtering out the metal debris from the water. Then, the recovery pump can pump the water back to the water tank through the flexible hose, enabling direct water recycling and facilitating water conservation. Utility Model Content

[0025] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0029] The existing technology has the following drawbacks: during the process of cooling the tool by spraying water with a single nozzle or multiple dispersed nozzles, the cooling and rinsing range of the tool is often not comprehensive enough, making it difficult to cover all heat-generating areas, thereby reducing the overall cooling effect. At the same time, this method is not convenient for effectively flushing away the debris generated during processing from the cutting area, which affects the convenience of CNC machine tool processing.

[0030] As an improvement, such as Figure 1 - Figure 6 As shown, the preferred embodiment of this application is as follows:

[0031] The CNC machine tool machining external annular water spray device includes a frame plate 1. A positioning frame 5 is fixedly connected to the lower front of the frame plate 1. A motor 10 is fixedly installed on the inner wall of the positioning frame 5. A cleaning component 6 is provided below the motor 10. The cleaning component 6 includes an auxiliary plate 603 fixedly installed below the motor 10. An inner sleeve plate 607 is movably installed on the outer wall of the auxiliary plate 603. A positioning plate 605 is fixedly connected to the outer wall of the inner sleeve plate 607. An annular hollow pipe 608 is fixedly connected below the positioning plate 605. A sloping groove ring 610 is fixedly connected below the inclined surface of the annular hollow pipe 608. The bottom of the sloping groove ring 610 has several lateral sloping grooves evenly distributed around its circumference. Hole 609, and the oblique hole 609 penetrates the outer wall of the annular hollow tube 608. The side wall of the annular hollow tube 608 is provided with a guide tube 601, which penetrates the side wall of the annular hollow tube 608. It is installed on the outer wall of the auxiliary plate 603 by a headless bolt 604 through the positioning hole 606 of the positioning plate 605 and locked on all four sides. After completion, during the processing, the water flow is introduced into the annular hollow tube 608 along the guide tube 601. The water flow fills the annular hollow tube 608 and is discharged from the oblique hole 609 with water pressure. It is guided by the inclined groove ring 610 and sprayed towards the tool 9 below the motor 10 to clean the residual debris on the surface of the tool 9.

[0032] By using a headless bolt 604 to insert into the auxiliary plate 603 below the motor 10, the positioning plate 605 is positioned in multiple directions. An annular hollow pipe 608 is installed below the positioning plate 605, and water is sprayed out from the channel of the guide pipe 601 through the side inclined hole 609. The water is guided by the inclined groove ring 610 and sprayed onto the tool 9. This allows the tool 9 to be rinsed with an annular water flow, which cools it down. The enveloping water flow thoroughly cleans the debris on the surface of the tool 9 and the workpiece, improving the rinsing quality.

[0033] An upper ring plate 611 is fixedly connected above the inner sleeve plate 607. The upper ring plate 611 is movably connected to the auxiliary plate 603. The upper ring plate 611 above the inner sleeve plate 607 is connected to the auxiliary plate 603. An auxiliary headless bolt 604 is inserted into the positioning hole 606 and spliced ​​with the auxiliary plate 603.

[0034] The outer wall of the positioning disk 605 has four positioning holes 606 evenly distributed around its circumference. One end of each positioning hole 606 passes through the inner sleeve plate 607. A headless bolt 604 is movably connected to the inner wall of the positioning hole 606. One end of the headless bolt 604 is movably connected to the outer wall of the auxiliary disk 603. The protective component 7 below the positioning disk 605 has the headless bolt 604 inserted through the positioning hole 606 on the outer wall of the positioning disk 605 and is connected to the auxiliary disk 603 below the motor 10. This allows for multi-angle positioning and installation to prevent the positioning disk 605 from shifting due to vibration during processing.

[0035] The outer wall of the guide tube 601 is movably connected to the slide frame 602. The other side of the slide frame 602 is fixedly installed on the outer wall of the positioning frame 5. The guide tube 601 is in the slide frame 602 on the side wall of the positioning frame 5 to prevent the guide tube 601 from hanging down and affecting the rotation and machining process of the tool 9.

[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the protective component 7 includes several side grooves 701 evenly distributed around the surface of the positioning disk 605, with the edge of the annular hollow tube 608 penetrating below the side grooves 701. A connecting rod 705 is movably connected to the lower inner wall of the side groove 701. A limiting groove 707 is formed on the side of the connecting rod 705. A fan-shaped protective membrane 708 is fixedly connected between the connecting rods 705. A pulley 706 is movably installed at the end of the connecting rod 705 away from the positioning disk 605. During machining, water is directed through the oblique hole 609 to rinse the tool 9. The impact generates splashing water, which may affect the motor 10. Therefore, four connecting rods 705 are used as a frame structure, with fan-shaped protective membranes 708 connected between them, and these membranes possess a certain degree of elasticity. The connecting rod 705 is wrapped around the top of the cutting tool 9 to separate the cutting tool 9 from the motor 10, preventing the water used to wash the cutting tool 9 from splashing onto the motor 10. During the machining process, when the cutting tool 9 is driven downward by the machine tool, the pulley 706 at one end of the connecting rod 705 rolls on the surface of the workpiece, which reduces the angle between the connecting rod 705 and the workpiece. The connecting rod 705, through the movable connection between the sliding sleeve 709 and the sliding rod 704, pushes the auxiliary rod 702 to follow the movement. During the downward pressing process, the sliding sleeve 709 compresses the spring 703. After the cutting tool 9 is driven upward by the machine tool, the spring 703 loses its compression and uses the rebound force to rotate the connecting rod 705 at the connection point of the side groove 701. During the workpiece machining process, the fan-shaped protective film 708 can also prevent the debris from splashing upward during the machining process.

[0037] The four connecting rods 705 are connected by the side grooves 701 in the positioning plate 605, and the auxiliary rods 702 provide auxiliary support. The auxiliary rods 702 and the connecting rods 705 are connected by the sliding sleeves 709 and the sliding rods 704. A fan-shaped protective membrane 708 is set between the four connecting rods 705 to separate the motor 10 and the tool 9. This can isolate and protect the motor 10 during the washing process of the tool 9, prevent water mist from affecting the normal operation of the motor 10, and also prevent the tool 9 from generating flying debris during the rotation process, thus preventing safety hazards.

[0038] A sliding rod 704 is fixedly connected to the inner wall of the limiting groove 707. A sliding sleeve 709 is movably connected to the outer wall of the sliding rod 704. A secondary rod 702 is movably connected to the outer wall of the sliding sleeve 709. The other end of the secondary rod 702 is movably installed on the inner wall of the side groove 701. Its sliding sleeve 709 slides on the outer wall of the sliding rod 704, pushing the secondary rod 702 to change its angle in the side groove 701. The auxiliary connecting rod 705 is adjusted at the angle below the positioning plate 605 to prevent the connecting rod 705 from interfering with the machining.

[0039] One end of the sliding sleeve 709 is fixedly connected to a spring 703, and the other end of the spring 703 is fixedly installed on the inner wall of the limiting groove 707. The connecting rod 705 drives the auxiliary rod 702 to change angle through the sliding sleeve 709, which will stretch or compress the spring 703. After the applied force is lost, the spring 703 will drive the sliding sleeve 709 back to its original position and push the connecting rod 705 to the initial position.

[0040] The rear end of the frame plate 1 is symmetrically and evenly distributed with two slides 4. The inner wall of the slides 4 is movably connected with auxiliary rods 3. The two ends of the two auxiliary rods 3 are fixedly connected with frames 2. The drive structure drives the frame plate 1 to move vertically up and down within the frames 2. The sliding connection between the slides 4 and the auxiliary rods 3 assists the frame plate 1 with the cutter 9 to perform the lifting and lowering operation.

[0041] The output end of the motor 10 is fixedly connected to the locking frame 8 through the auxiliary disk 603. The tool 9 is located below the locking frame 8. The locking frame 8 is used to hold the tool 9 to facilitate the switching of the tool 9 and adapt to different processing needs.

[0042] The working principle of this application is as follows: The operator installs the overall structure onto the CNC machine tool using the frame plate 1, and adds a cleaning structure below the motor 10. A headless bolt 604 is passed through the positioning hole 606 of the positioning plate 605 and installed on the outer wall of the auxiliary plate 603 for circumferential locking. After completion, during processing, water flows along the guide tube 601 into the annular hollow pipe 608. The water fills the annular hollow pipe 608 and, with water pressure, is discharged from the side inclined hole 609, guided by the inclined groove ring 610, and sprayed onto the tool 9 below the motor 10 to clean the residual debris on the surface of the tool 9. During the water flow rinsing of the tool 9, the water flow is discharged through the side inclined hole 609 to rinse the tool 9. Due to the impact, splashing water will be generated. This splashing water may affect the motor 10, so four connecting rods 705 are used as the frame structure. The structure consists of interconnected fan-shaped protective films 708 with a certain degree of elasticity, surrounding the cutter 9 and separating it from the motor 10 to prevent water from splashing onto the motor 10. During CNC machining, the pulley 706 at one end of the connecting rod 705 rolls on the surface of the workpiece, reducing the angle between the connecting rod 705 and the workpiece. The connecting rod 705, through the movable connection between the sliding sleeve 709 and the sliding rod 704, pushes the auxiliary rod 702 to follow the movement. When the sliding sleeve 709 is pressed down, it compresses the spring 703. After the cutter 9 is driven upward by the machine tool, the spring 703 loses its compression and rebounds, causing the connecting rod 705 to rotate at the connection point of the side groove 701. During the workpiece machining process, the fan-shaped protective films 708 also prevent debris from splashing upward during machining.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.
