Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, specifically a high-efficiency cooling spray device for CNC machine tools. Background Technology

[0002] In modern manufacturing, CNC machine tools are widely used, and their machining accuracy and efficiency are constantly improving. However, during CNC machine tool machining, a large amount of heat is generated between the cutting tool and the workpiece.

[0003] A search of Chinese utility model patent (publication number CN219189547U) reveals a water spraying device for CNC machine tool processing, including a vertical plate, a horizontal plate, a connecting seat, a housing, a water tank, a water pump, and a hose. This technical solution can change the spray angle fixed on the hinge rod, which facilitates cooling different parts of the workpiece and improves the cooling effect of the device.

[0004] However, through exploration, the inventors have discovered that this technical solution still has at least the following defects: Existing cooling spray devices, when left stagnant for extended periods, are prone to causing some components of the coolant to settle at the bottom of the tank. This results in uneven heat dissipation of the coolant, making it difficult for the cooling spray to achieve the desired cooling effect overall. Consequently, it becomes difficult to effectively control the temperature of the processing area, which in turn affects processing accuracy and surface quality. Utility Model Content

[0005] The present invention aims to provide a high-efficiency cooling spray device for CNC machine tools to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency cooling spray device for CNC machine tools includes a main body, a water tank detachably connected to the main body, a housing connected to the main body, a movable plate slidably connected to the housing, a clamping plate connected to the movable plate, the clamping plate cooperating with the water tank, a feed hopper connected to the water tank, a connecting pipe connected to the water tank, a water pump connected to the main body, the connecting pipe connected to the water pump inlet flange, a water outlet pipe connected to the water pump outlet flange, the water outlet pipe passing through the main body, a flexible hose connected to the water outlet pipe, a hinge rod movably connected to the main body, a spray head connected to the hinge rod, a flexible hose connected to the spray head, a servo motor connected to the water tank, a rotating shaft connected to the output end of the servo motor, the rotating shaft rotatably connected to the water tank, a connecting piece connected to the rotating shaft, a stirring rod connected to the connecting piece, and a through hole provided on the stirring rod.

[0007] Preferably, the main body is connected to a stepper motor, the output end of the stepper motor is connected to a bidirectional screw, the bidirectional screw is rotatably connected to the main body and the housing, and the movable plate is movably connected to the bidirectional screw.

[0008] Preferably, the clamping plate is connected to a positioning block, and the water tank has a positioning groove, with the positioning block and the positioning groove cooperating with each other.

[0009] Preferably, the main body is slidably connected to a sliding block, the sliding block is rotatably connected to a movable rod, the movable rod is rotatably connected to a hinge rod, the sliding block is rotatably connected to a threaded rod, the main body is connected to a connecting seat, and the threaded rod is threadedly connected to the connecting seat.

[0010] Preferably, the sliding block is connected to a drive motor, and the threaded rod is connected to the output end of the drive motor.

[0011] Preferably, the sliding block is connected to a T-shaped block, the main body has a T-shaped groove, and the T-shaped block is slidably connected to the T-shaped groove.

[0012] Preferably, the main body is connected to a horizontal plate, the horizontal plate is connected to a mounting plate, and the mounting plate has mounting holes.

[0013] Preferably, the water tank is connected to a transparent observation window.

[0014] The beneficial effects of this technical solution compared to existing technologies are as follows: (1) This solution, by setting up a servo motor, rotating shaft, connecting parts, and stirring rod, can fully stir the coolant in the water tank, so that the various additives in the coolant can be evenly dispersed, avoiding local concentrations that are too high or too low due to sedimentation. The uniform coolant composition can better exert its cooling and lubrication effects, effectively reducing the heat generated during processing, reducing friction between the tool and the workpiece, and thus improving processing quality. When the coolant composition is uniform, its heat exchange efficiency is higher. Stirring makes the coolant flow continuously in the water tank, allowing for more thorough heat exchange with the external environment, ensuring that the coolant always maintains a low temperature. During spray cooling, the low temperature and uniform composition of the coolant can more effectively remove heat from the processing area, improving the cooling effect and preventing workpiece deformation or quality defects due to overheating. By setting through holes, the stirring effect is further enhanced. During stirring, the coolant can flow through the through holes on both sides of the stirring rod, increasing the flow path and turbulence of the coolant, making the coolant mix more thoroughly. This not only helps prevent sedimentation but also improves the uniformity of the coolant, thereby better utilizing the performance of the coolant.

[0015] (2) By setting a stepper motor and a bidirectional screw, the movable plate can be driven to slide on the housing. The clamping plate connected to the movable plate can be adjusted in position according to the size of the water tank, thereby achieving clamping and fixing of water tanks of different sizes. This improves the versatility and flexibility of the device, eliminating the need to design special fixing devices for water tanks of different sizes, reducing production costs and installation and debugging difficulties. It effectively saves installation time and improves work efficiency.

[0016] (3) By setting up positioning blocks and positioning slots, not only is precise positioning achieved, but the stability of the water tank after installation is also enhanced. During the operation of the machine tool, vibration and impact may occur. The structure of the positioning blocks and positioning slots can effectively prevent the water tank from shifting or loosening under these external forces. Stable water tank installation helps to maintain the normal supply and circulation of coolant, ensuring the reliability and stability of the cooling spray device.

[0017] (4) By setting up a sliding block, a movable rod, a threaded rod, a connecting seat, and a drive motor, when the sliding block moves, the movable rod and the hinge rod will rotate accordingly, thereby realizing the adjustment of the angle and position of the spray head. This allows the operator to flexibly adjust the direction and position of the spray head according to the shape, size, and processing location of the workpiece, so that the coolant can be accurately sprayed onto the area that needs cooling, ensuring that the coolant fully covers the processing area, avoiding waste of coolant and the occurrence of cooling blind spots. Accurate cooling spray can effectively reduce the temperature of the processing area, reduce thermal deformation, and improve processing accuracy and surface quality.

[0018] (5) By setting T-blocks and T-slots, the sliding block can move smoothly along the predetermined track, avoiding inaccurate spray head adjustment or unstable device operation caused by offset or shaking. The angle and position of the spray head can be controlled more precisely, so that the coolant can be sprayed more accurately onto the processing area.

[0019] (6) The installation of the device is facilitated by the horizontal plate, mounting plate and mounting holes. The device can be firmly installed in a suitable position on the CNC machine tool to ensure the stability of the device during operation. The firm installation can ensure that the device remains stable during the operation of the machine tool and avoid the cooling spray effect being affected by the device loosening or shaking.

[0020] (7) By setting up a transparent observation window, operators can observe the coolant level in the water tank at any time to determine whether the coolant needs to be replenished. At the same time, the observation window also allows for a direct view of the coolant's color, transparency, and other status indicators, enabling operators to determine whether the coolant has deteriorated or become contaminated. Timely understanding of the coolant's status helps operators take appropriate measures to ensure the coolant's performance and cooling effect. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: like Figure 1-3The high-efficiency cooling spray device for CNC machine tools shown includes a main body 4, with a water tank 7 detachably connected inside the main body 4. The water tank 7 is used to hold coolant. A shell 18 is connected to the top of the inner wall of the main body 4. Movable plates 17 are symmetrically slidably connected to both ends of the inner wall of the shell 18. Clamping plates 6 are connected to the bottom of the two movable plates 17 respectively. The clamping plates 6 cooperate with the water tank 7. A feed hopper 16 is connected to the top of the water tank 7 to facilitate the addition of coolant to the water tank 7. The water tank 7 is connected to a connecting pipe 32. The main body 4 is connected to... A water pump 19 is connected to the main body 4. A connecting pipe 32 is connected to the inlet flange of the water pump 19, and an outlet pipe 20 is connected to the outlet flange of the water pump 19. The flange connection ensures the sealing and stability of the connection. The outlet pipe 20 passes through the main body 4, and a flexible hose 21 is connected to the end of the outlet pipe 20 away from the water pump 19. A hinge rod 23 is movably connected to the bottom of the main body 4, and a spray head 22 is connected to the other end of the hinge rod 23. The flexible hose 21 is connected to the spray head 22. The flexible hose 21 has a certain degree of flexibility, which facilitates the adjustment of the position and angle of the spray head 22. When the water pump 19 is working, it draws out the coolant from the water tank 7 and delivers it out through the outlet pipe 20, leading the coolant to the spray head 22. After the coolant is delivered to the spray head 22 through the flexible hose 21, it is sprayed onto the machining area of ​​the CNC machine tool in the form of a spray, thereby achieving the cooling function. A servo motor 5 is connected to the outer wall of the water tank 7. The output end of the servo motor 5 is connected to a rotating shaft 8, which is rotatably connected to the water tank 7. The rotating shaft 8 is connected to several connecting parts 9, each of which is connected to several stirring rods 10. Each stirring rod 10 has several through holes 11. When the servo motor 5 starts, it drives the rotating shaft 8 to rotate within the water tank 7. As the shaft 8 rotates, the stirring rods 10 perform circular motion within the water tank 7, stirring the coolant. During the stirring process, the coolant can flow through the through holes 11, increasing the agitation and mixing of the coolant, ensuring a uniform distribution of its components, preventing sedimentation, and guaranteeing stable cooling and lubrication performance.

[0023] like Figure 1 As shown, a stepper motor 14 is connected to the top of the outer wall of the main body 4. A bidirectional screw 15 is connected to the output end of the stepper motor 14. The bidirectional screw 15 is rotatably connected to the main body 4 and the housing 18. Two movable plates 17 are movably connected to the outer wall of the bidirectional screw 15. Due to the special structure of the bidirectional screw 15, when it rotates, the two movable plates 17 can slide towards or away from each other on the inner wall of the housing 18, thereby realizing the clamping or loosening operation of the clamping plate 6 on the water tank 7, which facilitates the installation and disassembly of the water tank 7, and can also accommodate water tanks 7 of different sizes. Several positioning blocks 12 are connected to the opposite side of the two clamping plates 6. The water tank 7 has positioning grooves 13 corresponding to the positioning blocks 12. Each positioning block 12 cooperates with the corresponding positioning groove 13 to ensure the stability and accuracy of the installation of the water tank 7. When the clamping plate 6 clamps the water tank 7, the positioning block 12 is embedded in the positioning groove 13, which can prevent the water tank 7 from shaking or shifting during use.

[0024] like Figure 2 As shown, a sliding block 26 is slidably connected to the bottom of the main body 4. A movable rod 24 is rotatably connected to the sliding block 26, and the other end of the movable rod 24 is rotatably connected to a hinge rod 23. When the sliding block 26 moves, the movable rod 24 drives the hinge rod 23 to rotate, thereby adjusting the angle of the spray head 22. A threaded rod 28 is rotatably connected to one end of the sliding block 26, and a connecting seat 27 is connected to the bottom of the main body 4. The threaded rod 28 is threadedly connected to the connecting seat 27. After the drive motor 25 starts, it drives the threaded rod 28 to rotate. Due to the threaded engagement between the threaded rod 28 and the connecting seat 27, the sliding block 26 slides linearly at the bottom of the main body 4, thereby adjusting the position of the spray head 22. The sliding block 26 is connected to the drive motor 25, and the threaded rod 28 is connected to the output end of the drive motor 25. The top of the sliding block 26 is connected to a T-shaped block 30, and the bottom of the main body 4 is provided with a T-shaped groove 29. The T-shaped block 30 and the T-shaped groove 29 are slidably connected, which provides guidance and constraint for the sliding of the sliding block 26, ensuring the stability and accuracy of the movement of the sliding block 26, and preventing it from deviating or shaking during the movement.

[0025] like Figure 1 As shown, the main body 4 has horizontal plates 2 connected to both ends, and mounting plates 1 are connected to the two horizontal plates 2 respectively. Each mounting plate 1 has several mounting holes 3. Through these mounting holes 3, bolts or other connecting parts 9 can be used to install the device in a suitable position on the CNC machine tool. The layout of the mounting holes 3 can be adjusted and arranged according to the specific installation requirements of the machine tool, improving the adaptability of the device and meeting the installation needs of different CNC machine tools.

[0026] like Figure 2 As shown, the water tank 7 is connected to a transparent observation window 31. Operators can visually observe the coolant level and condition within the water tank 7 through the transparent observation window 31. This allows for timely monitoring of coolant usage, enabling prompt replenishment when insufficient or replacement if any abnormalities occur, ensuring the normal operation and cooling effect of the cooling spray device.

[0027] The specific implementation process is as follows: First, the device is installed in a suitable position on the CNC machine tool using bolts and other connecting parts 9 through the mounting holes 3. Then, the water tank 7 is placed inside the main body 4, and the stepper motor 14 is started, driving the bidirectional screw 15 to rotate. Due to the special structure of the bidirectional screw 15, the movable plates 17 at both ends of the inner wall of the housing 18 slide towards each other, and the clamping plate 6 at the bottom of the movable plate 17 gradually approaches the water tank 7. This continues until the positioning block 12 on the clamping plate 6 is embedded in the corresponding positioning groove 13 of the water tank 7, ensuring the stability and accuracy of the water tank 7 installation, thus completing the fixing of the water tank 7. Coolant is added through the feed hopper 16, and the servo motor 5 is started, driving the rotating shaft 8 to rotate. The connecting parts 9 and the stirring rod 10 on the rotating shaft 8 then perform circular motion, stirring the coolant in the water tank 7. During stirring, the coolant flows through the through hole 11 on the stirring rod 10, increasing the turbulence and mixing degree of the coolant. The water pump 19 connected to the main body 4 is turned on, and the water pump 19 draws coolant from the water tank 7 through the connecting pipe 32. The coolant is delivered through the outlet pipe 20, and then through the hose 21 to the spray head 22. The spray head 22 sprays the coolant into the machining area of ​​the CNC machine tool in the form of a spray, thereby achieving the cooling function of the machining area.

[0028] When it is necessary to adjust the angle of the spray head 22, the drive motor 25 is started. The drive motor 25 controls the forward and reverse rotation of the threaded rod 28, causing the sliding block 26 to slide left and right along the T-slot 29. The movable rod 24 moves with the sliding block 26, driving the hinge rod 23 to rotate, thereby realizing the adjustment of the angle of the spray head 22.

[0029] When the water tank 7 needs cleaning, repair, or replacement, start the stepper motor 14 to make the bidirectional screw 15 rotate in the opposite direction. The movable plates 17 at both ends of the inner wall of the housing 18 slide in opposite directions, and the clamping plate 6 loosens its clamping on the water tank 7. Remove the water tank 7 from the main body 4 for the corresponding maintenance operations.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
