Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tool processing, in particular to a cooling liquid spraying device for numerical control machine tools. Background Art

[0002] CNC machine tools are automated machine tools equipped with a program control system. They integrate multiple technologies such as mechanics, electrical, hydraulic, pneumatic, microelectronics and information. CNC machine tools use pre-programmed processing programs to precisely control the movements of the machine tools. During the processing, the CNC system can control the movement of each coordinate axis of the machine tool, including linear and rotary motion, according to program instructions to achieve precise processing of the workpiece. It has the characteristics of high precision, high speed and high degree of automation. CNC machine tools can process parts of various complex shapes, such as curves and surfaces, and are widely used in many fields such as aerospace, automobile manufacturing, and mold processing. Compared with traditional machine tools, CNC machine tools have greatly improved production efficiency and processing accuracy, reduced human errors, and also reduced labor intensity, providing strong technical support for the development of modern manufacturing.

[0003] A Chinese patent application, published in CN115476196A, discloses a multi-angle coolant injection device for CNC machine tools. The device comprises an annular bracket, a coolant nozzle disposed on the annular bracket, a row of coolant nozzles disposed on the coolant nozzle, and a number of coolant flow channels within the coolant nozzle equal to the number of coolant nozzles. Each coolant flow channel is connected to a coolant nozzle at one end, and a coolant inlet is disposed on the end face of the coolant nozzle at the other end. The coolant inlets are distributed in an annular array at equal intervals on the end face of the coolant nozzle. The device also comprises an electromagnetic integrated valve assembly, the electromagnetic integrated valve assembly having a main flow valve port and a number of diverter valve ports equal to the number of coolant nozzles. A diverter pipe is connected between the diverter valve port and the coolant nozzle, and a reversing valve connected to the end of the coolant nozzle is disposed between the diverter pipe and the coolant nozzle. The coolant injection device features adjustable injection angles and uniform cooling, and is fully functional and highly practical.

[0004] During use, the above-mentioned device changes the spray position by setting up multiple water spray pipes and adopting independent control of solenoid valves. However, during its actual use, each spray pipe is in a fixed state, and it is impossible to flexibly adjust the specific angle direction of each spray pipe. It is inconvenient to further adjust the specific angle of each spray pipe during the overall use. There is still a certain spray gap in the overall use. Since the overall coolant supply is prone to dead corners, it is inconvenient to use, so it needs to be improved. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of the present utility model is to provide a coolant spraying device for a numerical control machine tool to solve the problems raised in the background art.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] A coolant spraying device for a numerical control machine tool includes a machine tool processing head. An installation frame is fixedly installed on the top of the machine tool processing head. A ring-shaped water supply pipe is fixedly installed on the outside of the installation frame. One end of the ring-shaped water supply pipe is fixedly connected to a water connection pipe.

[0027] Principle of use and advantages: By setting up the transmission mechanism 5, the present device can show excellent performance and strong adaptability during actual use. It can be operated by starting the drive motor 551 on the fixed plate 51. When the drive motor 551 is started, it can drive the transmission gear 553 to rotate. The transmission gear 553 is in a meshing connection state with the gear ring 552. As the transmission gear 553 continues to rotate, the gear ring 552 can be driven to rotate with the help of the transmission gear 553. When the gear ring 552 rotates, it will drive the slip ring 54 to rotate, and the slip ring 54 will drive the slider 53 to slide on the inner side of the annular rail 52. The sliding of the slip ring 54 can drive the various injection mechanisms 6 on its outside to rotate, and then the movable displacement of the injection mechanism 6 can be flexibly adjusted. In this way, it is easy to adjust the position and direction of the injection mechanism 6, so that the present device can flexibly adapt to the injection position of the coolant, greatly improving the overall adaptability of the present device, and providing more accurate and effective cooling support for the processing process of CNC machine tools;

[0028] The provision of the spray mechanism 6 ensures excellent performance during use. The device can be activated by activating the electric push rod 622, which pushes the top ring 623 downward. As the top ring 623 slides, it pushes each rack 624 up and down. The racks 624 are meshed with the drive gear 63. As the top ring 623 drives the racks 624 up and down, they assist in the rotation of the drive gear 63. Rotation of the gears drives the spray pipes 64. Adjusting the rotation of the spray pipes 64 further adjusts the direction of the spray. During operation, the spray pipes 64 not only allow for flexible rotation and adjustment, but also facilitate adjustment of the direction of each spray pipe 64. During operation, the threaded connector 7 connects to an external water supply line. Coolant is then discharged through the water connection pipe 4 into the annular water supply pipe 3. Water in the annular water supply pipe 3 is then supplied to each spray pipe 64. By regulating the opening and closing of the solenoid valve 65, the discharge of water from each injection pipe 64 can be flexibly controlled. This design can greatly improve the overall coolant injection performance of the device and the flexibility during use, providing more efficient and precise cooling services for the processing of CNC machine tools and facilitating the use of the device.
