Description

Technical Field

[0001] This utility model relates to the field of carving technology, specifically a cooling mechanism for a precision carving machine. Background Technology

[0002] A CNC engraving machine is a precision machining equipment primarily used for high-precision engraving, cutting, and milling of various materials. It is typically equipped with a high-precision spindle motor and tool system, enabling high-speed rotation and precise cutting movements. Materials that can be processed include metals, plastics, wood, glass, and jade. CNC engraving machines are widely used in mold manufacturing, handicrafts processing, electronic product manufacturing, advertising production, architectural model making, and many other fields. They can process various complex shapes, patterns, and text to meet the high-precision, high-quality machining needs of different industries.

[0003] Existing CNC engraving machines typically cool by spraying coolant onto the engraving area. The existing spraying device is bolted to one side of the machine, allowing it to move synchronously with the machine during engraving. However, in practice, the coolant cannot be sprayed omnidirectionally, resulting in insufficient cooling of certain areas of the engraving tool and workpiece, leading to frequent localized overheating. Furthermore, the need to change engraving tools of different sizes during engraving makes it difficult for the fixed spraying device to flexibly adjust the spray angle, thus failing to adapt to different shapes and sizes of engraving tasks and reducing the cooling effect during engraving. Therefore, we propose a cooling mechanism for CNC engraving machines. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the coordinated arrangement of a fixed frame, a ball-joint nozzle, a clamping plate, a threaded rod, and a connecting pipe, allows for precise engraving. During the engraving process, the fixed frame is fitted onto the surface of the lower end of the engraving machine body, and the clamping plate is placed against the lower end of the machine body. Twisting the threaded rod inward causes it to move the inner side of the clamping plate box, thus fitting it against the surface of the engraving machine body. This allows for quick and easy fixation of the fixed frame to the machine body. The ball-joint nozzle, with its multi-angle adjustable design, accurately sprays coolant to the critical contact points between the engraving tool and the workpiece, achieving precise cooling and improving the cooling effect during engraving. Furthermore, the connecting pipe's inner cavity is fitted with a filter screen, effectively filtering impurities in the coolant during delivery, preventing nozzle clogging and ensuring the cooling effect remains continuous. This, in turn, improves the precision and efficiency of the engraving process and extends the service life of the engraving tools.

[0014] 2. This utility model uses a liquid storage tank, an assembly slide, and a filter frame to work together to cool the engraved part. After the coolant is cooled, it can flow back into the liquid storage tank and filter the waste liquid through the filter frame, thereby realizing the recycling of coolant and reducing the cost of coolant use. In addition, the filter frame can be easily pulled out in the assembly slide, which is convenient for operators to quickly replace and clean the filter frame later, effectively improving the convenience of use.

A second limiting groove 15 is formed on the inner side wall of the sliding frame 14. A sliding seat 7 is slidably mounted on the surface of the second limiting groove 15. A CNC engraving machine body 8 is detachably connected to the inner side of the sliding seat 7. A cooling component 9 is detachably connected to the lower surface of the CNC engraving machine body 8. A first drive screw 13 and a second drive screw 16 are rotatably connected to one side of the inner cavity of the top frame 6 and the top of the sliding frame 14, respectively. Furthermore, one side of the sliding frame 14 and the top of the sliding seat 7 are respectively threaded to the surfaces of the first drive screw 13 and the second drive screw 16, and one end of the first drive screw 13 and the second drive screw 16 are respectively equipped with a servo drive motor. Through the coordinated cooperation of the liquid storage tank 1, the fixed rod 5, the top frame 6, the sliding frame 14, the sliding seat 7, the drive screw and the servo drive motor, the drive screw can be driven to rotate forward and backward by the servo drive motor during fine carving, thereby realizing the precise and flexible movement of the carving machine body 8 in the front, back and left and right. At the same time, the detachable cooling component 9 can effectively dissipate heat for the carving machine, which not only meets the carving needs of different positions and complex patterns, but also ensures that the carving process is efficient and stable, effectively improving the accuracy and efficiency of carving processing.

[0023] The cooling component 9 includes a fixed frame 91, a ball-joint nozzle 92, a clamping plate 93, a threaded rod 94, a connecting pipe 95, and a suction pipe 96. The fixed frame 91 is detachably fitted onto the lower surface of the engraving machine body 8. Threaded rods 94 are threadedly connected to both sides of the fixed frame 91. The clamping plate 93 is provided inside the threaded rod 94, and the clamping plate 93 is rotatably connected to the inner side of the threaded rod 94 through a rotating connecting shaft. A nesting hole 18 is formed on the lower surface of the fixed frame 91. The inner cavity of the nesting hole 18... A ball-joint type nozzle 92 is rotatably nested. A water passage groove 17 is provided inside the fixing frame 91, and the water passage groove 17 is interconnected with the liquid inlet end of the ball-joint type nozzle 92. A connecting pipe 95 is interconnected on the back of the fixing frame 91. A suction pipe 96 is threadedly connected to the liquid inlet of the connecting pipe 95, and the end of the suction pipe 96 is interconnected with a suction pump matched to the bottom of the inner cavity of the storage tank 1. The connecting pipe 95 includes a pipe body 951, a limiting plate 952, and a filter screen 953. The back of the fixing frame 91 is detachably embedded. A tube body 951 is fitted, and the liquid inlet end of the tube body 951 is threadedly connected to the suction tube 96. A limiting plate 952 is fixedly connected to one side of the inner cavity of the tube body 951, and a filter screen 953 is nested in the inner cavity of the tube body 951 on the outer wall of the limiting plate 952. Through the combination of the fixing frame 91, the threaded rod 94 and the clamping plate 93, quick assembly and disassembly on the engraving machine body 8 can be achieved to adapt to different equipment needs. With the help of the ball joint nozzle 92 (the ball joint nozzle 92 is composed of a ball joint and a nozzle body. The ball joint enables the nozzle body to rotate and swing in multiple directions. It has the advantages of flexible angle adjustment and adaptability to various scenarios. It is widely used in industrial cooling and lubrication, cleaning and spraying, precision irrigation in agriculture and fire extinguishing. This technology is existing technology) the spray angle can be flexibly adjusted to accurately target the heat-generating parts of the engraving, effectively cool down, and when the coolant is delivered for cooling, the filter screen 953 in the connecting tube 95, together with the limiting plate 952, can efficiently filter impurities in the coolant, prevent nozzle blockage, and ensure the stable operation of the cooling system.

[0024] The liquid storage tank 1 has an assembly groove 10 on its upper inner wall. A filter frame 11 is slidably mounted inside the assembly groove 10. A support plate 2 is fixedly connected to the top of the liquid storage tank 1. Electric telescopic rods 4 are nested on the inner walls of the liquid storage tank 1 on both sides above the support plate 2. A positioning plate 3 is detachably connected to the telescopic end of the electric telescopic rod 4, and the bottom end of the positioning plate 3 is attached to the upper surface of the support plate 2. The width of the support plate 2 is smaller than the width of the liquid storage tank 1, and both sides of the support plate 2 are fixedly connected to the inside of the liquid storage tank 1. The liquid storage tank 1 achieves convenient and quick installation and removal of the filter frame 11 through the sliding cooperation between the assembly groove 10 and the filter frame 11. When the filter frame 11 is installed, the electric telescopic rod 4 extends and drives the positioning plate 3 to move towards each other, which can quickly clamp and fix the engraved part on the support plate 2, ensuring its stability during processing and preventing shaking from affecting the engraving effect.

[0025] The liquid storage tank 1 is equipped with a control panel on one side, and the engraving machine body 8 and the electric telescopic rod 4 are electrically connected to an external power source through the control panel. The control panel next to the liquid storage tank 1 enables intelligent control of the engraving machine body 8. The operator only needs to make simple parameter settings and function selections on the control panel to accurately control the operating status of the engraving machine and the extension and retraction of the electric telescopic rod 4, avoiding the cumbersome decentralized control of multiple devices and improving the ease of use of the engraving machine.

[0026] It should be noted that this utility model is a cooling mechanism for a precision engraving machine. During precision engraving, the fixing frame 91 is first fitted onto the lower surface of the engraving machine body 8, so that the clamping plate 93 fits against the lower end of the engraving machine body 8. The threaded rod 94 is twisted inward, which moves the clamping plate 93 and makes it fit tightly against the surface of the engraving machine body 8, completing the quick installation of the fixing frame 91. Then, according to the processing position of the engraving tool and the workpiece, the coolant spray direction is adjusted to the key engraving parts by utilizing the multi-angle free adjustment characteristic of the ball joint nozzle 92. The equipment is then started for precision engraving. During this process, the suction pump in the liquid storage tank 1 draws coolant and delivers it to the fixing frame 91. The coolant is sprayed into the water channel 17 of the frame 91 and directed onto the carving area by the adjusted ball joint nozzle 92, thereby cooling the carving area. During the delivery of coolant, the filter screen 953 in the connecting pipe 95 continuously filters impurities in the coolant, ensuring that the nozzle is not blocked and the cooling effect is stable. At the same time, the coolant generated during the fine carving process flows back to the storage tank 1 and is filtered by the filter frame 11 in the tank, realizing the recycling of coolant. When the filter frame 11 needs to be cleaned or replaced, it can be directly pulled out from the assembly slide 10, which is convenient and quick, ensuring the cooling effect and processing accuracy of fine carving, reducing the cost of coolant use, and improving the ease of operation.
