Description

Technical Field

[0001] This utility model relates to the field of engraving machine tool cooling, and in particular to a rapid cooling structure for engraving machine tools. Background Technology

[0002] In modern industrial production, engraving machines are widely used in many fields such as wood processing, metal mold manufacturing, stone carving, and electronic component cutting. During the high-speed operation of the engraving machine's cutting tools, a large amount of heat is generated. If it cannot be cooled in time and effectively, it will lead to a decline in tool performance and a shortened lifespan, and will also affect processing accuracy and product quality. Therefore, the tool cooling structure has become a crucial component of engraving machine equipment.

[0003] However, in some small factories, the cutting tool cooling structure of the engraving machines used in actual use is still insufficient and cannot meet the requirements for efficient cooling.

[0004] Traditional cooling oil is mostly discharged or collected after use and cannot be reused during processing. This leads to the need to add new cooling oil frequently, which is time-consuming and labor-intensive. Although some machines can reuse cooling oil, they are generally filtered through a single-layer filter. This means that while small-pore filters can filter impurities, they are easily clogged by large-sized impurities, while large-pore filters cannot filter small impurities. As a result, the purity of the sprayed coolant is insufficient, affecting the cooling effect and processing quality.

[0005] To address this issue, a rapid tool cooling structure for engraving machines is proposed. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a rapid cooling structure for the cutting tools of an engraving machine, which aims to improve the problem in the prior art where the single-layer filter screen is prone to clogging or incomplete filtration of impurities during cooling oil circulation, thus affecting the cooling effect and processing quality.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a rapid cooling structure for the cutting tool of a carving machine, comprising a support leg, a support frame fixedly connected to the upper surface of the support leg, a support plate fixedly connected to the upper surface of the support frame, a guide rail provided on the upper surface of the support frame, a tool holder provided on the outer wall of the guide rail, a carving tool fixedly installed at the bottom end of the tool holder, and a spray assembly provided at the rear end of the support frame;

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.

[0036] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a rapid cooling structure for the cutting tool of an engraving machine, including a support leg 1 for supporting the overall device, a support frame 2 fixedly connected to the upper surface of the support leg 1, the support frame 2 being square and having a hollow upper surface, a support plate 3 for supporting the workpiece being processed fixedly connected to the upper surface of the support frame 2, a guide rail 4 provided on the upper surface of the support frame 2, a tool holder 5 provided on the outer wall of the guide rail 4, and an engraving knife 6 for grinding the workpiece fixedly installed at the bottom end of the tool holder 5. The guide rail 4, the tool holder 5, and the engraving knife 6 are all prior art and can be implemented by those skilled in the art. Since they are prior art, they will not be described in detail in this case. The guide rail 4 is equipped with a drive device and a control device (not shown in the figure). These components together constitute the engraving machine, which can realize the engraving and cutting function. This part is prior art and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. A spray assembly is provided at the rear end of the support frame 2.

[0037] Reference Figure 2 - Figure 4The spray assembly includes an oil extraction pipe 71, which is used to extract cooling oil from the support frame 2. The oil extraction pipe 71 passes through and is fixedly connected to the rear surface of the support frame 2. An oil outlet pipe 73 is fixedly connected to the end of the oil extraction pipe 71 away from the support frame 2 to discharge oil sludge. When new cooling oil needs to be replaced, it can also be discharged from the oil outlet pipe 73. A pump 72 is installed in the middle section of the oil extraction pipe 71. The pump 72 is prior art and can be implemented by those skilled in the art. The pump 72 is used to extract cooling oil from the support frame... Cooling oil is drawn into the oil extraction pipe 71. A guide pipe 76, a flexible hose, is fixedly connected to the top of the oil outlet pipe 73 to guide the cooling oil. A filter plate 75 is fixedly connected to the top of the inner surface of the oil outlet pipe 73 to filter the cooling oil. The filter plate 75 blocks impurities and oil sludge in the cooling oil, allowing it to pass through. A shut-off valve 74 is installed in the middle section of the oil outlet pipe 73 to block cooling oil and oil sludge. The shut-off valve 74 is existing technology and can be implemented by those skilled in the art. A corrugated pipe 78 is fixedly connected to the end of the pipe 76 away from the oil outlet pipe 73. The corrugated pipe 78 can contract or extend to adapt to different positions of the tool holder 5. A connecting pipe 79 is fixedly connected to the end of the corrugated pipe 78 away from the guide pipe 76. The connecting pipe 79 is a flexible hose. A nozzle 10 is fixedly installed at the end of the connecting pipe 79 away from the corrugated pipe 78. The nozzle 10 can spray cooling oil to cool the tool. Although the angle of the traditional nozzle 10 can be adjusted to align with the engraving tool 6 for precise spraying, this is usually achieved by bending the pipe. The engraving machine will vibrate during actual use. Vibration will cause changes in the curvature of the bending pipe, which will affect the accuracy of the cooling oil spray and the cooling effect, and will not achieve rapid cooling. A support block 8 is fixedly connected to the rear surface of the tool holder 5. An adjustment component is provided on the left surface of the support block 8. The adjustment component can adjust the angle of the nozzle 10 and stabilize the angle of the nozzle 10 to avoid deviation caused by vibration. This can ensure accurate spraying of cooling oil and achieve rapid cooling.

[0038] Reference Figure 2 - Figure 4 The support plate 3 is fixedly connected to the bottom end of the inner surface of the guide rail 4. The inner wall of the bottom end of the support frame 2 is set to be inclined with the front higher and the back lower, which can provide guidance for the cooling oil. The upper surface of the support plate 3 is provided with multiple through slots. The through slots can block large impurities, while the cooling oil and some small impurities can pass through. The multiple through slots are equidistantly distributed in the left and right directions. The rear surface of the guide rail 4 is fixedly connected to a fixing block 77. The guide tube 76 passes through and is fixedly connected to the inner surface of the fixing block 77. The fixing block 77 can provide support for the guide tube 76. The support block 8 is set to L-shape, and the connecting tube 79 passes through and is fixedly connected to the inner surface of the support block 8.

[0039] Reference Figure 2 , Figure 5 , Figure 6The adjustment assembly includes a guide plate 91. The rear end of the right surface of the guide plate 91 is rotatably connected to the left surface of the support block 8. The support block 8 provides support for the guide plate 91. A connecting rod 96 is fixedly connected through the front end of the right surface of the guide plate 91. A screw 93 is threadedly connected through the inner surface of the guide plate 91. A handwheel 92 is fixedly connected to the left end of the screw 93. The outer wall of the handwheel 92 has a recess that fits the contour of the fingers for easy gripping. A locking block 94 is rotatably connected to the right end of the screw 93. A locking groove 95 is formed on the inner surface of the support block 8. The locking block 94 and the locking groove 95 fit together.

[0040] Reference Figure 2 , Figure 5 , Figure 6 The locking block 94 is slidably connected to the right surface of the guide plate 91. The locking block 94 is gear-shaped, and the slot 95 is gear-shaped. The locking block 94 is inserted into the inner wall of the slot 95, which can limit the guide plate 91. The centers of the locking block 94, screw 93, handwheel 92, and slot 95 are all on the same axis. The right surface of the connecting rod 96 is fixedly connected to the left surface of the nozzle 10.

[0041] Working principle: When using the device, first adjust the spray angle of the nozzle 10 according to the model of the engraving knife 6. During adjustment, turn the handwheel 92 to drive the screw 93 to rotate, so that the locking block 94 moves to the left and disengages from the slot 95 to release the limit. Then, turn the guide plate 91 to drive the nozzle 10 to swing and achieve angle adjustment. When the adjustment is complete, hold the guide plate 91 and reverse the handwheel 92 to drive the locking block 94 and the slot 95 to engage, which can ensure the stability of the guide plate 91 and the nozzle 10 and ensure the accurate spraying of subsequent cooling oil.

[0042] After adjustment, place the workpiece on the support plate 3 and start the guide rail 4, tool holder 5, engraving knife 6 and pump 72. After the guide rail 4 and tool holder 5 are started, they can drive the engraving knife 6 to move flexibly. After the engraving knife 6 is started, it will rotate to process the workpiece. When the pump 72 is started, it will draw the cooling oil in the support frame 2 into the oil extraction pipe 71. The cooling oil will pass through the oil extraction pipe 71 and the oil outlet pipe 73. When it flows through the oil outlet pipe 73, it will pass through the filter plate 75. Impurities in the cooling oil will be blocked and accumulate in the oil outlet pipe 73. The cooling oil will flow through the filter plate 75 into the guide pipe 76 and then be sprayed out from the nozzle 10 through the corrugated pipe 78 and the connecting pipe 79 to precisely spray the engraving knife 6 to achieve rapid cooling.

[0043] The sprayed cooling oil will enter the support frame 2 through the through groove on the support plate 3 for recycling. After processing, the guide rail 4, tool holder 5, engraving tool 6 and pump 72 will be turned off, the workpiece will be removed, and then the shut-off valve 74 will be opened to discharge the impurities accumulated in the oil outlet pipe 73.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
