Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled machine tools, and in particular to a numerically controlled machine tool which is convenient for replacing cutting tools. Background Art

[0002] CNC machine tools are mechatronic products that integrate computer technology, automatic control technology, and precision measurement technology. They control mechanical movement and processing through digital information, and can automatically operate cutting tools to complete complex, precise, small-batch, and multi-variety parts processing tasks.

[0003] CNC machine tool cutting tools are the core components that enable CNC machine tools to achieve high-precision and high-efficiency processing. Their material, type and parameters directly affect the processing quality, efficiency and equipment performance, and are key factors in ensuring the adaptability of production processes and optimizing overall efficiency.

[0004] When replacing cutting tools, existing CNC machine tools are difficult to adapt to cutting tools of different categories or specifications, and most of them are of the same type, which makes it difficult to meet the needs of diversified processing. At the same time, the clamping-type quick assembly method is difficult to ensure the stability and rigidity of the cutting tools after installation. In addition, the cutting tools on the existing tool discs lack pre-use maintenance, resulting in residual chips and impurities on the surface of the cutting tools, increasing the friction between the cutting tools and the workpiece during use, and shortening the service life. With the commonly used maintenance methods, the cutting head is also easily stained with maintenance oil. If used directly, the probability of thermal deformation is increased, and the stability of the processing size and the smoothness of the workpiece surface are reduced. Therefore, the present application provides a CNC machine tool that is easy to replace cutting tools to meet the needs. Summary of the Invention

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up a horizontal and vertical universal sleeve assembly, it can adapt to various types and specifications of cutting tools to meet diversified processing needs. At the same time, it also speeds up the speed and firmness of tool fixing and reduces processing restrictions caused by tool mismatch. At the same time, the flipping method is suitable for horizontal and vertical CNC machine tools, which expands the application range of machine tools and improves the versatility of equipment. In addition, by rotating to adjust the tool holder specifications, tool replacement is more convenient and replacement efficiency is improved. The infrared positioning function can replace the liquid leakage bearing at any time when deviation occurs, thereby improving the accuracy of tool operation. The oil tank not only conveys engine oil but also conveys oil to the leakage bearing to ensure its heat dissipation and lubrication, improves operating efficiency and extends service life. These designs ensure the stability and rigidity of the tool after installation, reduce vibration and errors during processing, and the quick replacement and adaptation functions further reduce the workload of operators and improve work comfort and safety.

[0019] By setting up a maintenance transmission component, an inclined pipe is used to blow air to the tool on the cutter disc to remove chips and impurities on the surface. At the same time, the inclined conveying pipe reduces the impact on the tool and reduces the risk of damage. The conveying of the conveying pipe speeds up the speed and accuracy of tool replacement. The buffer mesh provides secondary protection for the tool during transportation to avoid bumps and slow down the speed to ensure the integrity and performance of the tool. During the transportation process, the spraying of water-soluble cutting curing fluid prevents tool oxidation and maintains the sharpness and processing accuracy of the tool. This design realizes automated cleaning, maintenance and transportation, reduces manual intervention, shortens tool replacement time, and improves production efficiency. At the same time, the automated process also reduces the workload of operators, improves work comfort and safety. In addition, the water-soluble cutting curing fluid treatment enhances the corrosion resistance of the tool, ensures the stability and consistency of the processing process, and also extends the service life of the tool, reduces the replacement frequency, and reduces operating costs.

[0020] By setting up a clamping adjustment component, after the tool is cured by water-soluble cutting fluid, the blade is clamped when it is transported to the outlet, and the hydraulic nozzle sprays and cleans the tool head. At this time, the water-soluble cutting fluid is transformed into a cleaning agent when it meets water, which effectively removes chips, impurities and oil stains on the surface of the tool head to ensure cleanliness. The water flow from the nozzle penetrates into the fine parts and thoroughly cleans them, reducing friction and wear in subsequent processing, extending the tool life, improving the processing dimensional stability and the surface finish of the workpiece, reducing dimensional errors and surface roughness, and the environmentally friendly characteristics of the water-soluble cutting fluid reduce the waste liquid treatment cost, avoid environmental pollution, and ensure the health and safety of operators. This improvement significantly improves the tool management and processing efficiency of CNC machine tools, while reducing operating costs and maintenance difficulty.

[0043] As an implementation method in this embodiment, Figures 3 to 7As shown, the horizontal and vertical universal sleeve assembly 6 includes a connecting rod 61, which is installed at the bottom of the power chamber 10. The bottom of the connecting rod 61 is rotatably connected to a rotating seat 62, one end of the rotating seat 62 is installed with a rotating shaft 63, and one end of the rotating shaft 63 is rotatably connected to a magnetic seat 64. The surface of the magnetic seat 64 is provided with a plurality of protrusions, and one end of the magnetic seat 64 is provided with a magnetic block 65. The surface of the magnetic block 65 is provided with a plurality of grooves corresponding to the protrusions on the surface of the magnetic seat 64. One end of the magnetic block 65 is installed with a tool sleeve 66, which is provided below the connector 5. A support frame 67 is installed at one end, an elastic block 68 is installed on the top of the support frame 67, an oil tank 69 is installed on one side of the support frame 67, a liquid spray pipe 611 is installed at the bottom of the support frame 67, the surface of the tool sleeve 66 is rotatably connected to a liquid leakage bearing 610, the interior of the liquid leakage bearing 610 is provided with micropores, the output end of the oil tank 69 is connected to the internal micropores of the liquid leakage bearing 610, and a positioning probe 612 is installed at the bottom of the liquid leakage bearing 610. First, the length of the horizontal and vertical universal sleeve assembly 6 is adjusted by the connecting rod 61, and then the connecting rod 61 is rotated to drive the rotating seat 62 to rotate. At this time, the rotating seat 6 2 The tool sleeve 66 installed at one end rotates synchronously, so that the tool sleeve 66 corresponding to the tool to be worked 73 rotates to the bottom of the connecting head 5, so that the axis of the tool sleeve 66 and the axis of the connecting head 5 are on the same axis. When the vertical CNC machine tool is operating, the rotating shaft 63 does not rotate, and then the magnetic seat 64 and the magnetic block 65 attract each other and remain fixed. When the magnetic block 65 remains fixed, the tool sleeve 66 at one end of the magnetic block 65 also remains fixed. Then the support frame 67 at one end of the tool sleeve 66 completes the storage of lubricating oil and plays a supporting role at the same time, so that the top of the support frame 67 The elastic block 68 is always ready to contact and fix with the connector 5, and then the oil tank 69 installed on one side of the support frame 67 delivers oil to the spray pipe 611 while also delivering oil to the liquid leakage bearing 610 installed on the tool sleeve 66, thereby reducing the temperature of the liquid leakage bearing 610 when driving the tool 73 to rotate, and improving the lubrication effect of the liquid leakage bearing 610. At the same time, during operation, the positioning probe 612 always transmits data back to the control center 2 to prevent the tool 73 from offset. At the same time, the liquid leakage bearing 610 can be replaced to facilitate the accuracy of the data tool 73 operation.

[0044] As an implementation method in this embodiment, Figures 4 to 11As shown, the maintenance transmission assembly 7 includes a support frame 71, which is mounted on the bottom of the mechanical cabin 9. A cutter disc 72 is mounted on one side of the support frame 71. The cutter disc 72 is arranged in a polygonal shape. A tool 73 is mounted on one end of the cutter disc 72. The bottom of the support frame 71 is rotatably connected to a rotating frame 74. A conveying cylinder 75 is mounted on the bottom of the rotating frame 74. The open end of the conveying cylinder 75 is bent 15 degrees. A bellows 76 is mounted on one end of the conveying cylinder 75. A cutting fluid tank 77 is mounted on the bottom of the conveying cylinder 75. A ring air duct 78 is mounted on the top of the bellows 76. , the annular air duct 78 is arranged inside the open end of the conveying cylinder 75, and an oblique through-tube 79 is installed at one end of the annular air duct 78. A buffer mesh 710 is installed inside the conveying cylinder 75. The buffer mesh 710 is made of polyester mesh. A maintenance nozzle 711 is installed on the inner wall of the conveying cylinder 75. The maintenance nozzle 711 is arranged below the buffer mesh 710. The knife disc 72 at one end of the support frame 71 is rotated to the required tool 73 to the bottom through the control of the control center 2, and then the rotating frame 74 is installed at the bottom of the support frame 71 to rotate. When the rotating frame 74 During the rotation, the conveying cylinder 75 installed at the bottom of the rotating frame 74 moves along with it. When the opening at one end of the conveying cylinder 75 rotates to the bottom of the cutter disc 72, it stops rotating. At this time, the opening of the conveying cylinder 75 is located at the bottom of the cutter disc 72, and then the bellows 76 starts to operate. The wind generated by the bellows 76 during operation is transported to the inclined pipe 79 through the annular air duct 78. The inclined pipe 79 then transports the wind force generated by the bellows 76 to the bottom of the cutter disc 72 through the opening at one end of the conveying cylinder 75. At this time, the wind force blows on the cutter disc 72, and more wind force blows on the bottom of the cutter disc 72. The tool 73 at the bottom is blown to remove impurities and dust on its surface. After blowing for a period of time, the tool 73 at the bottom of the cutter disc 72 is controlled to detach. When the tool 73 detaches, it falls into the inside of the conveying cylinder 75. The inclined conveying cylinder 75 protects and conveys the tool 73. When the tool 73 moves to the middle of the conveying cylinder 75, it contacts the buffer mesh 710. The buffer mesh 710 protects the tool 73 while moving, and its moving speed is slowed down. In the process of moving, the buffer mesh 710 also cleans impurities and dust on the surface of the tool 73. At this time, the cutting fluid tank 77 starts to run, and the water-soluble cutting curing fluid is sprayed onto the surface of the tool 73 through the curing nozzle 711 to maintain the tool 73 during the moving process until the tool 73 moves to the clamping adjustment component 8 and the cutting fluid tank 77 stops running.

[0045] As an implementation method in this embodiment, Figures 8 to 12As shown, the clamping adjustment assembly 8 includes a pipe disc 81, which is composed of a vertical tube and a hollow disc. The pipe disc 81 is installed at one end of the conveying cylinder 75, and one end of the pipe disc 81 is rotatably connected to a tapered tube 82. The inner wall of the tapered tube 82 is installed with a water pressure nozzle 83. One end of the pipe disc 81 is rotatably connected to a turntable 85, which is rotatably installed between the pipe disc 81 and the groove seat 89. One end of the turntable 85 is installed with a hollow frame 84, and one end of the hollow frame 84 is installed with a dial plate 86. The inner sliding connection of the dial plate 86 is a slider 87. One end of the pipe disc 81 is installed with a hydraulic push rod 88, and the output end of the hydraulic push rod 88 is connected to the slider 87. The pipe disc 81 is connected with a groove seat 89 at one end, and a hole is excavated inside the groove seat 89. A baffle is provided at one end of the groove seat 89. The inner sliding connection of the groove seat 89 is provided with a connecting arm 810. A column 811 is installed at one end of the connecting arm 810. A round rod 812 is installed on the surface of the column 811. The round rod 812 is installed at one end of the surface of the column 811. When the tool 73 for maintenance moves to one end of the conveying cylinder 75, the clamping adjustment assembly 8 starts to operate. At this time, the tool 73 moves to the pipe disc 81. At this time, the control center 2 transmits a command to the hydraulic push rod 88, and the hydraulic push rod 88 starts to operate and pushes the slider 8 at the output end. 7 moves, when the slider 87 is pushed by the hydraulic push rod 88, the dial plate 86 moves, and the movement of the dial plate 86 causes the hollow frame 84 installed at one end of the dial plate 86 to rotate. When the hollow frame 84 rotates, the turntable 85 installed at one end of the hollow frame 84 rotates between the groove seat 89 and the tube disc 81. At the same time, the rotation of the hollow frame 84 also drives the round rod 812 to move along with the hollow frame 84, and the movement of the round rod 812 causes the column 811 installed at one end of the round rod 812 to deviate and rotate. Multiple groups of columns 811 rotate synchronously to reduce the internal space. When the column 811 deviates, In the embodiment, the connecting arm 810 installed at one end of the column 811 slides in the groove inside the groove seat 89. At this time, multiple groups of offset columns 811 clamp the blade of the tool 73. When the tool 73 is clamped, the tapered tube 82 rotates. At this time, the rotating tapered tube 82 drives the water pressure nozzle 83 that sprays water to spray water onto the cutting head of the tool 73. When the water source and the water-soluble cutting curing fluid come into contact with each other, the curing fluid begins to react and turns into a cleaning agent to clean the cutting head of the tool 73 until it is dispersed by the water source. The spraying stops, and then the hydraulic push rod 88 is reset, and the column 811 stops clamping the tool 73.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] When using this device, first clean the surface of the workpiece to remove oil, iron filings and dust on the surface of the workpiece, then fix the workpiece on the workbench 3, then set the operating parameters through the control center 2, and then connect the connector 5 at the bottom of the spindle box 4 to the horizontal and vertical universal sleeve assembly 6 to perform the operation.

[0048] When the preparation work is completed, the horizontal universal sleeve assembly 6 is installed at the bottom of the power chamber 10 and connected to it. Then, the length of the horizontal universal sleeve assembly 6 is adjusted by the connecting rod 61, and then the connecting rod 61 is rotated to drive the rotating seat 62 to rotate. At this time, the tool sleeve 66 installed at one end of the rotating seat 62 rotates synchronously, so that the tool sleeve 66 corresponding to the tool 73 to be worked (such as Figure 5 As shown in FIG, the tool sleeve 66 is rotated to the bottom of the connector 5 so that the axis of the tool sleeve 66 is on the same axis as the axis of the connector 5. When the vertical CNC machine tool is in operation, the rotating shaft 63 does not rotate, and then the magnetic seat 64 and the magnetic block 65 attract each other and remain fixed. When the magnetic block 65 remains fixed, the tool sleeve 66 at one end of the magnetic block 65 also remains fixed. Then, the support frame 67 at one end of the tool sleeve 66 completes the storage of lubricating oil, so that the elastic block 68 at the top of the support frame 67 is always ready to contact and fix the connector 5. state, and then the oil tank 69 installed on one side of the support frame 67 not only delivers oil to the spray pipe 611, but also delivers oil to the liquid leakage bearing 610 installed on the tool sleeve 66, thereby reducing the temperature of the liquid leakage bearing 610 when driving the tool 73 to rotate, and improving the lubrication effect of the liquid leakage bearing 610. At the same time, during the operation, the positioning probe 612 always transmits data back to the control center 2 to prevent the tool 73 from deviating. At the same time, the liquid leakage bearing 610 can be replaced, which is convenient for providing data to ensure the accuracy of the tool 73 operation.

[0049] When the workpiece is installed, the maintenance transmission assembly 7 starts to operate, and the cutter disc 72 at one end of the support frame 71 rotates to rotate the tool 73 to be worked to the bottom, and then the rotating frame 74 installed at the bottom of the support frame 71 rotates. When the rotating frame 74 rotates, the conveying cylinder 75 installed at the bottom of the rotating frame 74 moves along with it. When the opening at one end of the conveying cylinder 75 rotates to the bottom of the cutter disc 72, it stops rotating. Figure 8As shown in the figure, at this time, the opening of the conveying cylinder 75 is located at the bottom of the cutter disc 72, and then the bellows 76 starts to operate. The wind generated by the bellows 76 is transported to the inclined pipe 79 through the annular air duct 78. The inclined pipe 79 then transports the wind generated by the bellows 76 to the bottom of the cutter disc 72 through the open end of one end of the conveying cylinder 75. At this time, the wind blows on the cutter disc 72 while also blowing on the cutter 73 at the bottom of the cutter disc 72 to remove impurities and dust on its surface. After the wind blows for a period of time, the cutter 73 at the bottom of the cutter disc 72 is controlled to detach. When the cutter 73 detaches, it falls into the interior of the conveying cylinder 75, and the inclined conveying cylinder 75 protects and conveys the tool 73. When the tool 73 moves to the middle of the conveying cylinder 75, it contacts the buffer mesh 710. The buffer mesh 710 protects the tool 73 while slowing down the movement of the tool 73. During the movement, the buffer mesh 710 also cleans the impurities and dust on the surface of the tool 73. At this time, the cutting fluid tank 77 starts to run, and the water-soluble cutting curing fluid is sprayed onto the surface of the tool 73 through the curing nozzle 711 to maintain the tool 73 during the movement until the tool 73 moves to the clamping adjustment component 8 and the cutting fluid tank 77 stops running.

[0050] When the tool 73 being maintained moves to one end of the conveying cylinder 75, the clamping adjustment assembly 8 starts to operate. At this time, the tool 73 moves to the tube disc 81. Then the control center 2 transmits instructions to the hydraulic push rod 88, the hydraulic push rod 88 starts to operate, and then the output end pushes the slider 87 to move. When the slider 87 is pushed by the hydraulic push rod 88, the dial plate 86 moves. The movement of the dial plate 86 causes the hollow frame 84 installed at one end of the dial plate 86 to rotate. When the hollow frame 84 rotates, the turntable 85 installed at one end of the hollow frame 84 rotates between the groove seat 89 and the tube disc 81. At the same time, the rotation of the hollow frame 84 also drives the round rod 812 to move with the hollow frame 84, and the movement of the round rod 812 causes the column 811 installed at one end of the round rod 812 to offset and rotate. 11 rotates synchronously to reduce the internal space. When the column 811 is offset, the connecting arm 810 installed at one end of the column 811 slides in the groove inside the groove seat 89. At this time, multiple groups of offset columns 811 clamp the blade of the tool 73. When the tool 73 is clamped, the conical tube 82 rotates. At this time, the rotating conical tube 82 drives the water pressure nozzle 83 that sprays water to spray water onto the cutter head of the tool 73. When the water source and the water-soluble cutting curing fluid come into contact with each other, the curing fluid begins to react and turns into a cleaning agent to clean the cutter head of the tool 73 until it is dispersed by the water source and the spraying stops. Then the hydraulic push rod 88 is reset, and the column 811 stops clamping the tool 73. At this time, the tool 73 continues to move under the action of gravity until it slides into the inside of the tool sleeve 66.

[0051] When the tool 73 slides into the inside of the tool sleeve 66, the connecting head 5 contacts the tool sleeve 66. During the contact process, the elastic block 68 connects with the connecting head 5. At the same time, squeezed by the connecting head 5, the magnetic block 65 is separated from the magnetic seat 64. Then the tool 73 starts to operate on the workpiece on the workbench 3. At the same time, the oil in the oil tank 69 lubricates the liquid leakage bearing 610 while also lubricating the tool 73 itself.
