Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machine tools, and particularly relates to a numerical control machine tool that is convenient for tool replacement. Background Art

[0002] A numerical control machine tool is a mechatronic product integrating computer technology, automatic control technology, and precision measurement technology. It controls mechanical motion and the machining process through digital information and can automatically operate tools to complete the machining tasks of complex, precise, small-batch, and multi-variety parts.

[0003] The cutting tool of a numerical control machine tool is the core component for achieving high-precision and high-efficiency machining. Its material, type, and parameters directly affect machining quality, efficiency, and equipment performance, and are the key factors for ensuring production process adaptability and optimizing overall efficiency.

[0004] When replacing tools on existing numerical control machine tools, it is difficult to adapt to different categories or specifications of tools, mainly using the same type of tools, which is difficult to meet the needs of diversified machining. At the same time, the clamping-type quick assembly method is difficult to ensure the stability and rigidity design after tool installation. In addition, the tools on the existing tool disc lack pre-use maintenance, resulting in chips and impurities remaining on the tool surface, increasing the friction between the tool and the workpiece during use, shortening the service life. In the common maintenance method, the tool tip is also easily stained with maintenance oil. If used directly, it increases the probability of thermal deformation, reduces the stability of machining dimensions, and the surface finish of the workpiece. Therefore, the present application provides a numerical control machine tool that is convenient for tool replacement to meet the needs. Summary of the Invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting the horizontal and vertical universal socket assembly, various types and specifications of tools can be adapted to meet diverse processing requirements. At the same time, it also speeds up the speed and firmness of tool fixation, reduces processing limitations caused by tool mismatch. Meanwhile, the flipping method is applicable to horizontal and vertical CNC machine tools, expanding the application range of the machine tool and enhancing the versatility of the equipment. In addition, by rotating and adjusting the tool holder specifications, tool replacement is made more convenient, improving the replacement efficiency. The infrared positioning function can replace the liquid leakage bearing at any time when there is a deviation, improving the accuracy of tool operation. The oil tank conveys oil while also conveying oil to the leakage bearing to ensure its heat dissipation and lubrication, improving the operating efficiency and extending the service life. These designs ensure the stability and rigidity after tool installation, reduce vibration and errors during processing, and the quick replacement and adaptation functions further reduce the workload of operators, enhancing work comfort and safety.

[0017] By setting up a maintenance transmission component, the tools on the cutter head are blown by an inclined through-pipe to remove chips and impurities on the surface. At the same time, the inclined conveying pipe reduces the impact on the tools, lowering the risk of damage. Moreover, the conveying of the conveying pipe speeds up the speed and accuracy of tool replacement. The buffer mesh gauze provides secondary protection for the tools during the conveying process to avoid bumping, and at the same time decelerates to ensure the integrity and performance of the tools. During the conveying process, the spraying of the water-soluble cutting maintenance liquid prevents tool oxidation, maintains the sharpness and machining accuracy of the tools. This design realizes automated cleaning, maintenance, and conveying, reduces manual intervention, shortens the tool replacement time, and improves production efficiency. At the same time, the automated process also reduces the workload of operators, enhances work comfort and safety. In addition, the treatment of the water-soluble cutting maintenance liquid enhances the corrosion resistance of the tools, ensures the stability and consistency of the machining process, also extends the tool service life, reduces the replacement frequency, and lowers the operating cost.

[0018] By setting up a clamping and adjusting component, when the tool is conveyed to the outlet after being maintained by the water-soluble cutting fluid, the tool body is clamped, and the water pressure nozzle sprays and cleans the tool head. At this time, the water-soluble cutting fluid turns into a cleaning agent when encountering water, effectively removing chips, impurities, and oil stains on the surface of the tool head, ensuring cleanliness. The water flow of the nozzle penetrates into fine parts for thorough cleaning, reducing friction and wear in subsequent processing, extending the tool life, improving the machining dimension stability and the surface finish of the workpiece, reducing dimensional errors and surface roughness. And the environmental protection 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 enhances the tool management and machining efficiency of the CNC machine tool, while reducing the operating cost and maintenance difficulty.

[0028] As Figures 1 to 12As shown in the figure, an embodiment of the present invention provides a numerical control machine tool that facilitates tool replacement, including a machine body 1. A control center 2 is installed at one end of the machine body 1. A base 11 is installed at the bottom of the machine body 1. A workbench 3 is installed on the top of the base 11. A spindle box 4 is installed on the top of the machine body 1. A connector 5 is installed at the bottom of the spindle box 4. A mechanical cabin 9 is installed on one side of the spindle box 4. A power chamber 10 is installed at one end of the spindle box 4; a universal horizontal and vertical socket assembly 6 is installed at the bottom of the power chamber 10, and the universal horizontal and vertical socket assembly 6 is used for installing and using different tools 73; a maintenance transmission assembly 7 is installed at the bottom of the mechanical cabin 9, and the maintenance transmission assembly 7 is used for maintaining the tools 73 on the tool disc 72 and conveying them into the universal horizontal and vertical socket assembly 6; a clamping and adjusting assembly 8 is installed at one end of the maintenance transmission assembly 7, and the clamping and adjusting assembly 8 is used for cleaning the tool tips of the maintained tools 73 before operation; the universal horizontal and vertical socket assembly 6 is installed at one end of the maintenance transmission assembly 7, and the maintenance transmission assembly 7 is installed at one end of the clamping and adjusting assembly 8.

[0029] As an implementation method in this embodiment, as Figures 3 to 7As shown, the universal horizontal and vertical socket assembly 6 includes a connecting rod 61. The connecting rod 61 is installed at the bottom of the power chamber 10. A rotating seat 62 is rotatably connected to the bottom of the connecting rod 61. One end of the rotating seat 62 is provided with a rotating shaft 63. One end of the rotating shaft 63 is rotatably connected to a magnetic attraction seat 64. Multiple protrusions are provided on the surface of the magnetic attraction seat 64. One end of the magnetic attraction seat 64 is provided with a magnetic block 65. Multiple grooves are provided on the surface of the magnetic block 65 and correspond to the protrusions on the surface of the magnetic attraction seat 64. A tool sleeve 66 is installed at one end of the magnetic block 65. The tool sleeve 66 is arranged below the connector 5. A support frame 67 is installed at one end of the tool sleeve 66. An elastic clamping block 68 is installed at the top of the support frame 67. An oil tank 69 is installed on one side of the support frame 67. A liquid spraying pipe 611 is installed at the bottom of the support frame 67. A liquid leakage bearing 610 is rotatably connected to the surface of the tool sleeve 66. Micropores are provided inside the liquid leakage bearing 610. The output end of the oil tank 69 is connected to the internal micropores of the liquid leakage bearing 610. A positioning probe 612 is installed at the bottom of the liquid leakage bearing 610. First, adjust the length of the universal horizontal and vertical socket assembly 6 through the connecting rod 61, and then rotate the connecting rod 61 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 operated rotates to the bottom of the connector 5, making the axis of the tool sleeve 66 and the axis of the connector 5 on the same axis. When performing vertical CNC machine tool operations, the rotating shaft 63 does not rotate. Then, the magnetic attraction 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, at the same time, plays a supporting role, so that the elastic clamping block 68 at the top of the support frame 67 is always ready to contact and fix with the connector 5. Then, while the oil tank 69 installed on one side of the support frame 67 conveys oil to the liquid spraying pipe 611, it also conveys oil to the liquid leakage bearing 610 installed on the tool sleeve 66, reducing the temperature when the liquid leakage bearing 610 drives 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 deviating. At the same time, the liquid leakage bearing 610 can be replaced, which is convenient for providing the accuracy of the tool 73 operation.

[0030] As an implementation method in this embodiment, as Figures 4 to 11As shown in the figure, the maintenance transmission assembly 7 includes a support frame 71, which is installed at the bottom of the machine cabin 9. A cutter head 72 is installed on one side of the support frame 71. The cutter head 72 is set to be polygonal. A cutter 73 is installed at one end of the cutter head 72. The bottom of the support frame 71 is rotatably connected to a rotating frame 74. A conveying cylinder 75 is installed at the bottom of the rotating frame 74. The opening end of the conveying cylinder 75 is bent by 15 degrees. An air box 76 is installed at one end of the conveying cylinder 75. A cutting fluid tank 77 is installed at the bottom of the conveying cylinder 75. A ring air duct 78 is installed on the top of the air box 76. The ring air duct 78 is arranged inside the opening end of the conveying cylinder 75. An inclined through pipe 79 is installed at one end of the ring 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 spray head 711 is installed on the inner wall of the conveying cylinder 75. The maintenance spray head 711 is arranged below the buffer mesh 710. The cutter head 72 at one end of the support frame 71 rotates to the required cutter 73 to the bottom through the control of the control center 2. Then, the rotating frame 74 is installed at the bottom of the support frame 71 for rotation. When the rotating frame 74 rotates, the conveying cylinder 75 installed at the bottom of the rotating frame 74 moves accordingly. When the opening end of the conveying cylinder 75 rotates to the bottom of the cutter head 72, the rotation stops. At this time, the opening of the conveying cylinder 75 is located at the bottom of the cutter head 72. Then, the air box 76 starts to operate. The air generated during the operation of the air box 76 is conveyed to the inclined through pipe 79 through the ring air duct 78. The inclined through pipe 79 conveys the wind generated by the air box 76 through the opening at one end of the conveying cylinder 75 to the bottom of the cutter head 72. At this time, while the wind blows the cutter head 72, more wind blows the cutter 73 at the bottom of the cutter head 72 to remove impurities and dust on its surface. After blowing for a period of time, the cutter 73 at the bottom of the cutter head 72 is controlled to disengage. When the cutter 73 disengages, it falls into the interior of the conveying cylinder 75. The inclined conveying cylinder 75 protects and conveys the cutter 73. When the cutter 73 moves to the middle of the conveying cylinder 75 and contacts the buffer mesh 710, the buffer mesh 710 protects and moves the cutter 73 while also slowing down its moving speed. And during the moving process, the buffer mesh 710 also cleans the impurities and dust on the surface of the cutter 73. At this time, the cutting fluid tank 77 starts to operate, spraying the water-soluble cutting maintenance fluid onto the surface of the cutter 73 through the maintenance spray head 711 to maintain the cutter 73 during the moving process until the cutter 73 moves to the clamping and adjusting assembly 8 and then the cutting fluid tank 77 stops operating.

[0031] As an implementation mode in this embodiment, as Figures 8 to 12As shown in the figure, the clamping and adjusting assembly 8 includes a pipe disc 81, which is composed of a vertical pipe and a hollow disc. The pipe disc 81 is installed at one end of the conveying cylinder 75. One end of the pipe disc 81 is rotatably connected to a conical pipe 82, and a water pressure nozzle 83 is installed on the inner wall of the conical pipe 82. One end of the pipe disc 81 is rotatably connected to a turntable 85, and the turntable 85 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, one end of the hollow frame 84 is installed with a dial 86, and a slider 87 is slidably connected inside the dial 86. 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. One end of the pipe disc 81 is installed with a groove seat 89, a hole is dug inside the groove seat 89, a baffle is arranged at one end of the groove seat 89, and a connecting arm 810 is slidably connected inside the groove seat 89. One end of the connecting arm 810 is installed with a column 811, and 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 to be maintained moves to one end of the conveying cylinder 75, the clamping and adjusting assembly 8 starts to operate. At this time, the tool 73 moves to the pipe disc 81. At this time, the control center 2 sends an instruction to the hydraulic push rod 88, and the hydraulic push rod 88 starts to operate and the output end pushes the slider 87 to move. When the slider 87 is pushed by the hydraulic push rod 88, the dial 86 moves. The movement of the dial 86 causes the hollow frame 84 installed at one end of the dial 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 pipe disc 81. At the same time, the rotation of the hollow frame 84 also drives the round rod 812 to move together with the hollow frame 84. The movement of the round rod 812 causes the column 811 installed at one end of the round rod 812 to deflect and rotate. Multiple columns 811 rotate synchronously to reduce the internal space. When the column 811 deflects, 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 deflected columns 811 clamp the blade body of the tool 73. When the tool 73 is clamped, the conical pipe 82 rotates. At this time, the rotating conical pipe 82 drives the water pressure nozzle 83 that sprays water to spray water onto the tool head of the tool 73. When the water contacts the water-soluble cutting maintenance liquid, the reaction starts and the maintenance liquid becomes a cleaning agent to clean the tool head of the tool 73. After being washed away by the water, the spraying stops, and then the hydraulic push rod 88 resets, and the column 811 stops clamping the tool 73.

[0032] The working principle of the technical solution provided by the present invention is as follows: When using this device, first clean the surface of the workpiece to remove the oil, iron filings and dust on the surface of the workpiece, then fix the workpiece on the workbench 3, then set the operation parameters through the control center 2, and then connect the connecting head 5 at the bottom of the main spindle box 4 to the horizontal-vertical universal socket assembly 6 for operation.

[0033] When the preparation work is completed, install the universal horizontal and vertical socket assembly 6 at the bottom of the power chamber 10 and connect it thereto. Then, adjust the length of the universal horizontal and vertical socket assembly 6 through the connecting rod 61, and then rotate the connecting rod 61 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 operated, (as Figure 5 shown) rotates to the bottom of the connector 5, so that the axis of the tool sleeve 66 and the axis of the connector 5 are on the same axis. When performing vertical CNC machine tool operations, the rotating shaft 63 does not rotate. Then, the magnetic suction seat 64 and the magnet 65 attract each other and remain fixed. When the magnet 65 remains fixed, the tool sleeve 66 at one end of the magnet 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 clamping block 68 at the top of the support frame 67 is always ready to contact and fix with the connector 5. Then, while the oil tank 69 installed on one side of the support frame 67 conveys oil to the liquid spraying pipe 611, it also conveys oil to the liquid leakage bearing 610 installed on the tool sleeve 66, reducing the temperature when the liquid leakage bearing 610 drives the tool 73 to rotate and improving the lubrication effect of the liquid leakage bearing 610. At the same time, during the operation process, the positioning probe 612 continuously transmits data back to the control center 2 to prevent the tool 73 from shifting. At the same time, the liquid leakage bearing 610 can be replaced, which is convenient for providing the accuracy of the tool 73 operation.

[0034] When the workpiece is installed, the maintenance transmission assembly 7 starts to operate. The cutter head 72 at one end of the support frame 71 rotates to rotate the tool 73 to be operated to the bottom. 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 accordingly. When one end opening of the conveying cylinder 75 rotates to the bottom of the cutter head 72, it stops rotating, (as Figure 8At this time (as shown), the opening of the conveying cylinder 75 is located at the bottom of the cutter head 72. Subsequently, the air box 76 starts to operate. The air generated during the operation of the air box 76 is conveyed to the inclined pipe 79 through the annular air pipe 78. The inclined pipe 79 then conveys the wind generated by the air box 76 to the bottom of the cutter head 72 through the opening at one end of the conveying cylinder 75. At this time, while the wind blows the cutter head 72, it also blows the cutting tool 73 at the bottom of the cutter head 72 to remove impurities and dust on its surface. After the wind blows for a period of time, the cutting tool 73 at the bottom of the cutter head 72 is controlled to disengage. When the cutting tool 73 disengages, it falls into the interior of the conveying cylinder 75. The inclined conveying cylinder 75 protects and conveys the cutting tool 73. When the cutting tool 73 moves to the middle of the conveying cylinder 75, it contacts the buffer mesh 710. The buffer mesh 710 protects the movement of the cutting tool 73 while also slowing down the moving speed of the cutting tool 73. And during the movement, the buffer mesh 710 also cleans the impurities and dust on the surface of the cutting tool 73. At this time, the cutting fluid tank 77 starts to operate, spraying the water-soluble cutting maintenance fluid onto the surface of the cutting tool 73 through the maintenance nozzle 711 to maintain the cutting tool 73 during its movement until the cutting tool 73 moves to the clamping and adjusting assembly 8 and then the cutting fluid tank 77 stops operating.

[0035] When the maintained cutting tool 73 moves to one end of the conveying cylinder 75, the clamping and adjusting assembly 8 starts to operate. At this time, the cutting tool 73 moves to the pipe plate 81. Subsequently, the control center 2 sends a command to the hydraulic push rod 88, and the hydraulic push rod 88 starts to operate. 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 pipe plate 81. At the same time, the rotation of the hollow frame 84 also drives the round rod 812 to move together with the hollow frame 84. The movement of the round rod 812 causes the cylinder 811 installed at one end of the round rod 812 to offset and rotate. Multiple groups of cylinders 811 rotate synchronously to reduce the internal space. When the cylinder 811 offsets, the connecting arm 810 installed at one end of the cylinder 811 slides in the groove inside the groove seat 89. At this time, multiple groups of offset cylinders 811 clamp the blade body of the cutting tool 73. When the cutting tool 73 is clamped, the tapered pipe 82 rotates. At this time, the rotating tapered pipe 82 drives the water pressure nozzle 83 for spraying water source to spray water source onto the cutting head of the cutting tool 73. When the water source contacts the water-soluble cutting maintenance fluid, the reaction causes the maintenance fluid to become a cleaning agent to clean the cutting head of the cutting tool 73 until it is washed away by the water source and then stops spraying. Then the hydraulic push rod 88 resets, and the cylinder 811 stops clamping the cutting tool 73. At this time, the cutting tool 73 continues to move under the action of gravity until it slides into the interior of the tool sleeve 66.

[0036] When the tool 73 slides into the interior of the tool sleeve 66, the connector 5 comes into contact with the tool sleeve 66. During the contact process, the elastic latch 68 is connected to the connector 5. At the same time, under the extrusion of the connector 5, the magnet 65 is separated from the magnetic seat 64. Then, the tool 73 starts to operate on the workpiece on the workbench 3. Meanwhile, the oil in the oil tank 69 lubricates the liquid leakage bearing 610 and also lubricates the tool 73 itself.
