Specific implementation mode

[0011] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0012] A hard rail high-speed cutting machine tool for die-casting machine processing disclosed by the present invention is mainly applied to the scenario where the existing hard rail high-speed cutting machine tool cannot ensure the effective lubrication of the hard rail.

[0013] Referring to Figures 1 - 7 , a hard rail high-speed cutting machine tool for die-casting machine processing, includes a machine tool body 1. A working cavity 2 is opened on the machine tool body 1. A linear motor one 11 and a linear motor two 12 are arranged on the top inner wall of the working cavity 2. The output end of the linear motor one 11 is bolted to the upper side of the linear motor two 12. And a cutting tool head 10 is arranged below the linear motor two 12. A variable-angle cooling module 9 is arranged outside the cutting tool head 10. The bottom inner wall of the working cavity 2 is bolted with a mounting rack 5. Two symmetrical V-shaped rails 6 are bolted to the upper side of the mounting rack 5. The same bearing platform 7 is slidably connected to the two V-shaped rails 6. And two symmetrical circulating oil replenishment modules 8 are arranged outside the mounting rack 5; The circulating oil replenishment module 8 includes an oil delivery pipe 805. A plurality of equally spaced round holes are opened on the oil delivery pipe 805. And an oil bottle 802 is arranged outside the V-shaped rail 6; The variable-angle cooling module 9 includes an infrared camera 906 and a cooling pipe 909.

[0014] Specifically, after placing and fixing the die-casting machine workpiece on the bearing block 7, the second motor 14 operates to make the lead screw 13 push the bearing block 7 to move below the cutter head 10. Then, the folding door 4 is closed, and the first linear motor 11, the second linear motor 12, the second hydraulic rod 15, and the third motor 17 are started. Under the control of the system, the cutter head 10 starts to perform operations such as boring and milling on the workpiece. During the operation, the variable-angle cooling module 9 is used to monitor the temperature of the cutter head 10 and the product processing part and cool it in time. After the processing is completed, the lead screw 13 pushes the bearing block 7 to push the workpiece out of the machine body 1, so that the circulating oil replenishment module 8 can transport the lubricating oil to the V-shaped rail 6. In the next processing link, the part of the bearing block 7 in contact with the V-shaped rail 6 will coat the lubricating oil on the V-shaped surface of the V-shaped rail 6. The device can use the circulating oil replenishment module 8 to perform the oil replenishment operation on the surface of the hard rail during the processing interval of the front and rear workpieces, so as to ensure that there is always a sufficient amount of lubricating oil distributed on the hard rail, greatly slowing down the wear speed of the V-shaped rail 6, ensuring the running quality of the bearing block 7 on the V-shaped rail 6, improving the processing accuracy of the device, delaying the need for scraping, and improving the operating efficiency of the device.

[0015] Refer to Figure 3 , Figure 4 and Figure 5, in a preferred embodiment, two symmetrical placement racks 801 are connected to the inner wall of the bottom of the working chamber 2 by bolts. The inner walls of the two placement racks 801 are respectively inserted with the exteriors of two oil bottles 802. Lower oil grooves 804 and two symmetrical upper oil grooves 803 are formed on both V-shaped rails 6. The lower oil groove 804 is located below the upper oil groove 803, and the inner walls of the lower oil grooves 804 are connected to the exteriors of the oil delivery pipes 805 by bolts; one ends of the two oil delivery pipes 805 close to the oil bottles 802 are connected to the second hoses 810 by bolts. The ends of the second hoses 810 away from the oil delivery pipes 805 all pass through the upper sides of the oil bottles 802 and enter the oil bottles 802. Two symmetrical stabilizing frames 806 are connected to the exterior of the machine tool body 1 by bolts. Fine holes are formed in the stabilizing frames 806, and the first hoses 809 are connected to the interiors of the fine holes by bolts. A lead screw 13 is rotatably connected to the mounting frame 5 by a bearing. A convex seat is arranged on the exterior of the lead screw 13, and the upper side of the convex seat is connected to the bottom of the bearing block 7 by a bolt. A second motor 14 is connected to the inner wall of the bottom of the mounting frame 5 by a bolt. The output end of the second motor 14 is connected to one side of the lead screw 13 by a coupling; one ends of the two first hoses 809 are connected to air bags 807 by bolts, and the other ends all pass through the upper sides of the same-side oil bottles 802 and enter the oil bottles 802. One end of the first hose 809 located in the same oil bottle 802 is above one end of the second hose 810, and one sides of the air bags 807 away from the stabilizing frames 806 are all connected to moving frames 811 by bolts. Slide rails 812 are connected to the moving frames 811 by bolts. The inner walls of the slide rails 812 are all slidably connected to the exteriors of the same-side stabilizing frames 806. Check valves 808 are arranged on the air bags 807; threaded rods 813 are arranged on one sides of the stabilizing frames 806 away from the air bags 807. Grooves are formed in the exteriors of the moving frames 811. The inner walls of the grooves are rotatably connected to the exteriors of the same-side threaded rods 813 by external threads. External gear rings 814 are arranged on the exteriors of the threaded rods 813. One sides of the external gear rings 814 opposite to the exteriors of the moving frames 811 are rotatably connected by bearings. Locking rings 817 are arranged on the exteriors of the external gear rings 814. Rack bars 815 are connected to the inner walls of the locking rings 817 by bolts. The rack bars 815 are all engaged with the external gear rings 814; Guide buckles 816 are all slidably connected to the exteriors of the two locking rings 817. One sides of the guide buckles 816 opposite to the same-side moving frames 811 are connected to the guide buckles 816 by bolts. Two symmetrical first springs 818 are connected to one sides of the guide buckles 816 away from the threaded rods 813. One ends of the first springs 818 away from the guide buckles 816 are connected to the inner walls of the same-side locking rings 817 by bolts. The same second spring 819 is connected to one sides of the moving frames 811 opposite to the stabilizing frames 806 by bolts.

[0016] Specifically, after the workpiece on the bearing block 7 is processed, the second motor 14 is started. The second motor 14 drives the lead screw 13 to rotate, causing the lead screw 13 to push the bearing block 7 to move away from the tool head 10. After the bearing block 7 moves to the edge of the V-shaped rail 6, the part of the bearing block 7 in contact with the V-shaped rail 6 will contact and push the moving frame 811. The moving frame 811 slides on the stabilizing frame 806 under the force, thereby compressing the airbag 807, and causing the air in the airbag 807 to be injected into the oil bottle 802 through the first hose 809. This increases the air pressure in the oil bottle 802 and pushes the hydraulic oil in the oil bottle 802 to flow into the oil delivery pipe 805 through the second hose 810 and then into the lower oil tank 804 through the round holes on the oil delivery pipe 805. After a new workpiece is fixed on the bearing block 7, the second motor 14 is started again, enabling the bearing block 7 to slide along the V-shaped rail 6, so that the lubricating oil can be distributed to the contact surface along with the movement of the bearing block 7. At the same time, under the action of the check valve 808 and the second spring 819, the airbag 807 drives the moving frame 811 to reset. When the amount of supplementary oil needs to be adjusted, the locking ring 817 is pushed against the elastic force of the spring 818, so that the rack 815 releases the locking of the first external gear ring 814, and the threaded rod 813 is rotated, causing the threaded rod 813 to drive the moving frame 811 to move on the slide rail 812, thereby controlling the air volume in the airbag 807.

[0017] In a specific application scenario, the circulating oil replenishment module 8 is mainly applicable to the circulating oil replenishment link in the circulating oil replenishment process, that is, the circulating oil replenishment module 8 uses the airbag 807 and the oil bottle 802 to enable the device to perform oil replenishment operations during the interval of workpiece replacement processing, so as not to occupy the processing and running time of the die-casting machine workpiece, improving the smoothness of the device operation and the operating efficiency; using the threaded rod 813 and the locking ring 817 enables the device to change the moving distance of the moving frame 811, thereby changing the amount of lubricating oil injected into the oil delivery pipe 805 by the oil bottle 802 each time, so that the device can be applicable to V-shaped rails 6 of different sizes.

[0018] Refer to Figure 6 and Figure 7, in a preferred embodiment, the output end of the linear motor II 12 is bolted to the hydraulic rod II 15, the output end of the hydraulic rod II 15 is bolted to the load-bearing frame 16, the top inner wall of the load-bearing frame 16 is bolted to the motor III 17, the output end of the motor III 17 is bolted to the upper side of the cutter head 10, and an installation ring 901 is bolted to the outside of the load-bearing frame 16; the outside of the installation ring 901 is slidably connected to a movable frame 903, an annular groove is formed in the outside of the installation ring 901, an external gear ring II 902 is bolted in the annular groove, and the upper side of the movable frame 903 is bolted to the motor I 905. The output end of the motor I 905 passes through the movable frame 903 and is connected to a gear 904 through a coupling. The gear 904 meshes with the external gear ring II 902; the cooling pipe 909 is located outside the movable frame 903, and the outside of the cooling pipe 909 is rotatably connected to a fixed frame 907 through a bearing. The side of the fixed frame 907 opposite to the movable frame 903 is bolted, and a pump 910 is bolted to the outside of the movable frame 903. The output end of the pump 910 is connected to the cooling pipe 909 through a conduit. An observation window 3 and a folding door 4 are provided on the machine tool body 1; the outside of the movable frame 903 is rotatably connected to a hydraulic rod I 908 through a bearing, and the output end of the hydraulic rod I 908 is rotatably connected to the outside of the cooling pipe 909 through a bearing. The hydraulic rod I 908 is located below the fixed frame 907, and the upper side of the infrared camera 906 is bolted to the bottom of the movable frame 903.

[0019] Specifically, during the process of the cutter head 10 machining the workpiece, the motor I 905 is started. The motor I 905 drives the gear 904 meshing with the external gear ring II 902 to rotate, so that the movable frame 903 makes a circular motion on the installation ring 901. The infrared camera 906 will monitor the temperature of the contact surface between the cutter head 10 and the workpiece, and start the pump 910 to spray the coolant through the cooling pipe 909 to the machining area. When the temperature at the machining position is too high, the movable frame 903 moves above this area on the installation ring 901, and the hydraulic rod I 908 is started. The output end of the hydraulic rod I 908 pushes the cooling pipe 909 to change the angle, so that the cooling pipe 909 is aligned with the high-temperature area, and the output power of the pump 910 is increased to increase the flow rate of the coolant to cool down the machining position.

[0020] In a specific application scenario, the variable-angle cooling module 9 is mainly applicable to the variable-angle cooling link in the variable-angle cooling process, that is, the variable-angle cooling module 9 can use the infrared camera 906 to enable the device to monitor the temperature of the machining part of the cutter head 10 in real time. The movable frame 903 and the hydraulic rod I 908 can be used to accurately locate the part with too high temperature, so that the cooling pipe 909 can increase the coolant flow rate to cool the workpiece and the cutter head 10 in time, reduce the temperature stress on the workpiece and the cutter head 10, and improve the service life of the cutter head 10.

[0021] Working principle: After placing and fixing the workpiece of the die-casting machine on the bearing platform 7, the second motor 14 operates to make the lead screw 13 push the bearing platform 7 to move below the cutter head 10. Then, the folding door 4 is closed, and the first linear motor 11, the second linear motor 12, the second hydraulic rod 15, and the third motor 17 are started. Under the control of the system, the cutter head 10 starts to perform operations such as boring and milling the workpiece. During the operation, when the cutter head 10 processes the workpiece, the first motor 905 is started. The first motor 905 drives the gear 904 meshing with the second external gear ring 902 to rotate, so that the movable frame 903 makes a circular motion on the mounting ring 901. The infrared camera 906 will monitor the temperature of the contact surface between the cutter head 10 and the workpiece, and start the pump 910 to spray the coolant through the cooling pipe 909 towards the machining area. When the temperature at the machining position is too high, the movable frame 903 moves above this area on the mounting ring 901, and the first hydraulic rod 908 is started. The output end of the first hydraulic rod 908 pushes the cooling pipe 909 to change the angle, so that the cooling pipe 909 is aligned with the high-temperature area. The output power of the pump 910 is increased to increase the flow rate of the coolant and cool down the machining position. After the machining is completed, the lead screw 13 pushes the bearing platform 7 to push the workpiece out of the machine body 1. After the workpiece on the bearing platform 7 is machined, the second motor 14 is started. The second motor 14 drives the lead screw 13 to rotate, so that the lead screw 13 pushes the bearing platform 7 to move away from the cutter head 10. After the bearing platform 7 moves to the edge of the V-shaped rail 6, the part of the bearing platform 7 in contact with the V-shaped rail 6 will contact and push the movable frame 811. The movable frame 811 slides on the stabilizing frame 806 under the force, so as to compress the airbag 807, and the air in the airbag 807 is injected into the oil bottle 802 through the first hose 809, increasing the air pressure in the oil bottle 802 and pushing the hydraulic oil in the oil bottle 802 to flow into the oil delivery pipe 805 through the second hose 810 and flow into the lower oil tank 804 through the round holes on the oil delivery pipe 805. After a new workpiece is fixed on the bearing platform 7, the second motor 14 is started again, so that the bearing platform 7 can slide along the V-shaped rail 6, enabling the lubricating oil to be distributed to the contact surface along with the movement of the bearing platform 7. At the same time, under the action of the check valve 808 and the second spring 819, the airbag 807 drives the movable frame 811 to reset. When it is necessary to adjust the oil supply amount, the locking ring 817 is pushed against the elastic force of the spring 818 to unlock the rack 815 from the first external gear ring 814, and the threaded rod 813 is rotated. The threaded rod 813 drives the movable frame 811 to move on the slide rail 812, thereby controlling the air capacity in the airbag 807.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
