Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and more specifically, to a high-precision numerical control machine tool with good heat dissipation function. Background Technique

[0002] A numerical control machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs specified by control codes or other symbolic instructions. After arithmetic processing, various control signals are sent out by the numerical control device to control the actions of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing.

[0003] When an operator is using a numerical control machine tool to process workpieces, heat will be generated due to the mutual friction between the cutting tool and the workpiece of the machine tool, and heat will also be generated due to the internal transmission friction of the gearbox of the rotating shaft drive of the numerical control machine tool. As a result, heat accumulation will occur inside the numerical control machine tool after continuous operation, causing the temperature inside the numerical control machine tool to continuously rise, leading to the thermal expansion and deformation of some precision components inside the numerical control machine tool, accelerating the wear of the transmission parts, thus affecting the transmission accuracy of the numerical control machine tool. Existing numerical control machine tools often use fans to blow air towards the heat-generating parts to achieve heat dissipation. Although this method can achieve a certain heat dissipation effect, since the fans are often fixedly connected to the numerical control machine tool, the fans can only blow air to a local part of the numerical control machine tool for heat dissipation, resulting in a low heat dissipation effect of the numerical control machine tool and being unable to uniformly and efficiently dissipate heat from the whole numerical control machine tool, bringing inconvenience to the daily use of the operator. Therefore, it needs to be improved. Summary of the Utility Model

Detailed implementation mode

[0029] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 7 shown, the present invention provides a high-precision numerical control machine tool with good heat dissipation function, including:

[0031] The machine housing 1, the inner parts of the top and the left and right sides of the machine housing 1 are fixedly sleeved with the filter screen 2, and the top of the machine housing 1 is fixedly installed with the first limit block 4;

[0032] The driving mechanism is arranged at the top of the machine housing 1;

[0033] The moving mechanism is arranged inside the first limit block 4;

[0034] Among them, the moving mechanism includes a movable frame 5. The outer surface of the bottom end of the movable frame 5 is movably connected with the inside of the first limit block 4. The top of the movable frame 5 is fixedly installed with a first motor 6. The other end of the output shaft of the first motor 6 is fixedly sleeved with a first fan blade 7. Rack 8 is fixedly installed on both the left and right sides of the movable frame 5. The outer surface of the rack 8 is meshed with a gear 9. The inside of the gear 9 is fixedly sleeved with a screw rod 10. The outer surfaces of the top and bottom ends of the screw rod 10 are movably sleeved with fixed plates 11. The outer surface of the fixed plate 11 is fixedly connected with the outer surface of the machine housing 1. The outer surface of the fixed plate 11 is threadedly sleeved with a moving frame 12. The other end of the moving frame 12 is movably connected with a second limit block 13. The outer surface of the second limit block 13 is fixedly connected with the outer surface of the machine housing 1. A second motor 14 is fixedly installed on the outer surface of the moving frame 12. The other end of the output shaft of the second motor 14 is fixedly sleeved with a second fan blade 15.

[0035] When the first motor 6 and the two second motors 14 are running, at this time, the first fan blade 7 and the two second fan blades 15 will rotate. At this time, the first fan blade 7 and the two second fan blades 15 will blow air into the interior of the housing 1 through the three filter screens 2. Due to the limitation of the two first limit blocks 4, the entire movable frame 5 can only move left and right. When the entire movable frame 5 moves left and right repeatedly, at this time, the first fan blade 7 will evenly blow air into the interior of the housing 1 during the left and right movement. At the same time, the two movable frames 5 will drive the two racks 8 to move left and right. Since the two racks 8 are meshed and connected with the two gears 9, when the two racks 8 move left and right, they will drive the two screws 10 to rotate through the two gears 9. Since the two screws 10 are respectively threadedly sleeved with the two movable frames 12, at this time, the two screws 10 will drive the entire two movable frames 12 to move up and down repeatedly during the rotation. At this time, the two second fan blades 15 will evenly blow air into the interior of the housing 1 during the repeated up and down movement.

[0036] Among them, the driving mechanism includes:

[0037] A driving motor 16, the right side of the driving motor 16 is fixedly connected to the top end of the left side of the housing 1, and the other end of the output shaft of the driving motor 16 is fixedly sleeved with a lead screw 17.

[0038] A movable block 18, the interior of which is threadedly sleeved with the outer surface of the lead screw 17. The bottom end of the movable block 18 is movably connected to the top end of the housing 1, and the front surface of the movable block 18 is fixedly connected to the back surface of the movable frame 5.

[0039] When the driving motor 16 is running, at this time, the lead screw 17 will rotate. Since the lead screw 17 is threadedly sleeved with the movable block 18, when the lead screw 17 rotates, it will drive the entire movable frame 5 to move left and right repeatedly through the movable block 18.

[0040] Among them, the bottom end of the housing 1 is fixedly installed with an operating table 19. A limiting groove 21 is opened at the bottom end of the operating table 19, and discharge ports 22 are opened on both the left and right sides of the back surface of the operating table 19.

[0041] Due to the design of the limiting groove 21, the object located inside it will be limited so that it can only move back and forth. Due to the design of the two discharge ports 22, the waste generated during workpiece processing can be discharged to the outside of the operating table 19 through the two discharge ports 22.

[0042] Among them, a numerical control machine tool body 20 is fixedly installed at the top end of the operating table 19, and a base 23 is fixedly installed at the bottom end of the operating table 19.

[0043] Due to the design of the base 23, it will be able to provide a good supporting effect on the entire operating table 19.

[0044] Among them, a fixing frame 24 is fixedly installed at the center of the bottom end of the working table surface 19, and a power motor 25 is fixedly installed at the bottom end of the fixing frame 24. The other end of the output shaft of the power motor 25 is fixedly sleeved with a rotating shaft 26.

[0045] When the power motor 25 operates, the rotating shaft 26 will rotate at this time.

[0046] Among them, a rotating rod 27 is fixedly sleeved at the top end of the rotating shaft 26, and a pressing shaft 28 is fixedly sleeved inside the other end of the rotating rod 27.

[0047] When the rotating shaft 26 rotates, the rotating shaft 26 will drive the pressing shaft 28 to rotate through the rotating rod 27 at this time.

[0048] Among them, a movable rod 29 is movably connected to the outer surface of the pressing shaft 28. The top end of the movable rod 29 is movably connected to the bottom end of the working table surface 19. A push plate 3 is fixedly installed in the middle of the top end of the movable rod 29. The outer surface of the push plate 3 is movably connected to the inside of the working table surface 19. The outer surface of the bottom end of the push plate 3 is movably connected to the inside of the limiting groove 21.

[0049] When the pressing shaft 28 rotates, its outer surface will squeeze the inside of the movable rod 29, causing the movable rod 29 to drive the push plate 3 to move. Due to the limiting effect of the limiting groove 21, the push plate 3 will move backward under the drive of the movable rod 29 at this time. At this time, the push plate 3 will push the waste out of the working table surface 19 during the backward movement.

[0050] The working principle and usage process of the present utility model:

[0051] First, the operator starts the first motor 6 and the two second motors 14 simultaneously. At this time, the first fan blade 7 and the two second fan blades 15 will rotate. Due to the design of the outer shapes of the first fan blade 7 and the two second fan blades 15, when the first fan blade 7 and the two second fan blades 15 rotate, they will be able to blow air into the interior of the housing 1, thereby achieving the effect of cooling the interior of the housing 1. Subsequently, the operator starts the drive motor 16. At this time, the lead screw 17 will rotate. Since the outer surface of the lead screw 17 is threadedly sleeved with the interior of the movable block 18, when the lead screw 17 rotates, it will drive the movable frame 5 to move through the movable block 18. Due to the design of the two first limit blocks 4, the movement of the movable frame 5 will be limited, so that the movable frame 5 can only move left and right. At this time, the entire movable frame 5 will be driven by the movable block 18 to repeatedly move left and right along the interior of the two first limit blocks 4. At this time, the first fan blade 7 will blow air into the interior of the housing 1 evenly during the left and right movement. At the same time, the two racks 8 will be driven by the movable frame 5 to repeatedly move left and right. Since the two racks 8 are respectively meshed and connected with the two gears 9, when the two racks 8 move left and right, they will drive the two gears 9 to rotate. At this time, the two gears 9 will respectively drive the two screw rods 10 to rotate. Since the outer surfaces of the two screw rods 10 are respectively threadedly sleeved with the interiors of the two moving frames 12, when the two screw rods 10 rotate, they will drive the two moving frames 12 to move. Due to the design of the two second limit blocks 13, the movement of the two moving frames 12 will be limited, enabling them to only move up and down. At this time, the entire two moving frames 12 will be driven by the two screw rods 10 to repeatedly move up and down. At this time, the two second fan blades 15 will blow air into the interior of the housing 1 evenly during the up and down movement, thus realizing the function of efficiently and evenly dissipating heat from the numerical control machine tool body 20.

[0052] Subsequently, the operator starts the power motor 25. At this time, the rotating shaft 26 will drive the rotating rod 27 to rotate. At this time, the extrusion shaft 28 will rotate around the rotating shaft 26 driven by the rotating rod 27. During this process, the outer surface of the extrusion shaft 28 will extrude and push the interior of the movable rod 29, so that the movable rod 29 drives the push plate 3 to move. Since the outer surface of the bottom end of the push plate 3 is movably connected with the interior of the limiting groove 21, the push plate 3 can only move back and forth along the interior of the limiting groove 21. At this time, the push plate 3 will be driven by the movable rod 29 to move backward along the interior of the limiting groove 21. At this time, the push plate 3 will push the waste materials inside the working table 19 during the backward movement. Subsequently, these waste materials will be pushed by the push plate 3 to move out of the interior of the working table 19 through the two discharge ports 22, thus realizing the function of automatically cleaning the waste materials inside the working table 19.
