Description

Technical Field

[0001] This invention relates to the field of machinery, and more particularly to a large saw blade C-axis structure and a cutting machine. Background Technology

[0002] In the field of CNC machine tools, the C-axis usually refers to the coordinate axis that rotates around the Z-axis of the machine tool, and it is a type of rotary axis.

[0003] A five-axis cutting machine is a type of CNC machine tool. In current technology, the C-axis mechanism of a five-axis cutting machine is generally mounted on a C-axis mounting base under the lifting slide or lifting beam. This mounting method is relatively simple and easy to manufacture, and therefore widely used in the industry. For small saw blades, the existing C-axis mechanism is generally sufficient for cutting on a five-axis cutting machine. However, for large saw blades, the existing C-axis mechanism has stability issues. Large saw blades, such as those with a diameter of 1600mm, are large in size, and even slight deviations during cutting can severely affect accuracy, thus requiring high stability. Traditional C-axis mechanisms have very short drive shafts, which cause the entire machine to wobble when subjected to vibration, affecting accuracy when large saw blades are cutting at high speeds.

[0004] Therefore, how to improve existing C-axis mechanisms or cutting machines to solve the above problems has become an important technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This invention discloses a large saw blade C-axis structure and a cutting machine. By setting a C-axis running from top to bottom inside a hollow lifting column, the forward tilt of the center of gravity can be reduced by placing the C-axis in the middle of the hollow lifting column. On the other hand, the design of the long C-axis can buffer vibration and make the transmission more stable, which can solve the problems existing in the prior art.

[0006] The large saw blade C-axis structure provided by the present invention is used in a cutting machine. The cutting machine includes a movable crossbeam, a lifting mounting base, a lifting power source, a lifting column, a C-axis power source, a C-axis, and a saw blade assembly mounted on the movable crossbeam. The lifting mounting base is equipped with a movable lifting column; The lifting power is used to control the longitudinal position of the lifting column on the lifting mounting base; The lifting column is hollow inside, and C-axis power and saw blade assemblies are respectively installed at both ends; C-axis power is used to drive the rotation of the C-axis; The C-axis runs through the interior of the lifting column, with one end connected to the output end of the C-axis power and the other end fixedly connected to the saw blade assembly.

[0007] Preferred, The lifting column is equipped with a slide rail on the outside, and the lifting mounting base is equipped with a slider that cooperates with the slide rail.

[0008] Preferred, The lifting column is equipped with a drive rack; The output end of the lifting power is equipped with a gear that meshes with the drive rack.

[0009] Preferred, The C-axis is set in the exact center of the lifting column.

[0010] Preferred, One end of the C-axis is connected to the output end of the C-axis power via a C-axis reducer, and a bearing is fitted on the other end. The C-axis reducer and the bearing are respectively installed at both ends of the lifting column.

[0011] Preferred, The C-axis is hollow inside and has cable entry / exit holes at the top. The connecting cable for the saw blade assembly enters from the bottom of the C-axis and extends from the cable inlet / outlet port.

[0012] Preferred, The lifting column has a hollow rectangular structure.

[0013] Preferred, The saw blade assembly includes a cutter head holder, a saw blade electric spindle, an electric spindle drive motor, and a saw blade; The tool holder is mounted on the C-axis; The saw blade electric spindle is mounted on the cutter head holder and is driven to rotate by the electric spindle rotation motor; The saw blade is installed at the output end of the saw blade electric spindle; The rotation center line of the saw blade electric spindle is perpendicular to the rotation center line of the C-axis.

[0014] The present invention also discloses a cutting machine, including a frame and a movable crossbeam, including the above-mentioned large saw blade C-axis structure; The lifting mounting base in the C-axis structure of the large saw blade is movably mounted on the moving crossbeam.

[0016] The large saw blade C-axis structure of the present invention is used in a cutting machine. The cutting machine includes a movable crossbeam, a lifting mounting base, a lifting power source, a lifting column, a C-axis power source, a C-axis, and a saw blade assembly mounted on the movable crossbeam.

Detailed Implementation

[0019] This invention discloses a large saw blade C-axis structure and a cutting machine. By setting a C-axis 5 that runs from top to bottom inside the hollow lifting column 3, the forward tilt of the center of gravity can be reduced by placing the C-axis 5 in the middle of the hollow lifting column 3. On the other hand, the design of the long C-axis can buffer vibration and make the transmission more stable, which can solve the problems existing in the prior art.

[0020] The technical solutions of the embodiments of the present invention will be clearly and thoroughly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Please refer to... Figure 1 and 2 The present invention provides a large saw blade C-axis structure for use in a cutting machine. The cutting machine includes a movable crossbeam, and includes a lifting mounting base 1, a lifting power source 2, a lifting column 3, a C-axis power source 4, a C-axis 5, and a saw blade assembly 6 mounted on the movable crossbeam. The lifting mounting base 1 is equipped with a movable lifting column 3; The lifting power 2 is used to control the longitudinal position of the lifting column 3 on the lifting mounting base 1; The lifting column 3 is hollow inside, and its two ends are respectively equipped with C-axis power 4 and saw blade assembly 6; C-axis power 4 is used to drive the rotation of C-axis 5; C-axis 5 runs through the interior of lifting column 3, with one end connected to the output end of C-axis power 4 and the other end fixedly connected to saw blade assembly 6.

[0021] In this invention, the lifting mounting base 1 is installed on the moving crossbeam and can generally move on the moving crossbeam. The cross-section of the lifting mounting base 1 can be a flat-bottomed U-shaped structure, that is, it includes a bottom surface and two side surfaces perpendicular to the bottom surface. In order to ensure the strength of the side surfaces, multiple reinforcing blocks can also be set on the side surfaces. The lifting column 3 is installed on the lifting mounting base 1 through a sliding member. During operation, the lifting power 2 controls the longitudinal position of the lifting column 3 on the lifting mounting base 1, that is, controls the lifting of the lifting column 3. The C-axis 5 passes through the interior of the lifting column 3. Generally, it protrudes downward and is fixedly connected to the saw blade assembly 6. It can protrude upward and be connected to the output end of the C-axis power 4, or it can be connected to the output end of the C-axis power 4 through a reducer near the top of the lifting column 3. The reducer can be installed on the top of the lifting column 3. The lifting column 3 is relatively long, and the C-axis 5 runs through its interior. Therefore, the C-axis 5 in this application is much longer than a traditional C-axis. Vibrations that may be generated when the C-axis power 4 drives the C-axis 5 are quickly buffered in this long C-axis, and may even disappear halfway through transmission, thus not being transmitted to the saw blade assembly 6. On the other hand, the entire C-axis structure is mounted on the lifting column 3, and the overall center of gravity is closer to the lifting mounting base 1. Compared with a traditional C-axis, it is less prone to tilting forward, meaning that the saw blade assembly 6 is more stable during movement. In addition, the increased spacing of the C-axis bearings (i.e., the bearings at both ends of the C-axis) increases the effective force arm, improves the bending rigidity of the C-axis, and reduces the deflection of the cutter head mounted on the C-axis. In other words, when a cutting impact occurs, the cutter head deforms less, thus enhancing the rigidity and impact resistance of the cutter head.

[0022] It should be particularly noted that the technical solution of this application is especially effective with large saw blades, such as those with a diameter of 1600mm, and its stability is better than that of traditional designs. In addition, the lifting mounting base 1, the lifting power 2, and the lifting column 3 will be covered with protective covers in actual production, and the saw blade assembly 6 will also be equipped with a protective cover. This is a common practice for those skilled in the art and will not be elaborated here.

[0023] Preferred, A slide rail 31 is provided on the outside of the lifting column 3, and a slider that cooperates with the slide rail 31 is provided on the lifting mounting base 1.

[0024] Preferred, The lifting column 3 is equipped with a drive rack 32; The output end of the lifting power 2 is equipped with a gear that cooperates with the drive rack 32.

[0025] In this invention, the lifting power 2 drives the lifting column 3 to rise and fall through gears and drive rack 32. It should be noted that this is only one embodiment, and it can also be a screw and nut, which is not limited here.

[0026] Preferred, C-axis 5 is positioned at the exact center of the lifting column 3.

[0027] It should be noted that, as a preferred option, the C-axis 5 is set in the exact center of the lifting column 3. Here, the exact center refers to the center of gravity of the lifting column 3. In this way, the weight of the C-axis power 4, C-axis 5 and saw blade assembly 6 can be brought as close as possible to the lifting column 3, reducing the forward tilting effect caused by traditional designs.

[0028] Preferred, One end of C-axis 5 is connected to the output end of C-axis power 4 via C-axis reducer 7, and a bearing is fitted on the other end. The C-axis reducer 7 and the bearings are respectively installed at both ends of the lifting column 3.

[0029] Preferred, C-axis 5 is hollow inside and has cable entry / exit holes at the top; The connecting cable 8 of the saw blade assembly 6 enters from the bottom of the C-axis 5 and extends from the cable inlet / outlet hole.

[0030] Preferred, The lifting column 3 is a hollow cuboid structure.

[0031] Preferred, The saw blade assembly 6 includes a cutter head holder 61, a saw blade electric spindle 62, an electric spindle rotation motor 63, and a saw blade 64; The tool holder 61 is mounted on the C-axis 5; The saw blade electric spindle 62 is mounted on the cutter head holder 61 and is driven to rotate by the electric spindle rotation motor 63; The saw blade 64 is installed at the output end of the saw blade electric spindle 62; The rotation center line of the saw blade electric spindle 62 is perpendicular to the rotation center line of the C-axis 5.

[0032] The large saw blade C-axis structure of the present invention is used in a cutting machine. The cutting machine includes a movable crossbeam, comprising a lifting mounting base 1, a lifting power source 2, a lifting column 3, a C-axis power source 4, a C-axis 5, and a saw blade assembly 6 mounted on the movable crossbeam. The lifting mounting base 1 has a movable lifting column 3. The lifting power source 2 controls the longitudinal position of the lifting column 3 on the lifting mounting base 1. The lifting column 3 is hollow inside, with the C-axis power source 4 and the saw blade assembly 6 respectively located at its two ends. The C-axis power source 4 drives the rotation of the C-axis 5. The C-axis 5 penetrates the interior of the lifting column 3, with one end connected to the output end of the C-axis power source 4 and the other end fixedly connected to the saw blade assembly 6. By setting a C-axis 5 penetrating from top to bottom inside the hollow lifting column 3, the large saw blade C-axis structure of the present invention, on the one hand, places the C-axis 5 in the middle of the hollow lifting column 3, which reduces the forward tilt of the center of gravity; on the other hand, the long C-axis design can buffer vibration and make transmission more stable, thus solving the problems existing in the prior art.

[0033] The above describes an embodiment of the large saw blade C-axis structure of the present invention. The following describes an embodiment of the cutting machine of the present invention. Please refer to [link / reference]. Figures 3 to 5 The cutting machine of the present invention includes a frame 001 and a movable crossbeam 002, and includes the above-mentioned large saw blade C-axis structure 003; The lifting mounting base in the large saw blade C-axis structure 003 is movably mounted on the moving crossbeam 002.

[0034] Compared to traditional designs, this invention eliminates the need for a conventional C-axis mounting base, resulting in a simpler and more compact structure, and reduced costs, as the traditional C-axis mounting base has higher manufacturing costs. The design of this invention also improves the stability of the cutting machine when using large saw blades. Specifically, the cutting machine described in this application can be a five-axis cutting machine, but this is not limited to that.

[0035] Preferred, It also includes the lifting beam moving component 004; The lifting beam moving component 004 includes a moving seat and a moving power source. The lifting mounting seat is fixedly installed on the moving seat, and the moving power source is used to control the position of the moving seat on the moving crossbeam 002.

[0036] It should be noted that a moving power source can be installed on the moving base. The moving power source drives the lateral movement of the moving base through the drive connector. The drive connector can generally be installed inside the moving crossbeam 002, and can specifically be a screw and nut, which is not limited here.

[0037] The cutting machine of the present invention includes a frame 001 and a movable crossbeam 002, and includes the aforementioned large saw blade C-axis structure 003; the lifting mounting seat in the large saw blade C-axis structure 003 is movably mounted on the movable crossbeam 002. By setting a C-axis 5 running from top to bottom inside the hollow lifting column 3, the cutting machine of the present invention, on the one hand, places the C-axis 5 in the middle of the hollow lifting column 3, which can reduce the forward tilt of the center of gravity; on the other hand, the design of the long C-axis can buffer vibration and make the transmission more stable, thus solving the problems existing in the prior art.

[0038] The above provides a detailed description of the large saw blade C-axis structure and cutting machine provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
