Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, and more specifically to a multi-degree-of-freedom parallel metal cutting device. Background Technology

[0002] Metal cutting is a fundamental process in machinery manufacturing, automotive parts processing, and hardware production. Its processing precision, efficiency, and operating environment directly affect the quality and cost of subsequent production stages. As modern manufacturing moves towards high precision, multi-variety, and intensive production, the market demands higher requirements for the functional integration, posture adaptability, and ease of operation of metal cutting equipment. However, traditional metal cutting equipment has gradually revealed many technical limitations in practical applications, making it difficult to meet current production needs.

[0003] Metal cutting devices on the market are mainly divided into two categories: one is simple cutting equipment with a single function, such as handheld cutting machines and fixed abrasive wheel cutting machines. Such equipment can usually only achieve cutting operations on a single plane or at a fixed angle. The position and posture adjustment of the cutting head depends on manual operation, which is not only labor-intensive but also has low adjustment accuracy and is difficult to adapt to complex working conditions such as oblique cutting and variable diameter hole processing.

[0004] Existing cutting technology uses laser cutting heads or blades to cut parts or sheets. While these devices are used for part processing, the cutting angle is relatively fixed and cannot be adjusted by operators to suit the needs of the parts. Adjusting the angle affects the processing accuracy of the parts. Furthermore, they cannot be used to adjust the position of the cutting head to cut processing holes of different diameters, which affects the processing efficiency and quality of the parts. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-degree-of-freedom parallel metal cutting device to solve the problems mentioned in the background art, which involve cutting parts or plates using a laser cutting head or cutting blade. However, the cutting angle is relatively fixed and cannot be adjusted by the operator according to the required cutting angle of the part. Adjusting the precision angle affects the processing accuracy of the part, and it is not possible to adjust the position of the cutting head to cut processing holes of different diameters, which affects the processing efficiency and processing quality of the part.

[0006] The objective of this invention can be achieved through the following technical solutions: A multi-degree-of-freedom parallel metal cutting device includes a plate, an electric track mounted on the plate, a placement plate mounted on the plate for placing parts, a movable frame mounted on the electric track, a cutting head mounted inside the movable frame, and a rotating disk disposed inside the movable frame. The rotating disk is equipped with an adjustment component and a transverse lead screw mechanism. The adjustment component includes a connecting frame located at the lower end of the rotating disk. An electric telescopic rod is fixed to one side of the connecting frame. A support frame is installed on the connecting frame. An electric telescopic rod is fixed to one side of the support frame. A movable column is rotatably connected inside the support frame. The movable column is fixedly connected to the cutting head. Operating the electric telescopic rods one and two allows for multi-angle adjustment of the cutting head. The transverse lead screw mechanism includes a movable motor fixed on the rotating disk. Operating the movable motor causes the transverse lead screw mechanism to drive the cutting head to move laterally, allowing the cutting head to cut processing holes of different diameters.

[0007] As a further embodiment of the present invention: the adjusting assembly includes an adjusting column rotatably connected to the connecting frame, the adjusting column passing through the connecting frame and fixedly connected to the support frame, an adjusting gear fixed at the end of the adjusting column away from the support frame, an adjusting rack fixed at the telescopic end of the first electric telescopic rod, the adjusting gear meshing with the adjusting rack, a movable rack fixed at the telescopic end of the second electric telescopic rod, a movable gear fixedly connected at one end of the movable column extending out of the support frame, and the movable rack meshing with the movable gear.

[0008] As a further aspect of the present invention: an adjusting motor is fixed on the movable frame, the output end of the adjusting motor extends into the movable frame and is fixedly connected to a screw, a connecting plate is threaded onto the screw, and the screw passes through the connecting plate.

[0009] As a further embodiment of the present invention: a motor is fixed on the connecting plate, the output end of the motor is fixedly connected to the rotating disk, a sliding rod is fixed on the movable frame, the sliding rod slides through the connecting plate, and the rotating disk is fixedly connected to the connecting frame.

[0010] As a further aspect of the present invention: the transverse lead screw mechanism includes an adjusting lead screw fixed to the output end of the moving motor, the adjusting lead screw is fixedly connected to a moving block by a ball nut, the moving block extends out of the rotating disk and is fixedly connected to a rotating column, and the moving block is slidably disposed with the rotating disk.

[0011] As a further aspect of the present invention: a limiting post is fixed inside the rotating disk, and the limiting post slides through the moving block.

[0012] As a further aspect of the present invention: a limiting telescopic rod is fixed on the connecting frame, and the telescopic end of the limiting telescopic rod is fixedly connected to the adjusting rack.

[0013] As a further embodiment of the present invention: a sliding column is fixed on one side of the movable rack, and a sliding plate is fixed on one side of the support frame, wherein the sliding column slides through the sliding plate.

[0014] As a further aspect of the present invention: a cleaning column is provided at the lower end of the mobile frame, and an array of cleaning brushes are fixed on the cleaning column. The cleaning brushes correspond to the placement plate, and the placement plate is hollowed out.

[0015] As a further aspect of the present invention: the cleaning column is rotatably connected to the moving frame, a cleaning gear is fixedly connected to one end of the cleaning column, a cleaning rack is fixed on the plate, and the cleaning gear meshes with the cleaning rack.

[0016] The beneficial effects of this invention are: (1) Operate the electric telescopic rod one, causing the adjusting rack to move, driving the adjusting gear to rotate, causing the adjusting column to rotate on the support plate, causing the support frame to move, which is used to adjust the angle of the cutting head, for metal cutting, and to improve the metal cutting accuracy. At the same time, operate the electric telescopic rod two, causing the moving rack to move, causing the moving gear to rotate, driving the moving column to rotate on the support frame, driving the cutting head to move, which is used to adjust the angle of the cutting head, for multi-angle adjustment of the cutting head, for multi-angle cutting of metal. At the same time, operate the adjusting motor, causing the connecting plate to move on the screw, driving the rotating disk to move, causing the cutting head to move, which is used in conjunction with the electric track for the cutting head to move along the X-axis and Y-axis, for multi-angle cutting of metal, to improve the metal cutting accuracy, and to reduce the impact on the metal cutting accuracy and cutting efficiency. (2) Run motor one to make the rotating disk rotate, which in turn makes the cutting head rotate. When it is necessary to cut holes of different diameters, run the moving motor to make the adjusting screw rotate, which makes the ball nut drive the moving block to move. The moving block moves on the limiting column to restrict the moving block, which makes the rotating column move on the rotating disk, and drives the cutting head to move to a suitable distance on the rotating disk. In conjunction with motor one, it is used for the cutting head to cut holes of different diameters, improve the cutting accuracy of the cutting head, and further improve the adaptability of the cutting device.

[0017] (3) When adjusting the rack movement, the extension and retraction of the telescopic rod is restricted to limit the adjustment rack and to adjust the rack movement stably. When the rack moves, the sliding column slides on the sliding plate to restrict the rack movement and to stabilize the rotation of the gear and the cutting head. Then, the cleaning column moves, driving the cleaning brush to clean the debris on the placement plate. The placement plate is hollowed out for placing metal and collecting debris, reducing the impact of debris on the metal cutting accuracy. At the same time, the cleaning column drives the cleaning gear to rotate and move, causing the cleaning column to rotate and drive the cleaning brush to rotate, improving the cleaning effect of the cleaning brush on the placement plate, reducing the residue of debris, and reducing the impact of debris on the metal cutting accuracy.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Based on Example 1, please refer to Figure 1 - Figure 3 As shown, the present invention is a multi-degree-of-freedom parallel metal cutting device, including a plate 1, an electric track 2 installed on the plate 1, a placement plate 21 installed on the plate 1 for placing parts, a movable frame 3 installed on the electric track 2, a cutting head 4 installed inside the movable frame 3, and a rotating disk 20 installed inside the movable frame 3. The rotating disk 20 is equipped with an adjustment component and a transverse lead screw mechanism. The adjustment component includes a connecting frame 25 located at the lower end of the rotating disk 20. An electric telescopic rod 9 is fixed to one side of the connecting frame 25. A support frame 5 is mounted on the connecting frame 25. An electric telescopic rod 10 is fixed to one side of the support frame 5. A movable column 33 is rotatably connected inside the support frame 5. The movable column 33 is fixedly connected to the cutting head 4. The operation of the electric telescopic rod 9 and the electric telescopic rod 10 is used for multi-angle adjustment of the cutting head 4. The transverse lead screw mechanism includes a movable motor 15 fixed on the rotating disk 20. The operation of the movable motor 15 causes the transverse lead screw mechanism to drive the cutting head 4 to move laterally, which is used for the cutting head 4 to cut processing holes of different diameters. The adjustment assembly includes an adjustment column 6 rotatably connected to the connecting frame 25, the adjustment column 6 passing through the connecting frame 25 and fixedly connected to the support frame 5, an adjustment gear 7 fixed to the end of the adjustment column 6 away from the support frame 5, an adjustment rack 8 fixed to the telescopic end of the electric telescopic rod 1 9, the adjustment gear 7 meshing with the adjustment rack 8, a movable rack 11 fixed to the telescopic end of the electric telescopic rod 2 10, and a movable column 33 extending out of the support frame 5 and fixedly connected to a movable gear 12, the movable rack 11 meshing with the movable gear 12. An adjustment motor 22 is fixed on the movable frame 3, the output end of the adjustment motor 22 extending into the movable frame 3 and fixedly connected to a screw 23, a connecting plate 19 threaded onto the screw 23, and the screw 23 passing through the connecting plate 19.

[0023] Specifically, the staff places the metal to be cut on the placement plate 21, operates the electric track 2 to move the moving frame 3, which in turn moves the cutting head 4 to cut the metal. The adjustment mechanism is used for multi-angle adjustment of the cutting head 4 for precise metal cutting, and for adjusting the lateral position of the cutting head 4 to cut processing holes of different diameters, thereby reducing the impact on metal cutting accuracy and cutting efficiency. Specifically, operating the electric telescopic rod 9 causes the adjusting rack 8 to move, which in turn drives the adjusting gear 7 to rotate, causing the adjusting column 6 to rotate on the support plate, thus moving the support frame 5. This is used to adjust the angle of the cutting head 4 for metal cutting, improving the cutting accuracy. Simultaneously, operating the electric telescopic rod 10 causes the moving rack 11 to move, which in turn drives the moving gear 12 to rotate, causing the moving column 33 to rotate on the support frame 5, thus moving the cutting head 4. This is used to adjust the angle of the cutting head 4, enabling multi-angle adjustment of the cutting head 4 for multi-angle metal cutting. At the same time, operating the adjusting motor 22 causes the screw 23 to rotate, causing the connecting plate 19 to move on the screw 23, which in turn drives the rotating disk 20 to move, thus moving the cutting head 4. This, in conjunction with the electric track 2, allows the cutting head 4 to move along the X and Y axes for multi-angle metal cutting, improving the cutting accuracy and reducing the impact on metal cutting precision and efficiency.

[0024] Example 2 Based on Example 1, please refer to Figure 2- Figure 4 As shown, a motor 13 is fixed on the connecting plate 19, and the output end of the motor 13 is fixedly connected to the rotating disk 20. A sliding rod 24 is fixed on the movable frame 3, and the sliding rod 24 slides through the connecting plate 19. The rotating disk 20 is fixedly connected to the connecting frame 25. The transverse screw mechanism includes an adjusting screw 16 fixed to the output end of the movable motor 15. The adjusting screw 16 is fixedly connected to a moving block 18 through a ball nut. The moving block 18 extends out of the rotating disk 20 and is fixedly connected to a rotating column 14. The moving block 18 and the rotating disk 20 are slidably arranged. A limiting column 17 is fixed inside the rotating disk 20, and the limiting column 17 slides through the moving block 18.

[0025] Specifically, the motor 13 rotates the rotating disk 20, which in turn rotates the cutting head 4. When cutting holes of different diameters, the moving motor 15 rotates the adjusting screw 16, which in turn causes the ball nut to move the moving block 18. The moving block 18 moves on the limiting column 17, which restricts the moving block 18, causing the rotating column 14 to move on the rotating disk 20, which in turn moves the cutting head 4 to a suitable distance on the rotating disk 20. This works in conjunction with the motor 13 to cut holes of different diameters with the cutting head 4, improving the cutting accuracy of the cutting head 4 and further enhancing the adaptability of the cutting device. When the connecting plate 19 moves, it moves on the sliding rod 24, which restricts the connecting plate 19 and ensures stable movement of the cutting head 4.

[0026] Example 3 Based on Example 2, please refer to Figure 2 - Figure 4 As shown, a limiting telescopic rod 28 is fixed on the connecting frame 25, and the telescopic end of the limiting telescopic rod 28 is fixedly connected to the adjusting rack 8. A sliding column 26 is fixed on one side of the moving rack 11, and a sliding plate 27 is fixed on one side of the support frame 5. The sliding column 26 slides through the sliding plate 27. A cleaning column 31 is provided at the lower end of the moving frame 3, and an array of cleaning brushes 32 are fixed on the cleaning column 31. The cleaning brushes 32 correspond to the placement plate 21, which is hollow. The cleaning column 31 is rotatably connected to the moving frame 3, and a cleaning gear 30 is fixedly connected to one end of the cleaning column 31. A cleaning rack 29 is fixed on the plate 1, and the cleaning gear 30 meshes with the cleaning rack 29.

[0027] Specifically, when the adjusting rack 8 moves, the extension and retraction of the telescopic rod 28 is restricted to limit the adjustment rack 8 and stabilize its movement. When the moving rack 11 moves, the sliding column 26 slides on the sliding plate 27 to restrict the moving rack 11 and stabilize the rotation of the moving gear 12 and the cutting head 4. When the moving frame 3 moves, the cleaning column 31 moves, driving the cleaning brush 32 to clean the debris on the placement plate 21. The placement plate 21 is hollowed out for placing metal and collecting debris, reducing the impact of debris on the metal cutting accuracy. At the same time, the cleaning column 31 drives the cleaning gear 30 to rotate and move, causing the cleaning gear 30 to move and rotate on the cleaning rack 29, which in turn causes the cleaning column 31 to rotate, driving the cleaning brush 32 to rotate, improving the cleaning effect of the cleaning brush 32 on the placement plate 21, reducing debris residue, reducing the impact of debris on the metal cutting accuracy, and further improving the metal cutting accuracy.

[0028] The working principle of this invention is as follows: The operator places the metal to be cut on the placement plate 21, operates the electric track 2, causing the moving frame 3 to move, which in turn moves the cutting head 4 to cut the metal; then, operates the electric telescopic rod 9, causing the adjusting rack 8 to move, which in turn rotates the adjusting gear 7, causing the adjusting column 6 to rotate on the support plate, which in turn moves the support frame 5, used to adjust the angle of the cutting head 4 for metal cutting and improve the cutting accuracy. At the same time, operates the electric telescopic rod 10, causing the moving rack 11 to move, which in turn rotates the moving gear 12, which in turn rotates the moving column 33 on the support frame 5, which in turn moves the cutting head 4, used to adjust the angle of the cutting head 4 for multi-angle adjustment of the cutting head 4 for multi-angle cutting of the metal. At the same time, operates the adjusting motor 22, causing the screw 23 to rotate, causing the connecting plate 19 to move on the screw 23, which in turn moves the rotating disk 20, which in turn moves the cutting head 4, in conjunction with the electric track 2 for the cutting head 4 to move along the X and Y axes for multi-angle cutting of the metal. Then, motor 13 is operated, causing the rotating disk 20 to rotate, which in turn causes the cutting head 4 to rotate. When cutting holes of different diameters, the moving motor 15 is operated, causing the adjusting screw 16 to rotate, which in turn causes the ball nut to drive the moving block 18 to move. The moving block 18 moves on the limiting column 17, which restricts the moving block 18, causing the rotating column 14 to move on the rotating disk 20, which in turn drives the cutting head 4 to move to a suitable distance on the rotating disk 20. This works in conjunction with motor 13 to allow the cutting head 4 to cut holes of different diameters, improving the cutting accuracy of the cutting head 4 and further enhancing the adaptability of the cutting device. When the connecting plate 19 moves, the connecting plate 19 moves on the sliding rod 24, which restricts the connecting plate 19. Then, when the adjusting rack 8 moves, the extension and retraction of the telescopic rod 28 is restricted to limit the adjustment rack 8 and stabilize its movement. When the moving rack 11 moves, the sliding column 26 slides on the sliding plate 27 to restrict the moving rack 11 and stabilize the rotation of the moving gear 12 and the cutting head 4. When the moving frame 3 moves, the cleaning column 31 moves, driving the cleaning brush 32 to clean the debris on the placement plate 21. The placement plate 21 is hollowed out for placing metal and collecting debris, reducing the impact of debris on the metal cutting accuracy. At the same time, the cleaning column 31 drives the cleaning gear 30 to rotate and move, causing the cleaning gear 30 to move and rotate on the cleaning rack 29, which in turn causes the cleaning column 31 to rotate, driving the cleaning brush 32 to rotate, improving the cleaning effect of the cleaning brush 32 on the placement plate 21, reducing debris residue, reducing the impact of debris on the metal cutting accuracy, and further improving the metal cutting accuracy.

[0029] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention.
