For example, below can include directly below, lower left, lower right, lower front, and lower rear, etc.

[0039] When using a bevel flame cutting torch device to cut a steel plate, in order to be able to realize the automatic adjustment of the main cutting torch and the bevel cutting position, thereby improving the adjustment efficiency and ensuring the quality after cutting, as Figures 1-4 shown, the present invention provides a bevel flame cutting torch device. The bevel flame cutting torch device includes a mounting base 1, a lifting drive assembly 2, a lifting housing 11, a main torch fixing assembly 9, a lateral drive assembly 3, a first transmission assembly 4, a first fixing assembly 5, a second transmission assembly 6, and a second fixing assembly 7.

[0040] Among them, the lifting drive assembly 2 is arranged on the mounting base 1. The lifting housing 11 is in transmission connection with the lifting drive assembly 2, and the lifting drive assembly 2 can drive the lifting housing 11 to lift. The main torch fixing assembly 9 is arranged on the lifting housing 11, and the main cutting torch 100 is arranged on the main torch fixing assembly 9. The transverse drive assembly 3 is arranged on the lifting housing 11. The first transmission assembly 4 is arranged on the lifting housing 11 along the extension direction of the lifting housing 11, and the first transmission assembly 4 is in transmission connection with the transverse drive assembly 3. The first fixing assembly 5 is connected to the first transmission assembly 4, and the transverse drive assembly 3 can drive the first fixing assembly 5 to move towards or away from the main cutting torch 100 through the first transmission assembly 4. The first bevel cutting torch 200 is installed on the first fixing assembly 5. The second transmission assembly 6 is arranged on the lifting housing 11 along the extension direction of the lifting housing 11, and the second transmission assembly 6 is in transmission connection with the transverse drive assembly 3. The second fixing assembly 7 is connected to the second transmission assembly 6, and the transverse drive assembly 3 can drive the second fixing assembly 7 to move towards or away from the main cutting torch 100 through the second transmission assembly 6. The second bevel cutting torch 300 is installed on the second fixing assembly 7.

[0041] When using this bevel flame cutting torch device to cut steel plates, the distance between the main cutting torch 100, the first bevel cutting torch 200 and the second bevel cutting torch 300 and the steel plate can be adjusted by controlling the lifting drive assembly 2, and then the distance between the first fixing assembly 5 and the second fixing assembly 7 and the main cutting torch 100 can be adjusted by controlling the transverse drive assembly 3. Through the above method, the automatic adjustment of the positions of the main cutting torch 100 and the bevel cutting torches is realized, thereby improving the adjustment efficiency. Moreover, by precisely controlling the positions of the main cutting torch 100, the first bevel cutting torch 200 and the second bevel cutting torch 300, the cutting quality can be guaranteed.

[0042] In some embodiments, the lifting drive assembly 2 includes a lifting motor 21, a lifting lead screw 22, and a lifting nut. The lifting motor 21 is fixedly arranged on the mounting base 1, and the output shaft of the lifting motor 21 is in transmission connection with the lifting lead screw 22. The lifting nut is screwed onto the lifting lead screw 22 and is fixedly connected to the lifting housing 11. When controlling the lifting of the main cutting torch 100, the first bevel cutting torch 200, and the second bevel cutting torch 300, it is only necessary to control the rotation direction of the output shaft of the lifting motor 21. The rotation of the output shaft of the lifting motor 21 drives the synchronous rotation of the lifting lead screw 22, and the lifting nut can perform a lifting movement along the axial direction of the lifting lead screw 22, thereby driving the lifting housing 11 to move and adjusting the distance between the lifting housing 11 and the steel plate according to actual needs. In other embodiments, a gear-rack structure can also be adopted. The gear is fixedly sleeved on the output shaft of the lifting motor 21, and the rack is slidably arranged on the mounting base 1. The rotation of the lifting motor 21 drives the gear to rotate, thereby driving the rack engaged with the gear to perform a lifting movement. The rack can drive the lifting housing 11 to move, and the movement of the lifting housing 11 can also be achieved. There are no excessive restrictions here.

[0043] In some embodiments, the main cutting torch fixing assembly 9 includes a first expansion sleeve 91 and a second expansion sleeve 92. The first expansion sleeve 91 is sleeved on the second expansion sleeve 92. The first expansion sleeve 91 is arranged on the mounting base 1, and the first expansion sleeve 91 and the second expansion sleeve 92 are connected by a locking screw 93. The main cutting torch 100 is inserted into the second expansion sleeve 92. Specifically, the first expansion sleeve 91 and the second expansion sleeve 92 adopt a wedge surface fit. Using the wedge expansion principle, the main cutting torch 100 can be stably clamped. After the main cutting torch 100 is stably clamped, the first expansion sleeve 91 and the second expansion sleeve 92 can be completely locked by using the locking screw 93. Through the above settings, it can be ensured that the main cutting torch 100 will not move along its own axial direction, thereby ensuring the smooth progress of the cutting process.

[0044] In some embodiments, the bevel flame cutting torch device further includes a height fine-tuning assembly 8. The height fine-tuning assembly 8 is arranged on the mounting base 1 and is in transmission connection with the main cutting torch 100. The height fine-tuning assembly 8 can adjust the height of the main cutting torch 100. By setting the height fine-tuning assembly 8, the height position of the main cutting torch 100 can be finely adjusted, thereby ensuring the accuracy of cutting processing.

[0045] In some embodiments, the height fine-tuning component 8 includes a fine-tuning motor 81 and a fine-tuning transmission component. The fine-tuning motor 81 is disposed on the mounting base 1, and the fine-tuning motor 81 is in transmission connection with the fine-tuning transmission component. The fine-tuning transmission component is disposed on the mounting base 1, and the fine-tuning transmission component is in transmission connection with the main cutting torch 100. After the position of the main cutting torch 100 is roughly adjusted by the lifting drive component 2, by controlling the operation of the fine-tuning motor 81, the fine-tuning motor 81 drives the main cutting torch 100 to move in the height direction through the fine-tuning transmission component, so as to realize the fine-tuning of the height of the main cutting torch 100 and ensure the cutting effect in the subsequent process.

[0046] In some embodiments, the fine-tuning transmission component includes a driving gear 82, a driven gear 83 and a transmission sleeve 84. The driving gear 82 is fixedly sleeved on the output shaft of the fine-tuning motor 81. The driven gear 83 meshes with the driving gear 82. The transmission sleeve 84 is rotatably sleeved on the first expansion sleeve 91 of the main cutting torch fixing component 9. The outer circumference of the transmission sleeve 84 has an external gear ring, and the external gear ring meshes with the driven gear 83. The transmission sleeve 84 has an internal thread, and the main cutting torch 100 has an external thread. The transmission sleeve 84 is screwed with the external thread of the main cutting torch 100 through the internal thread. When fine-tuning the height of the main cutting torch 100, the fine-tuning motor 81 drives the driving gear 82 to rotate. The driving gear 82 cooperates with the external gear ring through the driven gear 83 to drive the transmission sleeve 84 to rotate. During the rotation of the transmission sleeve 84, the main cutting torch 100 is driven to move up and down through the thread cooperation. By adopting the gear transmission method, the effect of reducing and increasing torque can be achieved, so that the height of the main cutting torch 100 can be effectively adjusted by using a fine-tuning motor 81 with a relatively small volume. When the position of the main cutting torch 100 is adjusted, the first expansion sleeve 91 and the second expansion sleeve 92 are locked by using the locking screw 93. In other embodiments, the gear-rack transmission method can also be adopted to drive the main cutting torch 100 to move up and down, which is not limited here too much. To ensure the smooth rotation of the transmission sleeve 84, a bearing 85 is provided between the transmission sleeve 84 and the mounting base 1.

[0047] In some embodiments, the lateral drive component 3 includes a lateral drive motor 31 and a driving bevel gear 32. The lateral drive motor 31 is fixedly disposed on the lifting housing 11. The driving bevel gear 32 is fixedly sleeved on the output shaft of the lateral drive motor 31. The driving bevel gear 32 is in transmission connection with the first transmission component 4 and the second transmission component 6. During the process of moving the first bevel cutting torch 200 or the second bevel cutting torch 300, the lateral drive motor 31 is started, and the lateral drive motor 31 drives the driving bevel gear 32 to rotate, so as to realize power output. The driving bevel gear 32 drives the first bevel cutting torch 200 or the second bevel cutting torch 300 to move through the first transmission component 4 and the second transmission component 6.

[0048] In some embodiments, the first transmission assembly 4 includes a first bevel gear 41, a first clutch 42, a first lead screw 43, and a first nut 44. The first bevel gear 41 is fixedly arranged coaxially with one end of the first clutch 42, and the first bevel gear 41 meshes with the driving bevel gear 32. The other end of the first clutch 42 is fixedly connected to the first lead screw 43 coaxially. The first nut 44 is screwed onto the first lead screw 43, and the first nut 44 is connected to the first fixing assembly 5. Optionally, the first clutch 42 is an electromagnetic clutch. When adjusting the position of the first bevel cutting torch 200, the lateral driving motor 31 drives the driving bevel gear 32 to rotate, and the driving bevel gear 32 drives the first clutch 42 to rotate through the first bevel gear 41. When the first clutch 42 is in the engaged state, the first clutch drives the first lead screw 43 to rotate, and the first lead screw 43 drives the first nut 44, so that the first fixing assembly 5 moves along the axial direction of the first lead screw 43. By adopting the above method, the position of the first bevel cutting torch 200 can be effectively adjusted automatically, and whether to adjust the position of the first bevel cutting torch 200 can be controlled by controlling the engagement or disconnection of the first clutch 42. In other embodiments, the first lead screw 43 can also be directly driven by a motor, and the first lead screw 43 drives the first nut 44 to move, so as to adjust the position of the first fixing assembly 5. Directly driving the first lead screw 43 by a motor can cancel the lateral driving assembly 3, achieving the effect of simplifying the structure.

[0049] In some embodiments, the first fixing assembly 5 includes a first moving member 51 and a first mounting member 52. The first moving member 51 is fixedly connected to the first nut 44. The first mounting member 52 is arranged on the first moving member 51, and the angle of the first mounting member 52 relative to the first moving member 51 can be adjusted. The first bevel cutting torch 200 is fixedly arranged on the first mounting member 52. During the axial movement of the first nut 44 along the first lead screw 43, the first moving member 51 moves synchronously, thereby adjusting the position of the first bevel cutting torch 200. By rotating the first mounting member 52, the angle of the first bevel cutting torch 200 can be adjusted. Since the common bevel cutting angles for bevel cutting are usually 30°, 45°, or 60°. Therefore, after the angle of the first mounting member 52 relative to the first moving member 51 is adjusted in place, only a positioning pin needs to be inserted through the first mounting member 52 and the first moving member 51 to lock the first mounting member 52. To facilitate the first mounting member 52 to be adjusted to a suitable angle, an angle scale is provided on the first moving member 51, and a pointer is provided on the first mounting member 52. By the above method, the angle of the first bevel cutting torch 200 can be quickly adjusted.

[0050] In some embodiments, a first hoop 53 is fixedly arranged on the first mounting member 52, and the first bevel cutting gun 200 is arranged in the first hoop 53. By arranging the first hoop 53, it is convenient to fix the first bevel cutting gun 200. After the first bevel cutting gun 200 is installed on the first hoop 53, the first bevel cutting gun 200 can be locked on the first mounting member 52 by tightening the locking bolts on the first hoop 53.

[0051] In some embodiments, the second transmission assembly 6 and the first transmission assembly 4 are located on both sides of the main cutting gun 100, and the structure of the second transmission assembly 6 is the same as that of the first transmission assembly 4. The second transmission assembly 6 includes a second bevel gear 61, a second clutch 62, a second lead screw 63 and a second nut 64. The second bevel gear 61 is fixedly arranged coaxially with one end of the second clutch 62, and the second bevel gear 61 meshes with the driving bevel gear 32. The other end of the second clutch 62 is fixedly connected to the second lead screw 63 coaxially. The second nut 64 is screwed on the second lead screw 63, and the second nut 64 is connected to the second fixing assembly 7. Optionally, the second clutch 62 is an electromagnetic clutch. When adjusting the position of the second bevel cutting gun 300, the lateral driving motor 31 drives the driving bevel gear 32 to rotate, and the driving bevel gear 32 drives the second clutch 62 to rotate through the second bevel gear 61. When the second clutch 62 is in the engaged state, the second clutch drives the second lead screw 63 to rotate, and the second lead screw 63 drives the second nut 64, so that the second fixing assembly 7 moves along the axial direction of the second lead screw 63. By adopting the above method, the position of the second bevel cutting gun 300 can be effectively adjusted automatically, and whether to adjust the position of the second bevel cutting gun 300 can be controlled by controlling the engagement or disengagement of the second clutch 62. In other embodiments, the second lead screw 63 can also be directly driven by a motor, and the second lead screw 63 drives the second nut 64 to move to adjust the position of the second fixing assembly 7. Directly driving the second lead screw 63 by a motor can cancel the lateral driving assembly 3, achieving the effect of simplifying the structure.

[0052] In some embodiments, the second fixing component 7 includes a second moving member 71 and a second mounting member 72. The second moving member 71 is fixedly connected to the second nut 64. The second mounting member 72 is disposed on the second moving member 71, and the angle of the second mounting member 72 relative to the second moving member 71 can be adjusted. The second bevel cutting torch 300 is fixedly disposed on the second mounting member 72. During the axial movement of the second nut 64 along the second lead screw 63, the second moving member 71 moves synchronously, thereby adjusting the position of the second bevel cutting torch 300. By rotating the second mounting member 72, the angle of the second bevel cutting torch 300 can be adjusted. Since the common bevel cutting angles in bevel cutting processing are usually 30°, 45°, or 60°. Therefore, after the angle of the second mounting member 72 relative to the second moving member 71 is adjusted in place, it is only necessary to insert a positioning pin through the second mounting member 72 and the second moving member 71 to lock the second mounting member 72. To facilitate the adjustment of the second mounting member 72 to a suitable angle, an angle scale is provided on the second moving member 71, and a pointer is provided on the second mounting member 72. In the above manner, the angle of the second bevel cutting torch 300 can be quickly adjusted.

[0053] In some embodiments, a second clamp 73 is fixedly disposed on the second mounting member 72, and the second bevel cutting torch 300 is disposed in the second clamp 73. By providing the second clamp 73, it is convenient to fix the second bevel cutting torch 300. After the second bevel cutting torch 300 is installed on the second clamp 73, the second bevel cutting torch 300 can be locked on the second mounting member 72 by tightening the locking bolt on the second clamp 73.

[0054] In some embodiments, a height adjustment ring is installed on the mounting base 1, and the installation height position of the height adjustment ring relative to the mounting base 1 can be adjusted. After determining the height to be adjusted, the height adjustment ring is adjusted to the set height position, and then the position of the main cutting torch 100 is adjusted by the lifting drive assembly 2 and the height fine adjustment assembly 8 to be the same as the bottom position of the height adjustment ring. By providing the height adjustment ring as a reference, it is convenient to quickly adjust the position of the main cutting torch 100.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
