Description

Technical Field

[0001] The invention belongs to the technical field of snow sled production, and in particular relates to a sled flexible cutting device. Background Art

[0002] Due to the extreme weather and terrain conditions in Antarctica, traditional methods of transportation are difficult to implement. Snow sleds can move effectively on snow and ice, ensuring that researchers and expedition teams can obtain the required materials and equipment in a timely manner. The Antarctic region has low temperatures, strong winds and deep snow all year round, and snow sleds can operate stably under these harsh conditions to ensure the smooth progress of transportation missions. Modern snow sleds can be equipped with a variety of accessories and tools. In addition to transporting materials, they can also be used for scientific research, environmental monitoring, rescue work, etc., enhancing their comprehensive application capabilities in Antarctica. Snow sleds can not only solve the problem of material transportation, but also help scientists and expedition teams to conduct long-term field surveys and research smoothly. It enables polar scientific research activities to continue in such a harsh environment, ensuring material supply and personnel safety.

[0003] When the existing sled flexible cutting device cuts the sled workpiece, it is necessary to place the sled workpiece on a fixed frame and then cut it through a three-dimensional five-axis laser cutting machine. After die-casting, the sled workpiece often has different shapes and sizes. When the sled workpiece is placed on the fixed frame, the components on the fixed frame cannot be moved. If the size or shape of the workpiece changes greatly, the operator needs to manually adjust the position or configuration of the sled workpiece, which increases the complexity and labor intensity of the operation. Especially for workpieces with complex shapes or large size changes, it is impossible to achieve optimal positioning and support every time cutting, resulting in reduced cutting accuracy and even cutting failure. In addition, when cutting, the three-dimensional five-axis laser cutting machine requires more complex calculations and controls to optimize the cutting path due to the complex configuration of the workpiece and the fixed frame. If the cutting path is not properly controlled, it may lead to unstable cutting quality and even irregular cutting surfaces. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figure 1-Figure 4 As shown, a sled flexible cutting device of the present embodiment includes a supporting platform 1 and a supporting frame 2. The center of the top of the supporting frame 2 is hollowed out, and first sliding grooves 35 are opened on both sides of the top surface of the supporting frame 2. A slide plate 32 is arranged inside the first sliding groove 35. A slide seat 34 is slidably connected inside the slide plate 32, and the slide plate 32 limits the slide seat 34. The bottom end of the slide seat 34 is located inside the second sliding groove 36. The synchronous belt 31 is fixedly connected to the slide seat 34 through it. A first hydraulic rod 4 is installed at the bottom end of the slide seat 34, and the telescopic end of the first hydraulic rod 4 is fixedly connected to the fixed seat 9.

[0024] A laser 8 is rotatably connected to one side of the fixed seat 9, which can complete the cutting task without human intervention, which greatly improves production efficiency and shortens the production cycle. Especially when processing large-scale production, it can significantly reduce labor costs and improve production capacity. A laser cutting head 7 is installed at the bottom of the laser 8, and a slide plate 32 is slidably connected to the support frame 2. A plurality of second synchronous wheels 33 are rotatably connected to both sides of the top surface of the slide plate 32, and the plurality of second synchronous wheels 33 are symmetrically arranged in pairs. A plurality of first synchronous wheels 30 are rotatably connected to the corners of the top surface of the support frame 2, and a synchronous belt 31 is transmission-connected between the plurality of first synchronous wheels 30 and the second synchronous wheels 33, which can effectively disperse the load, reduce the wear of a single component, and improve the load adaptability of the system. When the cutting load or workpiece is heavy, the synchronous belt 31 can provide stable power transmission, reduce the performance degradation of the equipment caused by load fluctuations, and ensure the long-term stable operation of the equipment, and the synchronous belt 31 is arranged in an H-shaped structure.

[0025] Since the design of transmission through a synchronous belt 31 usually has better shock absorption performance, compared with metal transmission methods such as gears, it can effectively reduce the noise and vibration of the machine during operation. The lower noise and vibration not only improve the comfort of the working environment, but also avoid the cutting accuracy problem caused by vibration. A second slide groove 36 is opened through the middle of the slide plate 32, and two third motors 5 are installed on both sides of the bottom surface of the support frame 2. The output end of the third motor 5 is rotatably connected to the support frame 2, and the through end of the third motor 5 is fixedly connected to the first synchronous wheel 30, and a spatial motion adjustment platform mechanism is arranged between the support platform 1 and the support frame 2.

[0026] like Figure 5-Figure 11 As shown, the spatial motion adjustment platform mechanism includes a plurality of support plates 11, which are arranged in a circularly symmetrical distribution and fixedly connected to the top surface of the support platform 1. The support plates 11 and the support platform 1 are arranged at an incline, and second hydraulic rods 12 are installed on both sides of the top of the support plates 11. The telescopic end of the second hydraulic rod 12 is rotatably connected to the first connecting plate 13.

[0027] The other ends of the two first connecting plates 13 are rotatably connected, and the middle parts of the two first connecting plates 13 are rotatably connected with the second connecting plate 14. The second connecting plate 14 and the two first connecting plates 13 form a rectangular structure. When the first connecting seat 15 supports the components on its top, and because the support rod 16 is inclined, the overall gravity acts on the support rod 16, so that the support rod 16 not only has a vertical supporting force, but also a lateral or horizontal force. These forces work together to ensure the stability of the structure, and the vertical force of the support rod 16 acts on the first connecting seat 15, so that the second connecting plate 14 and the two first connecting plates 13 can always maintain a horizontal state without tipping over, and the other ends of the two second connecting plates 14 are rotatably connected.

[0028] The top of the connection between the two second connecting plates 14 is rotatably connected to the first connecting seat 15, and the top of the first connecting seat 15 is rotatably connected to the support rod 16. Since the multiple connecting plates 18 are arranged in a circular symmetry with the top plate 10, the connection directions of the multiple connecting plates 18 and the top plate 10 are arranged in three different directions, so that the multiple connecting plates 18 restrict the frame 17 in three directions between each other, so that the connecting plates 18 can support the top plate 10 without causing tipping. The other end of the support rod 16 is rotatably connected to the frame 17, and the frame 17 is arranged in a U-shaped structure. One end of the support rod 16 is located inside the frame 17, and the two sides of the frame 17 are rotatably connected to the connecting plates 18, and the connecting ends of the connecting plates 18 and the support rods 16 in the frame 17 are arranged in a cross, and the top of the connecting plates 18 is fixedly connected to the top plate 10.

[0029] A fixed plate 19 is fixedly connected to one side of the top surface of the top plate 10, and a second threaded rod 25 is rotatably connected to one side of the fixed plate 19 through a bearing, and the second threaded rod 25 is threadedly connected to the bearing in the fixed plate 19, and the fixed plate 19 is rotatably connected to the bearing, and the second threaded rod 25 is threadedly connected to the movable plate 24. Both ends of the second threaded rod 25 are rotatably connected to the top plate 10, and a second knob 26 is installed on one side of the top of the top plate 10, and the second knob 26 connecting shaft is rotatably connected to the top plate 10, and the second knob 26 connecting shaft is fixedly connected to the second threaded rod 25 at the through end.

[0030] like Figure 9-11 As shown, a fixed block 20 is fixedly connected to one side of the top surface of the fixed plate 19, and a plurality of sliding rods 29 are fixedly connected to the outer walls of the fixed block 20 and a plurality of moving blocks 21 on one side of the horizontal axis direction of the fixed block 20. The sliding rods 29 are penetrated and slidably connected with a plurality of moving blocks 21 on one side of the longitudinal axis direction of the fixed block 20, and can handle various types of workpieces, whether small parts with complex shapes or large-sized sled workpieces, and can provide effective support and positioning, which not only increases the scope of use of the equipment, but also reduces the demand for equipment specialization, so that it can be efficiently used in different production tasks. A first threaded rod 22 is rotatably connected to one side of the fixed block 20, and the first threaded rod 22 is penetrated and threadedly connected with a plurality of moving blocks 21 on the horizontal axis direction of the fixed block 20.

[0031] A first knob 23 is rotatably connected to the other side of the fixed block 20. The connecting shaft of the first knob 23 is rotatably connected to the fixed block 20, which can significantly improve the cutting accuracy, adapt to complex workpiece shapes, improve the cutting quality, reduce human errors, enhance the adaptability of the system and improve the overall operating efficiency. The through end of the connecting shaft of the first knob 23 is fixedly connected to the first threaded rod 22. A sleeve 27 is welded on the top surface of the fixed block 20 and several movable blocks 21. A limit rod 28 is engaged inside the several sleeves 27, so that the limit rod 28 can be accurately adjusted according to the different shapes of the workpiece to ensure the stability of the workpiece during the cutting process. Through better support and positioning, the workpiece can maintain a precise relative position during cutting, thereby reducing errors caused by inaccurate positioning and improving the accuracy and consistency of cutting.

[0032] When in use, the limiting rod 28 can be inserted into the sleeve 27 at different positions according to the different shape and structure requirements of the steam workpiece, so as to form a shape that adapts to different sled workpieces. A plurality of movable plates 24 are arranged on one side of the fixed plate 19, and the plurality of movable plates 24 are slidably connected to the top plate 10, and the top plate 10 limits the movable plates 24. The fixed block 20 is respectively provided with a plurality of movable blocks 21 in the transverse and longitudinal directions, and the plurality of movable blocks 21 are respectively located on the top surfaces of the fixed plate 19 and the movable plate 24, and the plurality of movable blocks 21 are respectively slidably connected to the fixed plate 19 and the movable plate 24, and the fixed plate 19 and the movable plate 24 respectively limit the plurality of movable blocks 21 in the transverse and longitudinal directions of the fixed block 20.

[0033] The working principle of this embodiment is as follows: by rotating the first knob 23 and the second knob 26 respectively, the first threaded rod 22 and the second threaded rod 25 are rotated, so that several moving blocks 21 on one side of the fixed block 20 move along the linear direction of the fixed plate 19, and the second threaded rod 25 is rotated so that several moving plates 24 move along the linear direction of the second threaded rod 25, and at the same time, several moving blocks 21 on the top of the moving plate 24 move along the linear direction of the slide rod 29, and the limit rod 28 is inserted into the sleeve 27 as needed to adapt to different sled workpiece shape structures, and then the sled workpiece is placed on the top of the limit rod 28 for engagement and limiting.

[0034] When it is necessary to cut the sled workpiece, the third motors 5 on both sides of the bottom of the support frame 2 are operated. When the two third motors 5 are operated at the same time and in opposite directions, the two first synchronous wheels 30 are driven to rotate in opposite or reverse directions. The slide 34 and the slide plate 32 are in a stuck state. Under the transmission of the synchronous belt 31, the slide plate 32 is driven to move back and forth in the first slide groove 35 of the support frame 2. When the two third motors 5 are operated at the same time and rotate in the same direction, the two first synchronous wheels 30 follow and rotate synchronously, thereby driving the slide 34 to slide in the second slide groove 36. When one third motor 5 is operated and the other third motor 5 is not operated, the slide plate 32 moves back and forth in the first slide groove 35 of the support frame 2 while the slide plate 34 slides in the second slide groove 36 of the slide plate 32. By controlling the operation timing and rotation direction of the two third motors 5, the bottom component of the slide seat 34 can move in any direction based on the parallel surface at the top of the support frame 2 to meet the cutting requirements of sled workpieces of different shapes.

[0035] Furthermore, when the slide 34 moves, the first motor 3 operates to drive the bottom assembly of the slide 34, and then rotates with a plane parallel to the top of the support frame 2. At the same time, the first hydraulic rod 4 of the bottom assembly of the slide 34 operates to drive the bottom assembly to move in the vertical direction, and then the fourth motor 6 operates to drive the laser 8 to rotate, so that the laser cutting head 7 rotates in the vertical direction, so that the laser cutting head 7 meets the requirements for cutting the sled workpiece in three-dimensional space.

[0036] When cutting the sled workpiece, several second hydraulic rods 12 on the top surface of the support platform 1 operate simultaneously or intermittently, driving the first connecting plate 13 to rotate with the connection at the telescopic end of the second hydraulic rod 12 as the origin, so that the second connecting plate 14 follows the movement of the first connecting plate 13, and the two second connecting plates 14 rotate with the connection between each other as the origin, so that the support rods 16 on the top of the three first connecting seats 15 are tilted to different degrees, and then the top plate 10 is tilted to different degrees in three-dimensional space. The cutting angle can be dynamically adjusted according to the different shapes and cutting requirements of the workpiece, so that the equipment can adapt to various complex workpiece shapes and realize more flexible and diversified cutting operations.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
