Description

Technical Field

[0001] The utility model relates to the technical field of driving mechanisms, in particular to a driving mechanism of a mobile cutting platform. Background Art

[0002] Compared with traditional sheet metal cutting methods, laser cutting has the advantages of fast cutting speed, high production efficiency, good cutting quality, high cutting accuracy, narrow cutting gap, good material adaptability and no tool wear. It has gradually replaced traditional sheet metal cutting methods and is widely used in sheet metal cutting.

[0003] Existing laser cutting machines generally include a bed, a rack working platform, a crossbeam and a laser cutting assembly. The rack working platform is used to support the plate to be cut. The rack working platform can be divided into a mobile cutting platform or a fixed cutting platform. The mobile cutting platform is generally driven by a motor chain, and the chain generally does not have a self-locking function. The position of the mobile cutting platform is generally determined by a travel switch or other sensing method. However, in actual work, the travel switch may fail or the mobile cutting platform may be in place but the chain may move slightly. The slight movement of the chain will also drive the mobile cutting platform to move, causing the position of the plate on the mobile cutting platform relative to the laser cutting assembly to change, which may cause inaccurate processing position of the plate.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model provides a driving mechanism for a mobile cutting platform. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0025] See also Figure 1 and Figure 3 In this embodiment, the power motor 11 is located at the rear side of the bed 100, and the mobile support 200 can drive the mobile cutting platform disposed thereon to move along the width direction (front-back direction) of the bed 100. It should be noted here that, in order to facilitate the description of the driving mechanism, the mobile cutting platform on the mobile support 200 is hidden in this embodiment, and only the mobile support 200 located on the left and right sides of the mobile cutting platform is shown; the chain 18 is also only partially shown.

[0026] See also Figure 1-Figure 6 The utility model provides a driving mechanism for a mobile cutting platform, including a power motor 11, a transmission shaft 13, a sprocket seat 14, a driving sprocket 15, a driven sprocket 16, an adjusting shaft 17, a chain 18, and a platform rotating and clamping assembly 2. The output end of the power motor 11 is connected to the transmission shaft 13 in a transmission manner. The transmission shaft 13 extends along the length direction (left-right direction) of the bed 100. The sprocket seat 14, the driving sprocket 15, the driven sprocket 16, the adjusting shaft 17 and the chain 18 are all provided in two. The two sprocket seats 14 are fixedly connected to the left and right sides of the rear side wall of the bed 100. The two driving sprockets 15 are respectively connected to the corresponding The sprocket seat 14 is rotatably connected, and the two ends of the transmission shaft 13 are rotatably connected to the sprocket seat 14 respectively. The two ends of the transmission shaft 13 are respectively fixedly connected to the driving sprocket 15. The two adjusting shafts 17 respectively pass through the center of the corresponding driven sprockets 16. The two driven sprockets 16 are located in front of the corresponding driving sprockets 15, and the chain 18 is wound between the driving sprockets 15 and the driven sprockets 16 arranged in front and behind. The two chains 18 are respectively fixedly connected to the left side wall or the right side wall of the movable support 200; the platform rotation clamping assembly 2 is arranged on the inner side wall of the bed 100, and is used to clamp the movable support 200 after it moves into place.

[0027] In actual application, the power motor 11 rotates forward, driving the transmission shaft 13 to rotate, and the transmission shaft 13 drives the active sprocket 15 located at both ends of the transmission shaft 13 to rotate synchronously. Due to the setting of the chain 18, the rotational force can be transmitted to the chain 18 and the driven sprocket 16. When the chain 18 moves forward, the chain 18 will drive the mobile support 200 and the mobile cutting platform to move forward synchronously. When the mobile support 200 drives the mobile cutting platform to move to the front end, the power motor 11 stops running. At this time, unloading can be carried out, or the plate to be cut can be loaded onto the mobile cutting platform. After loading is completed, the power motor 11 reverses, driving the transmission shaft 13, the active sprocket 15, and the driven sprocket 16 to rotate, so that the chain 18 and the movable support 200 and the movable cutting platform move backward until the movable support 200 drives the movable cutting platform to move to the rear end (that is, moves to the cutting station), and the control mechanism drives the platform to rotate and clamp the clamping component 2 to operate, and the movable support 200 is clamped and fixed (equivalent to clamping and fixing the movable cutting platform), and an external force is used to provide a locking force for the movable support 200, so as to avoid the displacement of the plate placed on the movable cutting platform due to the displacement of the movable support 200 during the laser cutting process of the laser cutting component, thereby ensuring the cutting accuracy of the plate.

[0028] See also Figure 5 In some embodiments, the left and right side walls of the movable support 200 are both provided with a platform fixing plate 201, and the inner side wall of the bed 100 is provided with a travel switch 101, and the travel switches 101 are provided in two, and the two travel switches 101 are arranged front and back, and the two travel switches 101 are respectively used to sense the front side wall or the rear side wall of any of the platform fixing plates 201. In this embodiment, the two travel switches 101 are located on the left side of the movable support 200. When the movable support 200 and the movable cutting platform move to the front end, the front side wall of the platform fixing plate 201 on the left side contacts the travel switch 101 located in the front; when the movable support 200 and the movable cutting platform move to the rear end, the rear side wall of the platform fixing plate 201 on the left side contacts the travel switch 101 located in the rear, that is, the distance between the two travel switches 101 is the moving travel of the movable cutting platform, and the two travel switches 101 are electrically connected to the control mechanism, and the start and stop of the power motor 11 and the platform rotating and clamping assembly 2 can be controlled through signal transmission.

[0029] See also Figure 6In some embodiments, the inner side wall of the bed 100 is provided with a platform cylinder mounting seat 21, and the front side of the platform cylinder mounting seat 21 is fixedly connected with the platform rotation and clamping assembly 2, and the platform rotation and clamping assembly 2 is a platform rotation and clamping cylinder, and the output end of the platform rotation and clamping cylinder extends toward the front, and the output end of the platform rotation and clamping cylinder is used to abut against the front side wall of the platform fixing plate 201. In this embodiment, the platform rotation and clamping cylinder is located on the right side of the movable support 200, that is, the platform rotation and clamping cylinder is used to clamp the platform fixing plate 201 located on the right side. In actual application, after the output end of the platform rotation and clamping cylinder extends forward and rotates 90°, the output end can be located in front of the platform fixing plate 201, and then the output end contracts backward, so that the output end can clamp the platform fixing plate 201. When the movable support 200 drives the platform fixing plate 201 to move forward or backward, the output end of the platform rotation and clamping cylinder rotates to one side of the platform fixing plate 201 to provide avoidance for the movement of the platform fixing plate 201 .

[0030] See also Figure 5 and Figure 6 In some embodiments, a buffer 102 is provided on the inner side wall of the bed 100. The buffer 102 is provided in four numbers. The four buffers 102 are respectively located at the four corners of the bed 100. The two buffers 102 provided in the front and rear are used to abut against the front side wall or the rear side wall of the corresponding platform fixing plate 201. When the movable support 200 and the movable cutting platform move to the front end, the two buffers 102 located in the front abut against the front side wall of the corresponding platform fixing plate 201 respectively; when the movable support 200 and the movable cutting platform move to the rear end, the two buffers 102 located in the rear abut against the rear side wall of the corresponding platform fixing plate 201 respectively. The above arrangement can avoid hard collision with the platform fixing plate 201 (i.e., the movable cutting platform) and play a protective role.

[0031] See also Figure 2 In some embodiments, a motor seat 103 is fixedly connected to the rear side wall of the bed 100, and the power motor 11 is arranged on the motor seat 103. The output end of the power motor 11 is arranged downward and connected to the reducer 12, and the transmission shaft 13 passes through the center of the reducer 12. The power motor 11 is in transmission connection with the reducer 12, so that the transmission shaft 13 can rotate at a set speed.

[0032] See also Figure 2In some embodiments, a bearing mounting seat 19 is fixedly connected to the rear side wall of the bed 100, and a through hole is formed on the bearing mounting seat 19, in which a bearing seat 20 is fixedly connected, and the transmission shaft 13 passes through the center of the bearing seat 20. The transmission shaft 13 of this embodiment is different from the traditional transmission shaft extending along the width direction (front-to-back direction) of the bed 100. It extends in the length direction (left-to-right direction) of the bed 100, so the length of the transmission shaft 13 is longer. Through the arrangement of the bearing mounting seat 19 and the bearing seat 20, the middle part of the longer transmission shaft 13 can be supported. In addition, the driving mechanism of the utility model can make the mobile cutting platform move along the width direction (i.e., front-to-back direction) of the bed 100, which is different from the traditional mobile platform moving along the length direction (i.e., left-to-right direction) of the bed 100, and can reduce the volume of the bed 100, so it is suitable for use in sites and factories with limited space.

[0033] See also Figure 2 and Figure 5 In some embodiments, a vertical first waist-shaped hole 104 is provided on the front side wall of the motor seat 103, and a first mounting hole is provided on the rear side wall of the bed 100. A first screw (not shown in the figure) is provided in the first waist-shaped hole 104 and the first mounting hole. By providing the first waist-shaped hole 104, the position of the power motor 11 can be adjusted by fine-tuning the position of the motor seat 103 in the up-and-down direction, ensuring that the power motor 11 is concentric with the transmission shaft 13.

[0034] See also Figure 1 and Figure 2 In some embodiments, a vertical second waist-shaped hole 191 is provided on the front side wall of the bearing mounting seat 19, and a second mounting hole is provided on the rear side wall of the bed 100. A second screw (not shown in the figure) is provided in the second waist-shaped hole 191 and the second mounting hole. Similarly, the second waist-shaped hole 191 can also be provided to adjust the position of the bearing seat 20 by fine-tuning the position of the bearing mounting seat 19 in the up-and-down direction, so as to ensure that the bearing seat 20 is concentric with the transmission shaft 13.

[0035] In summary, the utility model can avoid the displacement of the plate placed on the mobile cutting platform during the laser cutting process due to the displacement of the mobile support 200 by providing a power motor 11 for providing power for the rotation of the transmission shaft 13, the driving sprocket 15, and the driven sprocket 16, a chain 18 for synchronously moving the mobile support 200, and a platform rotating clamping assembly 2 for providing a locking force for the mobile support 200 after it is moved into place, thereby ensuring the cutting accuracy of the plate. Two travel switches 101 are provided to monitor the moving travel of the mobile support 200 in real time. A platform rotating cylinder is provided to position the mobile support 200 through the platform fixing plate 201. A buffer 102 is provided to alleviate the impact force after the mobile support 200 is moved into place. A bearing mounting seat 19 and a bearing seat 20 are provided to provide support for the middle part of the transmission shaft 13.
