DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0034] like Figure 1-Figure 9 As shown, a digital twin robot intelligent welding station proposed in the present invention includes a base 1 and a welding robot 10. The number of welding robots 10 is two groups and they are symmetrically fixedly connected to the upper part of the base 1. A sliding seat 5 is slidably arranged on the upper part of the base 1. A first driving device 6 is installed on the side of the sliding seat 5 away from the base 1. Second driving devices 7 are installed on both sides of the output end of the first driving device 6. A rotating fixed platform 8 is installed on the output end of the second driving device 7. A pre-tightening component is arranged on the rotating fixed platform 8. The pre-tightening component includes a movable plate 14 and a plurality of telescopic blocks 19 arranged on the movable plate 14. A plurality of circular grooves 31 are opened on the upper part of the rotating fixed platform 8. An expansion fixing component is arranged on the rotating fixed platform 8. The expansion fixing component includes a plurality of limit rods 23 arranged on the rotating fixed platform 8. A baffle 32 is installed on the upper part of the base 1. Square grooves 33 are opened on both sides of the baffle 32.

[0035] A second sliding groove 12 is provided on the side of the rotating fixed platform 8, and a second sliding block 13 is slidably provided inside the second sliding groove 12, and the second sliding block 13 is fixedly connected to the movable plate 14. A fixed plate 15 is installed on the side of the rotating fixed platform 8, and a second threaded rod 16 is rotatably connected to the upper part of the fixed plate 15, and the second threaded rod 16 is threadedly connected to the second sliding block 13. A plurality of fixing rings 17 are installed on the upper part of the movable plate 14, and a telescopic block 19 is slidably provided on the inner side of the fixing ring 17. A first spring 18 is installed on one end of the telescopic block 19 close to the movable plate 14, and an end of the first spring 18 away from the telescopic block 19 is fixedly connected to the inner side of the fixing ring 17. A plurality of circular grooves 31 are evenly distributed horizontally on the rotating fixed platform 8, and a plurality of telescopic blocks 19 are evenly distributed horizontally on the movable plate 14, and the positions of the telescopic blocks 19 correspond to those of the circular grooves 31.

[0036] A plurality of movable grooves 20 are provided on the upper part of the rotating fixed table 8, a third sliding groove 21 is provided inside the movable groove 20, a third sliding block 22 is slidably provided inside the third sliding groove 21, the third sliding block 22 is rotatably connected to the limiting rod 23, the limiting rod 23 is threadedly connected to the fixing bolt 26, a rubber pad 9 is installed on the end of the fixing bolt 26, a second spring 24 is installed inside the third sliding groove 21, the second spring 24 is slidably connected to the third sliding block 22, a round rod 25 is installed on the side of the third sliding block 22, and one end of the round rod 25 away from the third sliding block 22 is fixedly connected to the side wall of the third sliding groove 21;

[0037] A plurality of open grooves 27 are provided on the side of the rotating fixed table 8, and the open grooves 27 are connected to the third sliding groove 21. A movable rod 29 is slidably provided inside the open groove 27, and a third spring 28 is installed on the side of the movable rod 29. One end of the third spring 28 away from the movable rod 29 is fixedly connected to the side wall of the open groove 27. A plurality of limit blocks 30 are installed on the side of the movable rod 29 away from the third spring 28. The plurality of limit blocks 30 are evenly distributed horizontally on the side of the movable rod 29. The size of the opening formed by two adjacent limit blocks 30 is adapted to the size of the third sliding block 22. The cross-section of the movable groove 20 is trapezoidal, and the limit rod 23 rotates in a circle in the movable groove 20.

[0038] In this embodiment, when it is necessary to fix the workpiece on the rotating fixed table 8 for welding, the workpiece can be directly placed on the rotating fixed table 8, and the telescopic block 19 can be squeezed by the gravity of the workpiece itself. At this time, the first spring 18 is compressed and contracts. At this time, the telescopic blocks 19 under the workpiece are parallel to the rotating fixed table 8, and the telescopic blocks 19 not squeezed by the workpiece are above the rotating fixed table 8, making it difficult for the workpiece to move horizontally, thereby pre-locking the workpiece, avoiding the inconvenience of fixing caused by movement or shaking of the workpiece during the fixing process, and if the workpiece needs to be moved horizontally, the second threaded rod 16 can be rotated at this time, and the force generated by rotating the second threaded rod 16 drives the second sliding block 13 to move along the second sliding groove 12, thereby driving the movable plate 14 to move, so that the movable plate 14 drives all the telescopic blocks 19 to move into the circular groove 31, so that the telescopic blocks 19 are parallel to the rotating fixed table 8, and then the workpiece is moved horizontally. After the movement is completed, the telescopic blocks 19 on the movable plate 14 are reset by rotating the second threaded rod 16, thereby continuing to pre-lock the workpiece;

[0039] When it is necessary to fix the workpiece, the fixing range can be expanded according to the size of the workpiece. First, the movable rod 29 is pulled to retract the movable rod 29 into the open groove 27. At this time, the third spring 28 is contracted, so that the limit block 30 no longer limits and locks the third sliding block 22. The round rod 25 in the stretched state is reset, and then the third sliding block 22 can be made to slide along the third sliding groove 21 and the round rod 25 until it slides to the other side of the third sliding block 22, while driving the limit rod 23 to move. Repeat the operation to move multiple limit rods 23 away from the center position of the rotating fixed table 8. After the workpiece is placed on the rotating fixed table 8, 9 can be pulled to release the limit on the third sliding block 22, and then the third sliding block 22 can be pulled until the limit rod 23 fits with the workpiece, and then the movable rod 29 is released, and the third spring 28 in the contracted state is reset. The third sliding block 22 is limited in position and the limiting block 30 is driven to limit the third sliding block 22. At this time, the round rod 25 is stretched, and since the limiting rod 23 is rotatably connected to the third sliding block 22, the limiting rod 23 can be rotated to move the limiting rod 23 to the side of the workpiece for stable fixation, and then the fixing bolt 26 is rotated. The force generated by rotating the fixing bolt 26 makes the rubber pad 9 at the end of the fixing bolt 26 fix the workpiece. When it is necessary to release the fixation, the movable rod 29 and the limiting block 30 can be used to release the limit of the third sliding block 22, and the second spring 24 in the stretched state will quickly reset, and at the same time drive the limiting rod 23 and the fixing bolt 26 to separate from the workpiece, thereby quickly releasing the fixation, so that the rotating fixed table 8 can be suitable for workpieces of various sizes and shapes, thereby improving the flexibility and adaptability of the production line and enabling the same equipment to handle a variety of different processing tasks.

[0040] Embodiment 2

[0041] like Figure 1-Figure 9 As shown, based on the first embodiment, a first sliding groove 2 is opened on the upper part of the base 1, a first sliding block 3 is slidingly arranged inside the first sliding groove 2, a first threaded rod 4 is rotatably connected inside the first sliding groove 2, the first threaded rod 4 is threadedly connected to the first sliding block 3, the upper part of the first sliding block 3 is fixedly connected to the sliding seat 5, a servo motor 11 is installed on the side of the base 1, and the output end of the servo motor 11 extending to the inner side of the first sliding groove 2 is fixedly connected to the first threaded rod 4.

[0042] In this embodiment, when the welding robot 10 performs welding processing on the workpiece on the rotating fixed table 8, the rotating fixed table 8 can be driven by the first driving device 6 and the second driving device 7 to perform displacement work, and the rotating fixed table 8 outside the baffle 32 can be fixed at the same time. After the welding of the workpiece on the rotating fixed table 8 inside the baffle 32 is completed, the servo motor 11 can be started at this time, and the first threaded rod 4 can be driven to rotate by the servo motor 11. The force generated by the rotation of the first threaded rod 4 drives the first sliding block 3 to move along the first sliding groove 2 until the rotating fixed table 8 on the sliding seat 5 is driven to move. The rotating fixed table 8 in the baffle 32 is moved through the square groove 33 to the outside of the baffle 32, and the rotating fixed table 8 outside the baffle 32 is moved into the baffle 32. Then, the workpiece on the rotating fixed table 8 where welding is completed is released and re-fixed. This facilitates the cyclic processing of the two rotating fixed tables 8, reduces the waiting time for workpiece fixation, and realizes a continuous and uninterrupted production process. This parallel operation method greatly reduces the time wasted in the process of fixing and waiting for welding, thereby improving the overall production efficiency. Shielding by the baffle 32 can reduce the exposure time of workers in harsh environments.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
