It achieves precise assembly and stable support of workpieces through mechanical structures. The rapid clamping structure of blue light welding fixtures is an advanced application of this technology. Its core lies in using blue light scanning for positioning, which can correct workpiece posture deviations in real time, ensure weld seam accuracy, and achieve efficient clamping of materials.

[0003] However, some existing clamping structures require an additional drive source to achieve the clamping and releasing functions of the workpiece. Furthermore, they require additional electrical resources for operation, which not only increases the equipment's energy consumption ratio but also incurs maintenance costs over the long term due to issues such as aging wiring and airtightness failure.

[0004] Therefore, a quick clamping structure for blue light welding fixtures is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick clamping structure for blue light welding fixtures, aiming to improve the problem that some existing clamping structures require additional assembly of a drive source to achieve the clamping and release functions of the workpiece, resulting in high energy consumption and maintenance costs in the later stages of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The quick-clamping structure of the blue light welding fixture includes a base plate, a welding component fixedly connected to the top of the base plate, a pressure plate slidably connected to the inner wall of the base plate, a limit component fixedly connected to the bottom end of the pressure plate, crossbars fixedly connected to both sides of the inner wall of the limit component, ball bearings movably connected to both ends of the crossbars, multiple sliding plates slidably connected to the inner wall of the base plate, grooves for limiting the sliding trajectory of the ball bearings being opened inside the sliding plates, a locking block fixedly connected to the top of the sliding plate, a clamping plate detachably connected to the outside of the locking block, a spring installed inside the base plate, a rotating column fixedly connected to the top of two of the clamping plates, a locking strip rotatably connected to the outside of the rotating column, and a locking frame fixedly connected to the top of the other two clamping plates, the locking frame having a locking groove for engaging with the locking strip inside;

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a quick clamping structure for a blue light welding fixture, including a base plate 1, which serves as the basic support structure for the entire device. A welding assembly is fixedly connected to the top of the base plate 1. The welding assembly includes a robotic arm 2, the bottom of which is fixedly connected to the top of the base plate 1. The base plate 1 provides stable support for the robotic arm 2. A welder 3 is fixedly connected to one end of the robotic arm 2, and a blue light detector 4 is fixedly connected to one side of the welder 3. The robotic arm 2 can drive the welder 3 to perform welding operations on the workpiece, while the blue light detector 4 can ensure the accuracy of the workpiece position during welding and make real-time adjustments based on the current workpiece position. A pressure plate 5 is slidably connected to the inner wall of the base plate 1, providing a stable sliding space for the pressure plate 5.

[0033] A limiting component is fixedly connected to the bottom end of the pressure plate 5. The limiting component includes a limiting plate 6, the top end of which is fixedly connected to the bottom end of the pressure plate 5. The outer side of the limiting plate 6 is slidably connected to the inner wall of the base plate 1. The limiting plate 6 here ensures that the pressure plate 5 will not easily detach from the internal space of the base plate 1. A pressure rod 7 is fixedly connected to the bottom end of the limiting plate 6. The outer side of the pressure rod 7 is slidably connected to the inner wall of the base plate 1. Crossbars 8 are fixedly connected to both sides of the inner wall of the limiting component. When the pressure plate 5 descends, it can drive the pressure rod 7. The crossbar 8 descends together with the horizontal bar 8. The external part of the horizontal bar 8 is fixedly connected to the inner wall of the pressure bar 7. Both ends of the horizontal bar 8 are movably connected to the ball bearings 9. When the horizontal bar 8 descends, it can drive the ball bearings 9 to descend together. Multiple slide plates 10 are slidably connected to the inner wall of the base plate 1. The slide plate 10 has a groove 11 inside to limit the sliding trajectory of the ball bearings 9. When the ball bearings 9 descend, they can slide inside the groove 11. At the same time, because the path of the groove is inclined, the ball bearings 9 will drive the entire slide plate 10 to move inward.

[0034] A locking block 12 is fixedly connected to the top of the skateboard 10. The outer side of the locking block 12 is slidably connected to the inner wall of the base plate 1. When the skateboard 10 moves inward, it can move the locking block 12 together. A clamping plate 13 is detachably connected to the outer side of the locking block 12. The bottom end of the clamping plate 13 is slidably connected to the top of the base plate 1. The clamping plate 13 will move with the locking block 12. A spring 14 is provided inside the base plate 1. One end of the spring 14 is fixedly connected to one side of the limiting plate 6, and the other end of the spring 14 is fixedly connected to the bottom end of the inner wall of the base plate 1. Figure 3 The spring 14 shown is in its normal state. When it is squeezed, it will contract and then quickly return to its original position after the external force is removed.

[0035] Reference Figures 2 to 4Two clamping plates 13 are fixedly connected to the top of a rotating post 15. A retaining strip 16 is rotatably connected to the outside of the rotating post 15. This retaining strip 16 can rotate around the rotating post 15 at the top of the clamping plate 13. The retaining strip 16 is made of rubber and can be bent upwards to a certain extent, while promptly returning to its original position after the external force is removed. The bottom end of the retaining strip 16 is rotatably connected to the top of the clamping plate 13. The tops of the other two clamping plates 13 are fixedly connected to a retaining frame 17. The retaining frame 17 has a retaining groove 18 inside that engages with the retaining strip 16. After the retaining strip 16 engages with the retaining groove 18, it... The clamping plates 13 at both ends can be fixed together to prevent the workpiece from jumping out. The internal threads of the multiple clamping blocks 12 are connected to two threaded rods 19. The external threads of the threaded rods 19 are connected to the inner wall of the clamping plate 13. A knob 20 is fixedly connected to one end of the threaded rod 19. When it is necessary to change the clamping plate 13 according to the shape of the workpiece, the knob 20 can be pulled first, and then the threaded rod 19 can be rotated to disengage it from the inner wall of the clamping plate 13 and the clamping block 12. Then the clamping plate 13 can be removed, and a suitable clamping plate 13 can be replaced. Then the threaded rod 19 can be used to fix the clamping plate 13 and the clamping block 12 together again.

[0036] Working Principle: During operation, the workpiece is placed above the base plate 1. The pressure plate 5 is pressed down by external force, and its bottom limiting plate 6 slides along the inner wall of the base plate 1, compressing the spring 14 and driving the pressure rod 7 and crossbar 8 to descend synchronously. The ball bearings 9 at both ends of the crossbar 8 roll along the sliding groove 11 inside the slide plate 10. Due to the inclined design of the sliding groove 11, the movement trajectory of the ball bearings 9 is converted into the horizontal movement of the slide plate 10 inward. The locking block 12 at the top of the slide plate 10 moves inward accordingly, pushing the clamping plate 13 towards the center, and finally lifting the locking strip 16 a short distance. Then, the locking strip 16 is rotated so that its toothed end aligns with the locking frame 17. Then, the hand is released, and the locking strip 16 falls rapidly under the feedback of its own elastic force, completing the engagement with the locking groove 18, thereby achieving rapid clamping of the workpiece. The sliding connection at the bottom of the clamping plate 13 ensures its smooth movement, while the spring 14 quickly resets after the pressure plate 5 is released, driving the clamping plate 13 to separate, facilitating the loading and unloading of the workpiece.

[0037] During the welding process, the robotic arm 2 drives the welding machine 3 to precisely operate the workpiece, and the blue light detector 4 monitors the position of the workpiece in real time and provides feedback data to adjust the posture of the robotic arm 2 to ensure welding accuracy.

[0038] To change the shape of clamping plate 13 to accommodate different workpieces, the threaded rod 19 can be pulled by knob 20 to release the locking block 12 from the clamping plate 13. After replacement, tighten the threaded rod 19 to complete the adaptation. The entire device, through the combination of mechanical transmission and elastic reset, balances clamping efficiency, positioning accuracy, and operational flexibility, and is suitable for blue light welding scenarios of workpieces of various specifications.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
