Description

Technical Field

[0001] This utility model belongs to the field of laser welding related technology, specifically relating to a convenient laser welding workpiece positioning mechanism. Background Technology

[0002] In laser welding, precise workpiece positioning is crucial for ensuring welding quality and efficiency. However, traditional laser welding workpiece positioning devices have many defects and shortcomings.

[0003] Traditional positioning devices are typically rigid in height adjustment, making it difficult to make flexible adjustments according to different laser welding machines and welding scenarios, thus limiting their application in various working conditions.

[0004] Traditional clamping devices are often only suitable for workpieces of specific shapes and sizes. For workpieces with complex shapes or diverse sizes, the clamping effect is poor, which can easily lead to problems such as displacement and loosening of the workpiece during the welding process, affecting the quality and accuracy of the weld.

[0005] Moreover, when faced with irregularly shaped workpieces, traditional positioning devices often lack effective clamping means and cannot provide stable and reliable positioning, which in turn increases the welding difficulty and scrap rate.

[0006] In addition, the operation of traditional equipment is cumbersome and complicated, which not only increases the difficulty and intensity of work for workers, but also reduces production efficiency. Utility Model Content

[0021] Compared with the prior art, this utility model provides a convenient laser welding workpiece positioning mechanism, which has the following beneficial effects:

[0022] 1. By using a combination of clamping plates, clamping blocks, moving blocks, and sliding grooves, workpieces of various sizes and shapes can be better fixed. Rotating the rocker arm clockwise drives the turntable and the threaded rod to rotate, and the relative movement of the two moving blocks within the sliding groove brings the two clamping plates into contact with and clamps the workpiece. This design effectively clamps the workpiece, ensuring its stability and accuracy. When using this structure for laser welding, the laser welding head can directly weld the workpiece between the clamping plates. Because the workpiece is clamped and its position is stable, the weld seam is more accurate and smaller, which helps improve the quality of laser welding. This structure can flexibly adapt to various workpieces, provides good clamping effect, and reduces weld seam size, thereby improving the quality and efficiency of laser welding.

[0023] 2. By using side clamps, sliders, and side threaded rods, irregular workpieces can be clamped and positioned, ensuring that they are fixed during laser welding and preventing movement. This maintains the stability of the welding position, helps ensure the accuracy and consistency of the welding, improves the quality of laser welding, and avoids welding defects. It also improves the efficiency and quality of laser welding and prevents poor welding results caused by movement.

[0024] 3. The slide rail design makes the movement of the slider smoother and more stable, reduces friction and resistance, and improves the smoothness and accuracy of operation. This helps to ensure the stability of the clamping process and avoids sudden movement or shaking of the workpiece. Attached Figure Description

[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] This utility model provides, for example Figure 1-5 The convenient laser welding workpiece positioning mechanism shown includes a lifting base plate 1 and rotating shaft blocks 4 arranged on both sides above the lifting base plate 1.

[0033] Inner support 3 is provided on the rotating shaft block 4. Outer support 2 is provided on the outside of the two inner support 3. Fixing block 5 is provided between the two outer support 2.

[0034] A welding plate 8 is installed above the lifting top plate 6. A sliding groove 9 is installed on the welding plate 8. A threaded rod 24 is installed at the bottom of the welding plate 8. A turntable 10 is installed at one end of the threaded rod 24. A rocker arm 11 is installed on the outside of the turntable 10. A pair of clamping blocks 12 are installed on the welding plate 8. A positive clamping plate 25 is installed on the clamping block 12. A moving block 14 is installed at the bottom of the clamping block 12. A side clamping threaded rod 20 is installed between the clamping blocks 12. A side clamping knob 13 is installed at one end of the side clamping threaded rod 20.

A slide rail 21 is installed on the metal base plate 15. A side clamping plate 17 is installed on both sides of the clamping block 12. A rotating block 22 is installed behind the outer end of the side clamping plate 17.

[0035] In this embodiment, when using the workpiece positioning device, the workpiece to be welded is simply placed on the welding plate 8. Typically, the workpiece is positioned around the workpiece by using the threaded holes and screws on the welding plate 8 to ensure the welding effect. Then, the two workpieces are welded by the high temperature of the laser welding head. By rotating the lifting knob 7, the lead screw 27 can be rotated, and the connecting rod 28 is simultaneously threaded into the lead screw 27, causing the connecting rod 28 to move towards the fixed block 5. At the same time, during the movement of the inner support 3 and the outer support 2, the slide rod 29 can slide on the sliding groove plate 26. As the slide rod 29 moves to the right in the sliding groove 26, the inner support 3 and the outer support 2 can gradually lift the lifting top plate 6 upward, thereby raising the height of the welding plate 8 to meet the needs of the laser welding machine.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, clamping block 12 is welded to moving block 14, moving block 14 is threaded to lower threaded rod 24, and the threads of the two moving blocks 14 are opposite. Positive clamping plate 25 is welded to clamping block 12. Metal base plate 15 is welded to clamping block 12. Metal side plate 16 is integrally connected to metal base plate 15. Rod sleeve 23 is welded to metal side plate 16. Side clamp threaded rod 20 is inserted into clamping block 12. Rod sleeve 23 is sleeved with side clamp threaded rod 20. One end of side clamp threaded rod 20 passes through metal side plate 16 and is fixedly connected to side clamp knob 13. Slider 19 is threaded to side clamp threaded rod 20, and the threads on the two sliders 19 are opposite. Slider 19 is rotatably connected to support rod 18 via a rotating shaft. Rotating block 22 is welded to side clamping plate 17. Side clamping plate 17 is hinged to clamping block 12. Support rod 18 is rotatably connected to rotating block 22 via a rotating shaft.

[0037] like Figure 2As shown, the threaded rod 24 is inserted into the welding plate 8, the threaded rod 24 is welded to the turntable 10, and the turntable 10 is welded to the rocker arm 11.

[0038] like Figure 5 As shown, the inner support 3 and the outer support 2 are rotatably connected at the middle position by a rotating shaft. The inner support 3 is rotatably connected to the rotating shaft block 4, and the rotating shaft block 4 is welded to the lifting base plate 1. The outer support 2 is rotatably connected to the fixing block 5. The lifting top plate 6 and the welding plate 8 are fixedly installed by screws. The fixing block 5 is welded to the lifting top plate 6. The lifting knob 7 is fixedly connected to the lead screw 27. The lifting knob 7 and the lead screw 27 can rotate on the fixing block 5. The connecting rod 29 is welded to the inner support 3. The lead screw 27 is threadedly connected to the connecting rod 29. The sliding rod 29 is welded to the inner support 3 and the outer support 2 respectively. The sliding groove plate 26 is welded to the lifting top plate 6 and the lifting base plate 1 respectively. The sliding rod 29 can slide in the sliding groove on the lifting top plate 6 and the lifting base plate 1.

[0039] Preferably, by configuring the clamping plates 25, clamping blocks 12, moving blocks 14, threaded rods 24, turntables 10, rocker arms 11, and slides 9, when welding a workpiece, the workpiece to be welded is first placed between the two clamping plates 25. Then, the rocker arm 11 is rotated clockwise to drive the turntable 10 to rotate, which in turn drives the threaded rod 24 to rotate. Since the threads of the two moving blocks 14 are opposite, the two moving blocks 14 move relative to each other inside the slides 9. When the two clamping plates 25 contact the workpiece and clamp it, the laser welding head can then be used to weld the workpiece between the clamping plates 25. This structure avoids the problem that traditional screw positioning devices cannot effectively fix workpieces of many sizes and shapes, and can better clamp the workpieces to be welded, reducing the weld seam between them, thereby improving the quality of laser welding.

[0040] Preferably, by configuring the side clamping plate 17, support rod 18, slider 19, side clamping threaded rod 20, rotating block 22, slide rail 21, side clamping knob 13, and rod sleeve 23, when clamping and positioning irregular workpieces, rotating the side clamping knob 13 can drive the side clamping threaded rod 20 to rotate. Since the threads of the two sliders 19 are opposite, the two sliders 19 move in opposite directions when the side clamping threaded rod 20 rotates. During the movement, the slide rail 21 makes the movement of the sliders 19 smoother. Then, the support rod 18 rotates and pushes the outer ends of the two side clamping plates 17 to rotate, and finally clamps the irregular workpiece, completing the fixing and positioning of the irregular workpiece, preventing the irregular workpiece from moving during laser welding and causing poor welding effect.

[0041] 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.
