Technical Field
[0001] This utility model relates to the field of welding technology, and in particular to a dual-station friction stir welding clamping device. Background Technology
[0002] Friction stir welding (FSW) is a solid-state joining technology suitable for welding materials such as aluminum alloys, magnesium alloys, and copper alloys. Compared to traditional fusion welding, FSW offers advantages such as no melting, low deformation, and high strength, and is widely used in aerospace, rail transportation, and new energy vehicles.
[0003] During friction stir welding, the kinetic energy generated by friction stir welding will push the plate outward, causing the plate to tilt and reducing work efficiency. During friction stir welding, heat input, mechanical load and material thermal expansion response interact to form a dynamic coupled deformation field, which causes workpiece displacement and affects the final welding quality.
[0004] Based on the above technical issues, it is necessary to design a dual-station friction stir welding clamping device. Utility Model Content

The support frame 5 is slidably mounted in the top groove of the second workstation frame 4. The second workstation frame 4 is located to the right of the first workstation frame 1.

The lead screw 6 is fixedly connected to the output shaft of the first motor 7. The lead screw 6 has a threaded sliding block 8, which is slidably connected to the support frame 5. The connecting frame 9 is slidably connected to the sliding block 8. The processing head 10 is fixedly connected to the left side of the connecting frame 9.
[0023] like Figure 1 and Figure 2 As shown, it also includes a first clamping plate 11, a bidirectional threaded rod 13, a second motor 12, a guide rod 14, and a soft pad 15. The bottom of the placement platform 3 has mounting slots on both the front and rear sides. The bidirectional threaded rod 13 is rotatably connected in the front mounting slot, and the guide rod 14 is fixedly connected in the rear mounting slot. The second motor 12 is fixedly connected to the left side of the placement platform 3. The output shaft of the second motor 12 is fixedly connected to the bidirectional threaded rod 13. The first clamping plate 11 is slidably connected to both sides of the guide rod 14. The bidirectional threaded rod 13 is threadedly connected to the first clamping plate 11. A soft pad 15 is provided on the side of the two first clamping plates 11 that is close to each other. The soft pad 15 is made of rubber.
[0024] like Figure 1 , Figure 3 and Figure 4As shown, it also includes a second clamping plate 16, a rack 17, a third motor 18, and a gear 19. A sliding groove is provided in the middle of the inner side of the placement platform 3. The second clamping plate 16 is slidably arranged on the front and rear sides of the sliding groove. An installation groove is provided inside the placement platform 3. The third motor 18 is installed in the installation groove. The gear 19 is fixedly connected to the output shaft of the third motor 18. A rack 17 is provided on the lower part of the second clamping plate 16 on the side that is close to each other. The gear 19 meshes with the two racks 17.
[0025] like Figure 1 and Figure 5 As shown, it also includes a water tank 20, a telescopic pipe 21, a connecting pipe 22, and a nozzle 23. The water tank 20 is fixedly connected to the left side of the first workstation frame 1. The top of the water tank 20 has an installation hole, and the telescopic pipe 21 is connected to the installation hole.

[0026] When this device is needed, first place the sheet material to be processed on the placement table 3, then start the second motor 12 to drive the bidirectional threaded rod 13 to start rotating. At this time, the first clamping plate 11 will move closer together along the guide rod 14 to clamp the sheet material. Then, activate the third motor 18 in the mounting groove inside the placement table 3. The third motor 18 drives the shaft to start rotating the gear 19. The gear 19 meshes with the racks 17 on the left and right sides. The racks 17 drive the second clamping plate 16 to start moving. At this time, the second clamping plates 16 on the front and rear sides of the placement table 3 move closer together and clamp the sheet material to prevent it from shifting back and forth. Then, the first clamping plate 16 on the top of the support frame 5 can be activated. A motor 7 drives the lead screw 6 to start rotating, and then the position of the sliding block 8 begins to move. It can be stopped when the position is adjusted to a suitable position. The connecting frame 9 can slide left and right on the sliding block 8. When the processing head 10 is adjusted to a suitable position, processing can begin. If the processing temperature starts to overheat, the water pipe connected to the external connection port of the water tank 20 starts to inject water into it. At this time, the connecting pipe 22 connected to the top of the telescopic pipe 21 starts to inject water into the nozzle 23. The nozzle 23 is aimed at the board to start water cooling. Whenever the temperature starts to overheat, water can be injected and the nozzle 23 can be used to cool the board to prevent the board from overheating and causing it to deform.
