Detailed Implementation

[0036] Example 1

[0037] like Figure 1-4 As shown, the present invention proposes a multi-purpose welding fixture with quick-change chucks, including a worktable 1, a chuck body 8, a connecting seat 12, a support assembly, a rotating assembly, and a limiting assembly;

[0038] There are two connecting seats 12, which are symmetrically arranged at the top of both ends of the worktable 1 and connected to the chuck body 8. The side of the connecting seat 12 is provided with an adjustment component that is connected to the worktable 1 and adjusts the position of the connecting seat 12 in use.

[0039] The rotating assembly is located at the bottom of the worktable 1 and in the middle of the worktable 1;

[0040] The limiting component is positioned above the connecting seat 12 and extends to the end of the connecting seat 12 at both ends and wraps around the outer side of the end of the connecting seat 12. The inner side of the limiting component is in contact with the end of the chuck body 8.

[0041] The support assembly is located at the bottom of the worktable 1 and on the side of the rotating assembly, and the number of support assemblies is at least two.

[0042] In an optional embodiment, the side of the connecting seat 12 is provided with a mounting groove 14, and the upper and lower parts of one end of the chuck body 8 are provided with connecting grooves 19. The cross-sectional shape of the mounting groove 14 is T-shaped. When the chuck body 8 and the connecting seat 12 are installed together, one end of the chuck body 8 is fitted into the mounting groove 14, and the opening of the mounting groove 14 is fitted into the connecting groove 19.

[0043] In this embodiment, one end of the chuck body 8 is slidably mounted on one side of the connecting seat 12 through the cooperation of the connecting groove 19 and the mounting groove 14, and the limiting component is placed on the connecting seat 12. The limiting component is wrapped around the outside of the connecting seat 12 by its own weight, and the inner wall of the limiting component is tightly fitted to the end of the connecting seat 12 and the end of the chuck body 8, fixing the chuck body 8 in the mounting groove 14. This achieves quick replacement and stable fixation of the chuck body 8. At the same time, the position and height of the connecting seat 12 are adjusted by the adjusting component, so that the connecting seat 12 drives the chuck body 8 to adjust synchronously. At the same time, the cooperation of the rotating component and the support component provides support for the worktable 1 while the support plate 2 rotates, making the rotation of the worktable 1 more stable. The position of the chuck body 8 is further adjusted so that the chuck body 8 can adapt to different workpiece clamping requirements and is suitable for various welding scenarios.

[0044] Example 2

[0045] like Figure 3 As shown, the present invention proposes a multi-purpose welding fixture with quick-change chucks. The difference between this embodiment and the first embodiment is that the limiting component includes a limiting plate 6 and a handle 7.

[0046] The limiting plate 6 is set at the top of the connecting seat 12 and extends to the ends of the connecting seat 12 at both ends and wraps around the ends of the connecting seat 12.

[0047] The handle 7 is positioned at the top of the limit plate 6.

[0048] In an optional embodiment, the limiting plate 6 has a sliding groove 16 on both sides inside, and the connecting seat 12 has a sliding strip 15 at both ends and at the edge of the mounting groove 14. When the limiting plate 6 and the connecting seat 12 are installed together, the sliding strip 15 is accommodated in the sliding groove 16 to limit the two ends of the limiting plate 6 during use, to prevent the ends of the limiting plate 6 from bending, and to improve the limiting strength of the limiting plate 6 on the clamp body 8.

[0049] In an optional embodiment, magnets 13 are provided on the inner top of the limiting plate 6 and the top of the connecting seat 12, and the two magnets 13 are attracted to each other.

[0050] In this embodiment, the limiting plate 6 is slidably installed on the connecting seat 12 along the height direction of the connecting seat 12 by the cooperation of the slide bar 15 and the slide groove 16, ensuring that the limiting plate 6 is not easily displaced laterally, and that the limiting plate 6 restricts the chuck body 8 in the mounting groove 14. The attraction effect of the magnet 13 enhances the connection stability between the limiting plate 6 and the connecting seat 12. At the same time, the handle 7 drives the limiting plate 6 to be flexibly adjusted in the height direction of the connecting seat 12, making the connection and separation of the limiting plate 6 and the connecting seat 12 more convenient, and making the connection and separation of the chuck body 8 and the connecting seat 12 more convenient, and making the disassembly and replacement of the chuck body 8 more convenient.

[0051] Example 3

[0052] like Figure 2 As shown, this utility model proposes a multi-purpose welding fixture with quick-change chucks. Compared with the first embodiment, the difference in this embodiment is that the adjustment component includes a mounting plate 9, a first telescopic rod 10, and a second telescopic rod 11; wherein the first telescopic rod 10 and the second telescopic rod 11 are all one of hydraulic cylinders, air cylinders, and electric telescopic rods.

[0053] The second telescopic rod 11 is installed at the end of the worktable 1 with the piston rod facing upwards towards the worktable 1;

[0054] Mounting plate 9 is installed on the top of the piston rod of the second telescopic rod 11;

[0055] The first telescopic rod 10 is installed at the top of the mounting plate 9 with the piston rod facing the middle of the worktable 1 and connected to the connecting seat 12.

[0056] In this embodiment, the piston rod of the second telescopic rod 11 extends and retracts, driving the mounting plate 9 to move, thereby pushing the first telescopic rod 10 to adjust the height of the connecting seat 12. At the same time, the extension and retraction of the piston rod of the first telescopic rod 10 can adjust the position of the connecting seat 12 above the worktable 1, ensuring that the fixture can stably clamp the workpiece under different working conditions, thereby improving welding accuracy and efficiency.

[0057] Example 4

[0058] like Figure 1 and Figure 4 As shown, the present invention proposes a multi-purpose welding fixture with quick-change chucks. The difference between this embodiment and the first embodiment is that the rotating assembly includes a support plate 2, a support leg 3 and a rotating shaft 17.

[0059] The support plate 2 is set at the bottom center of the workbench 1, and the size of the support plate 2 is adapted to the width of the workbench 1. A motor can be installed at the bottom center of the support plate 2, which is used to drive the workbench 1 to rotate on the support plate 2 during use, making the rotation adjustment of the workbench 1 more convenient.

[0060] The rotating shaft 17 is installed at the bottom center of the worktable 1 and connected to the bearing of the support plate 2;

[0061] The number of support legs 3 is multiple, and the multiple support legs 3 are arranged at equal angles at the bottom edge of the support plate 2 to support the support plate 2 during use, so that the support plate 2 is placed horizontally and stably.

[0062] In an optional embodiment, the bottom end of the worktable 1 is provided with a plurality of balls 18, which are all located at the top edge of the support plate 2 and are arranged at equal angles according to the center of the support plate 2.

[0063] In this embodiment, a rotating shaft 17 is installed at the bottom of the worktable 1 and connected to the bearing of the support plate 2. This limits the rotation of the worktable 1 on the support plate 2 and makes rotation more convenient. At the same time, by setting multiple balls 18 at the bottom of the worktable 1 and rollingly connecting them to the upper surface of the support plate 2, the worktable 1 is ensured to be stable and flexible during rotation, which improves the overall ease of use of the fixture. It is suitable for various welding scenarios and meets the fixing requirements of different workpieces.

[0064] Example 5

[0065] like Figure 1 As shown, the present invention proposes a multi-purpose welding fixture with quick-change chucks. The difference between this embodiment and the first embodiment is that the support assembly includes a moving wheel 4 and a column 5.

[0066] The column 5 is installed on one side of the bottom end of the workbench 1;

[0067] The caster 4 is installed at the bottom of the column 5. The caster 4 is one of a swivel caster and a directional caster. The caster 4 has a brake to limit the rotation of the worktable 1 during use.

[0068] In this embodiment, the cooperation of the movable wheel 4 and the column 5 provides support between the end of the workbench 1 and the ground, thereby improving the stability of the end of the workbench 1. Furthermore, the movable wheel 4 ensures that the movable wheel 4 and the column 5 always support the workbench 1 when it rotates at any angle, thus improving the stability of the workbench 1.

[0069] In this invention, one end of the chuck body 8 is slidably mounted on one side of the connecting seat 12 through the cooperation of the connecting groove 19 and the mounting groove 14. The limiting plate 6 is placed above the connecting seat 12 using the handle 7, causing the limiting plate 6 to move downwards under its own weight. This allows the slide bar 15 to be installed in the slide groove 16, and the limiting plate 6 to wrap around the outside of the connecting seat 12 and fit snugly against the end of the chuck body 8, fixing the chuck body 8 in the mounting groove 14. This achieves quick replacement and stable fixation of the chuck body 8. Simultaneously, the piston rod of the second telescopic rod 11 extends and retracts, driving... The mounting plate 9 moves, thereby pushing the first telescopic rod 10 to adjust the height of the connecting seat 12. The position of the connecting seat 12 above the worktable 1 can be adjusted by extending and retracting the piston rod of the first telescopic rod 10. At the same time, it is mounted on the bottom end of the worktable 1 via the rotating shaft 17, and the rotating shaft 17 is connected to the bearing of the support plate 2, so that the worktable 1 rotates on the support plate 2. The cooperation between the moving wheel 4 and the column 5 supports the end of the worktable 1, so that the position of the chuck body 8 can be further adjusted, so that the chuck body 8 can adapt to different workpiece clamping requirements and is suitable for various welding scenarios.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
