[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] Example 1

[0028] Combination Figures 1-3 As shown, an embodiment of this utility model discloses a strip welding fixture, including a worktable 1, a first limiting frame 2, a second limiting frame 3, a first driving member 4, at least two support frames 5, and at least two clamping components 6. The worktable 1 is plate-shaped, and the first limiting frame 2 is fixedly installed at one end of the worktable 1. The second limiting frame 3 is slidably installed at the other end of the worktable 1. The first driving member 4 is fixedly installed on the worktable 1, and its driving end is fixedly connected to the second limiting frame 3. It is used to drive the second limiting frame 3 to move closer to or away from the first limiting frame 2. When two strips need to be welded, it is only necessary to abut the end of one strip against the first limiting frame 2, then align the welding parts of the two strips to be welded, and start the first driving member 4 to control the movement of the second limiting frame 3 to abut the other strip, thus completing the fixation of the two strips to be welded in the length direction of the worktable 1.

[0029] The strip welding fixture of this embodiment includes two support frames 5, which are fixedly installed on the workbench 1 and located in the middle of the first limiting frame 2 and the second limiting frame 3. The upper end of the support frame 5 forms a bearing plane for horizontally placing the strip. Specifically, the support frame 5 includes a bottom bracket 11 and a top support member 12. The top support member 12 has a first bearing surface and a second bearing surface, both of which are flat. The upper end of the bottom bracket 11 forms a mounting groove, and the top support member 12 is embedded in the mounting groove. The thickness of the top support member 12 is the same as the depth of the mounting groove. Two bearing blocks 13 are formed on the first bearing surface of the top support member 12, and the bearing blocks 13 are inclined away from the end face of the top support member 12. Therefore, when welding flat strip, it is only necessary to arrange the second bearing surface upward; when welding inclined or bent strip, it is only necessary to disassemble the top support member 12, flip the top support member 12, and arrange the two bearing blocks 13 on the first bearing surface upward to complete the bearing of the inclined or bent surface. This strip welding fixture allows for flexible adjustment of the position of the second limiting frame 3, moving it closer to or further away from the first limiting frame 2 to accommodate strips of different lengths. By providing at least two support frames 5 and clamping components 6, the strip can be effectively fixed. The bearing plane of the support frame 5 can be used to place the strip horizontally. Since the clamping plate 8 has two clamping surfaces, when the clamping component 6 needs to clamp a flat strip, one clamping surface can be aligned parallel to the bearing plane. When the clamping component 6 needs to clamp an inclined or bent strip, the other clamping surface can be adjusted to be angled to the bearing plane, thus clamping and fixing the strip to be welded. Whether the strip is flat, inclined, or curved, the angle and position of the clamping surface can be adjusted as needed to ensure stable fixing during welding, meeting the needs of producing products of different shapes and greatly improving welding efficiency and product quality.

[0030] Furthermore, the strip welding fixture of this embodiment includes two clamping components 6, which are fixedly installed on one side of the support frame 5 in a one-to-one correspondence; the clamping component 6 includes a telescopic push rod 7 and a clamping plate 8, the telescopic push rod 7 is fixedly installed vertically; one end of the clamping plate 8 is fixedly connected to the telescopic push rod 7, and the other end of the clamping plate 8 extends to the top of the corresponding support frame 5; the clamping plate 8 has two clamping surfaces, one clamping surface is parallel to the bearing plane, and the other clamping surface is at an angle to the bearing plane. In this embodiment, the clamping plate 8 includes a connecting block 9 and a pressing block 10. One end of the connecting block 9 is fixedly connected to the telescopic push rod 7, and the other end of the connecting block 9 extends upward toward the corresponding support frame 5. The pressing block 10 includes a front end and a rear end. The rear end is detachably connected to the other end of the connecting block 9 by bolts. The rear end has a first connecting surface and a second connecting surface arranged vertically opposite to each other, both of which are planar. The front end has a first working surface and a second working surface arranged vertically opposite to each other. The first working surface is a pressing surface and is flush with the first connecting surface. The second working surface is inclined to become another pressing surface. In this embodiment, the bevel angle of the end face of the bearing block 13 away from the top support member 12 is the same as the inclination angle of the corresponding second working surface.

[0031] In other words, when welding flat strip steel, simply remove the pressure block 10 so that the first working surface is facing downwards. Then, under the action of the telescopic push rod 7, the horizontally arranged strip steel can be clamped with the second bearing surface of the top support 12, thus achieving complete fixation of the strip steel during the welding process. When welding inclined or bent strip steel, simply remove the pressure block 10, flip it over so that the second working surface of the pressure block 10 is facing downwards. Then, under the action of the telescopic push rod 7, the inclined or bent strip steel can be clamped with the first bearing surface of the top support 12, thus achieving complete fixation of the strip steel during the welding process.

[0032] Furthermore, the strip welding fixture of this embodiment also includes two auxiliary components 14, which are respectively fixedly installed on one side of the first limiting frame 2 and the second limiting frame 3. Each auxiliary component 14 includes an auxiliary push rod 15 and an auxiliary pressure plate 16. The auxiliary push rod 15 is vertically fixed. One end of the auxiliary pressure plate 16 is fixedly connected to the auxiliary push rod 15, and the other end of the auxiliary pressure plate 16 extends above the corresponding limiting frame. The structure of the auxiliary pressure plate 16 is the same as that of the clamping plate 8. Thus, the two auxiliary components 14, in conjunction with the first limiting frame 2 and the second limiting frame 3, can fix the two ends of the two strips to be welded, and the welding point is located between the two support frames 5, ensuring the stability of the strip during welding.

[0033] Furthermore, this embodiment also includes a lateral limiting component 17 and a lateral abutment component 18. The lateral limiting component 17 and the pressing component 6 are disposed on the same side of the worktable 1, and the lateral abutment component 18 is disposed on the other side of the worktable 1. The end face of the lateral limiting component 17 facing the lateral abutment component 18 is flat. The lateral abutment component 18 includes a mounting plate 19, a abutment push rod 20, and an abutment block 21. The mounting plate 19 is vertically fixed, the abutment push rod 20 is fixedly mounted on the mounting plate 19, and the telescopic end of the abutment push rod 20 is perpendicular to the lateral limiting component 17. The abutment block 21 is fixedly connected to the abutment push rod 20. By pushing the abutment block 21 with the abutment push rod 20, the lateral flatness of the strip steel can be ensured.

[0034] Furthermore, in this embodiment, a limiting plate 22 is formed at the upper end of the bottom support 11. The end face of the limiting plate 22 is flush with the end face of the lateral limiting member 17 facing the lateral abutment member 18. Multiple limiting grooves 23 are formed on the limiting plate 22. Limiting pads 24 are installed on the end face of the lateral limiting member 17 facing the lateral abutment member 18. The thickness of the limiting pads 24 is the same as the thickness of the limiting grooves 23. By adjusting the number of limiting pads 24 to match the multiple limiting grooves 23, it is possible to accommodate strips of different widths.

[0035] It is worth noting that all the drive components and push rods in this embodiment are electric push rods. In other embodiments, actuation or hydraulic push rods may be used.
