Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding-related equipment technology, and in particular to a roller welding device. Background Technology
[0002] A roller is a cylindrical, rotatable object in machinery. Rollers are commonly driven by a power source to move other materials forward or to generate pressure for processing. When performing extended welding operations, two identical rollers need to be placed simultaneously on the worktable of the welding equipment and clamped and fixed in place.
[0003] Currently, an existing roller welding device, with publication number (CN217799792U), includes a device body. A stop for placing the roller is located at the top of the device body. A cavity is formed inside the device body, and a drive gear is rotatably connected inside the cavity. A swing element is located above the drive gear, and multiple top clamping components are located on the side of the swing element. A moving rod is slidably connected to the bottom inner wall of the cavity, and a rack is located at the top of the moving rod. This invention replaces the connecting rod structure used in the prior art with a screw, moving rod, rack, drive gear, swing element, sliding plate, and side clamping assembly, thereby achieving synchronous clamping of the two rollers to be welded. Compared to the existing connecting rod structure, it is not only simpler in structure and lower in cost, but also provides more stable clamping force, further improving the stability of roller clamping.
[0004] Although the technical solutions in the aforementioned comparative documents achieve unified clamping of the two rollers on the welding equipment worktable, they still have the following drawbacks:
[0005] Although the existing device can use the same force to clamp the two rollers to be welded synchronously, it can only clamp rollers with regular shapes. When clamping rollers with irregular shapes (conical or with notches on the surface, etc.), the fixed stop is difficult to align the rollers. Therefore, the existing device has the drawback of low applicability. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a roller welding device that solves the problem of low applicability of existing devices.
[0007] To achieve the above objectives, this utility model provides the following technical solution:

The support mechanism includes a support platform, a limit plate, a threaded groove, and a limit slider. The drive mechanism includes a servo motor, a lead screw, and a support base. The adjustment mechanism includes a hydraulic rod, a lower baffle, and an upper baffle.

[0055] Working principle:
[0056] Place the two rollers into the limiting plates 301 of the two support platforms 3 respectively. At this time, since the rollers are irregularly shaped (conical rollers with grooves), the ends of the two rollers to be welded are usually misaligned. In this case, the servo motor 2 can drive the lead screw 201 to rotate, causing the support platforms 3 to move the rollers and align the two rollers laterally. Then, insert the ends to be joined between the upper baffles 403 (remove the insertion rod 407 to unfold the lower baffle 402 and the upper baffle 403 through the hinge 404, and close them again after installation). After inserting the connecting rod 407, before adjusting the roller laterally, the hydraulic rod 401 needs to be retracted to its limit position to unfold the lower baffle 402 and the upper baffle 403 (to avoid obstructing the roller). Then, the PLC controller 101 controls the hydraulic rod 401 to output or retract, causing the lower baffle 402 and the upper baffle 403 to drive the end of the roller to rise or fall, so that the ends of the two rollers that need to be joined are vertically aligned (the end of the roller away from the adjustment mechanism 4 will be slightly tilted up or down, and the slight misalignment has little impact on the welding). At this time, the two irregular rollers are aligned and welding can be performed.
[0057] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
