Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, and in particular to an online correction device for seam welding wheels. Background Technology
[0002] In continuous seam welding operations, the upper and lower welding wheels are subjected to high temperatures and friction for extended periods, leading to surface wear and oxide layer buildup, resulting in uneven welds or even incomplete welds. Traditional correction methods require stopping the machine, disassembling the welding wheels, and repairing them using external grinding equipment, which is cumbersome and inefficient. Existing online dressing devices mostly use fixed cutters and lack dynamic pressure compensation, making them prone to over- or under-dressing due to uneven welding wheel wear or equipment vibration, and their adjustment accuracy is limited.

The wheel correction mechanism is provided on one side of both the upper welding wheel and the lower welding wheel. The wheel correction mechanism includes a tool holder, a high-speed steel knife, an adjusting screw, a slider, a nut, a spring, a mounting bracket, and a slide rail. The tool holder is mounted on the frame, and the slide rail is provided on the inner walls of both sides of the tool holder. The slider is slidably mounted between the two slide rails. One side of the slider is connected to one side of the mounting bracket, and the high-speed steel knife is installed inside the other side of the mounting bracket. The other side of the slider is connected to one end of the adjusting screw, and the other end of the adjusting screw passes through one side of the tool holder and is threadedly connected to the nut. The spring is sleeved on the adjusting screw, and the cutting edges of the two high-speed steel knives face the upper welding wheel and the lower welding wheel respectively.

[0016] The present invention will be further described in conjunction with the accompanying drawings and embodiments.
[0017] like Figure 1 , 2 As shown, the online correction device for seam welding wheels of this utility model includes an upper welding wheel 1 and a lower welding wheel 2 mounted on a frame, and a wheel correction mechanism 3. The wheel correction mechanism 3 is provided on one side of both the upper welding wheel 1 and the lower welding wheel 2. The wheel correction mechanism 3 includes a tool holder 31, a high-speed steel knife 32, an adjusting screw 33, a slider 34, a nut 35, a spring 36, a mounting bracket 37, and a slide rail 38. The tool holder 31 is mounted on the frame, and the slide rail 38 is provided on the inner walls of both sides of the tool holder 31. The surface of the slide rail 38 is chrome-plated with a thickness of 0.05mm. The slider 34, made of aluminum alloy, is slidably mounted between the two slide rails 38. The slider 34 has a gap between it and the slide rail 38. In conjunction with the sliding block 34, the slider 34 is slidably installed between the slide rails 38 to achieve precise lateral displacement. One side of the slider 34 is connected to one side of the mounting bracket 37, and the other side of the mounting bracket 37 is equipped with the high-speed steel knife 32. The other side of the slider 34 is connected to one end of the adjusting screw 33. The other end of the adjusting screw 33 passes through one side of the knife holder 31 and is threadedly connected to the nut 35. The adjusting screw 33 is fitted with the spring 36. The cutting edges of the two high-speed steel knives 32 are respectively facing the upper welding wheel 1 and the lower welding wheel 2. The cutting edges of the high-speed steel knives are at a 0-5° angle to the tangent of the outer circle of the welding wheel to ensure that the dressing force is applied tangentially and to reduce tool vibration caused by radial force.
[0018] The cutting edges of the two stainless steel blades 32 are respectively aligned with the outer tangents of the upper welding wheel 1 and the lower welding wheel 2. The blade holder 31 is mounted on the frame with fixing bolts. The stainless steel blades 32 are fixed to the front end of the mounting bracket 37 with M6 hexagon socket head cap screws. During initial installation, the cutting edges are adjusted to align with the outer tangents of the welding wheels (tilt angle ≤ 3°). The stainless steel blades 32 are mounted on the mounting bracket 37 with fixing bolts.
[0019] The spring 36 is sleeved on the adjusting screw 33 between the other side of the slider 34 and one side wall of the tool holder 31, providing reverse elastic support force to avoid overload during trimming and automatically compensate for changes in welding wheel diameter or surface unevenness. The spring 36 is preferably a stainless steel disc spring.
[0020] Working principle:
[0021] 1. Start the welding wheel to rotate, observe the weld quality, and determine the repair requirements.
[0022] 2. Loosen the nut 35, and push the slider 34 and the steel blade 32 toward the welding wheel by adjusting the screw 33 until the cutting edge contacts the surface of the welding wheel, and then tighten the nut 35 to fix the position.
[0023] 3. During the finishing process, spring 36 absorbs the radial runout of the welding wheel and maintains a constant finishing pressure. When the finishing sparks are uniform and continuous, it indicates that the finishing is complete.
[0024] 4. When replacing the stainless steel blade, simply remove the fixing bolts on the mounting bracket 37 for quick replacement.
[0025] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
