Description

Technical Field

[0001] This invention relates to the field of plate welding technology, specifically to a butt welding fixture for plate welding. Background Technology

[0002] Plate welding is a connection technology that uses heating, pressurization, or a combination of both to melt or plastically deform the contact surfaces of metal plates, ultimately forming a strong atomic bond. It is one of the most core connection methods in metal structure manufacturing, capable of splicing scattered plates into complex structures, and the mechanical properties of the joints can be close to or even equivalent to the base material. It can also adapt to the connection needs of plates of different materials and thicknesses, and is widely used in the industrial field. In plate welding, tooling is a special auxiliary equipment designed to ensure the stability of the welding process, meet the assembly accuracy standards, and reduce deformation. It does not directly participate in the welding process, but it is a core auxiliary link that determines the welding quality, efficiency, and safety.

[0003] The tooling for plate welding relies on manual hand-held angle grinders for weld joint pretreatment, which has problems such as missed grinding, uneven grinding depth, difficulty in controlling cleanliness, high labor intensity and low efficiency. Tooling equipped with mechanical cleaning modules is mostly designed for a single process, which can only complete the grinding of flat weld joints and cannot cover complex areas such as tops and corners, requiring secondary manual processing.

[0014] This invention provides a butt welding fixture for plate welding. It has the following advantages: (I) This butt welding fixture for plate welding achieves high-precision positioning and clamping through the collaboration of multiple components. The material placement plate of the supporting component provides a stable bearing foundation for the plate. After the clamping push rod of the clamping component is activated, it can drive the clamping arm to rotate around the rotating rod through the round block and pin shaft, so that the pressure plate evenly presses the plate and avoids local stress concentration. The extended push rod of the top block component can push the bottom shell to slide along the bottom plate. In conjunction with the action of the upper push rod and the elastic component driving the backing plate to tighten during the subsequent cleaning of the top weld joint, the displacement of the plate is restricted from multiple dimensions. This collaborative positioning method effectively eliminates clamping errors, reduces deformation problems such as misalignment and warping during plate welding, lays a solid foundation for welding quality, and ensures that the mechanical properties of the plate connection part after welding are closer to the base material.

[0015] (II) The butt joint tooling used for plate welding uses a phased weld joint cleaning mode. When the weld joint cleaning mechanism is working, the displacement drive of the stroke component can drive the external gear to rotate the screw, so that the displacement plate moves in the slide frame. The angle adjustment plate can flexibly adjust the angle of the grinding component, and in conjunction with the transmission component, drive the grinding wheel to rotate, so as to achieve the initial comprehensive grinding of the plate weld joint. Subsequently, the downward push rod of the top grinding component pushes the displacement component, so that the grinding component can accurately process the top weld joint under the stabilizing effect of the guide slide. At the same time, the chip baffle can block the splashing of chips. The unloading groove of the slide frame and the chip discharge groove of the bottom plate work together to quickly discharge chips, which not only improves the cleanliness of the weld joint to ensure the welding strength, but also avoids the inefficiency and incompleteness of manual cleaning.

[0016] (III) The butt welding fixture for plate welding can collect and process the fumes generated during welding in real time through the internal gas delivery channel and surface pores of the welding mechanism's fume box, reducing the fugitive emissions of harmful particles such as PM2.5 and minimizing the impact on the health of operators. The linkage between the chip removal channel of the base plate and the unloading channel of the sliding frame can promptly discharge the metal chips generated during cleaning, preventing chip accumulation from affecting equipment operation. In addition, the height adjustment push rod of the mounting component can adjust the height of the top plate, the displacement component can flexibly adjust the position of the laser welding head, and the angle adjustment plate can adapt to the needs of cleaning weld joints at different angles, enabling the equipment to handle plate welding operations of different thicknesses and specifications without frequent replacement of special fixtures, significantly improving the applicability and production flexibility of the equipment.

It should be noted that weld cleaning includes two stages: preliminary cleaning of lateral welds and secondary cleaning of top welds, with the two stages being carried out in tandem. Phase 1: Preliminary cleaning of lateral weld joints After the weld cleaning mechanism 2 is started, the displacement drive component 224 in the stroke component 22 drives the external gear 223 to rotate the screw 222, causing the displacement plate 225 to move along the inner wall of the slide frame 221; the displacement plate 225 drives the angle adjustment plate 226 to adjust the angle through the connecting pin, so that the grinding component 23 adapts to the shape and position of the weld; the grinding motor in the transmission component 234 drives the connecting shaft and the grinding wheel 233 to rotate at high speed through the V belt, and grinds and cleans the side weld of the plate; the chip baffle 235 blocks the chips from splashing in all directions during the grinding process and guides the chips to fall into the slide frame 221; Phase 2: Second cleaning of the top weld joint After the lateral cleaning is completed, the top grinding component 32 is activated, and the lower push rod 324 pushes the displacement component 312 downward along the guide slide 322, so that the grinding component 323 approaches the top weld joint of the plate; the power motor in the grinding component 323 drives the grinding wheel to rotate, and performs fine grinding on the top weld joint; the guide slide 322 ensures that the grinding component 323 moves smoothly and avoids vibration affecting the cleaning accuracy; the flue gas box 313 is activated simultaneously during the cleaning process, and absorbs the dust generated by grinding through the surface pores to keep the working environment clean.

[0023] The working principle of this butt welding fixture for plate welding is described in detail below: In use, the plate to be welded is first placed on the material placement plate 123 of the support component 12. Then, the clamping push rod 136 of the clamping component 13 is activated, driving the clamping arm 131 to rotate around the rotating rod 133 via the round block 134 and the pin shaft 135, so that the pressure plate 132 presses the plate to achieve fixation. Next, the extended push rod 211 of the top block component 21 pushes the bottom shell 212 to slide along the bottom plate 111. At this time, the upper push rod 213 is not working. Only the position of the bottom shell 212 is adjusted to maintain the docking accuracy of the auxiliary plate. Then, the weld cleaning mechanism 2 starts to work. The displacement drive component 224 of the stroke component 22 drives the external gear 223 to rotate, which in turn drives the screw 222 to rotate, so that the displacement plate 225 moves in the slide frame 221. The angle adjustment plate 226 adjusts the angle of the grinding component 23 accordingly. At the same time, the transmission component 234 drives the connecting shaft and the grinding wheel 233 on the outer surface to rotate, performing preliminary cleaning of the weld joint of the plate. The debris falls into the chip discharge groove of the base plate 111 through the unloading groove of the sliding frame 221 and is discharged. After the weld cleaning is completed, the wheel motor 316 of the welding mechanism 3 drives the turntable 311 to rotate through the rotating shaft 315. The displacement component 312 adjusts the laser welding head 314 to a suitable welding position. The laser welding head 314 starts to perform welding operations. During this period, the flue gas box 313 treats the welding fumes through the internal gas delivery groove and surface pores. After the welding is completed, the top weld cleaning stage begins. At this time, the upper push rod 213 of the top block component 21 and the elastic component 215 work together to drive the backing plate 214 to press the plate. The lower push rod 324 of the top grinding component 32 pushes the displacement component 312, so that the grinding component 323, under the stabilizing effect of the guide slide 322, further cleans the top weld of the plate. If it is necessary to adapt to the operation requirements of plates of different thicknesses, the height of the top plate 113 can be adjusted by the height adjustment push rod 112 of the mounting component 11.
