Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0026] The cargo hold pillars below deck are equipped with movable deck support seats, and the pillars themselves contain reinforced bulkheads with inverted support seams. Due to the significant amount of welding work required for the pillars, all bevel angles are 40°. Traditional methods employ manual welding using CO2 gas shielded welding, involving multiple layers and passes of welding. This process demands highly skilled personnel, is slow, difficult, and labor-intensive, and results in poor weld formation, leading to extensive grinding work, high labor costs, and a long construction period, thus impacting the overall production cycle. Therefore, it is necessary to research pillar welding technology to improve welding efficiency and quality.

[0027] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-5 A detailed description of the automatic welding equipment is provided.

[0028] This application provides an automatic welding device to improve the welding efficiency and quality of ship pillars. The automatic welding device includes: a welding machine body 1; a positioning and guiding assembly disposed on the welding machine body 1, including multiple positioning and guiding components 2, which are arranged in the length direction of the welding machine body 1 and extend in the width direction of the welding machine body 1; and a clamping component 3 disposed on the welding machine body 1 for fixing the welding torch of the welding machine.

[0029] Specifically, the automatic welding equipment includes a welding machine body 1, a positioning and guiding assembly, and a clamping component 3. The welding machine body 1 includes a chassis, a welding machine, and a fixed frame. The fixed frame fixes the welding machine to the chassis, making the fixed frame and chassis an integrated design, which can effectively suppress vibration during welding, improve welding stability, and avoid weld quality degradation caused by equipment shaking. The clamping component 3 is set on the fixed frame and is used to fix the welding torch of the welding machine. It supports fine adjustment of the welding torch angle or position, which is convenient for different welding positions. The positioning and guiding assembly is set on the welding machine body 1 and includes multiple positioning and guiding components 2. The multiple positioning and guiding components 2 are arranged in the length direction of the fixed frame and each positioning and guiding component 2 extends in the width direction of the fixed frame, forming a multi-dimensional guiding structure. This ensures that the welding torch maintains precise path control during welding, reduces deviation or vibration, reduces dependence on operator skills, and shortens workpiece clamping and calibration time, improving the efficiency of continuous welding. High-precision guidance and stability directly reduce welding defects.

[0030] In some alternative embodiments, multiple positioning guide components 2 extend in the forward or reverse direction of the width of the welding machine body 1.

[0031] Specifically, multiple positioning guide components 2 extend forward toward the width of the welding machine body 1, or extend backward toward the width of the welding machine body 1. Further, multiple positioning guide components 2 extend forward toward the width of the mounting frame, and multiple positioning guide components 2 extend backward toward the width of the mounting frame. The forward or backward extending positioning guide components 2 can cover a wider width range, allowing the welding equipment to handle wider workpieces. The guide components extending forward and backward toward the width of the welding machine body 1 form symmetrical support in the width direction, counteracting the lateral forces or torques generated during welding, reducing welding torch vibration or deviation, and improving welding accuracy. The forward and backward extending guide components can be quickly switched at different angles or directions, reducing repositioning time. By extending bidirectionally toward the width of the welding machine body 1, multiple positioning guide components 2 can achieve wider guidance coverage within a limited space.

[0032] In some alternative embodiments, at least a portion of the positioning guide 2 extends in the positive direction of the width of the fixture, and at least a portion of the positioning guide 2 extends in the opposite direction of the width of the fixture.

[0033] Specifically, the welding torch path can be optimized for specific workpiece structures, avoiding interference or redundant adjustments caused by completely symmetrical designs. Forward or reverse guide components can be flexibly added or removed according to actual needs to adapt to different production line layouts. The forward and reverse guide components extending along the width of the welding machine body 1 form symmetrical support in the width direction, counteracting lateral forces or torques generated during welding, reducing welding torch vibration or deviation, and improving welding accuracy. The forward and reverse extending guide components can be quickly switched at different angles or directions, reducing repositioning time. Multiple positioning guide components 2, arranged bidirectionally along the width of the welding machine body 1, can achieve wider guide coverage within a limited space. Adding reverse extending guide components in areas of concentrated welding stress provides additional support.

[0034] In some optional embodiments, each positioning guide component 2 includes a positioning element 21, a support element 22, a fixing element 23, and a guide element 24. The positioning element 21 and the guide element 24 are disposed at both ends of the support element 22 extending in the width direction of the fixing frame. The fixing element 23 is located between the positioning element 21 and the guide element 24, connecting the support element 22 and the fixing frame. The positioning component connects the support element and the fixing frame.

[0035] Specifically, the guide element 24 is a guide wheel. The guide element 24 extends along the height direction of the welding machine body 1. The automatic welding device uses the column side plate as a base surface, and the guide wheel of the positioning guide component 2 automatically slides and welds based on the base surface, thus meeting the requirements for automatic column welding.

[0036] Furthermore, the guide wheel automatically slides along the base surface of the column side plate, directly utilizing the workpiece's own geometric features as a reference, such as planes and edges, eliminating installation errors of traditional guide rails and ensuring a strict match between the welding torch path and the workpiece contour. The guide wheel extending in the height direction compensates for vertical deviations during workpiece assembly, such as slight column tilt, preventing uneven weld penetration caused by changes in the welding torch's height. Positioning element 21 and guiding element 24 are respectively located at both ends of the length extension direction of support element 22, forming a two-point constraint that restricts the welding torch's degree of freedom in the width direction, preventing lateral drift. Fixing element 23 centrally connects support element 22 and the fixing frame, distributing welding vibration loads and enhancing overall rigidity.

[0037] In some optional embodiments, the positioning element 21 includes a positioning buckle 211, a first locking member 212 and a second locking member 213. The first locking member 212 fixes the positioning buckle 211 and the fixing frame, and the second locking member 213 fixes the positioning buckle 211, the support element 22 and the fixing frame.

[0038] Specifically, the first locking member 212 rigidly fixes the positioning buckle 211 to the fixing frame, forming the main positioning reference and ensuring that the initial position is absolutely fixed. Optionally, the first locking member 212 is a high-strength bolt. The second locking member 213 further locks the positioning buckle 211, the support element 22, and the fixing frame together to eliminate slight slippage between components caused by welding vibration. Optionally, the second locking member 213 is a tapered pin or an anti-loosening bolt. The first locking member 212 bears the main static load, and the second locking member 213 dynamically compensates for the vibration load, avoiding plastic deformation caused by stress concentration from single-point locking.

[0039] In some alternative embodiments, the second locking member 213 includes a pad 2131, a fastener 2132, and a fixing member 2133, the fixing member 2133 fixing the pad 2131 to the positioning buckle 211, and the fastener 2132 fixing the positioning buckle 211, the support element 22, and the fixing bracket.

[0040] Specifically, the pad 2131 distributes the locking pressure to prevent local deformation. The fastener 2133 rigidly fixes the pad 2131 to the positioning buckle 211, forming a basic shear-resistant interface. The fastener 2133 can be a pin or a welded block.

[0041] In some alternative embodiments, the guide element 24 is a guide wheel. The support element 22 is a support rod. The fixing element 23 is a tapered pin or an anti-loosening bolt.

[0042] In some optional embodiments, the clamping component 3 includes a position adjustment element 31, a connecting rod 32 and a latch 33. The position adjustment element 31 is disposed on the fixed frame, the connecting rod 32 is connected to the position adjustment element 31 and the latch 33 respectively, and the latch 33 clamps the welding gun.

[0043] Specifically, the connecting rod 32 is detachably connected to the position adjustment element 31, and the position adjustment element 31 is detachably connected to the welding machine body 1.

[0044] In some alternative embodiments, the position adjustment element 31 includes a lead screw nut and a lead screw, and a connecting rod 32 is connected to the lead screw. The connecting rod 32 includes at least linear segments and / or arcuate segments, and the linear segments and arcuate segments are arranged to form a regular or irregular shape.

[0045] Specifically, there are three linear segments and two arc segments. Any two linear segments are connected by an arc segment, and the included angle of the inscribed circles formed by the arc segments ranges from 0 to 90°.

[0046] On the other hand, this application also provides a positioning guide component 2, which is the positioning guide component 2 mentioned in any of the above claims.

[0047] Specifically, the positioning and guiding component 2 includes a positioning element 21, a supporting element 22, a fixing element 23, and a guiding element 24. The positioning element 21 and the guiding element 24 are disposed at both ends of the supporting element 22 extending in the width direction of the fixing frame. The fixing element 23 is located between the positioning element 21 and the guiding element 24, connecting the supporting element 22 and the fixing frame. The positioning component connects the supporting element and the fixing frame. The positioning element 21 includes a positioning buckle 211, a first locking member 212, and a second locking member 213. The first locking member 212 fixes the positioning buckle 211 and the fixing frame, and the second locking member 213 fixes the positioning buckle 211, the supporting element 22, and the fixing frame. The second locking member 213 includes a pad 2131, a fastener 2132, and a fixing member 2133. The fixing member 2133 fixes the pad 2131 to the positioning buckle 211, and the fastener 2132 fixes the positioning buckle 211, the supporting element 22, and the fixing frame.

[0048] Furthermore, the guide element 24 is a guide wheel. The guide element 24 extends towards the height of the welding machine body 1. The automatic welding device uses the column side plate as a base surface, and the guide wheel of the positioning guide component 2 automatically slides and welds based on the base surface, thus meeting the requirements for automatic column welding.
