Description

Technical Field

[0001] The invention relates to welding equipment, in particular to horizontal plasma welding equipment with the functions of transporting, stacking and unloading materials, and belongs to the technical field of welding. Background Art

[0002] Horizontal plasma welding equipment is a highly automated welding system. Its core feature is that the workpiece is placed and fixed horizontally during the welding process. It uses a compressed arc to generate a high-energy-density plasma arc as a heat source. The energy is concentrated and the penetrating power is extremely strong. It can achieve single-sided welding and double-sided forming. It is particularly good at single-pass welding of medium and thick plates. It is usually equipped with a sophisticated automated control system, tracking system and shielding gas device. It is particularly suitable for the efficient batch production of regular workpieces such as long straight welds and cylindrical circumferential seams.

[0003] After searching, a Chinese patent with publication number CN 216462655 U discloses a horizontal automatic profiling welding device, which includes a welding mechanism, which includes a mounting bracket, a cylinder, a slide rod, an elastic member, a welding gun module and a cylinder profiling pinch wheel. The cylinder and two slide rods are fixed on the mounting bracket, and the telescopic end of the cylinder is connected to a slider, which is slidably set on two slide rods. An elastic member is sleeved on the slide rod, and one end of the elastic member is connected to the slider.

[0004] Although the above solution can weld the workpiece, it still has obvious defects in actual application.

At the same time, it does not have the function of handling and stacking during welding, which restricts the efficiency and quality of the overall welding. To this end, we provide a horizontal plasma welding equipment with handling, stacking and unloading functions to solve the above problems. Summary of the Invention

Drive motors are installed inside the mounting base 1 and inside the adjusting riser 217. The output ends of the two drive motors are fixedly connected to the adjusting riser 217 and the first adjusting screw 218 respectively, and a rotating shaft is installed between the adjusting riser 217 and the mounting base 1, so that starting the two drive motors can effectively drive the adjusting riser 217 and the first adjusting screw 218 to rotate.

[0028] The outer surface of the first adjusting screw 218 is threadedly connected to a threaded adjusting cylinder 219, and the outer surface of the threaded adjusting cylinder 219 is fixedly connected to a connecting frame 220. The outer surface of the connecting frame 220 is slidably connected to the adjusting riser 217, and one end of the connecting frame 220 is fixedly connected to the bearing shell 201. By driving the first adjusting screw 218 to rotate and combining the synergistic effect of the connecting frame 220, the threaded adjusting cylinder 219 can be synchronously moved vertically in the adjusting riser 217. By driving the adjusting riser 217 and the first adjusting screw 218 to rotate, the bearing shell 201 on one end of the connecting frame 220 can be driven to move in different dimensions.

[0029] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 7 The inner top wall of the bearing shell 201 is slidably connected to the limit slider 221, the bottom surface of the limit slider 221 is rotatably connected to the driven worm gear 203, the top surface of the protective shell 205 is fixedly connected to the limit slider 222, and the end of the limit slider 222 away from the protective shell 205 is slidably connected to the bearing shell 201.

Through the setting of the limit slider 222, the protective shell 205 is effectively supported and limited, so that the protective shell 205 is more stable during movement.

[0030] Please refer again Figure 1 、 Figure 2 、 Figure 11 and Figure 12The first and second connecting plates 303 are connected to each other in a sliding manner so as to prevent the first and second connecting plates from sliding off.

[0032] Please refer again Figure 2 and Figure 10 The inner wall of the carrying shell 201 is rotatably connected to the second adjusting screw 4, and the outer surface of the second adjusting screw 4 is threadedly connected to the threaded slider 5. The outer surface of the threaded slider 5 is slidably connected to the carrying shell 201, and the bottom surface of the threaded slider 5 is fixedly connected to the second electric push rod 6. The telescopic end of the second electric push rod 6 is fixedly connected to the mounting bracket 301.

By starting the rotating motor to drive the second adjusting screw 4 to rotate, it can drive the threaded slider 5 to slide in the carrying shell 201, thereby effectively adjusting the welding position of the welding equipment body 309.

[0033] The first electric push rod 305 and the second electric push rod 6 in this application, as well as the mentioned drive motor, rotating motor and central synchronization controller are all common electrical equipment in the prior art. This application will not go into too much detail about their models and internal structures.

[0034] The component structures shown in the accompanying drawings are intended to provide conceptual reference diagrams. Their presentation forms and interrelationships provide a basic framework for understanding the overall design intent. It should be emphasized that these diagrams are not finalized rigid templates. In the process of converting the design into an actual product or its subsystem, in-depth and detailed adaptive adjustments and optimizations must be made based on project-specific constraints. This mainly includes fully considering the core functional requirements of specific application scenarios, strictly evaluating the physical limitations of actual assembly, and strictly referring to the current material properties, manufacturing process levels and cost control requirements. Therefore, the geometric parameters, key dimensions and material specifications of the components need to be systematically reviewed and revised to ensure that the parameters achieve the optimal balance between theoretical feasibility and engineering practicality.

[0035] Working principle: First, by driving the two bidirectional worms 202 to rotate in the same direction, a same-direction meshing force can be applied to both sides of the two driven worm wheels 203 respectively. At the same time, combined with the synergistic effect of the limit slider 221, the two driven worm wheels 203 can be driven to move closer to each other, effectively changing the distance between the two positioning plates 213, so that the positioning plates 213 can be used for workpieces of different lengths. After adjusting the two positioning plates 213 to approach the two ends of the workpiece, the two bidirectional worms 202 are driven again to rotate relative to each other at the same time, which can apply a relative meshing force to both sides of the two driven worm wheels 203 respectively, thereby driving the driven worm wheels 203 to rotate on the bottom surface of the limit slider 221. The rotation of the driven worm wheels 203 drives the transmission rod 204 to rotate, and the transmission rod 204 rotates The second driven bevel gear 209 is driven to rotate, and the second driven bevel gear 209 rotates and drives the first driven bevel gear 208 to rotate through meshing force. The first driven bevel gear 208 rotates and drives the driven worm 207 to rotate. The driven worm 207 rotates and drives the two driven fan-shaped worm gears 210 to rotate with the first limiting rod 214 as the axis through meshing force. The rotation of the driven fan-shaped worm gear 210 drives the first swing arm 211 to swing. The swing of the first swing arm 211 is combined with the coordinated action of the second limiting rod 215 and the auxiliary arm 216 to effectively drive the positioning plate 213 at one end of the second swing arm 212 to move synchronously, thereby effectively clamping and positioning the workpiece. When the workpiece is clamped and positioned, the driven worm 207 is continuously driven to rotate due to the positioning of the workpiece on both sides. The plate 213 cannot move again due to the obstruction of the workpiece, so that the driven worm 207 cannot drive the driven fan-shaped worm gear 210 to rotate with the first limit rod 214 as the axis. At this time, the first limit rod 214 and the second limit rod 215 will work together to drive the limit frame 206 to rotate with the driven worm 207 as the axis. The rotation of the limit frame 206 drives the positioning plate 213 to rotate synchronously. The rotation of the positioning plate 213 effectively drives the workpiece to rotate and change its welding position. By starting the driving motor inside the mounting base plate 1, the adjustment standpipe 217 can be driven to rotate. By starting the driving motor inside the adjustment standpipe 217, the first adjusting screw 218 is driven to rotate. The rotation of the first adjusting screw 218 is combined with the coordinated action of the threaded adjustment cylinder 219 and the connecting frame 220. The function is to drive the supporting shell 201 to move vertically. By adjusting the movement of the vertical tube 217 and the threaded adjustment cylinder 219, the position of the workpiece below the supporting shell 201 can be effectively changed, so that the device can achieve the functions of automatic handling, stacking and unloading of the workpiece during welding. This design not only effectively avoids the problem of the weld deviating from the predetermined trajectory of the welding equipment body 309 due to the movement of the driven workpiece, thereby ensuring the welding quality, but also significantly improves the welding efficiency according to the automated handling, stacking and unloading process. Secondly, by starting the first electric push rod 305, the first connecting plate 303 can be pushed to move. During the movement of the first connecting plate 303, the supporting spring 306, the second connecting plate 304 and the limit seat 307 are combined to form a linkage.It can drive the contact ball 308 to stick to the surface of the workpiece. At the same time, through the resilience of the support spring 306, the welding equipment body 309 can be dynamically and automatically adjusted, so that it can flexibly adapt to cylindrical workpieces with poor roundness, significantly enhancing the adaptability of the equipment to different working conditions and further making the device more practical.
