Technical Field
[0001] This utility model relates to the field of welding auxiliary equipment technology, and in particular to a welding auxiliary device for circular arc weld beads. Background Technology
[0002] In traditional welding operations, the welder holds a welding torch, pointing it at the weld bead to be welded. The welder typically works in a standing or squatting position. In some welding operations, the weld bead is long and exceeds the welder's arm's reach, requiring the welder to move around while welding. The shaking caused by this movement affects the weld quality. While moving around has little impact on the weld quality when welding long, straight weld beads, it can lead to poor weld formation and other defects in curved weld beads.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] This utility model provides a welding auxiliary device for circular arc welds, including a permanent magnet chuck 2, which is used to adhere to the circular arc portion of the workpiece 1 to be welded. The permanent magnet chuck 2 is provided with an adjusting rod 3, and a rotating sleeve 7 is rotatably fitted onto the adjusting rod 3. The rotating sleeve 7 can slide on the adjusting rod 3 and be fixed in different positions. An adjusting screw 4 is connected to the side wall of the rotating sleeve 7. A threaded section is provided at the end of the adjusting screw 4 away from the rotating sleeve 7. A conversion head 5 is fitted onto the threaded section. The end face of the conversion head 5 is provided with a first connecting hole and a second connecting hole, which are perpendicular to each other. The first connecting hole mates with the threaded section, and the threaded section is screwed inside the conversion head 5, allowing adjustment of the position of the conversion head 5 on the threaded section. A movable rod 6 is inserted through the two connecting holes. A movable seat 9 is provided at the end of the movable rod 6 away from the conversion head 5. The movable seat 9 can move together with the movable rod 6. When the worker performs arc welding, the permanent magnet chuck 2 is fixed on the arc part of the workpiece 1 to be welded. The worker can adjust the position of the rotating sleeve 7 on the adjusting rod according to the height of the workpiece 1 to be welded. Furthermore, by turning the adjusting screw 4, the movable rod 6 is moved closer to the adjusting rod 3. The worker can easily align the welding gun with the part to be welded. When the worker completes the welding on one side of the workpiece 1 to be welded, the movable seat 9 works and drives the worker to the unwelded part. The movement process is realized by the movable seat 9. The movable seat 9 runs smoothly without shaking, ensuring the quality of the arc welding.
[0031] It should be noted that the adjusting rod 3 has an adjusting hole 13 that passes through the side wall of the adjusting rod 3 along its height direction. During the installation of the permanent magnet chuck 2, the rotating sleeve 7 is moved to the corresponding height of the adjusting rod 3 according to the height of the workpiece 1 to be welded. A positioning pin 12 is inserted into the adjusting hole 13 closest to the rotating sleeve 7 below the rotating sleeve 7. The end face of the rotating sleeve 7 abuts against the positioning pin 12, and the position of the rotating sleeve 7 and the adjusting rod 3 is locked, so that the distance between the worker and the workpiece 1 to be welded is determined, ensuring a smooth welding process.
[0032] Please refer to the instruction manual appendix. Figure 1 The adjusting rod 3 is set along the height direction of the permanent magnet chuck 2. A rotating sleeve 7 is fitted on the adjusting rod 3. The inner wall of the rotating sleeve 7 is in contact with the outer wall of the adjusting rod 3. An adjusting screw 4 is passed through the side wall of the rotating sleeve 7. The adjusting screw 4 is perpendicular to the axis of the rotating sleeve 7. Furthermore, the adjusting screw 4 can rotate around the adjusting rod 3 together with the rotating sleeve 7. The adjusting screw 4 can also rotate around its own axis inside the rotating sleeve 7. The threaded section of the adjusting screw 4 is engaged with the first connecting hole of the conversion head 5. The moving rod 6 is engaged with the second connecting hole. The first connecting hole and the second connecting hole are perpendicular. The corresponding moving rod 6 is set perpendicular to the adjusting screw 4. The moving rod 6 is parallel to the adjusting rod 3. The distance between them is changed by turning the adjusting screw 4, and the position of the moving seat 9 and the workpiece 1 to be welded is adjusted. After the worker sits on the moving seat 9, he can aim the welding gun at the weld bead to be welded. Since the weld bead to be welded is specifically arc-shaped, after the worker completes a certain arc of the weld bead, the moving seat 9 is rotated. The moving seat 9 can make a circular motion around the adjusting rod 3 on the outside of the workpiece 1 to be welded, which will drive the worker to the unwelded part. During the welding process, the worker moves by moving the moving seat 9. The moving seat 9 runs smoothly without shaking, ensuring that the formed arc weld bead is free of welding defects.
[0033] Furthermore, a fastening hole is provided on the adapter 5. The fastening hole is perpendicular to the first connecting hole and the second connecting hole, respectively. It should be noted that the first connecting hole and the second connecting hole are set independently. The fastening hole passes through the end face of the second connecting hole and communicates with the inner cavity of the second connecting hole. A first fastener 10 is threaded into the fastening hole. The end face of the first fastener 10 extends into the inner cavity of the second connecting hole. By screwing the first fastener 10 inward, the first fastener 10 abuts against the inner wall of the moving rod 6. The first fastener 10 determines the relative position of the adapter 5 and the moving rod 6. In some embodiments, the rotating sleeve 7 is positioned on the adjusting rod 3. The position of the rotating sleeve 7 is determined by each adjusting hole 13. Since each adjusting hole 13 is spaced the same, the adjustable position is limited and cannot accommodate the various sizes of the workpiece 1 to be welded. After the rotating sleeve 7 is initially positioned by the adjusting holes 13, the moving rod 6 is adjusted so that the moving seat 9 connected to the moving rod 6 is placed stably on the ground. Then, the first fastener 10 is tightened to lock the position of the moving rod 6. By adjusting the positions of the moving rod 6 and the rotating sleeve 7 respectively, the setting state of the moving seat 9 is made more precise and the movement is more stable.
[0034] Please refer to the instruction manual appendix. Figure 3 The movable seat 9 includes a base plate 92 and a seat plate 91 for supporting the worker. Support screws are provided between the base plate 92 and the seat plate 91. In one embodiment of this invention, both the base plate 92 and the seat plate 91 are rectangular. Four support bolts 93 are provided at each vertex of the base plate 92 and the seat plate 91. Two parallel pressure sensors 94 are clamped between the base plate 92 and the seat plate 91. An electric controller 96 is provided between the two pressure sensors 94. The electric controller 96 can receive pressure information collected by the pressure sensors 94 on both sides and compare the magnitude of the pressure information on both sides. Furthermore, the electric controller 96 also contains a motor. After comparing the pressure information, the controller 96 controls the output end of the motor to rotate towards the side with greater pressure. The output end of the motor is connected to a drive wheel 95, which is perpendicular to the base plate 92 and passes through the base plate 92 and contacts the bottom surface. When the pressure sensors 94 on both sides of the movable seat 9 receive different pressures, the controller 96 controls the movable seat 9 to move towards the side with greater pressure. In addition, each pressure sensor 94 is located at the edge of the base plate 92 and the seat plate 91 to avoid the pressure information collected by the two sensors being too close and similar, making it difficult for the controller 96 to compare and determine the side with greater pressure.
[0035] It should be noted that the electronic control computer 96 can also calculate the pressure information difference between the two sides of the movable seat 9 and make the speed of the motor positively correlated with the pressure information difference. In some embodiments, the worker squats on the movable seat 9. After the worker finishes welding a certain arc segment of the circular arc weld, he can tilt his body to the unwelded side to change his center of gravity. The pressure information collected by the pressure sensors 94 on both sides of the movable seat 9 will show a difference, and the side where the worker tilts will receive greater pressure. The electronic control computer 96 controls the drive wheel 95 to rotate, and the movable seat 9 drives the worker to rotate around the workpiece 1 to be welded, so that the unwelded part is within the welding range of the worker's arm. Furthermore, the worker can control the movement speed of the movable seat 9 by changing the degree of body tilt. The worker controls the displacement of the movable seat 9 by tilting his body. This process does not produce any shaking, ensuring the welding quality of the circular arc weld.
[0036] Please refer to the instruction manual appendix. Figure 4 The drive wheel 95 is located on the side of the base plate 92 away from the workpiece 1 to be welded. A caster wheel 97 is provided on the side of the base plate 92 close to the workpiece 1 to be welded. The caster wheel 97 includes a connecting part 9701 and a wheel body 9702. The connecting part 9701 passes through the base plate 92. The size of the wheel body 9702 is larger than the size of the connecting part 9701. The connection between the wheel body 9702 and the connecting part 9701 forms an annular stepped surface. The annular stepped surface abuts against the base plate 92, fixing the caster wheel 97 to the base plate 92. When the drive wheel 95 rotates, the caster wheel 97 assists the drive wheel 95 in moving.
[0037] In addition, a bracket 8 is provided on the movable rod 6. The bracket 8 can be L-shaped, with a through hole on the shorter side. The bracket 8 is inserted through the through hole onto the movable rod 6 and can slide on the movable rod 6. A second fastener 11 is inserted into the through hole on the bracket 8. The worker can adjust the bracket 8 to a suitable position according to his / her needs, and at the same time screw the second fastener 11 into the through hole so that the end face of the second fastener 11 abuts against the movable rod 6. The side wall of the movable rod 6 is in close contact with the inner wall of the through hole. The friction fixes the position of the movable rod 6 and the bracket 8. At the end of the longer part of the bracket 8, there are arm rests extending to both sides of the bracket 8. When welding, the worker puts his / her arm on the arm rest to avoid fatigue caused by the operator's arm being raised for a long time, which could lead to unstable welding quality.
[0038] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0039] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
