Description

Technical Field

[0001] The invention relates to the technical field related to welding clamping, and in particular to an adjusting welding device for producing ship metal parts. Background Art

[0002] In the shipbuilding industry, which is highly technology-intensive and labor-intensive, the welding of metal parts is not just a simple material connection process, but also one of the key processes for building the entire hull structure. As a large-scale water transportation vehicle, ships have complex structures, strong load-bearing capacity, and harsh operating environment, so the requirements for welding technology are extremely strict, especially the welding of T-shaped interfaces. Due to its complex structure, diverse sizes, and extremely high requirements for welding accuracy, it has become a recognized difficulty and focus in the ship production process. As one of the most common connection methods in the hull structure, T-shaped interfaces are widely used in the connection of key parts such as hull decks, side walls, and bulkheads. This interface not only requires high welding strength and good sealing, but also must be able to withstand various complex stresses and environmental changes that the hull may encounter during navigation.

[0003] The traditional T-joint welding method often relies on manual operation. From positioning, clamping to welding, each step requires workers to make fine manual adjustments. This method is not only inefficient and cannot meet the high requirements of modern shipbuilding industry for production speed and quality, but also the welding quality is difficult to guarantee. In the clamping stage, the traditional clamping method often uses manual or simple mechanical devices, which is difficult to achieve a stable clamping of the T-joint, which not only increases the labor intensity of workers, but also may cause welding defects caused by unstable clamping during welding. In the welding stage, due to the diversity of T-joint sizes and the requirements for welding accuracy, workers need to constantly adjust welding parameters and welding positions to ensure welding quality and neat appearance. However, this manual adjustment is often affected by the worker's skill level and fatigue level, resulting in instability and poor consistency of welding quality. Summary of the invention

[0037] The welding clamping mechanism 38 includes four groups of clamps, namely the first clamp 3801, the second clamp 3802, the third clamp 3803 and the fourth clamp 3804. The clamp includes a first rotating tube 39. A connecting plate clamping piece 40 is fixedly connected to one side of the first rotating tube 39. The connecting plate clamping piece 40 is tangent to the side of the first rotating tube 39 and is used to clamp the connecting plate 56. A vertical plate clamping piece 41 is also rotatably connected to the first rotating tube 39. The vertical plate clamping piece 41 is used for the vertical plate 57. There are more than three groups of vertical plate clamping pieces 41. A second rotating tube 4101 is provided on the vertical plate clamping piece 41. The second rotating tube 4101 is rotatably connected to the first rotating tube 39. A clamping block 4103 is fixedly connected to one side of the vertical plate clamping piece 41 on the second rotating tube 4101 through a buffer spring 4102, which is used to clamp the vertical plate 57.

[0038] A clamping drive shaft 42 passes through the first rotating tube 39, the clamping drive shaft 42 in the first clamp 3801 is fixedly connected to the first gear 13, the clamping drive shaft 42 in the second clamp 3802 is fixedly connected to the second gear 17, the clamping drive shaft 42 in the third clamp 3803 is fixedly connected to the third gear 21, and the clamping drive shaft 42 in the fourth clamp 3804 is fixedly connected to the fourth gear 25.

[0039] A reversing gear set 51 is arranged below the second rotating tube 4101, and the reversing gear set 51 includes a first gear ring 5101, and the first gear ring 5101 is fixedly connected to the clamping drive shaft 42, a second gear ring 5102 is arranged on one side of the first gear ring 5101, and the second gear ring 5102 is rotatably connected to the first rotating tube 39, a first transmission gear 5103 is meshed on the inner side of the first gear ring 5101, and a second transmission gear 5104 is meshed on the inner side of the second gear ring 5102, and the first transmission gear 5103 and the second transmission gear 5104 are meshed on the inner side of the second gear ring 5102. The two transmission gears 5104 are meshed with each other, and the first transmission gear 5103 and the second transmission gear 5104 are both rotatably connected to the first rotating tube 39, so that when the clamping drive shaft 42 rotates counterclockwise, it will drive the first gear ring 5101 to rotate counterclockwise, and then the first gear ring 5101 drives the first transmission gear 5103 to rotate clockwise, and the first transmission gear 5103 drives the second gear ring 5102 to rotate clockwise, thereby realizing the reverse rotation of the second gear ring 5102 and the clamping drive shaft 42.

[0040] In one example, a set of reversing gear sets 51 are additionally provided at the lower ends of the clamping drive shafts 42 in the second clamp 3802 and the fourth clamp 3804, so that the clamping drive shafts 42 in the second clamp 3802 and the fourth clamp 3804 rotate in opposite directions to the clamping drive shafts 42 in the first clamp 3801 and the third clamp 3803, so that the relative clamps can clamp the connecting plate 56 and the vertical plate 57.

[0041] Taking the first clamp 3801 as an example, the clamping drive shaft 42 in the first clamp 3801 is processed with a group of bidirectional threads 43 on one side of each group of connecting plate clamping plates 40, and the bidirectional threads 43 are meshed with a first screw nut 44, and a first rotation limiting strip 4401 is processed on the side of the first screw nut 44. The first screw nut 44 is slidingly connected to the first rotating tube 39 through the first rotation limiting strip 4401. An elastic pressure plate 45 is arranged in the second rotating tube 4101, and a second rotation limiting strip 4501 is processed on the outer side of the elastic pressure plate 45. The elastic pressure plate 45 is slidingly connected to the second rotating tube 4101 through the second rotation limiting strip 4501. A movable block 46 is arranged on one side of the elastic pressure plate 45, and a third rotation limiting strip 4501 is processed on the outer side of the movable block 46. The movable block 46 is slidably connected to the second rotating tube 4101 through the third rotation limiting bar 4601, a first pressure spring 47 is arranged between the elastic pressure plate 45 and the movable block 46, and the two ends of the first pressure spring 47 are respectively fixedly connected to the elastic pressure plate 45 and the movable block 46, a first one-way ratchet 48 is processed below the movable block 46, and a second one-way ratchet 49 is fixedly connected above the second transmission gear 5104, the first one-way ratchet 48 and the second one-way ratchet 49 are meshed with each other, a second pressure spring 50 is arranged between the movable block 46 and the second one-way ratchet 49, and the two ends of the second pressure spring 50 are respectively fixedly connected to the movable block 46 and the second one-way ratchet 49, so that when the clamping drive shaft 42 rotates, it will first drive the first slider 1 2. The second slider 16, the third slider 20 and the fourth slider 24 move toward the center, so that the connecting plate clamping piece 40 clamps the connecting plate 56. After the connecting plate clamping piece 40 is clamped, it cannot move anymore. At the same time, it is restricted by the first rotation limiting strip 4401 and the first screw nut 44 cannot rotate. Therefore, the first screw nut 44 will move up and down along the bidirectional thread 43 because the clamping drive shaft 42 continues to rotate, so that when moving downward, the elastic pressure plate 45 will be pushed downward, and then the movable block 46 will be pushed downward through the first pressure spring 47, so that the first one-way ratchet 48 and the second one-way ratchet 49 are meshed with each other, so that the second gear ring 5102 rotating in the opposite direction will drive the movable block 46 to rotate in the opposite direction together, and because the third rotation limiting strip 4601 The restriction makes the movable block 46 drive the second rotating tube 4101 and the vertical plate clamping piece 41 to rotate in the opposite direction together, so that the vertical plate clamping piece 41 can clamp the vertical plate 57 in place. When the clamping drive shaft 42 continues to rotate, the first screw nut 44 will move upward and temporarily disengage from the elastic pressure plate 45, so that the first one-way ratchet 48 and the second one-way ratchet 49 will disengage from the meshing under the push of the second pressure spring 50, and then the second gear ring 5102 will no longer drive the vertical plate clamping piece 41 to rotate in the opposite direction. At this time, the clamping drive shaft 42 will drive the elastic pressure plate 45 and the movable block 46 to rotate forward due to the friction force, so that the vertical plate clamping piece 41 rotates forward, stops clamping the vertical plate 57, and rotates until it is in close contact with the connecting plate clamping piece 40.Leave enough space for the welding robot arm 4 to perform welding.

[0042] The positions of the first screw nuts 44 corresponding to the plurality of sets of vertical plate clamping pieces 41 on the bidirectional threads 43 are gradually changed at equal intervals, so that when the clamping drive shaft 42 rotates, the plurality of sets of vertical plate clamping pieces 41 rotate in sequence. At the same time, the output shaft of the driving motor 7 is also fixedly connected to a large pulley 52, and a small pulley 53 is rotatably connected above the moving guide rail 2. The small pulley 53 is fixedly connected to a bidirectional screw rod 54, and the bidirectional screw rod 54 passes through the moving slider 3. The moving slider 3 is transmission-connected to the bidirectional screw rod 54 through the second screw nut 55, thereby driving the welding robot arm 4 to reciprocate along the moving guide rail 2. The pulley transmission links the movement of the welding robot arm 4 with the vertical plate clamping piece 41, and the complete reciprocating cycle of the second screw nut 55 is consistent with the complete reciprocating cycle of the first screw nut 44. During debugging, the position of the welding robot arm 4 is adjusted so that the movement of the welding robot arm 4 is associated with the rotation of the vertical plate clamping piece 41, so that when the welding robot arm 4 moves, the vertical plate clamping piece 41 located in front of the welding robot arm 4 will be opened in advance and pressed against the connecting plate clamping piece 40, so that it will not hinder the welding of the welding robot arm 4, making the welding work smoother.

[0043] Working principle: When welding, first place the connecting plate 56 between the connecting plate clamping pieces 40, and place the vertical plate 57 between the vertical plate clamping pieces 41, then start the drive motor 7 to drive the first slider 12, the second slider 16, the third slider 20 and the fourth slider 24 to move toward the center, so that the connecting plate clamping piece 40 clamps the connecting plate 56. After the connecting plate clamping piece 40 moves into place, it cannot move anymore. At the same time, it is restricted by the first rotation limiting strip 4401, and the first screw nut 44 cannot rotate, so that the first screw nut 4 4 will move up and down along the bidirectional thread 43 as the clamping drive shaft 42 continues to rotate, so that when moving downward, the elastic pressure plate 45 will be pushed downward, and then the movable block 46 will be pushed downward through the first pressure spring 47, so that the first one-way ratchet 48 and the second one-way ratchet 49 will be meshed with each other, so that the second gear ring 5102 rotating in the opposite direction will drive the movable block 46 to rotate in the opposite direction together, and due to the restriction of the third rotation limiting strip 4601, the movable block 46 drives the second rotating tube 4101 and the vertical plate clamping piece 41 to rotate in the opposite direction together, In this way, the vertical plate clamping piece 41 can clamp the vertical plate 57 in place. When the clamping drive shaft 42 continues to rotate, the first screw nut 44 will move upward and temporarily disengage from the elastic pressure plate 45, so that the first one-way ratchet 48 and the second one-way ratchet 49 will disengage under the push of the second pressure spring 50, and then the second gear ring 5102 will no longer drive the vertical plate clamping piece 41 to rotate in the opposite direction. At this time, the clamping drive shaft 42 will drive the elastic pressure plate 45 and the movable block 46 to rotate forward due to the friction force, thereby causing the vertical plate clamping piece 41 to rotate forward. Stop clamping the vertical plate 57 and rotate it to be parallel to the connecting plate clamping plate 40 to avoid blocking the welding position, and due to the periodic setting of the first screw nut 44, only one group of vertical plate clamping plates 41 is loosened at the same time, and since the movement of the welding robot arm 4 is related to the rotation of the vertical plate clamping plates 41, when the welding robot arm 4 moves, the vertical plate clamping plates 41 located in front of the welding robot arm 4 will be opened in advance and pressed against the connecting plate clamping plates 40, which will not hinder the welding of the welding robot arm 4 and make the welding work smoother.
