Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a welding device for the production of engine support legs. Background Technology

[0002] In the field of modern engine manufacturing, the welding quality of outriggers, as key load-bearing components, directly affects the stability and safety of engine operation.

[0003] Publication No. CN219005122U discloses a support leg welding device, including a base plate, a square tube positioning plate, a clamping plate support block, and a connecting block positioning plate. The square tube positioning plate is fixed to the base plate and has four square tube positioning pins. The clamping plate support block is placed on the base plate. The connecting block positioning plate is L-shaped, and connecting block positioning pins are fixed on its two sides. This device, through the positioning of the square tube positioning plate and the connecting block positioning plate, and by utilizing the positioning pins to engage with the connecting holes on the square tube and the connecting block, fixes the support leg as a whole before welding, resulting in more precise welding, reduced welding errors, and significantly improved welding quality and production efficiency.

[0004] As shown in the above technical solution, although the device achieves initial fixation of the support leg through the cooperation of the positioning pin and the positioning plate, the range of motion of the welding gun is limited by the layout of the base plate and the positioning plate, and cannot achieve free adjustment in three-dimensional space. For special positions such as deep cavities and corners where the support leg connects to the main body, the welding gun is difficult to reach the optimal welding angle, which can easily lead to insufficient weld penetration or weld deviation. Especially when the size of the support leg changes, the layout of the positioning pin needs to be redesigned, resulting in poor adaptability. Utility Model Content

[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] See Figures 1-6 This utility model provides the following two technical solutions:

[0030] First embodiment: A welding apparatus for producing engine outriggers, comprising:

[0031] Workbench 1, Workbench 1 is used to provide a platform for welding the engine;

[0032] The clamping assembly 2 is fixedly installed on the top of the workbench 1. The clamping assembly 2 includes two first slide grooves 21, which are respectively opened on the left and right sides of the top of the workbench 1. A clamping plate 22 is slidably installed in each of the two first slide grooves 21. A first bidirectional lead screw 23 is rotatably installed in the workbench 1. The two clamping plates 22 are respectively threaded onto the two ends of the first bidirectional lead screw 23. A first motor 24 is fixedly installed on the left end of the workbench 1. The output end of the first motor 24 passes through the workbench 1 and is fixedly connected to the first bidirectional lead screw 23. The clamping assembly 2 is used to clamp the engine.

[0033] Two first adjustment components 3 are respectively installed on both sides of the rear end of the top of the worktable 1. Each first adjustment component 3 includes a support column 31, which is fixedly installed at the rear end of the top of the worktable 1. A second sliding groove 32 is opened on the inner end of the support column 31. A first lead screw 33 is slidably installed inside the support column 31. A second motor 34 is fixedly installed on the top of the support column 31. The output end of the second motor 34 passes through the support column 31 and is fixedly connected to the first lead screw 33. A top plate 6 is fixedly installed on the top of the front end of the support column 31. The same second adjustment component 4 is slidably installed on the two first adjustment components 3. The second adjustment component 4 includes a support... The two ends of the support block 41 are slidably installed in the two second slide grooves 32 respectively. The two ends of the support block 41 are threadedly connected to the two first lead screws 33 respectively. An adjusting component 42 is fixedly installed on the top of the support block 41. A third slide groove 43 is opened on the top of the adjusting component 42. A first mounting block 44 is slidably installed in the third slide groove 43. A second lead screw 45 is rotatably installed in the adjusting component 42. The first mounting block 44 is threadedly installed on the second lead screw 45. A third motor 46 is fixedly installed on one end of the adjusting component 42. The output end of the third motor 46 passes through the adjusting component 42 and is fixedly connected to the second lead screw 45. A welding gun 5 is installed on the second adjusting component 4.

[0034] The top of the two first adjustment components 3 is fixedly mounted with the same top plate 6. The top plate 6 is fixedly mounted with a limiting component 7. The limiting component 7 includes two fourth slide grooves 71, which are respectively opened on both sides of the front end of the top plate 6. A second mounting block 72 is slidably mounted at each of the two fourth slide grooves 71. A second bidirectional lead screw 73 is rotatably mounted inside the top plate 6. The two second mounting blocks 72 are respectively threaded onto the two ends of the second bidirectional lead screw 73. A fourth motor 74 is fixedly mounted at one end of the top plate 6. The output end of the fourth motor 74 passes through the top plate 6 and is fixedly connected to the second bidirectional lead screw 73. A first electric telescopic rod 75 is fixedly mounted on each of the two second mounting blocks 72. A limiting block 76 for limiting the engine outriggers is fixedly mounted at the output end of each of the two first electric telescopic rods 75. The limiting component 7 is used to limit the left and right outriggers of the engine.

[0035] The second electric telescopic rod 8 is fixedly installed on the first mounting block 44, and the welding gun 5 is installed at the output end of the second electric telescopic rod 8.

[0036] The first motor 24 drives the first bidirectional lead screw 23 to rotate. Since the two clamping plates 22 are threaded to both ends of the first bidirectional lead screw 23 respectively, and the thread directions at both ends of the first bidirectional lead screw 23 are opposite, when the first bidirectional lead screw 23 rotates, the two clamping plates 22 will slide in opposite directions along the first slide groove 21. The distance between the two clamping plates 22 is controlled by the forward and reverse rotation of the first motor 24 to achieve clamping and fixing of engines of different sizes and avoid workpiece displacement during welding. The second motor 34 drives the first lead screw 33 to rotate. The support block 41 is threaded to the lead screw and slides up and down along the second slide groove 32 to achieve vertical height adjustment of the welding gun 5. The third motor 46 drives the second lead screw 45 to rotate. The first mounting block 44 slides laterally along the third slide groove 43, driving the welding gun 5 to move left and right in the horizontal direction. The two first adjustment components 3 cooperate with the second adjustment component 4 to allow the welding gun 5 to move freely in the vertical plane to meet the height and lateral requirements of different welding positions. The fourth motor 74 drives the second bidirectional lead screw 73 to rotate. The two second mounting blocks 74 2. Slide along the fourth slide groove 71 in opposite directions to adjust the lateral spacing of the limiting block 76. The first electric telescopic rod 75 can extend and retract, driving the limiting block 76 to move up and down. It presses down on the left and right outriggers of the engine from the top to limit the outriggers and prevent them from shaking during welding. By combining the lateral spacing adjustment and vertical pressing, the outriggers are limited, ensuring the stability of the welding position. The second electric telescopic rod 8 is fixed on the first mounting block 44, and its output end can move linearly along the axial direction. By controlling the extension and retraction of the second electric telescopic rod 8, the position of the welding gun 5 in the front and back directions can be precisely adjusted, allowing the welding gun 5 to move closer to or further away from the workpiece more flexibly, achieving three-dimensional precise positioning of the welding position. It works in conjunction with the first adjustment component 3 and the second adjustment component 4 to form a complete adjustment system. When the first adjustment component 3 controls the welding gun 5 to move vertically and the second adjustment component 4 controls the welding gun 5 to move horizontally, the second electric telescopic rod 8 is responsible for the adjustment in the front and back directions. The three work together to enable the welding gun 5 to reach any position in the workspace.

[0037] The second embodiment differs from the first embodiment in that: the output end of the second electric telescopic rod 8 is fixedly mounted with a mounting plate 9, the front end of the mounting plate 9 is rotatably mounted with two rotating shafts 10, each of the two rotating shafts 10 is fixedly mounted with a gear 11, the two gears 11 are meshed together, the rear end of the mounting plate 9 is fixedly mounted with a fifth motor 12, the output end of the fifth motor 12 passes through the mounting plate 9 and is fixedly connected to one of the rotating shafts 10, the other rotating shaft 10 is fixedly mounted with a third mounting block 13, and the welding gun 5 is fixedly mounted on the third mounting block 13.

[0038] Two gears 11 are fixed on two rotating shafts 10 respectively and mesh with each other. When the fifth motor 12 drives one of the rotating shafts 10 to rotate, the gear 11 fixed to it rotates accordingly, driving the other gear 11 and the corresponding rotating shaft 10 to rotate in the opposite direction. The welding gun 5 is fixed on one of the rotating shafts 10 through the third mounting block 13. Therefore, when the rotating shaft 10 rotates, the welding gun 5 will make a circular motion around the axis of the rotating shaft 10, thereby realizing the angle adjustment of the welding gun 5. This allows the welding gun 5 to be precisely rotated and positioned within a certain angle range to adapt to the requirements of different welding positions and welding processes.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] In use, place the engine body in the center of the workbench 1 with the left and right outriggers facing upwards, aligning it with the preset position of the limiting component 7. Start the first motor 24 to rotate forward, driving the first bidirectional lead screw 23 to rotate. The two clamping plates 22 slide towards each other along the first slide groove 21 until they slightly contact the engine body. Start the second motor 34 to drive the first lead screw 33 to rotate, and the support block 41 slides up and down along the second slide groove 32, adjusting the welding gun 5 to a position at the same height as the welding point of the outriggers. Start the third motor 46 to drive the second lead screw 45 to rotate, and the first mounting block 44 slides laterally along the third slide groove 43, aligning the welding gun 5 with the center position of the welding point of the outriggers in the left and right directions. Start the second electric telescopic rod 8. The distance of the welding gun 5 in the front-to-back direction is controlled by the telescopic control; the fourth motor 74 is started, driving the second bidirectional lead screw 73 to rotate, and the second mounting blocks 72 on both sides slide towards each other along the fourth slide groove 71, so that the limiting block 76 is aligned with the top center position of the left and right outriggers of the engine. The first electric telescopic rod 75 is started to extend downward, and the limiting block 76 presses down on the outriggers with constant pressure to prevent shaking during welding; according to the weld type, the fifth motor 12 is started, driving the gear 11 to mesh and drive the rotating shaft 10 to rotate, and the welding gun 5 rotates around the axis to the optimal welding angle; under the drive of the three-dimensional adjustment system, the welding gun 5 moves along the preset trajectory while maintaining a stable angle, and completes the continuous welding of the outriggers and the engine body.
