Description

Technical Field

[0001] The present invention specifically relates to the technical field of welding testing, and in particular to an integrated welding testing device for aluminum alloy accessories. Background Art

[0002] In automobile transmissions, a welded gear set structure is often used, that is, the gear set is mounted on a hollow shaft and welded by welding. This welding method has the advantages of small size, light weight, relatively simple product structure and manufacturing process, high production efficiency and low cost;

[0003] With the development of new energy vehicles, the speed of driving motors is getting higher and higher, and the hollowing of motor shafts has become an inevitable trend. Components welded together by gears and hollow motor shafts can be used to efficiently transmit the power of the motor and meet the power transmission requirements of new energy vehicles.

[0004] At present, the traditional gear and hollow shaft welding is usually carried out by manual welding. In this way, the matching between the gear and the hollow shaft needs to be achieved through a specific fixture, which makes the work efficiency low during welding. In addition, when welding, the welding worker needs to have a high welding level, and during the welding process, the gear and the shaft need to be rotated, which is easy to cause the welding quality to deviate during the welding process, affecting the working efficiency of the gear. In addition, the traditional gear and shaft welding device can only achieve a single welding effect. The welding quality between the gear and the hollow shaft needs to be tested by other auxiliary equipment, which will result in the effect that the equipment cannot be tested continuously during the working process, thereby reducing the working efficiency of the equipment;

[0005] After searching, Chinese patent publication number CN202211330360.9 discloses a post-weld quality inspection device for aluminum alloy components, including a frame, a walking track, a first shooting camera, a second shooting camera, a conveying mechanism and a display device; the walking track is arranged in the frame, and a connecting plate is installed on the walking track, and a mounting disc is rotatably connected to the bottom surface of the connecting plate, and a first shooting camera for photographing the welding points of the aluminum alloy components is provided on the mounting disc, and the first shooting camera is arranged at a non-center position of the bottom surface of the mounting disc, and the fan-shaped protrusion is driven to rotate by controlling the start-up reduction motor, and the mounting disc is driven to rotate by the cooperation of the fan-shaped protrusion and the fan-shaped groove. At this time, the first shooting camera located at the non-center position shows a circular motion, so as to realize a comprehensive shooting and scanning of the cylindrical or annular aluminum alloy components, prevent missed inspections, and improve the shooting and scanning range of different shapes of aluminum alloy components.

[0006] After the welding of the accessories is completed, the device in the above patent uses the first camera and the second camera to photograph and detect the quality of the welding. Although this can achieve the effect of welding quality detection, if the number of aluminum alloy components to be detected is large, the equipment may have low overall detection efficiency due to factors such as shooting speed and image analysis speed, and cannot meet the rapid detection needs in large-scale production. In particular, for some production scenarios that require online real-time detection, it may not be possible to give detection results in time, affecting production progress.

[0021] 1. In the present invention, when in use, the gear to be welded is transmitted through the transmission frame, and is placed on the placement plate in the transmission process by grabbing the first mechanical arm. When the gear is placed through the bottom of the discharge pipe in the feeding assembly, the hollow shaft is sleeved on the positioning rod through the discharge pipe through the feeding assembly to achieve positioning and matching of the gear and the hollow shaft, and then the first sprocket is driven to rotate by the first driving motor to achieve cyclic transmission of the first chains matched on multiple first sprockets;

[0057] By adopting the above technical solution, during welding, the third sprocket 134 needs to be driven to rotate by the second driving motor 133, and the second chain 131 is arranged between the third sprocket 134 and the two rollers 136. The second chain 131 is engaged with the second sprocket 84, so that the second sprocket 84 drives the positioning rod 80 and the placement plate 81 to rotate synchronously. During the rotation of the positioning rod 80 and the placement plate 81, the welding gun 53 is effectively welded along the edge of the gear and the shaft. During the welding process, the harmful gas generated is centrally treated through the connecting pipe.

[0058] In this embodiment, a blanking plate 9 is provided at the bottom of the movable table 70; the blanking plate 9 is fixedly mounted on the bottom of the top plate of the workbench 1 and is arranged in an inclined manner; a second mechanical arm 6 is provided on the workbench 1; the second mechanical arm 6 is arranged at one end of the movable table 70 away from the support frame 71 and is fixedly mounted on the workbench 1;

[0059] Further, after the welding of the gear and the shaft is completed, the transmission of the first chain 85 is realized between the two counters installed on the mounting frame 12 to achieve accurate counting. After the counting is completed, the second mechanical arm 6 moves the accessories welded on the positioning rod 80 and the placement plate 81 into the placement groove 713 opened on the movable platform 70. During the placement of the gear, the self-generated weight of the accessories presses down the top column 74. During the descent of the movable plate 712 at the bottom of the top column 74, the central rotating drum 715 cooperates with the lever 721 accessories inside the fixed plate 78 through the guide groove 716, so that the second gear 710 at the bottom of the rotating drum 715 cooperates with the first tooth plate 711, so that the first tooth plate 711 drives the movable plate 75 to move forward along the guide column 76 through the ear plate, thereby ensuring the stability of the gear in the placement groove 713.

[0062] By adopting the above technical solution, the push rod and the plug 720 are pressed down by the electric push cylinder 718. As the push rod contacts the shaft, the accessory continues to press the top column 74, and the movable plate 75 continues to move forward through the second gear 710. When the electric push cylinder 718 exerts a certain pressure on the shaft of the accessory, the welding strength of the accessory is tested. When the gear and the shaft are separated, the shaft passes through the rotating cylinder 715 and falls onto the blanking plate 9. At this time, the push rod continues to descend, and the plug 720 on the push rod cooperates with the gear to achieve The gear is taken out from the placement groove 713, and the reducer 717 is meshed with the teeth 719 on the side wall of the moving platform 70, so that the moving platform 70 moves toward the second mechanical arm 6. At this time, the gear is separated from the top column 74 in the placement groove 713, and the moving plate 75 moves upward under the action of the first spring 77 on the guide column 76. At this time, the rotating drum 715 flips over, so that the first tooth plate 711 drives the moving plate 75 to move backward, and the semicircular opening on the moving plate 75 is separated from the placement groove 713, which is convenient for the placement of the second mechanical arm 6;

[0063] When the push rod drives the plug 720 to move upward, the top of the gear is separated from the plug 720 by the push rod 722 at the bottom of the top plate of the support frame 71, and the gear passes through the rectangular groove to fall onto the blanking plate 9; the qualified accessories are taken out from the placement groove 713 manually;

[0064] The working principle of the present invention is as follows: when in use, the gear to be welded is transmitted through the transmission frame 3, and is grabbed by the first mechanical arm 2 and placed on the placement plate 81 in the transmission process. When the gear is placed through the bottom of the discharge pipe in the feeding assembly 4, the feeding assembly 4 realizes that the hollow shaft is sleeved on the positioning rod 80 through the discharge pipe, so as to realize the positioning and matching of the gear and the hollow shaft, and then the first drive motor 82 drives the first sprocket 83 to rotate, so as to realize the cyclic transmission of the first chains 85 matched on the multiple first sprockets 83;

[0065] During the transmission process, when the placement plate 81 with the gears and shafts is moved to the inside of the housing 10, the cylinder 11 drives the pressing plate 14 to press down, so as to achieve a close fit between the gears and the shafts, and then the slide plate 51 arranged on one side of the stand 50 drives the support frame 52 to adjust the position of the welding gun 53, so as to ensure the welding quality between the gears and the shafts;

[0066] During welding, the third sprocket 134 needs to be driven to rotate by the second driving motor 133. A second chain 131 is provided between the third sprocket 134 and the two rollers 136. The second chain 131 is engaged with the second sprocket 84 to achieve the synchronous rotation of the positioning rod 80 and the placement plate 81 driven by the second sprocket 84. During the rotation of the positioning rod 80 and the placement plate 81, the welding gun 53 is effectively welded along the edge of the gear and the shaft. During the welding process, the harmful gas generated is centrally treated through the connecting pipe.

[0067] After the welding of the gear and the shaft is completed, the transmission of the first chain 85 is realized between the two counters installed on the mounting frame 12 to achieve accurate counting. After the counting is completed, the second mechanical arm 6 moves the accessories welded on the positioning rod 80 and the placement plate 81 into the placement groove 713 opened on the moving platform 70. During the placement of the gear, the self-generated weight of the accessories presses down the top column 74. During the descent of the moving plate 712 at the bottom of the top column 74, the central rotating drum 715 cooperates with the lever 721 accessories inside the fixed plate 78 through the guide groove 716, so that the second gear 710 at the bottom of the rotating drum 715 cooperates with the first tooth plate 711, so that the first tooth plate 711 drives the moving plate 75 to move forward along the guide column 76 through the ear plate, thereby ensuring the stability of the gear in the placement groove 713.

[0068] Then, the push rod and the plug 720 are pressed down by the electric push cylinder 718. As the push rod contacts the shaft, the accessory continues to press the top column 74, and the moving plate 75 continues to move forward through the second gear 710. When the electric push cylinder 718 exerts a certain pressure on the shaft of the accessory, the accessory is tested. When the gear and the shaft are separated, the shaft passes through the rotating drum 715 and falls onto the unloading plate 9. At this time, the push rod continues to descend, and the plug 720 on the push rod cooperates with the gear to remove the gear from the placement slot 713, and the reducer 7 17 meshes with the teeth 719 on the side wall of the movable platform 70 to realize the movement of the movable platform 70 toward the second robot arm 6. When the push rod drives the plug 720 to move upward, the gear is separated from the plug 720 by the push rod 722 at the bottom of the top plate of the support frame 71. The gear passes through the rectangular groove and falls onto the unloading plate 9. The unloading plate 9 is used to recover the gears and shafts that fail the test. The accessories that pass the water test are manually taken out from the placement groove 713, effectively realizing the effective separation of the products that pass the test and those that fail the test.
