Description

Technical Field

[0001] The present invention specifically relates to the field of welding technology, and more specifically, to a fitting welding device. Background Art

[0002] Welding technology has become an indispensable key technology in modern manufacturing, and is widely used in many fields such as automobiles, aerospace, ships, construction, energy, electronics, etc.; with the continuous emergence of new materials and new structures, higher requirements are put forward for welding technology, which promotes the continuous innovation and development of welding technology; for example, in the field of new energy vehicles, the requirements for technologies such as welding of aluminum alloy wheels are getting higher and higher; in the aerospace field, the welding connection technology for advanced composite materials is also constantly being explored and studied;

[0003] A wheel usually consists of two parts: a rim and a spoke. After the steel wheel rim is coiled, flash butt welding technology is generally used for welding, and the welding of the rim and the spoke mostly uses argon-rich gas shielded welding or CO2 welding technology; aluminum wheels can be welded by welding technology to weld the rim and the spoke together.

[0004] When welding the existing wheels to the rim and the spoke, friction welding technology is usually used for welding. In this way, during welding, heat is generated by the mutual friction of the contact surfaces of the rim and the spoke to achieve the welding effect. In this way, during welding, during the friction process, deformation may occur between the rim or the spoke, and the dimensions of the rim and the spoke cannot be effectively guaranteed; moreover, when the rim and the spoke are in friction, flash will be generated, which needs to be removed in a subsequent process, which increases the processing procedures and costs; when the traditional rim and spoke are welded, they need to be placed manually. After the placement is completed, a clamping device is used to clamp and fix them. Such a feeding method results in low work efficiency, and during docking, it is easy to cause the rim and the spoke to shift, and the welded rim and spoke will affect the overall quality of the wheel.

[0005] After retrieval, Chinese Patent Publication No. CN201720466139.4 discloses a new type of wheel synthesis welding device; including a welding machine body; a connecting plate is fixedly connected to the bottom of the inner wall of the welding machine body; one side of the top of the connecting plate is rotatably connected to a mounting plate through a hinge; the other side of the top of the connecting plate is fixedly connected to an electric telescopic rod, and the extending end of the electric telescopic rod is fixedly connected to a wedge-shaped block; the top of the wedge-shaped block is slidably connected to the bottom of the mounting plate, and a clamping device is fixedly connected to the top of the mounting plate; a control switch is arranged on the front of the welding machine body; a welding head is arranged on the top of the inner wall of the welding machine body through a movable rod; the welding head is electrically connected to an external power supply through the control switch;

[0006] When the welding device in the above patent welds a wheel, the wheel to be welded is placed on the mounting plate. The rim and the spoke need to be placed on the mounting plate manually. In this way, a long installation time and debugging time are required for the placement, which greatly reduces the working efficiency of the equipment. Moreover, when welding, to ensure the fit between the rim and the spoke, precise docking of the welding position is required. When docking manually, it is easy to cause deviation, and the welding quality of the wheel cannot be effectively guaranteed. Summary of the Invention

[0007] The purpose of the present invention is to provide an accessory welding device. In this device, the spoke is transported to the bottom of the suction cup through the transport component and effectively adsorbed through negative pressure. The rim is placed on the clamping component by the mechanical gripper. When welding, the electric push cylinder is used to move the welding torch downward. The T-shaped rod installed on the welding torch drives the L-shaped plate to synchronously drive the connecting plate downward, and the connecting plate drives the moving rod downward. When the moving rod moves downward, the first tooth on the outer side of the bottom first meshes with the second gear, causing the second gear to drive the worm and the turbine to rotate. The third gear coaxially arranged with the turbine meshes with the toothed plate, causing the moving plate to rise. In this way, the entire feeding component moves upward a certain distance, realizing the separation between the spoke and the transport component, and at the same time avoiding interference with the spoke when the feeding component flips. The moving rod continues to descend, causing the second tooth to mesh with the first gear, and the guide wheel drives the adjusting plate to move through the L-shaped swing rod and the pull rod. Through the movement of the adjusting plate, the fixing rod rotates the suction cup 90° through the fixing frame, thereby moving the spoke to the position where the rim needs to be welded, and effectively realizing the welding effect of the rim and the spoke by the welding torch; to solve the problems in the above background technology.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the present invention, during use, the wheel spokes are transported to the bottom of the suction cups through the transmission component, and the suction of the wheel spokes is achieved through the negative pressure of the suction cups. After the suction is completed, the electric push cylinder causes the T-shaped rod to descend. When the T-shaped rod descends, the first slider drives the L-shaped plate to descend synchronously. At this time, the connecting rod on the L-shaped plate causes the connecting plate to move downward along the slide rail through the second slider;

[0021] 2. In the present invention, during the descent of the connecting plate, the first teeth on the outer side of the bottom of the moving rod penetrate the square groove formed on the moving plate and are meshed with the second gear. The second gear is installed on the worm, so that the worm drives the turbine to rotate. The third gears at both ends of the rotating shaft installed on the turbine are meshed with the toothed plate in the C-shaped frame, so that the toothed plate drives the moving plate to move upward, and the moving plate moves the entire feeding component upward;

[0022] 3. In the present invention, when the entire feeding component moves upward, the suction cups separate the wheel spokes from the transmission component, which ensures the stability during feeding and avoids the transmission component from blocking the wheel spokes when the suction cups rotate. After the first teeth are separated from the second gear, the self-locking between the turbine and the worm is used to prevent the moving plate from descending;

[0023] 4. In the present invention, after the first teeth are separated from the second gear, the second teeth on the moving rod are meshed with the first gear, so that the first gear drives the guide wheel to rotate. The roller in the track groove formed on the guide wheel drives the bottom of the L-shaped swing rod to tilt upward. The L-shaped swing rod pushes the swing rod through the pull rod and the clamp block. The bottom of the swing rod is movably installed with the fixed plate through the connecting rotating rod, and the other end is movably installed with the adjusting plate through the fixed rod, so that the roller connected to the other end of the adjusting plate rolls along the double-round head groove formed inside the rectangular block;

[0024] 5. In the present invention, when the adjusting plate rotates, the fixed rod drives the fixed frame to drive the suction cup on the mounting plate to rotate by 90°, so as to transfer the adsorbed spoke to the surface of the rim fixed by the clamping assembly. At this time, the electric push cylinder moves the welding torch to the welding position through the T-shaped rod; after the suction cup rotates by 90°, when the first slider and the L-shaped plate descend again, the connecting plate and the second slider no longer move, so that the L-shaped plate squeezes the spring sleeved on the connecting rod to achieve compensation for the displacement of the welding torch. During the welding process, the welding angle of the welding torch can be adjusted by the rotating cylinder, and the clamping assembly can also adjust the angle.

[0025] 6. In the present invention, during welding, first, spot welding is performed between the edge of the spoke and the rim by the welding torch. The fixed frame and the mounting plate are movably installed, which effectively prevents the suction cup from separating from the spoke when the clamping assembly rotates. To avoid the trachea of the suction cup from getting knotted, the trachea is connected through a rotary joint. After fixation, multiple suction cups lose pressure and separate from the spoke. At this time, the welding angle between the rim and the spoke can be effectively adjusted by the clamping assembly to meet welding at different angles. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Wherein, the first gear 617 is coaxially arranged with a guide wheel 61; a track groove 610 is opened on the side of the guide wheel 61 far from the first gear 617; the track groove 610 is cooperatively installed with an L-shaped swing rod 618 through a runner; one end of the L-shaped swing rod 618 far from the runner is movably connected with a clamping block 615 through a pull rod 616; the clamping block 615 is slidably installed on a swing rod 613; one end of the swing rod 613 is movably installed with a fixing plate 60 through a connecting rotating rod 614; one end of the swing rod 613 far from the connecting rotating rod 614 is movably installed with one end of an adjusting plate 612 through a fixing rod 619; a fixing frame 63 is fixedly installed at the end of the fixing rod 619 far from the adjusting plate 612; an installation plate 64 is movably installed at the bottom of the fixing frame 63; suction cups 62 are cooperatively installed at the four corners of the installation plate 64;

[0045] A T-shaped rod 54 is fixedly installed at the top of the L-shaped plate 510; wherein, a rotating cylinder 52 is fixedly installed at the end of the T-shaped rod 54 far from the L-shaped plate 510; a welding torch 51 is fixedly installed on the rotating rod of the rotating cylinder 52 through a mounting bracket; a guide rod 59 is arranged between the T-shaped rod 54 and a top plate 516; a round hole for the connecting rod 515 to penetrate through is also opened on the T-shaped rod 54; the top plate 516 is arranged on the top of the slide rail 511 and is fixedly installed with the vertical plate 50; an electric push cylinder 53 is fixedly installed on the top plate 516; the push rod of the electric push cylinder 53 is fixedly installed with the T-shaped rod 54.

[0046] By adopting the above technical solution, during use, the spoke is transported to the bottom of the suction cup 62 through the transport assembly 2, and the spoke is adsorbed by the negative pressure of the suction cup 62. After the adsorption is completed, the electric push rod 53 causes the T-shaped rod 54 to descend. When the T-shaped rod 54 descends, the first slider 512 drives the L-shaped plate 510 to descend synchronously. At this time, the connecting rod 515 on the L-shaped plate 510 causes the connecting plate 58 to move downward along the slide rail 511 through the second slider 513;

[0047] Please refer to Figure 1-14 ; In this embodiment, the feeding assembly 6 further includes a rectangular block 68; the rectangular block 68 is fixedly installed on the top of the fixing plate 60, and among them; a through double-round head groove 69 is formed inside the rectangular block 68; a roller 611 is movably installed in the double-round head groove 69; the roller 611 is movably installed at one end of the adjusting plate 612 away from the fixing rod 619 through a rotating rod;

[0048] In this embodiment, a fixing cylinder 65 is sleeved on the fixing rod 619 between the swing rod 613 and the fixing frame 63; the fixing cylinder 65 is fixedly installed with the swing rod 613; the inside of the fixing cylinder 65 is matched with the fixing rod 619 through a bearing;

[0049] By adopting the above technical solution, during the downward movement of the connecting plate 58, the first tooth 56 on the outer side of the bottom of the moving rod 55 penetrates through the square groove formed in the moving plate 71 and meshes with the second gear 710. The second gear 710 is installed on the worm 79, so that the worm 79 drives the turbine 78 to rotate. The third gears 76 at both ends of the rotating shaft 77 on which the turbine 78 is installed mesh with the toothed plate 75 in the C-shaped frame 74, so that the toothed plate 75 drives the moving plate 71 to move upward, and the moving plate 71 moves the feeding assembly 6 upward as a whole;

[0050] Furthermore, when the feeding assembly 6 moves upward as a whole, the suction cup 62 separates the spoke from the transport assembly 2, which can ensure the stability during feeding and avoid the situation that the transport assembly 2 blocks the spoke when the suction cup 62 rotates. After the first tooth 56 is separated from the second gear 710, due to the self-locking between the turbine 78 and the worm 79, the situation of the moving plate 71 descending is avoided;

[0051] In this embodiment, the feeding assembly 6 further includes a first upright post 66 and a second upright post 67; the first upright post 66 and the second upright post 67 are fixedly installed on the moving plate 71 with the bottom of the fixing plate 60; four corners of the bottom of the moving plate 71 are fixedly installed with telescopic rods 72; the telescopic rods 72 are movably installed inside the fixed support rods 73; a bottom plate 70 is fixedly installed between the fixed support rods 73;

[0052] Both ends of the described bottom plate 70 are fixedly installed with C-shaped frames 74; inside the C-shaped frames 74, rack plates 75 are slidably installed; the rack plates 75 are engaged with third gears 76; the two third gears 76 are coaxially arranged through a rotating shaft 77; the rotating shaft 77 is cooperatively installed with the bottom plate 70 through a pedestal bearing; a turbine 78 is also cooperatively installed on the rotating shaft 77;

[0053] By adopting the above technical solution, after the first tooth 56 is separated from the second gear 710, the second tooth 57 on the moving rod 55 is engaged with the first gear 617, so that the first gear 617 drives the guide wheel 61 to rotate. The roller in the track groove 610 opened on the guide wheel 61 drives the bottom of the L-shaped swing rod 618 to tilt upward. The L-shaped swing rod 618 pushes the swing rod 613 through the pull rod 616 and the clamp block 615. The bottom of the swing rod 613 is movably installed with the fixed plate 60 through a connecting rotating rod 614, and the other end is movably installed with the adjusting plate 612 through a fixed rod 619, so that the roller 611 connected to the other end of the adjusting plate 612 rolls along the double-round head groove 69 opened inside the rectangular block 68;

[0054] Furthermore, when the adjusting plate 612 rotates, the fixed rod 619 drives the fixed frame 63 to realize that the mounting plate 64 drives the suction cup 62 to rotate by 90°, so as to transfer the adsorbed wheel spoke to the surface of the wheel rim fixed on the clamping assembly 4. At this time, the electric push cylinder 53 moves the welding torch 51 to the welding position through the T-shaped rod 54;

[0055] In this embodiment; the turbine 78 is meshed and connected with a worm 79; a second gear 710 is also cooperatively installed on the worm 79; the second gear 710 is engaged with the first tooth 56 on the moving rod 55; a square groove for the moving rod 55 to penetrate through is opened on the moving plate 71;

[0056] The feeding assembly 6 is provided with a transmission assembly 2 on one side; one end of the transmission assembly 2 is located at the bottom of a plurality of suction cups 62; the transmission assembly 2 is fixedly installed with the base 3; a clamping assembly 4 is also fixedly installed on the base 3; the clamping assembly 4 is located at the bottom of the welding torch 51;

[0057] By adopting the above technical solution, after the suction cup 62 rotates by 90°, when the first slider 512 and the L-shaped plate 510 descend again, the connecting plate 58 and the second slider 513 no longer move, so that the L-shaped plate 510 squeezes the spring 514 sleeved on the connecting rod 515, realizing the compensation of the displacement of the welding torch 51. During the welding process, the welding angle of the welding torch 51 can be adjusted through the rotary cylinder 52, and the clamping assembly 4 can also realize the angle adjustment;

[0058] Furthermore, during welding, the edge of the spoke and the rim are first spot-welded by the welding gun 51, and the fixing frame 63 and the mounting plate 64 are movably installed, which effectively ensures that the suction cup 62 will not separate from the spoke when the clamping component 4 rotates. In order to avoid the air pipe of the suction cup 62 from getting tangled, the air pipe is connected through a rotary joint. After the fixation is completed, the multiple suction cups 62 lose pressure and are separated from the spoke. At this time, the welding angle of the rim and the spoke can be effectively adjusted by the clamping component 4 to meet the welding needs of different angles.

[0059] The working principle of the present invention is as follows: when in use, the wheel spoke is transferred to the bottom of the suction cup 62 through the transmission assembly 2, and the wheel spoke is adsorbed by the negative pressure of the suction cup 62. After the adsorption is completed, the electric push cylinder 53 causes the T-shaped rod 54 to descend. When the T-shaped rod 54 descends, the first slider 512 drives the L-shaped plate 510 to descend synchronously. At this time, the connecting rod 515 on the L-shaped plate 510 enables the connecting plate 58 to move downward along the slide rail 511 through the second slider 513;

[0060] During the process of the connecting plate 58 descending, the first tooth 56 on the outer side of the bottom of the moving rod 55 passes through the square groove provided on the moving plate 71 and meshes with the second gear 710. The second gear 710 is installed on the worm 79, so that the worm 79 drives the turbine 78 to rotate. The third gears 76 at both ends of the rotating shaft 77 installed on the turbine 78 mesh with the tooth plate 75 in the C-shaped frame 74, so that the tooth plate 75 drives the moving plate 71 to move upward, so that the moving plate 71 moves the loading assembly 6 upward as a whole.

[0061] When the loading assembly 6 moves upward as a whole, the suction cup 62 separates the wheel spokes from the transmission assembly 2, which ensures stability during loading and prevents the transmission assembly 2 from blocking the wheel spokes when the suction cup 62 rotates. After the first tooth 56 separates from the second gear 710, the self-locking between the turbine 78 and the worm 79 prevents the moving plate 71 from falling.

[0062] After the first tooth 56 separates from the second gear 710, the second tooth 57 on the movable rod 55 meshes with the first gear 617, causing the first gear 617 to drive the guide wheel 61 to rotate. The roller in the track groove 610 provided on the guide wheel 61 drives the bottom of the L-shaped rocker 618 to tilt upward. The L-shaped rocker 618 pushes the rocker 613 through the pull rod 616 and the clamping block 615. The bottom of the rocker 613 is movably mounted to the fixed plate 60 via the connecting rotating rod 614, and the other end is movably mounted to the adjustment plate 612 via the fixing rod 619, so that the roller 611 connected to the other end of the adjustment plate 612 rolls along the double-round groove 69 provided inside the rectangular block 68.

[0063] When the adjusting plate 612 rotates, the fixed rod 619 drives the fixed bracket 63 to enable the mounting plate 64 to drive the suction cup 62 to rotate by 90°, so as to transfer the adsorbed wheel spoke to the surface of the rim fixed on the clamping assembly 4. At this time, the electric push cylinder 53 moves the welding torch 51 to the welding position through the T-shaped rod 54;

[0064] After the suction cup 62 rotates by 90°, when the first slider 512 and the L-shaped plate 510 descend again, the connecting plate 58 and the second slider 513 no longer move, so that the L-shaped plate 510 squeezes the spring 514 sleeved on the connecting rod 515 to realize the compensation of the displacement of the welding torch 51. During the welding process, the welding angle of the welding torch 51 can be adjusted by the rotary cylinder 52, and the clamping assembly 4 can also realize the angle adjustment;

[0065] During welding, first, the welding torch 51 is used to spot-weld between the edge of the wheel spoke and the rim. The fixed bracket 63 and the mounting plate 64 are movably installed, which effectively prevents the suction cup 62 from separating from the wheel spoke when the clamping assembly 4 rotates. To avoid the trachea of the suction cup 62 from getting knotted, the trachea is connected through a rotary joint. After fixation, multiple suction cups 62 lose pressure and separate from the wheel spoke. At this time, the welding angle of the rim and the wheel spoke can be effectively adjusted by the clamping assembly 4 to meet the welding at different angles.
