Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to a welding device for automobile parts. Background Technology

[0002] In the production process of modern car seat frames, multiple reinforcing tubes need to be welded onto them. These reinforcing tubes have significantly different welding positions and shapes, so welding equipment is needed to assist in feeding these reinforcing tubes.

[0003] Chinese patent document CN215361062U discloses a seat frame assembly structure for installation in a micro passenger vehicle, including a backrest frame assembly, a seat cushion frame assembly, and a seat belt assembly. The seat belt assembly includes a seat belt, an upper fixing plate fixed to one side of the upper end of the backrest frame assembly, and a retractor fixed to the back of the base frame assembly on the same side as the upper fixing plate. The upper fixing plate has a square hole for the seat belt to pass through. The back of the backrest frame assembly has a support structure that isolates the seat belt from the seat cushion. The support structure is used to reduce friction between the seat belt and the seat cushion. This invention's upper fixing plate facilitates seat belt installation on the seat when the car does not have a B-pillar. The steel bars restrict the seat belt position, and the L-shaped support plate provides space for the seat belt to move within the seat cushion, reducing friction and extending the seat belt's service life.

[0004] The existing technology has the following problems: Existing car seat frames require the welding of reinforcing tubes at different locations. To avoid affecting the final aesthetics of the car seat, these reinforcing tubes are made of different thicknesses, sizes, and shapes. However, because these reinforcing tubes have different shapes and need to be welded to the same car seat, it is difficult to load them. If a robotic arm is used to grip them, it may be difficult to adapt to the different shapes of the reinforcing tubes, which may lead to misalignment during loading. Summary of the Invention

[0005] The main objective of this invention is to provide a welding device for automotive parts that can effectively solve the problem of difficulty in adapting to reinforcing tubes of different shapes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A welding device for automotive parts includes a base with a cavity, a protective column shell on the upper side of the base, a baffle rotatably connected to the inner side of the protective column shell, a welding mechanism on the rear side of the baffle, a feeding mechanism fixedly connected to the upper side of the base, and a ring platform rotatably connected to the upper side of the base near the edge. The ring platform has several mounting holes communicating with the inner cavity of the base on its upper side, and an adjustment mechanism is provided inside each of the mounting holes. The feeding mechanism includes a suspended frame and a rotating platform with a cavity. The lower side of the suspended frame is fixedly connected to the upper side of the base, and the ring platform is located below the rotating platform.

The inner side of the rotating platform has two gripping components that can only move up and down. Material inlets are provided on the front and rear sides of the base. The seat frame is placed from the front side, and the gripping component takes the reinforcing tube from the rear side. Then, the rotating table rotates on the suspended frame, so that the reinforcing tube moves into the inner side of the protective column shell. The baffle moves inside the protective column shell to close the material inlet on the front side, and then the welding operation is performed.

A guide groove is provided on the inner side of the rotating cylinder. Slides are fixedly connected to the upper and lower sides of the inner side of the base near the rear side, and the retaining sleeve is simultaneously slidably connected to the inner side of the guide groove and the slide. When the rotating cylinder rotates one revolution, the retaining sleeve rises from the bottom to the highest point and then resets. The outer side of the lifting plate is fitted inside the retaining sleeve.

[0012] Preferably, a second transmission rod is rotatably connected to the inner bottom of the mounting platform. The second transmission rod is sleeved inside the threaded tube and does not rotate relative to the threaded tube. A top seat is fixedly connected to the upper end of the threaded tube. A rotating seat passing through its bottom wall is rotatably connected to the lower side of the mounting platform. A linkage gear set is provided between the upper end of the rotating seat and the second transmission rod.

[0013] Preferably, a mechanism ring is fixedly connected to the lower side of the mounting platform, and the mechanism ring is sleeved on the outer side of the rotating seat. A spring-driven top ring is provided on the lower side of the mechanism ring, and a number of annularly distributed pushing blocks are fixedly connected to the upper side of the top ring. A number of annularly distributed clamping blocks are provided on the outer side of the rotating seat. The clamping blocks are used to clamp the outer side of the rotating seat, and when the pushing blocks move upward, they push the clamping blocks to move closer together. A cavity for accommodating the clamping blocks and pushing blocks is opened on the inner side of the side wall of the mechanism ring, and an annular groove for accommodating the rotating seat is opened on the inner bottom of the base.

[0014] Preferably, the upper side of the base is provided with a placement mechanism, which is used to install a clamp for holding the seat frame. The placement mechanism can drive the seat frame to rotate and move back and forth. An indicator block is slidably connected to the front side of the placement platform, and the distance between the indicator block and the lower surface of the placement platform can be manually adjusted.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figures 1-4 As shown, an automotive parts welding device includes a base 1 with a cavity, a protective column shell 2 on the upper side of the base 1, a baffle 3 rotatably connected to the inner side of the protective column shell 2, the baffle 3 moving within the protective column shell 2 by means of electronic control drive, and feeding material when the baffle 3 moves away from the front material inlet, and a welding mechanism 4 is provided on the rear side of the baffle 3, and the welding mechanism 4 is simultaneously moved to the upper position when the baffle 3 closes the front material inlet, the welding mechanism 4 is welded by means of a robotic arm driving a welding gun, and the welding mechanism 4 is a laser welding device; A feeding mechanism 5 is fixedly connected to the upper side of the base 1. A ring platform 6 is rotatably connected to the upper side of the base 1 near the edge. The ring platform 6 rotates on the base 1 in an electrically controlled manner. Several mounting holes 7 are opened on the upper side of the ring platform 6, which communicate with the inner cavity of the base 1. An adjustment mechanism 8 is provided on the inner side of each mounting hole 7. The mounting holes 7 and the adjustment mechanism 8 are fixed in a detachable manner. The feeding mechanism 5 includes a suspended frame 51 and a rotating platform 52 with a cavity. The suspended frame 51 is used to form a gap between the rotating platform 52 and the ring platform 6, so that the ring platform 6 can rotate without being disturbed by the rotating platform 52 or other components of the feeding mechanism 5. The lower side of the suspended frame 51 is fixedly connected to the upper side of the base 1, and the ring platform 6 is located on the lower side of the rotating platform 52. The lower side of the rotating platform 52 is electrically rotatably connected to the upper side of the suspended frame 51. The inner side of the rotating platform 52 is provided with two gripping components 53 that can only move up and down. Material passages are provided on the front and rear sides of the base 1. The seat frame is placed from the front side, the grabbing component 53 takes the reinforcing tube from the rear side, and then the rotating table 52 rotates on the suspension frame 51, so that the reinforcing tube moves into the inner side of the protective column shell 2. The baffle 3 moves inside the protective column shell 2 to close the material passage on the front side, and then the welding operation is performed.

[0021] Example 2, as Figures 5-8 As shown, the gripping component 53 includes a mechanism tube 531 and a clamping module 535. The clamping module 535 is a common tubular clamping device that uses two grippers driven by an electric control to clamp the tube. The outer side of the mechanism tube 531 is slidably connected to the inner side of the rotating table 52, and the mechanism tube 531 passes through the side wall of the rotating table 52 to its outer side. The inner side of the mechanism tube 531 is rotatably connected to a first telescopic rod 532. The first telescopic rod 532 allows an electric cylinder to be installed on the mechanism tube 531, which drives the clamping module 535 to move, thereby adjusting the distance between the clamping module 535 and the rotating table 52. The rear end of the first telescopic rod 532 is installed on the front side of the clamping module 535. The lower side of the rotating platform 52 is rotatably connected to two rotating components 54. The rotating components 54 include a first rotating tube 541 and a second rotating tube 542 that are connected together, and the two cannot rotate relative to each other. The inner side of the rotating platform 52 is rotatably connected to a transmission rod 533. A bevel gear set 534 is provided between the transmission rod 533 and the first telescopic rod 532. The transmission rod 533 drives one bevel gear to rotate, and the first telescopic rod 532 is driven to rotate by the other bevel gear that meshes with it. This ensures that the transmission between the transmission rod 533 and the first telescopic rod 532 is not affected no matter how it moves up or down. The bevel gear set 534 is located inside the mechanism tube 531. A linkage structure is provided between the first rotating tube 541 and the transmission rod 533. A gear ring 543 is provided on the inner side of the mechanism tube 531, and a spur gear 544 that meshes with the gear ring 543 is installed at the lower end of the transmission rod 533. This achieves the purpose of driving the transmission rod 533 to rotate when the first rotating tube 541 rotates. When the mechanism tube 531 rotates, it drives the transmission rod 533 to rotate, which in turn drives the first telescopic rod 532 to rotate through the bevel gear set 534.

[0022] Preferably, the upper side of the first rotating tube 541 is rotatably connected to the lower side of the rotating platform 52 and is driven by a torsion spring. The adjustment mechanism 8 includes a detachable mounting platform 81 containing a cavity installed in the mounting hole 7. The mounting platform 81 and the mounting hole 7 are detachably connected, which can be a flange structure installation. The upper side of the mounting platform 81 is rotatably connected to two left and right rotating rings 82 driven by a torsion spring. The upper side of each of the two rotating rings 82 is rotatably connected to a push block 83 with a ratchet limit. The push block 83 can only rotate unidirectionally on the rotating ring 82. The outer side of each of the two rotating rings 82 is fixedly connected to a lever 84 pushed by an electric cylinder. This electric cylinder can be directly installed on the suspension frame 51. The lower side of the second rotating tube 542 is provided with a protrusion pushed by the push block 83.

[0023] It should be noted that the electric cylinder pushes the lever 84, causing the lever 84 to rotate the mounting platform 81. When the mounting platform 81 rotates, it drives the push block 83 to rotate. The push block 83 pushes the protrusion on the lower side of the second rotating tube 542, causing the second rotating tube 542 to be pushed, which in turn drives the first rotating tube 541 to rotate. This adjusts the deflection angle of the grippers on the two transmission rods 533. By adjusting the initial angle of the push block 83 on the rotating ring 82, it can adapt to reinforcing tubes of different shapes.

[0024] Preferably, a push ring 545 is rotatably connected to the lower side of the rotating table 52, and a top block is provided on the lower side of the push ring 545. A lifting frame 546 is rotatably connected to the outer side of the second rotating tube 542, and it cannot rotate relative to the rotating table 52. A pressure block driven by the top block is provided on the upper part of the lifting frame 546. When the push ring 545 rotates relative to the lifting frame 546, the lifting frame 546 is pushed down. When the push ring 545 rotates, the top block passes through the pressure block, causing the lifting frame 546 to move down, thereby driving the second rotating tube 542 to move down. A drive assembly 55 is provided on the lower side of the rotating platform 52, which is similar to a new type of gear set. A first gear ring is installed on the push ring 545, and a second gear ring that meshes with the first gear ring is provided on the lower side of the suspension frame 51. When the rotating platform 52 rotates, the second gear ring drives the first gear ring, so that the push ring 545 and the second rotating tube 542 rotate relative to each other. This is used to drive the push ring 545 to rotate relative to the rotating platform 52 when the rotating platform 52 rotates.

[0025] Preferably, a ring plate 548 suspended by a vertical rod is fixedly connected to the lower side of the rotating platform 52. A reset assembly 56 for driving the lifting frame 546 to reset is provided on the upper side of the ring plate 548. The reset assembly 56 drives the second rotating tube 542 to move upward in the form of a spring-driven plate. Several annularly distributed electromagnetic plates 547 are fixedly connected to the upper side of the ring plate 548. The electromagnetic plates 547 electromagnetically attract the lower side of the reset assembly 56. When electromagnetically attracted, the second rotating tube 542 is restricted by the electromagnetic plates 547, so that the reset assembly 56 cannot reset the second rotating tube 542.

[0026] It should be noted that when the clamping module 535 is located in front of the rotating table 52, it is in the initial state. The rotating table 52 rotates, so that the clamping module 535 is located behind the rotating table 52. During this period, the drive component 55 drives the push ring 545 to rotate, so that the second rotating tube 542 moves down, thereby allowing the push block 83 to drive the protrusion on the lower side of the second rotating tube 542. After the clamping module 535 grabs the reinforcing tube, the electromagnetic plate 547 is de-energized, so that the second rotating tube 542 is reset. Then the rotating table 52 is reset, completing the loading of the reinforcing tube.

[0027] Example 3, as Figures 9-12 As shown, two lifting components 85 are sleeved on the inner side of the mounting platform 81. The lifting component 85 includes a threaded tube 851 and a push plate 852 threadedly connected to its outer side. The push plate 852 will not rotate relative to the mounting platform 81. The front side of the push plate 852 is slidably connected to the vertical groove on the inner front surface of the mounting platform 81. A transparent strip is embedded in the inner side of the vertical groove to indicate the height of the push plate 852. The inner side of the mounting platform 81 is fitted with a lifting plate 86 that can only move up and down. The lifting plate 86 can be prevented from vibrating up and down by gravity and other means, and it is located below the push plate 852. An auxiliary mechanism 9 is rotatably connected to the inner side of the base 1. The auxiliary mechanism 9 includes a rotating cylinder 91 and a ferrule 94. The outer side of the rotating cylinder 91 is rotatably connected to the inner side of the base 1, and the adjustment mechanism 8 is located inside the rotating cylinder 91. A guide groove 92 is provided on the inner side of the rotating cylinder 91. The guide groove 92 is annular, with one side higher than the other, so as to adjust the height of the ferrule 94. The inner sides of the base 1 are fixedly connected to the upper and lower sides near the rear side of the slide 93, and the ferrule 94 is slidably connected to the guide groove 92 and the inner side of the slide 93. The slide 93 is used to restrict the ferrule 94 so that it can only move up and down. When the rotating cylinder 91 rotates once, the ferrule 94 rises from the bottom to the highest position and then resets. The outer side of the lifting plate 86 is sleeved inside the ferrule 94. When the ferrule 94 is at the lowest position, when the ring platform 6 rotates, it automatically drives the lifting plate 86 to slide into the inner side of the ferrule 94.

[0028] Preferably, a second transmission rod 854 is rotatably connected to the inner bottom of the mounting platform 81. The second transmission rod 854 is sleeved on the inner side of the threaded tube 851 and does not rotate relative to the threaded tube 851. When the second transmission rod 854 is rotated, it can drive the threaded tube 851 to rotate, while not affecting the up and down movement of the threaded tube 851. A top seat 853 is fixedly connected to the upper end of the threaded tube 851. The top seat 853 is used to support the mechanism tube 531 and to increase the height of the clamping module 535. The lower side of the mounting platform 81 is rotatably connected to a rotating seat 856 that passes through its bottom wall. A linkage gear set 855 is provided between the upper end of the rotating seat 856 and the second transmission rod 854. The linkage gear set 855 consists of two meshing gears and is used to drive the second transmission rod 854 through the rotating seat 856.

[0029] It should be noted that rotating the rotating seat 856 is used to control the initial height of the push plate 852. Then, when the mounting platform 81 is rotated to the last side, the lifting plate 86 is engaged inside the sleeve 94, and the rotating cylinder 91 rotates, causing the lifting plate 86 to rise to the highest position. This causes the lifting plate 86 to push the push plate 852 to move the threaded tube 851 upward, thereby adjusting the height of the mechanism tube 531.

[0030] Preferably, a mechanism ring 857 is fixedly connected to the lower side of the mounting platform 81, and the mechanism ring 857 is sleeved on the outside of the rotating seat 856. A spring-driven top ring 858 is provided on the lower side of the mechanism ring 857. The top ring 858 can only approach or move away from the mechanism ring 857. Several annularly distributed pushing blocks 8510 are fixedly connected to the upper side of the top ring 858. Several annularly distributed clamping blocks 859 are provided on the outside of the rotating seat 856. Rubber pads are provided on the clamping blocks 859 to enhance the friction between the clamping blocks 859 and the rotating seat 856 and simultaneously prevent over-clamping. The clamping block 859 is used to clamp the outer side of the rotating seat 856, and when the pushing block 8510 moves upward, it pushes the clamping block 859 to move closer together. The inner side of the side wall of the mechanism ring 857 is provided with a cavity to accommodate the clamping block 859 and the pushing block 8510. The inner bottom of the base 1 is provided with an annular groove 95 to accommodate the rotating seat 856. The inner bottom surface of the annular groove 95, together with the fixing between the mounting hole 7 and the mounting platform 81, makes the clamping block 859 tightly clamp the rotating seat 856 and prevent the rotating seat 856 from moving.

[0031] Example 4, as Figure 11 , Figure 12As shown, a mounting mechanism 10 is provided on the upper side of the base 1. The mounting mechanism 10 includes a rotating module, a moving module, and a fixing module. The rotating module is used to drive the fixing module to move, and can be driven by a motor. The fixing module is used to install the fixture for mounting the seat frame. The moving module can drive the rotating module to move closer to or away from the feeding mechanism 5. The movement can be driven by a gear or rack. The mounting mechanism 10 is used to install the fixture for holding the seat frame. The mounting mechanism 10 can drive the seat frame to rotate and move back and forth. An indicator block 87 is slidably connected to the front side of the placement platform 81, and the distance between the indicator block 87 and the lower surface of the placement platform 81 can be manually adjusted. The adjustment method can be screw adjustment. The bottom of the placement mechanism 10 is provided with a measuring module for detecting the height of the indicator block 87 located on the rear side. The measuring module can use a laser detection sensor. Based on the different heights of the indicator block 87, the distance that the placement mechanism 10 drives the seat frame to move is controlled.

[0032] The working principle of this invention is as follows: First, when the clamping module 535 is located in front of the rotating table 52, it is in its initial state. The rotating table 52 rotates, causing the clamping module 535 to be located behind the rotating table 52. During this period, the driving component 55 drives the pushing ring 545 to rotate, causing the second rotating tube 542 to move downward. This allows the pushing block 83 to drive the protrusion on the lower side of the second rotating tube 542. After the clamping module 535 grips the reinforcing tube, the electromagnetic plate 547 is de-energized, causing the second rotating tube 542 to reset. Then, the rotating table 52 resets, completing the loading of the reinforcing tube. By manually adjusting the position of the pushing block 83, the deflection angle of the clamping module 535 can be quickly adjusted. This makes it easy to adapt and adjust, facilitating the handling of reinforcing tubes of different shapes. Grasp, and finally, rotate the rotating seat 856 to control the initial height of the push plate 852. Then, when the mounting platform 81 rotates to the last side, the lifting plate 86 is engaged inside the sleeve 94, and the rotating cylinder 91 rotates, causing the lifting plate 86 to rise to the highest point. This causes the lifting plate 86 to push the push plate 852, which in turn moves the threaded tube 851 upward to adjust the height of the mechanism tube 531. The measuring module can use a laser detection sensor, which controls the distance the mounting mechanism 10 moves the seat frame by relying on the height of different indicator blocks 87. By adjusting the initial height of the push plate 852, the height of the reinforcing tube is adjusted during the rotation of the rotating cylinder 91. In conjunction with the mounting mechanism 10 and the indicator block 87, the reinforcing tube automatically moves to the position where welding is required.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
