Description

Technical Field

[0001] The invention relates to the field of welding, in particular to a welding mechanism for air cap processing. Background Art

[0002] Welding uses energy to disrupt the atomic bonds on a workpiece's surface, causing them to rearrange and form chemical bonds, ultimately achieving a metallurgical or physical bond. With advances in welding technology, intelligent welding systems, such as intelligent welding robots, have gradually entered the industry. When machining air caps, intelligent welding robots are often used to weld the cap and four mounting claws.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The present invention provides a technical solution: Figures 1-8A welding mechanism for air cap processing is shown, comprising a welding table 1 and an intelligent welding robot 7 fixedly mounted on the upper rear end of the welding table 1. Since welding by controlling the intelligent welding robot 7 is a prior art and has been widely used, it is not elaborated on here. A vertical pole 3 is fixedly mounted on the front upper end of the welding table 1, and the vertical pole 3 serves as a support and guide. A positioning tray 4 is coaxially fixedly mounted on the upper end of the vertical pole 3, and the positioning tray 4 serves to support the cap 36. A synchronous sleeve 14 is slidably mounted on the outer surface of the vertical pole 3. Four brackets 5 are fixedly mounted in a circular array with the vertical pole 3 as the center on the upper end of the welding table 1. Two support guide frames 12 are symmetrically fixedly mounted on the ends of the brackets 5. The brackets 5 serve to The guide frame 12 is used for fixing. The guide frame 12 is arranged in an arc surface relative to one end of the positioning tray 4, so that the end of the guide frame 12 can fully press against the outer surface of the cap 36 to position it. A push plate frame 9 is slidably installed between the two guide frames 12. The guide frame 12 plays a role in guiding the push plate frame 9. A synchronous frame 10 is rotatably installed between the push plate frame 9 and the synchronous sleeve 14. The opposite sides of the two guide frames 12 are fixedly installed with a plate hopper 6. The descending synchronous sleeve 14 drives the synchronous frame 10 to move, and then drives the four push plate frames 9 to slide synchronously between the two guide frames 12, so as to simultaneously push the mounting claws 37 at the bottom layer of the four evenly distributed plate hoppers 6. The internal space of the plate hopper 6 is aligned with the mounting claws. 37 is adapted to ensure that the mounting claw 37 does not shake when it is placed in the plate hopper 6. A bucket core 17 is provided on the inner side of the plate hopper 6. The bucket core 17 fits against the upper end of the push plate frame 9. The bucket core 17 can fit into the mounting groove of the mounting claw 37, allowing the mounting claw 37 in the plate hopper 6 to slide down vertically, and when sliding down, allow the mounting claw 37 to fall accurately on the push plate frame 9. At the same time, one end of the push plate frame 9 fits into the mounting groove of the mounting claw 37, and the bucket core 17 is aligned with the push plate frame 9. One end of the bucket core 17 and the push plate frame 9 is adapted to the mounting groove of the mounting claw 37. When the push plate frame 9 fits into the mounting groove of the mounting claw 37 and pushes the mounting claw 37, the mounting claw 37 can be prevented from running away, thereby ensuring that the mounting claw When 37 is pushed, it shows a linear motion trajectory. A rotating and pressing frame 13 is provided above the two support guide frames 12, and a stripping piece is provided between the rotating and pressing frame 13 and the sheet hopper 6. The distance between the support guide frames 12 and the rotating and pressing frame 13 is adapted to the thickness of the mounting claws 37. Under the pressure of the rotating and pressing frame 13, the mounting claws 37 can be pressed onto the support guide frames 12, so that the mounting claws 37 show a horizontal motion trajectory when pushed. The distance between the upper end surface of the positioning tray 4 and the upper end surface of the support guide frames 12 is adapted to the thickness of the cap 36. When the cap 36 is placed on the positioning tray 4, it can be ensured that the upper end surface of the support guide frames 12 and the upper end surface of the cap 36 are coplanar, so that when the subsequent mounting claws 37 are pushed on the support guide frames 12, they can move smoothly to the cap 36.

[0027] The other end of the push plate frame 9 is embedded with a positioning ear 22, which serves to position the push plate frame 9. A fixed core block 35 is fixedly installed in the middle of the bucket core 17. The end of the fixed core block 35 is fixed to the plate hopper 6, and the fixed core block 35 serves to fix the bucket core 17.

[0028] The stripping parts include a shift frame shaft 33 that passes through the ends of the two shift frame 13 respectively. The shift frame shaft 33 is connected to the plate hopper 6. The shift frame shaft 33 plays the role of connecting the shift frame 13. A connecting shaft 30 is arranged between the two shift frame shafts 33. The connecting shaft 30 is rotatably connected to the plate hopper 6. The upper part of the outer surface of the connecting shaft 30 and one of the shift frame shafts 33 are coaxially inlaid with a synchronous gear 31. The two synchronous gears 31 are meshed with each other. A synchronous belt 32 is connected between the lower part of the outer surface of the connecting shaft 30 and the other shift frame shaft 33 through a pulley. The cooperation between the synchronous gear 31 and the synchronous belt 32 can make the two shift frame shafts 33 rotate in opposite directions, thereby driving the two shift frame 13 to rotate in opposite directions.

[0029] An extension shaft 18 is horizontally installed on the side of the plate hopper 6. One end of the extension shaft 18 and the other shift rack shaft 33 are coaxially inlaid with a bevel gear 28. The two bevel gears 28 are meshed. The bevel gear 28 serves to connect the extension shaft 18 and the other shift rack shaft 33 together. The other end of the extension shaft 18 is coaxially inlaid with a stripping gear 21. The stripping gear 21 is vertically meshed with a tooth plate 19. The tooth plate 19 moves downward, thereby driving the stripping gear 21 on the extension shaft 18 to rotate, and drives the two shift rack shafts 33 to rotate in opposite directions through the bevel gear 28, the synchronous belt 32, and the synchronous gear 31. The outer surface of the vertical rod 3 is slidably installed with a pressure cap 16, and the pressure cap 16 is located in the synchronous sleeve 14, an adaptive spring 15 is wound around the outside of the vertical rod 3, one end of the adaptive spring 15 is fixed to the upper end of the synchronous sleeve 14, and the adaptive spring 15 can adapt to the pressure cap 16 continuing to slide down when the push plate frame 9 is stationary, and the other end of the adaptive spring 15 is fixed to the lower end of the pressure cap 16. Four stripping press frames 11 are fixedly installed in a circular array on the outer surface of the pressure cap 16, and a pressure ring 20 is fixedly installed at the end of the stripping press frame 11. The stripping press frame 11 plays a role in supporting the pressure ring 20, and a boss 23 extends from the lower part of the tooth plate 19. The pressure ring 20 can press the boss 23 to drive the tooth plate 19 to move downward, and the pressure ring 20 is located above the boss 23.

[0030] The outer surface of the extension shaft 18 is rotatably installed with an extension frame 8, one end of the extension frame 8 is fixed to the plate hopper 6, and the tooth plate 19 is slidably installed on the other end of the extension frame 8, and the extension frame 8 plays a role in supporting the extension shaft 18 and guiding the tooth plate 19. The outer surface of the shifting frame shaft 33 is rotatably installed with a shaft seat 34, and the end of the shaft seat 34 is fixed to the plate hopper 6, and the shaft seat 34 plays a role in supporting the shifting frame shaft 33. The lower end surface of the shaft seat 34 and the lower end surface of the shifting frame 13 are coplanar. On the one hand, it can prevent the shifting frame shaft 33 from hindering the mounting claw 37 from being pushed. On the other hand, when the mounting claw 37 is just pushed out of the plate hopper 6, the shaft seat 34 can also press the mounting claw 37 on the guide frame 12 for movement.

[0031] A servo push cylinder 2 is installed through the upper end of the welding table 1. The servo push cylinder 2 is located in front of the vertical rod 3. The output end of the servo push cylinder 2 is fixed to the pressure cap 16. The servo push cylinder 2 plays a role in driving the pressure cap 16 to move.

[0032] A load-bearing rod 24 is provided above the rotating pressure frame 13. Two sliding sleeves 25 are symmetrically and slidingly installed on the outer surface of the load-bearing rod 24. The load-bearing rod 24 serves to allow the sliding sleeves 25 to slide. The lower ends of the two sliding sleeves 25 are respectively rotatably connected to the upper ends of the two rotating pressure frames 13. A reset spring 27 is connected between the two sliding sleeves 25. The reset spring 27 can pull the sliding sleeve 25, thereby driving the two rotating pressure frames 13 to move toward each other to return to the position above the support guide frame 12.

[0033] Two positioning caps 26 are symmetrically inlaid on the outer surface of the bearing rod 24, and the two sliding sleeves 25 are respectively pressed against the opposite sides of the two positioning caps 26. The positioning caps 26 play a role in positioning the pulling position of the sliding sleeves 25. The upper ends of the two sliding sleeves 25 are fixedly installed with pull seats 29, and the end of the reset spring 27 is hung on the end of the pull seat 29. The pull seat 29 serves to facilitate the connection of the reset spring 27.

[0034] During welding, multiple mounting claws 37 are stacked in sequence and placed in four evenly distributed sheet hoppers 6. At this time, the bucket core 17 fits into the mounting groove of the mounting claw 37. At the same time, the end of the push plate frame 9 fits into the mounting groove of the mounting claw 37 of the bottom layer of the sheet hopper 6, and the support guide frame 12 supports the mounting claw 37 of the bottom layer. Then the cap 36 is placed on the positioning tray 4. At this time, the end face of the support guide frame 12 is against the outer surface of the positioning tray 4 to position the positioning tray 4. Then the servo push cylinder 2 works to drive the pressure cap 16 to slide down, and the pressure cap 16 pushes the synchronous sleeve 14 to slide down through the adaptive spring 15, so as to use the sliding synchronous sleeve 14 to drive the synchronous frame 10 to move, and then drive the four push plate frames 9 to slide synchronously between the two support guide frames 12, so as to simultaneously The mounting claws 37 located at the bottom layer in the four evenly distributed sheet hoppers 6 are pushed. At this time, the mounting claws 37 slide on the support guide frame 12 to be pushed out from the inside of the sheet hopper 6. At the same time, the upper end of the push plate frame 9 supports the mounting claws 37 stacked on the upper layer in the sheet hopper 6. The pushed mounting claws 37 will enter between the transfer frame 13 and the support guide frame 12, so that under the guidance of the transfer frame 13 and the support guide frame 12, the pushed mounting claws 37 will have a horizontal straight motion trajectory, so that the welding parts of the four mounting claws 37 can be moved synchronously to the cap 36. At this time, part of the mounting claws 37 is located on the cap 36, and the other part is located between the transfer frame 13 and the support guide frame 12, so that the mounting claws 37 are attached to the cap 36 under the restriction of the transfer frame 13 and the support guide frame 12. When the push plate frame 9 pushes the welding parts of the four mounting claws 37 onto the cap 36 synchronously, the positioning ear 22 will press against the guide frame 12 to limit the push plate frame 9, so that the push plate frame 9 cannot move further. At the same time, the sliding pressure cap 16 just drives the pressure ring 20 on the stripping pressure frame 11 to fit onto the boss 23. When the welding is completed, the servo push cylinder 2 works to drive the pressure cap 16 to continue to slide down. At this time, the push plate frame 9 and the synchronous sleeve 14 remain stationary, adapting to the deformation of the spring 15, allowing the pressure cap 16 to continue to slide down, thereby driving the pressure ring 20 on the stripping pressure frame 11 to press the boss 23, allowing the tooth plate 19 to move down, and then driving the extension shaft 18 The stripping gear 21 rotates, and drives the two shifting frame shafts 33 to rotate in opposite directions through the bevel gear 28, the synchronous belt 32, and the synchronous gear 31, thereby driving the two rotating pressure frames 13 to rotate in opposite directions. At this time, the sleeve 25 slides on the load-bearing rod 24, and the reset spring 27 is deformed to adapt to the movement of the rotating pressure frame 13, so that the rotating pressure frame 13 can be rotated away from the upper end of the mounting claw 37, and then the cap 36 is directly pulled upward to remove the welded cap 36 and the mounting claw 37. Then the servo push cylinder 2 moves in the opposite direction to drive the push plate frame 9 to reset, and at the same time the reset spring 27 restores the deformation to pull the sleeve 25, thereby driving the two rotating pressure frames 13 to move toward each other to be located above the guide frame 12, and then the next cap 36 can be welded.
