[0024] Please see Figures 1-7 This invention proposes a scraper welding machine for a scraper chain used in grain and oil machinery, comprising a base 1, a workbench 2 fixed on the top surface of the base 1, a robotic arm 3 mounted on one side of the top surface of the workbench 2, a welding head 4 mounted on the end of the robotic arm 3, and a support frame 5 fixed to one side of the workbench 2, with an installation ring 6 fixed to the end of the support frame 5; the robotic arm 3 drives the welding head 4 to rotate and move, thereby facilitating the welding of the connection between the chain link and the scraper.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 6The rotating moving mechanism is arranged on the periphery of the mounting ring 6 and is used for welding of the welding head 4. The rotating moving mechanism comprises a gear ring 7 which is rotatably sleeved on the outer surface of the mounting ring 6. The bottom surface of the gear ring 7 is fixed with four mounting rods 8 which are uniformly distributed. The bottom surface of each mounting rod 8 is fixed with a U-shaped supporting plate 9. The bottom surface of the U-shaped supporting plate 9 is hingedly connected with two baffle plates 10. The two sides of the U-shaped supporting plate 9 are fixed with two supporting rods 11. The end portions of the two supporting rods 11 are fixed with U-shaped clamping blocks 12. A connecting shaft 13 is rotatably arranged on the surface of the supporting frame 5. The bottom end of the connecting shaft 13 is fixed with a first gear 14 which is in meshing transmission with the gear ring 7. The top surface of the supporting frame 5 is fixedly arranged with a driving motor 15 which is coaxially connected with the connecting shaft 13. The driving motor 15 drives the connecting shaft 13 to rotate, thereby driving the first gear 14 to rotate, and thereby driving the gear ring 7 to rotate on the mounting ring 6. Before rotation, the worker first places the chain link in the U-shaped supporting plate 9 (on the two baffle plates 10), and then inserts the material to be welded into the two U-shaped clamping blocks 12, so that the bottom of the material to be welded is attached to the surface of the chain link. Then, the U-shaped supporting plate 9 is driven to rotate by the gear ring 7, so that the material to be welded is moved to the welding head 4. The welding head 4 is driven to move by the starting of the mechanical arm 3, thereby welding the connection between the scraper and the chain link. After one welding is completed, the next material is welded by continuous rotation, thereby improving the continuity of the welding of the scraper chain material and improving the welding efficiency of the device. It should be noted that the periphery of the gear ring 7 is provided with a protective frame 31 which is fixed with the surface of the supporting frame 5. The gear ring 7 is protected by the protective frame 31, thereby avoiding the accidental touch of the worker.

[0026] Further, as Figures 3-6The top surface of the workbench 2 is provided with a circular through hole 33, and the circular through hole 33 provides a moving space for the blanking mechanism. The blanking mechanism comprises four fixed blocks 18, which are fixed to one side of the mounting rod 8. One side of the baffle 10 is fixed with a rotating shaft 16, and the end of the rotating shaft 16 is fixed with a second gear 17. The top surface of the fixed block 18 is fixed with a fixed rod 19. The outer surface of the fixed rod 19 is slidably sleeved with an L-shaped sliding block 20. The end of the L-shaped sliding block 20 is fixed with a movable frame 21. The two sides of the movable frame 21 are fixed with a rack 22, which is in meshing transmission with the second gear 17. The blanking mechanism further comprises a plurality of rollers 23, which are rotatably connected to the surface of the L-shaped sliding block 20. The outer surface of the fixed rod 19 is sleeved with a spring 24 matched with the L-shaped sliding block 20. The inner side of the mounting ring 6 is fixed with a pull rod 25, and the end of the pull rod 25 is fixed with an inclined seat 26 matched with the roller 23. After one scraper chain material is welded, the next material to be welded is moved to the welding position by rotation, and the welded material is then rotated. During the rotation process, the roller 23 rolls on the inclined surface of the inclined seat 26, and the roller 23 moves downward with the inclination of the inclined surface, thereby driving the L-shaped sliding block 20 to move downward along the fixed rod 19. In this process, the L-shaped sliding block 20 presses the spring 24 downward, and the L-shaped sliding block 20 also drives the movable frame 21 to move downward, thereby driving the rack 22 to rotate the second gear 17 by ninety degrees, and then driving the baffle 10 to open by ninety degrees through the rotating shaft 16, so that the welded scraper and the chain link are blanked. After the blanking is completed, the roller 23 is separated from the inclined seat 26. At this time, the L-shaped sliding block 20 is reset under the elastic force of the spring 24, thereby resetting the baffle 10, and then the staff puts the materials to be welded into the workbench 2 in sequence. It should be noted that the top end of the fixed rod 19 is fixed with a limiting block 34 matched with the L-shaped sliding block 20, and the L-shaped sliding block 20 is limited by the limiting block 34.

[0027] It should be noted that, as Figure 1 , Figure 6 and Figure 7 The top surface of the workbench 2 is provided with a blanking through hole 27, and the lower portion of the workbench 2 is provided with a collecting assembly. The collecting assembly comprises two L-shaped clamping seats 28 fixed to the bottom surface of the workbench 2 in a symmetrical manner. The lower portion of the workbench 2 is provided with a collecting box 29, and the two sides of the collecting box 29 are fixed with clamping strips 30. The clamping strips 30 are slidably connected with the L-shaped clamping seats 28. After the baffle 10 is opened, the welded scraper and chain link fall into the collecting box 29 under the action of gravity, thereby facilitating the collection of materials. In this way, the collecting box 29 is clamped in the L-shaped clamping seat 28 through the clamping strip 30, thereby maintaining the stability of the collecting box 29.

[0028] Further, as Figure 6The bottom surface of the collecting box 29 is fixedly provided with four universal wheels 32 distributed in a rectangular shape, which facilitates the movement of the collecting box 29.

[0029] Working principle: the staff first places the chain link in the U-shaped supporting plate 9, and then inserts the material to be welded into the two U-shaped clamping blocks 12, so that the bottom of the material to be welded is attached to the surface of the chain link; the driving motor 15 drives the connecting shaft 13 to rotate, thereby driving the first gear 14 to rotate, and driving the gear ring 7 to rotate on the mounting ring 6; then the U-shaped supporting plate 9 is driven by the gear ring 7 to rotate, so that the material to be welded moves to the welding head 4; the welding head 4 is driven by the mechanical arm 3 to move, thereby welding the connection between the scraper and the chain link; after one welding is completed, the next material is welded by continuing to rotate, thereby improving the continuity of the scraper chain material welding and the welding efficiency of the device; the staff can conveniently clean the surface of the scraper and the chain link that have not moved to the welding position, thereby improving the welding quality; after one scraper chain material is welded, the next material to be welded moves to the welding position by rotating, and the welded material is discharged by rotating; in the process of rotating, the roller 23 rolls on the inclined surface of the inclined seat 26, and the roller 23 moves downward along with the inclination of the inclined surface, thereby driving the L-shaped sliding block 20 to move downward along the fixed rod 19; in this process, the L-shaped sliding block 20 presses the spring 24, and the L-shaped sliding block 20 also drives the movable frame 21 to move downward, thereby driving the rack 22 to rotate the second gear 17 by ninety degrees, and then driving the baffle 10 to open by ninety degrees through the rotating shaft 16, so that the welded scraper and chain link are discharged; after the baffle 10 is opened, the welded scraper and chain link fall into the collecting box 29 under the action of gravity; after the discharging is completed, the roller 23 is separated from the inclined seat 26, and the L-shaped sliding block 20 is reset under the elastic force of the spring 24, thereby resetting the baffle 10, and then the staff puts the material to be welded into the device in sequence.

[0030] The driving motor 15 can be purchased on the market and is separately provided with a power supply, which belongs to mature technology in the field and has been fully disclosed, so the description is not repeated here.
