Description

Technical Field

[0001] This utility model relates to the field of welding technology, and more specifically, to an automatic slag cleaning device. Background Technology

[0002] In some gas shielded welding equipment, the welding torch is positioned above the worktable and can be raised and lowered via a screw motor or other lifting drive to weld parts on the worktable. A sleeve, a circular, hollow cylinder, is fitted and fixed to the front (bottom) of the welding torch to prevent interference with the workpiece during welding. The sleeve protects the argon gas from diffusing, thus preventing rusting of the high-temperature substrate. However, after several circumferential welds, weld slag adheres to the inside of the sleeve, obstructing the flow of the shielding gas. In existing technology, a hole is made at the top of the worktable, and a cylindrical slag removal head is installed inside the hole. The inner diameter of the hole is larger than the outer diameter of the slag removal head and the sleeve. When slag removal is needed, the lifting drive lowers the welding torch and sleeve, inserting the torch head into the slag removal head, which in turn inserts into the sleeve. This process scrapes and removes the weld slag from the inner wall of the sleeve.

[0003] However, in the above-mentioned technology, during slag removal, welding slag will splash inside the gun shroud, and the residue will be squeezed and pressed to the end of the gun shroud away from the worktable and accumulate, blocking the air outlet. The cleaning effect is not good, and additional manual cleaning is required, which delays the welding time. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides an automatic welding slag cleaning device, comprising a slag cleaning head rotatably mounted on a workbench and capable of being inserted into a welding gun shroud; the top of the slag cleaning head has a mating groove for the bottom end of the welding gun to be inserted into; a spiral auger plate is fixedly provided on the outside of the slag cleaning head, and the outer wall of the spiral auger plate abuts against the inner wall of the welding gun shroud to clean the welding slag on the inner wall of the welding gun shroud.

[0005] Optionally, the top of the slag removal head is provided with a beveled surface.

[0006] Optionally, the outer wall of the slag removal head is provided with a deformation groove that communicates with the docking groove. The deformation groove extends vertically and penetrates the spiral auger blade at the corresponding position.

[0007] Optionally, a connecting shaft is fixedly provided at the bottom of the slag cleaning head, and a drive motor is connected to the connecting shaft. The drive motor is connected to the worktable to drive the slag cleaning head to rotate.

[0008] Optionally, the outer wall of the connecting shaft is symmetrically provided with two mating plane grooves.

[0009] Optionally, the top of the workbench is provided with a hole, the slag removal head is located in the hole and does not protrude from the hole, and the outer diameter of the hole is larger than the outer diameter of the gun holster.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows: 1. The slag removal head can be rotated and inserted into the gun shroud. The spiral auger plate can remove the welding slag on the inner wall of the gun shroud when the slag removal head rotates. The removed welding slag can be located in the spiral groove between the spiral auger plate and the outer wall of the slag removal head. Then the welding slag is discharged from the gun shroud with the spiral auger plate, so that the welding slag is not easily squeezed and left in the gun shroud, and the cleaning is more thorough. 2. The beveled surface makes the tip of the cleaning head pointed, which guides the entire cleaning head as it enters the holster, making it enter the holster more smoothly. 3.

[0013] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-2 This application will be described in further detail.

[0014] This utility model provides an automatic welding slag cleaning device, referring to... Figure 1 and Figure 2The automatic slag cleaning device includes a slag cleaning head 1 and a worktable 2. The top of the slag cleaning head 1 has a mating groove 11 for inserting the bottom end of the welding torch. A spiral auger blade 12 is fixedly mounted on the outside of the slag cleaning head 1, and the slag cleaning head 1 is rotatably mounted on the worktable 2. After the welding torch has been used for a period of time, it will fall to a designated position via a drive mechanism (cross-shaped linear module) to allow the inside of the torch sleeve to absorb lubricating oil. Then, it will move directly above the slag cleaning head 1, and the drive mechanism will drive the welding torch and torch sleeve to descend, causing the slag cleaning head 1 and the spiral auger blade 12 to rotate and insert into the torch sleeve. As the torch sleeve moves downward, the spiral auger blade 12 removes the slag adhering to the inner wall of the torch sleeve. The removed slag is located in the spiral groove between the spiral auger blade 12 and the outer wall of the slag cleaning head 1, and then the slag is discharged from the torch sleeve along with the spiral auger blade 12, preventing slag from being squeezed and remaining inside the torch sleeve, resulting in a cleaner slag removal process.

[0015] Reference Figure 1 and Figure 2 The slag removal head 1 is circular, as is the gun holster. The slag removal head 1 and the spiral auger blade 12 are integrally formed, thereby increasing the connection strength between them. The spiral auger blade 12 exhibits even higher strength when scraping and cleaning the welding slag on the inner wall of the gun holster. In another embodiment, the spiral auger blade 12 can also be welded to the slag removal head 1. Both the slag removal head 1 and the spiral auger blade 12 are made of metal, resulting in high strength.

[0016] Reference Figure 1 and Figure 2 The slag removal head 1 has a beveled surface 13 at its top, forming a pointed shape. As the shroud descends, the top of the slag removal head 1 can more smoothly insert into the shroud, guiding the entire slag removal head 1 and the spiral auger plate 12 smoothly into the shroud. The outer wall of the spiral auger plate 12 abuts against the inner wall of the shroud. As the shroud descends, the slag removal head 1 drives the spiral auger plate 12 to rotate, achieving a rotary propulsion that scrapes and cleans the welding slag adhering to the inner wall of the shroud.

[0017] Reference Figure 1 and Figure 2 The outer wall of the slag cleaning head 1 is provided with a deformation groove 14, which extends vertically and penetrates the top of the slag cleaning head 1, and is connected to the docking groove 11; at the same time, the deformation groove 14 also penetrates the spiral auger plate 12 at the corresponding position. In this way, the slag cleaning head 1 can increase its own deformation capacity and elasticity through the deformation groove 14, so that the spiral auger plate 12 can fit tightly against the inner wall of the gun shroud after being inserted into the gun shroud, making it less likely to have gaps, and thus cleaning the welding slag more thoroughly.

[0018] Reference Figure 1 and Figure 2The bottom of the slag cleaning head 1 is integrally formed with a connecting shaft 15, the outer diameter of which is larger than the outer diameter of the spiral auger blades 12. The connecting shaft 15 is connected to the drive motor 21, which in turn drives the connecting shaft 15 to rotate the slag cleaning head 1 and the spiral auger blades 12. The outer wall of the connecting shaft 15 is symmetrically provided with two mating plane grooves 16. A coupling 22 is fixedly connected to the motor shaft of the drive motor 21 by a set screw. The coupling 22 has a linkage groove on the side near the connecting shaft 15. The connecting shaft 15 is inserted into the linkage groove, and the two mating plane grooves 16 abut against the groove wall of the linkage groove to form a key-like connection. The coupling 22 and the connecting shaft 15 are fixed by a set screw to achieve synchronous rotation.

[0019] Reference Figure 1 and Figure 2 The top of the workbench 2 has a through hole 23. The slag removal head 1 is located inside the hole 23 and does not protrude from it. The outer diameter of the hole 23 is larger than the outer diameter of the holster so that the holster can be smoothly inserted into the hole 23. During slag removal, even if welding slag splashes out, it will be blocked by the inner wall of the hole 23, making it less likely for the welding slag to splash out in large quantities.

[0020] A support plate 24 is fixedly installed on the bottom of the workbench 2 by bolts, and the drive motor 21 is fixedly installed on the support plate 24 by bolts.

[0021] The implementation principle of the automatic slag cleaning device in this application embodiment is as follows: When the welding torch and torch sleeve descend, the top of the slag cleaning head 1 is pointed, so it can be smoothly inserted into the torch sleeve. At this time, since the bottom of the welding torch is round, the bottom of the welding torch will also be inserted into the docking groove 11. As the torch sleeve descends, the drive motor 21 can drive the slag cleaning head 1 to rotate and spiral forward. The spiral auger blade 12 is inserted into the torch sleeve and will fit tightly against the inner wall of the torch sleeve, removing the welding slag adhering to the inner wall of the torch sleeve. The removed welding slag can be located in the spiral groove between the spiral auger blade 12 and the outer wall of the slag cleaning head 1. Then the welding slag is withdrawn from the torch sleeve together with the spiral auger blade 12, so that the welding slag is not easily squeezed and left in the torch sleeve. During the cleaning process, since the torch head is inserted into the docking groove 11, the welding slag is not easily splashed into the docking groove 11.
