Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an automated weld filling device for steel plate welding. Background Technology

[0002] Steel plate welding is a key process in modern industrial manufacturing. Commonly used welding methods include manual arc welding, gas shielded welding, and submerged arc welding. Among them, gas shielded welding and submerged arc welding are widely used in large-scale steel plate welding production due to their advantages such as high welding efficiency and good weld quality.

[0003] Currently, when welding steel plates, wire feeders are usually used to automatically feed welding wire to fill the weld seam, making welding more labor-saving and efficient. However, the contact tip on the welding gun is usually made of copper, but copper has poor wear resistance. The welding wire will cause great wear at the outlet of the contact tip after being fed in the contact tip for a long time. Therefore, the contact tip needs to be replaced frequently, which increases the cost of use. Summary of the Invention

[0004] This utility model provides an automated weld filling device for steel plate welding. It relies on a ceramic tube for conveying during the process, which improves wear resistance. Moreover, the ceramic tube can be replaced, so when wear occurs and replacement is needed, there is no need to replace the entire conductive nozzle, thus reducing the cost of use.

[0005] In a first aspect, this utility model provides an automated weld filling device for steel plate welding, specifically comprising: a conductive nozzle; a connecting block integrally formed on the top of the conductive nozzle, and an internal hexagon screw threaded to the top center of the connecting block; two first connecting strips fixed on the top left and top right of the conductive nozzle, and two ceramic tubes also installed on the top of the conductive nozzle; a front pressure shell installed on the top right of the conductive nozzle, and a rear pressure shell installed on the top left of the conductive nozzle; and two second connecting strips fixed on the bottom left of the rear pressure shell.

[0006] The second connecting strip is an L-shaped protrusion, and the top left side of the conductive nozzle has two L-shaped guide grooves corresponding to the size of the second connecting strip.

[0007] The conductive nozzle has a semi-cylindrical groove on the top left and top right sides, and a semi-cylindrical groove on the bottom of the front pressure shell and the bottom of the rear pressure shell. The size of the semi-cylindrical groove after it is closed is equal to the size of the ceramic tube. A cylindrical protrusion is also provided at one end of the ceramic tube.

[0008] The front pressure shell has a rectangular protrusion on its left side and the rear pressure shell has a rectangular groove on its right side. After the front and rear pressure shells are installed, the rectangular protrusion on one side will be inserted into the rectangular groove on the connecting block.

[0009] Each ceramic tube has a through-hole on its inner side, and the connecting block also has a hole of the same inner diameter in the middle. After the ceramic tube is installed, the hole on its inner side will be aligned with the hole in the middle of the connecting block.

[0010] The rectangular protrusions on the left side of the front pressure shell and the right side of the rear pressure shell each have a circular hole with an inner diameter equal to the outer diameter of the hexagon socket screw. After the front and rear pressure shells are installed, the circular hole on one side of the rectangular protrusion will be aligned vertically with the mounting hole of the hexagon socket screw.

[0011] The first connecting strip is a T-shaped protrusion, and the bottom of the front pressure shell and the bottom right side of the rear pressure shell are provided with two T-shaped guide grooves corresponding to the size of the first connecting strip.

[0012] This utility model provides an automated weld filling device for steel plate welding, which has the following advantages: In this invention, the ceramic tube is installed inside the conductive nozzle. When feeding the welding wire, the welding wire moves in the round hole in the middle of the ceramic tube. Therefore, the welding wire will not directly cause wear to the copper conductive nozzle. Furthermore, the ceramic tube has stronger wear resistance, which can extend its service life. When the outlet of the ceramic tube is worn significantly, the front and rear pressure shells can be disassembled, and then the ceramic tube can be replaced. When wear occurs and replacement is needed, there is no need to replace the entire conductive nozzle, thus reducing the cost of use. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1 to 6 : This utility model proposes an automated weld seam filling device for steel plate welding, comprising: a conductive nozzle 1; a connecting block 2 integrally formed on the top of the conductive nozzle 1, and an internal hexagon screw 3 threadedly connected to the middle of the top of the connecting block 2; the conductive nozzle 1 is used to feed welding wire and provide conductivity; the connecting block 2 is used to install the internal hexagon screw 3; after the front pressure shell 6 and the rear pressure shell 7 are installed, the internal hexagon screw 3 can be passed through the round hole on the rectangular protrusion plate on one side of the front pressure shell 6 and the rear pressure shell 7 and screwed into the threaded hole on the connecting block 2, thereby firmly locking the front pressure shell 6 and the rear pressure shell 7 in the left and right directions; two first connecting strips 4 are fixed on the top left and top right of the conductive nozzle 1; two ceramic tubes 5 are also installed on the top of the conductive nozzle 1; during assembly, the front pressure shell 6 can be pushed to the left for installation, during which the first connecting strip 4 on the top right of the conductive nozzle 1 will... The front pressure shell 6 is embedded in the T-shaped guide groove at the bottom, thus locking the front pressure shell 6 vertically. Then, the rear pressure shell 7 is pushed to the right for installation. During this process, the first connecting strip 4 on the top left of the conductive nozzle 1 will be embedded in the T-shaped guide groove on the bottom right of the rear pressure shell 7, thus locking the rear pressure shell 7 vertically. When feeding the welding wire, the welding wire will move inside the ceramic tube 5, and the ceramic tube 5 can also improve wear resistance. A front pressure shell 6 is installed on the top right of the conductive nozzle 1, and a rear pressure shell 7 is installed on the top left of the conductive nozzle 1. After the front pressure shell 6 and the rear pressure shell 7 are installed, they can fix the ceramic tube 5. Two second connecting strips 8 are fixed on the bottom left of the rear pressure shell 7. During assembly, the rear pressure shell 7 can be pushed to the right for installation. During this process, the second connecting strip 8 on the bottom left of the rear pressure shell 7 will be embedded in the L-shaped guide groove on the top left of the conductive nozzle 1, thus locking the rear pressure shell 7 vertically.

[0018] In this embodiment, as Figures 1-5As shown, the second connecting strip 8 is an L-shaped protrusion, and the top left side of the conductive nozzle 1 is provided with two L-shaped guide grooves corresponding to the size of the second connecting strip 8. During assembly, the rear pressure shell 7 can be pushed to the right for installation. During this process, the second connecting strip 8 on the bottom left side of the rear pressure shell 7 will be embedded in the L-shaped guide groove on the top left side of the conductive nozzle 1, thereby locking the rear pressure shell 7 in the vertical direction.

[0019] In this embodiment, as Figures 2-6 As shown, a semi-cylindrical groove is provided on the top left and top right sides of the conductive nozzle 1. A semi-cylindrical groove is also provided at the bottom of the front pressure shell 6 and the bottom of the rear pressure shell 7. The size of the semi-cylindrical groove after being closed is equal to the size of the ceramic tube 5. A cylindrical protrusion is also provided at one end of the ceramic tube 5. After assembly, the ceramic tube 5 will fit tightly with the semi-cylindrical grooves on the top of the conductive nozzle 1 and the bottom of the front pressure shell 6 and the rear pressure shell 7. Therefore, the ceramic tube 5 can be firmly limited and prevented from shaking. Moreover, the cylindrical protrusion at one end of the ceramic tube 5 can also prevent it from moving left and right.

[0020] In this embodiment, as Figures 2-6 As shown, a rectangular protrusion is provided on the left side of the front pressure shell 6 and the right side of the rear pressure shell 7. A corresponding rectangular groove is provided on both the left and right sides of the connecting block 2. After the front pressure shell 6 and the rear pressure shell 7 are installed, the rectangular protrusion on one side will be inserted into the rectangular groove on the connecting block 2. Then, the hexagonal screw 3 can be passed through the round hole on the rectangular protrusion on one side of the front pressure shell 6 and the rear pressure shell 7 and screwed into the threaded hole on the connecting block 2, so that the front pressure shell 6 and the rear pressure shell 7 can be firmly locked in the left and right directions.

[0021] In this embodiment, as Figures 2-4 As shown, each ceramic tube 5 has a through-hole on its inner side, and the connecting block 2 also has a hole of the same inner diameter in the middle. After the ceramic tube 5 is installed, the hole on its inner side will be aligned with the hole in the middle of the connecting block 2. When in use, the welding wire will enter the hole in the middle of the ceramic tube 5 and the hole in the middle of the connecting block 2 through the welding gun. Finally, the welding wire will extend outward through the opening at the right end of the ceramic tube 5 and fill the weld, thereby realizing automated welding of the steel plate.

[0022] In this embodiment, as Figures 2-6 As shown, the first connecting strip 4 is a T-shaped protrusion, and the bottom of the front pressure shell 6 and the bottom right side of the rear pressure shell 7 are provided with two T-shaped guide grooves corresponding to the size of the first connecting strip 4. During assembly, the front pressure shell 6 can be pushed to the left for installation. During this process, the first connecting strip 4 on the top right side of the conductive nozzle 1 will be embedded in the T-shaped guide groove at the bottom of the front pressure shell 6, thereby locking the front pressure shell 6 in the vertical direction. Then, the rear pressure shell 7 can be pushed to the right for installation. During this process, the first connecting strip 4 on the top left side of the conductive nozzle 1 will be embedded in the T-shaped guide groove on the bottom right side of the rear pressure shell 7, thereby locking the rear pressure shell 7 in the vertical direction.

[0023] Example 2, based on Example 1, such as Figures 1-6 As shown, each of the rectangular protrusions on the left side of the front pressure shell 6 and the right side of the rear pressure shell 7 has a round hole with an inner diameter equal to the outer diameter of the hexagon socket screw 3. After the front pressure shell 6 and the rear pressure shell 7 are installed, the round hole on one side of the rectangular protrusion will be aligned vertically with the mounting hole of the hexagon socket screw 3. Then, the hexagon socket screw 3 can be passed through the round hole on one side of the rectangular protrusion of the front pressure shell 6 and the rear pressure shell 7 and screwed into the threaded hole on the connecting block 2, thereby firmly locking the front pressure shell 6 and the rear pressure shell 7 in the left and right directions.

[0024] The working principle of this embodiment is as follows: During installation, the conductive nozzle 1 can be screwed onto the welding gun of the wire feeder via the thread on its left end. When welding steel plates is required, the wire feeder can be turned on. The wire feeder will automatically feed the welding wire, which will then pass through the welding gun into the round hole in the middle of the ceramic tube 5 inside the conductive nozzle 1 and the round hole in the middle of the connecting block 2. Finally, the welding wire will extend outward through the opening at the right end of the ceramic tube 5 and fill the weld seam, thereby achieving automated welding of the steel plate. When the outlet position of the ceramic tube 5 of the conductive nozzle 1 shows significant wear after prolonged use and needs to be replaced, the conductive nozzle 1 can be unscrewed from the welding gun first, and then the hex socket screw 3 on the connecting block 2 can be unscrewed. At this time, the hex socket screw 3 will disengage from the round hole on the rectangular protrusion plate on the left side of the front pressure shell 6 and the right side of the rear pressure shell 7. Then, the front pressure shell 6 can be pushed to the right to disassemble, and the rear pressure shell 7 can be pushed to the left to disassemble. At this time, the ceramic tube 5 will be exposed, so the worn ceramic tube 5 can be removed and a new ceramic tube 5 can be installed. After replacement, the front pressure shell 6 can be pushed to the left to install. During the process, the first connecting strip 4 on the top right side of the conductive nozzle 1 will be embedded in the T-shaped guide groove at the bottom of the front pressure shell 6, thereby locking the front pressure shell 6 vertically. Then, the rear pressure shell 7 is pushed to the right for installation. During this process, the first connecting strip 4 on the top left side of the conductive nozzle 1 will be embedded in the T-shaped guide groove at the bottom right side of the rear pressure shell 7, and the second connecting strip 8 on the bottom left side of the rear pressure shell 7 will be embedded in the L-shaped guide groove on the top left side of the conductive nozzle 1, thereby locking the rear pressure shell 7 vertically. Moreover, the ceramic tube 5 will be connected to the top of the conductive nozzle 1 at... The semi-cylindrical grooves at the bottom of the front pressure shell 6 and the rear pressure shell 7 fit tightly together, thus firmly limiting the ceramic tube 5 and preventing it from shaking. Finally, the rectangular protrusions on one side of the front pressure shell 6 and the rear pressure shell 7 are inserted into the rectangular grooves on the connecting block 2. Then, the hexagonal screws 3 can be passed through the round holes on the rectangular protrusions on one side of the front pressure shell 6 and the rear pressure shell 7 and screwed into the threaded holes on the connecting block 2, thereby firmly locking the front pressure shell 6 and the rear pressure shell 7 in the left and right directions. Then, the installation and use can continue.
