Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, specifically a welding torch support structure for robots. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in various environments, such as outdoors, underwater, and in space. Regardless of the location, welding can pose dangers to operators, so appropriate protective measures must be taken when welding.

[0003] Robotic welding is a common welding method. It involves fixing a welding torch to the end effector of a robot, allowing the robot to drive the torch for welding. Existing robot-welding torch connection structures are relatively complex, and torch angle adjustment generally relies solely on the robot's end effector, resulting in poor positional accessibility and limited operability. For example, patent publication CN217412919U discloses a welding torch holder for an aluminum product processing welding robot. It describes a structure where "a first positioning plate is inserted into the outside of the holder body, a first insert rod enters a first mounting hole, one end of the first insert rod fixes the welding torch, a second insert rod fixes the first positioning plate, a pressure plate is pushed to position and fix one end of the second positioning plate via its second positioning groove, a first magnet and a second magnet attract each other stably, the second magnet is limited to both sides of the first positioning plate, a third positioning plate is limited to the side of the first positioning plate, and a pressure plate limits and fixes the side of the first positioning plate, thus stabilizing the welding torch within the holder body." This demonstrates that the welding torch holder structure is relatively complex and cannot independently adjust the torch angle. Utility Model Content

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

[0026] Please see Figure 1-4 and Figure 7 As shown, this utility model provides a technical solution: a welding torch bracket structure for robots, including a fixed base 1 for mounting the welding torch, a support rod 2 for supporting the fixed base 1, an adapter block 3 connecting the support rod 2 and the fixed base 1, a flange 5 connected to the end of the support rod 2 away from the fixed base 1 and connected to the robot end effector, a collision avoidance device 6 for safety protection between the flange 5 and the support rod 2, and the fixed base 1 being able to rotate relative to the support rod 2; the fixed base 1 includes an upper base 11 and a base 12, the upper base 11 having a semi-circular first slot 111, the base 12 having a semi-circular second slot 121 that cooperates with the first slot 111 to realize the mounting of the welding torch, the side of the base 12 away from the upper base 11 having a connecting protrusion 123 for connecting with the adapter block 3, and a plurality of first bolts 13 connecting the upper base 11 and the base 12.

[0027] In this application, the welding torch support structure is used for the connection between the robot and the welding torch, achieving the fixation and support of the welding torch. Specifically, the fixed base 1 is used for mounting the welding torch, and the support rod 2 connects the fixed base 1 and the flange 5, that is, the welding torch is mounted on the robot's end effector via the flange 5, the support rod 2, and the fixed base 1. The adapter block 3 connects the fixed base 1 and the support rod 2, and facilitates the rotation of the fixed base 1 relative to the support rod 2, enabling angle adjustment of the welding torch mounted on the fixed base 1. A collision avoidance device 6 is installed between the flange 5 and the support rod 2, providing a collision avoidance effect and improving the safety of welding torch use.

[0028] The fixing base 1 includes an upper base 11, a base 12, and a first bolt 13. The first bolt 13 is used to connect the upper base 11 and the base 12. The welding torch can be clamped between the upper base 11 and the base 12 through the first slot 111 on the upper base 1 and the second slot 121 on the base 12, realizing the installation and fixation of the welding torch. The first bolt 13 connects the upper base 11 and the base 12, so that the upper base 11 and the base 12 can hold the welding torch. The connecting protrusion 123 is set on the side of the base 12 away from the upper base 11, which facilitates the connection between the base 12 and the support rod 2 and does not interfere with the connection of the upper base 11. The connecting protrusion 123 is used to cooperate with the adapter block 3. It extends away from the upper base 11 and is set in a semi-circular arc structure, which facilitates the cooperation with the adapter block 3. First, it facilitates the connection between the base 12 and the adapter block 3. Second, it does not interfere with the rotation of the fixing base 1 relative to the support rod 2. By rotating the adapter block 3 relative to the support rod 2, the fixed seat 1 is rotated relative to the support rod 2, thus achieving the rotational connection of the welding gun installed on the fixed seat 1 and realizing the adjustment of the installation angle of the welding gun.

[0029] Please refer to Figure 4 As shown, in one embodiment of this application, the upper seat 11 is provided with a first connecting hole 112 for the first bolt 13 to pass through, and the base 12 is provided with a second connecting hole 122 for the first bolt 13 to be screwed in. The first bolt 13 is installed through the first connecting hole 112 and the second connecting hole 122, ultimately achieving the connection between the upper seat 11 and the base 12. The first connecting hole 112 can be a threaded hole or a smooth hole, facilitating the passage of the first bolt 13; the second connecting hole 122 is a threaded hole, facilitating the connection and fixation of the first bolt 13 to the base 12. The connection method is simple and convenient. After the first bolt 13 passes through the first connecting hole 112, it is screwed into the second connecting hole 122, facilitating the tightening of the first bolt 13 and achieving the fixation of the welding torch.

[0030] Please continue to refer to Figure 4 As shown, in another embodiment of this application, the upper seat 11 is provided with a plurality of first fixing holes 113 that communicate with the first slot 111. The first fixing holes 113 are used to connect screws or pins to further fix the welding gun that is locked between the upper seat 11 and the base 12, thereby ensuring the firmness of the welding gun fixed on the fixing seat 1 and preventing the welding gun from rotating or sliding.

[0031] Please refer to Figure 1 and Figure 4 As shown, in another embodiment of this application, the connecting protrusion 123 is provided with a mounting hole 124, the mounting hole 124 is connected to a second bolt 4, and a stepped nut 14 connected to the second bolt 4 is provided in the mounting hole 124. The mounting hole 124 is a stepped hole, and the fixing seat 1, the support rod 2 and the adapter block 3 are connected by the second bolt 4.

[0032] In this embodiment, the mounting hole 124 is used for the installation of the second bolt 4, connecting the base 12, the adapter block 3, and the support rod 2, and facilitating the rotation of the fixed seat 1. The adapter block 3 has a hole for the second bolt 4 to pass through. The second bolt 4 passes through the support rod 2, the adapter block 3, and the connecting protrusion 123 in sequence, and then is screwed onto the stepped nut 14, thus connecting the base 12, the adapter block 3, and the support rod 2. The mounting hole 124 is a stepped hole, which can cooperate with the stepped nut 14 to limit the movement of the stepped nut 14. At the same time, it can hide the stepped nut 14 within it, improving the aesthetics.

[0033] Please refer to Figure 4 As shown, based on the above scheme, the base 12 is further provided with a second fixing hole 125 that connects to the second slot 121. The second fixing hole 125 is connected to the mounting hole 124. The second fixing hole 125 is used to connect screws, which facilitates further fixing of the welding gun installed between the upper seat 11 and the base 12. At the same time, through the connection between the second fixing hole 125 and the mounting hole 124, the screw connected in the second fixing hole 125 also contacts the stepped nut 14 to limit the rotation of the stepped nut 14 and prevent the stepped nut 14 from falling off.

[0034] Please refer to Figure 4 As shown, in another embodiment of this application, a limiting block 126 protruding outward is provided on one side of the base 12 near the bottom of the second slot 121. By setting the limiting block 126, it can cooperate with the welding gun to limit the position of the welding gun, prevent the welding gun from being installed out of position or prevent the welding gun from rotating, and further improve the installation firmness of the welding gun.

[0035] Please refer to Figure 5 , Figure 6 As shown, based on the above scheme, further, the end of the support rod 2 connected to the fixed seat 1 is provided with a third connecting hole 21 for the second bolt 4 to pass through, and the end of the support rod 2 connected to the anti-collision device 6 is provided with a fourth connecting hole 22. Both the third connecting hole 21 and the fourth connecting hole 22 are stepped holes. The third connecting hole 21 is a smooth hole, facilitating the rotation of the second bolt 4 relative to the support rod 2, which in turn facilitates the rotation of the adapter block 3 relative to the support rod 2, enabling the fixed seat 1 to rotate relative to the support rod 2, thereby achieving angle adjustment of the welding torch. The central axis of the third connecting hole 21 is perpendicular to the central axis of the second slot 121 of the fixed seat 1, facilitating the left and right rotation of the fixed seat 1 relative to the support rod 2, thus achieving angle adjustment of the welding torch relative to the support rod. The stepped holes 21 and 22 serve a limiting function, limiting the installation of the second bolt 4 connected in the third connecting hole 21 and the third bolt 7 connected in the fourth connecting hole 22, and concealing the second bolt 4 and the third bolt 7, improving the structural aesthetics.

[0036] Furthermore, the support rod 2 is provided with an arc-shaped support groove 23 near the third connecting hole 21 for supporting the rotation of the adapter block 3. This groove is used to support and limit the movement of the adapter block 3. The arc-shaped structure facilitates the smooth rotation of the adapter block 3.

[0037] Please refer to Figure 1 As shown, based on the above scheme, further, the side of the anti-collision device 6 near the support rod 3 is provided with a connecting shaft 61 for insertion and connection with the fourth connecting hole 22. Several limiting grooves 62 are provided along the circumferential edge of the connecting shaft 61 on the anti-collision device 6. A third bolt 7 connects the connecting shaft 61 and the fourth connecting hole 22. The connecting shaft 61 of the anti-collision device 6 is used to connect with the support rod 3, and it can be inserted into the fourth connecting hole 22. The connection between the connecting shaft 61 and the third bolt 7 achieves the fixation of the support rod 2, and the support rod 2 can rotate about the connecting shaft 61 as a pivot, achieving rotational adjustment of the support rod 2. The limiting grooves 62 are used to limit the rotation of the support rod 2 relative to the anti-collision device 6. These grooves can be fitted with rod-like structures such as pins, screws, or limiting rods to limit the rotation of the support rod 2.

[0038] Furthermore, several rotating rings 8 are sleeved on the connecting shaft 61, and these rotating rings 8 are disposed within the fourth connecting hole 22. A limiting pin 9 is inserted into one of the limiting grooves 62, and the support rod 2 is provided with a limiting hole 24 for the limiting pin 9 to be inserted. The rotating rings 8 facilitate the rotation of the support rod 2 relative to the connecting shaft 61. The limiting pin 9 is inserted between the limiting groove 62 and the limiting hole 24 to limit the rotation of the support rod 2. The multiple limiting grooves 62 can position and limit the support rod 2 at different angular positions, ensuring that the support rod 2 can be installed in different positions relative to the robot's end effector.

[0039] In this application, the welding torch support structure is simple in structure, which facilitates the installation and angle adjustment of the welding torch, and the adjustment method is simple and easy.
