Description

Technical Field

[0001] The utility model relates to the technical field of welding manipulators, and specifically relates to a full-automatic welding robot arm. Background Technique

[0002] With the progress and development of technology, welding is widely used in various industries. Since manual welding requires workers to perform high-frequency reciprocating operations and there are certain safety hazards, and because it requires long-term hand-held operations, the traditional manual welding method is gradually replaced by robotic arms, thus better ensuring the safety of construction workers during work.

[0003] For an automatic welding robot arm device, refer to the patent number: CN218050999U, a welding torch for an automated welding robot arm, which can achieve that through the setting of a fixing component, when the equipment is working, due to the damage of the welding tip and the replacement of models, the welding tip can replace manual work, so as to meet the requirement that the welding tip can replace the corresponding model for welding gaps of different sizes, thereby improving the working efficiency of the equipment.

[0004] However, this welding robot arm does not have a function of shielding and protecting the welding head. Since the existing welding head generates a large amount of sparks in the welding contact area with the workpiece during welding work, too many flying sparks will pose a certain safety hazard to the working environment of the robot arm and may burn the staff, etc.

[0005] Therefore, we propose a full-automatic welding robot arm. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] Please refer to Figures 1 - 5, a fully automatic welding robotic arm, including a frame body 1. A driving motor 2 is fixedly installed on the front surface of the frame body 1. A robotic arm 3 is rotatably arranged between the front and rear inner walls of the frame body 1. A welding assembly 4 is arranged on the left surface of the robotic arm 3. A welding head 5 is arranged on the left surface of the welding assembly 4. Telescopic cylinders 6 are fixedly installed on both the upper and lower surfaces of the robotic arm 3. The output end of the telescopic cylinder 6 is fixedly connected to a fixing frame 7. A first bolt 8 is movably installed on one side of the fixing frame 7 away from the center of the robotic arm 3. Arc-shaped tubes 9 are movably sleeved on both the upper and lower sides of the outer surface of the welding assembly 4. A mounting plate 10 is fixedly installed on the right surface of the arc-shaped tube 9. A fireproof cloth 11 is wound on the inner surface of the arc-shaped tube 9. Baffles 12 are fixedly installed on both the left and right inner walls of the arc-shaped tube 9. Two second bolts 13 are movably installed on the inner surface of the baffle 12.

[0027] Specifically, through the cooperation among structures such as the frame body 1, the driving motor 2, the robotic arm 3, the welding assembly 4, the welding head 5, the telescopic cylinder 6, the fixing frame 7, the first bolt 8, the arc-shaped tube 9, the mounting plate 10, the fireproof cloth 11, the baffle 12, and the second bolt 13, the working area of the welding head 5 can be shielded and protected. The fireproof cloth 11 can effectively resist the splashing of sparks. In the later stage, the fireproof cloth 11 can be conveniently replaced, improving the protection efficiency and ensuring the safety of the welding work of the fully automatic welding robotic arm.

[0028] In this implementation scheme: The output end of the driving motor 2 is fixedly connected to the front surface of the robotic arm 3. The driving motor 2, the robotic arm 3, the welding assembly 4, and the welding head 5 are electrically connected.

[0029] Specifically, the driving motor 2, the robotic arm 3, the welding assembly 4, and the welding head 5 are existing structures, and the control circuit can be realized by simple programming by those skilled in the art. It belongs to the common knowledge in the field. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0030] In this implementation scheme: Thread grooves corresponding to the first bolt 8 are opened on the outer walls of the fixing frame 7 and the mounting plate 10. The mounting plate 10 corresponds to the fixing frame 7. Thread grooves corresponding to the second bolt 13 are opened on the inner surface of the baffle 12. The second bolt 13 is in corresponding fit with the fireproof cloth 11. The baffle 12 corresponds to the fireproof cloth 11.

[0031] Specifically, through the forward and reverse assembly and disassembly of the first bolt 8 and the second bolt 13 with the first thread groove and the second thread groove, the arc-shaped tube 9 can be conveniently disassembled, so as to quickly replace the internal fireproof cloth 11.

[0032] Working principle: When the full-automatic welding robot arm is in use, the driving motor 2 on the frame 1 drives the robot arm 3 to rotate and move on the frame 1. The robot arm 3 cooperates with the welding assembly 4 and the welding head 5 to approach the workpiece to be processed, so as to carry out the work. While welding, the telescopic cylinders 6 on both sides can push the fixed frame 7 to drive the mounting plate 10 and the arc-shaped pipe 9 to approach the area of the welding head 5. The welding head 5 is surrounded and protected by the two arc-shaped pipes 9. When the welding head 5 welds the workpiece, sparks fly. The fireproof cloth 11 in the arc-shaped pipe 9 can effectively block the sparks, avoiding a large amount of sparks from splashing within the working range of the robot arm 3, thus carrying out the protection work. When the fireproof cloth 11 needs to be replaced after long-term use, reverse the first bolt 8 to disengage it from the first thread groove on the mounting plate 10 and the fixed frame 7, then the arc-shaped pipe 9 and the mounting plate 10 can be removed. Then reverse the multiple second bolts 13 to disengage them from the second thread grooves on the baffle 12, and remove the fireproof cloth 11. Put in a new fireproof cloth 11. Then the fireproof cloth 11 is limited by the baffle 12. Then, on both sides, reverse the second bolts 13 that are screwed into the second thread grooves to cooperate with the baffle 12 to limit and fix the fireproof cloth 11. Put the mounting plate 10 into the fixed frame 7, and the mounting plate 10 and the arc-shaped pipe 9 can be installed by screwing the first bolt 8 into the first thread groove in the forward direction, so as to carry out the subsequent work of preventing sparks from splashing during welding.

[0033] Embodiment 2

[0034] Please refer to Figure 1 、 Figure 3 On the basis of Embodiment 1, the present invention provides a technical solution:

[0035] In this embodiment: The first limiting rods 14 are fixedly inserted on the front and rear surfaces of the frame 1. The outer surface of the first limiting rods 14 is movably sleeved with a transmission plate 15. The front and rear surfaces of the robot arm 3 are movably installed with support rods 16. One side of the support rod 16 away from the center of the robot arm 3 is fixedly connected with a second limiting rod 17. One side of the support rod 16 close to the center of the robot arm 3 is fixedly connected with a sliding plate 18. Limiting sliding grooves 19 are provided on the front and rear surfaces of the robot arm 3.

[0036] Specifically, through the cooperation between the first limiting rods 14, the transmission plate 15, the support rods 16, the second limiting rods 17, the sliding plates 18, the limiting sliding grooves 19 and other structures, when the robot arm 3 rotates and moves, the transmission plate 15 cooperates with the first limiting rods 14 to link the second limiting rods 17, the support rods 16 and the sliding plates 18, which can provide double support for both sides of the robot arm 3, expand the stress points of the robot arm 3, and thus improve the working stability of the robot arm 3, further ensuring the use stability of the full-automatic welding robot arm.

[0037] In this embodiment: The other end of the transmission plate 15 is movably sleeved on the outer surface of the second limiting rod 17, and the sliding plate 18 is slidably arranged corresponding to the limiting sliding groove 19.

[0038] Specifically, the transmission plate 15 and the first limiting rod 14 can be linked with the second limiting rod 17 through the movement of the robotic arm 3.

[0039] Working principle: When the full-automatic welding robotic arm works, when the driving motor 2 on the frame 1 drives the robotic arm 3 to rotate and move, the robotic arm 3 drives the transmission plates 15 on both sides to move. At the same time, through the limitation of the first limiting rod 14, the transmission plate 15 can drive the second limiting rod 17 to slide the sliding plate 18 in the corresponding direction in the limiting sliding groove 19, so that the transmission plates 15 on both sides do not affect the movement of the robotic arm 3, and can also maintain a certain support for the robotic arm 3, improve the stress point of the robotic arm 3, and thus ensure the stability of the movement of the robotic arm 3.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
