Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and more specifically to a flame plate assembly for connecting a robotic arm. Background Technology

[0002] With the development of technology, welding technology using robots and / or robotic arms has emerged. Therefore, it is necessary to design a fire grid assembly that is compatible with robots and their robotic arms to facilitate flexible welding.

[0003] Traditional flame welding, in pursuit of flexibility, typically designs the ventilation pipes as flexible copper tubes that can deform at will. For example, the patent specification with publication number CN205166108U discloses an adjustable flame grate mechanism assembly, in which the welding nozzle can rotate on the flame nozzle, making it suitable for welding any product and ensuring uniform heating. However, this design presents some problems in today's increasingly automated world. For instance, while freely moving robotic arms can already meet the welding flexibility requirements, collisions during the robotic arm's movement that cause overall structural deformation or changes in nozzle position can further reduce the accuracy of the automated control algorithm. Moreover, the deformed flame grate structure (including the nozzle) is difficult to accurately restore to its pre-collision shape and position. This necessitates adaptive readjustment and resetting of the robotic arm's automated control algorithm, undoubtedly increasing the skill requirements for technicians and raising labor costs for manufacturers. Utility Model Content

[0004] To address the aforementioned technical problems and shortcomings in this field, this utility model provides a fire-gathering assembly for connecting a robotic arm. It can be designed as a disc-type integrated structure, and the connecting seat can be designed to perfectly integrate with the multi-axis rotating disc of the robot or robotic arm, adapting to the working environment without affecting the air delivery.

[0005] The specific technical solution is as follows: A flame arrester assembly for connecting a robotic arm includes a connecting base for connecting the robotic arm, a mounting plate fixedly disposed on the connecting base, a gas path conversion block fixedly disposed on the mounting plate, the gas path conversion block including at least one air inlet and at least one air outlet, one or more connecting plates fixedly disposed on the mounting plate, a gas distribution block fixedly disposed on the connecting plate, the gas distribution block being connected to the air outlet of the gas path conversion block via a gas pipe, and a flame nozzle disposed on the gas distribution block.

[0006] The aforementioned flame plate assembly for connecting the robotic arm is mounted on the robotic arm via a connecting seat. The movement of the robotic arm drives the flame plate assembly to move. During welding, the mixture containing the combustion gas and the auxiliary combustion gas enters the gas path conversion block through the air inlet. Then, the mixture leaves the gas path conversion block through the air outlet, flows to the gas distribution block through the gas pipeline, and finally is ejected from the nozzle on the gas distribution block to form a flame.

[0007] In some embodiments, the burner assembly for connecting the robotic arm, including the connecting seat, the mounting plate, the gas path conversion block, the connecting plate, and the gas distribution block, are all rigid structures. This ensures the stability of the gas path and the corresponding burner positions, preventing deformation upon impact and ensuring the robotic arm control algorithm remains functional. It also eliminates the need for a cumbersome reset process, thereby improving welding efficiency and stability.

One end of the main gas line is open, and the other end is sealed, and the open end of the main gas line is connected to the ventilation pipe. One end of the gas branch is connected to the main gas line, and the other end is connected to the burner.

[0012] In some embodiments, the ventilation pipe of the fire-generating assembly for connecting the robotic arm is a copper pipe with flexible and bendable characteristics.

There are two connecting plates, namely the first connecting plate and the second connecting plate; There are two gas distribution blocks, namely a first gas distribution block and a second gas distribution block.

The second gas distribution block is equipped with a second burner.

[0015] In some embodiments, the fire-generating assembly for connecting the robotic arm has the first air outlet and the second air outlet located on the left and right sides of the air path conversion block, respectively. The first connecting plate is located on the left side of the mounting plate, and the second connecting plate is located on the right side of the mounting plate, with the first connecting plate and the second connecting plate being arranged opposite to each other; The first gas distribution block and the second gas distribution block are arranged opposite to each other.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model is used for a flame arrestor assembly for connecting robotic arms.

It will not undergo serious deformation after a collision, and the position of the flame nozzle will not change. There is no need for cumbersome position adjustment operations, which greatly improves welding efficiency and welding stability. Attached Figure Description

[0021] In this embodiment, the first gas distribution block 51 and the second gas distribution block 52 adopt the same structural design and are connected to the corresponding connecting plate, burner, and ventilation pipe using the same connection relationship. Taking the second gas distribution block 52 as an example, see... Figure 2The second gas distribution block 52 is provided with a guide groove 521. The second connecting plate 42 and the guide groove 521 are connected in cooperation. The upper and lower positions of the second gas distribution block 52 on the second connecting plate 42 are adjustable.
