Description

Technical Field

[0001] The present invention relates to the technical field of flame tube assembly welding, and in particular to flame tube intelligent assembly welding equipment and an assembly welding method thereof. Background Art

[0002] The flame tube is a thin-walled metal cylinder that controls combustion, mixing, and cooling. It prevents high-temperature combustion products from affecting the engine casing and shaft. Most cylinders are formed by split stamping or spinning, resulting in a large difference in the size of the two ends of the cylinder. This makes it difficult to achieve the ideal gap required for resistance welding during assembly and welding, resulting in severe spatter, which affects weld strength. Furthermore, it is difficult to ensure the coaxiality of each section after the overall assembly is completed.

[0003] A search revealed a Chinese patent application for a welding device for a flame tube assembly. The Chinese invention patent, publication number CN118218832A, provides a concentric clamping structure that automatically positions the first and second cylindrical members concentrically, preventing weld offset during welding. Furthermore, a tension spring is used to support and clamp the inner walls of the first and second cylindrical members, preventing damage to the weldment caused by excessive clamping, effectively improving the weld yield rate.

[0004] However, the above device still has some shortcomings when in use. When assembling the flame tube, it is necessary to rely on manual positioning first, the overall assembly efficiency is low, and it is not suitable for large-scale assembly and welding of flame tubes. In addition, it is difficult to adjust the angle of the clamped flame tube components during the welding process, which affects the welding effect. Summary of the Invention

[0016] The present invention also provides a flame tube intelligent assembly welding method, comprising the following steps:

[0017] Step 1: Place the flame tube components that need to be assembled and welded on the top of the incoming material tray, and manually load them into the accompanying positioning fixture set on the top of the chain conveyor, so as to convey the flame tube components that need to be assembled to the grinding mechanism;

[0018] Step 2. After the flame tube component enters the interior of the sheet metal shell one, the grinding robot in the grinding component starts to work, and clamps the flame tube component from the accompanying positioning fixture to the side of the force control device two. At this time, the grinding spindle starts to work and grinds the inner and outer sides of the outer end of the flame tube component clamped on the side of the force control device two. After the grinding is completed, the servo slide one drives the power control device one to move, and the chuck fixture one set on the side of the force control device one grabs the flame tube component from the side of the force control device two, and grinds the inner and outer sides of the other end of the flame tube component through the grinding robot and the grinding spindle. After the grinding is completed, the grinding robot grabs the flame tube component from the side of the force control device one, and puts it into the accompanying positioning fixture at the top of another chain conveyor, and drives the polished flame tube component into the positioning and assembly mechanism through the chain conveyor;

[0019] Step three, after the flame tube component that has been polished is transported to the interior of the positioning and assembly mechanism, the flame tube component is loaded onto the side of the servo turntable 1 in the correction and assembly component through the work of the loading component, and the flame tube component is clamped by the chuck fixture 2. The servo turntable 1 drives the chuck fixture 2 and the flame tube component clamped inside it to rotate. During the rotation of the flame tube component, the correction component will detect the corresponding features of the flame tube and then locate the assembly angle of the product. After correction, the flame tube component is loaded onto the outer wall of the inner expansion rod through the cooperation between the servo slide 2 and the servo turntable 1, and the flame tube component is clamped by the clamping claw. After clamping, the inner expansion rod will open the assembly end of the flame tube component, and then repeat the above-mentioned loading and position correction process of the flame tube component. The second flame tube component is assembled to the side of the first flame tube component, the inner expansion rod is loosened, and the assembly of the two flame tube components is completed. The servo slide 2 drives the servo turntable 1 to push the product to the corresponding depth, and the product is welded by the laser welding gun. The clamp clamps the welded product and pushes the product to the corresponding position through the servo turntable 1. The inner expansion rod opens the assembly end, and the above process is repeated in sequence. The third flame tube component, the fourth flame tube component, and the seventh flame tube component are all assembled. The loading robot clamps the assembled and preliminarily welded flame tube and places it on the turntable. The unloading robot in the unloading and roll welding components clamps the flame tube through the chuck fixture 4 and transports it to the front end of the roll welding machine, and the flame tube is roll welded by the roll welding machine.

[0020] Step 4: After the seam welding is completed, the flame tube is transported to the top of the unloading conveyor by the unloading robot, and then transported to the manual inspection table by the unloading conveyor. After the inspection of the flame tube is completed, the assembled flame tube can be packed.

[0021] Beneficial effects of the present invention:

[0022] Through the work of the grinding mechanism, the flame tube components can be ground before being assembled and welded, and the ground flame tube components can be transported to the accompanying positioning fixture through the grinding robot, so as to facilitate the subsequent assembly and welding of the flame tube components;

[0023] Through the work of the positioning and assembly mechanism, the flame tube components that have been polished can be loaded into the correction and assembly components through the loading component, and the corresponding features of the components can be detected to locate the product angle, and multiple flame tube components can be preliminarily assembled to ensure that the assembled flame tubes are on the same axis. The assembled flame tubes can then be seam welded, thereby quickly completing the assembly and welding of the flame tubes.

[0024] Through the operation of the above-mentioned mechanism, the flame tube can be polished before assembly to facilitate subsequent welding operations. After polishing, multiple flame tube components can be assembled together, and it is ensured that the assembled multiple flame tube components are on the same axis, thereby improving the yield after welding. The entire set of equipment is automatically controlled and operates on an assembly line, which can improve the assembly efficiency of the flame tube and is suitable for large-scale operations.
