Description

Technical Field

[0001] The utility model relates to the technical field of structural member welding, and particularly relates to a welding device for thin-walled structural members. Background Technique

[0002] When installing and producing aviation thin-walled structural members, a welding device is required to stably connect the thin walls. Welding refers to a connection method that makes two separated solid objects generate an atomic (molecular) bonding force through an appropriate physical and chemical process and connect them into one body. The two objects to be connected can be various metals, non-metals of the same or different types, or a metal and a non-metal. Since the connection of metals has great practical significance in modern industry and has developed into an advanced manufacturing technology for permanently connecting materials and enabling the welded joint to have a given function.

[0003] After retrieval, the Chinese patent with the publication number CN214024316U discloses a welding device for aviation thin-walled structural members, including a welding table, a control panel, a power cord, a sliding mechanism, a clamping mechanism, and a supporting mechanism. The control panel is arranged at the upper left end of the welding table, the power cord is arranged at the rear end of the control panel, the sliding mechanism is arranged at the upper right end of the welding table, the clamping mechanism is arranged at the upper left end of the welding table, and the supporting mechanism is arranged in the middle of the right end of the clamping mechanism.

[0004] The above existing technical solutions have the following deficiencies: they do not have the function of preheating the structural members before welding. For structural members with poor weldability, large joint restraint, and welded with ordinary non-low hydrogen welding materials, preheating before welding should be carried out. Also, for some structural members made of materials with high thermal conductivity, preheating should be carried out. Otherwise, it will lead to a reduction in the quality and performance of the welded joint, resulting in cold cracks and deformation, and harmful fumes will be generated during welding, polluting the working environment.

[0023] As Figure 1 shown, a welding device for thin-walled structural parts includes a machine body 100. A frame 110 is fixedly connected to the upper side wall of the machine body 100. Two guide rods 120 are fixedly connected between the inner walls on both sides of the frame 110. A moving seat 130 is slidably arranged between the two guide rods 120. A motor 140 is installed on the outer wall of one side of the frame 110. The output shaft end of the motor 140 extends into the frame 110 and is fixedly connected to a screw rod 150. The other end of the screw rod 150 is threadedly passed through the moving seat 130 and is rotatably connected to the inner wall of the other side of the frame 110. A positioning seat 160 is fixedly connected to the upper side wall of the moving seat 130. A controller 170 is installed on one side wall of the machine body 100. A welding robot 180 is installed on the upper side wall of the machine body 100 and behind the frame 110. A positioning assembly 400 is arranged on the positioning seat 160. An electromagnetic heating assembly 200 is also arranged in the frame 110. A purification assembly 300 is also arranged on the machine body 100. The guide rods 120 can guide the moving seat 130 to prevent it from rotating along with the screw rod 150. The output shaft of the motor 140 can drive the screw rod 150 to rotate. When the screw rod 150 rotates, it can make the moving seat 130 threadedly connected thereto drive the positioning seat 160 to move, so as to achieve the purpose of conveying the structural parts.

[0024] Specifically, as Figure 2As shown in the figure, a welding device for thin-walled structural parts, the electromagnetic heating component 200 includes a housing 210, an electromagnetic coil 220, a heat preservation layer 230 and a shielding layer 240. A housing 210 is fixedly connected between the inner walls on the front and rear sides of the frame body 110. An electromagnetic coil 220 is arranged inside the housing 210. A heat preservation layer 230 is arranged on the inner side of the inner circumferential wall of the housing 210 and a shielding layer 240 is arranged on the inner side of the outer circumferential wall. After the electromagnetic coil 220 is started, it can perform electromagnetic heating on the structural parts, so that the structural parts can be preheated before welding, and the heating speed is fast, effectively improving the quality and performance of the welded joints, avoiding the occurrence of cold cracks and deformation. The shielding layer 240 can prevent the electromagnetic coil 220 from affecting other electronic components during operation.

[0025] Specifically, as Figure 1 and Figure 3 As shown in the figure, a welding device for thin-walled structural parts, the purification component 300 includes a vertical rod 310, an air suction hood 320, a purification box 330, a fan 340, an air duct 350 and a purification filter element 360. A vertical rod 310 is fixedly connected to the upper side wall of the machine body 100 and in front of the frame body 110. The other end of the vertical rod 310 is fixedly connected to an air suction hood 320. A purification box 330 and a fan 340 are fixedly connected to the front side wall of the machine body 100. The purification box 330 is communicated with the air inlet end of the fan 340. The purification box 330 is communicated with the air suction hood 320 through an air duct 350 arranged therebetween. A purification filter element 360 is arranged inside the purification box 330. Under the action of the fan 340, the smoke generated during the welding process will be sucked into the air suction hood 320, and then enter the purification box 330 through the air duct 350. The purification filter element 360 adsorbs and purifies the smoke, and the purified air is discharged to the outside through the fan 340, preventing the welding smoke from polluting the working environment and protecting the health of workers.

[0026] Specifically, as Figure 4 As shown in the figure, a welding device for thin-walled structural parts, the positioning component 400 includes a groove 410, a placing block 420, a slider 430, a bidirectional screw 440, a knob 450 and a clamping block 460. A groove 410 is formed on the upper side wall of the positioning seat 160. A placing block 420 is fixedly connected to the middle of the groove 410. Two symmetrically distributed sliders 430 are slidably arranged inside the groove 410. A bidirectional screw 440 is rotatably arranged on the front side wall of the groove 410. The bidirectional screw 440 passes through the two sliders 430 and the placing block 420 and extends to the outside of the positioning seat 160 and is fixedly connected to a knob 450. The slider 430 is threadedly sleeved on the bidirectional screw 440. A clamping block 460 is fixedly connected to the upper side wall of the slider 430. Rotating the knob 450 can drive the bidirectional screw 440 to rotate. When the bidirectional screw 440 rotates, the two sliders 430 can drive the clamping blocks 460 to approach each other, and the two clamping blocks 460 will clamp and fix the structural parts.

[0027] Specifically, as Figure 3 shown, in a welding device for thin-walled structural parts, guiding grooves 331 are formed on the inner walls of the front and rear sides of the purification box 330. Slide rails 361 that are slidably engaged with the guiding grooves 331 are fixedly connected to the front and rear side walls of the purification filter element 360. A magnet 332 is embedded on one inner wall of the purification box 330, and an iron block that cooperates with the magnet 332 is embedded on one side wall of the purification filter element 360. When it is necessary to replace the purification filter element 360, the purification filter element 360 is pulled outwards. After overcoming the suction force of the magnet 332, the purification filter element 360 can be pulled out of the purification box 330. When installing a new purification filter element 360, the purification filter element 360 is inserted into the purification box 330, so that the slide rail 361 slides into the guiding groove 331. After the magnet 332 attracts the iron block on the purification filter element 360, the fixation of the purification filter element 360 can be completed. The disassembly and assembly are convenient and more practical.

[0028] Specifically, as Figure 4 shown, in a welding device for thin-walled structural parts, a patch type temperature sensor 421 is installed on the upper side wall of the placing block 420, which can monitor the temperature of the structural parts in real time.

[0029] In the specific implementation of the present utility model, the structural member is placed on the placing block 420, and then the knob 450 is rotated to drive the bidirectional screw 440 to rotate. When the bidirectional screw 440 rotates, the two sliders 430 can drive the clamping blocks 460 to approach each other, and the two clamping blocks 460 will clamp and fix the structural member. Then, the motor 140 is started through the controller 170. The output shaft of the motor 140 can drive the screw 150 to rotate. When the screw 150 rotates, the moving seat 130 can drive the positioning seat 160 to move. When the positioning seat 160 moves into the housing 210, the motor 140 stops working, and the controller 170 controls the electromagnetic coil 220 to start, performing electromagnetic heating on the structural member, enabling the structural member to be preheated before welding. Moreover, the heating speed is fast, effectively improving the quality and performance of the welded joint, avoiding the occurrence of cold cracks and deformation. The shielding layer 240 can prevent the electromagnetic coil 220 from affecting other electronic components during operation. The patch-type temperature sensor 421 can monitor the temperature of the structural member in real time. When the temperature reaches the preset value, the controller 170 controls the electromagnetic coil 220 to stop working and starts the motor 140. After transmission, the positioning seat 160 continues to move. When it moves below the welding robot 180, the welding robot 180 welds the structural member. This is the prior art and will not be elaborated here. Under the action of the fan 340, the smoke generated during welding will be sucked into the suction hood 320 and then enter the purification box 330 through the air duct 350. The purification filter element 360 adsorbs and purifies the smoke. The purified air is discharged to the outside through the fan 340, preventing the welding smoke from polluting the working environment and ensuring the physical health of workers. When it is necessary to replace the purification filter element 360, the purification filter element 360 is pulled outwards. After overcoming the suction force of the magnet 332, the purification filter element 360 can be pulled out of the purification box 330. When installing a new purification filter element 360, the purification filter element 360 is inserted into the purification box 330, so that the slide rail 361 slides into the guide groove 331. After the magnet 332 attracts the iron block on the purification filter element 360, the fixation of the purification filter element 360 is completed. The disassembly and assembly are convenient and more practical.
