Description

Technical Field

[0001] This utility model relates to the fields of mechanical manufacturing and metal processing, and in particular to a welding device for an operating lever. Background Technology

[0002] In the field of mechanical manufacturing and metal processing, the welding quality of the control lever, as a transmission component, directly affects the reliability and safety of equipment operation. Traditional control lever welding devices usually consist of a clamping assembly and a welding assembly. After the workpiece is fixed by the clamping assembly, the welding assembly completes the fusion connection. However, in the welding process of special materials such as aluminum alloys or galvanized parts, the fluoride flux in the welding material will decompose at high temperature to produce volatile gases such as hydrogen fluoride (HF).

[0003] When galvanized parts are welded, the zinc layer vaporizes upon heating, forming zinc vapor. These gases are toxic, and if they are directly released into the work environment, they will affect the health of the operators. Workers who are exposed to these gases for a long time may develop occupational metal fume fever and other health problems, causing inconvenience to actual use.

[0004] Therefore, it is necessary to provide a new welding device for the operating rod to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 4 ,in, Figure 1 A schematic diagram of the overall structure of the welding device for the operating rod provided by this utility model; Figure 2 This is a schematic diagram of the fastener groove structure; Figure 3 This is a structural diagram of the component being installed; Figure 4 This is a cross-sectional structural diagram of the welding device for the operating rod provided by this utility model.

[0025] In some embodiments, such as Figures 1 to 4 As shown, it includes a clamping assembly and a welding assembly located on one side of the clamping assembly. A suction assembly is fixed to the top of the clamping assembly. A filter pipe 5 is installed inside the suction assembly. A filter assembly is installed at one end of the filter pipe 5. The filter assembly includes a coarse filter layer 52, an odor adsorption layer 53 and a fine filter layer 54, which are fixed to the inner wall of the filter pipe 5 from the outside to the inside. A groove 512 is also provided on the inner wall of the filter pipe 5.

[0026] The coarse filter layer 52 is used to initially intercept large particulate impurities and is preferably a metal mesh or stainless steel filter.

[0027] Odor adsorption layer 53 is used to adsorb harmful gases and odors such as fluoride and zinc vapor. It is preferably a honeycomb-shaped activated carbon layer that captures fluoride, zinc vapor, volatile organic compounds (VOCs) in the gas through physical adsorption.

[0028] Fine filter layer 54 is used to filter small particles, preferably glass fiber or PTFE composite membrane, model PTFE-70, to intercept tiny particles that have not been filtered by the first two layers, such as PM2.5, residual metal vapor condensates, etc.

[0029] Specifically, the filtration components of this device adopt a three-stage progressive design: coarse filtration layer 52 → odor adsorption layer 53 → fine filtration layer 54, forming a gradient purification barrier. The coarse filtration layer 53 prioritizes intercepting large particulate impurities to prevent clogging of subsequent filtration layers. The odor adsorption layer specifically adsorbs hydrogen fluoride gas, zinc vapor, and volatile organic compounds. The fine filtration layer captures fine particles. To a certain extent, it can adsorb and purify toxic gases generated during the welding of aluminum alloys or galvanized parts, reducing the concentration of harmful substances in the air in the work area, reducing the risk of occupational metal fume fever for workers, and providing a healthier working environment for workers.

[0030] Furthermore, the filter pipe 5 of this device adopts a plug-in detachable connection design, which makes it easy to remove the filter pipe 5 for maintenance periodically. In addition, by providing a buckle groove 512 on the inner side wall of the filter pipe 5, it is easy for the staff to remove the filter pipe 5 for subsequent maintenance.

[0031] In some embodiments, reference is made to Figures 1 to 4 As shown, the clamping assembly includes a worktable 1 and a clamping component. The clamping component and the suction assembly are both fixed to the top of the worktable 1. The suction assembly is located on one side of the clamping component, and the welding assembly is located on one side of the worktable 1.

[0032] The suction assembly includes a housing 4, which is fixed to the top of the workbench 1. A slot 41 is provided on one side of the housing 4. One end of the filter pipe 5 is inserted into the slot 41. Multiple limiting grooves 42 are provided on the inner side wall of the slot 41. A guide plate 44 and a fan 46 are fixed on the inner side wall of the housing 4. The fan 46 is located on one side of the guide plate 44. An arc-shaped end 45 is formed at each corner inside the housing 4. A ventilation hole 47 is also provided on the side of the housing 4 near the fan 46.

[0033] Multiple limiting blocks 51 are fixed on the outside of the filter pipe 5. The filter pipe 5 is inserted into multiple limiting grooves 42 through the multiple limiting blocks 51. A filter screen plate 43 is also fixed on the side of the filter pipe 5 away from the limiting blocks 51. The filter screen plate 43 is located on the side close to the fine filter layer 54. Multiple insertion holes 511 are also opened on the outside of the multiple limiting blocks 51.

[0034] Multiple mounting components are fixed on the outside of the housing 4, and one end of each mounting component is inserted into a multiple socket 511.

[0035] Multiple mounting components include mounting brackets 6, which are fixed to the side of the housing 4 near the limiting groove 42. The inner side wall of the mounting bracket 6 is provided with a sliding groove 61. The top wall of the mounting bracket 6 is provided with a telescopic insertion rod 62. One end of the insertion rod 62 passes through the top of the mounting bracket 6 and is fixed with a limiting plate 621. A rubber ring 622 is fixed at the bottom of the insertion rod 62. Two sliding plates 623 are fixed in the middle of the insertion rod 62. The two sliding plates 623 are located between the rubber ring 622 and the top wall of the mounting bracket 6. The ends of the two sliding plates 623 away from the insertion rod 62 slide on the inner side wall of the sliding groove 61. A spring 624 is also provided between the two sliding plates 623 and the top wall of the mounting bracket 6. The two ends of the two springs 624 are fixedly connected to the top wall of the mounting bracket 6 and the top of the two sliding plates 623, respectively.

[0036] Specifically, during the welding process, the fan 46 starts, creating a negative pressure inside the housing 4. Harmful gases such as hydrogen fluoride (HF) and zinc vapor generated during welding are drawn into the housing 4 through the air inlet on the surface of the filter pipe 5. The guide plate 44 guides the gas to flow along a preset path, and the arc-shaped end 45 reduces airflow dead angles and improves gas passage efficiency. During the intake process, the gas first passes through the coarse filter layer 52 inside the filter pipe 5 to intercept large particulate impurities. Then it enters the odor adsorption layer 53 to adsorb HF gas and volatile organic compounds. Finally, it passes through the fine filter layer 54 and the filter screen 43 to capture small particulate matter. When the filter components need to be replaced, hold the limiting plate 621 and pull it upward to compress the spring 624 of the insertion rod 62 and disengage it from the insertion hole 511. At the same time, hold the latch 512 to pull out the filter pipe 5. During installation, the operation is reversed, and the spring 624 returns to its elastic deformation, driving the insertion rod 62 to lock automatically.

[0037] Furthermore, when the insertion rod 62 is driven by the spring 624 to quickly insert into the insertion hole 511 of the filter pipe 5, the rubber ring 622 is located between the bottom of the insertion rod 62 and the bottom wall of the mounting bracket 6. It absorbs the impact force through elastic deformation, avoiding wear or deformation caused by direct collision of metal parts. Moreover, the rubber ring 622 has a certain deformation capacity, so that when the insertion rod 62 is inserted, the outer side of the rubber ring 622 is squeezed against the insertion hole 511, making the connection more secure.

[0038] In addition, the cushioning effect of the rubber ring 622 can reduce the impact noise when the spring 624 rebounds.

[0039] In some embodiments, reference is made to Figure 1 as well as Figure 2 As shown, the welding assembly includes a robotic arm 2, with a mounting base 21 fixed to the output end of the robotic arm 2, and a welding torch 22 fixed to the bottom of the mounting base 21.

[0040] An operating table 11 is also fixed to one side of the workbench 1, and a display screen is provided on the surface of the operating table 11.

[0041] The clamping components include a three-jaw chuck 3, which is mounted on top of the worktable 1.

[0042] Among them, welding torch 22 is used for welding operating rods;

[0043] Among them, the three-jaw chuck 3 is used to clamp the operating lever. The preferred model is IS768-85605, which is existing technology and will not be described in detail here.

[0044] Specifically, the operator controls the robotic arm 20 to drive the welding torch 22 to move along a preset trajectory via the display screen of the control panel 11. This is common knowledge and will not be described in detail here.

[0045] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
