Description

Technical Field

[0001] The utility model relates to the technical field of welding processing, in particular to an auxiliary tool for positioning welding of thin-walled steel components. Background Art

[0002] Welding is a process that combines two or more metal parts by heating them to melting point and then joining them together to form a strong connection, usually using a welding material (called solder) to fill the joint to ensure the strength and stability of the connection. Welding is commonly used in manufacturing, construction, and repair.

[0003] Currently, when welding two thin-walled steel components together, they first need to be fixed separately. After welding one side, they need to be removed first, turned over, and then re-fixed and welded on the other side. However, repeated fixing and removal of components will increase production time, especially in the case of batch welding, which will lead to low processing efficiency. In addition, the welding process will be accompanied by welding smoke, which often carries metal oxides, organic gases and carcinogens. If workers are exposed to welding smoke for a long time, it may cause serious health effects, including respiratory diseases, nervous system problems and even cancer. Utility Model Content

[0004] The utility model aims to provide an auxiliary tool for positioning welding of thin-walled steel components, which is convenient for flipping and welding components and reduces the harm of welding smoke to workers.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A thin-walled steel member counter-welding auxiliary tooling includes a base plate, side plates are installed on both sides of the upper surface of the base plate, driven gears are rotatably installed on the opposite surfaces of the two side plates, placement plates are installed on the opposite surfaces of the two driven gears, and clamps are installed inside the placement plates through a clamping mechanism. A flipping mechanism that can simultaneously drive the two driven gears to rotate is provided on the upper side of the base plate. An L-shaped mounting plate is installed on the upper surface of the base plate, an air suction hood is installed on the lower surface of the horizontal plate of the L-shaped mounting plate, and the air suction hood corresponds to the two placement plates, and a purification box is installed on the upper surface of the horizontal plate of the L-shaped mounting plate, and a dustproof net and an activated carbon filter are respectively inserted inside the purification box. A first connecting pipe is connected to the outer surface of one side of the purification box, and the end of the first connecting pipe is connected to the air suction hood, a fan is installed on the outer surface of the L-shaped mounting plate, and the end of the air suction end of the fan is connected to the second connecting pipe, and the end of the second connecting pipe is connected to the outer surface of the other side of the purification box.

[0007] It can be seen that by setting up the clamping mechanism, the thin-walled steel components can be fixed. After welding one side, the two driven gears can be driven to rotate by the flipping mechanism, thereby achieving the purpose of flipping the thin-walled steel components. There is no need to perform the tedious and time-consuming operations of repeatedly fixing and removing the components, thereby greatly improving the processing efficiency in the case of batch welding, and the smoke generated by welding can be discharged after being filtered by the dustproof net and purified by the activated carbon filter, thereby greatly reducing the harm of welding smoke to the workers' bodies.

[0008] Furthermore, the clamping mechanism includes a first screw rod that passes through the interior of the placement plate and is threadedly connected thereto, and one end of the first screw rod is rotatably connected to the clamping plate, and a first knob is installed on the other end of the first screw rod. First limiting rods are connected to both sides of the outer surface of the clamping plate, and the end of the first limiting rod passes through the outside of the placement plate.

[0009] When the thin-walled steel component is placed in the placement plate, the first knob can be turned to drive the first screw to rotate. Since the first limiting rod limits the clamping plate, the clamping plate can be steadily pressed against the surface of the thin-walled steel component to achieve the purpose of fixing it.

[0010] Furthermore, the flipping mechanism includes a connecting shaft rotatably connected between the two side plates, two driving gears are sleeved on the outer surface of the connecting shaft, and the two driving gears are respectively meshed with two driven gears, one end of the connecting shaft passes through the outer side of the side plate and is installed with a worm gear, two side blocks are installed on the outer surface of the side plate, a worm is rotatably connected between the two side blocks, and the worm is meshed with the worm gear, and a handle is installed on the end of the worm.

[0011] When it is necessary to turn over the component, the handle can be rotated, and the handle drives the worm to rotate. Since the worm and the worm wheel are meshed with each other, the connecting shaft can be driven to rotate, and the two driving gears on its surface can be driven to rotate. Since the driving gear and the driven gear are meshed with each other, the two driven gears can be driven to rotate at the same time, and the purpose of driving the component to be turned over can be achieved. Since the worm and the worm wheel have very good self-locking properties, the stability of the component during welding can be guaranteed, and the welding quality can be guaranteed.

[0012] Furthermore, handles are installed on the upper ends of the dustproof net and the activated carbon filter.

[0013] The handle makes it easy to pull out the dust screen and activated carbon filter, and clean and replace them.

[0014] Furthermore, U-shaped rods are rotatably installed on both side surfaces of the cross plate of the L-shaped mounting plate, a second screw rod is passed through the inside of the U-shaped rod and is threadedly connected, a pressure plate is rotatably connected to the lower end of the second screw rod, a second knob is installed on the upper end of the second screw rod, two second limiting rods are connected to the outer surface of the pressure plate, and the ends of the second limiting rods pass through the outside of the U-shaped rod.

[0015] When the dust screen and activated carbon filter need to be pulled out, the second knob can be turned first to drive the second screw to rotate. Since the second limit rod limits the pressure plate, it can drive the pressure plate to move vertically upward. Then the U-shaped rod is flipped to the side of the purification box, so that the dust screen and activated carbon filter can be pulled out for cleaning and replacement. After the dust screen and activated carbon filter are reinserted into the purification box, the U-shaped rod can be flipped to the top of the purification box, and then the second knob can be turned in the opposite direction to drive the pressure plate to descend vertically and press it against the surface of the two handles, so that the dust screen and activated carbon filter can be quickly fixed to prevent them from loosening and causing air leakage.

[0016] Furthermore, the outer surface of the clamping plate and the side wall of the placement plate facing the clamping plate are both provided with rubber pads, and the surface of the rubber pads is provided with anti-slip grooves.

[0017] By providing rubber pads and anti-slip grooves, the protection effect on thin-walled steel components can be improved to avoid damage thereto, and the friction force on the surface thereof can be increased to further improve the fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a thin-walled steel member counter-welding auxiliary tooling includes a bottom plate 100, side plates 101 are installed on both sides of the upper surface of the bottom plate 100, driven gears 102 are rotatably installed on the opposite surfaces of the two side plates 101, placement plates 103 are installed on the opposite surfaces of the two driven gears 102, and clamping plates 112 are installed inside the placement plates 103 through a clamping mechanism 200. A flipping mechanism 300 capable of driving the two driven gears 102 to rotate at the same time is arranged on the upper side of the bottom plate 100. An L-shaped mounting plate 104 is installed on the upper surface of the bottom plate 100, a suction hood 105 is installed on the lower surface of the horizontal plate of the L-shaped mounting plate 104, and the suction hood 105 corresponds to the two placement plates 103, and a purification box 106 is installed on the upper surface of the horizontal plate of the L-shaped mounting plate 104, and a dustproof net 107 and an activated carbon filter 108 are respectively inserted inside the purification box 106. A first connecting pipe 109 is connected to the outer surface of one side of the purification box 106, and the end of the first connecting pipe 109 is connected to the suction hood 105. A fan 110 is installed on the outer surface of the L-shaped mounting plate 104. The end of the suction end of the fan 110 is connected to the second connecting pipe 111, and the end of the second connecting pipe 111 is connected to the outer surface of the other side of the purification box 106.

[0026] When in use, first place two thin-walled steel components in two placement plates 103 respectively, and adjust the distance between the two, then drive the clamping plate 112 to press on the surface of the component through the clamping mechanism 200 to fix it, and then the worker can use the welding gun to perform welding operations. When the welding of one side is completed, the flipping mechanism 300 can drive the two driven gears 102 to rotate at the same time, and the driven gear 102 drives the placement plate 103 to rotate, so as to achieve the purpose of flipping the component, and then weld the other side, which can greatly improve the welding efficiency. Efficiency; and during the welding process, the welding smoke floats upward, and the fan 110 is started. The suction force generated by the fan 110 acts on the suction hood 105. Under the interaction of the two, the welding smoke can be sucked from the suction hood 105 and enter the purification box 106. The welding smoke first passes through the dustproof net 107 to filter the impurity particles contained therein, and then the welding smoke passes through the activated carbon filter 108 to filter the harmful substances and odors contained therein. Finally, the purified welding smoke is discharged from the air outlet of the fan 110, thereby greatly reducing the harm of the welding smoke to the workers' bodies.

[0027] Specifically, the clamping mechanism 200 includes a first screw 201 that passes through the interior of the placement plate 103 and is threadedly connected thereto, and one end of the first screw 201 is rotatably connected to the clamp plate 112, and the other end of the first screw 201 is installed with a first knob 203. First limiting rods 202 are connected to both sides of the outer surface of the clamp plate 112, and the ends of the first limiting rods 202 pass through the outer side of the placement plate 103. When the thin-walled steel component is placed in the placement plate 103, the first knob 203 can be turned to drive the first screw 201 to rotate. Since the first limiting rod 202 limits the clamp plate 112, the clamp plate 112 can be smoothly pressed against the surface of the thin-walled steel component to achieve the purpose of fixing it.

[0028] Specifically, the flipping mechanism 300 includes a connecting shaft 301 rotatably connected between the two side plates 101, two driving gears 302 are sleeved on the outer surface of the connecting shaft 301, and the two driving gears 302 are respectively meshed with the two driven gears 102, one end of the connecting shaft 301 passes through the outer side of the side plate 101 and is installed with a worm wheel 303, two side blocks 304 are installed on the outer surface of the side plate 101, a worm 305 is rotatably connected between the two side blocks 304, and the worm 305 is meshed with the worm wheel 303, and a handle 303 is installed at the end of the worm 305. 6. When it is necessary to turn over the component, the handle 306 can be rotated, and the handle 306 drives the worm 305 to rotate. Since the worm 305 and the worm wheel 303 are meshed with each other, the connecting shaft 301 can be driven to rotate, and the two driving gears 302 on the surface thereof can be driven to rotate. Since the driving gear 302 and the driven gear 102 are meshed with each other, the two driven gears 102 can be driven to rotate at the same time, and the purpose of driving the component to be turned over can be achieved. Since the worm 305 and the worm wheel 303 have very good self-locking properties, the stability of the component during welding can be guaranteed, and the welding quality can be guaranteed.

[0029] Specifically, handles 400 are installed on the upper ends of the dustproof net 107 and the activated carbon filter 108. The handles 400 facilitate the dustproof net 107 and the activated carbon filter 108 to be pulled out, cleaned, and replaced.

[0030] Specifically, U-shaped rods 500 are rotatably installed on both sides of the horizontal plate of the L-shaped mounting plate 104, and a second screw rod 501 is penetrated and threadedly connected inside the U-shaped rod 500, and a pressure plate 502 is rotatably connected to the lower end of the second screw rod 501, and a second knob 503 is installed on the upper end of the second screw rod 501. Two second limiting rods 504 are connected to the outer surface of the pressure plate 502, and the ends of the second limiting rods 504 penetrate to the outside of the U-shaped rod 500. When the dust screen 107 and the activated carbon filter 108 need to be pulled outward, the second knob 503 can be turned first to drive the second screw 501 to rotate. The U-shaped rod 500 is then turned over to the side of the purification box 106, so that the dust net 107 and the activated carbon filter 108 can be pulled out for cleaning and replacement. After the dust net 107 and the activated carbon filter 108 are reinserted into the purification box 106, the U-shaped rod 500 can be turned over to the top of the purification box 106, and then the second knob 503 is turned in the opposite direction, thereby driving the pressure plate 502 to descend vertically and press against the surfaces of the two handles 400, so that the dust net 107 and the activated carbon filter 108 can be quickly fixed to prevent them from loosening and causing air leakage.

[0031] Specifically, the outer surface of the clamping plate 112 and the side wall of the placement plate 103 facing the clamping plate 112 are both provided with rubber pads, and the surface of the rubber pads is provided with anti-slip grooves.
