DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The device is mainly used for end welding of wall-mounted steel radiators. The special-shaped radiator a is shown in Figure 1. Both ends are approximately square heads and are connected by two hollow tubes. Therefore, when the steel pipe and the square head of the special-shaped radiator a are welded, due to the narrow space in the middle, it is difficult for traditional welding equipment to perform welding operations around the circle.

Embodiment 1, as shown in FIG2, a welding rod comprises a welding arm 1251 and a welding head 1252, the welding arm 1251 and the welding head 1252 are fixed to form a welding rod 125, an angle is set between the welding arm 1251 and the welding head 1252, the angle is ≥90°, this welding rod 125 is different from a traditional straight rod, when a traditional welding rod is used to weld cylindrical or arc-shaped objects, the tail end has a large range of movement and needs to rotate in an approximately circular shape, so during CNC operation, precise CNC equipment is required to operate, which is costly. When the welding rod 125 is used in conjunction with the following equipment, it can significantly reduce the demand for CNC and reduce costs.

Embodiment 2, as shown in FIG3 and FIG4, an end welder includes the above-mentioned welding rod 125, and also includes a linear slide 13, a linear slide 2 14 and a connecting arm 16, a welding part 12 is installed at one end of the connecting arm 16, the welding part 12 includes a frame box 121, the welding rod 125 is arranged on one side of the frame box 121, the frame box 121 is provided with a driving part, the welding part 12 controls the welding rod 125 to move along the surface of the workpiece to be processed in an arc trajectory for welding by the driving part, and the welding part 12 is moved horizontally and lifted and lowered by the linear slide 13 and the linear slide 2 14 to assist in the welding action.

As shown in Figure 3, in order to ensure the smooth implementation of this embodiment, it is necessary to understand that the slide seat of the linear slide 2 14 slides on the linear slide 13, the linear slide 2 14 is perpendicular to the linear slide 13 and the linear slide 2 14 is perpendicular to the ground, the connecting arm 16 is rotatably installed on the slider of the linear slide 2 14, and the other side of the slider is equipped with a driving source 15 for controlling the rotation of the connecting arm 16. An arc-shaped notch 1212 is provided at the bottom of the frame box 121, and the arc-shaped notch 1212 at the bottom of the frame box 121 spans the steel pipe of the special-shaped radiator a, so when the welded part 12 needs to be reversed and rotated 180° for welding again, the welded part 12 needs to be lifted and lowered first and then rotated, and the welded part 12 can be controlled to rotate by the driving source 15.

As shown in FIG. 4 , in order to ensure the smooth implementation of this embodiment, it should be understood that the frame box 121 is hollow inside, and a threaded rod 1210 is rotatably connected between the inner walls at both ends of the frame box 121. A slider 129 screwed to the surface of the threaded rod 1210 is also provided between the inner walls on both sides of the frame box 121. A telescopic rod 128 is fixed to the surface of the slider 129. The top of the telescopic rod 128 is connected to the welding rod 125 through a connecting rod. A screw rod 128 is installed outside the frame box 121 for driving the threaded rod 1210. The motor 1211 is used, the surface of the frame box 121 is provided with an arc groove, the connecting rod slides on the inner wall of the arc groove, the connecting rod is connected to the end of the welding rod 125 away from the welding head 1252, the surface of the frame box 121 is fixed with a stopper 127, the stopper 127 is located at a position where the welding head 1252 is perpendicular to the horizontal plane, the frame box 121 is rotatably connected to a row of rollers 122 near the top position, the rollers 122 slide with a slider 123, the frame box 121 is provided with a slide groove near the rollers 122, and the slider 123 is provided with a slide groove. A spring 124 is fixed on one end of the welding rod 125 through the slide slot, and the other end of the spring 124 is installed on the end of the welding rod 125 away from the welding head 1252. Through the arrangement of this structure, the welding rod 125 can be controlled to always stick to the surface of the special-shaped heat sink a for welding. When the motor 1211 controls the threaded rod 1210 to rotate, the threaded rod 1210 acts on the slider 129, so that the slider 129 moves horizontally under the limit. Under this guidance, the welding rod 125 moves horizontally. Under the guidance of the arc groove, welding is performed along the surface of the radiator tube. Normally, the curvature of the arc groove is consistent with the curvature of the surface of the radiator tube, or the curvature of the arc groove can be relatively smooth. Since the end of the welding rod 125 is pulled by the spring 124, the welding head 1252 of the welding rod 125 always tends to be downward under the action of the lever, and welding can also be performed along the surface of the radiator tube during the movement. Under the obstruction of the block 127, the welding rod 125 can be prevented from leaving the surface of the radiator tube.

As shown in Figure 4, in order to ensure the smooth implementation of this embodiment, it is necessary to understand that a guide tube 126 for pulling the welding wire is fixed on the surface of the welding rod 125 through a short rod, and one end of the guide tube 126 is aligned with the welding head 1252 of the welding rod 125. The guide tube 126 can always keep the welding wire aligned with the welding point, thereby avoiding the deviation of the welding wire guidance during the mobile welding process.

As shown in Figure 5, Example 3 is an end welding device for welding special-shaped heat sinks, which uses an end welder and a welding rod, including a welding machine 1 and two bases 2. Two groups of end welders are provided, and a linear slide 13 of each group of end welders is installed on the corresponding base 2. A welding area is formed between the two bases 2. A clamping mechanism is provided on the side of each base 2 facing the welding area. Two groups of end welders are provided to simultaneously weld the two ends of the special-shaped heat sink a, thereby improving welding efficiency. A welding slag collection tank 5 is provided on the welding machine 1 to collect welding slag generated during the welding process. During use, the special-shaped heat sink a is clamped and fixed by the clamping mechanisms at both ends to facilitate the welding action of the end welder. A transversely movable protective door 4 is installed on the two bases 2. During welding, the protective door 4 moves transversely to block the welding area to protect the operator and provide a safer welding environment. Two winding rollers 3 are also installed on the welding machine 1 to output welding wire and provide stable welding wire output through the guide tube 126.

As shown in Figure 6, in order to ensure the smooth implementation of this embodiment, it is necessary to understand that the clamping mechanism includes a back plate 6 rotating on one side of the base 2, and a carrier plate 10 for placing the workpiece to be processed is fixed on the side of the back plate 6 facing the welding area, and clamping arms 11 located on both sides of the carrier plate 10 are also rotated on one side of the back plate 6, and a hanging plate 7 located above the carrier plate 10 is fixed on one side of the back plate 6, and a pressing plate 8 is arranged between the hanging plate 7 and the carrier plate 10, and a screw 9 screwed to the hanging plate 7 is rotated on the top of the pressing plate 8. During use of this embodiment, the two ends of the special-shaped heat sink a are respectively placed on the carrier plates 10 at both ends, and then clamped by the clamping arms 11, the clamping arms 11 are CNC-controlled rotated by electric drive or controlled to rotate by a switch, and then the screw 9 on the top is rotated to make the pressing plate 8 descend and press on the two ends of the special-shaped heat sink a to clamp the special-shaped heat sink a. During the clamping process, the back plate 6 can rotate.

Therefore, during the use of the device, the special-shaped radiator a is first clamped by the clamping mechanism to keep the special-shaped radiator a stable, and then welded by the welding device. During the welding process, the welding piece 12 welds the connection between the end of the special-shaped radiator a and the steel pipe each time and welds a quarter. If the cross-section of the steel pipe is circular, a quarter of the circle is welded at a time. The welding of a single steel pipe and the special-shaped radiator a needs to be completed in four welding operations, which can perform efficient welding operations on the special-shaped radiator a of the wall-mounted steel radiator.
