Description

Technical Field

[0001] The present invention relates to the technical field of drum welding, and particularly relates to a processing and welding device for a washing machine cleaning drum. Background Art

[0002] In actual drum manufacturing work, for example, a washing machine cleaning drum, its structure consists of a steel pipe and drum shafts at both ends, which are installed by welding. Subsequently, bristles are installed on the outer side of the steel pipe. The processing accuracy of the drum directly affects the subsequent drum rotation accuracy. Currently, the existing processing and welding devices for washing machine cleaning drums are not convenient for stably and coaxially clamping the steel pipe and the drum shafts at both ends. At the same time, there will be a gap between the steel pipe and the drum shafts. In the traditional welding method, it is not convenient to achieve internal smoke exhaust, and the external smoking method is likely to interfere with the operation of welding. At the same time, it is not convenient to quickly inspect the welding accuracy inside the drum. Also, it is not convenient to automatically control the straightness of the steel pipe of the drum before welding, which is likely to cause welding errors. The method of directly welding the drum shafts at both ends and then straightening them is likely to damage the welding seam by extruding and straightening with a straightening machine.

It is more convenient to inspect the inner side of the weld, improve the operation quality of the staff during welding. At the same time, this structure can be used multiple times. By rotating the handheld telescopic shaft, the swing rod is driven to swing rotationally inside the roller shaft. By cooperating with the axial scale, the data change can be observed, and when there is jamming, the staff can know the existence of a molten bulge inside through the touch feeling.

[0040] As Figures 2 to 5As shown, the welding support 1 further includes a roller steel pipe 103 placed in the V-shaped grooves on two support blocks 102; roller shafts 104 are sleeved at both ends of the roller steel pipe 103; the support blocks 102 are used to support the roller steel pipe 103 for workers to weld the roller shafts 104; through holes are drilled on the roller shafts 104; the precision control member 2 includes a positioning sleeve 201 located outside the roller steel pipe 103; a sleeve frame 2011 is fixedly installed on the positioning sleeve 201; the sleeve frame 2011 is fixedly installed on the welding mounting plate 101 by bolts; a circle of fixing pieces 202 is fixedly installed inside the positioning sleeve 201; a circle of electrical connection elastic pieces 203 is fixedly installed inside the positioning sleeve 201, and the end parts of the circle of electrical connection elastic pieces 203 are respectively attached to the end parts of the circle of fixing pieces 202; the inner sides of the circle of electrical connection elastic pieces 203 are respectively attached to the roller steel pipe 103; an insulating coating is provided on the side close to the roller steel pipe 103; arc-shaped pieces 204 are respectively fixedly installed on the sides of the circle of electrical connection elastic pieces 203; the circle of arc-shaped pieces 204 are respectively of arc-shaped structures; the installation limiting member 3 includes two electromagnets 301 respectively fixedly installed inside the two support blocks 102; the two electromagnets 301, the circle of electrical connection elastic pieces 203 and the circle of fixing pieces 202 are connected in series to a power source; limiting columns 302 are respectively slidably inserted on the two support blocks 102; the two limiting columns 302 are respectively aligned with the two electromagnets 301; the two electromagnets 301 are respectively used to magnetically attract the two limiting columns 302; reset springs 303 are respectively fixedly installed at the bottoms of the two limiting columns 302; the other ends of the two reset springs 303 are respectively connected to the two electromagnets 301;Two reset springs 303 are respectively located inside the two support blocks 102. By using the precision control part 2, it is possible to detect the straightness of the drum steel pipe 103 when installing and welding the drum steel pipe 103, which is convenient for the staff to directly understand whether the processing accuracy of the drum steel pipe 103 meets the standard. At the same time, by using the installation limit part 3, the limit control work can be realized, ensuring that only after the processing accuracy of the drum steel pipe 103 meets the standard can the column head limit part 4 be normally installed for the clamping and positioning work of the drum shaft 104, avoiding direct operation of welding by the staff. This structure is accurate and efficient in detecting the straightness of the drum steel pipe 103, can ensure the detection quality, and avoid inaccurate straightening of the drum steel pipe 103 in the early stage. If the drum shaft 104 is welded at both ends of the drum steel pipe 103 and then straightened by a straightening machine, the drum steel pipe 103 will bend. At this time, internal stress will be generated in the drum steel pipe 103. Coupled with the extrusion of the end by the straightening machine, cracks and other problems are likely to occur in the weld between the end of the drum steel pipe 103 and the drum shaft 104. This structure is simple and flexible to operate. By passing the drum steel pipe 103 through the loop contact elastic sheet 203 from one side of the arc-shaped piece 204, the arc-shaped piece 204 can facilitate the passing of the drum steel pipe 103 by using the arc structure to prevent jamming. Place the drum steel pipe 103 between the two support blocks 102. At this time, if the bending of the drum steel pipe 103 exceeds the standard, the drum steel pipe 103 will no longer be concentric with the positioning sleeve 201. The loop contact elastic sheet 203 still elastically adheres to the drum steel pipe 103, but due to non-concentricity, the ends of some contact elastic sheets 203 are misaligned with the fixed sheet 202. At this time, the series circuit is in an open circuit state, and the limit post 302 is no longer magnetically attracted by the electromagnet 301. The limit post 302 will extend out, blocking the threaded hole on the support block 102, and the fastening bolt 402 cannot be normally installed.;

[0041] Such as Figures 4 to 8As shown, the column head limiting member 4 includes two welding positioning plates 401 respectively attached to the side surfaces of the two support blocks 102; the two welding positioning plates 401 are respectively located between the two limiting blocks 1021 on the same side; the structures on the two welding positioning plates 401 are the same; a fastening bolt 402 is inserted into the welding positioning plate 401; the fastening bolt 402 is threadedly connected to a threaded hole on the support block 102; the threaded hole on the support block 102 is aligned with the limiting column 302; a bushing 403 is fixedly installed on the welding positioning plate 401; a roller shaft 104 is sleeved inside the bushing 403; the column head limiting member 4 further includes a positioning bolt 404 threadedly connected to the bushing 403; the end of the positioning bolt 404 is pressed against and fits the roller shaft 104; the bushing 403 is used to position the roller shaft 104; the inner side of the welding positioning plate 401 is used to fit the outer side of the limiting roller steel pipe 103; the negative pressure member 5 includes a negative pressure adsorption shell 501 fixedly installed on the roller steel pipe 103; the outside of the negative pressure adsorption shell 501 is connected to an air suction pump 502 through a hose; the air suction pump 502 is externally connected to a power supply; the negative pressure member 5 further includes a prompt disk 5011 fixedly installed on the negative pressure adsorption shell 501; a circle of scales is provided on the prompt disk 5011. By using the negative pressure member 5, the fumes generated during welding can be absorbed inside the roller steel pipe 103. The air pressure can be circulated through the weld during welding, and the fumes can be absorbed inside without affecting the operation of the staff during welding and without external interference. At the same time, the air suction is more direct, avoiding the interference with welding when the air suction hood is set outside at a close distance and the fume leakage easily caused when it is at a far distance. The air suction pump 502 can be placed outdoors for discharge. At the same time, by using the column head limiting member 4, the roller shaft 104 and the roller steel pipe 103 can be quickly positioned, facilitating the stable operation of the staff during welding. The structure is simple and the operation is convenient, ensuring the welding accuracy. The two ends of the roller steel pipe 103 are fitted and positioned by using the welding positioning plate 401. At this time, the roller steel pipe 103 and the roller shaft 104 are coaxial, and the staff can operate to carry out the welding work. When welding the weld on the upper part of the roller shaft 104 and it is necessary to rotate the roller shaft 104 to adjust the welding area, the positioning bolt 404 and the fastening bolt 402 can be loosened for quick adjustment. During the process, the air suction pump 502 can continuously suck air, and the air pressure can circulate and extract the fumes from the weld between the roller steel pipe 103 and the roller shaft 104.

[0042] As Figures 4 to 10As shown in the figure, the inner seam detector 6 includes a telescopic shaft 601 slidably inserted into the negative pressure adsorption shell 501; a row of axial scales 6011 are provided on the telescopic shaft 601; a radial scale 6012 is provided on the telescopic shaft 601; a spherical protrusion is provided at the tail of the telescopic shaft 601; two ventilation grooves 6013 are provided on the telescopic shaft 601; the telescopic shaft 601 passes through a through hole on the roller shaft 104; the two ventilation grooves 6013 are respectively used for ventilation; the inner seam detector 6 further includes a swing rod 602 rotatably installed at the end of the telescopic shaft 601; both sides of the end of the swing rod 602 are inclined surface structures; a magnet 603 is fixedly installed on the swing rod 602; the inner side of the magnet 603 is magnetically attracted and attached to the inner side of the roller shaft 104; the end of the swing rod 602 is attached to the inner side of the roller steel pipe 103; the swing rod 602 is used to detect weld penetration. By using the inner seam detector 6, the detection work on the inner side of the weld can be realized, which can avoid the poor temperature control during the welding operation of the staff, resulting in too large depth of the weld and poor flatness of the inner side of the weld. It is more convenient to inspect the inner side of the weld, improve the operation quality of the staff during welding. At the same time, this structure can be used multiple times. By rotating the handheld telescopic shaft 601, the swing rod 602 is driven to swing back and forth inside the roller shaft 104. Once there is a protrusion of the melt caused by poor welding stability control on the inner side of the weld, such as Figure 11 As shown in the figure, at this time, the swing rod 602 will be stuck when swinging, or the magnet 603 cannot completely fit the inner side of the roller shaft 104. When the end of the swing rod 602 is blocked and lifted by the welding melt and is in a skewed state, at this time, the swing rod 602 will drive the telescopic shaft 601 to have an axial displacement. By cooperating with the axial scale 6011, the data change can be observed, and the existence of a molten protrusion inside can be known from the touch feeling of the staff when it is stuck. It is more suitable for the quality inspection of the surfacing welding process.

[0043] The working principle provided by the present invention is as follows. First, the drum steel pipe 103 is passed through a circle of electrical connection elastic pieces 203 from one side of the arc-shaped piece 204. The arc-shaped piece 204 can facilitate the passing of the drum steel pipe 103 by using its arc structure to prevent jamming. The drum steel pipe 103 is placed between two support blocks 102. At this time, if the bending of the drum steel pipe 103 exceeds the standard, the drum steel pipe 103 is no longer concentric with the positioning sleeve 201. The circle of electrical connection elastic pieces 203 still elastically fits on the drum steel pipe 103, but due to non-concentricity, the ends of some electrical connection elastic pieces 203 are misaligned with the fixed piece 202. At this time, the series circuit is in an open circuit state, the electromagnet 301 is powered off, and the limit post 302 is no longer magnetically attracted by the electromagnet 301. Under the extrusion of the return spring 303, the limit post 302 will extend out and block the threaded hole on the support block 102. Only after the staff straightens the drum steel pipe 103 can the ends of the circle of electrical connection elastic pieces 203 be respectively attached to the ends of the circle of fixed pieces 202, and the limit post 302 can be magnetically attracted and retracted by the electromagnet 301, so that the fastening bolt 402 can be normally installed. After the staff places the drum steel pipe 103 on the support block 102, the two welding positioning plates 401 can be respectively placed between the two limit blocks 1021 on the same side for limiting. The drum shaft 104 can be inserted into the shaft sleeve 403 first, and the positioning bolt 404 can be tightened for positioning and pressing. Then, the fastening bolt 402 is threadedly connected to the support block 102, and the welding positioning plate 401 is tightened and pressed to fit and position both ends of the drum steel pipe 103. At this time, the drum steel pipe 103 and the drum shaft 104 are coaxial, and the staff can operate to carry out the welding work. As the welding of the upper weld of the drum shaft 104 is carried out and the welding area needs to be adjusted by rotating the drum shaft 104, the positioning bolt 404 and the fastening bolt 402 can be loosened for quick adjustment. During the process, the air suction pump 502 can continuously suck air, and through the negative pressure adsorption shell 501, real-time negative pressure suction is carried out. With the openings provided on the drum shaft 104, the air pressure can flow through the weld between the drum steel pipe 103 and the drum shaft 104 to achieve the extraction of fumes. By rotating the handheld telescopic shaft 601, the swing rod 602 is driven to swing back and forth inside the drum shaft 104, and the magnet 603 is magnetically attracted and attached to the drum shaft 104. Once there is a protrusion of the melt caused by poor welding stability control inside the weld, such as attached Figure 11As shown, at this time, the swing rod 602 will get stuck during swinging, or the magnet 603 cannot fully fit the inner side of the roller shaft 104. When the end of the swing rod 602 is blocked and lifted by the welding melt and is in a skewed state, the swing rod 602 will drive the telescopic shaft 601 to have an axial displacement at this time. By cooperating with the axial scale 6011, the data change can be observed, and the presence of a molten bulge inside can be known from the touch feeling of the staff when it gets stuck. The radial scale 6012 can facilitate the staff to understand the position of the swing rod 602. The operation is simple and convenient. By rotating the swing rod 602 which is rotatably connected, the staff can directly operate to pull out the telescopic shaft 601 subsequently, so that the magnet 603 is separated from the roller shaft 104. At this time, when pulling out the telescopic shaft 601, the swing rod 602 is squeezed by the edge of the through hole on the roller shaft 104, and then it can rotate coaxially with the telescopic shaft 601, and can be quickly disassembled and pulled out.
