Description

Technical Field

[0001] This application relates to the technical field of air storage tank welding, and particularly relates to an auxiliary device for welding the air storage tank cylinder body. Background Art

[0002] The air storage tank is a gas storage device in the vehicle braking system. The air storage tank is used to store the gas compressed by the air compressor and is used in systems such as vehicle braking and horn sounding. The air storage tank is a container that can store and release gas, and its principle is similar to that of a water storage tank.

[0003] During the production and processing of the air storage tank, it is necessary to weld two semi-circular cylinder bodies to assemble the two semi-circular cylinder bodies into a complete cylinder body. At the same time, when welding the two semi-cylinder bodies, it is usually necessary to perform synchronous welding on the inner and outer sides of the weld of the cylinder body. On the one hand, although single-sided welding has high efficiency, it will cause cracks on the un-welded side of the cylinder body, making the cylinder body prone to rupture due to low welding strength during subsequent use. On the other hand, synchronous welding inside and outside can ensure the connectivity of the cylinder body welding and avoid the phenomenon of cracking and dislocation due to low connectivity strength during the turning adjustment of the cylinder body to ensure the welding effect of the cylinder body. And usually, double-sided welding will be deformed due to too high welding temperature. Therefore, the two welding heads for welding inside and outside the cylinder body need to be staggered for welding, which can reduce the welding deformation of the cylinder body while ensuring the welding quality of the cylinder body. At the same time, in order to ensure the filling effect of the air storage tank welding, it is usually necessary to add solder to the weld. On the one hand, it is necessary to ensure the connection strength of the cylinder body weld, and on the other hand, it can improve the surface quality and internal structure of the cylinder body weld.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: when filling solder into the weld, it is usually necessary to fill the amount of solder according to the size of the weld. However, currently, when welding two semi-cylinder bodies, it is not easy to detect and adjust the coaxiality of the two semi-cylinder bodies, resulting in easy misalignment during the welding of the two semi-cylinder bodies, causing errors in the amount of solder filled according to the weld, making the weld expand, become uneven and discontinuous, resulting in excessive solder filling and waste of resources, and the solder cannot be accurately filled into the weld, making the solder prone to random splashing during the welding of the cylinder body, which will cause harm to the staff, and obvious gaps or misalignment marks will appear when the solder adheres outside the weld during welding, affecting the aesthetics of the cylinder body. Summary of the Invention

[0005] In order to solve the problem that it is not easy to detect and adjust the coaxiality of two semi-cylinder bodies during welding, resulting in easy misalignment during the welding of the two semi-cylinder bodies and causing errors in the amount of solder filled according to the weld, this application provides an auxiliary device for welding the air storage tank cylinder body.

[0006] The welding auxiliary device for the air storage cylinder barrel provided by this application adopts the following technical solution: A welding auxiliary device for an air storage cylinder barrel, comprising a welding frame, a rotating assembly, a translation assembly, a welding part and a cooling assembly for rotating, translating, welding and cooling the barrel, a filling assembly, a detection assembly and a marking assembly for automatically filling, detecting and marking the weld seam of the barrel; The rotating assembly includes two rotating wheels rotatably arranged on the welding frame, a rotating part for synchronously driving the two rotating wheels to rotate, and a detection part for respectively detecting the weights of the two rotating wheels; The translation assembly includes a pushing frame rotatably arranged on the welding frame, a pushing part for driving the pushing frame to rotate, and a positioning part for positioning the barrel; The filling assembly includes two filling boxes movably arranged on the welding frame, a plurality of filling blocks respectively movably arranged on the two filling boxes, an extrusion part for driving the extrusion of the plurality of filling blocks, and a filling part for automatically filling the two filling boxes with welding material; The cooling assembly includes a first cooling plate and a second cooling plate movably arranged on the welding frame, and a cooling part for filling the first cooling plate and the second cooling plate with cooling liquid; The detection assembly includes two rotating plates respectively rotatably arranged on the two filling boxes, two adjusting rods respectively slidably arranged on the two rotating plates, and a driving part for respectively driving the rotation of the two rotating plates.

[0007] By adopting the above technical solution, the rotating assembly can rotate and adjust the barrel, and at the same time can detect the weight of the barrel. The translation assembly can translate and push the barrel, and at the same time can position the barrel to avoid the phenomenon of the barrel shifting during welding; the filling assembly can automatically fill the weld seam of the barrel; the cooling assembly can cool the barrel, and at the same time can block the barrel to avoid the phenomenon of leakage during barrel welding; the detection assembly can detect the weld seam of the barrel, and the marking assembly can mark the barrel, so as to facilitate the staff to quickly detect and repair the weld seam of the welded barrel, and the welding part can weld the barrel. When welding two semi-cylinders, usually butt welding is adopted vertically. However, when welding vertically, it is usually impossible to weld the bottom weld because the bottom weld usually fits against the fixture or support table, which easily causes interference during the welding of the bottom of the two semi-cylinders and cannot complete the welding of the two semi-cylinders at one time. By welding the two semi-cylinders with their left and right sides aligned, the one-time welding of the two welds of the two semi-cylinders can be completed. When performing double-sided welding on the two semi-cylinders, usually the welds of the two semi-cylinders need to be accurately fitted against the welding device to avoid misalignment during welding. By adjusting the angle of the semi-cylinder, the side of the semi-cylinder can be accurately aligned with the two welding devices first, and at the same time, the upper cylinder is corrected to make the two semi-cylinders accurately aligned, avoiding misalignment during welding and causing interference to the welding of the cylinder.

[0008] Optionally, a power member for driving the two stuffing boxes, the first cooling plate and the second cooling plate to translate and an adjusting member for driving the power member to translate are further provided on the welding frame; The power member includes a connecting frame movably arranged on the welding frame, a bidirectional screw rod rotatably arranged on the connecting frame, and a servo motor fixed on the connecting frame. The bidirectional screw rod is fixedly connected to the output shaft of the servo motor, and the two stuffing boxes, the first cooling plate and the second cooling plate are all threadedly connected to the bidirectional screw rod.

[0009] By adopting the above technical solution, the power member can drive the two stuffing boxes, the first cooling plate, the second cooling plate, the welding member and the cleaning member to translate. The servo motor can drive the bidirectional screw rod to rotate, and then drive the two stuffing boxes, the first cooling plate and the second cooling plate to move, so that the two stuffing boxes can be respectively fitted against the outer wall and the inner wall of the cylinder, the first cooling plate is fitted against the inner wall of the cylinder, and the second cooling plate is fitted against the outer wall of the cylinder. When filling the cylinder with solder, the two stuffing boxes, the first cooling plate and the second cooling plate are all fitted against the cylinder, and the two stuffing boxes can cooperate with the first cooling plate and the second cooling plate respectively, which can avoid the situation of leakage when filling the solder into the weld of the cylinder.

[0010] Optionally, the adjusting member includes a threaded rod rotatably arranged on the welding frame and a driving motor fixed on the welding frame. The threaded rod is fixedly connected to the output shaft of the driving motor, and the connecting frame is threadedly connected to the threaded rod.

[0011] By adopting the above technical solution, the adjusting member can drive the two stuffing boxes, the first cooling plate, the second cooling plate, the welding member and the cleaning member to translate on the cylinder body. The driving motor can drive the threaded rod to rotate, and then can drive the connecting frame, the two stuffing boxes, the first cooling plate, the second cooling plate, the welding member and the cleaning member to translate at the weld of the cylinder body in sequence. At the same time, when the cylinder body is misaligned and adjusted, the adjusting rod can be moved to the smooth part of the cylinder body to facilitate the complete stuffing, welding cooling and cleaning of the two welds on the cylinder body.

[0012] Optionally, the rotating member includes two driven wheels rotatably arranged on the welding frame, two transmission belts, a driving wheel and a motor fixed on the welding frame. The two driven wheels are coaxially fixed with the two rotating wheels respectively. The two driven wheels are respectively connected with the two transmission belts in a transmission manner. Both of the two transmission belts are connected with the driving wheel in a transmission manner. The driving wheel is fixedly connected with the output shaft of the motor. The detecting member includes two weight sensors and two telescopic springs fixed on the welding frame, and support frames respectively fixed on the two telescopic springs. The two rotating wheels are respectively rotatably connected with the two support frames. The two support frames are respectively in movable contact with the two weight sensors. Both of the two rotating wheels are in movable contact with the cylinder body.

[0013] By adopting the above technical solution, the rotating member can adjust the angles of the semi-cylinder body and the complete cylinder body on the two rotating wheels. The motor can drive the driving wheel, the two transmission belts, the two driven wheels and the two rotating wheels to rotate in sequence. Then, when the two rotating wheels rotate synchronously, the angle of the semi-cylinder body or the cylinder body can be adjusted. The detecting member can detect the forces borne by the two rotating wheels, and can judge whether the semi-cylinder body on the two rotating wheels is in a flat state. When the force received by the left rotating wheel is greater than that received by the right rotating wheel, the motor can be used to drive the two rotating wheels to rotate clockwise. When the force received by the right rotating wheel is greater than that received by the left rotating wheel, the motor can be used to drive the two rotating wheels to rotate counterclockwise. When the forces borne by the two weight sensors are the same, it indicates that the semi-cylinder body on the two rotating wheels is in a flat state.

[0014] Optionally, the driving member includes two pressure sensors respectively fixed on the two stuffing boxes and first springs respectively fixed on the four adjusting rods. The four pressure sensors are respectively fixedly connected with the four first springs. The two adjusting rods on the left are both in movable contact with the outer wall of the cylinder body. The two adjusting rods on the right are both in movable contact with the inner wall of the cylinder body.

[0015] By adopting the above technical solution, the driving member can detect whether the upper cylinder body and the lower cylinder body are misaligned. When the power member drives the adjusting rod to fit with the cylinder body, the first spring will be in a compressed state. Correspondingly, the first spring will drive the corresponding pressure sensor. If the upper cylinder body and the lower cylinder body are not misaligned, the forces received by the two adjusting rods that fit with the outer side of the cylinder body and the two adjusting rods that fit with the inner side of the cylinder body are the same. Furthermore, the forces exerted by the two first springs on the two pressure sensors are also the same, and there is no need to push for deviation correction. If the upper cylinder body and the lower cylinder body are misaligned, the forces received by the two adjusting rods that fit with the outer side of the cylinder body and the two adjusting rods that fit with the inner side of the cylinder body are different, and the forces exerted by the two first springs on the two pressure sensors are also different. Through the forces borne by the upper and lower pressure sensors, the pushing member can be driven to correct the deviation of the upper cylinder body.

[0016] Optionally, the pushing member includes a rotary motor fixed to the welding frame, the pushing frame is fixedly connected to the output shaft of the rotary motor, the pushing frame is movably attached to the outer wall of the cylinder body, and the four pressure sensors are all electrically connected to the rotary motor.

[0017] By adopting the above technical solution, the pushing member can push the upper half cylinder body for deviation correction, so that the upper cylinder body and the lower cylinder body can be completely fitted together. When the driving member detects that the upper half cylinder body deviates to the right, the rotary motor can drive the pushing frame to swing clockwise and push the upper half cylinder body to the left. When it is detected that the upper half cylinder body deviates to the left, the rotary motor can drive the pushing frame to swing counterclockwise and push the upper half cylinder body to the right. With the electrical induction of the four pressure sensors and the rotary motor, it can be detected whether the upper half cylinder body and the lower half cylinder body are completely fitted together.

[0018] Optionally, the marking assembly includes two marker pens respectively movably arranged on the two stuffing boxes and a translation member for driving the translation of the two marker pens; the translation member is driven by a driving member. The translation member includes two second springs respectively fixed to the two stuffing boxes. The four second springs are respectively fixedly connected to the four marker pens. The two marker pens on the left are both movably attached to the left rotating plate, and the two marker pens on the right are both movably attached to the right rotating plate.

[0019] By adopting the above technical solution, the translation part can detect the marks beside the weld of the cylinder body. While the pushing parts detect two welds on the cylinder body respectively, they can indirectly drive four marker pens to detect the marks at the welding parts of the cylinder body. If the two semi-cylinder bodies are misaligned or there are bumps and pits beside the welds of the two semi-cylinder bodies, making the two adjusting rods unable to reach balance, it will drive the angle of the rotating plate to swing. When the rotating plate swings, it will push the marker pen to move, making the second spring in a compressed state, so that the marker pen can be in contact with the cylinder body, and the corresponding defective parts of the cylinder body can be marked, so as to facilitate the staff to quickly find the positions of the corresponding defects of the cylinder body for grinding and welding repair.

[0020] Optionally, the extrusion parts include sensors respectively fixed on two stuffing boxes and compression springs respectively fixed on multiple stuffing blocks. The number of the multiple stuffing blocks and the multiple compression springs are both divided into two groups. The two groups of compression springs are respectively fixedly connected with the two sensors, the two groups of stuffing blocks are respectively in movable contact with the two sensors, and the two stuffing boxes are respectively in movable contact with the inner wall and the outer wall of the cylinder body.

[0021] By adopting the above technical solution, the extrusion parts can extrude the solder in the two stuffing boxes into the weld of the cylinder body. When the solder fills the two stuffing boxes, it will squeeze the multiple stuffing blocks on the two stuffing boxes, making the multiple compression springs on the two stuffing boxes in a squeezed state, and making the two groups of stuffing blocks respectively in contact with the two sensors, indicating that the solder in the two stuffing boxes has been filled. When the two stuffing boxes move, the two groups of stuffing blocks can be driven to move respectively by the thrust of the two groups of compression springs, and the solder can be extruded into the weld between the two semi-cylinder bodies, and the automatic stuffing of the weld can be completed. While the two groups of stuffing blocks are extruding the solder, the stuffing blocks will separate from the sensors, which can drive the solenoid valves to open, and at the same time can drive the feeding pump to fill the stuffing boxes with solder.

[0022] Optionally, the filling parts include a storage box fixed on the welding frame, a connecting hose fixed on the storage box, two solenoid valves and a feeding pump fixed on the connecting hose. The two stuffing boxes are both communicated with the connecting hose, the connecting hose is communicated with the storage box, the two solenoid valves are respectively electrically connected with the two sensors, and the two sensors are both electrically connected with the feeding pump.

[0023] By adopting the above technical solution, the filling parts can continuously supply materials to the two stuffing boxes. The feeding pump can pump the solder in the storage box into the two stuffing boxes through the connecting hose, and the two solenoid valves can respectively control the opening and closing of the connection ports between the connecting hose and the two stuffing boxes, and can continuously fill the two storage boxes with materials.

[0024] Optionally, the cooling member includes a fixed hose fixed to the first cooling plate. The first cooling plate and the second cooling plate are both communicated with the fixed hose. The first cooling plate is movably attached to the inner wall of the cylinder body, and the second cooling plate is movably attached to the outer wall of the cylinder body.

[0025] By adopting the above technical solution, the cooling member can cool the cylinder body while welding the outer side and the inner side of the cylinder body, which can avoid the phenomenon of leakage when the extruding member adds flux to the weld of the cylinder body. Pour the coolant into the inner sides of the first cooling plate, the fixed hose and the second cooling plate in sequence, so that the coolant fills and cools the first cooling plate and the second cooling plate. Since the first cooling plate and the second cooling plate move synchronously, when the two stuffing boxes fill the weld, the first cooling plate and the second cooling plate can plug the other side of the weld of the cylinder body to prevent the solder from leaking from the other side of the weld when the two stuffing boxes fill the weld.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The detecting member and the rotating member can adjust the angle of the semi-cylinder body, and the semi-cylinder body can be adjusted to a flat state to avoid the semi-cylinder body being in an inclined state, which may cause interference to the subsequent complete welding of the cylinder body. The positioning member can clamp and fix the adjusted semi-cylinder body, and then place the other semi-cylinder body on the adjusted semi-cylinder body to form a complete cylinder body. The power member and the driving member can detect whether the upper cylinder body and the lower cylinder body are misaligned. If misaligned, the upper semi-cylinder body can be pushed to make the two semi-cylinder bodies fit together completely, so as to avoid the generation of gaps due to the misalignment of the upper semi-cylinder body and the lower semi-cylinder body when the stuffing box adds solder, and prevent the solder from leaking during stuffing. After complete splicing, the positioning member can clamp and fix the top semi-cylinder body; 2. The adjusting member and the filling member can fill the solder in the two stuffing boxes. The extruding member can extrude the solder into the weld between the two semi-cylinder bodies to complete the automatic filling of the weld. On the one hand, it can ensure the supply of solder in the weld by the two stuffing boxes. On the other hand, it can avoid waste caused by excessive filling of solder. Filling the inner and outer sides of the cylinder body can ensure the filling effect of the solder in the weld of the cylinder body. Even if the weld shape of the cylinder body is uneven, the two welding devices can respectively weld the two welds of the cylinder body, and can synchronously weld the inside and outside of the cylinder body to weld the two semi-cylinder bodies together; 3. While the two welding devices respectively weld the inner wall and the outer wall of the cylinder body, the cooling member can be used to cool the cylinder body, and can also cooperate with the two stuffing boxes to plug the other side of the weld while filling the weld of the cylinder body to ensure the welding effect of the weld of the cylinder body; 4. While the driving member detects two weld seams on the cylinder body, it can also indirectly drive four marking pens to detect the welding points on the cylinder body. The translation member can mark the corresponding defective parts of the cylinder body, so that the staff can quickly find the positions of the corresponding defects on the cylinder body for grinding and welding repair. The rotating member can adjust the angle of the welded cylinder body. Through the above principle, the filler, welding, cooling and marking detection of the weld seams on the outer side and the other side of the inner side of the cylinder body can be carried out respectively, achieving the effect of double-sided offset welding of the cylinder body, and avoiding damage to the cylinder body caused by excessive temperature during double-sided welding.

When the forces borne by the two weight sensors 9 are the same, it means that the semi-barrel 2 on the two rotating wheels 7 is in a flat state, and there is no need to drive the two rotating wheels 7 to rotate. When it is detected that the force-bearing degrees of the two rotating wheels 7 detected by the two weight sensors 9 are inconsistent, the motor 3 can drive the driving wheel 4, two transmission belts 5, two driven wheels 6 and two rotating wheels 7 to rotate in sequence. When the force-bearing degree of the left rotating wheel 7 is greater than that of the right rotating wheel 7, the motor 3 can drive the two rotating wheels 7 to rotate clockwise. When the force-bearing degree of the right rotating wheel 7 is greater than that of the left rotating wheel 7, the motor 3 can drive the two rotating wheels 7 to rotate counterclockwise, so as to adjust the angle of the barrel 2 on the two rotating wheels 7, so as to adjust the semi-barrel 2 to a flat state, avoid the semi-barrel 2 being in an inclined state, and cause interference to the subsequent complete welding of the barrel 2. After the semi-barrel 2 is adjusted to a flat state, the semi-barrel 2 can be clamped and fixed by rotating the bottom movable screw frame 37 and cooperating with the bottom connecting bracket 39, so as to avoid the semi-barrel 2 being offset during the welding and assembly. (2) Then, place the other half cylinder 2 above the adjusted half cylinder 2 by machine to form a complete cylinder 2. The servo motor 14 can drive the bidirectional screw 15 to rotate, and then drive the two stuffing boxes 16, the two welders 35, the first cooling plate 17 and the second cooling plate 18 to move. Thus, the two stuffing boxes 16 can be respectively attached to the outer wall and the inner wall of the cylinder 2, the first cooling plate 17 is attached to the inner wall of the cylinder 2, and the second cooling plate 18 is attached to the outer wall of the cylinder 2. The two adjusting rods 28 on the left are respectively attached to the outer walls of the two half cylinders 2, and the two adjusting rods 28 on the right are respectively attached to the inner walls of the two half cylinders 2. When the adjusting rod 28 is closely attached to the cylinder 2, the first spring 29 will be in a compressed state. Correspondingly, the first spring 29 will drive the corresponding pressure sensor 30, which can detect whether the upper cylinder 2 and the lower cylinder 2 are misaligned. If the upper cylinder 2 and the lower cylinder 2 are not misaligned, the forces received by the two adjusting rods 28 attached to the outer side of the cylinder 2 and the two adjusting rods 28 attached to the inner side of the cylinder 2 are also the same. The pressures received by the corresponding two first springs 29 are also the same. Furthermore, the forces exerted by the two first springs 29 on the two pressure sensors 30 are also the same, indicating that the upper cylinder 2 and the lower cylinder 2 have been joined into a complete cylinder 2 and no pushing and rectifying is required. If the upper cylinder 2 and the lower cylinder 2 are misaligned, the forces received by the two adjusting rods 28 attached to the outer side of the cylinder 2 and the two adjusting rods 28 attached to the inner side of the cylinder 2 are different. The pressures received by the corresponding two first springs 29 are also different. Furthermore, the forces exerted by the two first springs 29 on the two pressure sensors 30 are also different. Through the forces borne by the upper and lower pressure sensors 30, the rotation motor 33 can be driven to rotate clockwise or counterclockwise. When the upper cylinder 2 deviates to the left, the upper adjusting rod 28 will drive the upper first spring 29 to increase the force exerted on the upper pressure sensor 30, driving the rotating plate 27 to swing counterclockwise. The force exerted by the lower adjusting rod 28 and the lower first spring 29 on the lower pressure sensor 30 remains unchanged, and the pressure sensor 30 can drive the rotation motor 33 to rotate counterclockwise. When the upper cylinder 2 deviates to the right, the lower adjusting rod 28 will drive the lower first spring 29 to increase the force exerted on the lower pressure sensor 30, driving the rotating plate 27 to swing clockwise. The force exerted by the upper adjusting rod 28 and the upper first spring 29 on the upper pressure sensor 30 remains unchanged, and the rotation motor 33 can be driven to rotate clockwise. By setting the pressure sensors 30, the first springs 29 and the adjusting rods 28 in both stuffing boxes 16, the effect and accuracy of detecting the deviation of the cylinder 2 can be enhanced, and it can be prevented that when one group of pressure sensors 30 is damaged, the other group can continue to be used for detection; (3)When it is detected that the upper half cylinder 2 deviates to the right, the rotation of the rotating motor 33 can drive the pushing frame 34 to swing clockwise, and then the upper half cylinder 2 can be pushed to the left. When it is detected that the upper half cylinder 2 deviates to the left, the rotation of the rotating motor 33 can drive the pushing frame 34 to swing counterclockwise, and then the upper half cylinder 2 can be pushed to the right. Thus, in cooperation with the electrical induction of the four pressure sensors 30 and the rotating motor 33, it can be detected whether the upper half cylinder 2 and the lower half cylinder 2 are completely fitted together, and it can be judged whether the upper half cylinder 2 and the lower half cylinder 2 are misaligned. Even if the upper half cylinder 2 and the lower half cylinder 2 are misaligned, by the induction of the four pressure sensors 30 to drive the rotating motor 33 to drive the pushing frame 34 to rotate clockwise or counterclockwise, the upper half cylinder 2 and the lower half cylinder 2 can also be completely fitted together, preventing the packing box 16 from generating gaps due to the misalignment of the upper half cylinder 2 and the lower half cylinder 2 when adding solder, and avoiding the leakage of solder during filling. When the upper half cylinder 2 and the lower half cylinder 2 are adjusted to form a complete cylinder 2, by rotating the top movable screw frame 37 and cooperating with the top connecting bracket 39, the top half cylinder 2 can be clamped and fixed, preventing the top half cylinder 2 and the bottom half cylinder 2 from being offset during welding and assembly; (4) The driving motor 11 can drive the threaded rod 12 to rotate, and then can drive the connecting frame 13, two stuffing boxes 16, two welders 35, the first cooling plate 17 and the second cooling plate 18 to translate in sequence. The feeding pump 24 can pump the solder in the storage tank 23 into the two stuffing boxes 16 through the connecting hose 25. The two solenoid valves 26 can respectively control the opening and closing of the connecting ports of the connecting hose 25 and the two stuffing boxes 16. When the solder fills the two stuffing boxes 16, it will respectively squeeze the multiple stuffing blocks 21 on the two stuffing boxes 16, making the multiple compression springs 20 on the two stuffing boxes 16 in a squeezed state, so that the two groups of stuffing blocks 21 are respectively in contact with the two sensors 19, indicating that the solder in the two stuffing boxes 16 has been filled. Furthermore, when the two stuffing boxes 16 translate, they can automatically fill the solder in the weld between the upper cylinder body 2 and the lower cylinder body 2. Since the two groups of stuffing blocks 21 are both located between the welds of the upper cylinder body 2 and the lower cylinder body 2, when the two stuffing boxes 16 move, the two groups of stuffing blocks 21 can be driven to move respectively by the thrust of the two groups of compression springs 20, and the solder can be squeezed and extruded into the weld between the upper cylinder body 2 and the lower cylinder body 2, thus completing the automatic stuffing of the weld. At the same time, when the two groups of stuffing blocks 21 squeeze the solder, the stuffing blocks 21 will separate from the sensors 19, and then the solenoid valves 26 can be driven to open, and at the same time, the feeding pump 24 can be driven to fill the solder in the stuffing boxes 16. By this method, the solder can be quantitatively filled in the weld. When the stuffing blocks 21 are in contact with the sensors 19, the solenoid valves 26 and the feeding pump 24 can be closed to stop filling the solder in the stuffing boxes 16. On the one hand, it can ensure the supply of solder in the weld by the two stuffing boxes 16. On the other hand, it can avoid waste caused by overfilling the solder and prevent the solder from floating out of the weld due to high pressure. By stuffing both the inside and outside of the cylinder body 2, the filling effect of the solder in the weld of the cylinder body 2 can be ensured. Even if the shape of the weld of the cylinder body 2 is uneven, the double-sided filling of the weld of the cylinder body 2 can also ensure that the weld is filled with solder to ensure the welding effect of the welder 35 on the weld; (5) While the two stuffing boxes 16 are stuffing the weld, the two welders 35 can respectively weld the two welds of the cylinder body 2, and the welding inside and outside the cylinder body 2 can be carried out synchronously to weld the upper cylinder body 2 and the lower cylinder body 2 together; (6)While the two welders 35 weld the inner wall and the outer wall of the cylinder body 2 respectively, the cylinder body 2 can be cooled by the cooling of the first cooling plate 17 and the second cooling plate 18 of the coolant. Since the two stuffing boxes 16, the two welders 35, the first cooling plate 17 and the second cooling plate 18 move synchronously, the coolant can be poured into the inner sides of the first cooling plate 17, the fixed hose 22 and the second cooling plate 18 in sequence through the liquid inlet pipe, so that the coolant fills the first cooling plate 17 and the second cooling plate 18, and the first cooling plate 17 and the second cooling plate 18 can be cooled. Therefore, while the two stuffing boxes 16 fill the weld with filler, the first cooling plate 17 and the second cooling plate 18 can plug the other side of the weld of the cylinder body 2 to prevent the solder from leaking from the other side of the weld when the two stuffing boxes 16 fill the weld with filler. Therefore, the first cooling plate 17 and the second cooling plate 18 can not only cooperate with the two welders 35 to cool while welding the cylinder body 2, but also cooperate with the two stuffing boxes 16 to plug the other side of the weld while filling the weld of the cylinder body 2, so as to ensure the welding effect of the weld of the cylinder body 2; (7)When the two stuffing boxes 16 translate on the cylinder body 2, they will respectively drive the two rotating plates 27, the four adjusting rods 28 and the four marking pens 32 to translate on the cylinder body 2, so as to facilitate the marking detection beside the two welding joints of the cylinder body 2. When the rotating plate 27 and the two adjusting rods 28 fit and detect a weld, if there are concave and convex pits beside the weld of the upper cylinder body 2 and the lower cylinder body 2, when filling the weld with solder, the solder cannot be accurately filled into the solder due to the concave and convex pits, resulting in defects when the welder 35 welds the weld at the concave and convex part. Therefore, when the two adjusting rods 28 move to the concave and convex part, they cannot reach balance, and then drive the rotating plate 27 to swing at an angle. While the rotating plate 27 swings, it will push the marking pen 32 to move, so that the second spring 31 is in a compressed state, and the marking pen 32 can be attached to the cylinder body 2 to mark the corresponding defective part of the cylinder body 2, so as to facilitate the staff to quickly find the position of the corresponding defect of the cylinder body 2 for grinding and welding repair. When there is a concave pit below the cylinder body 2 or a convexity above the cylinder body 2, the first spring 29 will drive the rotating plate 27 to rotate counterclockwise, so that the marking pen 32 located below can be attached to the cylinder body 2 for marking. When there is a concave pit above the cylinder body 2 or a convexity below the cylinder body 2, the first spring 29 will drive the rotating plate 27 to rotate clockwise, so that the marking pen 32 located above can be attached to the cylinder body 2 for marking, which speeds up the effect of the staff's judgment and search for the defects at the specified position of the cylinder body 2. At the same time, when the lower and upper parts of the cylinder body 2 are in a flat state, the two adjusting rods 28 will remain balanced, and then will not drive the rotating plate 27 to rotate, nor drive the marking pen 32 to be attached to the cylinder body 2. The four marking pens 32 can be used for marking detection during the welding of the inner and outer sides of the cylinder body 2; (8) After the two welding machines 35 have welded one side of the outer side of the cylinder body 2 synchronously, first, the two electromagnets 38 lose suction on the two connecting brackets 39 respectively, and then the motor 3 starts the two rotating wheels 7 to rotate through the above principle. Furthermore, the cylinder body 2 can be driven to rotate, and the angle of the cylinder body 2 can be adjusted. Because the cylinder body 2 has been welded on the outside and inside on one side at this time, the upper cylinder body 2 and the lower cylinder body 2 are welded together. Therefore, when the cylinder body 2 is adjusted at this time, the upper cylinder body 2 and the lower cylinder body 2 will not be separated. After the cylinder body 2 is adjusted, it is not necessary to push and align the upper cylinder body 2 again. When the upper connecting bracket 39 fits and senses the lower electromagnet 38, and the lower connecting bracket 39 fits and senses the upper electromagnet 38, it means that the cylinder body 2 has just rotated 180 degrees. At this time, the two solenoid valves 26 are driven again to adsorb the two connecting brackets 39 respectively, and the cylinder body 2 can be repositioned to avoid the phenomenon that the cylinder body 2 shifts when the two stuffing boxes 16 and the two welding machines 35 fill and weld the other weld seams on the outer and inner sides of the cylinder body 2 respectively. At the same time, after the cylinder body 2 rotates 180 degrees, through the above principle, the two stuffing boxes 16 and the two welding machines 35 can fill, weld, cool and mark and detect the weld seams on the other side of the outer and inner sides of the cylinder body 2 respectively, achieving the effect of double-sided staggered welding of the cylinder body 2 and avoiding damage to the cylinder body 2 caused by excessive temperature during double-sided welding.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
