[0002] The pump housing is the outer shell of a water pump or air pump, which is used to protect the precise and important structures inside the pump. When the water pump or air pump is used for a long time, the pump housing is prone to breakage or depression. Without affecting the overall use of the pump housing and ensuring its continued use, the pump housing needs to be repaired. The damaged part of the pump housing is cut off using a cutting machine, and a new housing is welded using a brazing machine to repair the pump housing so that it can continue to be used.

[0003] A patent with the publication number CN116967550B discloses a pump housing welding device, which includes a bottom plate. Three rotating rollers are fixedly sleeved on the outer surface of the driving shaft. The upper part of the rotating roller is exposed outside the support frame. A gravity rod is movably installed vertically below the rotating roller through a telescopic mechanism. The present invention has the function of quickly positioning the column housing and the metal ring body, which brings convenience to welding and eliminates the preliminary welding and fixing steps of workers in the traditional process; it can automatically perform full welding at the connection between the column housing and the metal ring body to ensure the sealing degree of the connection; during the process of positioning the column housing and the metal ring body, the tightening degree can be flexibly adjusted to prevent scratching the workpiece to be processed during rotation.

[0004] Currently, after some pump housings are used, breakage or notches may appear on the side of the pump housing. The damaged housing after cutting off the damaged part needs to be fixed on the brazing equipment. The size of the notch on the damaged housing is measured, and then a steel sheet of the corresponding size is cut from the steel strip using a cutting machine. After the steel sheet is fixed to the damaged housing, the steel sheet and the damaged housing are welded using a brazing machine to complete the repair and reuse of the pump housing. However, when the damaged housing is manually positioned and fixed by workers and the notch size is measured, there will be a problem that the measured size is inaccurate, resulting in the steel sheet not being able to fit and weld with the notch of the damaged housing. Moreover, the operation process of fixing the steel sheet and the damaged housing through fixing bolts and then welding the steel sheet and the damaged housing is complex, resulting in low efficiency of repairing and reusing the pump housing.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 9 shown, a pump shell welding machine according to an embodiment of the present invention includes a welding table 1. A detection device is provided on the lower side of the welding table 1. The detection device includes a plurality of clamping blocks 24 slidably connected to the lower side of the welding table 1. Rubber sleeves 25 are provided in each of the plurality of clamping blocks 24. Air cushions 26 are provided on one side of the rubber sleeves 25 in each of the plurality of clamping blocks 24. A plurality of buttons 34 are provided in each of the plurality of rubber sleeves 25. The detection device moves the air cushions 26 through the plurality of clamping blocks 24 to detect the notch of the broken housing 28. A steel coil 3 is placed on the upper side of the welding table 1. A cutting device is provided on the upper side of the welding table 1. The cutting device is used to cut the steel coil 3 into steel sheets 37 matching the notch of the broken housing 28. A feeding device is provided on the upper side of the welding table 1. The feeding device is used to move the steel sheets 37 to the notch of the broken housing 28. An electric rail 36 is provided on the lower side of the welding table 1. A welding device is provided on the lower side of the electric rail 36. The welding device is a brazing device.

[0023] Specifically, after some pump casings are used, breakages or notches will appear on the side of the pump casing. The damaged part of the pump casing is cut off by a cutting device to form a broken casing 28. Then, the broken casing 28 is fixed on a brazing device, the notch size is measured, and a steel sheet 37 of a corresponding size is cut from the steel strip 3 by the cutting device. After the steel sheet 37 is fixed to the broken casing 28, a brazing machine is used to weld the steel sheet 37 and the broken casing 28 to complete the repair and reuse of the pump casing. When the staff manually locates and fixes the broken casing 28 and measures the notch size, there will be a problem that the measured size is inaccurate, resulting in the inability of the cut steel sheet 37 to fit and weld with the notch of the broken casing 28. Moreover, the operation process of fixing the steel sheet 37 and the broken casing 28 with fixing bolts and then welding the steel sheet 37 and the broken casing 28 is complicated, resulting in low efficiency of repairing and reusing the pump casing.

[0024] In this embodiment, first, the broken casing 28 is placed on the welding table on the lower side of the welding table 1. Through the detection device, a plurality of clamping blocks 24 drive the air cushions 26 to move towards the center and press against the side of the broken casing 28. When the air cushion 26 is completely compressed into the clamping block 24 and presses all the buttons 34 through the rubber sleeve 25, it indicates that the side of the broken casing 28 pressed by the air cushion 26 here is intact. When the air cushion 26 is not completely squeezed back into the clamping block 24, the air cushion 26 cannot completely press all the buttons 34, which indicates that there is a notch on the side of the broken casing 28 pressed by the air cushion 26. Then, the steel coil 3 is cut into a steel sheet 37 matching the notch of the broken casing 28 by a cutting device, and the steel sheet 37 is fed to the notch of the broken casing 28 by a feeding device. The brazing head of the welding device welds the steel sheet 37 and the broken casing 28 by brazing. That is, the notch on the side of the broken casing 28 can be detected by the air cushion 26, and the steel sheet 37 is moved to the notch of the broken casing 28 for welding to complete the repair work of the broken casing 28. When fixing the broken casing 28, it is not necessary for the staff to manually locate and fix the broken casing 28. The size of the notch of the broken casing 28 can be directly detected, the steel sheet 37 of the required size is automatically cut and welded with the broken casing 28, and the repair work of the broken casing 28 is better completed, improving the efficiency of welding and repairing the broken casing 28.

[0025] As Figure 9 shown, a plurality of fixing devices are provided on the lower side of the welding table 1. The fixing device includes a third hydraulic cylinder 16 fixedly connected to the lower side of the welding table 1. The output end of the third hydraulic cylinder 16 is fixedly connected with a fixing frame 17. A roller 18 is rotatably connected in the fixing frame 17. After a plurality of rollers 18 move, they abut against the outside of the broken casing 28 to fix the broken casing 28.

[0026] Specifically, after the air cushion 26 detects the notch of the broken housing 28, the second hydraulic cylinder 15 is activated to move the clamping block 24 away from the broken housing 28 with the air cushion 26. Then, the third hydraulic cylinder 16 is activated to move the fixed frame 17 towards the center. The fixed frame 17 holds the broken housing 28 with multiple rollers 18 to prevent the air cushion 26 from being damaged during the welding of the steel sheet 37 to the broken housing 28.

[0027] As Figure 9 shown, a second motor 19 is fixedly connected to one side inside the fixed frame 17. The output end of the second motor 19 is fixedly connected to a first gear 20. A second gear 21 is fixedly connected to one side of the roller 18. The first gear 20 is meshed with the second gear 21.

[0028] Specifically, when the air cushion 26 presses against it, the second motor 19 is activated to rotate the first gear 20. The rotation of the first gear 20 drives the roller 18 to rotate through the second gear 21. The rotation of the roller 18 rotates the broken housing 28 to adjust the notch of the broken housing 28, so that the notch of the broken housing 28 rotates to the specified position for cutting the steel sheet 37. This enables the cut steel sheet 37 to move to the notch of the broken housing 28 faster and more accurately. The rotation of the broken housing 28 also allows the air cushion 26 to comprehensively detect the side of the broken housing 28 and more precisely detect the size of the notch on the side of the broken housing 28.

[0029] As Figure 2 shown, the detection device includes a second hydraulic cylinder 15 fixedly connected inside the welding table 1. The output end of the second hydraulic cylinder 15 is fixedly connected to a lifting plate 22. One side of the lifting plate 22 is rotatably connected to a plurality of connecting rods 23. The plurality of connecting rods 23 are distributed in a circular array. The plurality of connecting rods 23 are all rotatably connected to the clamping block 24.

[0030] Specifically, when moving the clamping block 24 to detect the broken housing 28, the second hydraulic cylinder 15 is activated to pull the clamping block 24 to slide on the welding table of the welding table 1 through the connecting rod 23, so that the plurality of clamping blocks 24 move with the air cushion 26 to detect the side of the broken housing 28.

[0031] As Figure 5 shown, a collection groove 4 is provided on one side of the welding table 1. One side of the collection groove 4 is used to store the broken housing 28, and the other side of the collection groove 4 is used to store the complete housing 29.

[0032] Specifically, the inside of the collection groove 4 is separated by a partition. The broken housing 28 formed after cutting the damaged part of the pump housing is placed on one side inside the collection groove 4, and the complete housing 29 after the steel sheet 37 is welded and repaired to the broken housing 28 is placed on the other side inside the collection groove 4.

[0033] As Figure 6As shown in the figure, a storage bin 2 is provided on one side of the welding table 1. A driving roller 40 is provided on the upper side of the welding table 1 on one side of the storage bin 2. The steel coil 3 is stored in the storage bin 2, and the driving roller 40 is used to convey the steel coil 3 to the cutting device.

[0034] Specifically, open the storage bin 2, place the steel coil 3 in the storage bin 2, pass the steel coil 3 through between the driving rollers 40 and clamp the steel coil 3, and rotate the driving rollers 40 to move the steel coil 3 to the cutting device for cutting.

[0035] As Figure 5 shown in the figure, a fourth pressure roller 31 is provided on the upper side of the welding table 1. A first hydraulic cylinder 5 is fixedly connected inside the welding table 1 on one side of the fourth pressure roller 31. A first pressure roller 6 is provided at the output end of the first hydraulic cylinder 5. Second pressure rollers 7 are provided on both sides of the fourth pressure roller 31 on the upper side of the welding table 1. The fourth pressure roller 31 cooperates with the first pressure roller 6 and the second pressure rollers 7 to press the arc of the steel coil 3 into an arc matching the broken housing 28.

[0036] Specifically, when cutting the steel coil 3, the driving rollers 40 rotate to convey the steel coil 3 to the fourth pressure roller 31, so that the steel coil 3 passes through between the second pressure roller 7 and the fourth pressure roller 31. The steel coil 3 is pressed into a steel sheet 37 with a size and arc matching the broken housing 28 by the second pressure roller 7 and the first pressure roller 6, and then the steel coil 3 is cut by the cutting device to obtain the steel sheet 37 for welding with the broken housing 28.

[0037] As Figure 6 shown in the figure, an electric ring rail 9 is provided on the upper side of the welding table 1. The cutting device is arranged on the lower side of the welding electric ring rail 9, and the electric ring rail 9 is used to drive the cutting device to move.

[0038] Specifically, when cutting the steel coil 3 to form the steel sheet 37, the cutting device can move on the electric ring rail 9, and thus a steel sheet 37 with the same size as the side notch of the broken housing 28 can be cut.

[0039] As Figure 7 shown in the figure, the cutting device includes a lifting frame 10 arranged on the lower side of the electric ring rail 9. The electric ring rail 9 is used to drive the lifting frame 10 to slide. A first motor 11 is fixedly connected to one side inside the lifting frame 10. A threaded rod 12 is fixedly connected to the output end of the first motor 11. A welding block 13 is slidably connected inside the lifting frame 10. A welding gun 14 is provided on one side of the welding block 13. The internal structure of the welding device is the same as that of the cutting device.

[0040] Specifically, when cutting the steel coil 3, start the first motor 11 to rotate the threaded rod 12. The rotation of the threaded rod 12 makes the welding block 13 slide up and down in the lifting frame 10 with the welding gun 14, and the welding gun 14 moves up and down to cut the steel coil 3.

[0041] Embodiment 2: As Figure 8 shown in the figure, compared with Embodiment 1, another implementation manner of the present invention is as follows: A plurality of clamping devices are arranged inside the fourth pressure roller 31. The clamping device includes a fifth cylinder 32 fixedly connected inside the fourth pressure roller 31. One side of the fourth pressure roller 31 is fixedly connected with a fixing plate 35. A clamping plate 33 is rotatably connected inside the fixing plate 35. The clamping plate 33 is rotatably connected with the output end of the fifth cylinder 32. Anti-slip lines are arranged on one side of the clamping plate 33 close to the fourth pressure roller 31. The clamping device clamps the steel sheet 37 through the rotation of the clamping plate 33. A fourth cylinder 30 is fixedly connected above the welding table 1. The output end of the fourth cylinder 30 is fixedly connected with the fourth pressure roller 31. The fourth cylinder 30 is used to move the steel sheet 37 clamped on the fourth pressure roller 31 to the notch of the broken housing 28.

[0042] Specifically, the initial state of the clamping plate 33 is parallel to the top surface of the fourth pressure roller 31 and perpendicular to the side surface of the fourth pressure roller 31. The first pressure roller 6, the second pressure roller 7 and the fourth pressure roller 31 together form the steel coil 3 into a steel sheet 37 with dimensions matching those of the broken housing 28. After the steel coil 3 is cut into the steel sheet 37, the fifth cylinder 32 is started to pull one end of the clamping plate 33, so that the clamping plate 33 rotates through the fixing plate 35, making the clamping plate 33 parallel to the side surface of the fourth pressure roller 31 and perpendicular to the top surface of the fourth pressure roller 31. Then the steel sheet 37 can be clamped and fixed on the side surface of the fourth pressure roller 31 through the clamping plate 33. The fourth cylinder 30 is started to move the steel sheet 37 downward to the notch of the broken housing 28. Moreover, the clamping plates 33 in the clamping device are arranged at intervals, and the clamping blocks 24 in the detection device are also arranged at intervals. The notch of the broken housing 28 can be located more quickly through the interval arrangement of the clamping plate 33 and the clamping block 24.

[0043] Working principle: First, place the broken housing 28 on the welding table under the welding table 1. Through the detection device, make multiple clamping blocks 24 move towards the center with the air cushions 26 and press against the side of the broken housing 28. When the air cushions 26 are completely compressed into the clamping blocks 24 and press against all the buttons 34 through the rubber sleeves 25, it indicates that the side of the broken housing 28 pressed by the air cushions 26 here is intact. When the air cushions 26 are not completely squeezed back into the clamping blocks 24, the air cushions 26 cannot completely press against all the buttons 34, which means there is a notch on the side of the broken housing 28 pressed by the air cushions 26. Then, cut the steel coil 3 into steel sheets 37 that match the notch of the broken housing 28 by the cutting device, feed the steel sheets 37 to the notch of the broken housing 28 by the feeding device, and weld the steel sheets 37 to the broken housing 28 by the welding device; after the air cushions 26 detect the notch of the broken housing 28, start the second hydraulic cylinder 15 to make the clamping blocks 24 move away from the broken housing 28 with the air cushions 26, and then start the third hydraulic cylinder 16 to move the fixed frame 17 towards the center. The fixed frame 17 fixes the broken housing 28 with multiple rollers 18 to prevent the welding device from damaging the air cushions 26 when welding the steel sheets 37 to the broken housing 28; when the air cushions 26 press against, start the second motor 19 to make the first gear 20 rotate. The rotation of the first gear 20 drives the rollers 18 to rotate through the second gear 21. The rotation of the rollers 18 rotates the broken housing 28 to adjust the notch of the broken housing 28, so that the notch of the broken housing 28 rotates to the specified position for cutting the steel sheet 37, enabling the cut steel sheet 37 to move to the notch of the broken housing 28 faster and more accurately. The rotation of the broken housing 28 can also enable the air cushions 26 to comprehensively detect the side of the broken housing 28 and more accurately detect the size of the notch on the side of the broken housing 28; when moving the clamping blocks 24 to detect the broken housing 28, start the second hydraulic cylinder 15 to pull the clamping blocks 24 to slide on the welding table of the welding table 1 through the connecting rod 23, so that multiple clamping blocks 24 move with the air cushions 26 to detect the side of the broken housing 28; The collection tank 4 is separated by a partition. After the damaged part of the pump housing is cut, a broken housing 28 is formed and placed on one side in the collection tank 4. The intact housing 29 after the steel sheet 37 is welded to the broken housing 28 is placed on the other side in the collection tank 4. Open the storage bin 2, place the steel coil 3 in the storage bin 2, pass the steel coil 3 between the driving rollers 40 and clamp the steel coil 3. Rotate the driving rollers 40 to move the steel coil 3 to the cutting device for cutting. When cutting the steel coil 3, the driving rollers 40 rotate to convey the steel coil 3 to the fourth pressing roller 31, so that the steel coil 3 passes through between the second pressing roller 7 and the fourth pressing roller 31. The steel coil 3 is pressed by the second pressing roller 7 and the first pressing roller 6 into a steel sheet 37 with a size and radian matching that of the broken housing 28, and then the steel coil 3 is cut by the cutting device to obtain the steel sheet 37 for welding with the broken housing 28. The cutting device can move on the electric circular track 9, and thus can cut out a steel sheet 37 with the same size as the side notch of the broken housing 28. Start the first motor 11 to rotate the threaded rod 12. The rotation of the threaded rod 12 causes the welding block 13 to slide up and down in the lifting frame 10 with the welding gun 14, and the welding gun 14 moves up and down to cut the steel coil 3. The initial state of the clamping plate 33 is parallel to the top surface of the fourth pressing roller 31 and perpendicular to the side surface of the fourth pressing roller 31, so that the first pressing roller 6, the second pressing roller 7 and the fourth pressing roller 31 together form the steel coil 3 into a steel sheet 37 with a size matching that of the broken housing 28. After the steel coil 3 is cut into the steel sheet 37, start the fifth cylinder 32 to pull one end of the clamping plate 33, so that the clamping plate 33 rotates through the fixing plate 35, making the clamping plate 33 parallel to the side surface of the fourth pressing roller 31 and perpendicular to the top surface of the fourth pressing roller 31. Then the steel sheet 37 can be clamped and fixed on the side surface of the fourth pressing roller 31 through the clamping plate 33. Start the fourth cylinder 30 to move the steel sheet 3 downward to the notch of the broken housing 28. Moreover, the clamping plates 33 in the clamping device are arranged at intervals, and the clamping blocks 24 in the detection device are also arranged at intervals. The arrangement at intervals of the clamping plates 33 and the clamping blocks 24 can more quickly locate the notch of the broken housing 28.
