[0006] Reference Figures 1-4 The aforementioned anti-tipping welding device for a submersible electric pump unit is characterized by comprising a fixed base 1 and a rodless cylinder 2 inserted into the middle of the left side of the upper surface of the fixed base 1. A clamping device 3 is connected to the middle of the upper surface of the cylinder body of the rodless cylinder 2. A supporting device 4 is connected to the middle of the upper surface of the fixed base 1. A fixing clamp 5 is connected to the middle of the right side of the upper surface of the fixed base 1. A fixing bracket 6 is connected to the middle of the rear edge of the upper surface of the fixed base 1. A welding host 7 is inserted through the middle of the front of the upper surface of the fixing bracket 6.
[0007] In use, first place the submersible electric pump on the support device 4, and at the same time, make the right end of the submersible electric pump contact with the fixed clamp 5. Then, start the rodless cylinder 2 to make the cylinder body of the rodless cylinder 2 slide in the fixed base 1. At the same time, the cylinder body of the rodless cylinder 2 drives the clamping device 3 to move to the right. Then, clamp the clamping device 3 on the left end of the submersible electric pump to clamp the submersible electric pump. Finally, start the welding host 7 on the fixed bracket 6 to perform welding.
[0008] When welding the submersible pump at different positions, the submersible pump can be rotated between the clamping device 3 and the fixed fixture 5.
[0009] The structure and electrical connection structure of the welding host 7 are existing technologies, and the technical effects to be achieved by using existing technologies can be achieved by this utility model.
[0010] Furthermore, the clamping device 3 includes a column 3-1, a hydraulic cylinder 3-2, a clamping plate 3-3, and a rubber pad 3-4. The hydraulic cylinder 3-2 is connected to the middle of the outer surface of the column 3-1. The clamping plate 3-3 is rotatably connected to the center of the outer surface of the telescopic end of the hydraulic cylinder 3-2. The rubber pad 3-4 is connected to the center of the inner surface of the clamping plate 3-3. The telescopic end of the hydraulic cylinder 3-2 is inserted through the side surface of the column 3-1. The lower surface of the column 3-1 is connected to the upper surface of the cylinder body of the rodless cylinder 2.
[0011] In use, start the rodless cylinder 2 to move the cylinder body of the rodless cylinder 2 to the right, causing the column 3-1 to move. At this time, the telescopic end of the oil cylinder 3-2 is extended. Then, the chuck 3-3 contacts and clamps the left end of the submersible pump. At the same time, the rubber pad 3-4 can increase the friction between the chuck 3-3 and the submersible pump. When welding different positions, rotate the submersible pump to make the chuck 3-3 rotate on the telescopic end of the oil cylinder 3-2. Finally, when replacing the submersible pump, start the oil cylinder 3-2 to retract the telescopic end for replacement.
[0012] Furthermore, the support device 4 includes a column 4-1, a groove 4-2, a roller 4-3, and a plug 4-4. The upper surface of the column 4-1 is provided with a groove 4-2 in the middle. The roller 4-3 is symmetrically inserted into the middle of the upper edge of the inner side surface of the groove 4-2. Each of the four corners of the lower surface of the column 4-1 is connected to a plug 4-4. The plug 4-4 is inserted into the upper surface of the fixed base 1. The position and height of the column 4-1 are matched with the position and height of the column 3-1. The upper surface of the fixed base 1 is provided with slots evenly distributed horizontally to cooperate with the plug 4-4.
[0013] In use, first place the column 4-1 on the upper surface of the fixed base 1, then insert the plug 4-4 into the appropriate socket, then place the submersible electric pump on the upper surface of the column 4-1 and insert it into the groove 4-2, while the side surface of the submersible electric pump contacts the roller 4-3, and finally rotate the roller 4-3 to reduce friction when rotating the submersible electric pump.
[0014] Furthermore, the fixing clamp 5 includes a vertical plate 5-1, a rotating shaft 5-2, a turntable 5-3, and a rubber disc 5-4. The rotating shaft 5-2 is rotatably inserted into the center above the inner surface of the vertical plate 5-1. The turntable 5-3 is connected to the center of the outer surface of the rotating shaft 5-2. The rubber disc 5-4 is connected to the center of the outer surface of the turntable 5-3. The position of the turntable 5-3 cooperates with the position of the clamping disc 3-3. The upper surface of the fixing base 1 is connected to the lower surface of the vertical plate 5-1.
[0015] When in use, first place the right end of the submersible pump on the side surface of the turntable 5-3, and at the same time, the rubber disc 5-4 increases the friction between the submersible pump and the turntable 5-3. Finally, when rotating the submersible pump, the turntable 5-3 drives the rotating shaft 5-2 to rotate within the vertical plate 5-1.
