[0022] In the utility model, the plug-in assembly includes lock hole one 16, the lock hole one 16 is arranged on the both sides of support frame body 18, the both sides of support frame body 18 are all equipped with lock hole two 17, one side of carriage 10 is fixed with two electromagnetic locks 15 by bolt, the electromagnetic lock 15 is located in support frame body 18, and the electromagnetic lock 15 is inserted with lock hole one 16, before starting cylinder 5 to elongate, electromagnetic lock 15 is started, so that electromagnetic lock 15 is separated from lock hole one 16, when carriage 10 moves upwards to the adhesion of oil tank upper assembly 2 and upper locating seat one 1 and upper locating seat two 11, make electromagnetic lock 15 inserted into lock hole two 17 to fix carriage 10, can avoid the downward movement of carriage 10, and can reduce the force suffered by cylinder 5, improve the service life of cylinder 5;

[0023] In particular, the lifting assembly includes two front ejector plates 7, both of which are bolted to one side of the lower frame 6. Two rear ejector plates 14 are bolted to the other side of the lower frame 6. Alternating grooves 19 are provided at the four corners of the slide 10 to allow the front ejector plates 7 and rear ejector plates 14 to be positioned. The two front ejector plates 7 and two rear ejector plates 14 are evenly and symmetrically distributed on both sides of the lower frame 6. After the upper oil tank assembly 2 and the lower oil tank assembly 3 are welded together to form the oil tank, the electromagnetic lock 1... 5 disengages from lock hole 17. At this time, cylinder 5 retracts, causing slide 10 to move downwards, allowing the front ejector plate 7 and rear ejector plate 14 to pass through the clearance groove 19 on slide 10. When slide 10 moves downwards to the point where the rear ejector plate 14 contacts the oil tank, slide 10 continues to move downwards, causing the rear ejector plate 14 to lift the oil tank. Simultaneously, under the action of gravity, the inclined surface of the oil tank will tilt towards the front ejector plate 7, causing the front ejector plate 7 to contact the oil tank, thus allowing the front ejector plate 7 and rear ejector plate 14 to... The oil tank is lifted up, causing it to detach from the lower positioning seat 1 4 and the lower positioning seat 2 13, creating a gap between the oil tank and the lower positioning seat 1 4 and the lower positioning seat 2 13. This facilitates the removal of the welded oil tank by the workers, improving the ease of use of the welding positioning device. Support ribs 20 are bolted to one side of the two front stripping templates 7 and the rear stripping template 14. The support ribs 20 can strengthen the front stripping templates 7 and the rear stripping template 14, thus preventing deformation of the oil tank supported by the front stripping templates 7 and the rear stripping template 14. Two sliding sleeves 8 are bolted to the other two sides of the lower frame 6. Two sliding rods 9 are bolted to the bottom of the slide 10 on both sides, and the sliding rods 9 pass through the sliding sleeves 8. When the slide 10 moves up and down, it will drive the sliding rods 9 to move within the sliding sleeves 8, thus guiding the movement of the slide 10. The lower oil tank component 3 is placed inside the lower positioning seat 1 4 and the lower positioning seat 2 13, and the upper oil tank component 2 is placed on top of the lower oil tank component 3.

[0024] The working principle of this utility model is as follows: In use, the lower fuel tank component 3 is placed inside the lower positioning seat 1 4 and the lower positioning seat 2 13, and then the upper fuel tank component 2 is placed on the lower fuel tank component 3. Subsequently, the electromagnetic lock 15 is activated to disengage from the lock hole 1 16, and then the cylinder 5 is activated to extend. The cylinder 5 pushes the slide 10 to move upward, and the slide 10 drives the lower positioning seat 1 4 and the lower positioning seat 2 13 to move upward, thereby causing the lower fuel tank component 3 and the upper fuel tank component 2 to move upward, so that the upper fuel tank component 2 enters the upper positioning position. Inside the first seat 1 and the second upper positioning seat 11, the upper component 2 of the fuel tank is brought into contact with the first and second upper positioning seats 11. At this time, under the action of the first and second upper positioning seats 11, the upper component 2 of the fuel tank will be corrected, so that the upper component 2 of the fuel tank is aligned with the lower component 3 of the fuel tank, thereby positioning the upper component 2 and the lower component 3 of the fuel tank and preventing misalignment, thus improving the welding quality of the fuel tank. At this time, the electromagnetic lock 15 is inserted into the second lock hole 17 to position the slide 1. Fixing the slide 10 at position 0 prevents it from moving downwards and reduces the force on the cylinder 5, thus extending its service life. After the upper assembly 2 and lower assembly 3 of the oil tank are welded together to form the oil tank, the electromagnetic lock 15 is disengaged from the second lock hole 17. At this time, the cylinder 5 is activated to retract, causing the slide 10 to move downwards, allowing the front ejector plate 7 and rear ejector plate 14 to pass through the clearance groove 19 on the slide 10. When the slide 10 moves downwards and the rear ejector plate 14 contacts the oil tank, the slide 10... As it continues to move downwards, the rear ejector plate 14 lifts the oil tank. Simultaneously, under the influence of gravity, the inclined surface of the oil tank tilts towards the front ejector plate 7, causing the front ejector plate 7 to contact the oil tank. This, in turn, lifts the oil tank from the lower positioning seat 1 4 and the lower positioning seat 2 13, creating a gap between the oil tank and the lower positioning seat 1 4 and the lower positioning seat 2 13. This facilitates the removal of the welded oil tank by the workers, improving the ease of use of the welding positioning device.
