Description

Technical Field

[0001] The present invention belongs to the technical field of fuel tank partition welding, and in particular relates to a welding device for a fuel tank partition of an automobile. Background Art

[0002] A partition is usually installed in the oil tank. The function of the partition is to separate the oil return area from the oil suction area of ​​the pump, increase the oil circulation path, reduce the oil circulation speed, and facilitate cooling and heat dissipation, bubble precipitation and impurity precipitation.

[0003] When welding and fixing the partition to the oil tank, the ordinary clamping mechanism can only perform a single clamping, but the welding conditions of the partitions are different. Faced with partitions with different welding requirements, a single fixing structure cannot meet the fixing effect. The fixing mechanism needs to be replaced, which reduces work efficiency. When the partition is welded, splashing welding slag will be generated. The welding slag adheres to the partition and the oil tank, causing corrosion to the oil tank and the partition, affecting the service life of the partition and the oil tank. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the problems in the related technology, the present invention proposes a welding device for an automobile fuel tank partition, which is equipped with a horizontal moving block that moves along a horizontal screw rod to adjust the clamping position of the clamping fixing plate, and the rotating rod rotates to adjust the fixing angle and fixing position of the clamping fixing plate on the fuel tank partition, so that the partition clamping assembly can clamp and fix when performing welding work at different angles and positions on the fuel tank partition, without the need to replace the fixture, thereby improving work efficiency. The partition baffle protects the fuel tank baffle, and the fuel tank baffle protects the fuel tank to prevent welding slag from splashing onto the fuel tank partition and the fuel tank during welding, reducing the erosion of the fuel tank and the partition by the welding slag, and improving the welding quality. It solves the technical problem that when facing partitions with different welding requirements, a single fixing structure cannot meet the fixing effect, and the fixing mechanism needs to be replaced, which reduces work efficiency. When the partition is welded, splashing welding slag will be generated, and the welding slag adheres to the partition and the fuel tank, causing corrosion to the fuel tank and the partition, thereby affecting the service life of the partition and the fuel tank.

The automobile fuel tank partition welding device according to claim 5, characterized in that: The lifting screw (401) is movably installed in the baffle installation groove, the lifting motor (402) is fixedly installed on the top of the clamping fixed plate (311), the transmission shaft of the lifting motor (402) passes through the clamping fixed plate (311) and is fixedly installed with the lifting screw (401), the partition baffle (403) is movably installed in the baffle installation groove, the partition baffle (403) is sleeved with the lifting screw (401), and the partition baffle ( A plurality of arc-shaped racks (405) are fixedly mounted on a side of the oil tank baffle (403) away from the clamping fixed plate (311), a plurality of arc-shaped connecting blocks (406) are fixedly mounted on the top of the oil tank baffle (404), the arc-shaped connecting blocks (406) and the arc-shaped racks (405) are movably mounted, the rotating gear (407) is fixedly mounted on the top of the arc-shaped connecting blocks (406), and the rotating gear (407) is engaged with the arc-shaped racks (405).

7. The automobile fuel tank partition welding device according to claim 6, characterized in that: The rotating connecting rod (408) is arranged above the oil tank partition, the rotating connecting rod (408) is fixedly installed with the rotating gear (407), the rotating motor (410) is fixedly installed on the top of the clamping fixing plate (311), the rotating connecting rod (408) is movably installed with the connecting belt (409), and the connecting belt (409) is movably installed with the rotating motor (410).

8. The automobile fuel tank partition welding device according to claim 7, characterized in that: The rotating motors (410) rotate in the same direction. When the rotating motor (410) on one side drives the rotating gear (407) on one side to rotate, the angle between the partition baffle (403) on one side and the oil tank baffle (404) increases. The rotating motor (410) on the other side drives the rotating gear (407) on the other side to rotate, the angle between the partition baffle (403) on the other side and the oil tank baffle (404) decreases, and the angles between the two are always complementary.
