In the embodiment, a plurality of mounting holes 313 are arranged on the baffle fixing plate, and the baffle positioning block 303 is fixed on the lower end of the baffle fixing plate 301 by matching with the mounting holes 313 through bolts.

The baffle fixing plate 301 is connected with a driving device, and the driving device can drive the oil pan baffle 2 positioned at the lower end of the baffle fixing plate 301 to move to a preset baffle welding position for cooperation with the oil pan 1.

[0035] In the embodiment, the fixing and pressing of the oil pan 1 are realized through the oil pan positioning mechanism 100 and the oil pan baffle positioning mechanism 300. The oil pan baffle positioning mechanism 300 drives the oil pan baffle positioned at the lower end of the baffle fixing plate 301 through a driving device and moves it to a preset baffle welding position for mating with the oil pan, so that the oil pan baffle can be welded.

[0036] In an embodiment of the present invention, the oil pan positioning mechanism 100 includes a support 101. In the embodiment, two supports 101 are provided and are respectively fixed at both ends of the bottom plate 102. The pressing block driving device 202 is installed on the support 101.

Due to the setting of the nitrogen spring, only a continuous downward force is required. If there is no nitrogen spring, the operator needs to control this positioning to avoid collisions between workpieces caused by sudden falling, which is laborious and unsafe. The setting of the nitrogen spring prevents collisions between workpieces during the clamping process and ensures the quality of the product.

[0044] After welding is completed, only need to open the dead center of the push-pull type quick clamp 304, and the nitrogen spring will drive the oil pan baffle positioning mechanism 300 to slowly rise, saving manpower.

The nitrogen spring can support the oil pan baffle positioning mechanism 300 to prevent falling, ensuring the stability of the positioning mechanism during the entire working process and avoiding potential risks to the staff. The use of the nitrogen spring makes the loading and unloading processes easier, reduces the labor intensity of workers, and improves production efficiency.

[0045] Since the external dimensions of the oil pans in the same series are usually the same, one device can be used to assist in the welding of multiple oil pans in the same series. The difference between different oil pan baffles lies in the shape of the opening through which the oil pump can pass on the baffle. By replacing the baffle positioning blocks with different geometric features through the cooperation of the mounting holes and bolts, the positioning of different baffles can be achieved, enhancing the flexibility and application range of the tooling, such as Figure 6 、 Figure 7As shown, the versatility of the equipment is thus greatly improved, and the production cost is reduced.

[0046] The welding auxiliary equipment for the inner baffle of the oil pan in the embodiment has progress in improving production efficiency, ensuring product quality, reducing production cost, and enhancing safety, and has high practical value.
