[0003] In actual operation, the subframe assembly is relatively complicated. In order to improve the welding quality, it is usually necessary to use a positioning device for positioning and fixing during welding. However, there are slight differences in the external dimensions of subframes of different brands and styles.

[0004] Under existing technologies, different positioning devices are usually used to fix different subframes during welding. Although this processing method can meet the welding requirements of different subframes, the development and procurement costs of using multiple positioning devices are high, which to a certain extent increases the processing cost of subframe welding.

[0005] The prior art discloses a patent with publication number CN219336585U, which includes a base plate, an upper surface of the base plate is provided with an adjusting device, and a front crossbeam, a rear crossbeam and two longitudinal beams are placed on the upper surface of the base plate with the aid of the adjusting device.
