By arranging and setting a plurality of positioning holes, which correspond to the front and back sides of different engines and the support parts of different structures, the optional installation positions of the support columns are increased, which can adapt to the installation of engines of different sizes, and has good versatility.

Preferably, the step is a semi-circular step, which is further adapted to the circular step surface of the engine.

Preferably, the groove is a circular groove, which is further adapted to the cylindrical connecting piece of the engine.

Preferably, the diameter of the groove is 25mm, and the depth of the groove is 5-10mm, which further improves the connection stability of the cylindrical connecting piece of the engine.

Preferably, the diameter of the boss is 70mm, and the depth of the step is 18mm, which further improves the connection stability of the step surface of the engine.

Preferably, the diameters of the first support column, the second support column, the third support column and the fourth support column are respectively 40mm, 50mm, 50mm and 35mm, which further improves the stress stability of different parts of the engine.

Beneficial effects of the present invention:

The tray support column of the present invention has four different structures: a flat head support column, a stepped surface support column, a support column with a positioning pin, and a support column with a groove. Each time the body is supported, a support column with no structure is selected according to the structure of the left and right sides of the engine body. By replacing different support columns, it can meet the needs of body turnover and model conversion in assembly line production, and effectively solve the need to replace different transfer trays for body turnover and model conversion.
