The second component 300 is a cylindrical plate member having a cross-shaped cross section, and is provided in two. It is understood that the first component 200 may be formed by two separate plates that are crossed with each other, or may be an integral part.

The third component part 400 is a third plate and is provided in two. Two cross-shaped through holes are formed in the first plate at intervals, first ends of the two second parts 300 penetrate through the corresponding cross-shaped through holes respectively and extend out of the lower surface of the first part 200 for a certain distance, and at the moment, the extending portions of the second parts 300 are matched with the bottom surface of the first part 200 to form first welding spot positions.

In addition, the cooperation between the second component part 300 and the upper surface of the first component part 200 forms a second weld location that is proximate to the medial portion of the second component part 300.

When the third magnetic element is a magnet, the first pressing plate 20 is made of a magnetically attractable material, so that the first pressing plate 20 can be directly attracted and fixed by the third magnetic element after being placed on the positioning bottom plate 10, the first component 200 is compressed simply, and the first pressing plate 20 is convenient and quick to mount and dismount.

With reference to fig. 2, fig. 5 and fig. 6, on the basis of any of the above embodiments, the first limiting assembly 30 includes a guiding plate 31, the guiding plate 31 is configured to be mounted on the positioning base plate 10, and the guiding plate 31 is provided with a second space-avoiding portion 311 opposite to the first component 200, and the second space-avoiding portion 311 is configured to allow the second component 300 to pass through to be assembled with the first component 200.

When the second component 300 and the first component 200 are assembled in actual machining, the guide plate 31 is firstly installed and fixed on the positioning base plate 10, then the second component 300 is inserted into the second clearance space 311 until the first end of the second component 300 and the cross-shaped through hole penetrating through the first component 200 complete the assembly of the second component 300 and the first component 200, and in the process, the guide plate 31 plays a role in guiding and limiting the second component 300, so that the second component 300 is accurately inserted into the first component 200.
