The embodiment provides a groove body laser welding fixture, which can avoid melting the groove bottom 610 and the pressing plate after welding and avoid scrapping the pressing plate and the product. As shown in fig. 2 and 3, the groove body laser welding fixture comprises a mounting frame mechanism 10, a pressing driving member 20 and a pressing mechanism 30, wherein the pressing driving member 20 is mounted on the mounting frame mechanism 10, and the pressing driving member 20 can output movement along the vertical direction; the pressing mechanism 30 includes a first mounting plate 31 and a first contact assembly 32, the first mounting plate 31 is mounted at the output end of the pressing driving member 20, the first contact assemblies 32 are all mounted at one side of the first mounting plate 31 facing away from the pressing driving member 20, the first contact assemblies 32 that can be driven by the pressing driving member 20 move along the vertical direction, and the first contact assemblies 32 can be in point contact or line contact with the groove bottom 610 of the groove body 600. By arranging the first contact assembly 32 in point contact or line contact with the groove bottom 610, in the laser welding process, the contact of the prior art pressing plate type is achieved to the current point or line contact, so that the contact area between the first contact assembly 32 and the groove bottom 610 is greatly reduced, the groove bottom 610 and the pressing plate are prevented from being fused together after being welded, and the pressing plate and the product are prevented from being scrapped.

Specifically, as shown in fig. 2, the first contact assembly 32 includes a pivot 321 and a roller 322, the pivot 321 includes a connecting rod 3211 and a U-shaped portion 3212, and the connecting rod 3211 is connected to the first mounting plate 31; the rollers 322 are pivotally connected to the U-shaped portion 3212, and the circumferential surfaces of the rollers 322 can abut the groove bottom 610. Through the above arrangement, the roller 322 is in line contact with the groove bottom 610, the contact area is small, and when the roller 322 presses down the driving element 20, the micro-movement of the groove bottom 610 can convert the hard friction into the rolling friction, thereby preventing the first contact component 32 from generating scratches on the outer surface of the groove bottom 610.

In this embodiment, as shown in fig. 3, two pressing driving members 20 are disposed along the length direction of the slot 600, so as to ensure the uniformity of the stress of the plurality of first contact assemblies 32.
