[0031] The gravity component 30 and the limiting cavity 220 are provided with relatively positioned assembly openings A, and the gravity component 30 is provided with an operation opening B exposing the limiting cavity 220 .

[0032] The welding fixture of the utility model facilitates the placement of the workpiece to be welded into the limiting cavity 220 through the assembly opening A of the relative position of the gravity component 30 and the limiting cavity 220, and the cylinder 50 is in a state of lifting and supporting the gravity component 30 when the workpiece to be welded is assembled; when the workpiece to be welded is assembled, the cylinder 50 contracts to release the gravity component 30, so that the gravity component 30 is pressed down toward the limiting cavity 220 under the action of gravity, and the workpiece to be welded placed in the limiting cavity 220 is pressed, so as to stably clamp the workpiece to be welded. Among them, the gravity component 30 is supported by multiple groups of linear bearing components 40 at multiple points, which can achieve uniform support for the gravity component 30, avoid deformation of the gravity component 30, and ensure smooth and stable movement of the gravity component 30. Furthermore, through the operation opening B of the gravity component 30 that exposes the limiting cavity 220, it is convenient to perform welding operations on the workpiece to be welded.

[0033] The welding fixing tool of the utility model is particularly suitable for the fixed welding of the shock absorber assembly 60 including the lifting ear 62, the cover plate 63 and the connecting rod 64.
