Not smooth enough, to cause product quality not high, aesthetics is inadequate, and the seam welded is not secured enough.
Summary of the invention
The present invention provides a kind of method of linear guide friction stir spot welding, to solve the problems of the prior art.
To achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of method of linear guide friction stir spot welding, comprising the following steps:
S1, weld preparation stage: two sections of linear guides to be welded are placed on welding cushion block, are clamped respectively using hold assembly
Two sections of linear guides to be welded, so that two sections of linear guide seam alignment to be welded, stirring-head and two sections of linear guides to be welded
Seam contact；
S2, the preparation for welding gap, stirring-head to two sections of linear guide seam azimuthal rotational motions to be welded, and be pressed into two sections to
It welds inside linear guide seam, forms gap to be welded；
S3, fusion weld are merged and are stirred when stirring-head moves to the predetermined depth in two sections of linear guide seams to be welded
Make its fusion weld；
S4, forging and stamping, after fusion weld junction to two sections of linear guide same levels to be welded, stirring-head stops rotating, stirring
Head keeps forging and stamping in fusion weld junction, then again removes stirring-head from two sections of linear guides to be welded, completes welding.
Further, the pretreatment of two sections of linear guides to be welded, two sections of straight lines to be welded are carried out before the step S1
Guide rail, which is placed in clear water, impregnates 1-2h, then is placed in drying in oven.
Further, it when two sections of linear guides to be welded pre-process, places it in and dries 2- in 50-80 DEG C of baking oven
4h, then natural cooling.
Further, in the step S3, predetermined depth is the ten of two sections of linear guide thickness average value to be welded
/ mono-.
Further, in the step S4, forge time of the stirring-head in fusion weld junction is 0.2-1s.
Further, in the step S4, forge time of the stirring-head in fusion weld junction is 0.5-0.8s.
Compared with prior art, the invention has the following advantages:
Fusion weld junction is refined and is recrystallized, the microstructure of solder joint improved, to improve by the method that the present invention uses
The planarization and fastness of solder joint.
Specific embodiment
Below with reference to embodiment, the present invention will be further explained.
A kind of method of linear guide friction stir spot welding, comprising the following steps:
S1, weld preparation stage: two sections of linear guides to be welded are placed on welding cushion block, are clamped respectively using hold assembly
