摘要： In a friction stir welding method of manufacturing a piston for a variable capacity swash plate type compressor, the welder is shifted from the welded portions to a predetermined position while maintaining contact between the welder and one of the piston members. After finishing the friction stir welding, a hole is not formed in the welded portions of the piston members to improve durability of the welded portions. The piston members are elastically supported by support rollers to align the central axial lines of the piston members with the axial line of the chuck, even though the diameters of the piston members differ.

摘要： The present invention relates to a manufacturing method of a piston for a swash plate type compressor with variable capacity. More particularly, the present invention relates to a manufacturing method of a piston for a swash plate type compressor with variable capacity, which manufacture a piston from two piston members through friction stir welding without forming any hole in welded portions of the piston members, thereby improving durability of the welded portions and easily manufacturing a piston regardless of the size of the outer diameter of the piston members. A method of the present invention includes the step of; temporarily coupling the first and second piston members formed respectively; loading the first and second piston members on the support rollers lifted and lowered elastically by elastic spring; position controlling of the central axis line of the first and second piston members to that of the first and second supporting parts; rotatably supporting the first and second piston members on the first and second supporting parts; friction stir welding by rotating the rotation supporting means after a welding means is inserted to a welding portion with rotation; moving the welding means inserted to the welded poison to the predetermined position; and separating the welding means from the welded portion.

摘要： Disclosed is a friction stir welding apparatus of a piston for a swash plate type compressor with variable capacity, which integrally bonds two piston members of round section with each other through friction stir welding without forming any hole in welded portions of the piston members, thereby improving durability of the welded portions and easily bonding the piston members by size regardless of the size of the outer diameter of the piston members. The friction stir welding apparatus includes: rotation supporting means for rotatably supporting first and second piston members coaxially coupled to each other; a welding means rotatably inserted into welded portions of the first and second piston members supported on the rotation supporting means, for carrying out friction stir welding along the rotation direction of the first and second piston members; support rollers elastically mounted on the lower portions of the piston members to arrange central axis lines of the piston members on central axis lines of the rotation supporting means when the piston members are supported on the rotation supporting means, and to vertically move within a predetermined height (H) range while supporting the piston members; and transferring means for transferring the welding means from the welded portions to a predetermined position after the friction stir welding of the welded portions by means of the welding means.

摘要： A friction stir welding apparatus of a piston for variable capacity swash plate type compressor bonds two pistons through frictions stir welding without forming a hole in welded portions of the piston members. The friction stir welding apparatus includes: A support that rotatably supports coaxially coupled first and second pistons. A welder, rotatably inserted into welded portions of the first and second pistons supported on the support, performs friction stir welding along the rotation direction of the first and second pistons. Support rollers elastically mounted on the lower portions of the pistons have central axis lines of the piston members on central axis lines of the rotation support while the pistons are supported on the support. The rollers vertically move through a predetermined height while supporting the pistons. The welder is transferred from the welded portions to another position after welding of the welded portions.
