Beschreibung
Zusammenfassung:	The invention relates to the field of mechanical fasteners, in particular to a bolt connecting assembly and a machining process thereof.The bolt connecting assembly comprises a screw and a lining arranged outside the screw in a sleeving mode, the lining comprises an inner pipe sleeve and an outer pipe sleeve, the inner pipe sleeve is internally connected into the outer pipe sleeve, and a first flange is arranged on the periphery of an upper pipe opening of the outer pipe sleeve; a locking edge is arranged on the inner side of the upper portion of the outer pipe sleeve, a wedge-shaped opening is formed in the upper end of the inner pipe sleeve on the lower side of the locking edge, a groove used for containing the locking edge is formed in the peripheral wall of the upper portion of the screw, and a second flange is arranged on the periphery of a lower pipe opening of the inner pipe sleeve. The bushing is divided into the inner pipe sleeve and the outer pipe sleeve, when the screw rod is screwed, the distance
