Embodiment Construction

[0034] This embodiment is an internal support tooling used for turning the welding groove of the port of a thin-walled cylinder with a diameter of φ750×δ3×1450. The part is a thin-walled cylindrical part. The cylinder adopts spinning forming technology. The inner diameter of the cylinder is Ф744, the wall thickness of the cylinder is 3mm, and the total length of the cylinder is 1450mm. The design drawings require that the welding groove be machined at the end of the cylinder, the slope of the welding groove is required to be 45°, and the size of the blunt side of the groove is

[0035] The turning inner brace for the welding groove of the port of the thin-walled cylinder includes a mandrel disk 1 , a large nut 3 , a transmission rod 9 , a push rod 10 , a top block 11 and a sliding sleeve 7 . Wherein: the large nut 3 is set on the external threaded surface of the upper end of the mandrel disc, the sliding sleeve 7 is set on the outer circular surface of the lower end of the m...

Abstract

The invention discloses a turning inner brace fixture for the end opening of a cylinder. A big nut is arranged on the external thread surface at the upper end of a disk column of a central spindle disk in a sleeving mode. A sliding sleeve is arranged on the external thread surface at the lower end of the disk column of the central spindle disk in a sleeving mode. Two end face bearings are arranged in a bearing groove of the big nut and a bearing groove of the sliding sleeve in a sleeved mode correspondingly. A disk cover is arranged on the outer circumferential surface of the big nut in a sleeving mode and is fixed to the upper surface of a disk cover mounting table of the sliding sleeve. A plurality of connecting blocks are fixed to the outer edge of the sliding sleeve and are connected with all ejection blocks through a plurality of ejection rods and a plurality of drive rods correspondingly. The turning inner brace fixture has the characteristics that shape correcting and circle supporting of the spinning cylinder can be achieved, fixture errors are small, and product stress is even in the using process; the rigidity and machining precision of the end opening portion of a thin walled cylinder can be effectively improved, and the turning technical problem of the end opening portion of the thin walled cylinder is solved; and meanwhile, manual operation strength is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an inner support tool for turning the end of a thin-walled cylinder. technical background [0002] A cylinder part is one of the important parts of a solid rocket motor shell, and is finally welded and assembled with other parts. The solid rocket motor has strict requirements on the welding quality between the cylinders, and the welding of the end of the cylinder Groove processing accuracy has a great influence on welding quality. [0003] The cylindrical part is a thin-walled cylindrical part. The cylinder adopts spinning forming technology. The inner diameter of the cylinder is Ф744, the wall thickness of the cylinder is 3mm, and the total length of the cylinder is 1450mm. The design drawings require that the welding groove be machined at the end of the cylinder, the slope of the welding groove is required to be 45°, and the size of the blunt side of the groove is [00...
