Embodiment Construction
[0046] The technical solutions of the present invention will be further described in detail below through specific examples.
[0047] The source switch assembly is composed of source switch depleted uranium parts and a supporting plate. Due to the deformation problem of the depleted uranium workpiece, the workpiece is assembled and processed in two pieces, which increases the difficulty of ensuring the dimensional accuracy. In order to ensure the processing accuracy of the workpiece, the product processing is designed through process tests Technology, design a source switch depleted uranium shield assembly processing method of the present invention. The completed source switch assembly has stable technology, the position of the eccentric hole and the precision of the inner hole meet the technical requirements, and all indicators meet the requirements of the drawing design.

Abstract
The invention belongs to the field of metal uranium material special structural products and a manufacturing technology and process of the products, and particularly relates to a machining method of a source switch depleted-uranium shield assembly. The machining method comprises following steps of structure determining and component machining. Machining of a depleted-uranium component comprises the steps of rough turning of the appearance of a depleted-uranium component; removing graphite left on the position of a depleted-uranium eccentric hole, and roughly boring the depleted-uranium eccentric hole; releasing residual stress inside the depleted-uranium component; carrying out finish turning on the appearance of the depleted-uranium component until the outer diameter size and the total height reaches the set size; and carrying out fine boring on the lower portion of the depleted-uranium eccentric hole. Machining of a supporting plate comprises the steps of enabling screws to penetrate bolt holes in the depleted-uranium component and the supporting plate to enable the supporting plate to be mounted on the depleted-uranium component; clamping the height center position of the first layer cylinder of the depleted-uranium component through a three-jaw chuck and carrying out centering; jig manufacturing, and machining out machining standard transferring on the machining center.
Description
technical field [0001] The invention belongs to the field of metal uranium material special structure products and its manufacturing technology and manufacturing process, and specifically relates to a processing method for a source switch depleted uranium shielding body assembly. Background technique [0002] Gamma Knife is a treatment device for tumors with cobalt 60 as the source. The Gamma Star B5 product is the core component of Gamma Knife equipment.
