Detailed Description
The technical scheme of the invention is further described in detail in the following with the accompanying drawings of the specification.
As shown in fig. 1, fig. 2 and fig. 3, the thin-walled hub type part processing device of the present invention includes a support body 1, a positioning module 2 and a plurality of end face pressing mechanisms 3. The support body 1 is provided with a three-jaw self-centering synchronous clamping structure, namely the support body 1 adopts a three-jaw chuck structure. The support body 1 realizes automatic synchronous positioning and clamping of rotary parts, and meanwhile, a plurality of groups of threaded holes are formed in the end face of the support body 1 (on the end face of a three-jaw self-centering synchronous clamping structure), the plurality of groups of threaded holes are distributed from inside to outside along the radial direction, the plurality of threaded holes in each group of threaded holes are uniformly distributed along the circumferential direction, and the plurality of groups of threaded holes are used for installing and arranging the end face pressing mechanism 3. The positioning module 2 is of an annular structure, an annular groove (outer spigot positioning) is arranged on the inner periphery of the positioning module 2 or an annular boss (inner spigot positioning) is arranged on the end face of the positioning module 2, namely the positioning module 2 is divided into two types of inner spigot positioning and outer spigot positioning according to the structure and the size of the thin-wall hub part to be processed. The positioning module 2 is fixed in the central hole of the support body 1, and the end face pressing mechanisms 3 are respectively fixed on the end faces of the support body 1. The end face pressing mechanism 3 adopts the existing clamping mechanism. The end face pressing mechanism 3 comprises an auxiliary support, a movable pressing plate, a bolt, a nut, an elastic washer and the like and is composed of standard clamp elements.
