Embodiment Construction

[0034] In order to better explain the present invention and facilitate understanding, the technical solutions and effects of the present invention will be described in detail below through specific implementation manners in conjunction with the accompanying drawings.

[0035] Such as Figure 3-12 As shown, a dovetail indexing and self-centering device based on the radial boring of special-shaped rings, including a dovetail indexing mechanism, an automatic centering clamping mechanism, a tool setting mechanism and a pressing mechanism;

[0036]The dovetail indexing mechanism includes a base 1, a turntable 2, a screw nut 5, an indexing screw 6, a sleeve 11, and a handwheel assembly 12. The base 1 is a dovetail die, and the center of the base 1 has an arc-shaped dovetail groove. The track and the turntable 2 are dovetail punches, and there is an arc-shaped dovetail boss at the bottom, which forms an arc-shaped slide rail pair with the base 1. In order to reduce the friction durin...

Abstract

The invention relates to a dovetail type indexing and self-centering device based on radial boring of a special-shaped ring member. The device comprises a dovetail type stepless indexing mechanism, anautomatic centering and clamping mechanism, a tool setting mechanism and a pressing mechanism; the automatic centering clamping mechanism and the pressing mechanism are used for positioning and clamping a part. The dovetail type indexing mechanism comprises a base, a rotary disc, a lead screw nut, an indexing lead screw, a sleeve and a hand wheel assembly; the base is a dovetail type female die,the rotary disc is a dovetail type male die, the base and the rotary disc form an arc-shaped sliding rail pair, the rotary disc rotates on the base through the indexing lead screw, and the rotating angle is controlled through a positioning plug pin assembly and an indexing hole in the base. According to the invention, the machining problem of the special-shaped ring member is solved, the part position and size precision requirements are met, and the working efficiency is improved; meanwhile, the defect that the indexing center must be located at the arc center during large-diameter indexing isovercome, the size of the corresponding tool is reduced, the manufacturing cost of the tool is reduced, the manufacturing period of the tool is shortened, and the tool has very high reference significance for similar parts and has very good generalization performance.

Description

technical field [0001] The invention belongs to the technical field of special-shaped parts processing, and in particular relates to a dovetail indexing and self-centering device based on the radial boring of special-shaped ring parts. Background technique [0002] As an important part of the aero-engine casing, the load-bearing ring is composed of 18 special-shaped rings. The structure of the ring is complex and has strict requirements for size and position accuracy. In particular, there are two centripetal bosses on its outer circle, and each boss has three mounting holes perpendicular to the slope. The processing of the slope of the boss and the mounting holes is the key and difficult point of processing special-shaped rings. The structure of the ring is complex, and it is necessary to choose a reasonable positioning and pressing datum to ensure the symmetry requirements of the center holes of the two bosses to the datum. Secondly, the two centripetal bosses form a certai...
