Abstract

The invention discloses a fixture mechanism for nozzle turning, and belongs to the technical field of fixtures. The fixture mechanism for nozzle turning comprises a chassis, a swing frame mechanism and an automatic centering structure; the swing frame mechanism comprises a left support and a right support which are fixedly arranged on the chassis, a swing frame is rotationally arranged between the left support and the right support, and the swing frame moves along arc-shaped rails of the left support and the right support; and the automatic centering structure comprises a positioning shaft, an angle limiting mechanism, a side face clamping mechanism and a horizontal limiting mechanism, the positioning shaft is arranged on the swing frame, the angle limiting mechanism is arranged on the arc-shaped rails, and the side face clamping mechanism and the horizontal limiting mechanism are both arranged on the chassis. The fixture mechanism for nozzle turning is suitable for turning the ends of nozzles with different angles, precise positioning and clamping of the nozzles can be achieved, the machining accuracy of the ends is guaranteed, and the machining qualification rate is increased.

Description

technical field [0001] The invention relates to the field of fixture technology, in particular to a fixture mechanism for nozzle turning. Background technique [0002] In the manufacturing process of aero-engine turbine blades, due to the different angles of the nozzle structure, small shape, and low processing pass rate, it has always been a difficult problem in engine manufacturing technology. It must be processed by a stable and reliable special fixture, and the quality of the fixture structure directly affects Subsequent manufacturing process and pass rate of nozzles. Due to the different angles of the ends of the nozzle parts, a large number of fixtures need to be designed to ensure the processing requirements of the parts. It is difficult to position and clamp the fixtures during processing, and it is very difficult to realize the structure. However, the traditional structure has inaccurate positioning, weak compression, and installation problems. Find the hard proble...
