Abstract

The invention discloses a fixture mechanism for creep feed grinding of tenon teeth of a turbine blade. According to the fixture mechanism, a supporting block, a blade body locating block, a side locating block and an axial locating pin are all locating points, are fixed to a main body and are used for locating the bottom face, the side face and the axial direction of the blade; a pressing rod is connected to a cover plate through a pin shaft; a front pressing head and a rear pressing head are connected to the two ends of the pressing rod through pin shafts; the cover plate, the pressing rod, the front pressing head and the rear pressing head form a whole and are arranged on the main body; a front pressing rod and a rear pressing rod are connected with a pressing rod body through pin shafts; a side pressing head is connected with the front pressing rod, a tail pressing head is connected with the rear pressing rod, and a side pressing plate assembly of a lever structure is formed; a leftguide plate and a right guide plate are fixed into grooves in the front ends of two bosses of the main body respectively; and a rapid locating clamping groove is formed in the bottom end of the mainbody and is used for being connected with a machining tool. The tool achieves a very good effect through on-site application. The fixture structure has the advantages of clamping convenience, accuracyand stability, thereby having important significance in optimizing and improving a process route.

Description

technical field [0001] The invention relates to the technical field of disassembly of disc parts, in particular to a fixture mechanism for slow-feeding grinding teeth of turbine blades. Background technique [0002] In the manufacturing process of aero-engine turbine blades, due to the complex profile, small shape and low processing pass rate, it has always been a difficult problem in engine manufacturing technology. As the first manufacturing process, tenon tooth processing is particularly important and difficult. It must be processed by a stable and reliable special fixture. The quality of the fixture structure directly affects the subsequent manufacturing process and pass rate of the entire blade. Due to the difficulty in positioning and clamping the fixture during the slow-feed grinding tenon teeth processing, it is very difficult to realize the structure. However, the traditional structure has the problems of inaccurate positioning, weak compression, and difficult insta...
