Abstract

The invention discloses a positioning type water flow clamp for turbine blades. A vertical plate (5) and an eccentric wheel support (12) are installed on a bottom plate (6), a positioning part is formed by combining a tenon tooth pressing block (1), a tenon tooth positioning block (2) and a side face positioning pin (3), the tenon tooth pressing block (1) and the tenon tooth positioning block (2) form a tenon tooth space, the side face positioning pin (3) fixes the end face of a tenon, and the three components of the positioning part are fixed to the vertical plate (5) through screws; the left side of a transverse center channel of a telescopic rod (9) is plugged through a plug (10), and the transverse center channel of the telescopic rod (9) is communicated with a water inlet channel (14) in the vertical direction inside the telescopic rod (9); the right end of the telescopic rod (9) is embedded into the vertical plate (5) through a guiding pin (8) in a clearance fit mode; a compression spring (13) is arranged between the telescopic rod (9) and the vertical plate (5), and a seal gasket (4) is arranged between the telescopic rod (9) and the tenon tooth pressing block (1); the left end of the plug (10) corresponds to an eccentric wheel (11). The positioning type water flow clamp can restrain damming, and is good in seal performance, easy to operate and stable in performance.

Description

technical field [0001] The invention belongs to the field of tooling design in mechanical processing, and in particular relates to a positioning type turbine blade water flow fixture. Background technique [0002] At present, in the water flow measurement process of hollow turbine blades, the water flow fixture used is a simple rubber wrapping form with a rough structure. The entire fixture is composed of a piece of rubber, and the middle is roughly clamped by the tenon of the blade. Due to the limitations of the structure of this type of fixture, the phenomenon of interception and water seepage often occurs in the process of measuring water flow. process requirements. Contents of the invention [0003] The purpose of the present invention is to provide a positioning type turbine blade water flow clamp, which can inhibit interception, has good sealing performance, simple operation and stable performance. The fixture is designed and manufactured with the concept of precis...
