Device for locating female die of fan blade

Abstract

The invention discloses a device for locating a female die of a fan blade, wherein the device comprises two fixing blocks respectively pre-embedded in a flange edge of an upper die and in a flange edge of a lower die, internal and external studs respectively in threaded connection into the two fixing blocks, a concave block installed on one of the two fixing blocks, and a convex block installed on the other of the two fixing blocks, and when the upper die and the lower die are assembled, the convex block is inserted into the concave block. According to an exemplary embodiment of the invention, as the concave block and the convex block respectively pass through small eccentric thread holes and are connected with the fixing blocks through fasteners, and the small thread holes are designed in an eccentric manner, the relative horizontal position between the concave block and the fixing block, and between the convex block and the fixing block can be freely regulated within a scope, as a result, the displacement of the upper die and the lower die can be within a controllable scope during die assembly.

Description

technical field [0001] The invention relates to a positioning device for a female mold of a fan blade, more specifically, to a positioning device for a female mold of a fan blade which is convenient for adjusting the relative positions of the mold clamping seams. Background technique [0002] The female mold of the fan blade includes an upper mold and a lower mold. The lower mold is fixed on the ground, and the upper mold realizes mold closing and mold opening operations through a turning system. Since the female mold made of composite materials has the characteristics of thermal expansion and cold contraction deformation, the upper mold is deformed by gravity during the process of repeated mold opening and closing, so that the female mold will be left and right after repeated use. misalignment phenomenon. [0003] figure 1 Shows the existing female mold positioning device for fan blades, such as figure 1 As shown, the upper mold 1 and the lower mold 2 are installed on th...

AI Technical Summary

Problems solved by technology

[0004] But the above-mentioned female mold positioning device of the fan blade has the following problems: because the concave block 7 and the convex block 6 are connected with the mold clamping mechanism 5 by threads, so long-term use under the situation that the thread pair pretightening force is not enough will cause the concave block 7 and bump 6 are loose, resulting in inaccurate positioning

Once the clamping mechanism 5 or the steel frame 4 is deformed, the concave block 7 and the convex block 6 not only lose their positioning function, but may further damage the clamping mechanism 5 or the steel frame 4
