Abstract
The utility model discloses a measuring tool for detecting positions of steam turbine guide vane rivet heads, relates to a measuring tool, and aims to solve the problems that the conventional methods for measuring rivet heads at the top of a guide vane are complex, the measuring error is large, the rejection rate of guide vane production is high, and thus the assembly quality of the guide vanes is influenced. The measuring tool comprises a reference block, a base board, a positioning and clamping mechanism and a locating pin, wherein the base board is a rectangular board body which is horizontally arranged, and the reference block, the positioning and clamping mechanism and the locating pin are mounted from right to left in turn on the upper surface of the base board. The measuring tool provided by the utility model is used for detecting the positions of the steam turbine guide vane rivet heads.
Description
Technical field
The utility model relates to a kind of measurer, is specifically related to a kind of measurer that detects steam turbine guide vane manufactured head position.
Background technology
Some guide vane of steam turbine is mainly laminating assembling and leaf top manufactured head and the riveted joint assembling of shroud hole by blade root assembling inner arc and back of the body arc in the time of assembling.And the whether qualified key that just becomes guide vane assembling of the relative position that detects guide vane leaf top manufactured head.Traditional detection method is whether detect separately guide vane manufactured head size qualified, while detection respectively, due to leaf top manufactured head and the spatial relation more complicated of assembling inner arc and back of the body arc and blade-root molded line, and there is manufacturing tolerance in different measuring tools, cause locating surface disunity, the disunity that this has just caused guide vane product to detect, cannot ensure the position relationship in leaf top manufactured head and shroud hole, have a strong impact on the crudy of guide vane, the rejection rate of product is high, thereby affects the assembly quality of guide vane.
Utility model content
The utility model is the method more complicated that solves existing detection vane tip manufactured head, detection error is large, make the rejection rate of guide vane processing high, thereby affect the problem of the assembly quality of guide vane, and then propose a kind of measurer that detects steam turbine guide vane manufactured head position.
The utility model is to address the above problem the technical scheme of taking to be: a kind of measurer that detects steam turbine guide vane manufactured head position described in the utility model comprises reference block, base plate, positioning and clamping mechanism, register pin, base plate is horizontally disposed rectangle plate body, and reference block, described positioning and clamping mechanism, register pin are arranged on the upper surface of base plate from right to left successively.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, have ensured the measurement unitarity of vane rivet head, have reduced detection error, have ensured blade assembly quality, make the rejection rate of guide vane processing reduce by 20% left and right.Use the utility model, in process, the position relationship that can ensure the blade root assembling inner arc of blade and the pilot hole of blade root assembling back of the body arc and leaf top manufactured head and shroud, all has effective measurement means, thereby guarantees that the crudy of guide vane meets production requirement.
