Abstract
The invention relates to a measurement tool, in particular to a broaching and adjusting measurement tool for a turbine disk of a combustion gas turbine, solving the problems that the detection can be performed only after the conventional race broaching process is finished, no warning control measurement tool is arranged during the process, problems happening in the broaching process only can be judged according to experience, and no special tool can be used for measuring. The broaching and adjusting measurement tool disclosed by the invention comprises a measurement part and a broaching machine assembling part, which are integrated into a whole. The measurement part is a prismatic table consists of two symmetrical wave-shaped curved surfaces which are shrunk progressively from bottom to top and two symmetrical planes which are shrunk progressively from bottom to top. The cross section of the measurement part is a quadrangle, and the broaching machine assembling part is a prism of which the cross section is a quadrangle. The projections of the two wave-shaped curved surfaces on a horizontal plane are turbine disk tongue-and-groove shaped lines. The broaching and adjusting measurement tool disclosed by the invention is used for measuring the size of race broaching shaped lines.
Description
Technical field
The present invention relates to a kind of measurer, be specifically related to a kind of gas turbine turbine disk broaching tool setting measurer.
Background technology
The turbine disk is the crucial part of Gas Turbine Power turbine part, and crudy directly influences machine performance.Labor content is big in the turbine disk processing, and wherein the broaching difficulty of processing of wheel disc tongue-and-groove is higher, and the wheel disc tongue-and-groove is made up of complicated molded lines; Its tolerance range is between 0.01～0.03mm, and precision is higher, and turbine disk tongue-and-groove exists helical angle and inclination angle; Need broaching machine and anchor clamps common guarantee during broaching; Conventional race broaching can only detect after machining, and middle no early warning control operation or measurer are if go wrong in the broaching process; Can only rely on workman's experience to be judged, not have special-purpose instrument to measure.
Summary of the invention
The present invention can only detect after machining for solving existing race broaching; Middle no early warning control measurer; Go wrong in the broaching process and can only judge by rule of thumb, do not have the measurable problem of specific purpose tool, and then propose a kind of gas engine turbine disk broaching tool setting measurer.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes measure portion and broaching machine assembled portion; Said measure portion and broaching machine connect to join partly processes one; Said measure portion is by two symmetries and the waveform curved surface that is provided with of convergent and two symmetries and the prismoid formed of the plane of convergent from the bottom to top from the bottom to top; The cross section of said measure portion is a quadrangle; Said broaching machine assembled portion is that cross section is tetragonal prism, and two waveform curved surfaces are projected as turbine disk tongue-and-groove molded lines on horizontal plane.
The invention has the beneficial effects as follows: the present invention and broaching machine are used, and both can measure turbine disk tongue-and-groove symmetry, tongue-and-groove helical angle etc., can also in time find the problem that occurs in the broaching process; For the correction correction provides foundation; And easy to use, easy operating, the present invention has improved product quality; Reduce production cost, improved the operating efficiency of race broaching.

The specific embodiment three: combine Fig. 1 that this embodiment is described, the measure portion 1 that the measure portion 1 of the said a kind of gas turbine turbine disk broaching tool setting measurer of this embodiment is made for 40Cr, said broaching machine connects joins part 2 and joins part 2 for the broaching machine of 40Cr making connects.Other composition and annexation are identical with the specific embodiment one.
Operation principle
Job step of the present invention is following:
Step 3, when using, the present invention cooperates with broaching machine;
When step 4, the work of vertical broaching machine broaching tool is vertical state, and turbine disk tongue-and-groove has helical angle, needs during broaching the turbine disk is rotated an angle, when the present invention measures the turbine disk, should keep and turbine disk state consistency.
