specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, the gas turbine turbine disc broaching tool setting measuring tool described in this embodiment includes a measuring part 1 and a broaching machine assembly part 2, the measuring part 1 and the broaching machine fitting part 2 are integrated, the measuring Part 1 is composed of two symmetrical wavy curved surfaces 1-1 that taper from bottom to top and two symmetrical planes 1-2 that taper from bottom to top. The cross-section of the measurement part 1 It is quadrilateral, and the broaching machine assembly part 2 is a quadrilateral prism in cross section, and the projection of the two wavy curved surfaces 1-1 on the horizontal plane is the tongue-and-groove profile of the turbine disc. In this embodiment, the dimensions of the two wavy curved surfaces 1-1 in the measuring part 1 are obtained according to the equivalent scaling principle of the wheel groove profile, which is 0.2mm...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 To illustrate this embodiment, a mounting bay 2-1 is provided on the outer wall of the broaching part 2 of a gas turbine disk broaching tool setting tool described in this embodiment. This embodiment ensures that the mating part 2 of the broaching machine is firmly connected with the broaching machine and will not become loose. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 Describe this embodiment, the measurement part 1 of a gas turbine turbine disk broaching tool setting tool described in this embodiment is a measurement part 1 made of 40Cr, and the broaching part 2 is a broaching part 2 made of 40Cr . Other components and connections are the same as those in the first embodiment.

[0010] working principle

[0011] Working steps of the present invention are as follows:

[0012] Step 1. Determine the maximum and minimum physical dimensions of the wheel groove according to the tolerance zone of the wheel groove profile (that is, the shape of the broaching wheel groove in the turbine disk);

[0013] Step 2. Determine the shape of the wheel groove after broaching by the rough broach according to the rough broach. Under the condition that there is no interference with the broaching wheel groove and there is sufficient measurement space, determine the size of the profile part of the...

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 [0001] The invention relates to a measuring tool, in particular to a tool setting measuring tool for broaching a turbine disk of a gas turbine. Background technique [0002] The turbine disk is a very important part of the power turbine part of the gas turbine, and the processing quality directly affects the performance of the whole machine. The machining workload in the machining of turbine discs is heavy, and the broaching of the mortise and groove of the roulette is more difficult. There is a helix angle and an inclination angle in the tenon and groove, and broaching needs to be guaranteed by the broaching machine and the fixture. Conventional wheel groove broaching can only be tested after the processing is completed. There is no early warning control process or measuring tool in the middle. If there is a problem during the broaching process, only It can be judged by the experience of workers, and there is no special tool to measure it. Contents of the...
