Embodiment Construction
[0052] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0053]figure 1 The aero-engine counterweight blade that needs to be processed is shown, and the counterweight blade includes blade body and blade root;
[0054] The blade surface 9 (referred to as the blade shape) needs to be processed on the blade body, and the end of the blade body away from the blade root is the blade crown;
[0055] The blade root includes: blade root end face 1, back arc surface tenon and groove 2, inner arc surface tenon and groove 3, air inlet side 4, air outlet side 6, inner arc radial surface 5, back arc radial surface 7, blade shape and blade root Root transfer surface 8;
[0056] Among them, the tenon groove 3 of the inner arc surface and the tenon groove 2 of the back arc surface are respectively located on the upper and lower sides of the blade root, and the air inlet side 4, the inner arc radial surface 5, the air outlet side 6, ...

The present invention provides a double-station milling alignment method for counterweight blades, which includes the following steps: step S1, installing a clamp on the A-axis transition plate of the machining center, the clamping reference surface of the clamp body faces the positive direction of the Z-axis, and Measure the runout of the clamping reference plane on the clamp body, and continuously adjust the A-axis angle until the reference plane runout is within the set threshold; step S2, install the first blank of the blade on the first station of the clamp body; step S3, Complete the feature processing of the blade root on the first station; step S4, disassemble the second blank of the blade after the processing in step S3 and clamp it on the second station of the clamp body; step S5, use the line measuring probe to perform the second The station is automatically aligned; step S6, after the alignment is completed, use the program after transforming the machining coordinate system to complete the machining of the blade profile and the transition surface between the blade profile and the blade root. The method has the characteristics of high alignment accuracy, high efficiency and low cost.
Description
technical field [0001] The invention relates to the processing technology of an aero-engine counterweight blade, in particular to an alignment method and a fixture for double-station milling processing of an aero-engine counterweight blade. Background technique [0002] The counterweight blades in the aero-engine balance the weight distribution of the entire rotating parts during the operation of the engine, so that the engine can reach a state of static and dynamic balance. It must work stably under the conditions of high temperature, high pressure and high speed, which puts higher requirements on the blade material, machining accuracy and surface quality, and increases the difficulty of milling. [0003] At present, the main steps of milling and processing this type of blade are: clamping the crown part and processing the blade root part; using blade root tenon and groove profiling fixture to clamp the blade root and processing the blade profile; wire cutting to remove the...
