Problems solved by technology

Due to the manufacturing tolerance of the upper journal itself, the one-way compression causes the center of the blade to deviate, and the phenomenon of "eating" tolerance occurs; due to the non-directional offset of the center of the lower journal due to deformation relative to the centerline of the blade, the V-shaped Block positioning is difficult to ensure the clamping positioning accuracy of the lower journal

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0030] Such as figure 1...

Abstract

The invention discloses a double-journal rectifying blade center hole drilling clamp and a using method thereof. The double-journal rectifying blade center hole drilling clamp comprises a bottom plate and a support vertically arranged on the bottom plate. A cutter handle is arranged on the bottom plate and used for clamping an upper journal of the double-journal rectifying blade, a floating supporting assembly is arranged on the support and used for carrying out floating supporting on a lower journal of the double-journal rectifying blade, a locking mechanism is arranged on the support and used for locking the floating supporting assembly, a pressing mechanism is arranged on the support and used for pressing the lower journal of the double-journal rectifying blade. According to the double-journal rectifying blade center hole drilling clamp, the upper journal of the double-journal rectifying blade is clamped through the cutter handle, and due to the automatic centering function of the cutter handle, phenomenon that the center of the blade deviates due to the fact that the upper journal has manufacturing tolerance and one-way pressing can be effectively avoided; the floating supporting assembly is used for forming floating supporting on the lower journal, the external force borne by a blade body and the lower journal can be ignored, the double-journal rectifying blade parts are basically in a natural state to be positioned and pressed, and the influence of deformation caused by external stress is eliminated.

Description

technical field [0001] The invention relates to the technical field of double journal straightening blade processing, in particular to a double journal straightening blade center hole drilling jig and a use method thereof. Background technique [0002] The structure of the double journal rectifying blade of the aeroengine is as follows: figure 1 As shown, it has an upper journal, a lower journal and an airfoil. After the airfoil processing is completed, the thinning of the airfoil produces deformation, which causes the center of the lower journal to deviate from the centerline of the blade. The state is tight, and finally when the outer circle of the lower journal of the blade is finished, the centerline of the blade, the centerline of the center hole of the lower journal, and the top axis of the CNC lathe are not collinear. It is difficult to meet the guarantee of the center of the outer circle of the lower journal of the blade. The accuracy requirements for the line to b...
