Alignment tool capable of achieving cylindrical grinding on long-axis-type part and using method of alignment tool

Abstract

The invention relates to the technical field of mechanical machining, in particular to an alignment tool capable of achieving cylindrical grinding on a long-axis-type part and a using method of the alignment tool. The alignment tool is installed at the outer side of one side of the installation end of the long-axis-type part and is close to one end of a grinding machine head, and comprises a sleeve and a snap ring which are integrally connected, wherein the inner diameter of the snap ring is equal to the outer diameter of the installation end of the long-axis-type part. A replaceable centre stand can be inserted in the sleeve, and a conical groove of the replaceable centre stand is matched with a centre. Four through holes with inner threads are uniformly and symmetrically formed in the snap ring, and can be in thread fit with jacking screws to squeeze the installation end of the long-axis-type part tightly. The alignment tool is utilized, and the cross alignment method of utilizing four symmetric points for clamping the part by 90 degrees is adopted. The alignment operation is precise and convenient.

Description

technical field

[0001] The invention relates to the technical field of mechanical processing, in particular to a straightening tool for grinding and machining outer circles of long shaft parts and a use method thereof. Background technique

[0002] Cylindrical grinding of the slender turbine shaft of the aero-engine, due to the influence of the deformation caused by the thin-walled machining of the parts, the openness of the part structure is poor, the material of the processed part is a material that is easily deformed, the deformation is relatively large after turning, and the dimensional accuracy and position accuracy It is difficult to guarantee, which brings difficulties to the post-process processing. The outer circle runout of various parts is 0.02mm, and the coaxiality is The verticality of the outer circular end face relative to the reference is 0.01mm, so it is extremely difficult to process, the precision diameter tolerance is 0.015mm, and the relative reference...
