Description
Technical field
The present invention relates to turning equipment technical field, especially relate to a kind of retaining ring cylindrical turning anti-deformation device and make
Use method.
Background technology
The retaining ring of AC traction electric motor is typical thin-walled ring parts, in the existing course of processing, for avoiding retaining ring
Retaining ring cylindrical, endoporus circularity over tolerance is caused because of the effect of radially loading grip force after cylindrical turning, the problem of internal-and external diameter wall thickness variation,
In finish turning, clamping is avoided radially clamping power as far as possible.The most generally carry out clamping with the male half coupling positioning tool having 1 groove fixed
Position, utilizes claw by fixture positioning spigot spreading, reaches to clamp the purpose of retaining ring inner hole refined turning.Because of fixture location circumference only
Opening a groove, inner circle is under the effect of the chucking power of claw, and the spreading degree at each position is the most not quite identical (such as opening
Spreading is big, claw corresponding position is big, and remaining position is little), center can occur minor variations.Additionally, radially chucking power is uneven
Even, after causing turning, after pine claw, the deformation of retaining ring inside and outside round seam increases relatively.
Therefore, how to eliminate when finish turning retaining ring, the deformation of retaining ring that cylindrical clamping causes be those skilled in the art urgently
Solve the technical problem that.
