Technical field
The invention belongs to thin-walled parts processing technique fields, and in particular to a kind of inwall processing structure of thin-wall long and thin pipe fitting
And outer wall processes structure.
Background technique
In processing wall thickness small (wall thickness is between 0.5mm~2mm), big (thin-wall long and thin of the length in 200mm or more) of length
In the process of pipe fitting, the clamping to part is usually to use the direct holding parts one end of lathe three-claw, then again to thin-wall long and thin
Pipe fitting is processed, and still, be occur the problem that 1. lathe three-claw chuck clamping force is easy to press from both sides part in this way and is deformed；②
Since part is longer, lathe spindle, so that the tail end of part will appear shaking, is used in this case during running at high speed
Lathe tool is cut, and is that part can not be effectively machined to specified size and surface accuracy.
Part shakes in order to prevent, is usually also withstood part using lathe tailstock thimble, but pass through practice have shown that, this
The part that sample processes also will appear some offset issues in part central region size, load onto intermediate fixed frame with
Afterwards, although slightly increasing the processing dimension and surface accuracy of slender rectangular tube, its processing dimension and surface accuracy still without
Method is met the requirements, and this method is more troublesome in clamping parts, inefficient.
Therefore, how the thin-walled that a kind of structure is simple, effectively improves pipe fitting cutting size and surface accuracy can be provided
The inwall processing structure and outer wall of slender rectangular tube process structure, and becoming those skilled in the art has technical problem to be solved.
Summary of the invention
