Description
Technical field
The present invention relates to thin-walled frame clsss part clamp field, more particularly to one kind to add for thin-walled framework series parts milling
The fixture of work.
Background technology
With scientific and technological economic progress, the utilization of thin-walled frame clsss part is also more and more extensive, aviation field and other phases
Aluminium alloy thin-walled FRAME COMPONENTS can all be applied to by closing industry, but deforming and influenceing occur in process in thin-walled FRAME COMPONENTS
Quality is an existing technical barrier.
At present, when being processed to thin-walled framework series parts milling, it is common to use vice workbench is clamped, due to thin-walled
The characteristics of frame clsss part protrudes is wall thickness dimension about 2mm, central dividing plate size about 6mm or so, therefore using this fixed
The defects of larger be present in the mode that position clamps；Firstly, since retained part is long, chucking power is excessive, easily causes specimen holder
Discontinuity, easily it is deformed in process.Secondly, processed for the big thin-walled frame clsss part of length-width ratio, examination
It is larger that torque is deformed in part process, easily produces flexural deformation, and is difficult to control this change by clamping friction power merely
Shape, therefore manufacturing tolerance can be caused, so cause part process after precision do not reach requirement.
By patent retrieval, following known prior art be present：
