Description
Technical field
The present invention relates to a kind of milling tools more particularly to a kind of coupler hook body traction table polishing processing unit (plant)s.
Background technique
Drawbar coupler platform is the main force part between coupler knuckle of car coupler of railway freight car and coupler body, traction table and hook on coupler body
Traction table mutually reclines on tongue, and traction table mutually reclines with traction table under hook bolt under coupler body, and the working face of upper and lower traction table is and lifting lug
Concentric rotary table arcwall face on the basis of the transverse direction 5mm eccentricity of the hole center of circle, when coupling of vehicles is drawn, if in coupler hook body and hook bolt
Lower traction table gap is inconsistent, and traction table stress is inconsistent up and down with hook bolt for coupler body during hitch will be caused to use, and generates
Unbalance loading friction phenomenon easily causes traction table and lifting lug rhegma, influences traffic safety, it is therefore necessary to guarantee coupler hook body hook bolt or more
The concentricity requirement of traction table.
Since traction table working face center of arc is inside two coupler knuckle pin holes, lifting lug hole strength is relatively low, if causing to adopt
It is more difficult with machining tool positioning, and traction table work arc surface, in the intracavitary portion of hook, space is smaller, and process tool passes in and out not
Just, effective means thus at present there is no to solve the polishing or processing problems of traction table circular arc working face.
