Description
Technical field
The present invention relates to a kind of overlength conducting rod type component process equipment and its centre frames.
Background technology
The High-Voltage Electrical Appliances key components and parts that conducting rod parts are in high-tension switch gear, play through-flow work in the product
With.The draw ratio of the type component is very big（Generally >=15：1）, the concentricity at conducting rod both ends is more demanding（Generally≤
0.5mm）, surface roughness requirements are stringent（Rm3.2）The characteristics of, and due to the through-flow requirement of high voltage, conducting rod outer circle is no longer
Processing only carries out sanding processing, silver-plated after both side ends progress turning.As length≤1.8m of conducting rod, using common in-vehicle
Bed, it is processed using the method on " one top of a folder ", but as conductive pole length increases the increasing with draw ratio, it is original to add
It is curved that work method can cause parts to get rid of, and causes safety accident, while parts being caused to scrap；Add according to general " one top of a folder "
Centre frame processing method, if application publication number is processing of the elongate rod part on center lathe disclosed in CN103611948A
Method, as shown in Figure 1, elongate rod part one end is felt relieved and clamped by scroll chuck, the other end is held out against by tailstock centre, three-jaw
Centre frame is equipped between chuck and tailstock, centre frame carries out centering support by three centering pins to elongate rod part middle part,
Due to elongate rod as scroll chuck rotates so that relative friction between elongate rod and the centering pin of centre frame, in addition elongated
Bar centrifuges force effect when rotated and its pressure between centering pin is made to become larger so that the surface abrasion of elongate rod part adds
Play forms surface pitting, and for the thin and long units as high-voltage conductive rod, surface pitting can influence the electric conductivity of high-voltage conductive rod
Can, although can be handled surface pitting by sand milling mode, metal powder is easy free under high pressure excitation, is caused
High-voltage breakdown seriously affects electric conductivity, cannot meet the requirement of High-Voltage Electrical Appliances.
