Description
Technical field
The utility model is related to through-hole chamfering technical fields more particularly to a kind of non-eccentricity formula through hole double-side rounding cutter to have.
Background technology
Due to setting multiple threaded holes or bolt hole on automobile hub bearing flange face, so in the life of automobile hub bearing
During production, in perforation processing process, need to process multiple through-holes on the flange face of automobile hub bearing（Bolt hole or screw thread
Bottom outlet）, since the positive and negative of through-hole is correspondingly arranged chamfering again, through-hole chamfering adds on current existing automobile hub bearing flange face
Work technique has：First, it carries out the chamfer machining technique of chamfering using chmfer bit and the chamfering of chamfering is carried out using eccentric chamfer knife
Processing technology, the processing technology that the Double-side rounding processing of through-hole is carried out using chmfer bit is that chmfer bit first processes through-hole side
Chamfering when processing through-hole opposite side chamfering, needs to overturn product, then carries out through-hole opposite side chamfer machining, this chamfering
Technique makes the processing efficiency of product reduce, increase product processing cost, is not suitable for the processing of typical products in mass production；2nd, separately there is use
Eccentric chamfer knife carries out the processing technology of the positive and negative surface chamfer of through-hole on the flange face of automobile hub bearing, disclosure satisfy that product is primary
Clamping processes the positive and negative surface chamfer of through-hole, and eccentric chamfer knife includes the axis of knife bar and the cutter head being arranged on knife bar, cutter head and knife bar
Line is misaligned, the axis of cutter head relative to the axis of knife bar in radial deflection a certain distance, the widest part of rose reamer cutter head
Radial dimension is slightly less than the diameter of through-hole.Existing technology carries out leading on the flange face of automobile hub bearing using eccentric chamfer knife
During the chamfer machining in hole, many steps can be included, feed path is more, complicated for operation, invisible when extending production in implementation
Between, reduce the processing efficiency of product.Certainly it is not only have through-hole chamfering needs, other machines in automobile hub bearing flange face
Bed part through-hole similarly needs to carry out chamfering in previous processing.
And in terms of cutter, there are single side chamfering tool and Double-side rounding cutter at present, only there are one letters for single side chamfering tool
Single chamfering cutter head machining, example：The technical solution of 203711942 U of Authorization Notice No. CN only can be suitably used for upper side
The chamfer machining in hole, the reversed chamfering in hole can not process.Double-side rounding cutter can process positive and negative surface chamfer, example：Authorization Notice No.
The technical solution of 203109365 U of CN can be suitably used for both sides chamfer machining, but its is less efficient, and stability is bad, and cutter turns
Speed cannot be too high, is placed on the slow-speed of revolution on common manual tool and uses preferable, progress high speed on unsuitable CNC Machine Tools
It uses.
