Detailed description of the invention
In order to make those skilled in the art be better understood from this utility model scheme, below in conjunction with this practicality
Accompanying drawing in new embodiment, carries out clear, complete retouching to the technical scheme in this utility model embodiment
State.
As shown in Figures 1 to 5, the peripheral milling chuck of this utility model a kind of band bias driving lever, including bias
Set 1, eccentric driving lever 2, bolt 3 and location screw 4, the side of described eccentric bushing 1 cylindrical has two
Individual with the laterally zygomorphic positioning screw hole of horizontal axis 8, described positioning screw hole 8 is built with location screw 4, institute
State location screw 4 and on eccentric bushing 1, make axially location by hex nut 5, described eccentric bushing 1 cylindrical
Opposite side has arc groove 6, and described arc groove 6 is connected with eccentric bushing 1 endoporus, arc groove 6
Both sides have hole 10 and internal thread hole 9, location, hole, described location 10 and internal thread hole 9 keep with
Axle, described eccentric driving lever 2 is welded by eccentric 11 and driving lever 12 and is integrally formed, and described eccentric 11 fills
In the arc groove 6 of eccentric bushing 1, the head of described bolt 3 axially sequentially passes through on eccentric bushing 1
