After riveting, the large end of the stepped hole still has enough depth to drive the coupling interface 6.
- a drive pin distributed along the stepped hole is disposed on the flange of the inner blade drive shaft output end, and the cooperation of the drive pin and the drive coupling interface 6 is a clearance fit or an over fit.
- the drive pin provided on the flange of the inner blade drive shaft output slides into the drive coupling interface 6 disposed at the large end of the stepped hole after riveting; the outer saw blade 1 1 and the bearing inner ring fixedly connected thereto 51 is positioned with the outer blade drive shaft by a fit; the platen screw is screwed into the outer blade drive shaft output
- the kinetic coupling interface is axially coupled by an unconstrained meshing drive; when the outer blade drive shaft and the inner blade drive shaft are rotated in opposite directions, the outer blade 1 1 and the inner blade 21 are respectively driven to perform a reverse rotation pairing motion. . Due to the high positioning accuracy of the bearing 5, the outer saw blade 1 1 and the inner saw blade 21 can freely rotate around the bearing 5.
- the second embodiment implements the design of the rotary-cut composite saw blade of the present invention with a customized bearing, has a simple structure, high positioning accuracy, and is more suitable for mass production operations.
- the above embodiments are merely illustrative of the technical concept and the features of the present invention.
- the purpose of the present invention is to understand the contents of the present invention and to implement the present invention, and the scope of the present invention is not limited thereto. Equivalent variations or modifications made by the spirit of the invention are intended to be included within the scope of the invention.
