The inner surface of nut 3 is threadedly coupled, and the outer surface of the jam nut 3 is threadedly coupled with right grinding wheel clamp holder 6.
In the present embodiment, two-way locking in order to realize, the rotation for avoiding grinding wheel 7 from generating when being acted on by cutting force makes mechanism
It loosens；The screw thread of the screw 4 and main shaft 5 screws direction and the screw thread of screw 4 and jam nut 3 screws direction phase
Instead, and the screw thread of the screw 4 and jam nut 3 screws direction and the screw thread of jam nut 3 and right grinding wheel clamp holder 6 screws
Direction is identical.
In the present embodiment, realize that fine motion clamping or fine motion are unclamped to pass through pitch difference；The screw 4 and main shaft
The screw pitch of screw thread between 5 is 1.5mm, and the screw pitch of the screw thread between screw 4 and jam nut 3 is 2mm, jam nut 3
The screw pitch of screw thread between right grinding wheel clamp holder 6 is 2mm.
In the present embodiment, in order to left grinding wheel clamp holder 1 and right grinding wheel clamp holder 6 are mounted on main shaft 5；The screw
4 be socket head screw, and the right end of screw 4 is equipped with the first external screw thread for being threadedly coupled with main shaft 5, screw 4
Left end be equipped with the second external screw thread for being threadedly coupled with jam nut 3, the inner surface of the jam nut 3 equipped with for
The internal screw thread of the second external screw thread connection of screw 4, the outer surface of jam nut 3 be equipped with for right 6 screw thread of grinding wheel clamp holder
The third external screw thread of connection.
In the present embodiment, in order to left grinding wheel clamp holder 1 being connect with right grinding wheel clamp holder 6 so that grinding wheel 7 is clamped in left sand
It takes turns between clamp holder 1 and right grinding wheel clamp holder 6, and guarantees the concentric of left grinding wheel clamp holder 1 and right grinding wheel clamp holder 6, so as to centering installation sand
Wheel 7；The left grinding wheel clamp holder 1 is fixedly connected by eight screws 2 with right grinding wheel clamp holder 6, and left grinding wheel clamp holder 1 is equipped with installation
Hole, right grinding wheel clamp holder 6 are equipped with and extend into the socket part in mounting hole to the left, equipped with being used for and jam nut in socket part
