In pin hole.
Further, the retaining mechanism further includes the stop screw for limiting pin shaft axial movement, the limit spiral shell
Nail is mounted in the threaded hole opened up in square pin.
Further, the side of the square pin offers the axis hole for installing pin shaft and wear-resistant sleeve.
Further, the stop screw top offers the second spiral shell closed with the corresponding threaded holes opened up in square pin
Line, lower part offer the locking groove for limiting pin shaft play.
Further, first of the screw slots and installation locking nut for fixing stop screw is offered on the pin shaft
Screw thread.
Further, the circular hole that the wear-resistant sleeve outer surface is equipped with positive stop key and stop screw end can be made to pass through.
Further, the wearing layer of laser welding is equipped in the axis hole, with a thickness of 0.5mm.
Further, the wearing layer of laser welding is equipped in the screw slots, with a thickness of 0.5mm.
Further, the material of the wear-resistant sleeve is cast copper alloy.
Compared with the existing technology, the retaining mechanism of the present invention for connecting the backup wing and tool has following excellent
Gesture：
Retaining mechanism of the present invention for connecting the backup wing and tool can in the case where locking nut fails
Ensure that pin shaft does not generate axial movement, prevent it from falling off, improve the safety that intelligent drilling tool uses, has wide
Application prospect.
