A hardened internal spline vibration lapping with internal expansion lapping stick and its using method

Abstract

The application belongs to the technical field of grinding and discloses a hardening inner spline vibration grinding inner expansion tightening grinding rod and a use method thereof, which comprises a bottom cover, a top cover, a wedge-shaped inner spline tooth groove column designed in a sleeve shape and having one thick end and one thin end, a plurality of clamping grooves uniformly distributed on the circumferential surface of the wedge-shaped inner spline tooth groove column, a wedge-shaped inner spline tooth having one thick end and one thin end, two opposite clamping teeth matched with the clamping grooves arranged on the lower surface of the wedge-shaped inner spline tooth, a grinding rod, the wedge-shaped inner spline tooth groove column being clamped on the grinding rod, the wedge-shaped inner spline tooth being inserted into the wedge-shaped inner spline tooth groove column, the bottom cover and the top cover being respectively installed at the two ends of the wedge-shaped inner spline tooth groove column, the main spring being limited by a nut, and the auxiliary spring being limited by a bolt. The application solves the problems of unstable connection of the vibration grinding inner spline grinding rod, large energy loss, limited grinding efficiency improvement, low replacement efficiency and the like, and has a significant improvement on the fastening effect, vibration energy transmission and grinding rod replacement efficiency.
