Abstract

The invention discloses a grinding wheel rod tool-changing assembly. The tool-changing assembly comprises a grinding wheel rod, the grinding wheel rod is provided with a connector and is connected with the axis of a main shaft through the connector, and the grinding wheel rod tool-changing assembly further comprises a fastening piece, a sliding jacking-out structure and a stop piece; the grindingwheel rod is provided with an operation hole, the fastening piece is movably mounted in the operation hole, the fastening piece and the axis of the main shaft are fixed through threads, and the stop piece is fixedly mounted in the operation hole; the sliding jacking-out structure is slidably mounted in the operation hole and is located between the stop piece and the fastening piece, and the sliding jacking-out structure is provided with a through hole; and the fastening piece rotates relative to the axis of the main shaft through the through hole and moves along the operation hole until the fastening piece abuts against the sliding jacking-out structure, and the grinding wheel rod connector is driven to be separated from the axis of the main shaft through the sliding jacking-out structure.

Description

technical field [0001] The invention relates to the field of numerical control machining, in particular to a grinding wheel rod tool changing assembly. Background technique [0002] The grinding wheel rod assembly is used to assemble the grinding wheel and connect it to the spindle core. The connection accuracy of the grinding wheel rod plays a vital role in the grinding process. The HSK tool system is a new type of high-speed short taper tool holder. Its interface adopts the method of simultaneous positioning of the cone surface and the end surface; due to the use of the hollow cone and the end surface positioning, the radial deformation of the spindle hole and the tool holder during high-speed machining is compensated. difference, and completely eliminate the axial positioning error, making high-speed, high-precision machining possible. This kind of tool holder is more and more common in the application of high-speed machining centers. [0003] But there is following def...
