Abstract

A grinding tool comprises a frosting mechanism and a transmission mechanism. The frosting mechanism comprises a grinding wheel and a locating wheel. The transmission mechanism comprises a guide wheel and a drive motor. The grinding wheel and the locating wheel are arranged on one side of the guide wheel. Work space is arranged between the guide wheel and the grinding wheel. One end of the work space is arranged on a locating point. A workpiece is mounted in the work space. A base is arranged on the lower portion of the position between the grinding wheel and the guide wheel and provided with a locating wheel handle. The locating wheel is mounted on the locating wheel handle. The position and direction of the locating wheel can be controlled through the locating wheel handle. A tension spring is arranged at the top end of the locating wheel handle. The left end of the workpiece in the work space abuts against the locating point all the time, and therefore the phenomenon of forward moving is avoided when the workpiece is ground, it is guaranteed that the fixed position of the workpiece is ground, and grinding precision is improved. A roller wheel set is arranged at the upper end of a movable supporting plate, the workpiece on the roller wheel set can easily rotate under the action of the guide wheel, manual participation in workpiece rotation is reduced, and grinding efficiency is improved.

Description

A kind of grinding tool
