Abstract

The utility model discloses a grinding wheel machine. A mandrel at one end of the grinding wheel machine is sleeved with a transmission gear and a belt, which are locked and limited by a side cover. The side cover is fixedly provided with a fixing seat. A bushing passes through and is connected with the fixing seat through a screw. A shaft rod passes through the bushing and is provided with a bearing, a sleeve, a regulating block and a driven gear in turn in a penetration manner. Two ends in the driven gear are sleeved with the bearing. The tail end of the shaft rod is locked and provided with one regulating block. A limit screw is locked and arranged inside the regulating block. A grinder is arranged at one end of the bushing through the screw. The rotating speed of the grinding speed can be improved through tooth number proportion difference of the transmission gear and the driven gear and the regulated torque force value is kept smaller than the force used by the user to hold the socket of the grinder by regulating the torque value between the grinder and a bushing group, consequently when the grinding wheel machine is started, the grinder is held and can not oscillate in the uncertain direction along with a flexible pipe thereof. Therefore, nearby workers can not be hurt.
