Description

Motor drive assembly of grinding machine Technical Field The utility model relates to the technical field of couplings, in particular to a motor driving assembly of a grinding machine. Background The motor is widely applied to our daily production and life, and is an essential device for industrial production. The power source type can be classified into a direct current motor and an alternating current motor according to the power source type, and the power source type can be classified into a direct current motor, an asynchronous motor and a synchronous motor according to the structure and the working principle. When the motor drives other machines to work, the motor needs to be connected with an output shaft of the motor by using a coupler, so that power is transmitted. The existing shaft coupling is basically in coaxial connection, a grinding sheet at the bottom of the grinding machine can generate a large amount of heat due to friction when the grinding machine grinds, the heat is conducted to the joint of the shaft coupling, and the heat can cause the thermal expansion of the connecting shaft, so that the clearance exists between an output shaft of a motor and the shaft coupling, the installation accuracy is affected, and abnormal sound and vibration are generated when the grinding machine grinds. Disclosure of utility model The present utility model is directed to a motor driving assembly of a grinder, which solves the above-mentioned problems. In order to achieve the above purpose, the motor driving assembly of the grinder comprises a motor output shaft, wherein a motor connecting flange is arranged at the top end of the motor output shaft, two first fixing pieces are fixedly connected to the lower end of the motor connecting flange, a grinding block connecting disc is arranged below the motor connecting flange, a grinding disc connecting disc is fixedly connected to the upper end of the grinding block connecting disc, a second fixing piece is fixedly connected to the upper end of the grinding disc connecting disc, a coupler is arranged between the first fixing piece and the second fixing piece, bolts are connected to the top ends of the second fixing pieces in a threaded mode, and a shell is arranged on the outer side of the motor output shaft. Preferably, the motor flange is a columnar structure with a large upper end diameter and a small lower end diameter, a screw is inserted in the middle of the lower end of the motor flange, two ends of the screw penetrate through the motor flange, the upper end of the screw is in threaded connection with the motor output shaft, and the threaded connection direction is opposite to the rotation direction of the motor output shaft. Preferably, the coupling comprises two fixing pieces, the two fixing pieces are oppositely arranged, two through holes are formed in the middle of the fixing pieces, the first fixing piece and the second fixing piece are of rectangular structures, and the first fixing piece and the second fixing piece are inserted into the two through holes respectively. Preferably, the first fixing piece and the second fixing piece are oppositely arranged, and a gasket is arranged between the coupler and the bolt. Compared with the prior art, the coupling has the beneficial effects that the two fixing pieces are arranged to form the coupling, the first fixing piece and the second fixing piece are inserted into the two sides of the coupling, and when the second fixing piece is heated and expanded, the connection of the first fixing piece is not influenced, so that the connection precision is ensured, the situation of deviation in the process of power transmission is avoided, and the situation of vibration in the process of grinding the ground is avoided.
