A main shaft fixing seat (31) is installed in an inner hole of a gear installation plate (30), the main shaft fixing seat (31) is used for placing a main shaft (46) and a bearing structure, the main shaft (46) can rotate on the main shaft fixing seat (31), an inner gear transmission wheel (43), a lower grinding disc transmission wheel (44) and a main shaft transmission wheel (45) are installed on a shaft sleeve and a shaft of the main shaft (46) from top to bottom respectively, three gears are driven by two groups of different transmission mechanisms respectively, the transmission structure of a lower grinding disc assembly (10) of a grinding machine is mainly driven by two motors, namely a main shaft motor (34) and a lower grinding disc motor (37), the main shaft motor (34) drives a main shaft speed reducer (32) through a main shaft triangular belt (33) belt wheel transmission structure and drives a main shaft driven wheel (40) installed on the speed reducer, and the main shaft driven wheel (, the large driven wheel drives the coaxial transmission wheel (42) to drive the internal gear transmission wheel (43) to rotate, the gear drives the tool internal gear (36) to rotate, and the small driven wheel drives the spindle transmission wheel (45) to drive the spindle (46) to rotate the tool external gear (35) arranged on the spindle. The lower millstone motor (37) drives a lower millstone driven wheel (41) on a lower millstone speed reducer (39) to rotate through a transmission structure for driving a lower millstone triangular belt (38), so that the lower millstone driven wheel (44) meshed with the lower millstone driven wheel rotates together through the driven wheel, and the rotation action of the lower millstone (28) of the grinder is completed.

6. The device for grinding the glass of the vehicle window according to claim 1, characterized in that the grinding wheel dressing device (7) is mainly used for repairing the upper and lower grinding discs, the whole structure is composed of a telescopic structure, the positioning of the tool is completed, the device for driving the telescopic arm (48) of the dresser is composed of a moving slider ball screw (53), a transmission synchronous belt and a belt pulley (57), and a motor (54) with a speed reducer, the moving slider ball screw (53) is installed on the guide rail (52) of the guide rail frame (47) of the dresser, the motor (54) with the speed reducer is installed on the upper part of the guide rail frame (47) of the dresser, the motor is used for driving the ball screw of the moving slider ball screw (53) to rotate by the transmission synchronous belt and the belt pulley (57), so that the moving slider makes a linear motion on the ball screw, one side of the moving slider is fixedly installed on one side of the telescopic arm, thereby, the trimmer telescopic arm (48) can also do linear telescopic motion along the guide rail (52).

7. The apparatus for grinding vehicle window glass according to claim 6, wherein the trimming tool guide rail bracket (47) is provided with an adjustable resistance type proportional distributor (51) at one side and oil pipe holes at the other side, so that lubricating grease can be uniformly injected onto the trimmer telescopic arm (48) through the distributor, and the precision of the telescopic operation is ensured. An upper dovetail sliding groove seat and a lower dovetail sliding groove seat (50) are installed on the end face of the outer side of the trimmer telescopic arm (48), a tool holder seat (49) is installed on the dovetail sliding groove seat (50), a repairing tool can be installed on the tool holder seat (49), and the tool can slide up and down on the dovetail sliding groove seat (50) through the tool holder seat (49) to adjust the height of the tool. A dial indicator (55) and a telescopic arm adjusting screw (56) are arranged at the lower part of the knife repairing device guide rail frame (47), the horizontal position deviation of the trimmer telescopic arm (48) can be observed through the dial indicator (55), and calibration is carried out through the telescopic arm adjusting screw (56).
