Multi-axis driving device for double-faced grinding machine

Abstract

The invention discloses a multi-axis driving device for a double-faced grinding machine. The device comprises a sun wheel transmission system, an upper disc transmission system and a lower disc transmission system, wherein the sun wheel transmission system comprises a sun wheel driving motor which is connected with a sun wheel hollow shaft with a sun wheel through a gear transmission device; the upper disc transmission system comprises an upper grinding disc driving motor which is connected with a central shaft with an upper grinding disc through the gear transmission device; the lower disc transmission system comprises a lower grinding disc driving motor; an output shaft of the lower grinding disc driving motor is connected with a lower grinding disc hollow shaft provided with a lower grinding disc and a gear ring hollow shaft provided with a gear ring through the gear transmission device respectively; the central shaft is fixed on a bottom plate; and the sun wheel hollow shaft, the lower grinding disc hollow shaft and the gear ring hollow shaft are coaxially arranged on the central shaft in turn. The device has the advantages of wide speed adjusting range, high grinding and polishing accuracy, high grinding efficiency and the like and is stably operated.

Description

technical field [0001] The invention relates to the field of grinding and polishing equipment, in particular to a multi-axis drive device for a double-sided grinding machine. Background technique [0002] At present, most double-sided grinding machines are driven by a single motor, such as "gantry type double-sided grinding machine" (patent number: CN101927451A) and "high-precision double-sided grinding machine" (patent number: CN201235498Y). All are driven by a single motor. The defect is that the speed of the sun gear, upper grinding disc, lower grinding disc and ring gear cannot be adjusted independently. Limited by the fixed gear transmission ratio, the change of the motion track of double-sided grinding is limited, and it is difficult to pass the motion parameters. The adjustment improves the distribution of the workpiece motion trajectory and improves the accuracy of grinding and polishing the workpiece. Contents of the invention [0003] The purpose of the present ...

Problems solved by technology

All are driven by a single motor. The defect is that the speed of the sun gear, upper grinding disc, lower grinding disc and ring gear cannot be adjusted independently. Due to the limitation of the fixed gear transmission ratio, the change of the trajectory of the double-sided grinding process is limited, and it is difficult to pass the motion parameters. The adjustment improves the distribution of the workpiece motion trajectory and improves the accuracy of grinding and polishing workpieces
