The driving device comprises a servo motor and a screw rod pair connected with the servo motor and the second sliding table, and the screw rod pair is connected with a rotating shaft of the servo motor through a coupler.
The rotary driving device comprises a rotary servo motor and a rotary platform arranged on the first sliding table and in transmission connection with the rotary servo motor, and the workpiece shaft is arranged on the rotary platform.
Advantageous effects
The utility model discloses because be connected with pressure sensor between the first slip table of each work cell and the second slip table, accessible pressure sensor detects the pressure that the work piece received the rubbing head during polishing, when the work piece of each station appears the pressure nonconformity because of the thickness tolerance of assembly error and rubbing head, pressure sensor will detect the change formation pressure feedback of pressure, pressure feedback system is according to pressure feedback numerical value, the first slip table of control servo motor drive and second slip table seesaw, thereby make every independent work piece remove self suitable position, guarantee the work piece side polishing pressure unanimity of a plurality of stations of simultaneous processing, guarantee processingquality, improve the yields, the solution is different because of the polishing pressure that each station work piece received, influence product quality, lead to the higher problem of defective index.
The technical scheme of the utility model is further explained in the following with the attached drawings.
