Description

Servo rotary device of punching machine table Technical Field The utility model relates to the technical field of punching machine table structures, in particular to a servo rotary device of a punching machine table. Background The stator and the rotor are used as core components of the motor, and the lamination quality of the stator and the rotor directly affects the energy efficiency and the operation stability. The traditional stator and rotor stamping production adopts a progressive die continuous blanking process, and the silicon steel sheet is blanked into an annular stamping sheet and then overlapped and formed. In the actual production process, the rotor core is mainly formed by laminating a plurality of rotor punching sheets, and as the thicknesses of different areas of the rotor punching sheets in the production process are different, once all the rotor punching sheets are laminated, the errors in the same area are accumulated and overlapped, so that the rotor core has poor uniformity, and finally the performance of the rotor core is influenced. There is a need for a novel servo swivel device for a press table that solves the above-mentioned problems. Disclosure of utility model The utility model provides a servo rotary device of a punching machine table, which solves the problems that a rotor iron core generates thickness errors during processing and production of a stator and a rotor of the existing punching machine table and the quality and precision of a product are poor by performing technical transformation on the existing stator and rotor punching machine table. In order to achieve the above purpose, the utility model adopts the following technical scheme: The utility model provides a servo slewer of punching machine platform, installs the stamping die department that sets up in the punching machine platform, stamping die includes mould and lower mould, lower mould department is provided with servo slewer, servo slewer includes gyration axle sleeve and driving motor, and gyration axle sleeve rotates with the lower mould to be connected and sets up, be provided with in the gyration axle sleeve and pile up the chamber, pile up the superimposed layer that the chamber is used for storing stator or rotor punching, the last driving motor that installs of punching machine platform, driving motor is connected with gyration axle sleeve drive and is set up. Preferably, the rotary shaft sleeve is rotatably connected with the lower die through a fixed support bearing. Preferably, the driving motor is a servo motor, the output end of the servo motor is in transmission connection with the rotary shaft sleeve through a coupler, the punching machine table is further provided with a servo motor encoder, and the servo motor encoder is used for controlling the servo motor to drive the rotary shaft sleeve to rotate. Preferably, the driving motor is mounted on a motor mounting bracket through an adjusting support piece, and the motor mounting bracket is fixedly connected with the punching machine table through a punching machine connecting plate.
