Large-moment direct-drive plane rotary platform device

Abstract

The invention belongs to the technical field of an operation platform and relates to a large-moment direct-drive plane rotary platform device. A base, a core shaft, a coil winding, a hydraulic cylinder, a hydraulic seat, a reading head seat and a reading head are fixed through bolts to integrally form a stator; a rotor is formed by a tabletop, a hydraulic sheet, a magnet yoke and a magnetic railing ruler; the stator is coupled with the rotor through a bearing and is fixed in an inner ring of the bearing by a bolt; the rotor is fixed on an outer ring of the bearing by a bolt; glue is filled into the coiling winding to be encapsulated, and magnetic steel is stuck on the magnet yoke by glue; stamp gum is coated on the back face of the magnetic railing ruler, and magnetic railing rule is directly adhered to the tabletop; the hydraulic cylinder and the hydraulic seat are sequentially fixed on the base; the hydraulic sheet is fixed between the hydraulic seat and a pressing head of the hydraulic cylinder of the tabletop; the reading head and the reading head seat are sequentially fixed on the base; the coil winding is uniformly wound and fixed on the core shaft; and the magnetic railing ruler is fixed on the side face of the tabletop. The large-moment direct-drive plane rotary platform device disclosed by the invention has the advantages of simple structure, easiness in control, large moment, stability in rotation, high positioning precision, long service life and friendly working environment.

Description

Technical field: [0001] The invention belongs to the technical field of operating platforms, and relates to a high-torque direct-drive planar rotary platform device, which is used in platform occasions requiring rotation, such as engineering machinery, medical equipment, aerospace, military fields, catering industry, construction industry, and wind power generation. Background technique: [0002] The existing direct-drive planar rotary platform devices are divided into many different structures, but they all have shortcomings such as small torque, complex structure, and inconvenient use and operation. , large speed adjustment range, and high-precision direct-drive rotary platforms are attracting more and more attention; the usually used direct-drive rotary platforms should cancel the worm gear mechanism required by ordinary platforms, without any intermediate conversion mechanism, which can not only eliminate Factors such as elastic deformation, clearance and friction of the...
