Background technology

Along with manufacturing development, Digit Control Machine Tool is towards high speed, high precision int, flexibility, high reliability development.Rotary table is as the main function components of Digit Control Machine Tool, and its function and parameter directly have influence on working ability and the precision of lathe.Current rotary table all adopts mechanical transmission, the processing and manufacturing of spindle box body and main spindle box internal gear all has strict demand, therefore its processing technology is comparatively complicated, and due to the existence of mechanical drive train, make turntable complete startup, acceleration, reversion and disengaging movement time, the distortion of easy generation frame for movement, friction and backlass is there is between transmission, rotary table is caused to there is mechanical oscillation and noise in the course of the work, and then have influence on the dynamic rate of rotary table, the high-precision requirement in the rotary table course of work cannot be met.

Summary of the invention

In order to solve the problem, the purpose of this utility model is to provide a kind of large main arbor direct-drive type rotary table structure, this structure eliminates traditional mechanical type gear drive, torque motor is adopted directly to drive rotary table to rotate, the stator of torque motor and rotor put together on table base and workbench respectively, encoder is relied on to complete the closed loop servo feed system of rotary table, i.e. the calibration location of rotary table.The continuous division of angle can be realized fast and there is the features such as transmission efficiency is high, noise is little, compact conformation, precision are high, reliability is high, easy to maintenance.

The utility model solves the technical scheme that its technical problem adopts: a kind of large main arbor direct-drive type rotary table structure, is made up of workbench, table base, torque motor stator, torque motor rotor, connector, thrust ball bearing A, thrust ball bearing B, Biserial cylindrical roller bearing, desktop, ring flange A, encoder, ring flange B, ring flange C, briquetting, main shaft.Torque motor stator puts together on table base, and torque motor rotor puts together on connector, and connector and workbench are closing.Connector is seated on table base by thrust ball bearing A, and connector endoporus and Biserial cylindrical roller bearing outer shroud are connected, and Biserial cylindrical roller bearing is arranged on main shaft, and main shaft is connected with table base centre bore also closing.The briquetting put together on main shaft is connected with connector by thrust ball bearing B.The stator of encoder is fixed on ring flange C, and ring flange C is fixed on main shaft, and the rotor of encoder is fixing on the table by ring flange A, ring flange B.Workbench centre bore is connected with desktop, and desktop puts together on ring flange B.

Structure design principle: cancel traditional mechanical type gear drive, torque motor is adopted directly to drive rotary table to rotate, the stator of torque motor and rotor put together on table base and workbench respectively, rely on encoder to complete the closed loop servo feed system of rotary table, the continuous division of angle can be realized fast and there is the features such as transmission efficiency is high, noise is little, compact conformation, precision are high, reliability is high, easy to maintenance.

The beneficial effects of the utility model are: main shaft direct-drive type rotary table structure eliminates traditional mechanical type gear drive, directly drive rotary table to rotate with torque motor, make its continuous division that can realize angle fast and there is the features such as transmission efficiency is high, noise is little, compact conformation, precision are high, reliability is high, easy to maintenance.The present invention can meet today's numerical control lathe towards high speed, high precision int, flexibility, high reliability future development trend.The automatization level of the advanced lathe of China can be increased substantially, drive the development of whole machine-tool industry.The utility model is the outstanding youth fund project in Heilongjiang Province, and contract number is: JC201318.
