Description

Integral type revolving dial
Technical field
The present invention relates to integral type revolving dial.
Background technology
Rotary table is vertical lathe, milling machine, machining center, the core component of the multiple lathe such as digital control gear shaper, the kinematic accuracy of rotary table, bearing capacity, the element relationship such as ability of reply impulsive force is to the production and processing ability of whole lathe and efficiency, existing rotary table is improve precision generally to adopt servo-actuating device to coordinate the mode of deceleration device to rotate to drive rotary table, but because the revolving dial volume of this kind of mode is large, complex structure, have impact on overall bearing capacity, and then affect stability, later maintenance and inconvenience thereof, and although the revolving dial of this kind of mode is higher than the rotary table precision of other modes, but still cannot meet high accuracy process requirements.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of compact conformation, the integral type revolving dial that running accuracy is high.
To achieve these goals, present invention employs following technical scheme:
Integral type revolving dial, comprise work top, motor stator, rotor, crossed roller floating bearing, deep groove ball bearing and board base, the central authorities of described work top are fixed with centration axis, described rotor is fixed in the middle part of the outer wall of centration axis, described crossed roller floating bearing is arranged on work top, between rotor and board base, described motor stator is fixed in the middle part of the inwall of board base, outer ring and the board base inner wall bottom of described deep groove ball bearing fix, inner ring and the centration axis bottom of described deep groove ball bearing fix, the below described centration axis being positioned at deep groove ball bearing inner ring is also fixed with synchronous pulley, the position corresponding with synchronous pulley, described board base bottom is fixed with encoder feedback checkout gear.
Preferably: the upper end of described rotor is provided with a recess, described rotor is fixed by the bottom of recess and crossed roller floating bearing inner ring and inwall, the top of described work top and crossed roller floating bearing inner ring fixes, and the outer ring of described crossed roller floating bearing and the top of board base fix.
The stators and rotators of servomotor is directly fixed on rotary table top and base by the present invention, and structure is compacter, substantially increases running accuracy between rotation platform with base by encoder feedback checkout gear with coordinating of synchronous pulley.Support accuracy of the present invention is high, and rigidity is strong, electromechanical, mechanical driving error, and detects by amplifying several times of encoder feedback, even if drive than general associated mode, detection control precision improves several times.
