Description
Technical field
This utility model relates to a kind of rotary table.
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 to be generally adopted the mode of servo-actuating device cooperation deceleration device to be driven back to revolving worktable rotation, but owing to the revolving dial volume of this kind of mode is big, structure is complicated, have impact on the bearing capacity of entirety, 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 purpose of this utility model is to provide a kind of compact conformation, the rotary table that running accuracy is high.
To achieve these goals, this utility model have employed following technical scheme:
Rotary table, including 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, the outer ring of described deep groove ball bearing and board base inner wall bottom fix, the inner ring of described deep groove ball bearing and centration axis bottom fix, the lower section being positioned at deep groove ball bearing inner ring in described centration axis is further fixed on synchronous pulley, the position corresponding with synchronous pulley, described board base bottom is fixed with encoder feedback detecting device, the sidewall of described board base is additionally provided with cylinder lock fixed pole, and the top of cylinder lock fixed pole is fixed with friction brake wafer.
Preferably: the upper end of described rotor is provided with a recess, described rotor is fixed by bottom and the inwall of recess and crossed roller floating bearing inner ring, 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.
Preferably: the cylinder lock fixed pole in described board base side wall is provided with multiple, and multiple cylinder lock fixed pole become even circumferential to arrange.
Preferably: between top and the board base side wall of described cylinder lock fixed pole, be additionally provided with sealing ring.
Preferably: the lower end of described cylinder lock fixed pole is connected to control for brake electromagnetic valve.
Stator and the rotor of servomotor are directly anchored on rotary table top and base by this utility model, structure is compacter, running accuracy is substantially increased by encoder feedback detecting device with coordinating of synchronous pulley between rotation platform with base, when this utility model ensure that revolving dial quits work also by the cylinder lock fixed pole set up on base with friction brake wafer, the situation of rotation will not be continued because of inertia, further increase precision.
This utility model support accuracy is high, and rigidity is strong, electromechanical, mechanical driving error, and by putting the detection of several times greater encoder feedback, even if driving than general associated mode, detection control accuracy improves several times.
