Description
Technical field
The utility model relates to machining equipment field, in particular to a kind of rotary table that can automatically locate.
Background technology
In the production process of larger revolving doors, dissimilar hole to be processed to the arc-shaped workpiece that diameter reaches 5 meters at different directions and multistation.The general method all adopting manual setting-out on workpiece, then utilize hand-operated tools or plain-milling machine to process workpiece at present.Process because adopting manual setting-out and hand-operated tools therefore be difficult to meet to the strict dimension precision requirement of high-grade door, simultaneously manual setting-out also manually processes not only with plain-milling machine that labour intensity is large, and speed is slow, efficiency is low, also often cannot meet the fast reaction to market.
Utility model content
Technical problem to be solved in the utility model is, provides one can automatic pinpoint rotary table.
Therefore, the technical solution of the utility model is as follows:
The rotary table that can automatically locate, comprises circular workbench, servomotor and displacement transducer, wherein:
The Magnetic ruler that institute's displacement sensors comprises inductive head and coordinates with described inductive head, described Magnetic ruler is arranged on the outer peripheral face of described workbench, described inductive head is corresponding with described Magnetic ruler to be arranged and is connected to described servomotor, for detecting the arc length turned over of described workbench outer peripheral face;
Described workbench is rotatably installed by a rotating shaft, and described servomotor is connected to described rotating shaft by decelerator, drives described workbench to turn to predeterminated position for the arc length turned over according to the described workbench outer peripheral face received from described inductive head.
The described rotary table that can automatically locate also comprises pneumatic braking device, for being fixed described workbench when described workbench stops operating.
Also train of reduction gears is provided with between described decelerator and described rotating shaft.
By in the utility model, can realize the automatic location of workbench, precision is high, and reliability is strong, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the rotary table that can automatically locate according to the utility model embodiment;
Fig. 2 is the top view in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As depicted in figs. 1 and 2, according to the rotary table that can automatically locate of embodiment of the present utility model, comprise circular workbench 7, servomotor 1 and displacement transducer, wherein:
The Magnetic ruler 6 that institute's displacement sensors comprises inductive head 10 and coordinates with described inductive head 10, described Magnetic ruler 6 is arranged on the outer peripheral face of described workbench 7, described inductive head 10 is corresponding with described Magnetic ruler 6 to be arranged and is connected to described servomotor 1, for detecting the arc length turned over of described workbench 7 outer peripheral face;
Described workbench 8 is rotatably installed by a rotating shaft, described servomotor 1 is connected to described rotating shaft by decelerator 2, drives described workbench 7 to turn to predeterminated position for the arc length turned over according to described workbench 7 outer peripheral face received from described inductive head 10.
The described rotary table that can automatically locate also comprises pneumatic braking device 11, for being fixed described workbench 7 when described workbench 7 stops operating.
Train of reduction gears 3 is also provided with between described decelerator 2 and described rotating shaft.
Wherein, 4 is backing roll, and 12 is support device of work level.
In the utility model, after servomotor 1 is once slowed down by decelerator 2, secondary speed-reducing is carried out again by train of reduction gears 3 (a pair big speed ratio external gear pump can be adopted), workbench 7 is made to be operated in the comparatively slow-speed of revolution, for increasing the torsional rigidity of workbench 7, train of reduction gears 3 can be fixed on the table 7.
The arc-shaped workpiece 8 of placing diameter on the table 7 and reach 5 meters is bored at multistation, milling digital control processing time, require that rotary table 7 accurately can stop at the correspondence position of brill, milling unit head 8.For this reason, adopt servomotor 1 as driving, system all may be caused when starting and stop to produce distortion for reducing the precision of workbench 7 own and rigidity and large rotating inertia, thus affect the problem of positioning precision.Adopt novel close-loop control mode, namely paste along arc length direction the flexible Magnetic ruler 6 that a circle resolution ratio can reach 0.01mm at the cylindrical of rotary table 7, the cylindrical of rotary table 7 directly can be recorded along arc length precise displacement by Magnetic Induction head 10, and send the action that signal controls servomotor 1, make rotary table 7 and be placed on it the correspondence position that arc-shaped workpiece 8 that diameter reaches 5 meters accurately stops at brill, milling unit head 9, and realize automatically processing it.
All the problem of system variant may be caused because of inertia force when starting and stop for reducing large quality rotary table 7 because of larger rotary inertia, can adopt when rotary table 7 is by stop motion, retarded motion mode is carried out by controlling servomotor 1, reduce inertia force, and start pneumatic braking device 11 when stopping, rotary table 7 is checked, makes it accurately stop at the correspondence position of brill, milling unit head, and realize automatically processing it.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is all included within scope of the present utility model.
