Abstract
The invention relates to a rotary indexing structure of a rotary worktable, which comprises a rotary table, an upper fluted disc, a rotary support, a lower fluted disc, a piston, a cylinder body, a mandrel and a rotary cone body, wherein the upper fluted disc is connected with the rotary table through a bolt; the lower fluted disc is connected with the piston through a bolt; the upper and lower parts of the rotary support are connected with the rotary table and the rotary cone body respectively through bolts; the mandrel is connected with the rotary cone body through a bolt; the piston is in matched connection with the rotary cone body through a flat key; and the piston, the cylinder body and the mandrel are in matched installation to form upper and lower oil chambers A and B. The rotary indexing structure of the rotary worktable provided by the invention is simple and reasonable in structure, and the way that the upper fluted disc, the worktable and the workpiece which are lifted upward is changed to downward movement of the lower fluted disc. As the lower fluted disc is lighter than the upper fluted disc, the worktable and the workpiece, the lower fluted disc is more convenient and agile to drive. As the upper fluted disc and the worktable only rotate, the upper fluted disc and the worktable can be supported on a large roller bearing so that the bearing capacity is greater than that originally and the workpiece is stable to rotate.
Description
Technical field
The present invention relates to a kind of rotary table circular index structure, a kind of specifically rotary table that is used for accomplishing through the fluted disc engagement calibration function belongs to the Machining Technology field.
Background technology
In prior art, the dividing movement of index table generally is divided into workbench and lifts, circular index and fall and clamp three steps; During assembling, will go up fluted disc and be connected, will go up fluted disc before the calibration earlier and lift with panoramic table; The last lower tooth disk of engagement is thrown off, drive by Power Drive Unit then and go up the fluted disc revolution, go up that fluted disc drives workbench and workpiece falls to the certain angle; Last lower tooth disk meshes again, accomplishes the location.Fluted disc, workbench, workpiece lift this index table simultaneously owing to need upward, and this three's weight is bigger, so required hoist cylinder thrust also need be very big, and the revolution action is surely uneven, carries limitation.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of rotary table circular index structure is provided, this workbench is in light weight, drives also more light and flexible; Because last fluted disc and workbench are only done gyration, can it be supported on the large-sized roller bearing, bearing capacity is bigger than original, and the workpiece revolution is steadily.
According to technical scheme provided by the invention, a kind of rotary table circular index structure comprises turntable, goes up fluted disc, pivoting support, lower tooth disk, piston, cylinder body, mandrel and revolution stage body; The said fluted disc of going up is connected with turntable through screw, and lower tooth disk is connected with piston through screw; The top and the bottom of pivoting support are connected with the revolution stage body with turntable through screw respectively; Mandrel is connected with the revolution stage body through screw, and piston is connected through flat key with the revolution stage body.After said piston, cylinder body and mandrel cooperate installation, form A, the last lower oil cavitie of B.
As further improvement of the present invention, said mandrel is that rotary hole cooperates in the centre of gyration and the turntable of turntable.
As further improvement of the present invention, said turntable is connected with gear ring through screw.
Compared with present technology the present invention has the following advantages:
The present invention is simple and reasonable for structure, last fluted disc, workbench and workpiece three is upwards lifted change moving downward of lower tooth disk into; Since lower tooth disk weight on fluted disc, workbench and workpiece three in light weight, drive also more light and flexible; In addition, because last fluted disc and workbench are only done gyration, can it be supported on the large-sized roller bearing, bearing capacity is bigger than original, and the workpiece revolution steadily.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, the present invention mainly is made up of turntable 1, last fluted disc 2, gear ring 3, pivoting support 5, lower tooth disk 6, piston 7, cylinder body 8, mandrel 9 and revolution stage body 10.Last fluted disc 2 is connected with turntable 1 through screw, and lower tooth disk 6 is connected with piston 7 through screw; The top and the bottom of pivoting support 5 are connected with revolution stage body 10 with turntable 1 through screw respectively, and gear ring 3 also is connected with turntable 1 through screw.Mandrel 9 is connected with revolution stage body 10 through screw, and while mandrel 9 cooperates as rotary hole in the centre of gyration of turntable 1 and the turntable 1.After piston 7, cylinder body 8 and mandrel 9 cooperate installation, form A, the last lower oil cavitie of B; Piston 7 cooperates through flat key 11 with revolution stage body 10.
When the oil-feed of A chamber, piston 7 moves downward, and drives lower tooth disk 6 and moves downward, and throws off with last fluted disc 2, makes workbench be in the released position.At this moment, drive gear rings 3 with the gear 4 of the input gear shaft of gear ring 3 engagement and rotate fluted disc 2, turntable 1 revolution in the corresponding drive; To the precalculated position, oil pocket B oil-feed, oil pressure is upwards lifted piston 7; Driving lower tooth disk 6 moves upward; With last fluted disc 2 engagements, turntable 1 is clamped on the revolution stage body 10, thus the calibration location of accomplishing this rotary table circular index structure.
It moves downward through lower tooth disk, throws off with last fluted disc, is driven by Power Drive Unit then and goes up the fluted disc revolution, thereby drive workbench and workpiece revolution, and lower tooth disk moves upward to the certain angle, and last lower tooth disk meshes again, accomplishes and locatees.
