Description
Technical field
The utility model belongs to the hydraulic test technical field, particularly relates to a kind of hydraulic control synchronous rotating device.
Background technology
What the synchronous rotating device of known mobile revolution pressure head frame hydraulic press adopted at present is slewing bearing, because slewing bearing must be installed between rotary table and the travelling table, therefore on slewing bearing, must be processed with gear ring, require gear ring machining accuracy height like this, and the processing technology complexity, so plant the slewing bearing material alternative costs and the processing technology cost height of structure; Above-mentioned in addition synchronous rotating device drives and controls by motor, decelerator and frequency converter, use investigation, analyze according to market and user, has the high advantage of precision though adopt motor, decelerator and frequency converter to drive and control synchronous rotating device, but its cost is also very high, because what most of users in use all considered is the height of cost, the cost that therefore reduces synchronous rotating device has become a difficult problem of being badly in need of solution.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, in the hydraulic control synchronous rotating device of processing and low cost of manufacture.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The hydraulic control synchronous rotating device, be included in two sill installed inside travelling table is arranged, rotary table is equipped with on travelling table top, the travelling table bottom is equipped with the jacking cylinder that is provided with the jacking cylinder piston in it, the travelling table bottom is equipped with worm gear, worm screw and mother lead screw, at the worm screw inner ring feed rod is housed, gear shaft is connected by key with worm gear, being positioned at the travelling table two bottom sides also is fixed with the sill guide pass and is the copper guide plate that is slidingly matched, it is characterized in that: be equipped with on the floating bearing in the rotary table bottom and enclose, floating bearing is circle and ball down, floating bearing encloses the last plane contact with the jacking cylinder piston down, the joint portion that is positioned at rotary table and travelling table is equipped with dust-proof seal ring, is connected with rotary encoder in the gear shaft bottom.
Advantage and the good effect that the utlity model has are: because the utility model has adopted floating bearing to enclose structure with ball up and down, and by fluid motor-driven control rotary table, make the structure of synchronous rotating device not only be convenient to processing, reduce material cost and processing cost, and simple in structure; In rotary table and travelling table joint portion sealing ring being installed can increase its dust reduction capability, can accurately control the angle of revolution of rotary table in addition by the rotary encoder that is installed in the gear shaft bottom, working stability, efficient height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. sill, 2. travelling table, 3. rotary table, 4. circle on the floating bearing, 5. ball, 6. floating bearing circle, 7. floating bearing encoder, 8. jacking cylinder piston, 9. jacking cylinder, 10. gear shaft, 11. worm gears, 12. dust-proof seal rings, 13. copper guide plates, 14. sills, 15. mother lead screws, 16. feed rods, 17. worm screws down.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Tu, the hydraulic control synchronous rotating device, be included in two sills 1 and 14 installed inside travelling table 2 is arranged, travelling table 2 tops are equipped with rotary table 3, the travelling table bottom is equipped with the jacking cylinder 9 that is provided with jacking cylinder piston 8 in it, the travelling table bottom is equipped with worm gear 11, worm screw 17 and mother lead screw 15, at worm screw 17 inner rings feed rod 16 is housed, gear shaft 10 and worm gear 11 are connected by key, being positioned at the travelling table two bottom sides also is fixed with sill 1 guide pass and is the copper guide plate 13 that is slidingly matched, be equipped with in rotary table 3 bottoms and enclose 4 on the floating bearing, floating bearing is circle 6 and ball 5 down, the last plane contact of circle 6 and jacking cylinder piston 8 under the floating bearing.The joint portion that is positioned at rotary table and travelling table is equipped with dust-proof seal ring 12, can increase the dust reduction capability of rotary table like this.Be connected with the rotary encoder 7 that accurately to control the rotary table angle of revolution in gear shaft 10 bottoms.
Operation principle of the present utility model is:
When this hydraulic control synchronous rotating device is in running order, it is out of gear mesh enclosing 6 on the floating bearing under circle 4 and the floating bearing, when rotary table 3 needs revolution, jacking cylinder piston 8 in the jacking cylinder 9 moves upward, the jack-up floating bearing is circle down, makes to enclose on the circle and floating bearing floating bearing play to contact and be kept in motion.Hydraulic motor drives feed rod 16 rotations at this moment, and feed rod drives worm gear 11 and worm screw 17 is rotated, and gear shaft 10 rotations, and gear shaft drives rotary table and does synchronous gyration.
