The specific embodiment
Below with reference to the accompanying drawings, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, 2, a kind of air-flotation type rotary table, comprises panoramic table 1, base 2, central shaft 3, piston 4.
Base 2 centers have mating holes, and piston 4 is arranged in the mating holes of base 2; On the cylindrical fit face contacting with base 2 at piston 4, offer closure gasket groove on piston, sealing ring 5,6 is arranged in closure gasket groove.Piston 4 is contained in the mating holes of base 2, by the sealing function of side seal circle 5,6, makes piston 4 and base 2 between upper and lower mating surface, form ring-type air cavity 7, and ring-type air cavity 7 is connected to device of air by gas piping 8, to give air cavity air feed.On gas piping 8, be provided with reversing switch 9 and air cleaner 10, reversing switch 9 for controlled pressure gas into and out of, air cleaner 10 for moisture and the impurity of filtering compressed air, guarantee to pass into the clean and dry of pressure air.Under the effect of ring-type air cavity 7, piston 4 can lifting.
Further, for the rising space of limited piston 4, at the upper end face of base 2, also closing restraining position ring block 11, the upward stroke of limited piston 4, has guaranteed that piston can not depart from and coordinate with the mating holes of base.
Central shaft 3 puts together on the bottom surface of panoramic table 1, both concentrics, as shown in Figure 4.On central shaft 3, be with rolling bearing 12, install in piston 4 and the common center mating holes of base 2 together with central shaft.Further, location copper sheathing 13 is housed in base 2 center mating holes, is positioned at the below of rolling bearing 12, as shown in Figure 5, after central shaft 3 is inserted in copper sheathing 13, copper sheathing 13 has guaranteed the concentric of panoramic table 1 and base 2.
Panoramic table 1, under the supporting role of central shaft 3, is placed on base 2 and piston 4, and the mating surface of panoramic table 1 and base 2, piston 4 guarantees that by facing-up two contact-making surfaces in plane and inclined-plane contact simultaneously.
On panoramic table 1, be provided with 0 °, 30 °, 45 °, 60 °, 90 °, 180 ° several anglecs of rotation, be provided with dowel hole at these angle places, accurately locate with alignment pin 15.Other rotary angle position is estimated location by the rule 14 on panoramic table 1 circumference, and owing to being human eye range estimation location, poor accuracy generally can only use in the rough machined situation of blank.
On base 2, the dowel hole coordinating with panoramic table 1 is set, alignment pin 15 inserts wherein, for accurately locking the angle of revolution of panoramic table 1.Top at panoramic table 1 is also provided with pressing plate 16, for compressing panoramic table 1, itself and base 2 is fitted tightly.
When work, workpiece is placed on panoramic table 1, and gas piping 8 is given after ring-type air cavity 7 injection pressure gases, piston 4 drive panoramic table 1 and on all workpiece upwards promote together, the faying face of panoramic table 1 and base 2 disengages; After the limited ring 11 of piston 4 is spacing, stop motion, now because the faying face of panoramic table 1 and base 2 disengages, lose frictional resistance, rotate 1 of panoramic table and need to overcome the rolling frictional resistance that rolling bearing 12 produces, therefore operator can promote easily panoramic table 1 and turn to the angle needing.Insert after alignment pin 15 lockings, rotating switch 9 commutates, and makes air cavity internal pressure air pressure relief (having leakage port 17 on rotating switch 9), panoramic table 1 and on workpiece because the effect of gravity falls after rise downwards together, again fit with base 2, fasten with pressing plate 16.Due to panoramic table 1 again with base 2 laminating after original horizontal accuracy remain unchanged, accurately locate with alignment pin 15 angle of revolution simultaneously, the workpiece therefore clamping on panoramic table 1, without centering again, can directly carry out the processing of next process.
