Description
Technical Field
The utility model relates to a rotary device, especially a rotary supporting device.
Background
The bearing surface of the existing rotary supporting device is in surface contact with the contact surface of a loaded workpiece, and when fine adjustment is needed, sliding friction force between the contact surfaces is large, so that fine adjustment of high precision is difficult to realize.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides a rotate convenient, laborsaving, the high accuracy fine setting's of being convenient for rotary supporting device, concrete technical scheme is:
a rotary supporting device comprises a base, wherein the top of the base is provided with an internal thread; the supporting seat is provided with external threads and screwed on the top of the base; the adjusting rod is fixed on the side surface of the supporting seat; the screw hole is formed in the top of the supporting plate; the inner ring of the self-aligning thrust roller bearing is fixed at the top of the supporting seat, the outer ring of the self-aligning thrust roller bearing is fixed at the bottom of the supporting plate, and the screw hole is positioned on the axis of the self-aligning thrust roller bearing; the anti-falling bolt is fixed at the top of the supporting seat and movably inserted into the screw hole.
Realize being connected with the rotation of work piece through increasing backup pad and thrust self-aligning roller bearing at the top of supporting seat, the anticreep bolt prevents that the backup pad from breaking away from, nevertheless not screwing up, the backup pad can rotate, the backup pad rotates for the supporting seat, drive the supporting seat through adjusting the pole during the adjustment height and rotate, realize the adjustment of backup pad height to avoid taking place sliding friction between work piece and the supporting seat, the fine setting of the high accuracy of being convenient for, it is more laborsaving to operate, especially effect is better when three rotatory strutting arrangement is used for large-scale work piece adjustment level.
Compared with the existing supporting device, the sliding friction is changed into rolling friction, labor is saved during operation, the adjustment is accurate, and the friction damage of the workpiece is avoided by the colleague.
Compared with the prior art the utility model discloses following beneficial effect has:
the utility model provides a pair of rotary supporting device becomes rolling friction with sliding friction, rotates more laborsaving, makes things convenient for the fine setting of high accuracy, avoids rubbing damage workpiece surface simultaneously.
Drawings
Fig. 1 is a sectional view of the present invention.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings.
As shown in fig. 1, a rotary supporting device comprises a base 1, wherein the top of the base 1 is provided with an internal thread; the supporting seat 2 is provided with external threads, and the supporting seat 2 is screwed on the top of the base 1; the adjusting rod 5 is fixed on the side surface of the supporting seat 2; the support plate 4 is further included, and the top of the support plate 4 is provided with a screw hole; the inner ring of the self-aligning thrust roller bearing 6 is fixed at the top of the supporting seat 2, the outer ring of the self-aligning thrust roller bearing 6 is fixed at the bottom of the supporting plate 4, and the screw hole is positioned on the axis of the self-aligning thrust roller bearing 6; the anti-falling bolt 3 is fixed at the top of the supporting seat 2, and is movably inserted into the screw hole.
Realize being connected with the rotation of work piece through increasing backup pad 4 and thrust self-aligning roller bearing 6 at the top of supporting seat 2, anticreep bolt 3 prevents that backup pad 4 from breaking away from, but not screw up, backup pad 4 can rotate, backup pad 4 rotates for supporting seat 2, drive supporting seat 2 through adjusting pole 5 during the adjustment height and rotate, realize the adjustment of backup pad 4 height, thereby avoid taking place sliding friction between work piece and the supporting seat 2, the fine setting of the high accuracy of being convenient for, it is more laborsaving to operate, especially effect is better when three rotary supporting device is used for large-scale work piece adjustment level jointly. Compared with the existing rotary supporting device, the sliding friction is changed into rolling friction, so that labor is saved during operation, the adjustment is accurate, and the friction damage to the workpiece is avoided.
