Specific implementation mode

As shown in Figures 1 to 4, the utility model swivel slide includes following compositions：The rotation of one pedestal 10, one is set in pedestal 10 The outer barrel 30, one that the inner cylinder 20, one in portion is sheathed on inner cylinder 20 is fixedly arranged on the rotating disk 40 of 30 apical margin of outer barrel, a first bearing 50, a second bearing 60, a locating ring 70, one are connected with the linear actuating device 80 in pedestal 10, wherein first bearing 50, second Bearing 60 is sequentially sheathed on inner cylinder 20 with locating ring 70, and is set between inner cylinder 20 and outer barrel 30.Linear actuating device 80 passes Dynamic outer barrel 30 rotates, and makes outer barrel 30 and rotating disk 40 relative to 10 synchronous rotary of pedestal.

The pedestal 10 has pass through aperture road 11 and a groove 12, and groove 12 is laterally connected with through hole 11, interior Cylinder 20 is fixedly arranged in the groove 12 of pedestal 10.The locating ring 70 is resisted against 50 apical margin of first bearing, and locating ring 70 has at least One screw hole 71, and be set in an at least screw hole 71 by 72 spiral shell of an at least bolt, and coaxially stretch out in locating ring 70 and close on first The free end of the end face of bearing 50, bolt 72 be selectively pressed on 50 apical margin of first bearing and adjust the first and second bearing 50, The distance for the end that 60 phases are closed on.

The linear actuating device 80 includes the drive screw 82 that a motor 81 and one is driven by motor 81, drive screw 82 Rotation is set to the 31 phase bridle joint of external screw thread being equipped in the through hole 11 of pedestal 10 and with 30 periphery wall of outer barrel, the driving transmission of motor 81 Screw rod 82 rotates, and drive screw 82 is driven outer barrel 30 and rotates, and makes outer barrel 30 and rotating disk 40 relative to 10 synchronous rotary of pedestal.

As shown in figure 3, in this example, 11 front end of through hole is equipped with a first bearing seat 13, and 11 rear end of through hole is then set There are a second bearing seat 14,82 front end of drive screw to wear group in first bearing seat 13, group is then worn in second in 82 end of drive screw Bearing block 14, second bearing seat 14 set by 11 rear end of through hole are the thrust that can prevent drive screw 82 from generating axial displacement Formula bearing form, first bearing 50 set by 11 front end of through hole are then the bearing shape for allowing drive screw 82 to generate axial displacement State.Thereby technical characteristic, with when drive screw 82 generates temperature and rise heat expansion phenomenon in operation, the axial of drive screw 82 becomes Shape measurer has the nargin space extended outwardly, to prevent drive screw 82 from generating bending when heat expansion.

As shown in figure 4, in this example, outer barrel 30 has a plurality of mounting holes 32, and rotating disk 40 is with a plurality of corresponding Mounting hole 41, outer barrel 30 and rotating disk 40 utilize an at least fixing piece 90, are fixed on the mounting hole 32 and rotating disk of outer barrel 30 40 mounting hole 41, to combine outer barrel 30 and rotating disk 40.

As shown in figure 4, in this example, the groove 12 of pedestal 10 is equipped with a plurality of mounting holes 121, and 20 bottom peripheral edge of inner cylinder to Outer to extend the ring convex portion 21 that is equipped with, groove 12 utilizes an at least fixing piece 91 with inner cylinder 20, is fixed on the mounting hole 121 of groove 12 And 21 periphery of ring convex portion of inner cylinder 20, with engagement groove 12 and inner cylinder 20.

In other examples, can also only have first bearing 50 between the two in inner cylinder 20 and outer barrel 30, and make For the effectiveness for undertaking radial load between the two.
