Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
See Fig. 1 to Fig. 3, present embodiments provide the axial alignment device of axle pipe part 11, comprise frame 1, frame 1 is rotated and is provided with forward lead screw 2, forward lead screw 2 left end is provided with left outside thread segment, forward lead screw 2 right-hand member is provided with right outside thread segment, the rotation direction of left outside thread segment and right outside thread segment is contrary, left outside thread segment and right outside thread segment have been threaded outward left slider 3 and right slide block 4 respectively, forward lead screw 2 drives it to rotate by driving mechanism, driving mechanism comprises the motor 5 connected successively, decelerator 6, clutch 7 and gear pair 8, decelerator 6 and clutch 7 is driven thus driving gear wheel set 8 is rotated by motor 5, and then drive forward lead screw 2 to rotate, left slider 3 and right slide block 4 upper end are connected to the swing arm 9 extended forward, in the middle part of swing arm 9, below is provided with the rotating shaft 10 of a vertical direction, rotating shaft 10 upper end is through in the middle part of swing arm 9, and swing arm 9 can be rotated along rotating shaft 10, and swing arm 9 front end is used for the end of impeller-hub pipe part 11.
The below of left slider 3 and right slide block 4 is respectively arranged with a line slideway extended in left-right direction 12, left slider 3 and right slide block 4 can move around along the line slideway 12 below it respectively, play good guide effect to move left and right along forward lead screw 2 left slider 3 and right slide block 4.
Frame 1 is provided with rotating shaft mount pad 13, rotating shaft mount pad 13 upper end is provided with installing hole, and rotating shaft 10 is arranged in installing hole, and is embedded with Nonlubricated bearing between rotating shaft 10 and installing hole inwall.Because rotating shaft 10 may produce micro-rotation under the drive of swing arm 9, micro-rotation that Nonlubricated bearing can realize rotating shaft 10 is set, and Nonlubricated bearing is high without the need to lubricating oil, wearability.
Swing arm 9 is the Z-shaped swing arm be made up of rear horizontal segment, vertical section and front horizontal segment, and front horizontal segment height is higher than rear horizontal segment height, and vertical section is connected with the front end of rear horizontal segment with front horizontal segment rear end respectively.Swing arm 9 is set to Z-shaped swing arm herein, for the axle pipe part 11 such as needing to hole concerning axial centre, drilling equipment is arranged on the below of axle pipe part 11, carry out installing drill aperture apparatus owing to needing to reserve certain space and be convenient to bore operation, therefore now axle pipe part 11 height is overhead higher, and the fixing anvil block 16 of placed axis pipe part 11 is also higher; But forward lead screw 2 overhead again can not be too high, if because forward lead screw 2 is overhead too high, the left slider 3 of its correspondence and line slideway 12 size of right slide block 4 and below all will increase a lot, installing space limited and waste material, therefore now just need to arrange Z-shaped swing arm to adapt to the difference in height of forward lead screw 2 and axle pipe part 11.
The rear portion of swing arm 9 is provided with waist-shaped hole 14, and the major axis of waist-shaped hole 14 extends along fore-and-aft direction, swing arm 9 is connected on left slider 3 or right slide block 4 through after waist-shaped hole 14 by screw 15.When left slider 3 or right slide block 4 move along forward lead screw 2, corresponding swing arm 9 can be driven to rotate around rotating shaft 10, in motion process, the line at screw 15 center and rotating shaft 10 center can along with changing, therefore need to arrange this waist-shaped hole 14 at swing arm 9 rear portion to adapt to the change of the line at screw 15 center and rotating shaft 10 center, facilitate screw 15 to slide along waist-shaped hole 14.
The course of work of the axial alignment device of the axle pipe part 11 that the present embodiment provides is as follows:
This device is driven by motor 5, rotated by decelerator 6, clutch 7 driven gear secondary 8 successively, and then drive forward lead screw 2 to rotate, because the external thread section rotation direction at forward lead screw 2 two ends is contrary, therefore the left slider 3 rotarily driving its two ends of forward lead screw 2 and right slide block 4 do counter motion along forward lead screw 2, thus drive two swing arms 9 to rotate backward around corresponding rotating shaft 10 respectively.When left slider 3 and right slide block 4 move along the outer end of forward lead screw 2 respectively; the front end of two swing arms 9 can be moved to the inner; when engagement shaft pipe part 11 one end, front end of one of them swing arm 9 just can impeller-hub pipe part 11 to intermediary movements; after the front end of another swing arm 9 contacts with the other end of axle pipe part 11; axle pipe part 11 just stop motion; the moment of torsion of now swing arm 9 increases; electromagnetic clutch 7 can automatically be thrown off, protection motor 5 nonoverload and axle pipe part 11 indeformable.Namely complete the axial alignment operation of axle pipe part 11, next can carry out next step processing to axle pipe part 11.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
