Embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out lower premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementation
Example.
Referring to Fig. 1 to Fig. 3, the axial alignment device of axle pipe part 11, including frame 1, frame 1 are present embodiments provided
Upper rotation is provided with forward lead screw 2, and the left end of forward lead screw 2 is provided with left outside thread segment, and the right-hand member of forward lead screw 2 is provided with spiral shell outside the right side
Line section, left outside thread segment and right external thread section it is oppositely oriented, be threaded with respectively outside left outside thread segment and right external thread section
Left slider 3 and right sliding block 4, forward lead screw 2 drive its rotation by drive mechanism, motor 5 that drive mechanism includes being sequentially connected,
Decelerator 6, clutch 7 and gear pair 8, decelerator 6 and clutch 7 is driven to enter so as to which sliding tooth wheel set 8 rotates by motor 5
And forward lead screw 2 is driven to rotate；Left slider 3 and the upper end of right sliding block 4 are connected to the swing arm 9 extended forward, under the middle part of swing arm 9
Side is provided with the rotating shaft 10 of a vertical direction, and the upper end of rotating shaft 10 is through the middle part of swing arm 9, and swing arm 9 can rotate along rotating shaft 10, pendulum
The front end of arm 9 is used for the end of impeller-hub pipe part 11.
Left slider 3 and right sliding block 4 are respectively arranged below a line slideway extended in left-right direction 12, left slider
3 and right sliding block 4 can move back and forth respectively along line slideway 12 below, so as to left slider 3 and right sliding block 4 along positive and negative
Screw mandrel 2, which moves left and right, plays good guide effect.
Rotating shaft mounting seat 13 is provided with frame 1, the upper end of rotating shaft mounting seat 13 is provided with mounting hole, and rotating shaft 10 is arranged on installation
In hole, and Nonlubricated bearing is embedded between rotating shaft 10 and inner wall of the hole installing.Because rotating shaft 10 may under the drive of swing arm 9
It can produce micro- rotation, set Nonlubricated bearing to realize micro- rotation of rotating shaft 10, and Nonlubricated bearing is without lubricating oil, resistance to
Mill property is high.
Swing arm 9 is the Z-shaped swing arm being made up of rear horizontal segment, vertical section and preceding horizontal segment, and preceding horizontal segment is highly higher than rear water
Flat section height, front end of the vertical section respectively with preceding horizontal segment rear end and rear horizontal segment is connected.Swing arm 9 is arranged to Z-shaped herein
Swing arm, for for the axle pipe part 11 that for example needs to drill to axial centre, drilling equipment is arranged on central siphon class zero
The lower section of part 11, drilling equipment is installed and is easy to bore operation due to needing to reserve certain space, therefore now central siphon class
The height of part 11 from the ground is higher, and the fixation anvil block 16 for laying axle pipe part 11 is also higher；But forward lead screw 2 is from the ground again
Can not be too high, if because forward lead screw 2 is too high from the ground, its corresponding left slider 3 and right sliding block 4 and the line slideway of lower section
12 sizes are intended to increase a lot, and installing space is limited and waste of materials, therefore now just needs to set Z-shaped swing arm positive and negative to adapt to
The difference in height of screw mandrel 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, passed through by screw 15
Swing arm 9 is connected on left slider 3 or right sliding block 4 after waist-shaped hole 14.When left slider 3 or right sliding block 4 move along forward lead screw 2
When, corresponding swing arm 9 can be driven to be rotated around rotating shaft 10, in motion process, the line meeting at the center of screw 15 and the center of rotating shaft 10
With changing, it is therefore desirable to the waist-shaped hole 14 is set at the rear portion of swing arm 9 to adapt to the center of screw 15 and the center of rotating shaft 10
The change of line, screw 15 is facilitated to be slided along waist-shaped hole 14.
The course of work of the axial alignment device for the axle pipe part 11 that the present embodiment provides is as follows：
The present apparatus is driven by motor 5, passes sequentially through decelerator 6, the drive gear pair 8 of clutch 7 is rotated, and then driven positive and negative
Screw mandrel 2 rotates, and because the external thread section at the both ends of forward lead screw 2 is oppositely oriented, therefore the rotation of forward lead screw 2 drives its both ends
Left slider 3 and right sliding block 4 do counter motion along forward lead screw 2, so as to drive two swing arms 9 to make instead rotating around corresponding rotating shaft 10
To rotation.When left slider 3 and right sliding block 4 move respectively along the outer end of forward lead screw 2, the front end of two swing arms 9 can be inside
End movement, when front end 11 one end of engagement shaft pipe part of one of swing arm 9 will impeller-hub pipe part 11 to centre
Motion, after front end and another end in contact of axle pipe part 11 of another swing arm 9, the just stop motion of axle pipe part 11,
The moment of torsion increase of now swing arm 9, electromagnetic clutch 7 can disengage automatically, protect the nonoverload of motor 5 and axle pipe part 11 constant
Shape.The axial alignment operation of axle pipe part 11 is completed, next can carry out next step processing to axle pipe part 11.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made within principle etc., should be included in the scope of the protection.
