Embodiment
Embodiment of the present utility model is done explanation in detail below; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed enforcement mode and concrete operating process, but protection domain of the present utility model 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, be threaded outside left outside thread segment and right outside thread segment 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, speed reduction unit 6, clutch coupling 7 and gear pair 8, speed reduction unit 6 and clutch coupling 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, lower section is provided with the rotating shaft 10 of a vertical direction, rotating shaft 10 upper end is passed 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 for promoting the end of axle pipe part 11.
The lower section 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 left slider 3 and right slide block 4 to be moved left and right along forward lead screw 2.
Being provided with rotating shaft mount pad 13 in frame 1, rotating shaft mount pad 13 upper end is provided with open holes, and rotating shaft 10 is arranged in open holes, and is embedded with Nonlubricated bearing between rotating shaft 10 and open holes inwall. Owing to 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 without the need to lubricating oil, wear resistance height.
Swing arm 9 is the Z-shaped swing arm being made up of rear horizontal section, vertical section and front horizontal section, and front horizontal section height is higher than rear horizontal section height, and vertical section is connected with the front end of rear horizontal section with front horizontal section rear end respectively. Swing arm 9 is set to Z-shaped swing arm herein, for the axle pipe part 11 such as needing axial centre to be holed, boring device is arranged on the lower section of axle pipe part 11, boring device is installed owing to needing to reserve certain space and is convenient to bore operation, therefore now axle pipe part 11 height overhead is 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 lower section all to be increased a lot, limited space and waste material are installed, therefore now just need to arrange Z-shaped swing arm to adapt to forward lead screw 2 and the difference of altitude of axle pipe part 11.
The rear portion of swing arm 9 is provided with waist-shaped hole 14, and swing arm 9, along front and back to extension, is connected on left slider 3 or right slide block 4 by the major axis of waist-shaped hole 14 by screw 15 after waist-shaped hole 14.
