Specific implementation mode
As shown in Fig. 1 to 5, a kind of marine rear shaft propeller clamp nut assembly tooling, including casing 1, setting are in casing 1
Interior tube 2 and the positioning pipe 3 being arranged in tube 2；
It is equipped with the first flange 11 in casing 1, plane bearing 7 is installed on the first flange 11,2 one end of tube is resisted against
On plane bearing 7, multiple first universal rolling wheels 61 are fixed in casing 1, tube 2 is pressed on each first universal rolling wheel 61；
It is equipped with the second flange 21 in tube 2, multiple second universal rolling wheels 62 are fixed in tube 2, outside positioning pipe 3
A plurality of axial grooving 31 corresponding with each second universal rolling wheel 62 is offered on wall, each second universal rolling wheel 62 is arranged in each item
In grooving 31；
More jackscrews 5 are installed on positioning pipe 3, clamp nut 4 to be assembled is arranged in positioning pipe 3, and each jackscrew 5 is inserted
Enter in 4 blind hole of clamp nut to be assembled, 4 one end of nut to be assembled is resisted against on the second flange 21.
The operation principle and application method of the utility model be：
The first step：Clamp nut 4 is assembled in positioning pipe 3, then each jackscrew 5 is screwed into 3 blind hole of positioning pipe,
Positioning pipe 3 to be fixedly connected with clamp nut 4, then positioning pipe 3 is inserted into tube 2, it is desirable that each second universal rolling wheel
62 fall in each grooving 31 on positioning pipe 3, and finally tube 2 is inserted into casing 1.
Second step：Two chain blocks 10 are hung on crane hook, two chain blocks 10 connect with 1 both ends of casing respectively
It connects, while in lifting, it is desirable that casing 1 is higher than 1 other end of casing equipped with 4 one end of nut, makes 7 stress of plane bearing, prevents simultaneously
Only nut 4 is dropped out from casing 1.
Third walks：Loop wheel machine will press nut 4 to be hung to 13 one end of tailing axle, by adjusting two chain blocks 10, with to nut 4
The angle of inclination of axis is finely adjusted.
4th step：Nut 4 is pushed to be resisted against on tailing axle 13, then to after coaxial nut 4 and 13 axis trimming of tailing axle again
Worker rotates tube 2, and tube 2 drives positioning pipe 3 to rotate by the second universal rolling wheel 62, and at the same time, grooving 31 is along second
Universal rolling wheel 62 moves axially, and nut 4 is slowly screwed on tailing axle 13.
5th step：After nut 4 is painstaking, casing 1, tube 2 and positioning pipe 3 are removed, clamp nut 4 is so far completed and pre-installs.
Further include lifting cross bar 12,12 both ends of lifting cross bar are connect by a chain block 10 with 1 both ends of casing respectively.
Lifting cross bar 12 can facilitate suspension chain block 10, facilitate operation.
It is installed with supporting rack 8 in 1 remotely located pipe of casing, 3 one end, one is separately installed in 8 upper and lower ends of supporting rack
A first laser rangefinder 91, the laser beam that two first laser rangefinders 91 are sent out can pass through clamp nut to be assembled
4 threaded holes, when chain block 10 lifts clamp nut 4, laser beam that two first laser rangefinders 91 are sent out constitutes the
One plane is perpendicular to horizontal plane.
In use, by adjusting the angle of inclination of nut 4, the numerical value that first laser rangefinder 91 is shown also changes therewith,
By the distance that two first laser rangefinders 91 are shown adjust to it is equal when, then represent 4 axis of nut and be in 13 axis of tailing axle
On same plane, at this moment worker just only needs 4 or so both direction of adjusting nut that can adjust nut 4 and tailing axle 13 to same
Axis improves efficiency of assembling to facilitate worker quickly to determine the folding and unfolding amount of two chain blocks 10.
It is separately installed with a second laser rangefinder 92, two second laser rangefinders 92 in 8 left and right ends of supporting rack
