Embodiment
Name preferred embodiment, and become apparent from intactly illustrating the present invention with reference to accompanying drawing.
The invention discloses a kind of jewel bearing workpiece and its installation method.Install what the first jewel bearing 2 to be used
Instrument is as shown in figure 1, putting in order and be followed successively by respectively from top to bottom：Upper installing handle 1, the first jewel bearing 2, jewel bearing work
Part 3, the first pedestal 4, lower installing handle 5, back-moving spring 6 and the axis of guide 7；Lower installing handle has installing handle cavernous structure 17, leads
It is arranged in axle in lower installing handle cavernous structure, back-moving spring is sheathed on the axis of guide, and is installed on lower installing handle and the axis of guide
Between.Likewise, upper installing handle also has installing handle cavernous structure 18 on one, for being cooperated jointly to the first jewel with lower installing handle
Bearing presses.
First have to adjust the central shaft and the first pedestal mounting hole 15 of installing handle 1, make both concentricitys in 0.01mm
Within scope, and the upper installing handle for adjusting air press installs pressure limit between 0.35MPa to 0.4MPa.Secondly by jewel
Bearing component is put into the first stopper slot 11, and the first pedestal mounting hole 15 is axially aligned with workpiece installing hole 19, and by work
Part mounting hole 19 is nested on the external cylindrical surface of lower installing handle 5.At the same time, and with tweezers by the first jewel bearing it is positioned over work
Instead in corner apertures 13 (C0.1*45 °), the first jewel bearing is worn to be penetrated in lower installing handle 5 (as shown in Figure 2) part.
Then, starting air press makes installing handle slowly contact jewel bearing, and is pressed into workpiece installing hole, this
At present installing handle is compressed with back-moving spring, and moves down a jewel bearing thickness distance along the axis of guide.In pressure
Upper installing handle is unclamped after being kept for 3 to 5 seconds, and removes jewel bearing workpiece, lower installing handle recovers former under the driving of back-moving spring
Beginning installation site.
And then second jewel bearing 8 will be installed, the instrument used in the second jewel bearing is installed as shown in figure 3, from upper
To lower putting in order and be followed successively by respectively：Upper installing handle, the second jewel bearing, jewel bearing workpiece, the base of locating axle seat 9 and second
