Lubricated is done to the inwall of the bearing 7：After the bearing 7 is positioned on the knuckle 6, the slide unit
The piston rod of cylinder 29 is stretched out, and the loudspeaker cover plate 31 is covered on the bearing 7.Lubricating oil is after the oil filler point 34 from institute
State atomization mouth 33 to spray, lubricating oil is ejected into the inwall of the bearing 7.
Finally it is pointed out that above example is only the high-accuracy intelligent more representational example of assembly technology of the present invention
Son.Obviously, the high-accuracy intelligent assembly technology of the present invention is not limited to above-described embodiment, can also there is many deformations.Every foundation
Any simple modification that the technical spirit of the high-accuracy intelligent assembly technology of the present invention is made to above example, equivalent variations with
Modification, is considered as belonging to the protection domain of the high-accuracy intelligent assembly technology of the present invention.
Claims (1)
1. a kind of high-accuracy intelligent assembly technology, it is characterised in that comprise the following steps：
1) at feeding station, knuckle is placed on the fixture；Under the driving of rotating disk mechanism, the knuckle reaches profit
At sliding station, the knuckle is located at the bottom of lubricating system；
2) piston rod of slider cylinder is stretched out, and atomizer is entered in oil filler point, and loudspeaker cover plate is covered on the bearing hole, lubrication
After atomization of the oil by the lubricating system, it is ejected on bearing hole, the lubricating system is carried out to the inside of the bearing hole
Lubricated；Then the piston rod of the slider cylinder is retracted；
3) bearing is positioned on the knuckle, the lubricating system is lubricated processing to the inwall of the bearing；Then
The piston rod of the slider cylinder is retracted；
4) bearing and knuckle being rotated by extrusion position in rotating disk mechanism, pressing mechanism is pushed, by pressure
The bearing is squeezed into the bearing hole by head；
5) extruding while, the pressure value collected to pressure sensor is monitored in real time, thus analyze the bearing with
The fit quality of bearing hole, and defer to following criterion：If the pressure value is less than normal value, the chi of the bearing is judged
Very little bigger than normal, the bearing and bearing hole are in loose fit state, assemble off quality；If the pressure value is higher than normal
Value, then interrupt extrusion process at once, and the size of the bearing is less than normal, and the assembling of the bearing and bearing hole is too tight, assembles quality
Unqualified, the knuckle needs repair of doing over again.
