(2) table base is placed on the Vertical Mill workbench autogenous grinding contour pad iron, detect bearing installed surface and spindle mounting hole and end face, require bearing installed surface circumference, laterally detect, virtual connection is touched in the middle of the endless belt.The inside virtual connection of spindle mounting hole end face endless belt is touched, if do not reach requirement, i.e. reconditioning is to qualified.
(3) bearing installed surface and the spindle mounting hole end face that detects after qualified detected and the record height by circumference etc. in eight minutes.
(4) Vertical Mill rotation draws table to detect thrust roller bearing base ring end face precision, according to eliminating the theory of error principle bearing base ring is installed on the precision optimal location, and mark.The bearing of packing into successively rolls on frame, the bearing and encircles.
(5) according to eliminating the theory of error main shaft is packed in the table base installing hole, draw table to detect each critical surfaces precision.
(6) detected and the record height in eight minutes by circumference etc. detecting on the main shaft after qualified the Biserial cylindrical roller bearing installed surface.
(7) according to eliminating the theory of error ring main shaft of packing into of will dismantling in the Biserial cylindrical roller bearing of roller, detect roller raceway precision to the precision optimal location, and mark.
(8) use the hydraulic pressure oil gun auxiliary, with Biserial cylindrical roller bearing according to the mark main shaft of packing into.
(9) pull down part such as round nut, detect surface jitter on Biserial cylindrical roller bearing outer shroud precision, the interior ring.
(10) use the guiding frock, workbench inner ring and gear ring assembly are loaded on the table base installation site.
(11) manually coil the work inner ring, testing platform inner ring low thrust bearing installed surface precision is pressed detection in eight fens and record heights such as circumference.
(12) according to eliminating the theory of error low thrust bearing base ring is installed on the precision optimal location, and mark.The bearing of packing into successively rolls on frame, the bearing and encircles.
(13) pressing lead wires is measured the gland adjusting pad, the low thrust bearing is carried out pretension install.
(14) table base integral body is hung down, carries out other assembly work.
The invention has the beneficial effects as follows: this method has not only been accomplished the vertical assembling of milling the crucial high precision part of car Compositions of metal-working machines HDVTM160 * 10/8L-MC < 201002502-1008>product of national great special project, and has initiated the assembly method of on vertical grinder, carrying out the high-precision rotary parts; Brand-new assembly technology thought has been proposed; Realized detecting the assembly method of serving as theme with piece test, overproof precision reparation, the assembling of error concealment method, assembling back operating accuracy; Once optimum assembly precision is accomplished and can be guaranteed to reach in assembling, and it is easy to operate, practice thrift human and material resources and assembly period, mechanization and automaticity are high, it is minimum that artifical influence factor is reduced to.Its to machine tool field and even mechanical industry, relevant industries the fit on of high-precision rotary form parts provide a kind of secure, measure, practical, energy-saving and cost-reducing new concept, new technology arranged.
The present invention is under the jurisdiction of the great special project of national science and technology, project number: 2010ZX04001-031.
