Detailed description of the invention
As Fig. 1, shown in 2 and 3, a kind of auxiliary hydraulic set being convenient to the circular runout of adjustment large-scale precision gear ring, comprise base 4 and bearing block 5, bearing block 5 is arranged on base 4, there is die cavity 6 between base 4 and bearing block 5, base 4 has pressure oil import 7, pressure oil outlet 8 and be communicated with the oilhole 9 that pressure oil import 7 and pressure oil export 8, pressure oil outlet 8 is positioned at the bottom centre of die cavity 6, the pressure oil entering die cavity 6 holds up bearing block 5 from the gap overflow between base 4 and bearing block 5, be provided with in the surrounding of base 4 and spring stop 10 that is spacing and that reset is carried out to bearing block 5, pressure oil passes into die cavity 6 by pressure oil import 7.
The center at the top of base 4 has the circular hole of indent, and the bottom centre of described bearing block 5 has protruding round platform, and round platform embeds circular hole, and be less than the degree of depth of circular hole at the height of round platform, the diameter of round platform is less than the diameter of circular hole.The gap of circular hole in diametric(al) at the round platform of the bottom of bearing block 5 and the top of base 4 is exactly in order to diametric adjustment, and when radial direction adjusts, spring stop 10 can bend with the movement of bearing block 5.Pressure oil pump 2 and the pressure oil tank 3 of this auxiliary hydraulic set are arranged on the centre of workbench 1 and rotate with workbench 1, this auxiliary hydraulic set 11 is arranged on workbench 1 and supports gear ring, pressure oil pump 2 is connected with the pressure oil import 7 of auxiliary hydraulic set 11, after the pressurization of pressure oil in pressure oil pump 2 pairs of pressure oil tanks 3 by Pipeline transport to the pressure oil import 7 of auxiliary hydraulic set 11.
Pressure oil uses the cold oil of machine cut, and cold oil reenters cooling system or the pressure oil tank 3 of equipment after reclaiming.
Utilize the process of the circular runout of this auxiliary hydraulic set adjustment gear ring as follows:
First, gear ring is placed on the bearing block 5 of auxiliary hydraulic set 11, supercharging is carried out by the pressure oil in pressure oil pump 2 pairs of pressure oil tanks 3, gear ring floats under the effect of pressure oil passing into auxiliary hydraulic set 11, now play dial gauge at gear ring cylindrical, and according to the radial position of dial gauge reading adjustment gear ring, until dial gauge reading is in fixed range, now adjust the jaw position of clamping gear ring, and fixing; Then auxiliary hydraulic set pressure release, and again show again at cylindrical, ensure that dial gauge reading is in fixed range.Auxiliary hydraulic set is under artesian condition, and its height adjustment range is about 0.02-0.03mm.
