Description of the drawings
Fig. 1 is the schematic front view that the present invention is installed below sapphire twin grinder gantry upright post；
Fig. 2 is the dimensional structure diagram that the present invention is installed below sapphire twin grinder gantry upright post；
Fig. 3 is the A partial enlarged views in Fig. 1.
Specific implementation mode
As shown in Figure 1, Figure 2, Figure 3 shows, the balanced type loading device of sapphire twin grinder of the invention is mounted on grinding
10 top of upper disc system of machine is simultaneously sleeved on center splined shaft 6, including the upper company being sequentially sleeved on from top to bottom on splined shaft
Fishplate bar 4, lower connecting plate 7, gear 11.Splined shaft is fastenedly connected with upper junction plate 4 and across the centre bore of lower connecting plate 7；Under
7 lower end both sides of connecting plate are symmetrically installed with cylinder 3, and the mandril of cylinder 3 is fastenedly connected by being fitted in the nut on bar top in upper company
In the screw hole of 4 both sides of fishplate bar, counterweight oil hydraulic cylinder 2 is installed in 3 outside of cylinder on both sides, the mandril of counterweight oil hydraulic cylinder 2 is equally logical
It crosses and is fitted in the nut on bar top and is fastenedly connected in the screw hole of upper junction plate both sides；The rear side of the lower connecting plate 7 is fixedly connected
In on the crossbeam of sapphire twin grinder gantry upright post 1.Output shaft is installed to extend downwardly and wear on 1 crossbeam of gantry upright post
Cross the planet-gear speed reducer 5 of crossbeam, the planet-gear speed reducer gear of output shaft lower end and the gear 11 for being set in splined shaft lower part
Engagement, is covered with closing lid 8 in the power train of planet-gear speed reducer gear and gear 11, closing lid bottom is provided with Level tune seat
