Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
As shown in Figure 1, a kind of double rack drives and exchanges the station, comprise board base 1, the center of described board base 1 is vertically fixed with hydraulic jack 2, described hydraulic jack 2 is rotatably connected to one to move up and down and the runing rest 3 rotated in the horizontal direction along it as vertical direction, described runing rest 3 is positioned at two ends and is arranged with two working plates 4, and immediately below the end described board base 1 being positioned at runing rest 3, place is provided with revolution pedestal 5.
As shown in Figures 2 and 3, the center of described hydraulic jack 2 is provided with one and floats oil cylinder 21, the below of floating oil cylinder described in being positioned at is provided with rotary oil cylinder, described rotary oil cylinder comprises the first oil pocket 22, second oil pocket 23, the 3rd oil pocket 24 and the 4th oil pocket 25, described first oil pocket 22 is connected by the first tooth bar 26 with the 3rd oil pocket 24, described second oil pocket 23 is connected by the second tooth bar 27 with the 4th oil pocket 25, is provided with the gear 28 be meshed with it between described first tooth bar 26 and the second tooth bar 27.
Further, the end of described first oil pocket 22, second oil pocket 23, the 3rd oil pocket 24 and the 4th oil pocket 25 is equipped with trimmer valve 221, and the other end is equipped with moveable piston 222.
The operation principle of the present embodiment is:
Being fixed on the hydraulic jack 2 on board base 1, by driving double rack and gears meshing to rotate, making working plate 4 and runing rest 3 rotate 180 ° to finish the work the exchange of platform.When adopting two working plates 4, a piece for processing work, another block can workpiece loading and unloading, decreases processing non-cutting time.
When workbench needs to exchange, hydraulic oil starts to enter the upper oil chamber of floating oil cylinder 21, forces runing rest to drive two pieces of working plates 4 to float; Then, hydraulic oil enters rotary oil cylinder, promotes tooth bar horizontal movement, rotates 180 ° by the engagement driven rotary support 3 of rack-and-pinion and working plate 4; Finally, hydraulic oil enters the bottom oil pocket floating oil cylinder, under the effect of oil pressure and gravity, forces runing rest 3 to drive two pieces of working plates 4 to fall, thus completes the exchange of 1 task platform.
When runing rest 3 needs to rotate, hydraulic oil starts to enter the first oil pocket 22, promote the first tooth bar 26 horizontal movement left, first tooth bar 22 and gear 28 engage, force gear 28 driven rotary support 3 to be rotated counterclockwise, when the piston being fixed on the first tooth bar 26 left part bumps against on the valve piston 222 of left side oil cylinder, valve piston 222 needs to overcome the oil pressure in the 3rd oil pocket 24, thus decrease impact, make stable movement; While the first tooth bar 26 horizontal movement left, after gear 28 can drive the second tooth bar 27 to force the piston on the right side of the second tooth bar 27 to bump against stroke locating piece, rotary motion stops; The principle of other motions is identical, order is contrary.
The utility model is all designed with trimmer valve 221 in the end of four oil pockets, can play good cushioning effect, make rotary motion quick and stable, impact little.Utilize double rack and a gears meshing, the gap of wheel and rack can be eliminated well, make rotary motion accurately and reliably.
