Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1 and Figure 2, the oil channel structures of the oil cylinder on the flip-arm of the present invention, comprise: be movably arranged on the trip shaft 3 in the overturning seat 7, trip shaft 3 is fixed together by key 4 and flip-arm 1, flip-arm 1 is provided with the oil cylinder 2 that is used to drive holding limb 16, the hydraulic fluid port 21 of oil cylinder 2 is connected with the oil circuit interface 32 of oil circuit switching device in being arranged on trip shaft 3 by transport pipe 6, and the hydraulic fluid port 22 of oil cylinder 2 is connected with the oil circuit interface 31 of oil circuit switching device in being arranged on trip shaft 3 by transport pipe 5; In the present embodiment, the concrete structure of described oil circuit switching device is: the inwall of overturning seat 7 is provided with two annular oil storage tanks 72 and 74, be provided with respectively in two oil storage tanks 72 and 74 and insert oilhole 71 and 73, oil storage tank 72 is communicated with an oil duct of oil supplying device by inserting oilhole 71, and oil storage tank 74 is communicated with another oil duct of oil supplying device by inserting oilhole 73; Be provided with two airtight switching oil ducts 33 and 34 in the trip shaft 3 vertically, in fact, switching oil duct 33 and 34 can leave uncovered at an end of trip shaft 3 in course of working inevitably, in the present embodiment, the uncovered sealing mechanism that is made of sealing gasket 8, end cap 10 and bolt 13 of transfer oil duct 33 and 34 is sealed; Switching one of oil duct 33 is connected with access oilhole 72 by the attachment hole 35 that is opened on the trip shaft 3, switching one of oil duct 34 is connected with access oilhole 73 by the attachment hole 36 that is opened on the trip shaft 3, switching oil duct 33 and 34 other end offer oil circuit interface 31 and 32 respectively, oil circuit interface 31 is connected with transport pipe 5, and hydraulic fluid port 32 is connected with transport pipe 6.In the present embodiment, also be provided with four road O RunddichtringOs 11 between described overturning seat 7 and the trip shaft 3; In order further to strengthen the sealing effect between overturning seat 7 and the trip shaft 3, between overturning seat 7 and trip shaft 3, also be provided with the seal ring that twice are formed by sealer 12.When practical application, also be provided with thrust-bearing 15 between overturning seat 7 and the trip shaft 3; Described flip-arm 1 is driven by overturning oil cylinder 17.
In actual use, at first start oil cylinder 2 forward work, allow its piston rod outwards eject, make holding limb 9 turn clockwise, the guide rail 18 of needs upset is clamped, then, start overturning oil cylinder 17 forward work, allow its piston rod outwards eject, making flip-arm 1 drive trip shaft 3 turns clockwise in overturning seat 7, thereby guide rail 18 is turned to the right side from the left side of trip shaft 7, then, allows oil cylinder 2 reverse operations, allow its piston rod inwardly bounce back and get back to initial position, in the retraction process of the piston rod of oil cylinder 2, drive holding limb 9 and be rotated counterclockwise, thereby the guide rail 18 of clamping is unclamped, allow guide rail 18 enter next procedure; Finish after the upset of guide rail 18, just can allow overturning oil cylinder 17 reverse operations, allow its piston rod inwardly bounce back, make flip-arm 1 drive trip shaft 3 and in overturning seat 7, be rotated counterclockwise that final flip-arm 1 is got back to the preceding initial position of upset.Below be that example specifically describes its working procedure just with oil cylinder 2 forward work: in oil cylinder 2 forward working procedure, hydraulic fluid port 22 is as filler opening, hydraulic fluid port 21 is as return opening, the oil that is pumped by oil supplying device passes through the access oilhole 71 in the overturning seat 7 successively, attachment hole 35 in annular oil storage tank 73 and the flip-arm 3, switching oil duct 33, oil circuit interface 31 and transport pipe 5, enter into the right piston cavity of oil cylinder 2 by hydraulic fluid port 22, make the piston in the oil cylinder 2 be moved to the left, thereby it is the piston rod on the piston is extrapolated, oil in the oil cylinder 2 left piston chambeies is owing to be subjected to the pushing of piston, from hydraulic fluid port 21, outwards flow out, pass through the oil circuit interface 32 in transport pipe 6 and the flip-arm 3 successively, switching oil duct 34, annular oil storage tank 74 in attachment hole 36 and the overturning seat 7 and access oilhole 74 flow back to oil supplying device; During oil cylinder 2 reverse operations, the flow direction of oil just in time is on very good terms, and does not repeat them here.
From above-mentioned working procedure as can be seen, connect oil cylinder 2 hydraulic fluid port 21 and 22 with trip shaft 7 on oil circuit interface 31 and 32 transport pipe 5 and 6 keep synchronous with flip-arm 1 all the time, the transport pipe 5 and 6 of the Xie Jueing phenomenon that is stretched and twists fundamentally, so just make transport pipe 5 and 6 just can use for a long time and do not leak, thereby guaranteed the proper functioning of oil cylinder 2.
