The specific embodiment
The described a kind of vacuum fixture that is used for large-scale curved wallboard of Fig. 1 comprises: chuck body and vacuum system two parts, and chuck body is made up of anchor clamps carcass 1, bent pressing plate 2, vertical compression plate 3, flanging piece 4 and sealing cord 5; Vacuum system is made up of vacuum meter 6, vacuum valve 7, current divider 8, vacuum tube 9, vavuum pump 10, filter 11 and vacuum tank 12.
Anchor clamps carcass 1 is the support section and the profile part of whole anchor clamps, and anchor clamps carcass 1 is that casting is after machined formation carcass profile leans on ribs to guarantee the requirement of strength of carcass bottom it.
Anchor clamps carcass profile partial schematic diagram is as shown in Figure 2, and the profile of anchor clamps carcass is a circular arc, and its curvature is with identical by the part curvature of curved surface of clamping; For example; The profile radius is 1675mm in the processing, and thickness is in the wallboard of 16mm gets during profile, and the radius of the anchor clamps carcass profile of design is 1691mm.Be distributed with adsorption area extending bore 13, vacuum tank grid 14, fixing hole 15, vacuum hole 16 and locating hole 17 on the anchor clamps carcass profile.
The rectangle that said vacuum tank grid is the crisscross determining deviation groove that sink; The density of grid reaches according to accessory size to be decided the requirement of adsorption area; The vacuum tank grid not only as vacuum loop, adsorption area but also as seal groove, can be arranged sealing cord according to the wallboard size.
Said locating hole is distributed in the rectangular block of vacuum tank grid formation, and it cooperates a peripheral edge of guaranteeing wallboard to align with anchor clamps carcass profile benchmark with alignment pin; Said fixing hole, vacuum hole, adsorption area extending bore lay respectively in the different rectangular blocks of vacuum tank grid formation.
Vacuum hole is a counterbore, and with the conducting of anchor clamps carcass profile, itself and vacuum valve are through the sealing of O RunddichtringO.When the wallboard size decreases, subsequent use vacuum hole vacuum available silently seals obstruction, on all the other rectangular blocks, has the adsorption area extending bore, can increase adsorption area, and said adsorption area extending bore is communicated with vacuum tank.
Said vertical compression plate 3 is the clamping spare unit with bent pressing plate 2; Possibility resilience after the part roll forming; It is bad that piece surface and anchor clamps carcass profile are fitted; Bent pressing plate 2 can guarantee that part periphery and anchor clamps carcass profile fit, and vertical compression plate 3 prevents warpage in the middle of the part, and bent pressing plate 2 and vertical compression plate 3 are connected with fixing hole on the anchor clamps carcass profile through bolt; Alignment pin realizes that with the locating hole interference fit part aligns with anchor clamps carcass profile benchmark, guarantees machining accuracy on one side; Said sealing cord embeds in the seal groove grid, through different arranging anchor clamps carcass profile is marked off the zone that can control separately.
In order to satisfy the clamping requirement of several kinds of size model wallboards simultaneously, in optimum implementation of the present invention, mesh spacing is 150mm, and the width of vacuum tank is 6mm, and the degree of depth is 4mm.Sealing cord adopts O type resistance oil silicone rubber material, and sealing cord is arranged in the corresponding vacuum tank, and anchor clamps carcass profile is divided into 13 vacuum areas can independently controlling, and it is as shown in Figure 3 that sketch map is divided in the zone.Said vacuum system is communicated with anchor clamps carcass profile through the vacuum valve, and the vacuum valve is a step axle, and the hole is got through in the axle center, anchor clamps carcass profile processing counterbore, and vacuum valve and anchor clamps carcass profile counterbore interference fit, the step place adds a sealing ring and guarantees its sealing.
Vacuum valve and anchor clamps carcass profile are through the sealing of O RunddichtringO; Vacuum tank on the anchor clamps carcass profile is communicated with vacuum source; The vacuum valve through vacuum line successively be fixed on the anchor clamps carcass on vacuum meter 6, vacuum valve 7 be connected, it is connected through vacuum adapter, vacuum tube 9 and the vacuum meter 6 that is fixed on anchor clamps carcass side.Vacuum meter 6 is used for judging the vacuum of each branch road, connects vacuum valve 7 between vacuum meter 6 and the current divider 8, and vacuum valve can be controlled each line state, and current divider 8 is divided into each branch road with total gas circuit so that each regional vacuum of anchor clamps carcass profile is controlled flexibly.The triple valve that current divider 8 and vacuum tank are 12 act as cut-offfing and the vacuum breaker of part processing after finishing of the total gas circuit of control, vacuum tank has the voltage stabilizing cushioning effect.Moisture, greasy dirt and the dust of filter 11 in can the filtering gas circuit.
The vacuum system sketch map is as shown in Figure 4.During clamping, wallboard is put on the anchor clamps carcass profile, wallboard on one side with locating hole in straight pin be close to and guarantee the part processing benchmark, axially both sides compress with said flanging piece 4, prevent along its central shaft rotation.10 pairs of whole vacuum systems of open vacuum pump vacuumize; Stop to vacuumize when requiring when vacuum reaches absorption, be lower than other branch roads, can judge this branch road gas leakage if find certain branch road vacuum; Can the hand valve 18 on this road cut out, in order to avoid influence the vacuum of whole system.The reason that produces this phenomenon possibly be local warpage after the wallboard roll forming, and said bent pressing plate 2, vertical compression plate 3 can be avoided the gas leakage of anchor clamps carcass profile place after compressing.Fit when wallboard curved surface and anchor clamps carcass profile, behind the vacustat, unload vertical compression plate 3, treat the wallboard completion of processing after, said triple valve is pushed the exhaust retaining makes the vacuum system vacuum breaker, unclamp flanging piece 4, unload lower wall panels.
The utility model has carried out special design to anchor clamps carcass profile, vacuum tank and adsorption area, and adopts the vacuum air-channel method of control separately, has solved the problem that large-scale curved wallboard vacuum clamping is difficult to realize.
