Detailed Description
As shown in fig. 2 to 5, a double-station hydraulic fixture comprises a bottom plate 1, a flange is arranged on the side surface of the bottom plate 1, two positioning seats 2 which are reversely arranged and used for placing a part 3 are arranged on the bottom plate 1, two ends of the two positioning seats 3 are respectively provided with a large positioning pin 31 and a small positioning pin 32 which correspond to a large through hole and a small through hole of the part 3, the outer sides of one ends, close to the large positioning pins 31, of the two positioning seats 3 are respectively provided with an outer jacking mechanism, the side wall of the part 3 is jacked up by the jacking mechanism, a lower pressing plate 4 is further arranged between the two positioning seats 2 and at the position corresponding to the small positioning pin 32, and the lower pressing plate 4 is in power connection with a lower pressing hydraulic cylinder 5 on the bottom plate 1, wherein the lower pressing hydraulic cylinder 5 adopts a CHTB-SD25X20N oil cylinder. During operation, the two parts 3 are correspondingly placed on the positioning seat 2 respectively, the big positioning pin 31 and the small positioning pin 32 on the positioning seat respectively extend into the big through hole and the small through hole of the parts 3 for internal positioning, the outer side of one end of each part 3 is respectively propped up tightly through the outer propping mechanism, the lower pressing plate 4 is driven by the lower pressing hydraulic cylinder 5 to compress the other ends of the two parts 3, and therefore clamping and fixing are completed, operation is convenient, the two parts 3 can be clamped simultaneously, and efficiency is higher.
Further, the propping mechanism comprises a propping hydraulic cylinder 6 arranged at the lower end of the bottom plate 1, the propping hydraulic cylinder 6 can adopt a CHTB-SD20X10N oil cylinder, a piston rod of the propping hydraulic cylinder 6 extends out of the bottom plate 1 and is hinged with one end of the propping plate 61, opposite L-shaped rotating seats 62 are further arranged on the bottom plate 1 corresponding to the middle position of the propping plate 61, and the rotating seats 62 are rotatably connected with the middle of the propping plate 61 through rotating shafts.
Further, the upper end of the piston rod of the pressing hydraulic cylinder 5 is provided with a connecting block 51, the middle part of the pressing plate 4 is provided with a connecting through hole matched with the connecting block 51, the middle part of the pressing plate 4 is inserted on the connecting block 51 through the connecting through hole and rotationally connected through a penetrating rotating shaft 52, and a gap is formed between the lower end of the connecting part of the pressing plate 4 and the connecting block 51 and the lower end of the connecting block 51, namely the height of the connecting part between the lower end of the pressing plate 4 and the connecting block 51 is higher than that of the lower end of the connecting block 51. During operation, the hydraulic cylinder 5 is used for driving the lower pressure plate 4 to press the end part of the part 3, and meanwhile, as the height of the joint of the lower end of the lower pressure plate 4 and the connecting block 51 is higher than that of the lower end of the connecting block 51, the lower pressure plate 4 can have a tiny rotation amplitude relative to the connecting block 51, so that the abnormal clamping with the part 3 can be avoided.
