Description
Technical field
The utility model belongs to hydraulic nut experimental technique field, and in particular to a kind of hydraulic nut pressure integrity test work
Dress.
Background technology
At present, the pressure integrity test frock used to hydraulic nut is the structure type of steel plate framework integral solder, liquid
Pressure nut hang in hang out it is very cumbersome, and during bulge test uncontrollable piston ring ejection height, easily cause work
Dress deformation, causes piston ring to deform therewith impaired.In pressure maintaining period, the oil leak situation around observation piston ring is also very inconvenient.
In addition, the frock of frame welding is after multiple pressure test is born, there is crackle in weld seam, influences the accurate of pressure integrity test
Property.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, is easy to assembly and disassembly, be difficult by
Damage deformation, and the high hydraulic nut pressure integrity test frock of pressure integrity test precision.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
Hydraulic nut pressure integrity test frock, including top board, lower platen, the first screw rod and hydraulic pump, top board and
Lower platen is be arranged in parallel, and hydraulic nut is located between top board and lower platen, the upper surface of top board and the lower surface of lower platen
Be equipped with some crisscross the first gussets and the second gusset, the first screw flight portion sequentially pass through lower platen center,
It is provided with the first nut behind the center of the screwed hole of hydraulic nut and top board, the ambient separation of the first screw rod is provided with least three the
Two screw rods, the second screw flight portion, which sequentially passes through to be provided with after lower platen and top board on the second nut, top board, is provided with through hole,
The oil pipe of hydraulic pump is connected after passing through through hole with the oil filler point of hydraulic nut.
The head of second screw rod is fixed on lower platen by the 3rd screw rod.
First gusset and the second gusset are welded as a whole with top board, lower platen.
Compared with prior art, the utility model has the advantages that：Frock of the present utility model uses assembled structure,
It is easy to dismounting, ensures that the piston ring ejection height of hydraulic nut is consistent by adjusting nut, can effectively prevent piston ring and work
Dress is impaired, and is easy to observe oil leak situation, can meet the leakage test requirement of different size and thickness hydraulic nut.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model；
Fig. 3 be in Fig. 2 A-A to structural representation.
Wherein, 1, hydraulic nut, 2, top board, 21, through hole, 3, lower platen, the 4, first gusset, the 5, second gusset, 6,
One screw rod, the 61, first nut, the 7, second screw rod, the 71, second nut, the 8, the 3rd screw rod, 9, oil pipe, 10, hydraulic pump.
Embodiment：
As shown in Figure 1 to Figure 3, hydraulic nut pressure integrity test frock, including top board 2, lower platen 3, the first screw rod 6
With hydraulic pump 10, top board 2 and lower platen 3 are be arranged in parallel, and hydraulic nut 1 is located between top board 2 and lower platen 3, top board 2
Upper surface and the lower surface of lower platen 3 be equipped with some crisscross the first gussets 4 and the second gusset 5, the first screw rod 6
Threaded portion is provided with the first nut 61 after sequentially passing through the center of the center of lower platen 3, the screwed hole of hydraulic nut 1 and top board 2,
The ambient separation of first screw rod 6 is provided with least three second screw rods 7, is 8 in the present embodiment, the threaded portion of the second screw rod 7 according to
Secondary pass through is provided with the second nut 71 after lower platen 3 and top board 2, the second nut 71 should be located at the first gusset 4 and the shape of the second gusset 5
Into grid in, be provided with through hole 21 on top board 2, the oil pipe 9 of hydraulic pump 10 passes through the oil filler point after through hole 21 with hydraulic nut 1
Connection.
The screwed hole of hydraulic nut 1 is aligned after the first screw rod 6 is hung on lower platen 3 and installs top board 2, then using first
The nut 71 of nut 61 and second locks hydraulic nut 1 top board 2 and lower platen 3, and oil pipe 9 passes through the through hole on top board 2
21 connect the oil filler point on hydraulic nut 1 with hydraulic pump 10, and hydraulic oil is injected into hydraulic nut 1 by hydraulic pump 10
In, the piston ring jack-up of hydraulic nut 1, the holding situation of pressure is observed by the pressure gauge on hydraulic pump 10, is judged with this
The sealing property of hydraulic nut 1.
During bulge test, ensure the top of hydraulic nut 1 by way of adjusting the first nut 61 and the second nut 71
The ejection height of piston ring is consistent, prevents that piston ring and frock are impaired with this.In pressure maintaining period, hydraulic pressure spiral shell is irradiated with flashlight
Female 1 upper surface and the bonding position of top board 2, can clearly, easily observe the oil leak situation around piston ring, disclosure satisfy that
Different size and the requirement of the leakage test of thickness hydraulic nut.
After the completion of experiment, hydraulic nut 1 can be hung out after taking out the first nut 61, the second nut 71 and top board 2, significantly
Operation is simplified, it is wider using scope.The head of second screw rod 7 is fixed on lower platen 3 by the 3rd screw rod 8, is conducive to carrying
The harmony of the high all-round pressure of first screw rod 6.First gusset 4 and the second gusset 5 are welded as one with top board 2, lower platen 3
Body, makes the overall bearing capacity of frock stronger.
