Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, 2, a kind of big power swelling device based on hydraulic efficiency nut, comprising: base 1, slide block 2, locating bar 3, the cone 4 that rises, axle 5, nut I 6, spring 7, screw 8, pin 9, nut II 10, hydraulic efficiency nut 11, high-pressure pump 12;
Base 1 upper surface is provided with six circumferentially uniform projection portion 1a, the locating bar open holes that vertical direction runs through base 1 it is provided with in projection portion 1a, base 1 central position is provided with axle open holes, and axle 5 is located in axle open holes and is fixed with base 1 by screw 8 and pin 9;
Locating bar 3 quantity is six, and locating bar 3 is located in locating bar open holes and is fixed by nut II 10 and base 1;
Slide block 2 quantity is six, slide block 2 is located at base 1 top and is sleeved on locating bar 3, it may be achieved circumference is slided, and six slide blocks 2 can open simultaneously, the hole slot 2a that slide block 2 lower surface is provided with projection portion 1a coordinates, is provided with in hole slot 2a and the spring 7 of slide block 2 side and joint, 1a side, projection portion;
The cone 4 that rises is inverted positive hecaprismo cone platform, and the cone 4 that rises is located at base 1 top and is sleeved in axle 5, and the cone 4 that rises can slide up and down along axle 5, bores joint outside 4 with rising inside slide block 2;
Nut I 6 be located at rise cone 4 tops and be threaded with axle 5, hydraulic efficiency nut 11 is located at nut I 6 top and is threaded with axle 5, hydraulic efficiency nut 11 is connected with high-pressure pump 12, applying pressure to hydraulic efficiency nut 11 by high-pressure pump 12 makes hydraulic efficiency nut 11 internal cavity produce High Voltage, hydraulic efficiency nut 11 will rise to Shen, two ends, thus promote the cone 4 that the rises cone 4 that makes to rise to move down, then promote slide block 2 tensioner part.
When specifically operating, processed tube kind part is arranged on swelling device, manual type high-pressure pump 12 pressurizes to hydraulic efficiency nut 11, hydro-cylinder and nut it is built-in with due to hydraulic efficiency nut 11, hydro-cylinder is upheld to two ends due to pressure effect, hydraulic efficiency nut 11 one end has and is screwed on the stud of axle 5, owing to the acting hydraulic nut 11 of reverse power will promote the cone 4 that rises to glide along stationary spindle 5, the cone 4 that rises is an inverted positive hecaprismo cone platform, can promote the slide block 2 to slide outside circumference, then slide block 2 with regard to tensioner processed part. Set nut I 6 again after tensioner, it is achieved safeguard protection.
