Description
Technical field
The present invention relates to a kind of assembly fixture, particularly relate to the assembly fixture that a kind of aero-engine general assembly is used.
Technical background
During the aero-engine general assembly, need on an assembly fixture, carry out.The present assembly fixture of usefulness adopts to be arranged on the general assembly that ground fixing or portable mount support is finished engine mostly.Because the diameter and the length of engine are big, the workman must be by the stair type auxiliary stand when assembling, continuous conversion height, and with assembly and part installing one by one, instrument and the equipment and the parts of assembling usefulness will send down by manually serving, and are very inconvenient.Also there is security hidden trouble in the workman at the enterprising line operate of stair type auxiliary stand, if do not note just easy tumble injury health slightly or break part, has influenced assembling speed and assembly quality.So besides erecting yard part is more, also causes the field management confusion easily.
Summary of the invention
The object of the present invention is to provide a kind of safe ready, on-the-spot clean, liftable ground pit type assembly fixture.
For achieving the above object, the present invention has taked following measure:
The present invention is provided with melt pit at below ground, and elevating mechanism is installed in the melt pit, is connected with hoistable platform on elevating mechanism, and this hoistable platform is provided with an assembly fixture and an auxiliary assembly fixture;
Described elevating mechanism is made up of hoistable platform, base, motor, gear-box, turbine and worm mechanism, screw rod, nut; Hoistable platform is contained on two screw rods with nut sleeve, also is provided with roller and guide rail on it, and the guide rail lower end is fixed on the base; Thereby drive the screw rod rotation assembly fixture on the hoistable platform is moved up and down along guide rail, achieve the above object by the gearbox drive worm and gear.
As a further improvement on the present invention, described elevating mechanism is by the hydraulic pressure guide rail that is fixed on the hoistable platform, the cross slide way on the melt pit base that is fixed on, and high-pressure oil pump, drive motors, fuel tank, two cover support bars, hydraulic actuator, petroleum pipeline are formed; Described two cover support bars, one end is separately fixed on hydraulic pressure guide rail and the cross slide way, and the other end is separately fixed on base and the hoistable platform, and moves up and down with hoistable platform.
As another kind of improvement the of the present invention, described elevating mechanism is by the tooth bar that is fixed on the melt pit wall, and the gear and the drive motors that are fixed on the hoistable platform are formed; Reach the purpose of lifting by the rolling of drive motors driven gear on tooth bar.
For further realizing foregoing invention, described assembly fixture can support the 360 ° of rotations in axle center along it.
The present invention with the advantage that existing assembly fixture is compared is:
1, workman's assembly work environment improves greatly, and workman's every operation all carries out on the ground, has avoided the workman to climb up the trouble that climbs down in assembly work, has eliminated the potential safety hazard in the work.
2, help improving assembly quality, because workman's optimum position operation is on the ground carried out various measurement apolegamys and can be reached higher precision, thereby improved assembly quality.
3, having guaranteed the good environment of assembly yard, is exactly the level land because assembling completion back assembly fixture just enters the underground cover plate that covers, and has eliminated the messy phenomenon that assembly fixture is put in factory building.

The specific embodiment
Embodiment 1
As a preferred embodiment of the present invention, as Fig. 1.Subsurface at factory building is provided with melt pit 14, and lowering or hoisting gear 23 is installed in the melt pit 14, is connected with a hoistable platform 5 on lowering or hoisting gear 23.Said hoistable platform 5 is provided with assembly fixture 2 and auxiliary assembly fixture 3 of an assembling engine, and assembly fixture 2 can support the 360 ° of rotations in axle center along it.Engine pack assembling on auxiliary assembly fixture 3 earlier moves to then on the assembly fixture 2 and assembles with other parts.Described lowering or hoisting gear 23 can be the hydraulic pressure or the mechanical multiple kind of drive, as Fig. 1, Fig. 2, shown in Figure 3.Lowering or hoisting gear 23 among Fig. 1 is by worm-and-wheel gear 9, gear-box 10 and motor 11 are formed, and hoistable platform 5 usefulness nuts 13 are sleeved on two screw rods 12, also are provided with roller and guide rail 6 on the hoistable platform 5, the lower end of guide rail 6 is fixed on the base 8, and this hoistable platform 5 can move up and down along guide rail 6.Motor 11 is connected with screw rod 12 respectively by two cover worm-and-wheel gears 9 after slowing down by gear-box 10 again.When motor 11 work runnings, promptly drive screw rod 12 rotations, nut 13 can not rotate thereupon together, can only move up and down along screw rod 12, so also drives hoistable platform 5 and moves up and down together, and hoistable platform 5 is again with assembly fixture 2 and engine one lifting to be assembled.
Another preferred embodiment of the present invention such as Fig. 2, other structures are constant.Described lowering or hoisting gear 23 is by high-pressure oil pump 15, fuel tank 16, two cover support bars 17, and hydraulic actuator 18 is formed.Be connected with hydraulic pressure guide rail 24 on the hoistable platform 5, an also intrinsic cross slide way 25 on melt pit 14 and base 8, four support bar 17 1 ends of two covers are separately fixed on hydraulic pressure guide rail 24 and the cross slide way 25, the other end is separately fixed on base 8 and the hoistable platform 5, and hydraulic pressure guide rail 24 moves up and down with hoistable platform 5.Drive motors 22 drives high-pressure oil pump 15, and hydraulic oil is transported in the pressurized strut 18, promotes pressurized strut and produces axial displacement, and drive support bar 17 is done two-way moving moves up and down hoistable platform 5.
Assembly fixture of the present invention also can adopt such elevating mechanism, sees Fig. 3.Described lowering or hoisting gear 23 is made up of gear 20, tooth bar 21 and drive motors 22.Intrinsic four tooth bars 21 on the melt pit wall, intrinsic four gears 20 on the hoistable platform 5.Four gears 20 on the drive motors 22 driving hoistable platforms 5 roll on vertically arranged four toothed rack 21 and reach the purpose of lifting.
The workman opened melt pit cover plate 4 when assembly work began, by operating mechanism assembly fixture 2 is raised on the ground from melt pit 14 automatically, when being raised to the height of requirement, fix, the beginning assembly work, hoistable platform 5 and assembly fixture 2 can be dropped to below ground together automatically by operating mechanism after assembly work is finished, cover cover plate 4 the level land.
