Abstract
The utility model discloses a jig that punches for large -scale cyclic annular flange, including jig pedestal, big drill bushing, little drill bushing and rings, rings lie in the front end of jig pedestal, are equipped with big drill bushing and little drill bushing in proper order on the right side of rings, and the right side of little drill bushing is equipped with the fixed position reference surface. Adopting whole location at the during operation, accomplishing the punching of cyclic annular flange through whole with local cooperation is disposable, structurally adopt antifatigue, shock attenuation nature and wearability design, this jig has improved the alignment efficiency of flange on the lathe, has improved the locating speed of drilling, has guaranteed the position degree and the required precision in hole, has also improved equipment reliability of operation and security simultaneously for production efficiency increases substantially.
Description
Technical field
This utility model relates to a kind of mould used in machining, particularly to a kind of punching drill jig for large-scale annular flange.
Background technology
Large-scale annular flange carries out punching and has become as the part that field of machining is critically important, the most domestic in the machining production process of large-sized flange, is essentially all single-piece and directly goes up drilling machine, carries out technological innovation and then improve working (machining) efficiency on drill bit.This processing method only improve only the drilling efficiency of flange, the position degree in hole on flange is the most well improved with required precision, and in actual use, it is more that flange carries out the influence factors such as clamping, the location in hole, turnover, directly result in equipment operating cost high, integral production efficiency is low, the processing request of flange is the highest, the most also to be restricted with the duration by contract quantity, this just requires as producing crucial drill jig, not only to ensure that the large-sized flange of processing meets drawing technology requirement, also to improve working (machining) efficiency greatly；Ensure the permanent use of drill jig self simultaneously, be unlikely to that gross distortion and fatigue rupture occur in a short time.
Utility model content
The purpose of this utility model is: for problems of the prior art, it is provided that a kind of punching drill jig for large-scale annular flange, to improve equipment reliability of operation and safety so that production efficiency increases substantially.
Concrete scheme of the present utility model is:
A kind of punching drill jig for large-scale annular flange, including drill jig pedestal, big drill bushing, little drill bushing and suspension ring, suspension ring are positioned at the front end of drill jig pedestal, are sequentially provided with big drill bushing and little drill bushing on the right side of suspension ring, and the right side of little drill bushing is provided with stationary positioned datum level.Drill jig pedestal, big drill bushing, little drill bushing and suspension ring use entirety location, by overall with locally coordinate the punching disposably completed large-scale annular flange, operationally drill jig pedestal plays fixing, reference for assembling effect, drill bushing plays the role of positioning, and suspension ring undertake gravitational load.
Preferably, drill jig pedestal, drill bushing, suspension ring structurally use resisting fatigue, damping property and wearability design, in order to while improving mould whole structure, improve intensity and the wearability of key position.
Preferably, drill jig pedestal uses casting pig, and tensile strength and plasticity are low, but casting character and damping performance are good.
Preferably, drill bushing uses tight interference fit with jig seat body opening, prevents drill bushing from skidding at short notice, causes drill bushing to scrap.
This utility model hinge structure has the effect that
1 this utility model provides a kind of punching drill jig for large-scale annular flange, drill jig and large-scale annular flange assembly mode is used on population structure, improve flange centering efficiency on lathe, improve the locating speed of boring, ensure that position degree and the required precision in hole, also improve equipment reliability of operation and safety so that production efficiency increases substantially simultaneously.
2, drill jig described in the utility model have the strongest toughness,PlasticityAnd wearability, there is good repeatability.
3, Drilling Jig Structure described in the utility model is simple, easy for installation, and low cost is simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of punching drill jig for large-scale annular flange, including drill jig pedestal 1, big drill bushing 2, little drill bushing 3, suspension ring 4, suspension ring 4 are positioned at the front end of drill jig pedestal 1, are sequentially provided with big drill bushing 2 and little drill bushing 3 on the right side of suspension ring 4, and the right side of little drill bushing 3 is provided with stationary positioned datum level 5.
Drill jig pedestal 1, big drill bushing 2, little drill bushing 3, suspension ring 4 form drill jig overall structure, operationally use entirety location, by overall with locally coordinate the punching disposably completed large-scale annular flange, drill jig pedestal 1, big drill bushing 2, little drill bushing 3, suspension ring 4 structurally use resisting fatigue, damping property and wearability design；Drill jig pedestal 1 uses casting pig, tensile strength and plasticity low, but casting character and damping performance are good；Big drill bushing 2, little drill bushing 3 use 40Cr steel, handling ease, quenched with surface hardening after have the strongest toughness,PlasticityAnd wearability；Big drill bushing 2, little drill bushing 3 use tight interference fit with drill jig pedestal 1, ensure assembling effect and good looking appearance by liquid nitrogen cold charge, and with location, large-scale annular flange 6 hole are carried out Drilling operation according to the size of drill bushing endoporus；Fix and position datum level 5 and ensureing after it assembles with flange on the basis of the dimensional requirement of position, each hole so that drill jig and large-scale annular flange 6 can exchange and be easy to assembling smoothly；Suspension ring 4 structure uses the lifting bolt of the GB/T825-88 meeting national standard, is threaded connection at the balance of drill jig pedestal 1 center, enabling carrying gravitational load, and ensures the balance of drill jig when assembling.
Above-described is only preferred embodiment of the present utility model.Should be understood that for the person of ordinary skill of the art, under technology provided by the utility model is enlightened, as the common knowledge of mechanical field, it is also possible to make other equivalent modifications and improvement, also should be regarded as protection domain of the present utility model.
