Description
Technical field
The invention discloses a kind of hole blocking method, specifically a kind of bulging hole blocking method of mechanical hole belongs to mechanical engineering technical field.
Background technique
Because of the needs of technologies such as processing, measurement, assembling, usually many auxiliary holes are set on the component of motor, as engine cylinder-body, oil sump, bent axle etc.Motor when assembling, need seal these auxiliary holes with plug, guarantee that machine oil is not revealed and the normal circulation of fuel feeding, to avoid the damage of the engine component that dry friction causes.
At present, Chang Yong plug has that taper is stifled, steel ball, screw thread stops up and type such as Bowl Plug., steel ball stifled for taper and Bowl Plug, the hole blocking method of shutoff machinery hole in piece part typically uses iron hammer plug is hammered into shape in the auxiliary hole.Stop up for screw thread, during plug-hole, on stopping up earlier, be coated with sealer, with screw-driver it is screwed in the hole then.Above-mentioned two kinds of methods mainly rely on manpower and workman's experience, be not specifically designed to the instrument that plug is installed, thereby labor intensity is big, easily make operator's fatigue, tired back operation will have a strong impact on installation quality, in addition, adopt the said method plug-hole also to injure workpiece easily, be unsuitable for production line operation in enormous quantities, the reliability of installation efficiency and plug-hole is all not high.
Above-mentioned traditional hole blocking method relies on bigger to a great extent to manpower, the quality of plug-hole is wayward, is easy to generate leakage problem, and the leak-down rate of plug-hole is generally about 100PPM.In addition, the tradition hole blocking method also high to the requirement of tolerance of size, roughness and the cylindricity in mechanical hole, these two kinds of hole blocking methods require the tolerance in mechanical hole need be controlled at ± 0.01 in, roughness is less than Ra1.6, cylindricity correspondingly will increase the processing cost in hole less than 0.02.
Summary of the invention
At the deficiencies in the prior art, the object of the present invention is to provide a kind of plug-hole reliable in quality, reduce labor intensity, the efficient bulging hole blocking method in mechanical hole fast is installed.
For achieving the above object, following technological scheme is adopted in the invention: a kind of bulging hole blocking method of mechanical hole, it is characterized in that using the plug and the plug filling rifle that match with hole shape, described plug is made up of steel nail and aluminium cover, described steel nail end is provided with seal ring and locking trough, the neck place is provided with annular and breaks groove, and the concrete steps of plug-hole are as follows:
(1) steel nail puts the aluminium cover, and is pulled to the head of steel nail, and the aluminium cover matches with the seal ring of steel nail end;
(2) the steel nail bar inserts in the gun barrel of filling rifle, regulates the vacuum valve of filling rifle, is held until steel nail;
(3) the steel nail head places in the hole together with the aluminium cover, the end face in aluminium cover outer and hole;
(4) muzzle withstands aluminium cover end face, and the nail bar in the cocking, gun barrel is subjected to air pressure, makes the drawing backward of nail bar, and the aluminium cover is fitted aluminium cover and empty inwall by the outside distending of steel nail head tension and compression;
When (5) steel nail was drawn to certain load, the nail bar was extracted with the filling rifle breaking the fracture of groove place.
Described plug is provided with annular anti-slip tank in steel nail bar portion periphery, and the groove of breaking of plug is positioned within the aluminium cover outer.
Described plug filling rifle is a pneumatic gun, and by compressed air-driven, its rifle head is the claw shape.
Scheme compared to existing technology, beneficial effect of the present invention is:
1, this hole blocking method is simple to operate, and the installation efficiency height is time saving and energy saving, and it is big to have solved traditional hole blocking method installation labor intensity effectively, inefficient problem;
2, the plug that uses this hole blocking method to install, the sealed against leakage performance is good, and leak-down rate is controlled at 5PPM or following, is far smaller than the leak-down rate of traditional hole blocking method;
3, this method has reduced the requirement of roughness, cylindricity and tolerance of size to the hole, can simplify the processing technology in hole, cuts down finished cost.

Embodiment
A kind of mode of execution below in conjunction with 1 ~ 6 pair of bulging hole blocking method of the present invention of accompanying drawing is described further:
The used plug of bulging hole blocking method of the present invention is made up of steel nail 01 and aluminium cover 02, end seal ring 05 and locking trough 04 at steel nail 01, the neck place is provided with annular and breaks groove 03, and plug is provided with annular anti-slip tank 06 in steel nail bar 011 periphery, and described plug matches with the shape in mechanical hole 2.The instrument that plug is installed is the plug filling rifle 10 by compressed air-driven.
A kind of specific operation step of bulging hole blocking method of mechanical hole is:
1) steel nail 01 is put aluminium cover 02, and be pulled to the head of steel nail 01, aluminium cover 02 matches with the seal ring 05 of steel nail 01 end, installs aluminium and overlaps 02 plug structure as shown in Figure 1, and the groove 03 of breaking of plug is positioned at aluminium and overlaps within 02 outer;
2) as shown in Figure 2, steel nail bar 011 is inserted in the gun barrel 11 of filling rifle 10, regulate gun barrel 11 internal air pressure sizes by the vacuum valve of filling rifle, held until steel nail 01, no matter the direction of filling this moment rifle how, plug all can not drop out gun barrel, therefore can satisfy the plug-hole assembling of any direction;
3) as shown in Figure 3, steel nail head 012 is positioned in the mechanical hole 2 together with aluminium cover 02, aluminium overlaps the end face in 02 outer and hole 2;
4) as shown in Figure 4, withstand the end face of aluminium cover 02 with muzzle, cocking, under the effect of the tensile force f that pressurized gas produces, the nail bar 011 in the gun barrel 11 is by tensile force f drawing backward, tensile force f corresponding to moment, can produce a reaction force f forward simultaneously, described reaction force f exerts pressure to aluminium cover 02, and aluminium cover 02 is subjected to the extruding of this power in the outer, right side, meanwhile, aluminium cover 02 in the left side by 012 tension and compression of steel nail head.Because both sides are pressurized simultaneously, aluminium cover 02 outside distending, thus tightly fit with the inwall in mechanical hole 2;
5) as shown in Figure 5, when steel nail 01 was drawn to certain load by tensile force f, nail bar 011 was extracted with the filling rifle breaking the fracture of groove 03 place, finishes the shutoff in mechanical hole 2 thus.
Bulging hole blocking method of the present invention is simple to operate, can realize fast blocking-up, guarantees the plug-hole q﹠r simultaneously, the plug that adopts this hole blocking method to install, its sealed against leakage performance is good, and leak-down rate is controlled at 5PPM or following, is far smaller than the leak-down rate 100PPM of traditional hole blocking method.Method of the present invention has reduced the technological requirement to mechanical hole, and only the tolerance of size that needs control hole is in ± 0.3, and roughness is less than Ra6.3, and cylindricity gets final product less than 0.2, can remove manufacturing procedures such as fraising or tapping fully from.
Be understandable that above-mentioned mode of execution only is the more representational example of the present invention.Obviously, technological scheme of the present invention is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
