Abstract
The utility model provides a rocker arm shaft sealing test clamp. The rocker arm shaft sealing test clamp comprises a clamp body, wherein the clamp body has a cylinder-shaped structure, the inner diameter of the clamp body is in matching with the outer diameter of a rocker arm shaft, two ends of the clamp body are identical in structure and are respectively a step hole, bottom portions of the step holes are provided with an O-shaped ring respectively, the inner diameter of each O-shaped ring is in matching with the outer diameter of the rocker arm shaft, upper portions of the step holes are provided with inner thread, two ends of the clamp body are respectively provided with a first flange disc and a second flange disc which are opposite to the two step holes, the two flange discs and the clamp body are in thread connection, and a side face of the clamp body is further provided with an oil inlet. By arranging the O-shaped rings and felt rings at the two ends of the clamp body, the lubricating oil is prevented from flowing into two ends of the rocker arm shaft from a gap between the clamp body and the rocker arm shaft in a test process, so no force is exerted on a jammed outer portion, and test accuracy is improved. The rocker arm shaft sealing test clamp is convenient to use, has a reasonable structure and provides bases for accurate determination on sealing of the rocker arm shaft.
Description
Technical field
The utility model relates to part fixture field, especially a kind of fixture for rocker arm shaft of automobile engine oil pressure impermeability test.
Background technology
Rocking shaft plays to bear and coordinates the function that guarantees that rocking arm runs well and rocking arm is lubricated simultaneously with rocking arm in engine, wherein the lubricating function of rocking shaft mainly provides lubricating oil by the oil duct of rocking shaft inside, for guaranteeing the reliable and stable of oil pressure, need to the two ends of rocking shaft, seal with stopping up.The quality of rocking shaft sealing directly affects the performance of engine, requires to be blocked in after assembling the leakage of oil that can not come off under certain oil pressure effect, therefore the detection of rocking shaft sealing is just seemed to particularly important.
For guaranteeing quality and the efficiency of rocking shaft sealing propertytest, need the actual working state of simulation rocking shaft in engine in advance to test it, during test, need to there is a kind of fixture to clamp rocking shaft.At present, also do not have a kind of fixture in rocking shaft impermeability test, effectively to be applied, it is in producing, to need a difficult problem for solution always.
Summary of the invention
For improving rocking shaft impermeability test efficiency, reduce labour intensity, the utility model proposes a kind of fixture for motor rockshaft oil pressure impermeability test.
For this reason, the technical solution of the utility model is: a kind of rocking shaft tightness test fixture, comprise chuck body, described chuck body is cylindrical structure, and the external diameter of its internal diameter and rocking shaft matches, and it is characterized in that: the two-end structure of chuck body is identical, be a stepped hole, in the bottom of stepped hole, be provided with an O type circle, the internal diameter of O type circle and the external diameter of rocking shaft match, and the top of stepped hole is provided with internal thread; Two ends in chuck body are respectively equipped with the first ring flange and the second ring flange with respect to stepped hole, between two ring flanges and chuck body, are threaded; Side in chuck body is also provided with an oil-in.
A kind of improvement to technique scheme is: convenient and strength-saving when ring flange is rotated, in the side of described the first ring flange and the second ring flange, be respectively equipped with screw.
The another kind of technique scheme is improved and is: for making sealing effectiveness better, be respectively equipped with a felt collar in the stepped hole at described chuck body two ends, felt collar is close to the outside of O type circle, and the internal diameter of felt collar and the external diameter of rocking shaft match.
Using method:
During use, the oil-in in chuck body is connected with oil press joint, takes off the first ring flange, and loosening the second ring flange, make the O type circle corresponding with the second ring flange in free state; Then the rocking shaft that is equipped with obstruction is packed in chuck body, make the inner face laminating of rocking shaft and the second ring flange, the screw rotating on the second ring flange is fitted the outer face of the second ring flange and chuck body, O type circle is compressed simultaneously; Finally the first ring flange is loaded in chuck body and is tightened; Start oil press, by the oil-in in chuck body, to rocking shaft, input lubricating oil.Continue for some time rear fuel cut-off, take out rocking shaft, by checking that whether obstruction place comes off or leakage of oil, judges the sealing of this rocking shaft.
Beneficial effect:
The utility model, by O type circle and felt collar being set at chuck body two ends, prevents that in process of the test, lubricating oil flows to the two ends of rocking shaft from the gap between chuck body and rocking shaft, thereby guarantees that the outside of stopping up does not stress, and improves the accuracy of test with this.This fixture, easy to use, rational in infrastructure, for the accurate judgement of rocking shaft sealing provides foundation.
Accompanying drawing explanation
Fig. 1 is the utility model assembly structure schematic diagram;
Fig. 2 is the structural representation of part 7 in Fig. 1;
Number in the figure is: 1, chuck body; 2, oil-in; 3, O type circle; 4, felt collar; 5, the first ring flange; 6, the second ring flange; 7, rocking shaft; 8, stop up; 9, oil duct; 10, screw.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of rocking shaft tightness test fixture, comprises chuck body 1, and chuck body 1 is cylindrical structure, and its internal diameter matches with the external diameter of rocking shaft 7 with test; The two-end structure of chuck body 1 is identical, is a stepped hole, and an O type circle 3 is housed in the bottom of stepped hole, and the internal diameter of O type circle 3 and the external diameter of rocking shaft 7 match, and the top of stepped hole is provided with internal thread; Being equipped with respectively the first ring flange 5 and the second ring flange 6, two ring flanges and chuck body corresponding to stepped hole between, the two ends of chuck body 1 are threaded; In the side of chuck body 1, be also provided with an oil-in 2.
As shown in Figure 1, convenient and strength-saving when ring flange is rotated, in the side of described the first ring flange 5 and the second ring flange 6, be symmetrically installed with respectively two screws.
As shown in Figure 1, for making sealing effectiveness better, a felt collar 4 is housed respectively in the stepped hole at described chuck body 1 two ends, felt collar 4 is close to the outside of O type circle 3, and the external diameter of the internal diameter of felt collar 4 and rocking shaft 7 matches.
During use, the oil-in in chuck body is connected with oil press joint, takes off the first ring flange, and loosening the second ring flange, make the O type circle corresponding with the second ring flange in free state.At the two ends of rocking shaft 7, load onto and stop up 8(as shown in Figure 2), then rocking shaft 7 is packed in chuck body, make the inner face laminating of rocking shaft and the second ring flange, the screw rotating on the second ring flange is fitted the outer face of the second ring flange and chuck body, finally the first ring flange is loaded in chuck body and is tightened.Start oil press, by the oil-in 2 in chuck body, in rocking shaft 7, input lubricating oil, lubricating oil flows to each oilhole (as shown in Figure 2) by the oil duct 9 of rocking shaft 7 inside.Continue for some time rear fuel cut-off, take out rocking shaft, by checking that whether obstruction place comes off or leakage of oil, judges the sealing of this rocking shaft.
The utility model, by O type circle and felt collar being set at chuck body two ends, prevents that in process of the test, lubricating oil flows to the two ends of rocking shaft from the gap between chuck body and rocking shaft, thereby guarantees that the outside of stopping up does not stress, and improves the accuracy of test with this.This fixture, easy to use, rational in infrastructure, for the accurate judgement of rocking shaft sealing provides foundation.
