Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 shows is the schematic diagram of camshaft hole 2 that has oil groove 4 on waiting to detect engine cylinder lid 1, camshaft hole 2 is the semicircle orifice state this moment, oil groove 4 extends along camshaft hole 2's circumference, the one end of oil groove 4 links up the intercommunication with the drill way that lubricating oil hole 3 is located camshaft hole 2 pore wall mutually, the other end of oil groove then opens on the upper end machined surface 10 of camshaft hole 2 one side, plugging device need with lubricating oil hole 3 drill way, oil groove 4 and lubricating oil hole 3 and the effectual sealed shutoff of linking opening homoenergetic on the upper end machined surface 10.
As shown in fig. 2 and 3, the plugging device of the present invention comprises a base 5, a shaft hole rubber ring 7, two end face rubber rings 6, a mandrel 8, and two guide plates 9.
Two terminal surface rubber rings 6 set firmly in the lower extreme terminal surface 51 of base 5 side by side, and every terminal surface rubber ring all has a part bulge in the bulge of base lower extreme terminal surface downwards, and the lower terminal surface coplane of two bulges, and leaves the clearance between two terminal surface rubber rings 6 are whole and the bulge to deformation that produces when extrudeing mutually with shaft hole rubber ring 7 simultaneously takes place mutual interference influence leakproofness.
The axle hole rubber ring 7 suit is on dabber 8, dabber 8 is whole to be the semicircle columnar shape, the whole appearance of axle hole rubber ring 7 is the semicircle columnar shape, constitute and have the rubber ring hole 70 of semicircle columnar shape by dull and stereotyped section 72 and arc section 71 body coupling, make the axle hole rubber ring 7 can be better closely laminated the suit outside dabber 8 through the rubber ring hole 70 of this semicircle columnar shape, and, dull and stereotyped section 72's surface is just exactly that the upper surface is planar, be used for with two terminal surface rubber rings 6 and act on, the surface of arc section 71 is with 2 pore wall assorted cambered surface forms in camshaft hole, be used for pasting with 2 pore walls in camshaft hole and support the effect, and when arc section 71 supports with camshaft hole 2, the whole embedding camshaft hole 2 of rubber ring 7 in, the upper surface of flat board section 72 and the upper end machined surface 10 coplane in camshaft hole 2 both sides.
The mandrel 8 sleeved with the shaft hole rubber ring 7 is positioned right below the base 5, the upper surface of the flat plate section 72 of the shaft hole rubber ring 7 is parallel to the lower end surfaces of the protruding parts, the mandrel 8 can drive the shaft hole rubber ring 7 to relatively slide relative to the two protruding parts under the guiding and limiting effects of the guiding mechanism, so that the flat plate section 72 can be abutted against and extruded or separated from the two protruding parts, when the flat plate section 72 is abutted against and extruded with the two protruding parts, one part of the lower surface of each protruding part is abutted against the upper surface of the flat plate section 72, the other part of each protruding part is positioned outside the range of the upper surface of the flat plate section 72, in order to balance stress, the area size and the shape of the part of the two protruding parts abutted against the flat plate section 72 are symmetrical relative to the central line of the flat plate section 72, the part of the lower surface of each protruding part, which is positioned outside the range of the upper surface of the flat plate section 72, is used for abutting against and extruding the upper end processing surface 10 of the corresponding side of the camshaft hole 2 of the camshaft, both ensure to block the opening that the oil groove is located one side upper end machined surface, can play the balanced action again jointly and reduce the unilateral atress of plugging device. For better and effective sealing of the oil groove opening, it is ensured that the part of the lower surface of the end face rubber ring which is outside the range of the upper surface of the flat plate section 72 is a complete sealing plane.
The two ends protruding out of the shaft hole rubber ring 7 respectively protrude outwards in the radial direction to form a limiting stop shoulder 81 for preventing the shaft hole rubber ring 7 from moving along the axial direction.
The concrete structure of guiding mechanism can be as shown in the figure, 8 axial both ends of dabber outward symmetry be equipped with base 5 through fastening bolt 93 fixed deflector 9 mutually, 8 axial both ends of dabber respectively each screw thread rigid coupling have rather than two guide posts that axial is parallel, every deflector 9 then offers the direction slot hole 91 that is used for wearing to establish guide post 92.
The working principle is as follows: referring to fig. 4, a state a in the drawing shows that when the plugging device is not in contact with the cylinder head 1, a gap is left between the shaft hole rubber ring 7 and the two end face rubber rings 6 above the shaft hole rubber ring 7, and the shaft hole rubber ring 7 does not generate elastic deformation; the whole plugging device moves downwards to a shaft hole rubber ring 7 in a state B to be attached to the camshaft hole 2 and plug the orifice of the lubricating oil hole 3; the state of the plugging device continues to move downwards to a state C, namely the mandrel and the shaft hole rubber ring 7 can be kept still under the action of the guide mechanism, the two end face rubber rings 6 move downwards relatively until one part of each end face rubber ring 6 abuts against and extrudes the flat plate section 72 of the shaft hole rubber ring 7, the other part of each end face rubber ring abuts against and extrudes the upper end machining face 10 on the corresponding side, and the action face of the end face rubber ring on the right side in the drawing, which is positioned outside the range of the flat plate section of the shaft hole rubber ring 7, and the shaft hole rubber ring 7 cooperate with each other to plug a connecting opening on the oil groove 4 and the upper end machining face 10; and the pressure transmitted by the end face rubber ring 6 enables the shaft hole rubber ring 7 to better plug the orifice of the lubricating oil hole 3. Because the axle hole rubber ring 7 can be wholly embedded into the camshaft hole 2, the upper surface of the flat plate section 72 is parallel to or coplanar with the upper end processing surfaces 10 at two sides of the camshaft hole 2, and the upper surface of the flat plate section is only extruded by the elastic component of the end face rubber ring instead of the rigid component, thereby avoiding the shearing influence of sharp corners formed by the intersection of the upper end processing surfaces and the hole wall on the axle hole rubber ring 7, effectively prolonging the service life of the axle hole rubber ring 7, and realizing tight sealing of the side end of the opening above the oil groove under the elastic extrusion matching of the axle hole rubber ring and the corresponding surface rubber ring.
After the detection is finished, the state C is changed to the state B and then changed to the state A, namely, the plugging device is lifted upwards, firstly, under the common elastic action of the self gravity of the mandrel, the guide mechanism, the end face rubber ring and the shaft hole rubber ring, the end face rubber ring 6 is separated from the upper end processing surface 10 of the cylinder cover and the shaft hole rubber ring 7, the extrusion deformation of the shaft hole rubber ring is reduced, the lifting is continued, the shaft hole rubber ring is separated from the cylinder cover, and the shaft hole rubber ring can completely recover to the initial state.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
