The bottom surface 12 of described scuffing of cylinder bore base plate 1 offers the square groove 15 of the square toes 21 that can hold described pull bar 2, and the length direction of described square groove 15 is perpendicular to the length direction of described tie rod hole 11.
Described pull bar base plate 1 and cylinder face bracing frame 3 are axially symmetric structure.
The outline diameter on the face of cylinder, upper end of described pull-rod nut 5 is greater than the outline diameter on the face of cylinder, lower end.
There is protruding round platform 31 at described cylinder face bracing frame 3 middle parts, in this round platform 31, there is heavy hole 32, described thrust ball bearing 6 is arranged in described heavy hole 32, and there is through hole at described cover plate 4 middle parts, and the lower end of pull-rod nut 5 is connected to the upper surface of described thrust ball bearing 6 through this through hole.
The outer ring of described cylinder face bracing frame 3 is provided with cylinder frame 33, and the internal diameter of described cylinder frame 33 is greater than the external diameter of cylinder sleeve of engine.
Described cover plate 4 is installed on described round platform 31.
Gap is left in the bottom surface of the upper surface of described thrust ball bearing 6 and cover plate 4.
Described scuffing of cylinder bore base plate 1 is the scuffing of cylinder bore base plate 1 that 45 steel after modulation treatment are processed into, and described pull bar 2 is pull bars 2 that 45 steel after modulation treatment are processed into, and described cylinder face bracing frame 3 is cylinder face bracing frames 3 that 45 steel after modulation treatment are processed into.
Design principle of the present invention:
Cylinder sleeve 8 is nested in engine body 9, is also provided with three road O RunddichtringOs 10 on the cylindrical of cylinder sleeve 8, and cylinder sleeve 8 is tight fit with engine body 9.
1, scuffing of cylinder bore base plate 1 is to be processed by 45 steel after modifier treatment, and modified object has been position increases its intensity (due in use stressed larger on it), and is processed into multistage ladder 14, can be used for the dismounting of the cylinder sleeve 8 of different cylinder diameters.Be processed with square groove 15(as Fig. 2 at the bottom surface 12 of scuffing of cylinder bore base plate 1), in use propping up the square toes 21 of pull bar 2, prevent that pull bar 2 from rotating in company with pull-rod nut 5; The middle part of scuffing of cylinder bore base plate 1 is processed with the tie rod hole 11 passing through for square bar 2.
2, pull bar 2 is also to be processed by 45 steel after modifier treatment, and rectangular square toes 21 are processed in its one end, and when use, square toes 21 are assemblied in 15 li of the square grooves of scuffing of cylinder bore base plate 1, and the other end processes external screw thread.
3, cylinder face bracing frame 3 is to be processed by 45 steel after modifier treatment, and its Main Function is to be positioned over tie-strut 2 on the cylinder cap face of engine body 9 while using.Process heavy hole 32 in cylinder face bracing frame 3 upper surfaces, for assembling thrust ball bearing 6.Use thrust ball bearing 6 to avoid in the time of rotating rod nut 5 because pull-rod nut 5 directly contacts and produces larger frictional force with cylinder face bracing frame 3 upper surfaces.
4, cover plate 4 is for being assemblied in cylinder face bracing frame 3, and its effect is to block the thrust ball bearing 6 being contained in cylinder face bracing frame 3 holes, prevents that it from dropping out.
5, pull-rod nut 5, for being assemblied in pull bar 2, just can pull out cylinder sleeve 8 sleeve port of engine body 9 by rotating rod nut 5.
Assembling of the present invention:
Thrust ball bearing 6 is put in the heavy hole 32 of cylinder face bracing frame 3, covered cover plate 4, and with bolt 7 holddown plates 4.There is certain gap thrust ball bearing 6 upper surfaces and cover plate 4 bottom surfaces, ensure that thrust ball bearing 6 can flexible rotating.
The present invention dismantles the course of work of cylinder sleeve 8:
1. pass through sleeve port, scuffing of cylinder bore base plate 1 is tilted (because the maximum gauge of scuffing of cylinder bore base plate 1 is greater than the internal diameter of cylinder sleeve 8, after only having inclination, just can put in, as Fig. 3) put into below sleeve port, the square toes of pull bar 2 21 are passed after tie rod hole 11 along the direction of the tie rod hole 11 at the middle part of scuffing of cylinder bore base plate 1, by pull bar 2 half-twists, make the square toes 21 of pull bar 2 be stuck in 15 li of the square grooves of scuffing of cylinder bore base plate 1, the lower surface that while preventing from use revolving pull-rod nut 5, pull bar 2 and then rotates, then the ladder of scuffing of cylinder bore base plate 1 14 is leaned against cylinder sleeve 8 together.
2. the endoporus through thrust ball bearing 6 on scuffing of cylinder bore base plate 1 by the upper end of pull bar 2, scuffing of cylinder bore base plate 1 is positioned on the cylinder cap face of engine body 9, the external screw thread in pull bar 2 upper ends by pull-rod nut 5 rotation sets simultaneously, and tighten pull-rod nut 5, make the upper surface of pull-rod nut 5 lower surfaces near thrust ball bearing 6, strain scuffing of cylinder bore base plate 1, finally by Rotating with Uniform pull-rod nut 5, cylinder sleeve 8 is pulled out to the sleeve port of engine body 9 with spanner.As Fig. 5, when scuffing of cylinder bore base plate 1 is pulled to the inwall of close cylinder face bracing frame 3 by pull bar 2, cylinder sleeve 8 can be pulled out.
Because dismounting cylinder sleeve needs larger power, so all parts except thrust ball bearing 6, all by heat treatment, increase its intensity in this cover instrument; In use, directly contact produce the difficulty that increases pull-out cylinder sleeve 8 compared with large frictional force for fear of lower surface and cylinder face bracing frame 3 upper surfaces of pull-rod nut 5, spy increases a thrust ball bearing 6 betwixt.
Finally should be noted that; above embodiment is only for illustrating technical scheme of the present invention but not limiting the scope of the invention; although the present invention is explained in detail with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement technical scheme of the present invention, and not depart from essence and the scope of technical solution of the present invention.
