Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As Figure 1-Figure 2, a kind of diesel engine oil sealing assistant pressing tool, comprises base 1, press-loading apparatus 2, press mounting bolt 3 and the set bolt 4 for being connected bent axle.
Specifically, described base 1 embeds and is arranged in press-loading apparatus 2, and is connected with press-loading apparatus 2 by hold-down bolt 3.Described base 1 is cylindrical, and its external diameter equals the internal diameter of oil sealing 5, thus can by oil-sealing sleeve not landing on base outer perimeter.Described base 1 is provided with the first set bolt installing hole 11 and the first press mounting bolt installing hole 12.Described press-loading apparatus 2 comprises and press-fits main body 23 and be arranged on the second set bolt installing hole 21 and the second press mounting bolt installing hole 22 press-fiting main body 23 top, and described press-fits main body 23 for hollow cylinder.The described internal diameter press-fiting main body 23 is more than or equal to the external diameter of base 1, thus base 1 can either be embedded be arranged on to press-fit in the groove in the middle of main body 23, can relatively move by press-loading apparatus 2 again.The described periphery press-fited bottom main body 23 is provided with protruding 24.
Further, described is 2 for connecting the set bolt 4 of bent axle, and is symmetricly set on the both sides of press mounting bolt 3 along press mounting bolt 3 central axis.Assistant pressing tool is fixed to crankshaft of diesel engine by the position symmetrical from the both sides of this assistant pressing tool by 2 set bolts, can ensure oil sealing 6 is being pressed in the process of seal mounting hole 5, uniform active force can be produced to oil sealing 5, ensure that each position of oil sealing 5 is press-fit into place.
Further, the first described press mounting bolt installing hole 11 is positioned at the centre of base 1, and is provided with screw thread in the first press mounting bolt installing hole 11.Screw thread in first press mounting bolt installing hole 11, for the press mounting bolt 3 that is threaded.The first described set bolt installing hole 12 is 2, and is symmetricly set on the both sides of the first press mounting bolt installing hole 11 along the first press mounting bolt installing hole 11 central axis.Screw thread is not had in first set bolt installing hole.
The second described press mounting bolt installing hole 21 is positioned at the centre press-fiting main body 23 top, and is provided with screw thread in the second press mounting bolt installing hole 21.Screw thread in second press mounting bolt installing hole 21, for the press mounting bolt 3 that is threaded.The second described set bolt installing hole 22 is 2, and is symmetricly set on the both sides of the second press mounting bolt installing hole 21 along the second press mounting bolt installing hole 21 central axis.Screw thread is not had in second set bolt installing hole 22.
Concrete use procedure of the present utility model is:
(1) press-loading apparatus 2 is enclosed within base 1, makes to press-fit main body 23 and base matched in clearance.
(2) make press mounting bolt 3 successively through the second press mounting bolt installing hole 21 and the first press mounting bolt installing hole 11, pretension press mounting bolt 3, press-loading apparatus 2 and base 1 are fixed together.
(3) oil sealing 5 is enclosed within the outer ring of base 1.
(4) two set bolts 4 are passed the second set bolt installing hole 22 and the first set bolt installing hole 12 respectively successively, and two set bolts are connected by the screwed hole of screw thread with crankshaft of diesel engine end.Thus whole assistant pressing tool is fixed on bent axle.
(5) slowly tightened by press mounting bolt 2, until cannot turn, oil sealing just can all be pressed in seal mounting hole 5.Specifically, in the process of slowly tightening press mounting bolt 2, press mounting bolt 2 can drive press-loading apparatus 2 to move downward.Along with press-loading apparatus moves downward, the outer wall and the protruding meeting that press-fit main body first contact with the oil sealing upper surface being located at base outer perimeter, then promote oil sealing 6 and enter in seal mounting hole 5.By designing the reach of press mounting bolt 3, make, when press mounting bolt 3 is all tightened, just oil sealing 6 to be press-fited in oil-feed seal installation hole 5 completely.
In sum, oil sealing can be press fit in seal mounting hole by the utility model simply accurately, not only ensure that assembly quality, also improves efficiency of assembling.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
