The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
As shown in Figures 1 to 3, a kind of press mounting tool 3 of seal 1, seal 1 is tightly connected with part 2, press mounting tool 3 is for being pushed to the assigned address on part 2 by seal 1, press mounting tool 3 comprises keeper 31, press-fit part 32, drive bolt 33, drive bolt 33 and keeper 31, press-fiting part 32 is threaded connection, drive bolt 33 to press-fit direction setting along seal 1, keeper 31 has the first locating surface 311, press-fit part 32 and there is press-assembling surface 321 and the second locating surface 322, keeper 31 is fixedly connected with part 2, press-assembling surface 321 promotes seal 1 motion, while being press-fit into place, the first locating surface 311 coordinates with the second locating surface 322.
The screw thread that drive bolt 33 and keeper 31, press-fits between part 32 can adopt identical rotation direction, also can adopt rightabout, and preferred, driving the screw thread between bolt 33 and keeper 31 is dextrorotation, and driving bolt 33 and the screw thread press-fiting between part 32 are left-handed.While rotariling actuate bolt 33, press-fit part 32 and move along press-fiting direction with driving bolt 33 integral body, simultaneously because rotation direction is contrary, press-fit part 32 relative to driving bolt 33 to move along press-fiting direction, press-fit the driving bolt 33 precession displacements that displacement is twice that press-fit of part 32; Adopt this rotation direction to meet people's operating habit simultaneously.Driving the screw thread on bolt 33 is trapezoidal thread, and driving the left hand thread 331 of bolt 33 is T14 * 3, and driving the right-handed thread 332 of bolt 33 is T18 * 3.Adopt and drive screw thread transmission effective, motion stabilization.
The outer wall of keeper 31 can partly contact or not contact with the inwall that press-fits part 32, preferably, press-fit part 32 and comprise sidepiece 323 and bottom 324, the inwall of the outer wall of the outer wall of part 2, keeper 31, sidepiece 323 is cylindric, and the outer wall of the outer wall of keeper 31, part 2 coordinates with the inwall of sidepiece 323.Adopt said structure, 31 pairs of keepers press-fit part 32 and have guide effect, make to press-fit process and press-fit part 32 and advance steadily, avoid press-fiting part 32 distortions and make that pressure assembling force branch is inhomogeneous causes damage to seal.
Keeper 31 removably connects with being fixedly connected as of part 2, and keeper 31 can be bolted with part 2.Bolt can only connect keeper 31 and part 2, and with press-fit part 32 and do not contact; Bolt also can contact with press-fit portion and provide guide effect for it.Preferably, keeper 31 is connected with being fixedly connected with by bolt 34 of part 2, and bolt 34 also has polished rod section 341, and the bottom 324 that press-fits part 32 has the through hole 325 coordinating with polished rod section 341.Bolt 34 has not only been realized the fixing of keeper 31 and part 2, also for press-fiting part 32, provides good support and guiding simultaneously.
In order to strengthen the positional accuracy of press mounting tool 3 integral body, can on press mounting tool 3, center location structure be set, preferred, part 2 has locating hole 21, press mounting tool 3 also comprises guide pad 35, and guide pad 35 is fixedly connected with keeper 31, and guide pad 35 coordinates with locating hole 21.The guide pad 35 increasing has the effect that good location is provided for press mounting tool 3 integral body.
The first locating surface 311, the second locating surface 322 can be the planes parallel with press-assembling surface 321, also can be to there is the plane of angle with press-assembling surface 321, can also be arc surface or irregular etc., as long as the first locating surface 311 and the second locating surface 322 are suitable.Preferably, press-fiting part 32, to have the 3rd locating surface 326, the first locating surfaces 311, the second locating surface 322, the 3rd locating surface 326 that fit with part 2 end faces be the plane parallel with press-assembling surface 321.Adopt this structure to be convenient to processing, and can better control the degree of depth that press-fits of seal 1.
The degree of depth that press-fits of seal 1 is that the designated mounting position of seal 1 on part 2 is apart from the distance of part 2 end faces, preferably, the distance=press-assembling surface 321 between the first locating surface 311 and the second locating surface 322 and the distance+seal 1 between the 3rd locating surface 326 press-fit the degree of depth on part 2.The relative dimensions that press-fits part 32 and keeper 31 by control just can guarantee that seal 1 meets the requirements of and press-fit the degree of depth.In embodiment shown in the figure, press-fit depth D=B-C.
Part 2 can be the axial workpiece 2 that needs arbitrarily seal 1 sealing, and for example, part 2 is engine crankshaft.
In conjunction with Fig. 4,5, see, combination tool comprises the press mounting tool 3 of seal 1, and steering tool 4 is installed, and steering tool 4 is installed and is had the endoporus 41 coordinating with the outer chamfering 22 of part 2 end faces.22 laminatings of endoporus 41 and the outer chamfering of bent axle that steering tool 4 is installed guarantee that oil sealing installation process inner edge is not damaged by bent axle fillet surface.
It is the hand-held guide cylinder of the ascending gradual change of external diameter that steering tool 4 is installed, and the minimum place of external diameter is less than seal 1 internal diameter, and external diameter maximum is identical with the large end external diameter of engine crankshaft.
Press-fit front utilization installation guiding accessory seal 1 is manually pushed on bent axle, make the outer face of seal 1 in part 2 inner sides, outer faces; Press-fit after end, be rotated counterclockwise and drive bolt 33 to make to press-fit part 32 reply initial positions, the bolt of outwarding winding, takes off press mounting tool 3.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and be only subject to the restriction of claims, those of ordinary skills can easily modify to it and change, but do not leave essence design of the present utility model and scope.
