Base plate, it is arranged on workbench, for placing connecting rod;
Lower gland, it is arranged on base plate and to workbench below and extends, and described lower gland and upper compression leg coaxially arrange;
Fairlead, it is rack-mount, for upper compression leg is led;
The little axle lower end of described upper compression leg is provided with little guide pillar, in described lower gland, is provided with little guide pin bushing, and this little guide pin bushing is for leading to little guide pillar.
Further, the external diameter of described seaming chuck overcoat is greater than the internal diameter in the microcephaly hole that is press-fited connecting rod.
Further, the length of seaming chuck overcoat is less than the length of gland.
Useful technique effect of the present utility model is:
1, connecting rob bushing press mounting die of the present utility model is realized the automatic guiding of upper compression leg and lower gland by little guide pillar and little guide pin bushing are set, guaranteed the concentricity of lining and connecting rod small end hole, make the laminating degree of lining and connecting rod more than 95%, avoid the steel backing of lining by scratch from 85% original raising simultaneously;
2, due to the external diameter of seaming chuck overcoat, be greater than the internal diameter in the microcephaly hole that is press-fited connecting rod, in the process declining at upper compression leg, after bushing press-mounting puts in place, the ramp of the inclined-plane contact connecting rod of seaming chuck overcoat, pressure assembling force is born by connecting rod ramp, lining no longer bears pressure, thereby guarantees that the lower inclined plane of lining can not extrude the lower inclined plane of connecting rod; Simultaneously, because the length of seaming chuck overcoat is less than the length of upper gland, when press-fiting, when the inclined-plane of seaming chuck overcoat contacts the ramp of connecting rod, lining is pressed into completely in the microcephaly hole of connecting rod under the effect of upper gland, the ramp of lining can not exceed the ramp of connecting rod, reaches technological requirement.
3, connecting rob bushing press mounting die of the present utility model is simple in structure, easy to use, has effectively improved product press-fit quality by automatic guide, has saved production cost.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further details.
Fig. 1 is structural representation of the present utility model, and as shown in Figure 1, connecting rob bushing press mounting die of the present utility model, comprising:
Upper compression leg 1, it is multidiameter, the upper end of macro-axis 16 is connected with hydraulic press;
Upper gland 3, it is sleeved on the little axle 15 of compression leg 1, and carries out axial limiting by the cascaded surface of upper compression leg 1;
Seaming chuck overcoat 2, it is sleeved on the outside of gland 3, and carries out axial limiting by the cascaded surface of upper compression leg 1;
Base plate 8, it is arranged on workbench 7, for placing connecting rod 9;
Lower gland 6, it is arranged on workbench 7 and to workbench below and extends, and described lower gland 6 coaxially arranges with upper compression leg 1;
Fairlead 12, it is arranged on support 11, for upper compression leg 1 is led.
As shown in Figure 1, little axle 15 lower ends of described upper compression leg 1 are provided with little guide pillar 4, in described lower gland 6, are provided with little guide pin bushing 5, and this little guide pin bushing 5 is for leading to little guide pillar 4.When press-fiting, along with the decline of upper compression leg 1, little guide pillar 4 is first incorporated in little guide pin bushing 5, thereby by upper compression leg 1 and lower gland 6 automatic guidings, has guaranteed the concentricity of lining 13 with the microcephaly hole 10 of connecting rod 9, has guaranteed laminating degree, has avoided the steel backing of lining 13 by scratch.
As shown in Figure 3, in the present embodiment, the external diameter of described seaming chuck overcoat 2 is greater than the internal diameter in the microcephaly hole 10 that is press-fited connecting rod 9.
As shown in Figure 4, in the present embodiment, the length of seaming chuck overcoat 2 is less than the length of gland 3.
In upper compression leg 1 decline process, after lining 13 is press-fit into place, the ramp of the inclined-plane of seaming chuck overcoat contact connecting rod 9, pressure assembling force is born by the ramp of connecting rod 9, lining 13 no longer bears pressure, thereby guarantees that the lower inclined plane of lining 13 can not extrude the lower inclined plane of connecting rod 9; Simultaneously, because the length of seaming chuck overcoat 2 is less than the length of upper gland 3, when press-fiting, when the inclined-plane of seaming chuck overcoat 2 contacts the ramp of connecting rod 9, lining 13 is pressed into completely in the microcephaly hole 10 of connecting rod under the effect of upper gland 3, the ramp of lining 13 can not exceed the ramp of connecting rod, reaches technological requirement.
It is spacing that connecting rob bushing press mounting die of the present utility model utilizes seaming chuck overcoat 2 to carry out, and cancelled limited block 14 of the prior art, not only makes the structure of mould simpler, also solved the spacing inaccurate technical problem of limited block.
Below in conjunction with accompanying drawing, further illustrate the utility model and press-fit process:
As Figure 1-3, before press-fiting, the microcephaly hole 10 of connecting rod 9 is fixed on lower gland 6, lining 13 is enclosed within on the little axle 15 of upper compression leg 1, the ramp of lining 13 and the inclined-plane of upper gland 3 are fitted tightly.
Then primer fluid press, upper compression leg 1 starts to decline, in this process, as shown in Figure 2, little guide pillar 4, through the microcephaly hole 10 of connecting rod 9, enters in little guide pin bushing 5, thereby by upper compression leg 1 and lower gland 6 automatic alignments, guarantee when lining 13 is pressed into connecting rod 9 microcephaly hole 10 also can align.
As shown in Figure 3, upper compression leg 1 continues to decline, lining 13 starts to enter in the microcephaly hole 10 of connecting rod 9 under the effect of seaming chuck 3, when the inclined-plane of seaming chuck overcoat 2 and the ramp of connecting rod 9 fit tightly, pressure assembling force is born by the ramp of connecting rod 9, and lining 13 no longer bears pressure, and upper compression leg 1 can not continue to move down, lining 13 is pressed in the microcephaly hole 10 of connecting rod 9 completely, and can not exceed the upper lower inclined plane of connecting rod.When pressure assembling force reaches after setting value, hydraulic press unloads power automatic-ascending, completes once and press-fits.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described 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 the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
