The base and guiding mandrel are set in integral type.
The center of the guiding mandrel and base offers lightening hole vertically, and lightening hole is through hole.
The external diameter of the guiding mandrel is identical with the diameter of axis of guide mating holes.
Compared with prior art, the present invention is arranged oil sealing using Oil seal pressure head, and press fitting oil is treated using locating guide device
The part of envelope is fixed, and axis of guide mating holes is opened up in Oil seal pressure head, and guiding mandrel stretches into axis of guide mating holes and is arranged oil sealing
Pressure head, ensure that the coaxial of Oil seal pressure head, part and guiding mandrel, after forcing press pressure, locating guide device by part and
Oil seal pressure head keeps concentric, can ensure that oil sealing and the concentric oil sealing of part be not crooked during press fitting, it is crooked to avoid oil sealing
Problem causes oil sealing the trimming during press fitting the problem of.
Further, it is spacing to oil sealing using positive stop lug boss, press oil seal pressing when on part, avoid in forcing press
The problem of oil sealing excessive condensation deforms.
Further, Oil seal pressure head bottom circumferentially offers the anti-boss that collides with, and the diameter of the anti-boss that collides with is less than oil sealing pressure
Headgear sets the diameter at oil sealing position, and the keypoint part that Oil seal pressure head contacts with oil sealing when ensure that press fitting does not collide with, and avoids oil
Envelope pressure head, which collides with, to be caused to scratch oil seal lip, the problem of causing oil seal failure.
Further, when Oil seal pressure head is along guiding mandrel downward actuation, using in steam vent discharge axis of guide mating holes
Air, reduction action resistance, facilitate press fitting.
Further, Oil seal pressure head is interference fitted with oil sealing, oil sealing limitation of activity in Oil seal pressure head, more ensure that press fitting
When oil sealing it is not crooked.
Further, some rank positioning spigots are offered according to the size of part on base, part entered using positioning spigot
Row positioning, ensures axiality, has adapted to the demand of different size parts, expands the scope of application of the present invention.
Further, base and guiding mandrel are set in integral type, are easy to process, and improve steadiness, another outer
The center of mandrel and base offers lightening hole vertically, alleviates the weight of locating guide device, is easy to carry.
