Description

Self-lubricating knuckle bearing press-fits positioner

Technical field

The utility model relates to mechanical press mounting equipment, and particularly a kind of self-lubricating knuckle bearing press-fits positioner.

Background technology

The self-lubricating knuckle bearing kind is a lot, be widely used in aviation field, play connection, torsion pass, rotation and act on flexibly, especially the V-type groove of self-lubricating knuckle bearing, requirement be installed in have certain reliability on the part, stability and not coming off, in order to guarantee flight safety; In order to ensure self-lubricating knuckle bearing reliable, stable, do not come off, the measure of taking mostly at present is that the self-lubricating knuckle bearing fixing body is fixed on the lathe, under the effect of revolving force, roll work with special cutter, make it and body is installed is fitted, the processing method of this form can't guarantee that the self-lubricating knuckle bearing axiality requires and roll applying, and the meeting stress is concentrated and cracked.

Press-fit the location needs in order to satisfy band V-type groove self-lubricating oscillating bearing, self-lubricating knuckle bearing press-fits locator and adopts whole press-fit approach, and accurate positioning, applying degree height have guaranteed matching requirements and flight safety.

The utility model content

The purpose of this utility model is to provide a kind of operation of being convenient to, can be accurately to band V-type groove self-lubricating oscillating bearing carry out reliably, stablize, adeciduate accurate press-loading apparatus.

For achieving the above object, self-lubricating knuckle bearing press-fits positioner and is made up of pedestal, screw, low punch, upper punch and guide pillar, be provided with three circular holes that are the equilateral triangle layout at pedestal, three screws with three circular hole symmetries of pedestal are arranged at the low punch bottom, utilize screw that pedestal and low punch are connected into an integral body; All be provided with a circular hole in the center of upper punch and low punch, guide pillar be fitted in the circular hole at low punch center, pedestal, low punch, guide pillar are become one, upper punch is installed on the guide pillar and can moves up and down; Low punch upper end and upper punch bottom are 90 ° of angular shapes along the cutting plane of center line.

Have in the centre, upper end of upper punch that pyramid type is damaged, its position, outer has 30 ° circle type damaged, the upper end that makes upper punch is 90 ° of angular shapes along the section of center line, and damaged angle, the outside, end is that 30 °, inboard damaged angle are 60 °; The upper end shape of low punch and the end shape of upper punch are identical.

It is to design at having V-type groove self-lubricating oscillating bearing that this self-lubricating knuckle bearing press-fits positioner, compared with prior art, have easy to operate, it press-fits product reliability and the high technical characteristic of stability, and production cost is low.

The specific embodiment

Below in conjunction with accompanying drawing the structure that self-lubricating knuckle bearing press-fits positioner is described in further detail:

By Fig. 1, Fig. 2 as seen, self-lubricating knuckle bearing press-fits positioner by pedestal 1, screw 2, low punch 3, upper punch 5, guide pillar 6 is formed, be provided with three circular holes that are the equilateral triangle layout at pedestal 1, its aperture can be Ф 9 ㎜, three screws corresponding with three circular holes of pedestal 1 are arranged at low punch 3 bottoms, utilize screw 2 that pedestal 1 and low punch 3 are connected into an integral body, screw can be selected M8 * 14 for use, all be provided with a circular hole in the center of upper punch 5 and low punch 3, aperture Ф 10～10.015 ㎜, guide pillar 6 is fitted in the circular hole at low punch 3 centers, make pedestal 1, low punch 3, guide pillar 6 becomes one, upper punch 5 is installed on the guide pillar 6 and can moves up and down, and the guide pillar diameter can be Ф 10.019～10.028 ㎜; Low punch 3 upper ends and upper punch 5 bottoms are 90 ° of angular shapes along the cutting plane of center line.

Have in the centre, upper end of upper punch 5 that pyramid type is damaged, its extension position has 30 ° circle type damaged, the upper end that makes upper punch 5 is 90 ° of angular shapes along the section of center line, and damaged angle, the outside, end is that 30 °, inboard damaged angle are 60 °; The upper end shape of low punch 3 and the end shape of upper punch 5 are identical, the wedge angle joint at 90 ° of angles of upper and lower drift is the crimping position, during operation, self-lubricating knuckle bearing 4 is fixed by guide pillar, make its lateral displacement amount can only be in the interstice coverage (gap is strict controlled in the 0.005 ㎜ scope) of guide pillar cylindrical and self-lubricating knuckle bearing endoporus herein, be placed on 22.4 ㎜ size place (see figure 3)s of low punch then, again upper punch is placed on the V groove place of self-lubricating knuckle bearing another side, finishes by forcing press and press-fit the location.

Because self-lubricating knuckle bearing press-fits positioning requirements precision height, bearing to different size, need to adopt the drift of different size specification, make self-lubricating knuckle bearing and press-fit the material that positioner adopts and all select the GB material, machining accuracy must be carried out on request in strictness.
