Abstract
The utility model belongs to the technical field of aviation manufacturing, and particularly relates to a binding-off tool of an aviation self-lubricating bearing. The binding-off tool is of an up-down symmetric structure, and comprises an upper binding-off die, a lower binding-off die and a guide mandrel. The middle of the upper binding-off die and the middle of the lower binding-off die are respectively provided with a through hole, and the through holes are in clearance fit with the guide mandrel. A position, corresponding to an installation groove, of the upper binding-off die and a position, corresponding to the installation groove, of the lower binding-off die are respectively provided with a binding-off convex point. The binding-off tool overcomes the difficulty that a positioning end face of a bearing is vertical to a center of a bearing base hole, and perpendicularity needs to be guaranteed through manual control, the current situation that binding-off operations of the bearing with a deep groove cannot be carried out once bind-off process equipment is completed in binding-off of the bearing is changed, and the problem that binding-off pressure and dwell time cannot be accurately controlled in the prior art is solved.
Description
Technical field
The utility model belongs to the aero-manufacturing technology field, particularly relates to a kind of aviation self-lubricating bearing closing in instrument.
Background technology
Abroad, as some aerospace industry developed countries such as the U.S., France, Germany, Britain, research about the aviation self-lubricating knuckle bearing starts to walk very early, through system research and experiment for many years, now formed the self-lubricating knuckle bearing that can adapt to multiple industry condition and installed and technique for fixing Method and process equipment.China starts late about the research of self-lubricating knuckle bearing, and it is installed with technique for fixing Method and process equipment and still adopts plain bearing to install and fixing process and technological equipment.Compare with external similar technology the difference that still existence is larger, the self-lubricating knuckle bearing mounting technique of especially applying in some leading-edge fields such as Aero-Space is close to blank, and this has become affects China obtains a breakthrough important bottleneck in these fields.
Summary of the invention
Goal of the invention: provide a kind of aviation self-lubricating bearing closing in instrument, the closing in effect in the time of can guaranteeing to install.
Technical scheme: a kind of aviation self-lubricating bearing closing in instrument, for upper and lower symmetrical structure, comprise receiving and press mould 1 and receive and depress mould 3, also comprise a guiding mandrel 2, described receipts press mould 1 and receive and depress the middle through hole that all has of mould 3, with guiding mandrel 2 be matched in clearance, described receipts press mould 1 and receipts are depressed on mould 3 with on mounting groove 4 correspondence positions and are provided with closing in spur 5.
When mounting groove 4 is positioned on bearing 6, the outer closing in face A of described closing in spur 5 and the angle α of vertical center line are greater than the angle β of mounting groove lateral surface C and vertical center line.
When mounting groove 4 is positioned on bearing block 7, the angle γ of described interior closing in face B and vertical center line is greater than the angle theta of mounting groove medial surface D and vertical center line.
Beneficial effect: the utility model has overcome the difficulty that bearing location end face and bearing saddle bore central vertical need control to guarantee its perpendicularity artificially, once changed when bearing closes up bottling technique equipment has manufactured just can't be darker to groove the present situation that closed up of bearing, and solved the problem that in the past can't accurately control big or small and dwell time of closing in pressure.
The accompanying drawing explanation
Fig. 1 is the utility model structure one example structure schematic diagram (band mounting groove type);
Fig. 2 is band mounting groove type of topical enlarged drawing;
Fig. 3 is another example structure schematic diagram of the utility model (band chamfering type);
Fig. 4 is band chamfering type of topical enlarged drawing.
Wherein, 1-receives and to press mould, the 2-mandrel that leads, 3-receives and depresses mould, 4-mounting groove, 5-closing in spur, the 6-bearing, 7-bearing block, the outer closing in face of A-, closing in face in B-, C-mounting groove lateral surface, D-mounting groove medial surface, α-outer closing in face and vertical center line angle, β-mounting groove lateral surface and vertical center line angle, γ-Nei closing in face and vertical center line angle, θ-mounting groove medial surface and vertical center line angle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, refers to Fig. 1 to Fig. 4.
As shown in Figures 1 and 3, a kind of aviation self-lubricating bearing closing in instrument, for upper and lower symmetrical structure, comprise receiving and press mould 1 and receive and depress mould 3, also comprise a guiding mandrel 2, described receipts press mould 1 and receive and depress the middle through hole that all has of mould 3, with guiding mandrel 2 matched in clearance, for receipts being pressed to mould 1, receiving the location of depressing mould 3 and bearing.Described receipts press mould 1 and receive to depress on mould 3 with on mounting groove 4 correspondence positions and are provided with closing in spur 5.At bearing, receive in the pressure process, by brearing bore, locate, will part be closed up be placed on to receive and depress on mould 3, by guiding mandrel 2, receipts being pressed to mould 1 again is placed on part to be closed up, then working pressure equipment presses mould 1 to receipts and evenly applies gradually downward pressure, when pressure reaches scheduled pressure value, the pressurize regular hour, complete the closing in of bearing.
According to mounting groove 4 position differences, bearing is divided into to band mounting groove type and band chamfering type.
As shown in Figure 2, with the mounting groove type, bearing mounting groove 4 is positioned on bearing 6, and corresponding closing in instrument and chamfering type are also different.The difference of described closing in instrument is, be greater than the angle β of mounting groove lateral surface C and vertical center line with the angle α of the outer closing in face A of the closing in spur 5 of mounting groove type closing in instrument and vertical center line, make the bearing outer ring material push to bearing block 7 directions under the closing in active force, bearing 6 is fixed on bearing block 7, reaches fixedly purpose.
As shown in Figure 4, with the chamfering type, bearing mounting groove 4 is positioned on bearing block 7, and corresponding closing in instrument is also different with band mounting groove type.The difference of described closing in instrument is, be greater than the angle theta of mounting groove medial surface D and vertical center line with the angle γ of the interior closing in face B of the closing in spur 5 of chamfering type closing in instrument and vertical center line, make the material on bearing block 7 push to bearing 6 directions under the closing in active force, bearing 6 bag pressures, in bearing block 7, are reached to fixedly purpose.
