Aircraft manufacturing exists a series of by bushing and axle interference fit, as shown in figure 1, and material property is different
Two kinds of parts assemblies, to together, now cannot carry out Assembly part using common pressing method.
Content of the invention
The purpose of this utility model is to provide a kind of press-loading apparatus for bushing and axle interference fit, for improving part
Qualification rate.
This utility model is realized by technical scheme below: a kind of press-loading apparatus for bushing and axle interference fit,
Including support, base, hydraulic cylinder, sleeve, clip, positioning support, limited block, wherein said support is in " door " font, and it is fixed
On base, the crossbeam of described support is provided with hydraulic cylinder, hydraulic cylinder and pump housing drive connection, and the hydraulic stem of hydraulic cylinder passes through and props up
The crossbeam of frame is fixedly connected with the pressing plate, and described sleeve connection is enclosed within outside clip in the underface of pressing plate, described sleeve, sleeve interior
Matched with the external diameter of clip in footpath, described positioning support is arranged on base and is located at the lower section of sleeve, on described positioning support
It is provided with the alignment pin for locating element axle b and the hold down gag for shaft parts b that are fixed and clamped, described limited block is used for covering
Be positioned and shaft parts b that are fixed and clamped on.
Described base is provided with guide rail, and positioning support is slidably connected with base by guide rail.
It is provided with the block for stationary positioned bearing operating position on base or on guide rail one.
Advantage of the present utility model: using the product after this utility model processing, through inspection, high yield rate, the power of product
Learn performance (intensity, wearability) and obtain first mate's lifting, substantially meet the needs in production.
Brief description
Fig. 1 is the structural representation of bushing a and shaft parts b interference fit.
Fig. 2 is the structural representation of press-loading apparatus.
Specific embodiment

A kind of pressing method for bushing and axle interference fit, employs described press-loading apparatus, comprises the following steps:
A () press-fits before, first bushing a is clamped by clip 7, then carry out high-temperature heating to 240 ° of actual temps by part material
Depending on the ductility of material；
When () press-fits b, first shaft parts b are placed in press-loading apparatus, are positioned by positioning support 2 and alignment pin 3, filled by compression
Put 4 fixing；Then clip 7 is installed in shaft parts b together with bushing a, sleeve 11 is enclosed within clip 7 simultaneously；And then will
Limited block 12 is installed in shaft parts b, so that the lower surface of limited block 12 is fitted with the shoulder of shaft parts b；Finally start the pump housing 8,
Make hydraulic cylinder 9 produce the pressure of continuous-stable, clip 7 is pressed, when the lower surface of clip 7 is fitted with the upper surface of limited block 12
When, bushing a is installed in place；
C () press-fits after, lay down load, unclamp block 6, skid off locating support 2, unclamp hold down gag 4, take out to press-fit and complete
Part.
