Description
Technical field
It is more particularly to a kind of to hold support base and its press fitting work for non-parallel face pressure the present invention relates to press-loading process
Skill.
Background technology
In the automotive industry, component is connected by screw bolts with linking for component.Meanwhile also exist between component and component certain
Mutual movement, this just needs be bolted outer, and also there are soft connection.Rubber bushing is the major way of soft link.
In automobile processing technology, press-loading process is one of Main Branches of assembly technology.Press-loading process and other techniques
The main distinction be its positioning form, press fitting workpiece is mainly adopted as self-localization-type.Self-localization-type is exactly by workpiece and pressure
Cooperation between dress hole is positioned, and since rubber bushing and press mounting hole are all circle, it is both concentric circles that this is self-positioning
Positioning.And the upper surface of press mounting hole is as the stop surface of press fitting, supporting surface of the lower surface as press fitting.
In press-loading process, 90 ° of folders are presented with stop surface, supporting surface in workpiece surface, i.e. pressure in the vertical stress of pressure assembling force
Angle.In other words, the stop surface of press mounting hole should be parallel (i.e. press mounting hole upper and lower surface is parallel) with supporting surface.
However, with the execution for dropping this technique, in order to reduce finishing cost, ensureing the position degree and profile of press mounting hole
On the basis of, the finishing of press mounting hole lower surface is eliminated, the lower planes that this has resulted in press mounting hole are not parallel.
Fig. 1 is the schematic diagram of the local size requirement of certain type knuckle in traditional press-loading process.As shown in Figure 1, above and below it
There are 3 ° of angle in face.It is pressed at this in engineering, the upper stop surface of workpiece 10 is from the horizontal by angle, upper pressure assembling force and workpiece
Drift angle is produced between 10, is not orthogonal to workpiece surface, bushing 11 deformation, trimming etc. after by unilateral power is caused, causes product to be pressed
Mass defect.
Current technique is, imitative type block manufacture is carried out according to the non-parallel face, and workpiece is fixed by primary standard, and bearing sleeve is along Y side
To press-in.
The major defect of this technology mode is：
First, since workpiece is cast member foozle, fixture can not corrected altitude deflection error.
2nd, since workpiece support face is undressed, there are angle and the error of height.Produce error after, workpiece support face with
Imitative type block surface is there are the angle (foozle generation) of a very little, surface part single-point stress, workpiece surface meeting during press fitting
There is impression.
3rd, the press fitting deformation of bearing sleeve can be reduced, but this phenomenon (workpiece machining error) can not be eradicated.

Do not interfere.For example, a1=41mm in the present embodiment, a2=49.4mm, a3=7mm, d=18mm.Other workpiece sizes are
On the premise of considering installation dimensions, not workpiece interferes.
Present invention also offers a kind of non-parallel face press-loading process, it is used as described above for non-parallel face press fitting
Lower support base, the non-parallel face press-loading process comprise the following steps：
Readiness：By bushing 30, the press mounting hole of workpiece 10, supporting block 22 central aperture centered on line it is coaxial.
Preloading condition one：Bushing 30 is moved downward along Z-direction by seaming chuck, point contact (such as A points) workpiece 10, workpiece
10 receive the transmission of 30 point contact power of bushing, are moved along Z-direction, until workpiece 10 contacts (at B points) with supporting block 22.Here
Workpiece 10 floats for Z-direction.
Preloading condition two：After supporting block 22 receives the power of the Z-direction of B point transmission, rotate to the supporting surface of supporting block 22
Bottom support surface completely with workpiece 10 overlaps.Here since supporting block 22 and support base 21 are sphere-contact, 22 edge of supporting block
Center of circle C rotates.
Impaction state：After supporting block 22 and workpiece 10 completely attach to, workpiece is along Z-direction stop motion, and bushing 30 is along work
The press mounting hole press-in workpiece 10 of part 10, until bushing 30 is combined with the stop surface of the press mounting hole of workpiece 10.
Preferably, further included in the step of preloading condition two：The center line of supporting block 22 and bushing 30, workpiece 10

According to the description of said structure and technique, the present invention holds support base and its press-loading process for non-parallel face pressure
With following features：
First, workpiece floats in Z-direction, and tradition is fixed.The present invention is floated by Z-direction, can be made up in manufacturing process
Middle workpiece surface is relative to the deviation of A benchmark, and workpiece support face is bonded completely with lower supporting block surface in engineering is pressed into.
2nd, the seaming chuck of bushing and presently used consistent (not shown).
3rd, the bottom support surface of workpiece is contacted with the support base of angle rotatable., will be non-by the rotation of support base angle
Parallel surface and the press fitting angular deviation produced, are modified to the vertical stress of pressure assembling force in workpiece surface.
4th, the angle rotation of lower support base is contacted by spherical between support base and supporting block to reach.It is spherical to connect
Contacting surface contact area is larger, force dispersion, while can produce compound angle change, and it is that may be present can further to make up workpiece
(error Producing reason is probably various, such as positioning datum gap etc., product manufacturing error, chucking position to multi-angle error
Degree etc.).
5th, by the rotation of angle by the differential seat angle of script workpiece upper and lower surface, the angle for being converted into supporting block rotates.It is logical
The rotation of over-angle, supporting block upper surface are bonded completely with workpiece lower surface in press fitting, plane stress.Meanwhile by workpiece
Surface is adjusted to level angle with pressure head angle so that the vertical stress of pressure assembling force is in workpiece surface.
Although the foregoing describing the embodiment of the present invention, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
On the premise of from the principle of the present invention and essence, various changes or modifications can be made to these embodiments, but these are changed
Protection scope of the present invention is each fallen within modification.
