Abstract
This application discloses a kind of auxiliary eccentric bush graduating devices, it is made of positioning base, positioning pin, positioning base and detent fit use, and positioning base is identified with eccentric orfice, positioning shaft shoulder, angle groove, and the excircle eccentricity amount of eccentric orfice and positioning base is identical as the eccentricity of eccentric bush；Groove slot carries out 6 equal parts by 0-180 degree；Positioning pin section and end with form, end has non-slip texture, cooperation section and part, positioning base eccentric through-hole are small―gap suture cooperation, positioning pin passes through the eccentric orfice of positioning base and eccentric bush from the bottom to top, keep the eccentric axis of eccentric bush consistent with the axis of positioning base eccentric orfice, carries out groove according to the graduation mark on positioning base end face.
Description
Technical field
This application involves the manufacturing technology field of lining cover parts, especially a kind of graduating device for assisting eccentric bush.
Background technique
It is arranged with leading edge slat in the fixation leading edge of large aircraft at present, is risen by the airplane critical angle of attack is increased
Power.Slat is connect with sliding rail, and is moved under the constraint of the fixed leading edge partition idler wheel of wing along the sliding rail face of leading, realizes slat
Folding and unfolding.For convenience of adjustment slat and fixed leading edge relative position, a kind of eccentric lining is used in the connecting portion of slat and sliding rail
Set adjusts slat and fixed up-front relative position by rotating eccentricity bushing.But due to lining during practical set adjustment
End face non-angular groove mark is covered, can not determine adjusting angle, can only be groped by the experience of manual operator, Wu Faji
Tired data, regulated efficiency are lower.
Since bushing is thermally treated steel part, surface hardness is higher, and liner size is small, and specification is more, uses ruler by hand
Rule method correct error is larger, low efficiency, it is difficult to obtain eccentric axis accurate location.Although using digital control laser groove precision
Height, but equipment manufacturing cost is expensive, the development cycle is long.Therefore need a kind of auxiliary positioning for eccentric bush end face groove and point
Degree, graduating device, both can quickly carry out manual centering, find bushing eccentric axis, while can provide groove indexing reference, auxiliary
It helps scribing cutter to cross, realizes the quick groove of eccentric bush class part.
Innovation and creation content
The application solves its technical problem the technical scheme adopted is that a kind of auxiliary eccentric bush graduating device, by fixed
Position pedestal, positioning pin composition, positioning base and detent fit use, and positioning base is carved with eccentric orfice, positioning shaft shoulder, angle
The excircle eccentricity amount of line mark, eccentric orfice and positioning base is identical as the eccentricity of eccentric bush；Groove slot by 0-180 degree into
6 equal part of row；Positioning pin section and end with form, and end has non-slip texture, and cooperation section and part, positioning base bias are logical
Hole is small―gap suture cooperation, and positioning pin passes through the eccentric orfice of positioning base and eccentric bush from the bottom to top, makes the inclined of eccentric bush
Mandrel line is consistent with the axis of positioning base eccentric orfice, carries out groove according to the graduation mark on positioning base end face.
The application's has the beneficial effect that positioning mechanism structure is simple, easy to use, can be realized by simple manual action
The quick positioning of bushing and according to the direct groove in positioning base end face, and device manufacturing difficulty is low, precision is high, and can meet scene makes
With requiring.With expansibility, different positioning tools can be designed according to the eccentricity of other specification bushings, diameter feature.
Detailed description of the invention
Fig. 1 graduating device operation principle schematic diagram.
Fig. 2 positioning base structural schematic diagram.
Fig. 3 positioning pin stick structural schematic diagram.
Explanation: 1. eccentric bush is numbered in figure；2. positioning base；3. positioning pin；.
Specific embodiment
In order to which the technical features, objects and effects to the application have clearer understanding, Detailed description of the invention the application is now compareed
Specific embodiment.As shown in Figure 1 to Figure 3, the application proposes a kind of auxiliary eccentric bush graduating device, eccentric for aircraft
The device of bushing groove, the device are mainly made of positioning base, positioning pin.
It referring to fig. 2, is the top view of the positioning base 2, the generally revolving body of positioning base 2 makes with the cooperation of positioning pin 3
With, positioning base 2 with eccentric orfice, positioning shaft shoulder, angle groove mark, the excircle eccentricity amount of eccentric orfice and positioning base 2 with
The eccentricity of eccentric bush is identical；Groove slot carries out 6 etc. by 0-180 degree and divides
Referring to Fig. 3 positioning pin 3, section and end are formed with, end have non-slip texture, cooperation section and eccentric bush 1,
2 eccentric through-hole of positioning base is small―gap suture cooperation, and positioning pin 3 passes through the bias of positioning base 2 and eccentric bush 1 from the bottom to top
Hole keeps the eccentric axis of eccentric bush 1 consistent with the axis of 2 eccentric orfice of positioning base, according to the scale on 2 end face of positioning base
Line carries out groove.
In an inactive state, positioning base 2 and positioning pin 3, eccentric bush 1 are all in discrete state.In use process
In, eccentric bush 1 is put into from 2 top of positioning base, and adjustment 1 end cap of eccentric bush makes positioning pin 3 be just passed through positioning base 2
1 eccentric orfice of eccentric orfice and eccentric bush, the at this time positioning of eccentric bush 1 are completed, i.e. the eccentric axis of eccentric bush 1 and positioning bottom
The eccentric axis of seat 2 is overlapped, and carries out groove using the groove mark having on positioning base 2.
Claims (1)
1. a kind of auxiliary eccentric bush graduating device, is made of, positioning base makes with detent fit positioning base, positioning pin
With, it is characterised in that the positioning base is with eccentric orfice, positioning shaft shoulder, angle groove mark, eccentric orfice and positioning base
Excircle eccentricity amount it is identical as the eccentricity of eccentric bush；Groove slot carries out 6 equal parts by 0-180 degree；The positioning pin is by matching
Section and end composition are closed, end has non-slip texture, and cooperation section and part, positioning base eccentric through-hole are small―gap suture cooperation,
Positioning pin passes through the eccentric orfice of positioning base and eccentric bush from the bottom to top, keeps the eccentric axis of eccentric bush and positioning base inclined
