The individual sector upper surface of boss i.e. locating surface, now bulb have a upper motion moving 0.3mm, relative, row vertically
Compressing tablet and semicircle compressing tablet have a motion pushing to flange, now produce clamping force.
Operation principle
Discharge bulb is carried out as follows with the installation of this mounting structure.Bulb locating notch and specification identification notch alignment are connect
Installation card base on contact 1 and mistake proofing semicircle compressing tablet are inserted directly on earth, then bulb turn clockwise 25 degree and are installed in place.
Due to screwing in position initial, the underface of the installation card base of contact chip 1 ensconced by the boss on support base, after bulb inserts,
Boss on support base just snaps in the locating notch of bulb, support base will be driven to rotate together, Zhi Daozhi during dextrorotation bulb
On support seat, locating surface is contacted with installation portion locating surface and realizes spacing (limiting X-axis rotary freedom).
During dextrorotation bulb, support base head gradually pushes up to contact compressing tablet 16, because contact compressing tablet 16 and installation portion are
Fixed, when support base is screwed into and is contacted with contact compressing tablet 16, contact compressing tablet 16 has an active force to support base,
It is made to drive bulb by being certainly changed into rotation while mobile.Additionally, for waist-shaped hole at the cooperation of installation portion and bulb flange outside diameter
Structure, two waists play the guiding role, so support base drives bulb along direction rotation while mobile of two waists, until terminating screwing in
Position stops, in termination screw-in position because contact compressing tablet 16 and support base are designed to interference fit, therefore, contact pressure
Piece 16 has an active force to make it withstand on (the restriction Y/Z direction free degree) on V-type face all the time to bulb.
The baseplane of lamp base flange is provided with the anchor point of 3 raised 0.3mm, and bulb inserts installation portion initial position
When, anchor point just soars in groove, and the row pressure piece on contact chip 1 misuses semicircle compressing tablet relative to bulb flange with anti-
Exceed 0.3mm in X negative direction.When bulb screws in, bulb does rotation and linear motion so that 3 anchor points mark groove
And it is positioned on the locating surface of installation portion (limiting X-direction, Y/Z axle rotary freedom), that is, whole bulb is along X negative direction jack-up
0.3mm, simultaneously bulb flange move to a row clamping compressing tablet, mistake proofing semicircle compressing tablet and install card base below, now, clamp compressing tablet
Just it is pressed on flange with mistake proofing semicircle compressing tablet, wherein installing card base is interference fit, and three plays the effect fixing to clamp.
Additionally, when bulb is installed in place, contact chip 17 has individual thrust, direction and contact all the time to the circumference of bulb flange
The thrust direction that compressing tablet 16 provides is substantially opposite, because the thrust design that contact compressing tablet 16 provides becomes to carry much larger than contact chip 17
For thrust, so resultant direction is still all the time towards V-type face it is ensured that positioning is reliable.
Discharge bulb is carried out as follows with the dismounting of this mounting structure.By discharge bulb rotate counterclockwise, 25 degree screw in initial
Position, then extracts bulb.When derotation bulb, contact compressing tablet 16 and support base are gradually disengaged it is meant that contact compressing tablet
The thrust of 16 offers is gradually reduced until the thrust providing less than contact chip 17, under the thrust that contact chip 17 provides, lamp
Bubble drives support base to return to initial insertion position along two waist directions.Now can smoothly extract bulb.
The course of work：Bulb is inserted into the state in mounting structure straight along optical axis direction, and now bulb is in installation just
Beginning position, bulb flange square breach are just coordinated with the boss 12 of support base, and 3 on bulb flange anchor point is in installation
In the inner side slot of the fan-shaped boss in 3, portion.Then turn clockwise bulb certain angle, and now bulb is still in installation initial bit
Put, in rotary course, bulb drives support base rotation together, support base boss 12 gradually removes from the card base 4 of contact chip 1, lamp
Bubble flange is gradually moved under the card base 4 of contact chip 1, and support base pentagon boss 19 is just contacted with contact compressing tablet 16, bulb
3 anchor points on flange are still in installation portion scalloped recess.Then turn clockwise bulb again, now support base 3 and peace
The positive stop lug boss contact of dress portion, bulb is in installation final position, and in rotary course, bulb continues to drive support base to rotate together, with
When support base drive bulb to do translational motion along installation portion spigot surface under the active force of contact compressing tablet 16, although now lamp
Bubble equally receives the opposition of contact chip 17, but the elastic force of contact chip 17 arranges, institute less than the elastic force of contact compressing tablet 16
With under the superimposed motion that translates while in rotation, support base boss 12 removal completely from card base 4, bulb flange is completely moved to card
Under pin 4, bulb flange opposite side moves on under a row pressure piece 6 on card base 4 opposite, and 3 anchor points on flange are from installation portion groove
Have been moved on the locating surface that fan-shaped boss 11-1,11-2,11-3 are constituted, bulb is slightly raised (salient point oneself height) simultaneously
The slightly card base 4 on jack-up contact chip 1 and row pressure piece 6, makes contact chip 1 that bulb is produced with downward clamping force and realizes fixing.Footpath
To direction, under the making a concerted effort of contact compressing tablet 16 and contact chip 17, bulb is withstood on V-type locating surface 14 all the time, thus ensureing
Higher radial positioning precision.
Radial positioning is analyzed
Bulb radial positioning was by whole circumference face internal diameter or part-circular periphery face internal diameter positioning in the past, for the ease of insertion
Bulb, positioning periphery internal diameter and bulb flange be gap coordinate, and bulb in any direction all it may happen that offset, therefore,
Centering precision is poor.This structure adopts V-type face cooperation elastic contact chip positioning, and bulb can only shift in a direction, and
Specially setting circle (face) is amplified to facilitate insertion into bulb without consideration.
Periphery position error
Periphery analysis of Positioning Error.As shown in figure 9, setting circle of position endoporus aperture as D (+Δ D1/- Δ D2), bulb is convex
Edge external diameter is d (+Δ d1/- Δ d2), and for the ease of inserting bulb, the minimum of a value of setting circle internal diameter is than bulb flange outside diameter
Big value is big, and both minimum fit gaps are set to X.(reflecting surface optical centre), lamp with setting circle endoporus center O as positioning datum
Bubble flange center O1 is bulb center, and because setting circle internal diameter and bulb flange outside diameter size have tolerance, and both presence are
Little fit clearance, bulb center relative positioning center is in any direction all it may happen that offset.If setting circle internal diameter accomplishes maximum D
+ Δ D1, bulb flange outside diameter accomplishes minimum d- Δ d2, and now the distance of positioning datum O to bulb center O1 is maximum, maximum positioning
Error is
Δ circle=2*OO1=2* by mistake【(D+ΔD1)-(d-Δd2)】/ 2=D-d+ Δ D1+ Δ d2,
By
X=(D- Δ D2)-(d+ Δ d1) i.e. D-d=Δ D2+ Δ d1+X
?
Δ circle=Δ D1+ Δ D2+ Δ d1+ Δ d2+X by mistake
V-type face position error
V-type face coordinates elastic contact chip analysis of Positioning Error.As shown in Figure 10, if positioning V-shaped face is located, the aperture of circle is D
(+Δ D1/- Δ D2), bulb flange outside diameter is d (+Δ d1/- Δ d2), because this structure positioning face is V-type face, and installation process
Middle bulb center is mobile, therefore both do not have minimum fit gap X.Due to positioning V-shaped face and bulb flange outside diameter size

Line.?
O1A=【(d+Δd1)/2+【(D+ΔD1)-(D-ΔD2)】/2】/sin(α/2)
O2A=【(d-Δd2)/2】/sin(α/2)
Δ V=O1O2=O1A-O2A=(Δ D1+ Δ D2+ Δ d1+ Δ d2)/2sin (α/2) by mistake
Because V-type face angle [alpha] is designed as 90, obtain
Both are relatively more visible, and in terms of position error numerical value, " Δ is justified by mistake " is more than " Δ V by mistake ", in locating bias direction side
Face, and the former is in any direction it may happen that skew, the latter is only in the skew of V-type face above-below direction.
