Example two
As shown in fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, and fig. 9, a seeker adjusting method according to an embodiment of the present invention employs a seeker adjusting mechanism according to a first embodiment, and includes the following steps: determining an initial adjustment size, and assembling a seeker adjusting mechanism; measuring and calculating the position deviation of the product position marker and the axis of the hood; according to the position deviation, calculating the preset adjusting sizes of two adjusting components 003 which are opposite along any diameter direction of the outer cylinder 001; the adjustment assembly 003 is adjusted to a predetermined adjustment size and the seeker adjustment mechanism is reassembled.
Specifically, before the structural member is assembled, the following dimensions need to be measured accurately: a. The a3 ，A c3 ，A 2 And A 4 Wherein: a. The a3 A length dimension of one of the slider portions 321 distributed in the first diameter direction X; a. The c3 Is the length dimension of the other slider portion 321 distributed in the first diameter direction X; a. The 2 The inner diameter of the frame 002 in the first diameter direction X, in other words, A 2 The spacing of the two opposing mounting planes 201; a. The 4 The inner diameter of the outer tube 001 in the first diameter direction X.
Referring to the size chain shown in fig. 8: a. The 01 ＝A 4 -A 2 +A a1 +A c1 -A a3 -A c3 As shown in fig. 4, 5 and 8, a closed ring a 01 Is a gap between the outer frame and the sliding block, A a1 A thickness dimension, A, of one of the pads 310 distributed along the first radial direction X c1 Is the thickness dimension of the other spacer 310 distributed along the first diameter direction X.
If there is a gap (or interference) between the frame 002 and the first connecting member 320, the structural members such as the outer barrel 001 will deform after the first connecting member 320 and the second connecting member 330 are fastened (screwed) to generate internal stress, so as to counteract the gap (or interference). In order to minimize the internal stress deformations of the structural member, it is considered to compensate this clearance value to zero by compensating rings, i.e. varying the thickness dimension of the shim 310, i.e. let A be 01 =0, may obtain: a. The a1 +A c1 ＝A a3 +A c3 +A 2 -A 4 ＝A * And thus the required total thickness of the gasket (A) a1 +A c1 ). After the gap is compensated, the accuracy of the gap depends on the measurement accuracy of the structural part and the thickness machining accuracy of the gasket, and compared with a common scheme, the gap compensation method is higher in accuracy and lower in machining cost.
According to formula A a1 +A c1 ＝A a3 +A c3 +A 2 -A 4 ＝A * The total thickness of the two spacers 310 in the first radial direction X can be calculated, and thus, the thickness of the single spacer 310 is measured as
And selecting a corresponding gasket 310 according to the calculated thickness dimension of the gasket 310, and assembling the product, wherein the thickness dimension of the gasket 310 at this time is the initial adjustment dimension. After the assembly is finished, according to the imaging quality of the product, the deviation value between the lens and the axis of the head cover can be measured through the optical parameters of the lens and the head cover, namely the position deviation of the product position marker and the axis of the head cover
As shown in fig. 1, 2, 4, 5, 6, 7, and 9, analyzing the deviation between the index and the hood 006 is known: a. The 02 ＝A 6 +A 7 +A 8 +A c1 -A c3 -A 5 Closed ring A 02 Is the deviation between the optical axis of the position marker and the head cover 006, A 6 The dimension of the distance between the axis of the head cover 006 and the mating surface of the head cover 006, A 7 Is the assembly clearance value, A, between the head cover 006 and the outer cylinder 001 8 Is a deviation value A of the mating surfaces of the outer cylinder 001 and the head cover 006 and the mating surfaces of the outer cylinder 001 and the first connecting member 320 in the first diameter direction X c1 The thickness dimension, A, of the spacer 310 in one of the first radial directions X c3 The length dimension, A, of the slider portion 321 of the first connecting member 320 for engaging with the spacer 310 5 The dimension between the axis of the indexer and the mounting plane 201. For a single product, dimension A 6 ，A 5 ，A c3 ，A 8 The size of the structural member is a fixed value. After the assembly of the head housing 006 and the outer tub 001 is completed, a 7 Also a fixed value. At a certain thickness
The gasket 310 is assembled, the product is electrified after the assembly is completed, the imaging quality of the product is tested, and through the optical parameters of the lens and the hood 006, the deviation value between the axis of the lens and the axis of the hood 006, namely the position deviation between the product marker and the axis of the hood 006, can be measured
Further, it can be found that:
if A is to be made 02 =0, then the required spacer thickness is:
i.e., the initial thickness of the shim 310 minus the initial positional offset of the index from the axis of the hood 006.
In the first radial direction X, another padThe thickness of the sheet 310 may be according to the following formula
Derivation is performed to obtain:
that is, the spacer 310 requires a thickness of its initial thickness plus the initial positional offset of the index from the axis of the hood 006. After the thickness dimensions of the two spacers 310 in the first diameter direction X are determined, at this time, the thickness dimensions of the spacers 310 are the preset adjustment dimensions, the spacers 310 are newly selected according to the thickness dimensions, and the product is reassembled, so that the position of the frame 002 in the first diameter direction X with respect to the outer barrel 001 can be adjusted. The position adjustment of the frame 002 with respect to the outer cylinder 001 in the second diameter direction Y is the same, and therefore, the description thereof is omitted. First diameter direction X is perpendicular with second diameter direction Y, makes the regulation mutual noninterference of two directions from this to the staff can carry out the regulation work of two directions simultaneously, and then shortens the regulation duration that makes the position marker and hood 006 adjust well.
