The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model mainly is made up of base 14, guide rail 9, guide rail 10, guide rail 11, rail plate 12, rail plate 13, vertical columns 1, adjustable column 2, adjustable column 3, adjustable column 4 and accurate levelling gear 5,6,7,8.Guide rail 9, guide rail 10, guide rail 11 are fixed on the base 14, the bottom at rail plate 13 two ends has the U-shaped chute and is stuck on guide rail 10 and the guide rail 11, can on guide rail 10 and guide rail 11, move continuously, rail plate 12 is positioned at the below of guide rail 9 and rail plate 13, can move continuously along the horizontal direction of guide rail 9 and rail plate 13, rail plate 12 and rail plate 13 can move to satisfy the location requirement of different size backlight framework continuously at the horizontal and vertical of level.All guide rails and rail plate are all processed identical T type groove, and promptly the cross section of guide rail is the T type groove structure, and column with matching and levelling gear can move arbitrarily in T type groove.The stationkeeping of column 1 is motionless, and highly also fixes, and can be used as the reference of other column and levelling gear zero-bit height; Column 2,3,4 adopt the spiral micro-measuring structure to carry out the precision adjustment of vertical direction height, and the adjustment precision is 0.01mm, and four corner angle of backlight framework 15 are placed on the plane of four columns.Accurate levelling gear 5,6,7,8 at vertical direction employing and column 2,3,4 identical spiral micro-measuring structures carry out precision adjustment, and horizontal direction adopts the principle of " screw rod rotates, and nut moves " to realize accurate the adjustment, precision can reach 0.01mm, the spiral micro-measuring structure promptly is same as existing micrometer caliper, belongs to the fields of measurement known technology, so this structure does not repeat them here.
In conjunction with Fig. 2 and shown in Figure 3, accurate levelling gear comprises vertical direction adjusting mechanism, horizontal direction adjusting mechanism and is fixed mechanism; The vertical direction adjusting mechanism is positioned at the bottom of accurate levelling gear, and its bottom cooperates with the T type groove of guide rail, regulates part and adopts the spiral micro-measuring structure; Montant 26 is connected the horizontal direction adjusting mechanism of accurate levelling gear with the vertical direction adjustment member of lower end.The horizontal direction adjusting mechanism is positioned at the middle part of accurate levelling gear, mainly comprise following planker 16, screw rod 24, go up planker 17, nut 27 and dragging article 18, adopt being slidingly connected of oat tail groove structure between last planker 17 and the following planker 16, guaranteed the stability when last planker moves; Montant 26 is fixed on down screw rod 24 in the planker 16 with screw mandrel retainer plate 25, nut 27 is fixed together with last planker 17 riveteds, when nut 27 moves, last planker 17 also moves in the horizontal direction, screw rod 24 cooperates with nut 27, screw rod 24 can only rotate in following planker 16 and can not move, during rotating screw bolt 24, driving upward by nut 27 transmissions, planker 17 moves horizontally, the upper surface of last planker 17 is provided with the holder bar 18 of placing framework border, adopt being slidingly matched of oat tail groove structure between holder bar 18 and the last planker 17, guaranteed the synchronism that moves with last planker, can have more part to place at grade to guarantee the backlight framework border according to border width and the different processing different in width of length and the holder bars of length of backlight framework, improve locating accuracy, reduced the complicacy of adjusting the location.Be fixed mechanism and be positioned at the top of accurate levelling gear, mainly comprise screw rod 21, chute 22, montant 23 and hold- down nut 19,20, screw rod 21 vertically passes chute 22, screw rod 21 can be in chute horizontal direction and vertical direction move, screw rod 21 is fixed by the hold-down nut 19 and 20 that is positioned at chute 22 top and bottom, and chute 22 is fixedlyed connected with the last planker 17 of horizontal direction adjusting mechanism by montant 23.In the process of adjusting, in order to make moving of backlight framework and moving synchronously of tool, compress by compressing montant 23 and the last planker hold-down mechanism that is fixed together, clamping screw 21 can move for 22 li compressing chute according to the height of compacted workpiece and width, after moving on to correct position, can utilize to compress lower nut 19 and compress top nut 20 to be fixed.Like this, when planker drive workpiece moved on rotating screw bolt makes, hold-down mechanism also was to move together.
Use the utility model to position when adjusting, at first, at the size of backlight framework to be positioned four columns are moved to suitable position on guide rail, and the spiral micro-measuring structure is adjusted to zero-bit, to guarantee the height unanimity of four columns.Four corner angle of backlight framework are placed on four planes of column.
Secondly, determine the quantity of accurate levelling gear and the holder bar of different in width and length as required.Generally, smaller every limit of backlight framework only needs an accurate levelling gear to get final product, and selected holder bar length and width also can be smaller.For bigger backlight framework, if frame is wide and thick, distortion is not very big, and every frame needs an accurate levelling gear just can reach requirement, but to according to circumstances select long and wide holder bar for use, so just can make more local the placement at grade on the frame.And if bigger backlight frame is thinner, soft yielding, just need increase the quantity of accurate levelling gear and the length of holder bar according to circumstances, so just can reach good location and adjust effect.
After choosing accurate levelling gear and holder bar, accurate levelling gear is inserted in the T type groove of guide rail or slide rail, the frame of backlight framework is placed on the holder bar, and the according to circumstances suitable position of accurate levelling gear and holder bar of adjusting is to reach best positioning states.After placement is finished, accurate levelling gear is transferred to zero-bit, with guarantee with four columns at sustained height.
After coarse adjustment is finished, utilize pressing section above the accurate levelling gear with the backlight frame fixation.At this moment, just fine tuning as required.Because vertical direction upper pillar stand and accurate levelling gear can reach requirement all in zero-bit so only need finely tune.Horizontal direction can be utilized finely tuning of accurate levelling gear.To be adjusted behind basic standard, can utilize the three coordinate measuring machine touch trigger probe further to measure the degree of accuracy of adjusting the location to estimate.So repeatedly several times, get final product up to reaching needed standard state.
After finish accurate adjustment location, just can utilize the three coordinate measuring machine laser scanning testing head to carry out reverse reconstruct and full-scale the detection.Simultaneously, navigating under the situation of standard state, the fine structure size of backlight framework can be used the minor diameter gauge head precision measurement of three coordinate measuring machine.
