The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the utility model is equipped with respectively successively in transmission roller channel 10 both sides and transmission roller channel 10 parallel linear guides 5 and tooth bar 4, three slide blocks 8 respectively are housed on two line slideways 5, end on each slide block 8 all is equipped with stepper motor 6, stepper motor 6 is by gear 3 and tooth bar 4 engagements, the other end of slide block 8 is equipped with aligning 7, respectively there is a limited block 2 at the two ends of two toothed rack 4, line slideway 5 one end and three laser sensors 1 are housed therein in transmission channel 10 1 sides, laser sensor 1 is on same straight line, spacing equates, and be parallel to transmission channel 10, three laser sensors 1 and stepper motor 6 all are connected with computer 11, and computer 11 is determined each aligning 7 moves and feeding by the image data of analyzing three laser sensors 1; Computer 11 makes slide block 8 drive aligning 7 by control step motor 6 and is moving along line slideway 5 directions.
As shown in Figure 2, described aligning 7 is the piston rod of hydraulic cylinder, the oil circuit of its hydraulic cylinder is: the hydraulic pump oil-in connects fuel tank by oil filter, a road of hydraulic pump oil-out links to each other with 3-position 4-way servo valve oil-in through first check valve, the oil return opening of 3-position 4-way servo valve meta links to each other with fuel tank, first oil-out of 3-position 4-way servo valve directly links to each other with the rodless cavity of hydraulic cylinder, and second oil-out of 3-position 4-way servo valve links to each other with the rod chamber of hydraulic cylinder with the protective device of second check valve parallel connection through first overflow valve; Second overflow valve in another road of hydraulic pump oil-out links to each other with fuel tank, and links to each other with Pressure gauge through switch.
Operation principle of the present utility model is as follows:
Three laser sensors 1 adopt line-of-sight course to be carried out displacement measurement to rectifying workpiece 9, require transmission roller channel 10 each spacing feedings by three laser sensors 1; The data that 11 pairs of three laser sensors 1 of computer are gathered are carried out match by least square method, then a differentiate are carried out in the gained matched curve, obtain its extreme point, carry out the secondary differentiate again and obtain its flex point.
Whole aligning process can be divided into the measurement and the aligning in the later stage two big steps in early stage.At first, rectified workpiece 9 under the conveying of transmission roller channel 10 earlier successively through three laser sensors 1 of front, here transmission roller channel 10 is according to the spacing feeding of three laser sensors 1, so that laser sensor 1 can adopt line-of-sight course calculated line degree when gathering displacement, with the straightness error of cancellation element self introducing.After treating to be entered aligning district's certain-length by strong workpiece 9, transmission roller channel 10 feed-disablings, computer 11 is by adopting least square method to carry out match to measured data, draw the contour curve of being rectified workpiece 9, control step motor 6 makes aligning 7 go to the relevant position then, and the position grouping of aligning 7 is with being illustrated for example here.
Be illustrated in figure 3 as the aligning 7 positions relation when being rectified workpiece 9 for single radian.In this case, only need use three alignings 7, wherein two is as supporting a function that really plays the aligning head.An aligning 7-4 and an aligning 7-6 for being rectified the two ends that workpiece 9 enters aligning district part, are fed into position of center line place along vertical transfer roller-way 10 directions along transmission roller channel 10 direction correspondence positions, the support during as aligning.An aligning 7-2 is entered the limit of aligning district's part along transmission roller channel 10 direction correspondence positions for rectifying workpiece 9, just align a 7-2 and is determined according to elastic-plastic mechanics theory by the length travel amount of extreme point along the vertical transfer roller-way 10 direction amount of feeding at displacement absolute value maximum point place.
