The specific embodiment
below in conjunction with accompanying drawing, the utility model is further described:as shown in Figure 1, large scale rectangle weldment alignment system end positioning clamping device, is comprised of two ends positioning clamping device 1,4 and transformation mechanism 3; 2 is large scale weldment, is placed between left end positioning clamping device 1 and right-hand member positioning clamping device 4, and horizontal cross moves the weldment of transformation mechanism 3 for alignment different length.
As Fig. 2,, as shown in 3,4,5: wherein positioning clamping device is by fixed head 5, base plate 6, round guide 7, locating piece 11, fixed block 14,, clamp 15, positioning cylinder 17, clamping cylinder 18 and support wheel 19 form, it is characterized in that: a left side, right two ends positioning clamping device structure is identical, transformation mechanism 3 is arranged on the bottom of right-hand member positioning clamping device 4, the T shape fixed head 5 of positioning clamping device is fixedly connected with base plate 6, round guide 7 two ends are fixed on round guide fixed head 8, round guide fixed head 8 is fixed on base plate 6, adjusting locating piece 9 is fixed on fixed head 5, locating rack 10 is fixed on base plate 6, between two adjustment locating pieces 9, in the middle of locating rack 10 and two adjustment locating pieces 9, leave gap, locating rack 10 is arranged vertically with round guide 7, the top of locating rack 10 has clamped locating piece 11, locating piece afterbody contacts with positioning cylinder expansion link, positioning cylinder 17 is fixed on (for longitudinal register) bearing base plate 12 on locating rack 10 and is slidably connected at round guide 7, on bearing base plate 12, be provided with two fixed mounts that are arranged symmetrically with 13, a fixed mount 13 is provided with gathering sill 16, gathering sill 16 bottoms are right angle, top is obtuse angle, on bearing base plate 12, establish support wheel 19, support wheel 19 is positioned at the side of two fixed mounts, and be arranged vertically with two fixed mounts 13, clamping cylinder 18 is connected on the fixed mount 13 of opposite side.(for horizontal clamping)
During work, first, positioning cylinder 17 resets with clamping cylinder 18, according to the length of weldment, moves transformation mechanism, and weldment is put on the support wheel 19 of clamping device along gathering sill 16.Secondly, by the screw of adjusting on locating piece 9, can finely tune locating rack 10, control positioning cylinder 17 locating piece 11 is snapped in locating slot, clamping cylinder 18 clamps the weldment between clamp 15 and fixed block 14, completes longitudinal register and the clamping of weldment.Finally, when weldment crooked position is carried out to alignment, for guaranteeing that alignment deformation force does not have influence on all the other positions, locating piece 11 resets, and weldment two ends can be along guide rail longitudinal sliding motion to guarantee smooth alignment.
As shown in Figure 6: transformation mechanism is comprised of base 20, line rail plate 21, two line rails 23, hand latches 24; The base 20 upper fixed line rail plates 21 of transformation mechanism, fix wired rail 23 on line rail plate 21, slidably connect the frame 22 of remodeling on line rail 23, on the frame 22 of remodeling, are connected with fixed head 5.Two ends, left and right positioning clamping device structure is identical, and the positioning cylinder 17 on the positioning clamping device at two ends and clamping cylinder 18 have been controlled the positioning and clamping of weldment by PLC, limit switch and pressure sensor are housed on it.Clamping device can do vertical equity along round guide 7 and move.Transformation mechanism is arranged on the bottom of right-hand member positioning clamping device 4 to control its horizontal cross motion.
When weldment located lateral, positioning cylinder 17 and clamping cylinder 18 reset, and now locating piece 11 departs from locating slot, and large scale weldment 2 is placed in gathering sill 16 by crane, for preventing that large scale weldment 2 from touching other checkout gears; Control the left positioning clamping device 1 at two ends and right positioning clamping device 4 and along round guide 7, do that vertical equity moves and mobile transformation mechanism 3 transverse horizontal are moved, make weldment just in time be placed on the top of two support wheels 19 in left and right, make left end withstand on the stiff end of gathering sill 16, fine setting transformation mechanism 3 makes gathering sill 16 one end of right-hand member withstand on the right-hand member of weldment, regulating hand latch to make transformation mechanism 3 stop holding position fixing, has so just completed the located lateral of weldment.
When the longitudinal register of weldment is when clamping, the longitudinal register of weldment and the detection clamping for its linearity, need to make measured surface parallel with laser displacement sensor.By the screw of adjusting on locating piece 9, can finely tune locating rack 10, to guarantee the degree of accuracy of locating piece location.Positioning cylinder 17 work make locating piece 11 do transverse movement, by the signal of pressure sensor on it, judge, locating piece 11 is withstood in locating slot, and the left positioning clamping device 1 at two ends and right positioning clamping device 4 cannot do lengthwise movement along round guide 7 like this.Positioning cylinder 17 work make clamp 15 carry out lengthwise movement, by pressure sensor on it, judge that whether the weldment between fixed block 14 and clamp 15 is clamped, now completed the clamping of weldment, side is vertical with laser displacement sensor, laser displacement sensor can do horizontal cross along the datum line rail on fixed frame and move, and by calculating with the distance on weldment surface, carries out the detection of its linearity.
When alignment system is carried out alignment to weldment crooked position, fixing if weldment two ends still keep, the distortion allowance of middle part will cause all the other positions that secondary deformation occurs, and make like this alignment complicated.Positioning cylinder 17 and clamping cylinder 18 reset again, can allow the two ends of weldment do lengthwise movement along round guide 7 during the alignment of bent intermediate position like this, and all the other positions of weldment can not make two ends that secondary deformation occur because of the distortion allowance of middle part.
