Detailed description of the invention
Be illustrated in figure 1 the structural representation of frock, comprise base plate 1, base plate 1 is provided with interior side positioning mechanism and outer side positioning mechanism, described interior side positioning mechanism is: the first fixed head 2 being provided with multiple vertical setting in the middle part of base plate 1, " 7 " body 3 that You Transverse puts on the sidewall of each the first fixed head 2, the position that the traversing section of " 7 " body 3 that Suo Shu Transverse puts is connected with vertical section by the first rotating shaft and the first fixed head 2 hinged, the vertical section of " 7 " body 3 that Suo Shu Transverse puts is positioned near base plate 1 edges of boards side, described vertical section is positioned at the upside of traversing section, the inner end of described traversing section by the second rotating shaft and montant 4 hinged, the bottom of described montant 4 is connected with cross bar 5, the bottom of described cross bar 5 is connected with the piston rod of cylinder 6, the bottom of described montant 4 is also connected with spring 7, described outer side positioning mechanism is: be furnished with multiple second fixed head 8 at the edge of base plate 1 along the bearing of trend of base plate 1 edges of boards, the second fixed head 8 is provided with active grab.Base plate 1 is also provided with the through hole 10 matched with the perforate on the fuel tank sidewall 11 of transformer, and is provided with latch, base plate 1 is also provided with the locating piece 14 for locating oil tank of transformer corrugated plating 12.
Certain distance is left between interior side positioning mechanism and outer side positioning mechanism, here the distance left needs the steel plate of welding to arrange to place, oil tank of transformer is welded by four sides steel plate and cover plate, relative two sides steel plate is wherein had to be provided with corrugated plating 12, first fixed head 2 is two rows, often arrange four, and be evenly arranged, it is positioned at the medium position of base plate 1, second fixed head 8 is positioned at the marginal position of base plate 1, each edges of boards place is provided with two, the first block plate i.e. fuel tank sidewall 11 that need welding are placed between two detent mechanisms, plug latch fuel tank sidewall 11 and base plate 1 are fixed, then corresponding cylinder 6 is braked, its piston rod upwards pushes up, then " 7 " body 3 is around the first axis of rotation, the downward lateral movement of vertical section, withstand from inner side by fuel tank sidewall 11, then the active grab on outer side positioning mechanism second fixed head 8 is utilized to withstand fuel tank sidewall 11 from outside, after fixing, the sidewall with corrugated plating 12 is fixed between the two equally, due to corrugated plating 12, so be provided with the locating piece 14 for locating on base plate 1, shape and the corrugated plating 12 of locating piece 14 are suitable, namely be just in time stuck in when corrugated plating 12 puts down on locating piece 14, then inside and outside side positioning mechanism is in like manner utilized to be clamped, operate so successively, weld together after four side plates of composition oil tank of transformer are all located, finally weld on the base plate cover of cover plate i.e. oil tank of transformer.Be illustrated in figure 2 the structural representation of oil tank of transformer in frock during positioning welding.
In addition, the limited block 9 be connected with the first fixed head 2 is provided with in the upside of traversing section, on each first fixed head 2, " 7 " quantity of body 3 is two, and vertically arrange up and down on the sidewall of the first fixed head 2, first fixed head 2 is evenly fixed on base plate 1 in two rows, be provided with the cushion block 13 for support oil tank of transformer at the top of first fixed head 2 at four end angle places, described active grab comprises horizontal active grab 15 and plug-type active grab 16.It is constant that the setting of limited block 9 and locating piece 14 determines the fixed position of steel plate in frock, when relocating the steel plate of the fuel tank of lower a set of needs welding after the good a set of fuel tank of welding, the position of the latter's steel plate and the position of the former steel plate are identical, because had limited block 9 so the degree of cylinder 6 piston rod upwards ejection is identical, so the angle of the downward sideway swivel of vertical section is also identical, namely vertical section is the same from inner side to the ejection dynamics of steel plate, and the clamping degree of the active grab of outer side positioning mechanism can regulate, when vertical section is rotated in place time, only clamp is adjusted to the outside of withstanding steel plate, also because there has been the setting of locating piece 14, the position of locating piece 14 on base plate 1 is constant, so corrugated plating 12 position be stuck on locating piece 14 is also constant, and the vertical section ejection dynamics of interior side positioning mechanism is constant, so be also constant with the sidewall locations of corrugated plating 12, for the outer side positioning mechanism of fixed oil tank sidewall 11 only with plug-type active grab 16, it need to a direction ejection fuel tank sidewall 11, but for the side box wall with corrugated plating 12, the existing plug-type active grab 16 of outer side positioning mechanism corresponding to it, have again horizontal active grab 15, it can clamp from orthogonal both direction corrugated plating 12.So identical by this tool locating transformer oil tank structure out, accurate positioning, ensure that the uniformity of producing product, improves working (machining) efficiency, ensure that quality.
In sum: this frock is divided into interior side positioning mechanism and outer side positioning mechanism, can be fixed the steel plate be clipped in wherein from inside and outside both sides simultaneously, welding front spring separates, between inside and outside two the detent mechanisms in turn steel plate of all directions being clipped in homonymy respectively, namely be clipped in " 7 " between body and active grab, and itself and through hole are fixed by latch by the perforate of fuel tank sidewall bottom, first corrugated plating can be found accurately placement location by locating piece for the sidewall with corrugated plating, then its top is clamped by inside and outside side positioning mechanism again, for with corrugated plating side steel plate, its outer side positioning mechanism not only comprises horizontal active grab but also comprise plug-type active grab, clamping position can be carried out from the both direction of corrugated plating, and the vertical section of " 7 " body can move downward thus the inner side of withstanding steel plate is fixed under the promotion of the related montant of cylinder in interior side positioning mechanism, and with limited block on the upside of traversing section, cylinder ejection can be prevented excessive, and regracting cylinder piston rod after welding well, under the pulling of spring, vertical section gets back to original position again, leave inside steel plate, the welding of cover plate i.e. oil tank bottom plate is carried out again after the Plate Welding of four direction, this frock can position from inside and outside both direction steel plate, accurate positioning is firm, accelerate speed of welding, ensure that product quality.
