The present embodiment also discloses a kind of assembly welding method that carries out assembly welding according to rotation assembly welding frock as above that uses, the difference of the assembly welding method in itself and embodiment 1 is: the each parts of described gear-box upper box carry out in the step of preliminary welding, gear-box upper box coaming plate being enclosed in the process of spot-welded or the each parts of described gear-box lower box carry out in the step of preliminary welding, gear-box lower box coaming plate being enclosed in the process of spot-welded, all the positions according to spot-welded point, by moving U-shaped slide block 1 and U-shaped slide block two and rotating U-shaped compressor arm 472, make coaming plate clamping screw 473 be pressed on the compression point of gear-box upper box coaming plate 6 or make compression point that coaming plate clamping screw 473 is pressed on gear-box lower box coaming plate 6 along with spot-welded point moves gradually, until complete, gear-box upper box coaming plate 6 encloses spot-welded process or gear-box lower box coaming plate 6 encloses spot-welded process.

When coaming plate being enclosed between biside plate in prior art, be directly to press coaming plate with hand, knock gently coaming plate with hammer, make coaming plate between biside plate when suitable position, then by spot-welded post between it. but, operate and waste time and energy like this, have a strong impact on operating efficiency. and in the present embodiment, carry out instead of manual hammering assembling coaming plate by coaming plate compressing member assembling coaming plate and complete spot-welded, in the time carrying out the preliminary spot-welded of gear-box upper box, first, first the U-shaped open card of described U-shaped slide block 1 and U-shaped slide block two be combined on the sidepiece of described swivel plate 161 and make the yoke limit 48 of described U-shaped slide block 1 and U-shaped slide block two all be positioned at top position, move described U-shaped slide block 1 and U-shaped slide block two behind suitable position along the sidepiece of described swivel plate 161 again, U-shaped slide block 1 and U-shaped slide block two are fixed on position suitable on swivel plate 161, at this, can on the sidepiece of swivel plate 161, positive stop be set, U-shaped slide block one and U-shaped slide block two are contacted with positive stop, thereby U-shaped slide block one and U-shaped slide block two are fixed, also can fastening bolt be set at U-shaped slide block one and U-shaped slide block two, thereby pass U-shaped slide block one and swivel plate and pass U-shaped slide block two and swivel plate is fixed on U-shaped slide block one and U-shaped slide block two on position suitable on swivel plate by fastening bolt by fastening bolt, and then by the dual-side of the U-shaped compressor arm 472 with coaming plate clamping screw by bearing pin 49 respectively with a side of described U-shaped slide block 1 and U-shaped slide block two on yoke limit 48 be hinged together, again gear-box upper box coaming plate 6 is enclosed in toward its other one end between the biside plate 5 of described gear-box upper box from biside plate one end of described gear-box upper box successively gradually along the die body surrounding edge portion 18 of described top box die body, and in the process enclosing, by U-shaped compressor arm, 472 coaming plate clamping screws 473 are turned to the surrounding edge top position of a pad that carries out spot-welded, after rotateing in place, turn coaming plate clamping screw 473, one end of coaming plate clamping screw 473 is pressed on the coaming plate 6 of this pad, thereby coaming plate 6 is pressed in the die body surrounding edge portion 18 of top box die body, carry out again spot-welded, after the coaming plate spot-welded from coaming plate clamping screw vicinity, the coaming plate clamping screw 473 of back-outing again, by U-shaped compressor arm 472, coaming plate clamping screw 473 is turned to along the surrounding edge top position of the next spot-welded of coaming plate length direction, and then turn coaming plate clamping screw 473, one end of coaming plate clamping screw 473 is pressed on the coaming plate 6 of this pad, coaming plate 6 is carried out to spot-welded, until complete the spot-welded process of whole gear-box upper box coaming plate.

In the time that lower box coaming plate is carried out to spot-welded, with above-mentioned upper box coaming plate is carried out to spot-welded step is the same, all utilize coaming plate compressing member to complete. The problem of so just having avoided hand bumping assembling coaming plate and cause operator's labour intensity to increase, operates time saving and energy saving like this, has improved greatly operating efficiency. In addition, in prior art, utilize the mode of hammer hammering also can cause hammering vibration, gear-box fitted position is had to impact, utilize coaming plate compressing member to avoid this point.

In addition, described rotation assembly welding frock can also comprise U-shaped side plate clamping element 50, the fishbolt 503 that described U-shaped side plate clamping element 50 comprises U-shaped clamp 501, is welded on the binding nut 502 on described U-shaped clamp 501 one end and matches with described binding nut 502.

In the time that certain part on coaming plate is carried out to spot-welded, U-shaped side plate clamping element 50 is clamped on both sides side plate 5, fishbolt 503 contacts with a side side plate 5, the other one end of U-shaped clamp 501 contacts with an other side side plate 5, by tightening fishbolt 503, U-shaped side plate clamping element 50 is clamped on both sides side plate 5. Like this, further ensure the fitted position between both sides side plate 5 and coaming plate 6.

In sum, rotation assembly welding frock in the present invention can play an effect that rigidly fixes support to each parts of upper and lower casing, reduce the torsional deformation of gear-box, the torsional deformation of each gear-box parts Produced after Welding is controlled to pattern requires and following process margin range in, do not need to carry out soldering, improve welding quality, reduced workman's labour intensity, improved production efficiency; Utilize backing plate male part position, location weld location and utilize eckband locating convex block to position welding to gear-box eckband gear-box connecting plate, both each parts on assembling gear case fast, can ensure again the fitted position between each parts, assembly welding is got up more convenient, in addition, utilize the present invention to carry out gear-box after assembly welding while carrying out the demoulding, simple and convenient, the demoulding is easy, be convenient to workman's operation, reduce the operating time of whole assembly welding, further reduced workman's working strength, improved operating efficiency; Assembly welding method in the present invention is to adopt rigid fixation to carry out welding to gear-box, can reduce the torsional deformation of gear-box, improves welding quality; Utilize coaming plate compressing member assembling coaming plate to carry out instead of manual hammering assembling coaming plate and complete spot-welded, the problem of having avoided hand bumping assembling coaming plate and cause operator's labour intensity to increase, operate time saving and energy saving, improve greatly operating efficiency, also avoid in addition hammering vibrations to be out of shape influential problem to gear-box fitted position and occurred, further improved welding quality.

Above embodiment is used for illustrative purposes only; but not limitation of the present invention; person skilled in the relevant technique without departing from the spirit and scope of the present invention; can also make a variety of changes or convert; therefore all technical schemes that are equal to also should belong to protection scope of the present invention, and protection scope of the present invention should be limited by each claim.
