The invention relates to an alignment and spacing method for steel crane beam rail pressing plate bolt row hole positions. The method comprises the following steps of step 1: measuring manufacturing deviation; step 2: establishing a solid model; step 3: simulating assembly checking; step 4: centering a web plate of a crane beam, and aligning the center of an upper flange plate of the crane beam; step 5: positioning bolt hole positions; step 6: performing lofting and alignment positioning; step 7: checking and accepting the hole positions; step 8: repeating the steps 6 and 7 until all lofting work is completed; and step 9: performing a batch drilling process after the lofting is finished. The positioning work of the bolt row hole positions can be quickly and conveniently completed, the accuracy and reliability of drilling alignment positioning are increased, the working content of process review and acceptance is simplified, the manufacturing progress is accelerated, and the manufacturing cost is effectively reduced.
本发明涉及一种钢吊车梁轨道压板螺栓排孔位置的定线定距方法,包括如下步骤:步骤一:测量制作偏差:步骤二:建立实体模型:步骤三:模拟装配校核:步骤四:对吊车梁的腹板分中、上翼缘板中心定线;步骤五:对螺栓孔位置定位;步骤六:放样定线定位;步骤七:孔位校验验收;步骤八:重复步骤六、七,直至完成全部放样工作;步骤九:放样完成后,即可转入批量钻孔工序。本发明可快速便捷的完成螺栓排孔位置的定位工作,既增加了钻孔定线定位的精度可靠性,又简化了工序复查验收的工作内容,加快了制造进度并有效降低了制造成本。
