Digital high-precision rapid splicing method for welded ball net rack
The invention discloses a digitalized high-precision rapid splicing method for a welded ball net rack. The digitalized high-precision rapid splicing method specifically comprises the following steps that (1) on the basis of an original net rack deepening graph, the arc length between intersecting center points of a web member, an upper chord member and an upper chord ball is provided; (2) according to the arc length, determining rod piece center point positions of an upper chord rod piece and a web rod on the surface of the welding ball; (3) drawing a rod piece intersecting line on the surface of the welding ball by taking the central point of the rod piece as a circle center according to the section specifications of the web member and the chord member; and (4) the rod pieces and the welding balls are locally fixed, and the assembled basic units are formed. According to the uniqueness of the spatial geometric position relationship between the welding ball and the connected rod piece, the relative position relationship between the rod and the ball is accurately calculated by utilizing the spatial geometric principle, the relative position relationship between the rod and the ball can be rapidly positioned by matching with a set of complete operation process, and a high-precision rapid assembly method is provided for field assembly of the welding ball net rack.
本发明公开了一种焊接球网架数字化高精度快速拼装方法，具体包括如下步骤：1）在原有网架深化图的基础上提供腹杆、上弦杆与上弦球相贯中心点相互间弧长长度；（2）根据弧长，在焊接球表面确定上弦杆件及腹杆的杆件中心点位置；（3）根据腹杆及弦杆的截面规格，以杆件中心点为圆心，在焊接球表面画出杆件相贯线；（4）将杆件与焊接球局部固定，形成拼装基本单元。本发明依据焊接球与相连杆件的空间几何位置关系的唯一性，利用空间几何原理精确计算出杆球相对位置关系，并配合一套完整的操作流程能够快速定位出球杆相对位置关系，为焊接球网架现场拼装提供了一种高精度快速拼装方法。
