The high-precision manufacturing process comprises the following steps that S100, a latticed shell space structure three-dimensional model is established, latticed shell rod pieces and partition unit mesh construction drawing design is deepened, and finally the size of latticed shell steel beams and coordinates of control points are exported and machined; s200, a reticulated shell machining jig frame is designed, unit installation areas are divided, multiple rounds of deepening design are carried out to obtain an optimal scheme, and a construction method and a technological process are determined; s300, the height of the adjustable jig frame is adjusted, and then welding is conducted; s400, the installed local reticulated shell structure is cooperatively hoisted through a double-machine-table crane; s500, measurement and precision control are carried out; s600, welding forming is carried out; and S700, the glass curtain wall is installed. The height adjustable device is arranged above the combined stand column, the adaptability of equipment is effectively improved, the technical problem that in a traditional method, when the supporting height is not enough, the whole stand column needs to be temporarily replaced is solved, continuous adjustment of the supporting height is achieved through lead screw transmission, and the adjustment range is more comprehensive.

    本发明公开了一种异形复杂曲面网片高精度制造工艺及其使用装置,包括如下步骤:S100:建立网壳空间结构三维模型,深化网壳杆件和分区单元网片施工图设计,最后导出网壳钢梁尺寸及控制点坐标并加工;S200:设计网壳加工胎架,划分单元安装区域,并进行多轮深化设计得出优选方案,确定施工方法和工艺流程;S300:对可调节胎架的高度进行调整后进行焊接;S400:采用双机台吊对安装好的局部网壳结构协同吊装;S500:测量及精度控制;S600:焊接成型;S700:安装玻璃幕墙。通过在组合立柱上方设置高度可调装置,有效的提高了设备的适应性,解决了传统方法中当支撑高度不够时需要临时更换整个立柱的技术问题,且通过丝杆传动实现支撑高度的连续调节,调节范围更全面。
