新型接管装焊定位夹具的设计开发

Design of a New Fixture for Welding and Positioning of Pipe Joint

为了保证产品筒体上焊接竖直接管和水平短管相对位置要求,结合产品结构尺寸设计了专用接管装焊定位夹具工装,并应用强调理论对定位夹具主要受力件的强度进行了校核,确保使用过程不产生塑性变形影响定位精度,经过实际使用检验表明该夹具结构合理,起到了准确定位接管相对位置的作用。

In order to ensure the relative position of welded vertical pipe and horizontal short pipe on the product cylinder body,special fixture for welding and positioning fixture is designed in combination with the size of product in this paper.The strength of the main stressed parts in the positioning fixture is checked with the emphasis theory to ensure that there isn't any plastic deformation affecting the positioning accuracy during the using process.The practical test shows that the fixture has reasonable structure,and it has the function of accurately positioning the relative position of the nozzle.
