我厂用杠杆原理调修货车焊接结构(主要C_(50)C_6、C_1等车型)车体倾斜的方法,经过一年摸索取得了一定的效果.现将其操作工艺介绍,以供兄弟单位参考. 引起货车车体倾斜的主要原因不外乎:(一)原设计车体结构刚度弱,经过长期运用后产生永久变形;(二)在制造时没有严格的按工艺要求进行生产,尤其是心盘安装处中梁两侧未在同一水平面上,这种情况在焊结构底架中尤为常见.在货车检修时一般只局部解体,为了解决车体倾斜问题只有在心盘座处(即中梁隔板)进行调烤校正.C_(50)、C_6、C_1型货车焊接中梁因其上心盘座采用钢板焊接,其刚度较铸钢者差,因
I plant with lever principle repair truck welding structure (the main C_ (50) C_6, C_1 and other models) body tilt method, after a year of groping and achieved some results. Now the operation of its process for reference Brothers units The main reason causing the truck body to tilt is nothing more than: (1) the rigidity of the original design body structure is weak and permanent deformation occurs after long-term application; (2) there is no strict production according to the process requirements during manufacturing, especially the heart Plate installation at both sides of the beam is not on the same level, this situation is particularly common in the welded chassis.In the truck maintenance is generally only partially disintegration, in order to solve the problem of body tilt only at the heart plate seat (ie, the beam Plate) to adjust the grilling correction.C_ (50), C_6, C_1 type of truck welding beam because of its center plate seat plate welding, the stiffness of the cast steel who are poor, due to
