The invention discloses a mounting method of instrument board cross beam mounting plates and the instrument board cross beam mounting plates. The mounting method comprises the following steps that: S1, the instrument board cross beam mounting plates are manufactured; S2, main welding of a vehicle front cabin assembly is completed; and S3, with the vehicle front cabin assembly as the benchmark, theinstrument board cross beam mounting plates are positioned and welded to the vehicle front cabin assembly. According to the mounting method of the instrument board cross beam mounting plates, after main welding of the vehicle front cabin assembly is completed, the instrument board cross beam mounting plates are welded and mounted on the vehicle front cabin assembly, and through backward performing of the welding step of the instrument board cross beam mounting plates, the welding tolerance accumulation of the instrument board cross beam mounting plates in the welding process of the vehicle front cabin assembly is reduced as much as possible, the position precision of the left instrument board cross beam mounting plate and the right instrument board cross beam mounting plate is effectivelyimproved, then the mounting precision of the instrument board cross beam is improved in the subsequent process, and the accuracy of the relative position of the instrument board cross beam and the vehicle front cabin assembly is guaranteed.
本发明公开了一种仪表板横梁安装板的安装方法及仪表板横梁安装板,其包括如下步骤:S1、制造仪表板横梁安装板;S2、完成车辆前舱总成的主要焊接;S3、以车辆前舱总成为基准,将仪表板横梁安装板定位并焊接于车辆前舱总成。在仪表板横梁安装板的安装方法中,在完成车辆前舱总成的主要焊接之后,再将仪表板横梁安装板焊接安装到车辆前舱总成上,以通过对仪表板横梁安装板的焊接步骤的后移,尽可能地减少仪表板横梁安装板在车辆前舱总成焊接过程中产生的焊接公差累计,有效提高左右两块仪表板横梁安装板的位置精度,进而在后续工序中,提高仪表板横梁的安装精度,保证仪表板横梁与车辆前舱总成相对位置的准确。
