Abstract

The invention relates to the technical field of rail passenger car manufacturing equipment, in particular to a roof flexible welding fixture system. It solves the technical problem that the adjustment of the fixture system is complicated and the effective production time is wasted when the stainless steel vehicle roof welding manufacturing process in the prior art is manufactured and changed. Specifically, it includes a control unit that receives the roof model information of the rail passenger vehicle based on a hardware device, and the hardware device classifies the roof model information into multiple execution signals based on the firmware loaded on the hardware device; the preset movement distance or preset movement distance formed by the execution unit It is assumed that the movement height is based on the instruction of the execution signal to drive the corresponding execution unit to move; the execution unit feeds back the coordinates of its own X-axis, Y-axis, and Z-axis to the control unit, which is received by the hardware device. The technical solution of the present application can effectively improve and optimize the production of stainless steel roof welding, can greatly shorten the tooling changeover time, and release the production capacity of the stainless steel production line.

Description

technical field

[0001] The invention relates to the technical field of rail passenger car manufacturing equipment, in particular to a roof flexible welding fixture system. Background technique

[0002] In the prior art, in the manufacturing process of stainless steel roof welding of rail passenger cars, there are the following problems with the use of traditional fixtures. For example, the roof assembly welding fixture still uses a manual tape measure to measure the size and adjust manually. This process is biased towards manual skills and is not easy to control. , and the adjustment time is long. The adjustment time of different fixtures for the same item to be manufactured is estimated to be about 1-2 working days. If the fixture cycle of different items to be manufactured is involved, the adjustment period will increase by 2-3 working days, resulting in a waste of production capacity during the model change; in addition, The positioning accuracy is poor, manual adjustment...
