Flexible welding fixture of end plate of wagon balance

The utility model discloses a flexible welding fixture of an end plate of a wagon balance. The flexible welding fixture of the end plate of the wagon balance is mainly used for achieving the positioning of the central line of the end plate of the wagon balance and the clamping of the end face of the end plate of the wagon balance. The flexible welding fixture of the end plate of the wagon balance comprises a support, a mechanism moving in the X direction, a mechanism moving in the Y direction, an end face clamping mechanism, a side face positioning and adjusting mechanism, limiting plates and a reshaping block, wherein the mechanism moving in the X direction is used for meeting the requirements of variation of the wagon balance in the length direction, the mechanism moving in the Y direction is used for achieving the adjustment of the end plate of the wagon balance in the width direction, the end face clamping mechanism is used for achieving the movement of the end plate of the wagon balance in the X direction and is also used for clamping and reshaping the end plate of the wagon balance, the side face positioning and adjusting mechanism is used for enabling the central line of the end plate to be aligned with the central line of a U-shaped beam, the four limiting blocks can achieve the positioning of the wagon balance in the Y direction, and the reshaping block is used for the distortion straightening of the U-shaped beam in the vertical direction after the U-shaped beam is fully welded. The flexible welding fixture of the end plate of the wagon balance has the advantages of being simple in structure, reliable, high in automation degree, and capable of solving the problem of inaccurate positioning in the wagon balance manufacturing process at present.
