[0002] The forklift fork carriage is a core load-bearing component of a forklift, and its assembly quality directly affects the stability and safety of the forklift. Traditional fork carriage assembly mainly relies on manual positioning and welding, which presents the following problems: 1. Low positioning accuracy: Manual marking and template positioning are prone to cumulative errors, which can lead to misalignment of assembly holes and affect the compatibility of fork installation. 2. Low efficiency: The clamping needs to be adjusted multiple times, and the workpiece needs to be flipped over for reverse operation after welding, which is time-consuming and labor-intensive. 3. Poor consistency: It is difficult to ensure the controllability of welding deformation in mass production, resulting in a high rework rate.
