Technical Problem

[0004]现有切割工装存在明显的局限性与缺陷：其一，适配性差，专用工装的仿形支撑结构与切割轨迹均针对单一车型设计，当面对不同造型、尺寸的油箱外壳时，需更换整套工装或进行大规模调试，导致生产通用性不足，增加了设备投入与换型时间成本；其二，切割精度难以保证，传统机械导轨导向方式易受振动、磨损影响，且人工定位工件的方式存在误差累积，导致切割边缘出现毛刺、尺寸偏差等问题，影响后续焊接与密封工序的质量

Benefits of technology

1.采用支撑组件和限位组件的组合布局，能够限制油箱的前后和上下移动，而压紧件通过固定块安装在工作台的两侧，可以从油箱毛坯的左右两侧同时施加均衡的压紧力，进而限制了油箱毛坯左右移动和翘起的趋势，通过限位组件与压紧件的配合，有效限制了油箱毛坯的六个自由度，确保在切割过程中油箱毛坯的稳固和移位，不仅提高了切割断面的质量，也极大消除了因工件松动带来的安全隐患。
