Technical Problem

[0005]本实用新型的目的是提供一种具有校正结构的机械零件焊接用夹持机构，通过夹持板、夹持架、中心螺杆、预夹紧板、校正架、双螺纹杆、校正底座和校正滚轮实现让该机械零件焊接用夹持机构具备了校正结构，这样的校正结构设计确保校正力均匀分布，实现零件焊接位置的自动中心定位，而且还能解决单侧校正导致的偏斜问题，这样长期使用下通过双螺纹杆同步驱动和滚轮接触式校正，解决了传统焊接夹具精度低、效率差、适用性窄的问题，还显著提升了焊接质量与生产效率的效果，以解决现有技术中机械零件焊接用夹持机构在使用过程中，由于缺少校正结构会导致需手动调整零件位置，这样容易出现焊缝偏移和虚焊等问题，而且需先焊接后修正，或采用试焊－调整－重焊的循环，这样生产效率也降低，长期使用下缺少校正结构，还会导致焊接废品率高、人工成本增加、机构可靠性下降，无法满足现代化精密制造需求的问题

Benefits of technology

本实用新型设置有夹持板、夹持架、中心螺杆、预夹紧板、校正架、双螺纹杆、校正底座和校正滚轮，当使用该机械零件焊接用夹持机构时，先扭动中心螺杆让预夹紧板抵触在机械零件的外部，对焊接夹持台上进行焊接的两个机械零件，先进行预夹紧，再推动两个进行焊接的机械零件朝着对接焊接板靠拢，让两个机械零件焊接的位置进行对接，然后让旋转的双螺纹杆带动两个外螺纹套朝着中心滑动，这样在外螺纹套的带动下，校正底座推动上方的上推板和校正滚轮对两个对接在一起的机械零件进行中心对准和校正，这样使得该机械零件焊接用夹持机构具备了校正结构，这样的校正结构设计确保校正力均匀分布，实现零件焊接位置的自动中心定位，而且还能解决单侧校正导致的偏斜问题，这样长期使用下通过双螺纹杆同步驱动和滚轮接触式校正，解决了传统焊接夹具精度低、效率差、适用性窄的问题，还显著提升了焊接质量与生产效率。
