面板主体260还设置有显示器安装孔2621、功率调节旋钮通孔2631、行程刻度槽2641和两个升降按钮通孔2642，显示器安装孔2621位于第一平板部262的中部位置，功率调节旋钮通孔2631位于弧形拱起部263的中部位置，行程刻度槽2641沿竖向设置在第二平板部264，两个升降按钮通孔2642分别位于行程刻度槽2641的两侧。由图1和图2可知，显示器安装孔2621用于安装显示器3，显示器3用于显示焊接参数，功率调节旋钮通孔2631用于安装功率调节旋钮4，功率调节旋钮4用于调节换能器的输出功率，升降按钮通孔2642用于安装升降按钮5，升降按钮5用于控制发振筒22上下运动。
由图3和图4可知，第一限位块242还设置有微调指针246和指针安装槽2423，微调指针246安装在指针安装槽2423内，微调指针246与行程刻度槽2641配合设置。通过设置行程刻度槽2641，可便于指示发振筒的行程，便于调节。
本实施例的超声波焊接机在进行行程调节时，先移动升降支架21，使发振筒22与待焊接工件的距离靠近一定距离后固定升降支架21，接着，使用行程微调组件24对发振筒22的行程进行调节，在调节行程微调组件24时，利用微调旋钮2431圆周上的100等分刻度和行程刻度槽2641的高度刻度，进行调节观察，可更直观的目视化微调的距离，提高精度。
由上述可知，本发明超声波焊接机的机头组件2通过设置行程微调组件24，可对发振筒22的行程进行微调，提高行程调节精度，确保发振筒22与待焊接工件距离，避免过压。同时，第一限位块243设置有限位通槽2431，第二限位块244设置有限位凸柱2441，限位凸柱2441与限位通槽2431限位配合，可避免发振筒22在限位过程中发生晃动，提高发振筒22行进的稳定性。此外，机头面板26通过设置加强筋部261，可进一步提高面板主体260的强度，设置有弧形拱起部263，可防止面板弯曲，从而避免机头面板26变形。从外，加强筋部261、第一平板部262、弧形拱起部263和第二平板部264一体成型可提高面板主体260的稳固强度。
需要说明的是，以上仅为本发明的优选实施例，但发明的设计构思并不局限于此，凡利用此构思对本发明做出的非实质性修改，也均落入本发明的保护范围之内。
本发明的机头组件和超声波焊接机适用于超声波焊接的应用场合，应用本发明的产品，通过行程微调组件可对发振筒的行程进行微调，提高行程调节精度，确保发振筒与待焊接工件距离，避免过压，同时，第一限位块设置有限位通槽，第二限位块设置有限位凸柱，限位凸柱与限位通槽限位配合，可避免发振筒在限位过程中发生晃动，提高发振筒行进的稳定性。本发明通过设置行程微调组件，同时在第一限位块设置有限位通槽，第二限位块设置有限位凸柱，限位凸柱与限位通槽限位配合，不仅给人们带来使用上的便利，更是极大的提高了超声波焊接机的精度以及发振筒行进的稳定性。
