压装质量验证常用量具与仪器

核心结论:在线曲线判定不能替代独立的尺寸与力值验证。配置合适的量具,是把「设备说合格」变成「实测也合格」的必要环节。

质量判定的关键指标

尺寸验证:千分表/百分表、高度规、卡尺与专用检具,用于复核压入深度与端面齐平度。

力值验证:标准测力仪用于压力传感器多点标定,覆盖常用工艺力段。

异常识别要点

  • 位置验证:外置量表比对控制器显示值,复核重复定位精度与热漂移。
  • 形位验证:涉及垂直度、同轴度的工序需配相应检具,如转子压入类 2 丝 / 3 丝级要求。
  • 所有量具应纳入计量管理并在有效期内使用,记录可作为客户过程审核证据。

压装曲线常用判据

判据 识别的异常 设置要点
贴合点位置 工件未坐实、定位漂移 以压力突升为触发,作为曲线原点
上升段斜率 漏装、材料偏软、配合过盈异常 按合格件样本统计边界
峰值力 过压、卡阻、错装 与传感器量程匹配,避免长期使用满量程
终点位置 未压到位、过压 位置控制下直接读取
上下包络窗口 综合过程异常 取 30–50 件合格件建立基线

常见问题

有曲线判定还要量具吗

要,曲线是过程证据,量具是对过程结果的独立验证。

标定周期怎么定

按使用强度、客户要求与量具管理规定执行,高频工位宜缩短。
