  5. 一种由去毛刺机专用气阀构成的真空工作平台，它包括去毛刺机真空工作平台，其特征是：所述去毛刺机真空工作平台的台面上开有多个负压吸气孔且负压吸气孔背面装有气阀，所述气阀的上阀体和与下阀体结合部设有用于关闭上阀体腔和下阀体腔通道的弹性阀芯片且弹性阀芯片在非工作状态下处于常开状态。
  6. 根据权利要求 5 所述的由去毛刺机专用气阀构成的真空工作平台，其特征是：所述上阀体阀腔直径小于下阀体阀腔直径，且在下阀体阀口四周形成供弹性阀芯片关闭的密封面，弹性阀芯片弹性小于负压吸力。
  7. 根据权利要求 5 所述的由去毛刺机专用气阀构成的真空工作平台，其特征是：所述上阀体上部和下部车有丝扣，下阀体上部内腔制有丝扣且与上阀下部旋接。
  8. 一种由去毛刺机专用真空工作平台构成的去毛刺机，它包括去毛刺机，其特征是：摇臂下端与真空工作平台台面呈转动插接配合，双轴电机通过手柄总成安装在气缸臂端部，双轴电机两端分别装有砂片刷头和抛光刷盘，所述去毛刺机中的真空工作平台的台面上开有多个负压吸气孔，负压吸气孔背面装有气阀且位于真空腔内，真空腔出口与吸尘腔连通，吸尘腔的门上装有轴流风机，吸尘腔由下机架支撑，真空泵通过管道与真空腔连通且由电控箱控制其工作与否，所述气阀的上阀体和与下阀体结合部设有用于关闭上阀体腔和下阀体腔通道的弹性阀芯片且弹性阀芯片在非工作状态下处于常开状态。
  9. 根据权利要求8所述的由去毛刺机专用气阀构成的真空工作平台，其特征是：所述上阀体阀腔直径小于下阀体阀腔直径，且在下阀体阀口四周形成供弹性阀芯片关闭的密封面，弹性阀芯片弹性小于负压吸力。
  10. 一种由去毛刺机专用气阀构成的真空工作平台的负压控制方法，其特征是：当上阀体口没有工件时，来自下阀体口的负压吸力将弹性阀芯片吸合在下阀体内腔阀口四周的密封台面上，此时上阀体腔与下阀体腔之间的气流通道被弹性阀芯片关闭，上阀体口没有负压气流产生；当上阀体口有工件时，来自下阀体口的负压气流使上阀体腔和下阀体腔形成真空状态，弹性阀芯片处于开启状态，来自下阀体口的负压气流直接通过真空工作平台上的负压吸气孔作用在工件上且将工件牢牢吸住。
