那位高手知道螺纹塞规、环规的检验方法和使用方法？ 2011-05-10 11:01提问者：?xiejingmxh?|浏览次数：3531次 我来帮他解答 满意回答 2011-05-15 20:56 你要检测什么螺纹啊 公制的 还是美标的UNC UNF UNEF NPT NPSF ANPT ACME STI BSPP BSPT NPSM 什么标准的啊 具体点 使用螺纹校对规来检测螺纹环规校对程序首先校对塞规建立被校对环规的尺寸。校对塞规也被叫做检验规。检验“check”字样会打在柄部和头部。他们应是修正型（truncated type）,既有全形齿，又有修正齿部分。他们的三元素（中径，半角，全角）均需按W级精度制造。W级允许校对环规更接近产品极限的最大值和最小值，使得零件有最大合格比。校对塞规在使用前必须检查是否公差正确，表面无划痕，堵塞，或其他缺陷。如在校对规或环规表面发现有损伤，则应弃用，因为在可能的紧密啮合中，其中一只上的划痕可能刮伤或损坏另一只的表面校对规在有效中径部分必需保持合适的直线度。他们在实际使用中，前端可能磨损较快。无论如何请使用以下推荐程序以帮助延长校对塞规的直线度寿命1. Thoroughly clean both the ring and the setting plug in a good cleaning solution and jet blow dry ( or clean ultrasonically). Then visually inspect to make sure all foreign material in the thread has been removed and no nicks or burrs are present.彻底清洗环规与校对塞规，并吹干或超声波清洗。然后观察所有螺纹内的外来物确认已被清除，并无划痕和毛刺。2. Lubricate the setting plug with a thin film of light viscosity oil before inserting into the ring gage.用带清油的胶片润滑校对塞规3. Turn the locking screw counter-clockwise until it is loosened.反时针拧松锁紧螺钉4. Turn the adjusting screw clockwise, which opens the ring to a larger pitch diameter than the setting plug.顺时针调节螺钉，这使环规开口，并使中径比校对塞规的大。5. Turn the ring gage onto the setting plug all the way to the back (full form section) so that approximately one thread extends beyond the last thread of the setting plug. (This promotes more uniform wear over the entire thread length of the plug.)旋转环规进入塞规后部（全形齿部分），使塞规的大约一牙留在外面（这使整个塞规螺纹长度有教标准的磨损）6. Turn the adjusting screw counter-clockwise until there is a slight drag between the ring and setting plug.反向旋转调节螺钉，直到塞环规间有轻轻的拉动7. Turn the locking screw counter-clockwise until tight. This locks the adjusting screw so that the size of the ring gage remains fixed. There should now be a noticeable drag between ring and setting plug. Operations 6 and 7 may have to be repeated more than once to obtain the proper drag fit.反向旋转锁紧螺钉，拧紧。这将锁定调节螺钉，并固定环规尺寸。现在应看到塞环规间有可见的拉动。步骤＃7和＃8可能要重复多次，以取得合适的拉动配合8. Turn the ring gage from the fu
