那位高手知道螺纹塞规、环规的检验方法和使用方法？

大家俗称的钢筋连接通止规，是包含：塞规 和 环规 。

一、

螺纹塞规：是测量内螺纹尺寸的正确性的工具。我们的塞规是专门检测钢筋连接套筒接头标准与否的专用工具。根据各工地所用套筒，牙型角有75度和60度两种，购买前请明确自己生产套筒的牙型角和螺距。螺纹塞规（栓规），同一个规格有两端作为一套同时使用，分别是通规和止规。1，用通规试拧，如果不能拧进就不合格，此时就不必要用止规了，因为它已经是不良品了。2，用通规试拧，如果能够拧进，再用止规拧，如果止规不能拧进或只拧进一两个牙规那就是合格。3，用通规试拧，如果能够拧进，再用止规拧，如果止规不能拧进或只能拧进一两个牙那就是合格。

二、

螺纹环规：是测量外螺纹尺寸的正确性的工具。我们的环规是专门检测钢筋连接丝头标准与否的专用工具。根据各工地所用套筒，牙型角有75度和60度两种，购买前请明确自己生产丝头的牙型角和螺距。螺纹环规用途供检查工件外螺纹尺寸是否合格用。每种规格规格螺纹环规又分为通规和止规两种，可分别单独购买或一并购买（标注价格为一个型号一种通规或者止规的价格）。检查时，只有当通规能与工件外螺纹旋合通过，而止规只与工件外螺纹部分旋合，且旋合量不超过两个螺距时，可判定该外螺纹合格；除此之外可判定外螺纹尺寸不合格。螺纹环规是检测外螺纹好坏的,它只是检测外螺纹是否可以符合使用要求。螺纹环规比如：检测M25螺距3.0的螺纹是否符合工艺要求是用M25*3.0的螺纹环规（有两种，一个是通规，另一为止规）通规通，止规止，证明加工的螺纹合格。

希望上面的说明可以帮到你。

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 full form section onto the truncated section of the front. The drag should be approximately the same to both sections, which insures good flank angle contact.
将环规从全形齿部分旋到前端修正齿部分。拉紧力应在两部分间基本一样，这才能保证牙形角是正确的

9. Remove the setting plug from the ring.
移走校对塞规
10. Now turn ring onto the setting plug 1-1/2 to 2 threads at the front. There should be some resistance or drag even at this short engagement. To test for taper or bellmouth, place the ring on its face on the workbench and test for shake or looseness with the setting plugs, being very careful not to damage these end threads
现在将环规旋入校对塞规前端1－1/2到2牙。这时会发现即使这样短的旋入，也会有一些阻力或拉力。为检验是否锥度或喇叭口，请将环规放在工作台上，用校对塞规轻摇，看其松紧度。请非常小心，不要伤到牙口。

11. Remembering the feel at the 1-1/2 to 2 thread engagements, turn the ring further onto the truncated section. The drag should remain approximately the same although it may be slightly greater at full engagement due to more flank contact.
记住旋入1－1/2到2牙时的感觉，并让环规继续在修正齿形部分前行。那种阻力应基本一致，虽然由于更多的齿面接触，会使阻力略有增加

12. Remove the ring from the setting plug and repeat operations 10 and 11 on the other side of the ring gage.
移下环规，调面，重复步骤＃10和＃11

13. The fit should be approximately the same on both sides of the ring to insure proper straightness.

Remember that if a setting plug is made or worn smaller at the front, it will falsely indicate taper or bellmouth in the ring gage. Setting plugs must be reasonably straight.
配合度应两面基本相同，以确保环规的直线度。
记住如果校对塞规尺寸做小了或前端磨损了，可能会错误的指示环规有锥度或喇叭口。校对塞规必须有精确的直线度
14. The minor diameter of a thread ring gage is normally checked with GO and NOT GO plain plug gages. These should be made to the minimum and maximum limits of the minor diameter of the ring gage, and to class X or XX cylindrical gage tolerance. The GO should enter through the ring and the NOT GO should not enter to assure that the minor diameter is correct after the ring is set to the proper pitch diameter.
螺纹环规的小径通常以光滑通止规检验。通常以环规小径的上下限，按X级或XX级公差制造光滑塞规公差
15. It is then standard practice to cover the adjusting screw and locking screw holes with sealing wax. This helps to prevent unauthorized tampering with the setting of the ring gage. Use green wax on the GO gage and red ax on the LO (NOT GO). This is not mandatory but provides an additional means of quick identification.
然后是标准步骤，用蜡封住螺纹孔。这以防未经授权去调整环规。用绿色封通规，红色封止规。这虽不是标准，但方便使用者快速判断
Tightness of Fit
松紧度
There are no established torque values for the degree of drag. Some judgment and common sense must be used. The resistance or drag for a small size gage should be less than for a large size gage. A spin fit is obviously much too loose. Too tight a fit could damage or cause excessive wear on the ring or the setting plug. On properly made gages with accurate lapped threads it takes very little change in size to effect a noticeable difference in drag. Two different setting plugs both within class W tolerance may feel entirely different in the same ring gage. (One could be too tight and the other too loose.)

In addition to pitch diameter variations, there may be slight different in the degree of drag at full engagement versus partial engagements. One should not expect absolute perfection. Within reason these
differences are not serious as both the ring and the setting plug may well be within their tolerances.
尚没有标准的拉力扭距值的规范，但仍有一些通用的判断方法。小规格规的阻力应小于大规格的。轻松打转显然是太松了。太紧则会伤害环规和校对规，或造成他们的过度磨损。良好质量的规，螺纹均经过精密研磨，所以尺寸变化很小，不致使阻力产生明显不同。同是W级公差的两个校对规，可能用在同一环规上，感觉可能完全不同。（一个可能太紧，另一个可能太松）
另外由于中径的变化，也可能在全部旋入与部分旋入时，阻力会略有不同。大家不要指望绝对的完美。在合理的范围内，这些不同并不要紧，因为环规与校对塞规此时仍很好的在公差内

Resetting of New Gages
重新设定新量规

It should be realized that a ring gage set to one setting plug does not necessarily fit another setting plug due to allowable tolerances. When ring gages and setting plugs are ordered together they should be matched properly at the factory before shipping. Sometimes the customer's setting plug is loaned to the manufacturer who matches them properly.

In other cases it may be necessary for the user to remove the sealing wax and reset the ring gage to his own setting plug -- following the recommended procedure outlined above.
这里要明确一个环规，由一个校对塞规设定后，由于公差的原因，并不需要必须适配另一校对塞规。
当环规与校对塞规被订购时，他们必须在工厂发货前调好。有时客户的校对塞规是从制造商租借的原配塞规。

其他情形，使用者就需解开蜡封，用自己的校对塞规重设环规――请按上述步骤进行。

一般来说检螺纹塞规是用三针配千分尺来检验。
螺纹环规是用校对规来检验。
