螺紋環(huán)規(guī)是檢測(cè)工件外螺紋并且在折算成中經(jīng)和實(shí)際中經(jīng)的專業(yè)綜合量具,在具體的外形上包括止規(guī)和通規(guī)兩部分。可能有些人不明白為什么其會(huì)包括兩部分,在這里就給大家做個(gè)簡(jiǎn)單的介紹,希望看過(guò)本文之后你能有個(gè)大致的認(rèn)識(shí)。首先具有外螺紋的工件,在外徑上會(huì)對(duì)其有個(gè)誤差的限制,無(wú)論是大于這個(gè)誤差還是小于這個(gè)誤差都是不合格的。因此在對(duì)工件的外螺紋進(jìn)行實(shí)際檢查過(guò)程中,就要考慮到大于這個(gè)公差或者小于這個(gè)公差兩種情況。正是基于這點(diǎn)需要,檢測(cè)螺紋的量規(guī)才會(huì)具有兩部分,一是通規(guī),另一個(gè)是止規(guī)。通規(guī)顧名思義就是能夠整個(gè)通過(guò)外螺紋的量規(guī),其是螺紋量規(guī)檢查外螺紋是否查過(guò)公差的量具。而止規(guī)則檢查的是負(fù)公差,只有將止規(guī)套在外螺紋中,且其不會(huì)旋進(jìn)去才是符合要求的產(chǎn)品。
通規(guī)檢查的是外螺紋是否大于正公差,因?yàn)槿绻笥谡钜?,那么通?guī)就不能旋進(jìn)去并且很好通過(guò)去。而止規(guī)則檢查的是負(fù)公差,因?yàn)槿绻饴菁y的外徑尺寸小于負(fù)公差,其也能很好通過(guò)通規(guī),用止規(guī)對(duì)其檢測(cè)時(shí),也會(huì)很順利通過(guò)止規(guī)。由此可見(jiàn),螺紋量規(guī)無(wú)論是檢查正公差還是負(fù)公差,都能很好達(dá)到目的。而廠家在制作外螺紋的時(shí)候,也應(yīng)該以標(biāo)準(zhǔn)量規(guī)為量具,確保順利通過(guò)通規(guī)的同時(shí),也能止步于止規(guī)。這就是為什么檢查外螺紋的量規(guī)會(huì)具有兩部分的原因。
螺紋環(huán)規(guī)使用完畢后,應(yīng)及時(shí)清理干凈測(cè)量部位附著物,存放在規(guī)定的量具盒內(nèi)。
生產(chǎn)現(xiàn)場(chǎng)在用量具應(yīng)擺放在工藝定置位置,輕拿輕放,以防止磕碰而損壞測(cè)量表面。 嚴(yán)禁將量具作為切削工具強(qiáng)制旋入螺紋,避免造成早期磨損。可調(diào)節(jié)螺紋環(huán)規(guī)嚴(yán)禁非計(jì)量工作人員隨意調(diào)整,確保量具的準(zhǔn)確性。環(huán)規(guī)長(zhǎng)時(shí)間不用,應(yīng)交計(jì)量管理部門妥善保管。
在用量具應(yīng)在每個(gè)工作日用校對(duì)塞規(guī)計(jì)量一次。
Thread ring gauge is a professional comprehensive measuring tool for detecting the external threads of workpiece and converting them into intermediate and actual meridians. It includes stop gauge and conventional gauge in specific shape. Maybe some people don't understand why it includes two parts. Here's a brief introduction. I hope you can have a general understanding after reading this article. Firstly, the workpiece with external threads will have an error limitation on its external diameter, whether greater or less than this error is unqualified. Therefore, in the actual process of inspecting the external thread of the workpiece, it is necessary to take into account two situations: greater tolerance or less tolerance. It is precisely because of this need that the gauge for thread detection has two parts, one is the general gauge, the other is the stop gauge. As the name implies, a general rule is a gauge that can pass through the external thread entirely. It is a gauge that checks whether the external thread has checked tolerance or not. The stop rule checks the negative tolerance. Only when the stop gauge is sleeved in the outer thread, and it will not be screwed in, can the product meet the requirements.
The general inspection is whether the external thread is larger than the positive tolerance, because if it is larger than the requirement of the positive tolerance, the general rules can not be screwed in and passed well. The check of stop rule is negative tolerance, because if the outer diameter of the thread is smaller than negative tolerance, it can pass the general rules well, and it will pass the stop rule smoothly when it is tested with stop gauge. It can be seen that the thread gauge, whether checking positive tolerance or negative tolerance, can achieve its purpose very well. And manufacturers in the production of external threads, should also take the standard gauge as a measuring tool to ensure smooth passage of the regulations, but also stop at the stop. This is why the gauge for checking the external thread has two parts.
After the thread ring gauge is used, the attachment of the measuring part should be cleaned up in time and stored in the prescribed measuring box.
The measuring tools used in the production site should be placed in the fixed position of the process and handled lightly so as to prevent the measurement surface from being damaged by knocking. It is strictly forbidden to force the measuring tool into the thread as a cutting tool to avoid early wear and tear. Adjustable threaded ring regulations prohibit non-metering staff from adjusting at will to ensure the accuracy of measuring tools. If the ring gauge is not used for a long time, it should be handed over to the metrological management department for proper storage.
The gauge should be calibrated once every working day.
