塞板(ban)又叫(jiao)孔(kong)用(yong)(yong)(yong)片(pian)型(xing)(xing)(xing)塞規對大(da)于φ65以(yi)上(shang)的(de)(de)(de)(de)塞規可(ke)以(yi)做(zuo)成單頭不(bu)全型(xing)(xing)(xing)和孔(kong)用(yong)(yong)(yong)片(pian)型(xing)(xing)(xing)塞規。塞板(ban)主要(yao)是測(ce)是內孔(kong)徑(jing)的(de)(de)(de)(de)檢具。另可(ke)以(yi)來(lai)圖(tu)訂做(zuo)非標片(pian)型(xing)(xing)(xing)孔(kong)用(yong)(yong)(yong)塞規。Tr梯(ti)形(xing)量規，G管螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)及美標螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)量規.螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)塞規用(yong)(yong)(yong)于綜合(he)(he)(he)檢驗(yan)(yan)內螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)環規用(yong)(yong)(yong)于綜合(he)(he)(he)檢驗(yan)(yan)外螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)。螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)量規通(tong)(tong)規模擬被(bei)(bei)測(ce)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)的(de)(de)(de)(de)最大(da)實體牙型(xing)(xing)(xing)，檢驗(yan)(yan)被(bei)(bei)測(ce)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)的(de)(de)(de)(de)作(zuo)用(yong)(yong)(yong)中(zhong)(zhong)(zhong)徑(jing)是否(fou)超過其最大(da)實體牙型(xing)(xing)(xing)的(de)(de)(de)(de)中(zhong)(zhong)(zhong)徑(jing)，并(bing)同時(shi)檢驗(yan)(yan)底徑(jing)實際尺寸是否(fou)超過其最大(da)實體尺寸。檢驗(yan)(yan)方法：如果被(bei)(bei)測(ce)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)能夠與(yu)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)通(tong)(tong)規旋(xuan)合(he)(he)(he)通(tong)(tong)過，且(qie)與(yu)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)止規不(bu)完全旋(xuan)合(he)(he)(he)通(tong)(tong)過(螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)止規只允許(xu)與(yu)被(bei)(bei)測(ce)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)兩(liang)段旋(xuan)合(he)(he)(he)，旋(xuan)合(he)(he)(he)量不(bu)得超過兩(liang)個螺(luo)(luo)(luo)(luo)距(ju))，就表明被(bei)(bei)測(ce)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)的(de)(de)(de)(de)作(zuo)用(yong)(yong)(yong)中(zhong)(zhong)(zhong)徑(jing)沒有超過其最大(da)實體牙型(xing)(xing)(xing)的(de)(de)(de)(de)中(zhong)(zhong)(zhong)徑(jing)，且(qie)單一中(zhong)(zhong)(zhong)徑(jing)沒有超出其最小實體牙型(xing)(xing)(xing)的(de)(de)(de)(de)中(zhong)(zhong)(zhong)徑(jing)，那么就可(ke)以(yi)保(bao)證旋(xuan)合(he)(he)(he)性和連接強度，則被(bei)(bei)測(ce)螺(luo)(luo)(luo)(luo)紋(wen)(wen)(wen)中(zhong)(zhong)(zhong)徑(jing)合(he)(he)(he)格。

  螺紋中徑說白了，就是螺紋的公稱直徑，即一般所說的螺紋“M**”里的*代表的數值，它是一個介于大徑(外螺紋為牙頂的直徑，內螺紋為牙底直徑)和小徑(同大徑含義相反)之間的一個直徑。

  最大實體牙型，顧名思義，就是螺紋的牙型制造出來能達到的最大實體，即實際加工制造出來的比理論設計時，在誤差范圍能且在體積上能達到的最大值的狀態。

  軸類(lei)零(ling)件(外螺紋)的最大(da)實體尺(chi)寸體現在(zai)直(zhi)(zhi)徑(jing)(jing)上(shang)，就(jiu)是(shi)軸直(zhi)(zhi)徑(jing)(jing)大(da)于設計尺(chi)寸;孔(kong)累(lei)零(ling)件(內螺紋)的最大(da)實體尺(chi)寸體現在(zai)直(zhi)(zhi)徑(jing)(jing)上(shang)，就(jiu)是(shi)孔(kong)的直(zhi)(zhi)徑(jing)(jing)小于設計尺(chi)寸。
