使用方法主要包括以下四個(gè)環(huán)節(jié):
1 鉆孔
使用標(biāo)準(zhǔn)鉆頭鉆孔,鉆孔深度大于或等于鋼絲螺套安裝深度;注意不要將孔鉆成錐形,切屑不要掉入。鉆孔后锪孔不應(yīng)超過(guò)0.4 螺距深度,因?yàn)轱量走^(guò)大不利于鋼絲螺套的旋入。

2 攻絲
使用標(biāo)有規(guī)定螺紋規(guī)格的鋼絲螺套專(zhuān)用絲錐攻絲,攻絲的長(zhǎng)度必須超過(guò)鋼絲螺套長(zhǎng)度,對(duì)于通孔,要全部攻絲;攻絲的精度決定終標(biāo)準(zhǔn)內(nèi)螺孔的公差帶,使用者要適當(dāng)?shù)剡x擇攻絲方法和潤(rùn)滑,盲孔攻絲要適當(dāng)用力, 以防折斷絲錐。攻絲后,螺紋孔應(yīng)清理,一般用壓縮空氣噴槍吹,盲孔時(shí)還應(yīng)使用帶徑向孔的長(zhǎng)噴槍自下而上清理, 也可以用清洗的方法清理螺紋孔。螺紋孔精度高時(shí),應(yīng)用專(zhuān)用鋼絲螺套底孔塞規(guī)進(jìn)行檢查?!?/span>
3 安裝
在一般情況下應(yīng)用手工安裝器進(jìn)行鋼絲螺套安裝。鋼絲螺套放入裝工具內(nèi),使安裝柄嵌入導(dǎo)桿槽內(nèi)轉(zhuǎn)動(dòng)安裝工具手柄使鋼絲螺套旋入螺孔,并使其距表面有0.25-0.75 圈空螺紋。少量安裝鋼絲螺套時(shí)和M14×2 以上粗牙鋼絲螺套安裝時(shí)可采用“T ”型開(kāi)槽或螺紋頭簡(jiǎn)易工具安裝,并注意不要在鋼絲螺套安裝柄上施加較大的軸向力以防‘亂扣’ 。鋼絲螺套安裝后,為檢查所形成的標(biāo)準(zhǔn)內(nèi)螺紋孔精度等級(jí),可用相應(yīng)的級(jí)別塞規(guī)檢驗(yàn)。
4 去柄
對(duì)有折斷槽的鋼絲螺套,旋入螺孔后應(yīng)將安裝柄去除,需用去柄工具。通孔時(shí),要將鋼絲螺套安裝柄折斷,一般用沖斷器對(duì)準(zhǔn)安裝柄,用 200g 左右的榔頭猛打一下即可去除,對(duì)于 M18×2.5 以上的粗牙鋼絲螺套和 M14×1.25 以上的細(xì)牙鋼絲螺套 , 用尖嘴鉗上下彎曲安裝柄就能折斷,然后將斷下來(lái)的安裝柄從螺孔中取出即可。
一、鋼絲螺套專(zhuān)用絲錐
鋼絲螺套專(zhuān)用絲錐用于加工鋼絲螺套安裝孔的專(zhuān)用內(nèi)螺紋,結(jié)構(gòu)尺寸依照國(guó)家標(biāo)準(zhǔn)《細(xì)柄機(jī)用和手用絲錐》GB3464-83要求制造,材料為W18Cr4V,可機(jī)用也可手用,根據(jù)其使用范圍可分為輕合金機(jī)用螺紋護(hù)套絲錐、手用螺紋護(hù)套絲錐,普通鋼機(jī)用螺套絲錐、手用螺套絲錐,特種螺套絲錐三種。
1、輕合金機(jī)、手螺紋護(hù)套絲錐
用于加工鋁、鎂合金以及銅合金等有色金屬合金,螺距在2.5mm以下為單支絲錐,螺距大于等于2.5mm為雙支。
標(biāo)記示例:STd × p ST 為螺紋護(hù)套專(zhuān)用內(nèi)螺紋代號(hào)
用于在輕合金上加工安裝規(guī)格為8×1.25鋼絲螺套底孔螺紋的專(zhuān)用絲錐,標(biāo)記為:ST8×1.25(ST為鋼絲螺套專(zhuān)用內(nèi)螺紋代號(hào))。
2、普通鋼機(jī)、手用螺紋護(hù)套絲錐
用于加工鋼、鑄鐵、鑄鋼等金屬材料上的內(nèi)螺紋,是雙支絲錐。
3、特種絲錐
可根據(jù)用戶需要設(shè)計(jì)、制造各種特殊品種的螺紋底孔絲錐,例如在軟鋁,紫銅上攻絲的機(jī)用、手用擠壓絲錐,單支普通鋼攻絲的專(zhuān)用機(jī)用絲錐、不銹鋼攻絲絲錐、用于盲孔的平底絲錐、螺旋槽絲錐、螺尖絲錐等。鋼絲螺套絲錐、螺紋護(hù)套絲錐的選擇
◆直槽螺紋護(hù)套絲錐通用性很強(qiáng),通孔或盲孔、有色金屬或黑色金屬都可使用,價(jià)格也便宜,但質(zhì)量較差。螺紋護(hù)套直槽絲錐
◆螺旋槽螺紋護(hù)套絲錐比較適合加工盲孔螺紋,加工時(shí)切屑向后排出。在加工黑色金屬時(shí),螺旋角選擇的少小一點(diǎn),大約一般在 30 度左右,可以保證螺旋齒的強(qiáng)度。在加工有色金屬時(shí),螺旋角選擇的少大一點(diǎn),大約一般在 45 度左右,這樣切削時(shí)可以鋒利一些。
◆擠壓絲錐比較適合加工有色金屬,尤其是鋁合金鑄件,它主是對(duì)金屬擠壓、變形、形成的內(nèi)螺紋。擠壓成形是非切削加工,采用擠壓成形工藝加工出的螺紋孔,抗拉、抗剪強(qiáng)度高,加工表面的粗糙度也較好,但擠壓絲錐底孔要求較高,過(guò)大,強(qiáng)度不夠;過(guò)小容易造成絲錐斷裂。
◆ 螺尖絲錐比較適合加工通孔螺紋,加工時(shí)切削向前排出。固芯部尺寸較大,強(qiáng)度較好,切削力較大,所以對(duì)加工有色金屬、不銹鋼、黑色金屬效果都很好。
二、鋼絲螺套安裝工具
鋼絲螺套安裝工具就是鋼絲螺套安裝扳手,也叫鋼絲螺套旋入工具。
鋼絲螺套安裝扳手使用方法就是將鋼絲螺套放入專(zhuān)用鋼絲螺套安裝工具內(nèi),使安裝柄嵌入導(dǎo)桿槽內(nèi),轉(zhuǎn)動(dòng)鋼絲螺套安裝工具手柄使鋼絲螺套旋入螺孔。其安裝原理就是使鋼絲螺套通過(guò)一段引導(dǎo)螺紋,迫使外徑收縮,以便順利裝入底孔。安裝時(shí)注意不可在鋼絲螺套上施加較大的軸向力,以防"亂扣"。
鋼絲螺套安裝扳手分為分為手動(dòng)及半自動(dòng)兩種。
● 手動(dòng)鋼絲螺套安裝工具
手動(dòng)鋼絲螺套安裝扳手,主要有套筒型安裝扳手和簡(jiǎn)易鋼絲螺套安裝扳手兩種。
(1)套筒型螺紋護(hù)套安裝扳手
用于手動(dòng)安裝 ST2 × 0.4以上規(guī)格螺紋護(hù)套 標(biāo)記方法: ST d × p
(2)簡(jiǎn)易螺紋護(hù)套安裝扳手
簡(jiǎn)易螺紋護(hù)套安裝工具有螺紋頭、光桿兩種。用于少量安裝,一般維修、實(shí)驗(yàn)時(shí)用,操作時(shí)不易安裝,鋼絲螺套容易報(bào)廢。
● 半自動(dòng)安裝扳手
半自動(dòng)安裝扳手有氣動(dòng)、電動(dòng)兩種,具有**、快速,安裝定位準(zhǔn)確的特點(diǎn),用于批量鋼絲螺套的安裝或在裝配生產(chǎn)線上使用。
三、鋼絲螺套安裝柄去除工具(沖斷器)
沖斷器主要作用就是用來(lái)折斷鋼絲螺套安裝尾柄。
鋼絲螺套在安裝后,一般通孔都要求將尾柄去除掉,具體方法是用沖斷器對(duì)準(zhǔn)安裝柄,用200g的榔頭猛打一下,即可去除,對(duì)于18X2.5以上的粗牙絲套和14X1.25以上的細(xì)牙絲套,用尖嘴鉗上下彎曲安裝柄就能折斷。
四、鋼絲螺套取出工具---卸套器
鋼絲螺套在安裝過(guò)程中出現(xiàn)問(wèn)題需要取出,應(yīng)當(dāng)使用專(zhuān)用鋼絲螺套取出工具---卸套器,將卸套器放入鋼絲螺套孔內(nèi),對(duì)準(zhǔn)手柄用榔頭猛擊一下,用手加力按下手柄反螺紋旋轉(zhuǎn)即可取出鋼絲螺套。
五、鋼絲螺套專(zhuān)用內(nèi)螺紋塞規(guī)—底孔塞規(guī)
鋼絲螺套裝配的精度等級(jí),取決于攻制的螺紋孔精度;在對(duì)鋼絲螺套安裝精度要求較高的情況下,可以在用鋼絲螺套專(zhuān)用絲錐(ST絲錐)攻牙后,在鋼絲螺套裝配旋入螺孔之前,用鋼絲螺套底孔塞規(guī)測(cè)量螺紋孔,對(duì)螺紋孔的精度進(jìn)行檢測(cè),以此保證鋼絲螺套安裝后形成的內(nèi)螺紋是標(biāo)準(zhǔn)的螺紋。
鋼絲螺套底孔塞規(guī)也叫ST塞規(guī),螺紋護(hù)套塞規(guī),鋼絲螺套塞規(guī)
鋼絲螺套塞規(guī)用于檢驗(yàn)鋼絲螺套安裝前的底孔尺寸,一般在對(duì)工作精度要求較高或用來(lái)鑒別絲錐是否磨損時(shí)使用,分為單頭整體螺紋塞規(guī)及雙頭插柄底孔塞規(guī),I級(jí)精度。
1、單頭整體鋼絲螺套塞規(guī)
用于檢驗(yàn)ST2-ST5小規(guī)格鋼絲螺套安裝前內(nèi)孔螺紋。
2、雙頭插柄鋼絲螺套塞規(guī)
用于檢驗(yàn)ST5以上規(guī)格鋼絲螺套安裝前內(nèi)螺紋。
