參閱圖1,為一現有的螺絲1,包含一螺頭11、一自該螺頭11沿一軸向延伸的桿身12,及一個一體連接於該桿身12相反於該螺頭11之一端的鑽尾13。該桿身12包括一呈螺旋環繞的螺牙121,及至少一凹設且斜向延伸的排屑槽122。當該螺絲1藉由該鑽尾13而執行鑽攻工件時,隨著該螺牙121逐漸螺入該鑽尾13於工件上鑽出的孔洞,使工件產生的殘屑將經由該至少一排屑槽122逐漸排出,避免殘屑累積於該螺牙121及該鑽尾13之間而影響鑽攻。Referring to Fig. 1, it is an existing
螺攻元件的適用範疇相當廣泛,除了可能應用於各種材質的工件,甚至可能應用於由二種以上材質所製成的複合工件。若該至少一排屑槽122無法隨著鑽攻過程而提供足夠的排屑量,即便可因應單一材質所製成的工件,但在使用於複合工件的場合時,則有可能在鑽攻至第二種硬度較高之材質時,因累積之殘屑已堵塞於該至少一排屑槽122中進而阻塞於該鑽尾13,且影響該鑽尾13的切削效果,因而使該螺絲1失去預期的鑽攻效果,不但可能需要施加越來越大的扭力來達成鑽攻目的,甚至可能因所施加的過大外力使工件產生龜裂,進而使工件在後續使用時產生安全疑慮,就鑽攻作業的過程而言也將大幅影響到作業效率。The scope of application of screw tapping components is quite wide. In addition to being applied to workpieces of various materials, it may even be applied to composite workpieces made of more than two materials. If the at least one
因此,本發明之目的,即在提供一種能降低鑽攻時所需施加之扭力及快速排屑、容屑,以確保鑽攻作業之順暢而提高作業效率的螺絲。Therefore, the purpose of the present invention is to provide a screw that can reduce the torque required to be applied when drilling and tap, and quickly remove and contain chips, so as to ensure smooth drilling and tapping operations and improve working efficiency.
於是,本發明螺絲,包含一螺頭、一自該螺頭沿一軸線延伸的桿身、一連接於該桿身相反於該螺頭之一端的攻鑽件、一螺旋環設於該桿身的螺牙,及至少一凸設於該桿身的肋條。其中,該至少一凹口跨越該肋條而與該桿身的該至少一凹槽相連通。Thus, the screw of the present invention comprises a screw head, a shaft extending from the screw head along an axis, a tapping member connected to the end of the shaft opposite to the screw head, and a helical ring arranged on the shaft screw teeth, and at least one rib protruding from the shaft. Wherein, the at least one notch straddles the rib and communicates with the at least one groove of the shaft.

Wherein, the at least one notch straddles the reverse tooth and communicates with the at least one groove of the shaft.
再者,本發明螺絲,包含一螺頭、一自該螺頭沿一軸線延伸的桿身、一連接於該桿身相反於該螺頭之一端的攻鑽件、一螺旋環設於該桿身的螺牙,及多個形成於該桿身且以該軸線為軸而呈環狀排列的螺旋凸紋。其中,該至少一凹口跨越該等螺旋凸紋而與該桿身的該至少一凹槽相連通。Furthermore, the screw of the present invention comprises a screw head, a shaft extending from the screw head along an axis, a tapping member connected to the end of the shaft opposite to the screw head, and a helical ring arranged on the shaft The screw thread of the shaft, and a plurality of helical ribs formed on the shaft and arranged in a ring shape with the axis as the axis. Wherein, the at least one notch communicates with the at least one groove of the shaft across the spiral ribs.
本發明之功效在於:在該螺絲鑽攻的過程中,由該螺牙配合該攻鑽件切削而產生的殘屑,能大量容置於該凹槽中。在產生的殘屑能確實被容置的情況下,則不容易殘留於該螺牙或該攻鑽件上,藉此維持該攻鑽件的功能性,有效降低鑽攻時產生的摩擦力,同時也減少所需施加的扭力。其中,本發明螺絲可為單一材質或複合材質螺絲,皆可達成上述功效。The effect of the present invention lies in that: during the process of screw drilling and tapping, a large amount of debris produced by the cutting of the thread and the tapping part can be accommodated in the groove. In the case that the generated debris can be accommodated, it is not easy to remain on the thread or the tapping part, thereby maintaining the functionality of the tapping part and effectively reducing the friction generated during drilling. It also reduces the torque required to be applied. Wherein, the screw of the present invention can be a single material or a composite material screw, both of which can achieve the above effects.
在本發明被詳細描述之前,應當注意在以下的說明內容中,類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.
參閱圖2,本發明螺絲之一第一實施例,包含一螺頭2、一自該螺頭2沿一軸線L延伸的桿身3、一連接於該桿身3相反於該螺頭2之一端的攻鑽件4,及一螺旋環設於該桿身3的螺牙5。Referring to Fig. 2, a first embodiment of the screw of the present invention includes a
該桿身3包括一以垂直該軸線L之方向往內凹設的凹槽30、一形成該凹槽30的槽段31、一介於該槽段31與該螺頭2之間的上段32,及一介於該槽段31與該攻鑽件4之間的下段33。其中,該凹槽30是以該軸線L為軸而完整環繞,且該凹槽30沿該軸線L方向延伸的長度,需依照被鑽攻物件的厚度做適當調整,以求達到最佳效果。簡而言之,被鑽攻物件越厚,原則上該凹槽30的延伸長度越長,則可達成較佳的容屑效果,但延伸長度以不超過被鑽攻物件的厚度為準。The
另外,本第一實施例的主要特點之一,為該攻鑽件4具有一以平行該軸線L之方向延伸而呈凹陷狀的凹口40,該凹槽30是與該凹口40相連通。值得特別說明的是,該凹槽30的凹陷深度可自由調整,只要凹陷深度較該桿身3之牙底徑要低即可發揮功效。然而,雖然該凹槽30的深度越深則效果越佳,但仍須考量該桿身3的扭斷強度,故凹陷的深度是參考製造材質的扭斷強度為限,亦即凹陷之深度仍須維持本發明的整體性,限度需以能承受選用材質之機械性質的要求即可。此外,該凹口40的底部可呈現弧形、直角,或者呈現任一角度的凹陷,皆可達到預期效果。In addition, one of the main features of the first embodiment is that the
參閱圖2與圖3,使用本第一實施例鑽攻由一木板91及一金屬板92相互疊合所構成的一工件9,當該攻鑽件4已攻透該木板91而開始鑽攻該金屬板92時,因該攻鑽件4的凹口40與該凹槽30連通,鑽攻該木板91所產生的殘屑會大量容置於該凹槽30中,避免該凹口40及該螺牙5因累積殘屑而失去刃口,有利於進一步鑽攻材質更堅硬之該金屬板92。值得特別說明的是,在該桿身3之該下段33利用該攻鑽件4及該螺牙5鑽攻時,會使鑽攻的該工件9形成一鑽孔900,由於該鑽孔900的徑向寬度會較形成該凹槽30之該槽段31的徑向寬度要寬,因此形成於該槽段31的凹槽30勢必得以發揮容置殘屑的功能,並且因形成於該槽段31之凹槽30的徑寬較該鑽孔900要窄而不會直接接觸壁面,能大幅減少繼續螺攻時的摩擦力,有效降低鑽攻時的阻力及所需施加的扭力,優化該第一實施例的鑽攻性能。Referring to Fig. 2 and Fig. 3, use this first embodiment to drill and attack a
參閱圖4,為本第一實施例的其中一種實施態樣,差別在於該攻鑽件4的該凹口40相較於該軸線L呈傾斜,當此種實施態樣鎖入被鑽攻物件時,具傾斜角的該凹口40相對於如圖2、3所示之平行該軸線L的該凹口40而言,更能有效率地將殘屑向外排出,或者往該凹槽30傳送。Referring to Fig. 4, it is one of the implementation styles of the first embodiment, the difference is that the
參閱圖4-1至圖4-12,為本第一實施例的另外多種實施態樣,該攻鑽件4除了如圖4所呈現之常用的單面單一凹口40之外,也能採用例如圖4-1至圖4-7所示的雙面各單一凹口40且該凹口40與該凹槽30相連通、單面數道凹口40且該等凹口40均有連通該凹槽30、單面數道凹口40且僅有一凹口40連通該凹槽30、雙面數道凹口40至少有一凹口40連通該凹槽30,及螺旋凹口40。另外,值得特別說明的是,上述具多道凹口40者可僅一凹口40與該凹槽30相連通,亦可同時多道凹口40與該凹槽30相連通,在此僅呈現部分實施例,而不以圖4、圖4-1至圖4-8所示為限,舉凡類似應用皆屬本案之專利範圍。而鑽攻尾的型態,可採用如圖4、圖4-1至圖4-6所呈現之尖尾狀,或者如圖4-7所呈現之螺旋狀等等其它型態的鑽攻尾,以因應不同的鑽攻需求。再者,該桿身3還可以如圖4-8、圖4-10,及圖4-11所示,包括二個在該螺牙5與該凹槽30之間分別以遠離該軸線L之相反方向凸伸的翅片39,或是如圖4-9所示包括二個在該凹槽30與該攻鑽件4之間分別以遠離該軸線L之相反方向凸伸的翅片39,或是如圖4-12所示包括二個在該桿身3之上段32的螺牙5間(下段33的螺牙5間亦可)分別以遠離該軸線L之相反方向凸伸的翅片39,藉以增加鑽攻中段時之擴孔切削能力,且不以上述型態為限;其中,請參閱圖4-8所示,該二翅片39之外徑d’是小於該螺牙5之外徑D為較佳的使用方式。Referring to Fig. 4-1 to Fig. 4-12, it is another variety of implementation styles of the first embodiment. In addition to the commonly used single-sided
參閱圖5,為本第一實施例的另一種實施態樣,針對適用於容屑的該凹槽30,實質上只要在該桿身3形成凹陷狀,即可發揮容置殘屑的效果。考量到可因應之製程的多元性,以及大量製造時的效率需求,該凹槽30除了如圖2呈現之以例如車、銑、削、輾、搓之加工手法形成與該桿身3有明顯段差之型態以外,亦可採用以例如鍛打、輾造、搓造、旋扭、沖壓、車修的技術手法而形成相對平滑連續凹面的方式來形成該凹槽30,同樣可發揮預期之容屑功效。Referring to FIG. 5 , it is another implementation of the first embodiment. As for the
參閱圖6與圖7,為本第一實施例的另外兩種實施態樣,針對用以容屑的該凹槽30,該攻鑽件4的樣貌形式不受限制,製作過程中可採用鍛打、輾造、搓造、旋扭、沖壓、車修、切削等等技術手法使該凹口40直接與該凹槽30相連通,不但可節省工序也可藉此降低成本。就實質功效而論,也確實可達成本第一實施例之容屑、排屑、降低扭力的功效。Referring to Fig. 6 and Fig. 7, it is another two implementation styles of the first embodiment. For the
參閱圖8與圖9,為本發明螺絲的一第二實施例,本第二實施例與該第一實施例的差別在於:該桿身3包括二個凹槽30,該等凹槽30是以該軸線L為軸而等角設置。要特別說明的是,本第二實施例也可以是形成三個以上所述凹槽30的型態,形成有更多所述凹槽30時,該等凹槽30也是以該軸線L為軸而呈環狀間隔分布。相較於該第一實施例而言,本第二實施例也能透過該等凹槽30產生排屑、容屑、降低阻力及扭力的相同功效。除此之外,由於本第二實施例的該等凹槽30容積較該第一實施例要少,故雖然總容屑量較少,但能適度提高整體結構強度,以因應其它使用場合的需求。Referring to Fig. 8 and Fig. 9, it is a second embodiment of the screw of the present invention. The difference between this second embodiment and the first embodiment is that: the
參閱圖10,為本發明螺絲的一第三實施例,與該第一實施例的差別在於:該螺牙5包括一設置於該下段33的外牙部51,也就是說,該螺牙5僅形成於該桿身3的該下段33。由於透過該凹槽30能有效在鑽攻過程中降低所需施加的扭力,且執行鑽攻時主要都是透過形成於該下段33的外牙部51來鎖入,故在所要求的拉拔力較低的情況下,只需要該外牙部51即可達成鎖附工件的力量。另外,定義該凹槽30沿平行該軸線L延伸的一段長度Z,所述長度Z是大於等於該桿身3之該上段32的牙底徑Y,以確保該凹槽30能具有一定的容積。Referring to FIG. 10 , it is a third embodiment of the screw of the present invention. The difference from the first embodiment is that the
參閱圖11與圖12,為本發明螺絲的一第四實施例,與該第三實施例的差別在於:該螺牙5還包括一設置於該槽段31的內牙部52。其中,該內牙部52的外徑d是小於或等於該外牙部51的外徑D。在鑽攻的過程中,除了能在該凹槽30累積一定程度的殘屑以外,透過該內牙部52亦可增加抓附被鎖工件的力量,藉此提高拉拔力。要另外強調的是,雖然如圖11所繪示之該內牙部52是均勻形成於該凹槽30中,但在實際實施時,亦可依照實際需求調整該內牙部52分布在該凹槽30中的位置,例如亦可如圖12所呈現僅延伸至該凹槽30中的一半長度,並不以圖11所繪示之型態為限。Referring to FIG. 11 and FIG. 12 , it is a fourth embodiment of the screw of the present invention. The difference from the third embodiment is that the
參閱圖13,為本發明螺絲的一第五實施例,與該第四實施例的差別在於:該螺牙5包括一設置於該槽段31的內牙部52,及一設置於該上段32及該下段33的外牙部51。也就是說,本第五實施例相較於該第四實施例而言,在該桿身3之該上段32也形成有該外牙部51,能在鑽攻的深度較深時,進一步提升拉拔力,也能優化鎖緊能力。Referring to FIG. 13 , it is a fifth embodiment of the screw of the present invention. The difference from the fourth embodiment is that the
參閱圖14,為本發明螺絲的一第六實施例,與該第一實施例的差別在於:本第六實施例還包含至少一凸設於該桿身3之該下段33的肋條62。所述肋條62在本第六實施例執行鑽攻作業時,能在該螺牙5鎖入的同時產生擴孔效果,藉此降低該桿身3後續螺入鑽出之鑽孔的阻力,也減少後續需切削的範圍,故能有效達成省力及減屑的功效。特別值得說明的特色是,當該肋條62設置於該槽段31與該下段33之間時,本第六實施例鎖入時造成的擴孔,能使工件與該上段32的牙底處產生間隙,形成新的容屑空間,以配合鑽攻而產生額外的容屑效果。此外,另要特別說明的是,所述肋條62除了較佳是形成於該下段33以外,即便形成於該桿身3的其它位置,也足以發揮擴孔效果,並不以圖14所繪示為限。要強調的是,當該肋條62設置於該凹槽30與該下段33之間,並使該凹口40的長度跨越該肋條62而與該凹槽30連通,為本第六實施例較佳的運用方式。Referring to FIG. 14 , it is a sixth embodiment of the screw of the present invention. The difference from the first embodiment is that the sixth embodiment further includes at least one
參閱圖15,為本發明螺絲的一第七實施例,與該第一實施例的差別在於:本第七實施例還包含一形成於該桿身3之該下段33且螺旋延伸方向與該螺牙5相反的反向牙63。本第七實施例的該反向牙63,並不會配合該螺牙5產生同向的鎖入效果,故能與如圖14所示之該第六實施例產生相同的擴徑效果,藉此達成與該第六實施例相同的省力、減屑功效。其中,若是該凹口40延伸跨越該等反向牙63,並與該凹槽30相通,則可達成本第七實施例較佳的使用。要特別說明的是,所述反向牙63除了較佳是形成於該下段33以外,即便形成於該桿身3的其它位置,也足以發揮擴孔效果,且反向牙63的數目可為數個,並不以圖15所繪示為限。Referring to Fig. 15, it is a seventh embodiment of the screw of the present invention. The difference with the first embodiment is that the seventh embodiment also includes a helical extension direction and the
參閱圖16,為本發明螺絲的一第八實施例,與該第一實施例的差別在於:本第八實施例還包含多個形成於該桿身3之該下段33且以該軸線L為軸而呈環狀排列的螺旋凸紋64。同理,該等螺旋凸紋64也能在本第八實施例鑽攻時產生擴孔效果,藉此與該第六實施例及該第七實施例達成相同的功效。其中,若是該凹口40延伸跨越該等螺旋凸紋64並與該凹槽30相通,則可達成本第八實施例較佳的使用。同樣的,所述螺旋凸紋64除了較佳是形成於該下段33以外,即便形成於該桿身3的其它位置,也足以發揮擴孔效果,並不以圖16所繪示為限。Referring to FIG. 16 , it is an eighth embodiment of the screw of the present invention. The difference from the first embodiment is that the eighth embodiment also includes a plurality of
參閱圖17,為本發明螺絲的一第九實施例,本發明螺絲之所以能在鑽攻時發揮減少所需施加之扭力的功效,主要來自於該凹槽30額外產生的容屑效果,故只要在該桿身3上形成有該凹槽30,即可達成本發明之主要訴求。本第九實施例與該第一實施例的差別在於:該凹槽30與該螺頭2沿該軸線L的距離,小於該凹槽30與該攻鑽件4沿該軸線L的距離。也就是說,該凹槽30是形成於相對該攻鑽件4要更靠近該螺頭2的位置,仍得以達成本發明螺絲主要訴求之優化容屑、排屑功能,藉此降低鑽攻時之扭力,讓鑽攻的過程能更加順暢。因此,配合不同的鑽攻需求,也可以適度調整該凹槽30的位置,並不影響本發明所欲達成的基本功效。Referring to Fig. 17, it is a ninth embodiment of the screw of the present invention. The reason why the screw of the present invention can reduce the required torsion force during drilling and tapping is mainly due to the additional chip holding effect generated by the
參閱圖18,為本發明螺絲之一第十實施例,本第十實施例與該第一實施例的差別在於:該桿身3的該凹槽30是自該螺頭2延伸至該攻鑽件4。透過完整延伸於該桿身3的該凹槽30,能大幅增加容屑空間,藉此因應深度較深的鑽攻。Referring to FIG. 18 , it is a tenth embodiment of the screw of the present invention. The difference between the tenth embodiment and the first embodiment is that the
參閱圖19,為本發明螺絲之一第十一實施例,本第十一實施例與該第一實施例的差別在於:該桿身3的該凹槽30是自該螺頭2延伸至該攻鑽件4,且該螺牙5還包括一設置於該槽段31的內牙部52。透過完整延伸於該桿身3的該凹槽30,能大幅增加容屑空間,且透過該內牙部52亦可增加抓附被鎖工件的力量,藉此提高拉拔力,同樣能因應深度較深的鑽攻。Referring to FIG. 19 , it is an eleventh embodiment of the screw of the present invention. The difference between this eleventh embodiment and the first embodiment is that the
參閱圖20,為本發明螺絲之一第十一實施例的另一種實施態樣,差別在於:該桿身3的該下段33並未形成外牙部51,除了能達到與圖19所示之螺絲相同之效果以外,亦能提供另外一種實施態樣。Referring to Fig. 20, it is another embodiment of an eleventh embodiment of the screw of the present invention. The difference is that the
參閱圖21,為本發明螺絲之一第十二實施例,本第十二實施例與該第一實施例的差別在於:該桿身3包括多個沿該軸線L方向間隔分布的凹槽30,及多個連通該等凹槽30之連通口34,相較於該第一實施例而言,本第十二實施例也能透過該等增加的凹槽30及該等連通口34而增加排屑及容屑量,進而更有效達到降低阻力及扭力的相同功效,而該凹槽30之數量可依照應用需求或依使用者指定,而不以圖21所示為限。Referring to FIG. 21 , it is a twelfth embodiment of the screw of the present invention. The difference between this twelfth embodiment and the first embodiment is that the
參閱圖22,為本發明螺絲之一第十三實施例,本第十三實施例與該第十二實施例的差別在於:該等凹槽30是沿該軸線L方向間隔分布且彼此不相連通,相較於該第一實施例而言,本第十三實施例同樣也能透過該等增加的凹槽30配合該凹口40產生排屑、容屑、降低阻力及扭力的相同功效。Referring to FIG. 22 , it is a thirteenth embodiment of the screw of the present invention. The difference between the thirteenth embodiment and the twelfth embodiment is that the
綜上所述,本發明螺絲在鑽攻的過程中,由於該至少一個凹口40與該凹槽30相互連通的設計,由該攻鑽件4配合該攻鑽件4上之凹口40切削而產生的殘屑,能大量容置於該凹槽30中,在產生的殘屑能確實被容置的情況下,則不容易殘留於該攻鑽件4及該凹口40,無論採用何種型態的該攻鑽件4,皆可維持該攻鑽件4或該凹口40得以有繼續切割的刃口,同時也有效降低鑽攻時產生的摩擦力,藉此也減少所需施加的扭力,故確實能達成本發明之目的。In summary, during the drilling and tapping process of the screw of the present invention, due to the design that the at least one
