請參閱圖1,本發明實施方式提供之螺紋緊固組件100,用於將複數待裝配零件組裝於一起。螺紋緊固組件100包括插芯10及用於與插芯10相配合之螺合件30。螺合件30大致呈中空結構,其用於 穿設所述複數待裝配零件,並與所述複數待裝配零件相螺合。插芯10插設於螺合件30內,使螺合件30之外徑增大,從而使螺紋緊固組件100與所述複數待裝配零件緊密配合,進而將所述複數待裝配零件牢固地組裝於一起。 Referring to Figure 1, a threaded fastening assembly 100 is provided for assembling multiple components to be assembled together. The threaded fastening assembly 100 includes a ferrule 10 and a threaded member 30 for mating with the ferrule 10. The screw member 30 has a substantially hollow structure and is used for The plurality of parts to be assembled are threaded and screwed with the plurality of parts to be assembled. The ferrule 10 is inserted into the screwing member 30 to increase the outer diameter of the screwing member 30, so that the threaded fastening assembly 100 is closely matched with the plurality of parts to be assembled, thereby firmly fixing the plurality of parts to be assembled. Assembled together.
在本實施方式中,插芯10大致呈圓柱桿狀,螺合件30為六角頭螺栓。 In the present embodiment, the ferrule 10 is substantially in the shape of a cylindrical rod, and the screwing member 30 is a hexagonal head bolt.
螺合件30包括頭部32及形成於頭部32一端之螺桿34。 The screw member 30 includes a head portion 32 and a screw 34 formed at one end of the head portion 32.
具體在圖式之實施例中,頭部32為外六角螺栓頭。可以理解,頭部32可以為內六角頭、圓頭或其他形狀之螺栓頭。 Specifically in the illustrated embodiment, the head 32 is a hexagonal bolt head. It will be appreciated that the head 32 can be a hexagonal head, a rounded head or other shaped bolt head.
螺桿34凸伸形成於頭部32之一端,其上形成有螺紋部341,螺紋部341用以與所述複數待裝配零件相螺合。在本實施方式中,螺桿34整體大致呈圓臺桿狀,其外徑沿遠離頭部32之方向逐漸減小。具體而言,螺桿34靠近頭部32之一端之外徑大於螺桿34遠離頭部32之一端之外徑。螺紋部341形成於螺桿34之外周,且由螺桿34之大致中部位置延伸至螺桿34遠離頭部32之一端。 The screw 34 is formed at one end of the head 32, and a threaded portion 341 is formed thereon, and the threaded portion 341 is screwed with the plurality of parts to be assembled. In the present embodiment, the screw 34 as a whole has a substantially truncated rod shape, and its outer diameter gradually decreases in a direction away from the head portion 32. Specifically, the outer diameter of the screw 34 near one end of the head 32 is greater than the outer diameter of the screw 34 away from one end of the head 32. The threaded portion 341 is formed on the outer circumference of the screw 34 and extends from a substantially central position of the screw 34 to one end of the screw 34 away from the head 32.
請同時參閱圖2至圖4,螺合件30沿自身軸向貫穿開設有中心孔36,螺桿34於螺紋部341上開設有膨脹間隙38。 Referring to FIG. 2 to FIG. 4 simultaneously, the screwing member 30 is provided with a central hole 36 extending through the axial direction thereof, and the screw 34 is provided with an expansion gap 38 on the threaded portion 341.
具體在圖示之實施例中,中心孔36大致呈圓臺孔,其貫通螺合件30之頭部32及螺桿34。中心孔36用於收容插芯10。中心孔36之孔徑自頭部32延伸至螺紋部341之方向逐漸減小,其最大孔徑大於插芯10之直徑,最小孔徑小於插芯10之直徑,以便於中心孔36牢固地收容插芯10。 Specifically, in the illustrated embodiment, the central bore 36 is generally a truncated bore that extends through the head 32 of the screw member 30 and the screw 34. The center hole 36 is for receiving the ferrule 10. The aperture of the central hole 36 gradually decreases from the head 32 to the threaded portion 341, and the maximum aperture is larger than the diameter of the ferrule 10, and the minimum aperture is smaller than the diameter of the ferrule 10, so that the central hole 36 securely receives the ferrule 10. .
膨脹間隙38由螺紋部341靠近頭部32之一端開設,並沿螺桿34之 軸線方向延伸至螺紋部341遠離頭部之一端,且與中心孔36相連通。在本實施方式中,膨脹間隙38之數量為二。二膨脹間隙38分別設置在螺紋部341之相對二側,從而把螺紋部341分割成二瓣。 膨脹間隙38使螺紋部341具有一定之彈性,螺紋部341之二瓣能夠在外力之驅動下相互靠攏或相互遠離,從而使螺紋部341之外徑相應地減小或增大。 The expansion gap 38 is opened by the threaded portion 341 near one end of the head 32 and along the screw 34 The axial direction extends to the threaded portion 341 away from one end of the head and communicates with the central bore 36. In the present embodiment, the number of expansion gaps 38 is two. The two expansion gaps 38 are respectively disposed on opposite sides of the threaded portion 341, thereby dividing the threaded portion 341 into two lobes. The expansion gap 38 provides a certain elasticity to the threaded portion 341, and the two lobes of the threaded portion 341 can be moved closer to each other or away from each other by the external force, so that the outer diameter of the threaded portion 341 is correspondingly reduced or increased.
在本實施方式中,膨脹間隙38大致為長條形槽。膨脹間隙38之寬度自靠近所述頭部32之一端延伸至所述膨脹間隙38遠離所述頭部32之一端之方向逐漸減小。具體而言,膨脹間隙38靠近頭部32之一端之寬度大於膨脹間隙38遠離頭部32之一端。當螺紋部341在外力作用下沿徑向擴張時,膨脹間隙38遠離頭部32之一端之寬度隨之增大。 In the present embodiment, the expansion gap 38 is substantially an elongated groove. The width of the expansion gap 38 gradually decreases from a direction near one end of the head 32 to a direction in which the expansion gap 38 is away from one end of the head 32. Specifically, the width of the expansion gap 38 near one end of the head 32 is greater than the expansion gap 38 away from one end of the head 32. When the threaded portion 341 is radially expanded by an external force, the width of the expansion gap 38 away from one end of the head 32 increases.
由於插芯10之直徑大於中心孔36之最小孔徑,插芯10插入中心孔36中時,插芯10之端部抵推中心孔36之內壁。隨著插芯10持續插入,在插芯10抵推下,螺紋部341被膨脹間隙38分割之二瓣漸漸張開並相互遠離,從而使螺紋部341之外徑增大。 Since the diameter of the ferrule 10 is larger than the minimum aperture of the center hole 36, when the ferrule 10 is inserted into the center hole 36, the end of the ferrule 10 abuts against the inner wall of the center hole 36. As the ferrule 10 continues to be inserted, the ferrule 10 is pushed down, and the two lobes of the threaded portion 341 divided by the expansion gap 38 are gradually opened and moved away from each other, thereby increasing the outer diameter of the threaded portion 341.
請同時參閱圖5及圖6,本發明實施方式之螺紋緊固組件100應用於零件200之鎖合緊固,為便於說明,本說明書以一零件200作實例說明。具體而言,零件200上開設有螺紋孔210,螺紋孔210用於與螺紋部341相配合。使用螺紋緊固組件100時,首先,將螺合件30旋入螺紋孔210中,並使螺紋部341與螺紋孔210相螺合。然後,將插芯10插入中心孔36內。在插芯10之抵推下,螺紋部341沿徑向膨脹,使得螺紋部341之螺牙與螺紋孔210之螺牙緊密配合或過盈配合,從而螺紋緊固組件100與零件200牢固地組裝於一起 。可以理解,若零件200之數量為二或二以上,則使螺紋緊固組 件100插設於複數零件200中,複數零件200同時與螺紋緊固組件100緊密配合或過盈配合,從而使複數零件200通過螺紋緊固組件100牢固地組裝於一起。 Referring to FIG. 5 and FIG. 6 simultaneously, the screw fastening assembly 100 of the embodiment of the present invention is applied to the locking and fastening of the component 200. For convenience of description, the present specification uses a component 200 as an example for illustration. Specifically, the component 200 is provided with a threaded hole 210 for engaging with the threaded portion 341. When the threaded fastening assembly 100 is used, first, the screwing member 30 is screwed into the threaded hole 210, and the threaded portion 341 is screwed with the threaded hole 210. Then, the ferrule 10 is inserted into the center hole 36. Under the urging of the ferrule 10, the threaded portion 341 is radially expanded, so that the thread of the threaded portion 341 is tightly fitted or interference fit with the thread of the threaded hole 210, so that the threaded fastening assembly 100 is firmly assembled with the part 200. Together . It can be understood that if the number of parts 200 is two or more, the thread fastening group is made. The piece 100 is inserted into the plurality of parts 200, and the plurality of parts 200 are simultaneously mated or interference fit with the threaded fastening assembly 100 such that the plurality of parts 200 are securely assembled together by the threaded fastening assembly 100.
本發明實施方式之螺紋緊固組件100,其螺合件30之螺紋部341上開設有膨脹間隙38,使螺紋部341能夠在外力之作用下沿自身徑向收縮或膨脹。螺紋緊固組件100在緊固複數待裝配之零件200時,首先使螺合件30與零件200進行螺紋配合,再通過插芯10使螺紋部341沿徑向膨脹以與零件200緊密配合或過盈配合,從而能夠使複數零件200通過螺紋緊固組件100牢固地組裝於一起,不易鬆動。另外,由於中心孔36大致為圓臺孔,其孔徑自頭部32延伸至螺紋部341之方向逐漸減小,插芯10在中心孔36中之插入深度決定了螺紋部341之膨脹程度,使得螺紋部341能夠與具有一定製造誤差之螺紋孔210相配合,從而使螺紋緊固組件100能夠適用於製造精度較低之零件200。 In the screw fastening assembly 100 of the embodiment of the present invention, the threaded portion 341 of the screw member 30 is provided with an expansion gap 38, so that the thread portion 341 can be contracted or expanded in the radial direction by itself under the action of an external force. When tightening the plurality of parts 200 to be assembled, the threaded fastening assembly 100 firstly screws the screwing member 30 with the part 200, and then expands the threaded portion 341 radially by the ferrule 10 to closely fit or pass the part 200. The mating fit enables the plurality of parts 200 to be securely assembled together by the threaded fastening assembly 100 and is less prone to loosening. In addition, since the center hole 36 is substantially a circular hole, the hole diameter thereof gradually decreases from the head 32 to the thread portion 341, and the insertion depth of the ferrule 10 in the center hole 36 determines the degree of expansion of the thread portion 341, so that The threaded portion 341 can be mated with a threaded bore 210 having a manufacturing tolerance such that the threaded fastening assembly 100 can be adapted to produce a less accurate part 200.
進一步地,在本實施方式中,螺合件30由碳鋼製成。可以理解,螺合件30可以由不銹鋼、黃銅或其他金屬材料製成,以使本實施方式之螺合件30可以用於緊固金屬製成之零件。同樣可以理解之是,為適應於不同材料之待裝配零件或為滿足不同之需求,螺合件30還可以由其他材料製成。例如,當所述待裝配零件為塑膠製品時,螺合件30可以相應地由塑膠製成。當所述待裝配零件之緊固連接要求有一定韌性及一定剛性時,螺合件30也可以由塑膠製成。 Further, in the present embodiment, the screw member 30 is made of carbon steel. It will be appreciated that the screw member 30 can be made of stainless steel, brass or other metallic material so that the screw member 30 of the present embodiment can be used to fasten metal-made parts. It will also be appreciated that the screw member 30 can be made of other materials to accommodate different materials to be assembled or to meet different needs. For example, when the part to be assembled is a plastic product, the screwing member 30 can be made of plastic correspondingly. When the fastening connection of the component to be assembled requires certain toughness and certain rigidity, the screwing member 30 can also be made of plastic.
可以理解,螺紋部341上之膨脹間隙38之數量可以為一或複數,以 使螺紋部341在外力作用下能夠沿自身徑向收縮或擴張。 It can be understood that the number of the expansion gaps 38 on the threaded portion 341 can be one or plural to The threaded portion 341 can be contracted or expanded in its own radial direction by an external force.
可以理解,中心孔36之形狀不局限于上文所描述之圓臺孔結構,其可以設計為其他結構。例如,中心孔36可以為具有傾斜側壁之多邊形孔,並使中心孔36之孔徑自頭部32延伸至螺紋部341之方向逐漸減小,以使插芯10插入中心孔36內能夠抵推中心孔36之側壁,從而使螺紋部341能夠沿自身徑向收縮或擴張。 It will be appreciated that the shape of the central bore 36 is not limited to the truncated bore structure described above, which may be designed in other configurations. For example, the central aperture 36 can be a polygonal aperture having a sloped sidewall and the aperture of the central aperture 36 is tapered from the head 32 to the threaded portion 341 such that the ferrule 10 is inserted into the central aperture 36 to resist the center. The side walls of the holes 36 allow the threaded portion 341 to contract or expand radially in its own direction.
請同時參閱圖7,圖7示出了本發明另一實施方式之螺合件230之俯視圖。在本實施方式中,中心孔236為四邊形孔,其孔徑自頭部32延伸至螺紋部之方向逐漸減小。膨脹間隙238之數量為四,四膨脹間隙238分別開設于中心孔236之四棱邊上。可以理解,中心孔236可以為三角形孔、五邊形孔、六邊形孔、其他多邊形孔或不規則孔等,本說明書不作一一贅述。 Please refer to FIG. 7 at the same time. FIG. 7 shows a top view of the screw member 230 according to another embodiment of the present invention. In the present embodiment, the center hole 236 is a quadrangular hole whose hole diameter gradually decreases from the head 32 to the threaded portion. The number of expansion gaps 238 is four, and the four expansion gaps 238 are respectively formed on the four edges of the center hole 236. It can be understood that the central hole 236 can be a triangular hole, a pentagonal hole, a hexagonal hole, other polygonal holes or irregular holes, etc., and the description is not described in detail herein.
可以理解,插芯10之形狀不局限于上文所描述之圓柱桿狀結構,其可以設計為其他之結構,並使插芯10插入中心孔36中時,插芯10能夠抵推中心孔36之側壁,從而使螺紋部341能夠沿自身徑向收縮或擴張即可。 It can be understood that the shape of the ferrule 10 is not limited to the cylindrical rod structure described above, and it can be designed as another structure, and when the ferrule 10 is inserted into the center hole 36, the ferrule 10 can push against the center hole 36. The side walls are such that the threaded portion 341 can be contracted or expanded in its own radial direction.
例如,當中心孔236為圓臺孔時,插芯10可以設計為圓臺桿狀,並使插芯10之最小直徑小於中心孔36之最大孔徑,且大於中心孔36之最小孔徑。或者,當中心孔236為圓臺孔時,插芯10可以設計為三棱柱、四棱柱、五棱柱、其他多棱柱或不規則棱柱等,而使插芯10之最小外徑小於中心孔36之最大孔徑,且大於中心孔36之最小孔徑,從而使插芯10插入中心孔36中時,插芯10能夠抵推中心孔36之側壁,從而使螺紋部341能夠沿自身徑向收縮或擴張。 For example, when the center hole 236 is a truncated hole, the ferrule 10 can be designed as a truncated rod shape, and the minimum diameter of the ferrule 10 is smaller than the maximum diameter of the center hole 36 and larger than the minimum aperture of the center hole 36. Alternatively, when the central hole 236 is a circular hole, the ferrule 10 can be designed as a triangular prism, a quadrangular prism, a pentagonal prism, other polygonal prisms or irregular prisms, etc., so that the minimum outer diameter of the ferrule 10 is smaller than that of the central hole 36. The maximum aperture is greater than the minimum aperture of the central aperture 36 such that when the ferrule 10 is inserted into the central aperture 36, the ferrule 10 can push against the sidewall of the central aperture 36, thereby enabling the threaded portion 341 to contract or expand radially in its own direction.
再如,插芯10之形狀可以設計為與中心孔36之孔型相同之形狀,以使插芯10插設于中心孔36中時,插芯10之外周壁緊密地抵持于中心孔36之側壁,從而使螺紋部341膨脹時所受到之張力較為均勻。當中心孔36為三角形孔、五邊形孔、其他多邊形孔或不規則孔時,插芯10可以對應地設計為三棱柱、四棱柱、五棱柱、其他多棱柱或不規則棱柱等。甚至,插芯10之形狀可以不與中心孔36之形狀相吻合,其形狀可以設計為與中心孔36之孔型相異之形狀,僅需使得插芯10插入中心孔36中時,插芯10能夠抵推中心孔36之側壁,從而使螺紋部341能夠沿自身徑向收縮或擴張即可。 For another example, the shape of the ferrule 10 can be designed to be the same shape as the hole shape of the center hole 36, so that when the ferrule 10 is inserted into the center hole 36, the outer peripheral wall of the ferrule 10 closely abuts against the center hole 36. The side walls are such that the tension received by the threaded portion 341 is relatively uniform. When the central hole 36 is a triangular hole, a pentagonal hole, other polygonal holes or irregular holes, the ferrule 10 can be correspondingly designed as a triangular prism, a quadrangular prism, a pentagonal prism, other polygonal prisms or irregular prisms. Even, the shape of the ferrule 10 may not conform to the shape of the center hole 36, and its shape may be designed to have a shape different from that of the center hole 36, and only when the ferrule 10 is inserted into the center hole 36, the ferrule 10 can push against the side wall of the center hole 36, so that the thread portion 341 can be contracted or expanded in the radial direction of itself.
可以理解,螺桿34之外形不局限于上文所描述之圓臺桿狀,其可以設置為圓柱桿狀或其他之幾何形狀。 It will be appreciated that the outer shape of the screw 34 is not limited to the truncated cone shape described above, and may be provided in the shape of a cylindrical rod or other geometric shape.
可以理解,螺合件30可以為螺釘、螺柱等其他設置有外螺紋之螺紋緊固件。 It can be understood that the screwing member 30 can be a screw, a stud, or the like, and other threaded fasteners provided with external threads.
可以理解,膨脹間隙38之形狀可以不局限于上文所描述之長條形,其可以設計為其他形狀之槽。例如,膨脹間隙38可以設計為彎折或者彎曲開設於螺紋部341上之通槽,且使膨脹間隙38貫通螺紋部341之一端,以保證螺紋部341在外力作用下能夠沿自身徑向收縮或擴張即可。 It will be appreciated that the shape of the expansion gap 38 may not be limited to the elongated strips described above, which may be designed as slots of other shapes. For example, the expansion gap 38 may be designed to bend or bend the through groove formed in the threaded portion 341, and the expansion gap 38 is passed through one end of the threaded portion 341 to ensure that the threaded portion 341 can be radially contracted by itself under the action of an external force or Expand it.
