Description
本發明係有關於一種拆卸工具，特別是有關於一種用於拆卸受損固緊件之拆卸工具。The present invention relates to a disassembly tool, and more particularly to a disassembly tool for disassembling a damaged fastener.
非常多的裝置與機構中，皆需使用大量的緊固件(例如：螺栓、螺絲、螺帽、螺紋插件或類似元件)來結合各部件或與其他裝置結合。而緊固件通常係用如扳手等工具與緊固件之頭部或組接孔後用力旋扭而將其固緊或拆卸。然而，緊固件在多次固緊或旋鬆、或旋扭力道過大、或緊固件材質因素，常有可能被磨圓、損壞或變得無法順利拆卸。A large number of devices and mechanisms require the use of a large number of fasteners (eg, bolts, screws, nuts, threaded inserts, or the like) to join components or to incorporate other devices. The fasteners are usually fastened or disassembled by means of a tool such as a wrench and a head or a set of holes of the fastener. However, fasteners are often tightened or loosened, or the torque is too large, or fastener material factors, often rounded, damaged, or become unsuccessfully disassembled.
美國專利US 6,575,057揭示一種損壞連接件之移除工具，其一端係為供一驅動裝置連接驅動，另一端形成有複數個齒條，該等齒條係平行地沿移除工具之一長度方向中心軸不扭轉地對稱延伸，該等齒條區分為一前端部及一中間部，該前端部及該中間部各具有一固定截面尺寸，且該前端部之截面尺寸小於該中間部之截面尺寸，藉此使該前端部先進入損壞連接件孔內後，再利用該中間部之齒尖緣卡接於損壞連接件孔壁以進行拆卸。然而，該等齒條係為平行移除工具之長度方向中心軸直線延伸，並且該前端部及該中間部各具有固定之截面尺寸，如此該移除工具之齒條在拆卸時必須先用例如榔頭等工具將其敲入該損壞連接件，故作業上較為麻煩；且該移除工具之齒條於旋轉拆卸時無法更進一步地自動楔入該損壞連 接件，故容易相對該損壞連接件打滑旋轉而無法順利拆卸該損壞連接件。US 6,575,057 discloses a removal tool for damaging a connector, one end of which is connected for driving by a driving device, and the other end is formed with a plurality of racks which are parallel to the center of one of the lengths of the removing tool. The shaft extends symmetrically without twisting. The rack is divided into a front end portion and an intermediate portion. The front end portion and the intermediate portion each have a fixed cross-sectional dimension, and the front end portion has a cross-sectional dimension smaller than a cross-sectional dimension of the intermediate portion. Thereby, the front end portion is firstly inserted into the hole of the damaged connecting member, and then the tooth edge of the intermediate portion is engaged with the damaged connecting member hole wall for disassembly. However, the racks extend linearly in the longitudinal direction of the parallel removal tool, and the front end portion and the intermediate portion each have a fixed cross-sectional dimension, such that the rack of the removal tool must first be used, for example, when disassembling. The hammer and the like knock it into the damaged connector, so that the work is troublesome; and the rack of the removal tool cannot be automatically wedged into the damage even when it is rotated and disassembled. The connector is easy to slide relative to the damaged connector and the damaged connector cannot be successfully removed.
美國專利US 1,875,484揭示一種螺件卸除裝置，其於周面上延長度方向形成有多數肋部，該等肋部係為直線延伸，該螺件卸除裝置係藉該等肋部楔入螺件孔洞中而將螺件卸除。然而，該螺件卸除裝置之肋部係為直線延伸，因此同樣於旋轉拆卸時無法更進一步地自動楔入該損壞螺件，故容易相對損壞螺件打滑旋轉而無法順利拆卸該損壞螺件。US Patent No. 1,875,484 discloses a screw removing device in which a plurality of ribs are formed in the direction of extension of the circumferential surface, the ribs are linearly extended, and the screw removing device is wedged into the snail by the ribs The screw is removed from the hole. However, the ribs of the screw removing device are linearly extended, so that the damaged screw can not be automatically wedged even when the rotary detaching is performed, so that it is easy to relatively slip the rotating member and can not smoothly disassemble the damaged screw. .
中華民國專利TW I337116揭示一種損壞之螺栓及螺釘移除裝置，其包含一尖端、多數自該尖端延伸的槽口，該等槽口被由兩側截頭錐狀區域形成之牽引或咬合表面分離，該等表面在一側上以一非線性切削刃為界且在另一側上以一非切削刃為界，其中該等咬合表面可包含複數個鋸齒。然而，該等鋸齒並非沿移除裝置之長度方向中心軸以扭轉方向斜向延伸，因此同樣於旋轉拆卸時無法更進一步地自動楔入該損壞螺件，故容易相對損壞螺件打滑旋轉而無法順利拆卸該損壞螺件。The Republic of China Patent TW I337116 discloses a damaged bolt and screw removal device comprising a tip, a plurality of notches extending from the tip, the notches being separated by a traction or occlusal surface formed by frustoconical regions on both sides The surfaces are bounded on one side by a non-linear cutting edge and on the other side by a non-cutting edge, wherein the occlusal surfaces may comprise a plurality of serrations. However, the serrations do not extend obliquely in the twisting direction along the central axis of the lengthwise direction of the removing device. Therefore, the damaged screw member cannot be automatically wedged further during the rotational disassembly, so that it is easy to slip the rotating member relative to the damaged screw. Disassemble the damaged screw smoothly.
因此，有必要提供一種新穎且具有進步性之拆卸工具，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive disassembly tool to solve the above problems.
本發明之主要目的在於提供一種拆卸工具，可確實地楔入並抓固受損之固緊件而有效、快速地卸除受損之固緊件。SUMMARY OF THE INVENTION A primary object of the present invention is to provide a disassembly tool that can effectively wedge and secure a damaged fastener to effectively and quickly remove the damaged fastener.

While being driven, the second end portion 13 is integrally connected to the first end portion 12. In detail, the first end portion 12 has a polygonal (for example hexagonal) cross section and can be sleeved by a driving device such as the socket wrench 4 (as shown in FIG. 2); one of the first end portions 12 An end face traversing the central axis 11 of the longitudinal direction may also be formed with a connecting hole for inserting a driving device such as a hex wrench (as shown in FIGS. 3 and 4); the first end portion 12 may also have a polygonal cross section and The holes are assembled, and may be selectively connected to different driving devices, or may be combined with a driving device that cooperates with the first end portion 12 cross-sectional shape forming holes.
在本實施例中，該第一端部12朝該第二端部13方向定義一 實質平行於該長度方向中心軸11之第一方向，該第二端部13沿該第一方向錐縮並形成有多數齒肋14，明確地說，該第二端部13形成有六齒肋14，且兩兩齒肋14概位於該長度方向中心軸11相對二側。該等齒肋14沿該第一方向上係相對於該長度方向中心軸11以一扭轉方向斜向延伸，該扭轉方向相對地與該旋鬆方向同向。例如在圖1中，各該齒肋14係相對地由左至右斜下延伸，斜向角度較佳不大於45度，更佳係為5-30度，尤佳為15度以內，如此該等齒肋14可容易楔入該固緊件3且於扭轉方向上對受損之固緊件產生較大之作用力而利於拆卸。各該齒肋14具有一形成有多數第一斜齒15之徑向表面16，各該徑向表面16之第一斜齒15沿該第一方向上係相對於該長度方向中心軸11以該扭轉方向斜向延伸。例如在圖1中，各該第一斜齒15斜向角度較佳介於15-60度，更佳係為15-45度，又以15-30度為佳，如此該等第一斜齒15可容易楔入該固緊件3且於扭轉方向上對受損之固緊件產生較大之作用力而利於拆卸。In this embodiment, the first end portion 12 defines a direction toward the second end portion 13 In a first direction substantially parallel to the longitudinal direction central axis 11, the second end portion 13 is tapered in the first direction and formed with a plurality of tooth ribs 14, specifically, the second end portion 13 is formed with a six-tooth rib 14, and the two tooth ribs 14 are located on opposite sides of the central axis 11 in the longitudinal direction. The ribs 14 extend obliquely in the first direction with respect to the longitudinal direction central axis 11 in a twisting direction that is opposite to the unscrewing direction. For example, in FIG. 1, each of the ribs 14 extends obliquely downward from left to right, and the oblique angle is preferably not more than 45 degrees, more preferably 5-30 degrees, and even more preferably 15 degrees or less. The equal-tooth rib 14 can be easily wedged into the fastener 3 and exerts a large force on the damaged fastener in the twisting direction to facilitate disassembly. Each of the ribs 14 has a radial surface 16 formed with a plurality of first helical teeth 15, and the first helical teeth 15 of each of the radial surfaces 16 are along the first direction relative to the longitudinal central axis 11 The twisting direction extends obliquely. For example, in FIG. 1, each of the first helical teeth 15 has an oblique angle of preferably between 15 and 60 degrees, more preferably between 15 and 45 degrees, and further preferably between 15 and 30 degrees, such that the first helical teeth 15 The fastening member 3 can be easily wedged and exerts a large force on the damaged fastening member in the twisting direction to facilitate disassembly.
較佳地，相鄰齒肋14之間形成有一凹槽17，各該凹槽17之槽口寬度於該第一方向上沿其延伸方向漸減，以另一觀點解釋，各該齒肋14於該第一方向上沿其延伸方向上之截面寬度漸增，如此各該齒肋14在具有越小徑向尺寸之部分可提供較佳的結構強度、以及楔入和抓固該固緊件3之能力。可理解的是，各該凹槽17之槽口寬度於該第一方向上沿其延伸方向可為漸增。另外強調的是，該凹槽17可視為於一錐面凹設所形成，亦可視為相鄰齒肋14與一錐面所形成(相鄰齒肋14可視為由該錐面朝外凸出形成者)。Preferably, a groove 17 is formed between the adjacent ribs 14 , and the width of the notch of each of the grooves 17 is gradually decreased along the extending direction in the first direction, and the rib 14 is The cross-sectional width in the direction in which the first direction extends is increased, such that each of the ribs 14 provides better structural strength in the portion having a smaller radial dimension, and wedges and grips the fastener 3 Ability. It can be understood that the width of the notch of each of the grooves 17 can be gradually increased along the extending direction in the first direction. In addition, it is emphasized that the groove 17 can be formed as a conical recess, or can be regarded as an adjacent rib 14 and a tapered surface (the adjacent rib 14 can be seen as protruding outward from the tapered surface). Former).
在本實施例中，各該齒肋14之多數第一斜齒15係沿該齒肋 14延伸方向間隔地分佈。各該齒肋14之各第一斜齒15具有一徑向最外角緣18，各該徑向最外角緣18沿該第一方向上係相對於該長度方向中心軸11以該扭轉方向斜向延伸，各該徑向最外角緣18可提供楔入和抓固該固緊件3之能力。In this embodiment, a plurality of first helical teeth 15 of each of the ribs 14 are along the rib 14 extension directions are distributed at intervals. Each of the first helical teeth 15 of each of the ribs 14 has a radially outermost edge 18, and each of the radially outermost edges 18 is inclined in the first direction with respect to the longitudinal central axis 11 in the twisting direction. Extending, each of the radially outermost rims 18 provides the ability to wedge and grasp the fastener 3.
較佳地，相鄰第一斜齒15之間形成有一齒溝19，各該齒溝19之溝口寬度於該第一方向上沿其延伸方向漸減，以另一觀點解釋，各該第一斜齒15於該第一方向上沿其延伸方向上之截面寬度漸增，如此各該齒肋14在具有越小徑向尺寸之部分可提供較佳的結構強度、以及楔入和抓固該固緊件3之能力。各該齒肋14之每一於周向上完全橫跨徑向表面16(即橫跨相鄰二齒溝19之間)之第一斜齒15二端於該第一方向上的距離L1較佳係大於其相鄰齒溝19於該第一方向上的溝口寬度L2，如此同樣可提供較佳的楔入和抓固該固緊件3之能力。可理解的是，各該齒溝19之溝口寬度於該第一方向上沿其延伸方向可為漸增；該齒肋14之寬度係可依需求變化設計，例如具有較大之寬度、或具有較少的4個齒數(其他數量亦可)，如圖5所示。Preferably, a groove 19 is formed between the adjacent first helical teeth 15, and the width of the groove of each of the grooves 19 is gradually decreased along the extending direction of the first direction, and is explained by another point of view. The cross-sectional width of the teeth 15 in the direction in which they extend in the first direction is increased, such that each of the ribs 14 provides better structural strength in the portion having a smaller radial dimension, and wedges and grips the solid. The ability to tighten 3 pieces. Preferably, each of the ribs 14 has a distance L1 between the ends of the first helical teeth 15 that extend completely across the radial surface 16 (i.e., between the adjacent two-toothed grooves 19) in the first direction. It is greater than the width L2 of the groove of the adjacent groove 19 in the first direction, which also provides the ability to wedge and grasp the fastener 3. It can be understood that the width of the groove of each of the grooves 19 can be gradually increased along the extending direction in the first direction; the width of the rib 14 can be designed according to requirements, for example, having a larger width, or having There are fewer 4 teeth (other quantities are also available), as shown in Figure 5.
於本發明另一可能實施例中，各齒肋之二第一斜齒係可沿該齒肋延伸方向概呈平行地延伸，然各齒肋可具有更多第一斜齒。其中，該等第一斜齒於徑向上可具有高低落差，如此該等第一斜齒可先後地楔入該固緊件，可進一步提升抓固及釋放該固緊件之功效。In another possible embodiment of the present invention, the two first helical gears of each of the tooth ribs may extend substantially in parallel along the extending direction of the tooth rib, and each of the tooth ribs may have more first helical teeth. Wherein, the first helical teeth can have a height difference in the radial direction, such that the first helical teeth can be wedged into the fastening member in succession, which can further improve the effect of grasping and releasing the fastening member.
請參考圖6，其顯示本發明之第二較佳實施例。相較於第一實施例，在本實施例中之齒肋14’之一側面於該第一方向上形成有一長凹陷20，該長凹陷20係沿該齒肋14’延伸方向延伸且其槽口朝向該扭轉方 向。在該第二端部13之一截面中，各該齒肋14’之徑向表面16與長凹陷20相接處形成一角緣21，自該長度方向中心軸11朝該角緣21之一延伸線係通過該長凹陷20。透過如此結構，各該角緣21除可較容易楔入該固緊件外，更可於楔入該固緊件後提供更好得拖曳效果而防止打滑空轉，可確實將受損之該固緊件卸除。Please refer to Figure 6, which shows a second preferred embodiment of the present invention. Compared with the first embodiment, in one side of the tooth rib 14' in the embodiment, a long recess 20 is formed in the first direction, and the long recess 20 extends along the extending direction of the tooth rib 14' and has a groove. The mouth is facing the twisting side to. In a section of the second end portion 13, the radial surface 16 of each of the tooth ribs 14' forms a corner edge 21 with the long recess 20, and extends from the longitudinal direction central axis 11 toward one of the corner edges 21. The wire passes through the long recess 20. Through such a structure, each of the corner edges 21 can be easily wedged into the fastening member, and can provide a better towing effect after being wedged into the fastening member to prevent slipping and idling, and can surely damage the solid. Tight parts are removed.
請參考圖7，其顯示本發明之第三較佳實施例。相較於第一實施例，在本實施例中之桿體10’另包括一一體連接於該第一端部12與該第二端部13間之中段22，該中段22沿該第一方向錐縮並與該第二端部13滑順地連接，清楚地說，該中段22與該第二端部13可分別視為同一錐體之一區段。該中段22外周面形成有多數第二斜齒23，該等第二斜齒23沿該第一方向上係相對於該長度方向中心軸11以該扭轉方向斜向延伸，各該第二斜齒23之結構可如前述該第一斜齒之各種可能結構態樣。藉此，當該等第一斜齒楔入該固緊件後而該第二端部13完全沒入固緊件之孔洞、或該等第一斜齒未楔入該固緊件而該第二端部13完全沒入該孔洞時，即可透過該等第二斜齒23楔入該固緊件而將受損之該固緊件卸除。Please refer to FIG. 7, which shows a third preferred embodiment of the present invention. Compared with the first embodiment, the rod body 10' in this embodiment further includes an intermediate portion 22 integrally connected between the first end portion 12 and the second end portion 13. The middle portion 22 is along the first portion The direction tapers and is smoothly connected to the second end portion 13. Clearly, the middle portion 22 and the second end portion 13 can each be regarded as a section of the same cone. A plurality of second helical teeth 23 are formed on the outer circumferential surface of the middle portion 22, and the second oblique teeth 23 extend obliquely in the twisting direction with respect to the longitudinal direction central axis 11 in the first direction, and each of the second helical teeth The structure of 23 can be as described above for various possible structural aspects of the first helical teeth.

請配合參考圖1及8，當固緊件3與拆卸工具組接之孔洞31受磨損時，可直接將拆卸工具1***該孔洞31，並以扳手工具轉動該拆卸工具1，該拆卸工具1之齒肋14及其第一斜齒15斜下楔入該固緊件3，而可順利旋轉移除該固緊件3。Referring to FIGS. 1 and 8, when the hole 31 of the fastening member 3 and the disassembling tool assembly is worn, the disassembly tool 1 can be directly inserted into the hole 31, and the disassembly tool 1 is rotated by a wrench tool. The tooth rib 14 and its first helical tooth 15 are wedged downwardly into the fastening member 3, and the fastening member 3 can be smoothly rotated.
請配合參考圖1、9及10，當固緊件斷損僅剩螺桿身部32，可先利用一鑽頭5於該螺桿身部32端面鑽鑿一孔洞33，再將拆卸工具1***該孔洞33，並以扳手工具轉動該拆卸工具1，該拆卸工具1之齒肋14及 其第一斜齒15斜下楔入該螺桿身部32，而可順利旋轉移除斷損之固緊件。Referring to Figures 1, 9 and 10, when the fastening member has only the screw body 32, the hole 5 can be drilled into the end surface of the screw body 32 by a drill bit 5, and the removal tool 1 is inserted into the hole. 33, and rotating the disassembly tool 1 with a wrench tool, the rib 14 of the disassembly tool 1 and The first helical tooth 15 is wedged obliquely downward into the screw body 32, and the fastener can be smoothly rotated to remove the broken fastener.
在移除受損固緊件作業中，透過如前述該拆卸工具1之整體設計，僅需轉動該拆卸工具約15-30度(較佳設計僅需約15度或更少)，各該齒肋14以及各該第一斜齒15即已有效地楔入和抓固該固緊件而足以帶動該固緊件轉動，因此更有利於有效、快速地卸除受損之固緊件。In the operation of removing the damaged fastener, through the overall design of the disassembly tool 1 as described above, it is only necessary to rotate the disassembly tool by about 15-30 degrees (the preferred design only needs about 15 degrees or less), each of the teeth The rib 14 and each of the first helical teeth 15 have effectively wedged and grasped the fastening member enough to drive the fastening member to rotate, thereby facilitating the effective and rapid removal of the damaged fastening member.
要另外說明的是，發明人經實際製作各種拆卸工具並經實際測試驗證工作效果後發現，若拆卸工具不具如本案之齒肋或/及第一斜齒等結構，其工作效果不佳。It should be additionally noted that the inventors have actually produced various disassembling tools and verified the working results through actual tests, and found that if the dismantling tool does not have the structure such as the ribs and/or the first helical teeth of the present case, the working effect is not good.
如圖11所示之拆卸工具6，其於工作端61形成有多數間隔設置之齒肋62，每一齒肋62表面設有緊密分佈之多數螺紋63，該拆卸工具6加工複雜、加工時間較久、成本較高。並且，因緊密分佈之多數螺紋63相對於該拆卸工具6之一軸向以一極大之螺旋角度(相對於軸向之螺旋角度大於80度)繞設，故該拆卸工具6於卸除受損固緊件時，必須旋轉非常多圈後使得工作端61之大部分甚至全部螺紋皆楔入固緊件，直至該拆卸工具6之徑向周壁緊抵該固緊件而不相對該固緊件轉動時，才可帶動該受損固緊件旋鬆、卸除，因此卸除效率不佳。The detaching tool 6 shown in FIG. 11 is formed with a plurality of spaced apart ribs 62 at the working end 61. The surface of each rib 62 is provided with a plurality of closely spaced threads 63. The detaching tool 6 has complicated processing and processing time. Long time and high cost. Moreover, since the plurality of threads 63 closely distributed are wound with respect to one axial direction of the disassembly tool 6 at a maximum helix angle (the helix angle with respect to the axial direction is greater than 80 degrees), the disassembly tool 6 is damaged by the removal. When the fastening member is rotated, a large number of turns must be made so that most or even all the threads of the working end 61 are wedged into the fastening member until the radial peripheral wall of the removal tool 6 abuts against the fastening member without opposing the fastening member. When the rotation is performed, the damaged fastening member can be unscrewed and unloaded, so that the removal efficiency is not good.
另，如圖12所示之拆卸工具7，其於工作端71形成有多數由數個凹槽72所區隔之間隔設置且長短不一之齒肋73，各該齒肋73相對於該拆卸工具7之一軸向以一極小之螺旋角度(相對於軸向之螺旋角度小於15度)延伸，此種結構之齒肋73與凹槽72之交集點少，故定位於受損固緊件之卡槽的效果較差，卸除效率同樣不佳。In addition, as shown in FIG. 12, the detaching tool 7 is formed at the working end 71 with a plurality of ribs 73 which are spaced apart by a plurality of grooves 72 and have different lengths, and the ribs 73 are detached relative to the ribs 73. One of the tools 7 extends axially at a very small helical angle (the helical angle with respect to the axial direction is less than 15 degrees), and the intersection of the rib 73 and the groove 72 of this structure is small, so that the damaged fastener is positioned. The effect of the card slot is poor, and the removal efficiency is also poor.
綜上，本發明拆卸工具之錐形第二端形成有多數齒肋，各該 齒肋又具有多數斜向設置之第一斜齒，藉此，可確實地楔入並抓固該固緊件，可有效、快速地卸除受損之固緊件。In summary, the tapered second end of the disassembly tool of the present invention is formed with a plurality of ribs, each of which The rib has a plurality of first oblique teeth disposed obliquely, whereby the fastening member can be surely wedged and grasped, and the damaged fastener can be effectively and quickly removed.
此外，將該等齒肋或/及該等第一斜齒變化設計成具有適當的尺寸，可提升其結構強度。In addition, the ribs or/and the first helical teeth are designed to have appropriate dimensions to enhance their structural strength.
綜上所述，本發明拆卸工具之整體結構設計、實用性及效益上，確實是完全符合產業上發展所需，且所揭露之結構發明亦是具有前所未有的創新構造，所以其具有「新穎性」應無疑慮，又本發明可較之習知結構更具功效之增進，因此亦具有「進步性」，其完全符合我國專利法有關發明專利之申請要件的規定，乃依法提起專利申請，並敬請 鈞局早日審查，並給予肯定。In summary, the overall structural design, practicability and efficiency of the disassembly tool of the present invention are completely in line with the development of the industry, and the disclosed structural invention has an unprecedented innovative structure, so it has "novelty" It should be undoubtedly considered that the present invention can be more effective than the conventional structure, and therefore has "progressiveness", which fully complies with the requirements of the application requirements of the invention patents of the Chinese Patent Law, and is a patent application according to law.
