Description of the invention (1) Detailed description of the invention [Technical field to which the invention belongs] The present invention relates to a perforator for a waterway pipe and the like. [Known technology] In the past, when branch pipes were installed for water pipes, etc., branch pipes with branch plugs with branch plugs were installed on this pipe, and a perforator was fixed to the branch pipe holders. The lower end is perforated. The perforator has various forms. For example, the perforator disclosed in Japanese Patent Utility Model Publication No. Hei 6-45284, is made by connecting a motor and a main shaft (rotating shaft) or The parallel arrangement of components such as the conveying screw reduces the overall height to make it easier to use. [Field of the invention] However, as described above for the mechanism of conveying by a screw 5 When the handle is rotated for one turn, a tool distance of 1 pitch is conveyed 1 In order to move a tool for punching to a punching position In this case, it is not only necessary to rotate the conveying control handle a few times, but also it is not easy to move the tool. In addition, it takes more time to move the tool to move the tool, and the screw conveying mechanism is used for conveying during cutting. The reverse thrust force to the control lever will act on the lead angle of the screw. Since it is not easy to transfer the cutting state to the conveying control lever, the tool is susceptible to the clamping state, and the correspondence in the clamping state is not easy. For this reason, screw conveyors have hardly been used in conventional conveyors such as ball discs. Also 'instead of the above-mentioned conveying mechanism by screw, there are also balls -3-
548151 五、發明說明（2 ) 盤等使用齒條與小齒輪的傳送機構。然而，此種機構爲了 要將齒條相對於小齒輪構成移動動作，將所固定的小齒輪 作爲中心而考慮時，則必須要考慮到齒條的移動量以及收 納的空間，其結果，則會有本體需要更長的長度之問題發 生。 進一步而言，於現代中對水道管的穿孔方法係爲使用支 管架分水栓，於該支管架分水栓上部的螺鎖部，藉使用於 穿孔機本體所安裝有的支管架固定螺釘螺合固定，故有著 以下所述之不方便之處。亦即，將穿孔機本體固定於支管 架分水栓的支管架固定螺帽之螺紋係爲右螺紋，而刀具的 旋轉方向也是爲右轉方向，爲此，在穿孔當中若刀具因切 削抵抗而產生卡緊狀態時，刀具所承受的徑向方向之反作 用力會使螺釘帽鬆脫而朝左向旋轉。此時，爲使電動穿孔 機更加的將扭矩傳達至刀具，於固定的右旋螺絲的鬆脫方 向（左方向）之力開始作用，使得已固定於支管架分水栓 的穿孔機本體之支管架固定螺帽鬆脫，進而造成穿孔機本 體有震動之問題產生。 爲了解決該種問題，於上述之日本專利實用新型公報第 平6-45284號所揭露之穿孔機中，在安裝於旋轉軸之刀具 陷入本管造成卡緊而停止之際，使用離合器而將馬達之軸 與小齒輪之間的連結分離，藉由吸收停止時的衝擊、同時 使馬達繼續維持旋轉’而防止馬達的燒毀損害。然而在此 種設置離合器的情況下，亦會有結構變得更加複雜化、招 5481 各 1 五、發明說明（3) 致重量的增加、成本的增加等新的問題產生。 另，於穿孔機使用的刀具與旋轉軸的裝設部中，會產生 下述不便之處。亦即，使用於穿孔機的刀具方面，右旋螺 絲係形成爲用以固定旋轉軸的型態，爲使刀具能簡單的自 旋轉軸取出，而在刀具側設置有扳手固鎖承接面。 但是，在目前的穿孔機之旋轉軸中，並未設置有爲使刀 具取出之扳手固鎖承接面。於旋轉軸未設置有扳手固鎖承 接面的原因，係謂相當於本穿孔機之最小穿孔能力之支管 架分水栓，具有爲分歧所稱徑爲20的支管架分水栓，該支 管架分水栓的內徑約爲21mm。因此，穿孔機的旋轉軸不可 較支管架分水栓的內徑爲大，且於旋轉軸內徑中爲了要固 定刀具所形成之螺絲，因於旋轉軸的外徑具有扳手固鎖承 接面時，旋轉軸的壁厚會過於呈現薄狀，故不可在旋轉軸 的外徑設置扳手固鎖承接面。另外，在進行穿孔時的狀態 中，爲使水道管在不斷水的狀態下進行穿孔，防止水道水 往本體內部侵入係爲必要，於旋轉軸外徑軸向支撐旋轉軸 的元件（支管架托座）側邊設置密封元件用以進行密封。 爲此，若旋轉軸外徑形成有扳手承接固鎖面的情況之下， 在刀具拉升至上端部爲止的狀態時，前述的密封元件便無 法形成設置於扳手承接固鎖面上。且，於支管架分水栓的 內部，因設有閥體（valve)，在刀具拉升至上端部爲止的 狀態時，刀具前端並不會對閥體有所干涉。倘若在於形成 有干涉狀態之情況下，因閥體無法閉合之故，當穿孔機本 548151 五、發明說明（4 ) 體自支管架分水栓取出時，由於水道管的內壓力而造成水 道水向外噴出，而穿孔機本體亦無法自支管架分水拴取 出。 因爲上述的理由，故於習知的穿孔機中並未設置有用以 將於旋轉軸的刀具取出之扳手固鎖承接面。其結果，因穿 孔時的刀具是朝右旋轉，故於切削時的切削反作用力會因 刀具卡緊而將其力加諸於旋轉方向，進而產生在過負荷以 及刀具遭到卡緊時，無法順利的將刀具自旋轉軸取出之問 體。若考慮上述之事件而在旋轉軸形成扳手固鎖承接面的 情況之下，會造成本體的全長過長，無法使穿孔機本體簡 潔。 又，在目前的穿孔機中將以卡緊的刀具取出之方法，係 爲在刀具的扳手固鎖承接面使用扳手，利用由旋轉軸到馬 達的動力傳動抵抗，對扳手給予瞬間性的衝擊而進行將刀 具取出之動作，然，在此方法之下，則需考慮到由旋轉軸 到馬達的動力傳動元件遭到損害之問題。在給予衝擊所仍 無法將刀具取出的情況之下，因於旋轉軸係爲使用大管鉗 等工具且以利用大管鉗將固定的刀具取出，故會造成於旋 轉軸的外徑產生損害，而使旋轉軸外徑用於密封的元件遭 到損傷，於穿孔時產生水道水進入穿孔機本體之問體。 在此，本發明之主要目的，係改變藉由螺桿之刀具傳送 機構，採用爲使用鏈條、線纜、皮帶等刀具傳送機構，同 時，於穿孔進行中就算是刀具遭到卡緊的情況，提供一種 548151 五、發明說明（5) 具備有防止用以固定穿孔機本體之右旋螺絲朝鬆脫方向（ 左向）旋轉之防止反轉裝置之新型穿孔機，用以解決上述 之問題點。 另，本發明之又一目的，係提供一種刀具在旋轉軸呈現 卡緊狀態時，亦可簡單的將刀具取出之機構。 【解決問題之方式】 爲此，本發明採用之技術性的解決方式係爲， 本發明之穿孔機，其特徵係爲，配置於穿孔機本體之馬 達的旋轉力傳遞至管軸，進一步而言，係爲將旋轉力傳遞 至於管軸內徑所配置之旋轉軸，於可一面將設置於旋轉軸 之刀具朝被加工體移動一面對被加工體進行穿孔的穿孔機

前述支撐部介於其中，而使可移動旋轉軸之穿孔機。 本發明之穿孔機，其特徵係爲，爲防止用以驅動前述鏈 條或線纜等之鏈輪抑或是皮帶輪發生逆轉，而裝置有制動 器之穿孔機。 本發明之穿孔機，其特徵係爲，前述穿孔機固定於前述 548151 五、發明說明（6 ) 支管架分水栓的情況下，川空機與支管架分水栓之間，設 置有防止穿孔機迴轉之防止逆轉裝置之穿孔機。 本發明之穿孔機，其特徵係爲，於設置在穿孔機之旋轉 軸所裝設的刀具、以及與旋轉軸間之扳手固鎖承接面所具 有的環管介於其中，將刀具固定於旋轉軸之穿孔機。 【本發明較佳實施例之詳細說明】 以下，根據圖式進行與本發明有關實施例之說明，第1 圖所示，係本發明實施例之穿孔機安裝於支管架分水栓上 之狀態之側剖面圖，第2圖所示，係穿孔機之重要部位之 側剖面圖，第3圖所示，係穿孔機之重要部位之正剖面 圖，第4圖係爲刀具與旋轉軸之放大圖，其中，第4A圖所

穿孔機係爲，相對於被固定在支管架分水栓7’藉由設置 在穿孔機側的固定螺帽介於連接裝置（attachment)而被右 旋螺釘所固定。 於第2圖中，旋轉軸2的下端’係爲裝設於穿孔機本體 1之變速箱蓋9之下端，藉由六角穴螺絲10而固定’支管 五、發明說明（7 ) 架托座11則藉由滾針軸承12於可自由旋轉的情況下所支 撐’支管架托座11係介於連接裝置，裝設有爲使穿孔機裝 設至支管架分水栓7的支管架固定螺帽8。支管架固定螺 帽8,係於前述支管架托座11可上下活動的狀態下進行組 裝，且與支管架托座11之間的內周面中，則裝設有密封環 1 3以及防塵圈14。 於旋轉軸2的下端係裝設有旋轉軸導引部15,於旋轉 軸導引部15的兩端爲裝設在管軸3 (後述將有構造的詳細 說明）之長溝3a，於旋轉軸導引部15的兩端緊密且無間隙 地組入導引銷16,此外，旋轉軸導引部15亦於旋轉軸2 的上端部以無間隙地進行組裝，且由定位環17所固定。 導引銷16係爲裝設於貫通保持旋轉軸2之銷18之端 部，於管軸3外徑可自由移動之方式組裝的導引銷16，於 已完成組裝的導引銷16之外周緣組裝銷遮蓋部，且將滾珠 軸承20壓入導引銷16之上部及下部。該等物件裝設置係 於相對管軸3在可自由移動下組裝至鏈條支持器21內部， 並以定位環22加以固定。 此外，前述管軸3於內徑部收納有旋轉軸2，長溝3a 相對於中心軸對稱性的設有兩個地方，於該長溝3a內，前 述旋轉軸導引部15及銷以無法進行旋轉，同時，可上下自 由移動的方式組裝。旋轉軸2的下端介於管軸3內之軸套 23間保持自由移動的狀態。 管軸3的上端部藉由滾針軸承24以及止推軸25，以可 五、發明說明（8 ) 自由迴轉的狀態下安裝於本體蓋部la，且管軸3的下端部 藉由滾珠軸承26，以可自由迴轉於安裝至穿孔機本體1之 變速箱蓋9的狀態下裝置。 鏈條支持器21係爲構成鏈條驅動裝置5之鏈條5a的兩 端所固定，鏈條5a係爲於穿孔機本體1內以上下進行配置 之2個鏈輪27、28所捲繞。於第3圖中，配置於上方之鏈 輪27係藉由於鏈輪軸29上之鍵30進行裝配，且鏈輪軸29 係藉由襯套31於與鏈輪27之間的間隙配置齒輪32，且藉 由鍵33的安裝避免齒輪32迴轉。齒輪32係與於穿孔機本 體1內保持可自由環轉之控制軸34所形成的齒輪35嚙 合，控制柄36係安裝於控制軸34。於控制軸34中設置有 〇型環37，彈簧38、平墊圈39、制動器40、制動盤41、 平墊圈42係以控制軸34而組裝置穿孔機本體1內。 於下方所配置的鏈輪28係用以裝置在穿孔機本體1內 的軸套45以可自由旋轉的狀態下安裝於鏈輪軸44。 於第2圖中，管軸3係藉由鍵46將第1傳動裝置47進 行安裝，該第1傳動裝置47使用減速齒輪裝置48組裝於 馬達6的出力軸49,藉由驅動馬達6的旋轉，形成管軸3 在使用減速齒輪裝置48下而可進行旋轉。此外，亦可使用 傳動皮帶等其他種類的減速機構用以替代齒輪。 於第1圖中，支管架分水栓7於水道管50係爲螺釘51 及螺帽52所固定，於該支管架分水栓7係爲穿孔機本體1 於使用支管架固定螺帽8、連接裝置53且以右旋螺釘所固 -10- 五、發明說明（9 ) 定。於穿孔機本體1中則設置有作爲防止逆轉構造的防止 逆轉之傳動皮帶裝置54，防止逆轉之傳動皮帶裝置54之 鉤部55，係用以扣鎖吊環螺母56，該吊環螺母56係爲支 管架分水栓7固定於水道管且利用於螺釘前端所形成的螺 紋加以螺鎖裝配者。於裝設有防止逆轉之傳動皮帶裝置54 之狀態下，係以與穿孔機鬆脫方向逆向作用之張力運作方 式進行裝配。此外，若是爲防止逆轉之傳動皮帶裝置54以 及吊環螺母56等防止穿孔機的旋轉者，亦可使用其他種形 式之裝置。 由上述所構成的穿孔機進行說明。 於水道管50上所之支管架分水栓7係利用支管架固定 螺帽8、連接裝置53以右旋螺紋的方式固定於安裝有旋轉 軸2及安裝於該旋轉軸2之刀具4的穿孔機本體1，防止 逆轉之傳動皮帶裝置54管架分水栓7之吊環螺母於緊繃狀 態下進行固鎖。 驅動馬達6經由鍵速齒輪裝置48使第1傳動裝置47旋 轉，進一步而言係使管軸3進行旋轉。藉由管軸3的旋 轉，相對於管軸3所安裝之不可相對旋轉之旋轉軸2亦會 旋轉，而安裝於旋轉軸2前端之刀具同時亦會旋轉。在此 狀態下旋轉控制柄36，旋轉於控制軸34所形成的傳動機 構35,與該傳動機構35嚙合的傳動機構32進行旋轉時將 帶動鏈輪軸29旋轉。藉由鏈輪軸29的旋轉而使鏈輪旋 轉，藉此移動鏈輪27、28所捲繞之鏈條5a。藉由鏈條5a -11- 五、發明說明（10 ) 的移動，裝配有鏈條5a之鏈條支持器21便會朝下方移 動，該鏈條支持器21係沿著進行迴轉之管軸的外徑朝下方 移動。此時，裝設於鏈條支持器21之銷係因亦爲在管軸3 形成之長溝3a內一面移動一面移動，故爲銷所貫通之旋轉 軸2亦會朝下方移動，且可藉由裝設於旋轉軸2下方之刀 具4進行於水道管50之穿孔動作。穿孔時，因鏈條5a連 結於鏈條支持器21，故鏈條支持器21內部的滾珠軸承20 及導引銷16會朝刀具4傳送方向施加推進力。因銷18裝 配於導引銷16及旋轉軸2之故，旋轉軸2將藉由銷18朝 刀具4的傳送方向施加推進力。銷18則導引管軸3的長溝 3a，將旋轉軸2往刀具4傳送方向移動。 藉由上述傳送刀具4,當刀具4的刀刃先端到達水道管 50之內徑時，於水道管50的內徑中因有水壓加注之故， 故會形成水道水會自水道管噴出的狀態。噴出的水道水雖 會由支管架分水栓7所分支的分歧孔中流出，於支管架分 水栓7的內部仍存在有些許殘壓，而旋轉軸2的斷面便形 成殘壓的受壓面，力量便朝旋轉軸2的反推方向運動。將 旋轉軸2反推之後，因造成控制軸34的逆轉，故藉由固定 於穿孔機本體1以及控制軸34之制動盤4 1與制動器40的 摩擦，利用控制軸34受到制動器的作用，就算於旋轉軸2 的斷面仍有殘壓增加，不僅不會發生穿孔用的刀具4被推 回的狀況，且控制軸34亦不會逆轉。 此外，於穿孔機本體亦安裝有防止逆轉之皮帶傳動裝置 -12- 548151 五、發明說明（11) 54，藉由防止逆轉之皮帶傳動裝置54之鉤部55以扣鎖吊 環螺母56，該吊環螺母56係爲支管架分水栓7固定於水 道管且利用於螺釘前端所形成的螺紋加以螺鎖裝配者。 另，在裝設有防止逆轉之皮帶傳動裝置54的狀態中’因張 力的動作係與穿孔機的鬆脫方向逆向作用之故，固定的右 旋螺絲朝鬆脫方向（左向）之力作用時，藉由防止逆轉之 皮帶傳動裝置54的作用而可解決穿孔機本體1震動的問 題。 其次，爲解決穿孔機所使用的刀具4以及旋轉軸2的裝 設部位的問題點，該設備請參照第第4圖進行說明。 穿孔機所使用的刀具4如第4B圖所示，係爲以右旋螺 絲固定於旋轉軸2，於刀具側則設置有用以鬆脫之用的扳 手固鎖承接面4a，於旋轉軸2則未形成有扳手固鎖承接 面。爲此，當旋轉軸2與刀具4形成卡緊狀態時，並無法 簡單的自旋轉軸2取出刀具4。 在此，本發明係使用具有扳手固鎖承接面之環管57用 以解決上述問題。於第4A圖中，旋轉軸2組裝至穿孔機本 體1內，進行旋轉以及上下移動。具有扳手固鎖承接面之 環管57在於刀具裝設之際便進入刀具4與旋轉軸2之間， 將刀具4藉由於旋轉軸2螺鎖而固定。藉由此種方式，於 水道管穿孔時藉由作用於刀具4之刀刃先端的切削負荷， 而作用將旋轉軸2與刀具4完全固鎖之力。然，環管57會 因爲於旋轉軸2的摩擦力而完全的被固定，故除可將環管 -13- 548151 五、發明說明（12) 57與旋轉軸2作爲一體考慮外，於旋轉軸2亦可假設爲可 設置類似的扳手固鎖承接面。結果，於卸下刀具4時，僅 需於環管57與刀具4的扳手固鎖承接面以扳手等工具扣 合’在扳手扣合住扳手固鎖承接面的瞬間加諸力量，便可 簡單的將刀具自旋轉軸2卸下。如此，使用具有扳手固鎖 承接面之環管57用以將刀具4取出，刀具4卸下時的力量 (衝擊力）不會加諸於自旋轉軸2到馬達6爲止的動力傳 達元件，且可防止動力傳達元件的損傷。 以上，雖係就有關本發明之實施例進行說明，但於上述 各個實施例中，管軸3、旋轉軸2、旋轉軸2與穿孔機本體 1的組裝狀態、馬達6與管軸3之間的動力傳送機構等 等，並不限定爲上述之實施態樣，亦可採用其他種類的實 施態樣。刺外，有關刀具傳送機構，亦可使用皮帶、線纜 等驅動機構來替代鏈條傳動機構。 進一步而言，在不脫離本發明之精神亦或主要特徵下可 進行各種各樣形式之實施態樣，爲此，在前述所有實施例 僅單就舉例而設，不可作爲限定之解釋。 【發明效果】 如同上述詳細說明，本發明係藉由於穿孔機中之刀具的 傳送機構，由螺桿機構轉而採用鏈條、皮帶、線纜等刀具 傳送機構，相較於螺桿傳送機構之下可得到較大之傳送 量。爲此，無須多次的旋轉傳送控制柄，便可簡單的使刀 具進行移動，亦可減少使刀具移動的時間。亦即，相較藉 -14- 548151 五、發明說明（13) 由齒條以及小齒輪的傳送機構下，可使穿孔機達到整體的 小型化。且，藉由設置有防止反轉之傳動皮帶，於穿孔時 可解決穿孔機本體的震動問題。又，藉由使用旋轉軸與刀 具之間設有扳手固鎖承接面的環管，於旋轉軸可設置類似 的扳手固鎖承接面，就算是過負荷以及刀刃先端卡緊時， 亦可簡單的將刀具自旋轉軸取出。爲此，刀具卸下時的力 量（衝擊力）不會加諸於自旋轉軸到馬達爲止的動力傳達 元件，故不會產生損傷。且因大管鉗沒有固定旋轉軸之必 要，故無水道水進入穿孔機本體內部之問題，具有種種優 秀的效果。 圖式簡單說明 第1圖所示係本發明實施例之穿孔機安裝於支管架分水 栓上之狀態之側剖面圖。

Description of the invention (2) Transmission mechanisms such as disks using racks and pinions. However, in order for such a mechanism to move the rack with respect to the pinion and the fixed pinion as the center, it is necessary to consider the amount of rack movement and the storage space. As a result, There is a problem that the body needs a longer length. Further, in modern times, the method of perforating the water pipe is to use a branch pipe branch water plug, and a screw lock part on the branch pipe branch water plug is used to fix the screw of the branch pipe bracket installed on the perforator body. Because it is fixed, it has the following inconveniences. That is, the thread of the pipe rack fixing nut that fixes the perforator body to the pipe rack diverter is the right thread, and the direction of rotation of the tool is also the right direction. For this reason, if the tool is cutting due to cutting resistance during perforation, When the clamping state occurs, the reaction force in the radial direction received by the tool will loosen the screw cap and rotate to the left. At this time, in order to further transmit the torque to the cutter by the electric perforator, the force in the loosening direction (left direction) of the fixed right-handed screw starts to act, so that the branch pipe of the perforator body that has been fixed to the branch pipe branch water tap The fixed nut of the rack is loosened, which causes the vibration of the puncher body. In order to solve this kind of problem, in the punching machine disclosed in the aforementioned Japanese Patent Utility Model Publication No. Hei 6-45284, when a cutter mounted on a rotating shaft is caught in the pipe and caused to stop and stop, a clutch is used to stop the motor. The connection between the shaft and the pinion is separated, and the motor is kept rotating while absorbing shocks at the time of stopping, thereby preventing damage to the motor. However, in such a case of setting a clutch, there are also new problems such as the structure becoming more complicated, 5481 each. 5. Description of the Invention (3) Increase in weight and cost. In addition, the following inconveniences are caused in the installation part of the cutter and the rotary shaft used in the puncher. That is, in the tool used for the punching machine, the right-handed screw system is formed to fix the rotating shaft. In order to make the tool easy to take out from the rotating shaft, a wrench lock receiving surface is provided on the tool side. However, the rotating shaft of the current punching machine is not provided with a wrench lock receiving surface for removing the tool. The reason why the rotating shaft is not provided with a wrench to lock the receiving surface is that the branch pipe bracket is equivalent to the minimum perforating capacity of the puncher. It has a branch pipe bracket with a diameter of 20 which is different from the branch pipe. The branch pipe bracket The inner diameter of the water trap is about 21mm. Therefore, the rotary shaft of the perforator must not be larger than the inner diameter of the branch pipe water trap, and the screw formed to fix the tool in the inner diameter of the rotary shaft, because the outer diameter of the rotary shaft has a wrench lock receiving surface. The wall thickness of the rotating shaft will be too thin, so it is not possible to set a wrench lock receiving surface on the outer diameter of the rotating shaft. In addition, in the state of perforation, in order to perforate the water pipe in a state of continuous water, it is necessary to prevent the intrusion of water from the inside of the body. It is an element (branch support) that axially supports the rotation shaft on the outer diameter of the rotation shaft A sealing element is provided on the side of the bracket for sealing. Therefore, if a wrench receiving locking surface is formed on the outer diameter of the rotary shaft, the aforementioned sealing element cannot be formed on the wrench receiving locking surface when the tool is pulled up to the upper end portion. In addition, since a valve body is provided inside the branch pipe tap, the front end of the tool does not interfere with the valve body when the tool is pulled up to the upper end. If the interference state is formed, because the valve body cannot be closed, when the puncher 548151 V. Invention Description (4) When the body is taken out from the branch pipe branch water tap, the water channel water is caused by the internal pressure of the water channel pipe. It is sprayed outwards, and the body of the perforator cannot be taken out from the branch pipe. For the reasons described above, the conventional punching machine is not provided with a wrench to lock the receiving surface to take out the cutter of the rotary shaft. As a result, since the tool rotates to the right during piercing, the cutting reaction force during cutting will apply its force to the direction of rotation due to the clamping of the tool, which may result in an overload and a tool being clamped. Remove the tool from the rotating shaft smoothly. If the above event is considered and the wrench lock receiving surface is formed on the rotating shaft, the total length of the body will be too long, and the body of the puncher will not be simple and clean. Moreover, in the current punching machine, the method of taking out the clamped tool is to use a wrench on the wrench lock receiving surface of the tool, and use the power transmission resistance from the rotating shaft to the motor to give an instant impact to the wrench. The action of removing the cutter is performed. However, under this method, the problem of damage to the power transmission element from the rotating shaft to the motor needs to be considered. In the case where the tool cannot be taken out due to the impact, because the rotary shaft system uses tools such as large pipe wrenches and the fixed tools are taken out with large pipe wrenches, it will cause damage to the outer diameter of the rotary shaft. The components of the outer diameter of the rotating shaft used for sealing are damaged, and water channels enter the body of the punching machine during perforation. Here, the main object of the present invention is to change the tool conveying mechanism by a screw to adopt a tool conveying mechanism such as a chain, a cable, a belt, etc. At the same time, even if the tool is clamped during the perforation, it provides A 548151 V.

In the first figure, the branch pipe bracket 7 is fixed to the water pipe 50 by screws 51 and nuts 52, and the branch pipe bracket 7 is a puncher body 1. The branch pipe bracket is used to fix the nut 8, The connecting device 53 is fixed by a right-handed screw. -10- V. Description of the invention (9). The perforating machine body 1 is provided with a reversing preventing transmission belt device 54 as a reversing preventing structure, and a hook portion 55 of the reversing preventing transmission belt device 54 is used to lock a ring nut 56 which is a branch pipe. The frame water diverter 7 is fixed to the water pipe and is screwed together by a screw formed at the front end of the screw. In the state equipped with a transmission belt device 54 for preventing reversal, the assembly is performed in a tension operation mode which acts in the reverse direction with the release direction of the puncher. In addition, if the transmission belt device 54 and the ring nut 56 are used to prevent the rotation of the puncher to prevent reversal, other types of devices may be used. The above-mentioned punching machine will be described. The branch pipe bracket 7 on the water pipe 50 is fixed to the perforation of the rotary shaft 2 and the cutter 4 mounted on the rotary shaft 2 by means of a right-handed screw with a branch pipe fixing nut 8 and a connecting device 53. The machine body 1 prevents the reverse rotation of the transmission belt device 54 and the ring nut of the pipe rack water hydrant 7 to be locked in a tight state. The drive motor 6 rotates the first transmission device 47 via the key-speed gear device 48, and further rotates the tube shaft 3. With the rotation of the pipe shaft 3, the non-rotatable rotary shaft 2 installed with respect to the pipe shaft 3 also rotates, and the tool installed at the front end of the rotary shaft 2 also rotates. In this state, when the control handle 36 is rotated, the transmission mechanism 35 formed on the control shaft 34 is rotated, and when the transmission mechanism 32 engaged with the transmission mechanism 35 is rotated, the sprocket shaft 29 is rotated. The sprocket is rotated by the rotation of the sprocket shaft 29, whereby the chain 5a wound by the sprocket 27, 28 is moved. With the movement of the chain 5a -11- 5. Description of the invention (10), the chain support 21 equipped with the chain 5a will move downward, and the chain support 21 will be directed downward along the outer diameter of the rotating pipe shaft mobile. At this time, the pin installed on the chain holder 21 is also moved side by side in the long groove 3a formed by the pipe shaft 3. Therefore, the rotation shaft 2 penetrated by the pin will also move downward, and can be installed by A cutter 4 provided below the rotary shaft 2 performs a perforation operation on the water pipe 50. At the time of perforation, the chain 5a is connected to the chain holder 21, so the ball bearing 20 and the guide pin 16 inside the chain holder 21 apply a pushing force in the direction of the conveyance of the cutter 4. Since the pin 18 is fitted to the guide pin 16 and the rotating shaft 2, the rotating shaft 2 will apply a propulsive force to the conveying direction of the cutter 4 through the pin 18. The pin 18 guides the long groove 3a of the pipe shaft 3, and moves the rotary shaft 2 in the conveying direction of the cutter 4. With the above-mentioned conveying cutter 4, when the cutting edge of the cutter 4 reaches the inner diameter of the water pipe 50, water pressure is added to the inner diameter of the water pipe 50, so water can be discharged from the water pipe. status. Although the spouted channel water will flow out from the branch hole branched by the branch pipe branch water tap 7, there is still some residual pressure inside the branch pipe branch water tap 7, and the section of the rotating shaft 2 forms a residual pressure. By pressing the surface, the force moves in the reverse direction of the rotation shaft 2. After the rotary shaft 2 is pushed backward, the control shaft 34 is reversed. Therefore, the friction between the brake disk 41 and the brake 40 fixed to the punch body 1 and the control shaft 34 and the brake 40 is used to control the shaft 34 to receive the brake. There is still an increase in the residual pressure on the cross-section of the rotary shaft 2. Not only does the punching tool 4 not be pushed back, but the control shaft 34 is not reversed. In addition, the perforator body is also equipped with a belt transmission device to prevent reverse rotation-12- 548151 V. Description of the invention (11) 54 The hook 55 of the belt transmission device 54 to prevent reverse rotation is used to lock the ring nut 56 The nut 56 is an assembler who fixes the branch pipe branch water plug 7 to the water pipe and uses a thread formed at the front end of the screw to screw the assembly. In addition, in the state where the belt transmission device 54 for preventing reversal is installed, 'due to the action of tension acting in the reverse direction with the release direction of the punch, the fixed right-handed screw acts in the release direction (left direction). At this time, the problem of vibration of the puncher body 1 can be solved by the action of the belt transmission device 54 that prevents reverse rotation. Next, in order to solve the problem of the installation parts of the cutter 4 and the rotary shaft 2 used in the punching machine, please refer to FIG. 4 to explain the equipment. As shown in FIG. 4B, the cutter 4 used in the punching machine is fixed to the rotation shaft 2 with a right-hand screw, and a receiving wrench 4a is provided on the cutter side to lock the receiving surface 4a. No wrench lock receiving surface is formed. For this reason, when the rotary shaft 2 and the tool 4 are in a locked state, it is not easy to take out the tool 4 from the rotary shaft 2. Here, the present invention uses a ring pipe 57 having a wrench to lock the receiving surface to solve the above problems. In Fig. 4A, the rotary shaft 2 is assembled into the puncher body 1 and is rotated and moved up and down. The ring pipe 57 having a wrench lock receiving surface enters between the tool 4 and the rotary shaft 2 when the tool is installed, and the tool 4 is fixed by screwing the rotary shaft 2. In this way, during the perforation of the water pipe, a force that fully locks the rotary shaft 2 and the tool 4 is exerted by the cutting load acting on the tip of the cutting edge of the tool 4. Of course, the ring pipe 57 will be completely fixed due to the frictional force on the rotating shaft 2. Therefore, in addition to considering the ring pipe-13-548151 V. Invention Description (12) 57 and the rotating shaft 2 as a whole, 2 It can also be assumed that a similar wrench lock receiving surface can be provided. As a result, when the cutter 4 is removed, it is only necessary to use a tool such as a wrench to fasten the wrench fixing lock receiving surface of the ring pipe 57 and the cutter 4 to apply force at the moment when the wrench engages the wrench fixing locking receiving surface, and it is simple Remove the tool from the rotating shaft 2. In this way, a ring pipe 57 having a wrench to lock the receiving surface is used to take out the cutter 4, and the force (impact force) when the cutter 4 is removed will not be applied to the power transmission element from the rotation shaft 2 to the motor 6, and Prevents damage to power transmission elements. Although the embodiments of the present invention have been described above, in each of the above embodiments, the assembly state of the tube shaft 3, the rotation shaft 2, the rotation shaft 2 and the puncher body 1, and between the motor 6 and the tube shaft 3. The power transmission mechanism and the like are not limited to the above-mentioned implementation modes, and other types of implementation modes can also be adopted. In addition to thorns, drive mechanisms such as belts and cables can also be used in place of the chain drive mechanism for the tool transfer mechanism. Furthermore, various forms of implementation can be made without departing from the spirit or main features of the present invention. For this reason, all the foregoing embodiments are provided by way of example only, and should not be interpreted as a limitation. [Effects of the Invention] As described above in detail, the present invention uses the tool conveying mechanism of the punching machine to switch from the screw mechanism to the chain, belt, cable and other tool conveying mechanisms. Compared with the screw conveying mechanism, it can be obtained. Larger throughput. For this reason, the tool can be simply moved without rotating the transfer control lever multiple times, and the time required to move the tool can be reduced. That is, compared with -14-548151 V. Description of the invention (13) The transmission mechanism of the rack and pinion can make the punching machine overall smaller. Moreover, by providing a transmission belt for preventing reversal, the vibration problem of the puncher body can be solved during punching. In addition, by using a ring pipe with a wrench lock receiving surface between the rotary shaft and the cutter, a similar wrench lock receiving surface can be provided on the rotary shaft, which can be easily used even when overloaded and the cutting edge is clamped. Remove the tool from the rotary axis. Therefore, the force (impact force) when the tool is removed is not applied to the power transmission element from the rotary shaft to the motor, so no damage is caused. And because the large pipe wrench does not have the necessity of fixing the rotating shaft, the problem that no water can enter the inside of the body of the punching machine has various excellent effects.
