Description
本發明係一種拉拔器結構，特別係指一種將物件由精密配置之軸桿拆卸而下之拉拔器結構，且該拉拔器具有拆卸動作前之拉勾定位結構，以利工程人員便利、快速操作本發明拉拔器。 The invention relates to a puller structure, in particular to a puller structure for removing an object from a precisely arranged shaft, and the puller has a pull hook positioning structure before the disassembly operation, so as to facilitate engineering personnel. Quickly operate the puller of the present invention.
按，傳動輪(齒輪、皮帶輪)與軸之間由於傳動上之安全性必須以緊密結合方式設置以供軸所傳動之扭力穩定地傳輸至輪上，而當軸若有損壞必須維修或更換時，則需將輪與軸分離，而因為輪與軸係由精確且緊密的配合設置，所以在分離輪與軸的方面，必須使用特定的機具來進行拆卸動作，因此相關產業即設計有拉拔器來針對此種結構，進行拆卸、維修之作業輔助。 Press, the transmission wheel (gear, pulley) and the shaft must be arranged in a tightly coupled manner due to the safety of the transmission, so that the torque transmitted by the shaft can be stably transmitted to the wheel, and if the shaft is damaged, it must be repaired or replaced. , the wheel and the shaft need to be separated, and because the wheel and the shaft system are arranged with precise and close cooperation, in the aspect of separating the wheel and the shaft, a specific machine must be used for the disassembly operation, so the related industry is designed to draw. For the purpose of this structure, the disassembly and maintenance work is assisted.
習用之拉拔器，其係具有一操作部位，並遠離該操作部位設置有數個長爪，該操作部位延伸有一頂撐桿，該各長爪係得調整為開張或夾持，且該操作部位係可調整頂撐桿頂撐。 The conventional drawing device has an operating portion, and is provided with a plurality of long claws away from the operating portion, the operating portion extending a top strut, the long claws being adjusted to open or clamp, and the operating portion The top struts can be adjusted.
而在操作時，使用者先調整操作部位使頂撐桿向軸抵頂，爾後必須一方面旋轉調整螺帽以調整各長爪與該傳動輪之夾抵位置，另一方面又得繼續觀察各長爪是否確切夾抵輪之外側緣，此種操作方式不但工作效率低，且一旦分心於調整操作部位時，亦可能使得各長爪與該傳動輪之夾抵位置錯開而造成夾持不確實，並對傳動輪及產生損傷。 In operation, the user first adjusts the operating position so that the top strut is abutted against the shaft, and then the adjusting nut must be rotated to adjust the clamping position of each long claw and the driving wheel, and on the other hand, continue to observe each Whether the long claws are exactly clamped to the outer edge of the wheel, this operation mode not only has low work efficiency, but once distracted from the adjustment operation portion, the clamping position of each long claw and the transmission wheel may be staggered to cause clamping. Indeed, and damage to the drive wheel.
有鑑於此，本發明人乃針對前述習用創作問題深入探討，並藉由多年從事相關產業之研發與製造經驗，積極尋求解決之道，經過長期努力之研究與發展，終於成功的開發出本發明『拉拔器結構』，以改善習用創作之問題。 In view of this, the present inventors have intensively discussed the above-mentioned conventional creation problems, and actively pursued solutions through years of experience in research and development and manufacturing of related industries. After long-term efforts in research and development, the present invention has finally succeeded in developing the present invention. "Puller structure" to improve the problem of custom creation.

For quick operation of the present drawing puller, please refer to the first to seventh figures, the "drawing device structure" of the present invention includes a base plate 1, an adjusting plate 2, a screw set 3 and a plurality of The bottom of the base plate 1 is formed with a screw hole 11 through which the screw set 3 is disposed. The upper and lower half of the screw hole 11 are each a wide thread segment 111 and a narrow thread segment 112. A plurality of pivoting portions 12 for arranging the movable hooks 4 are formed on the periphery of the base plate 1; the screw set 3 includes an inner screw 31, an outer screw 32 and a screw sleeve 33, and the inner screw 31 is penetrated The type screw is disposed on the narrow thread segment 112 of the screw hole 11. The outer screw 32 is sleeved in the hollow shape on the outer edge of the inner screw 31, and the bottom end of the outer screw 32 is screwed to the wide thread segment of the screw hole 11. 111, the spiral ring sleeve 33 is screwed on the outer edge of the outer screw 32; the adjusting disk 2 is sleeved on the outer screw 32 and interposed between the spiral ring sleeve 33 Between the base plate 1, the tone The whole plate 2 and the base plate 1 are provided with a spring body 5 which is normally elastically supported by the two, and a plurality of pivoting rods 21 are formed on the periphery of the adjusting plate 2, and the upper ends of the plurality of pulling hooks 4 are respectively formed with a pair The inclined guiding surface 41 is disposed on the pivoting rod 21; thus, the rotating sleeve sleeve 33 is rotated to push the adjusting spring 2 to compress the spring body 5 to one side of the base disc 1 , and the pivoting rod 21 is along the inclined guiding surface 41 Sliding, and the push-pull hook 4 pivots relative to the base plate 1, so that the plurality of pull-tabs 4 assume an open state (as shown in the fifth figure); when the pull-ups 4 are located on the object to be removed, only The spiral sleeve 33 needs to be reversely rotated to release the distance between the adjusting plate 2 and the base plate 1. The spring body 5 is pushed against the adjusting plate 2 to gradually separate the base plate 1. The inclined guiding surface 41 is also gradually lost. The guiding effect of the connecting rod 21 causes the pulling hook 4 to be naturally contracted by the center of gravity, and the preliminary positioning can be completed after the hook 4 is hooked on the periphery of the object to be removed (as shown in the sixth figure), and the inner screw 31 is continuously rotated. The object to be removed can be pulled and separated to complete the disassembly operation (as shown in Figure 7).
進一步而言，該基座盤1朝調整盤2一方係設有一導引柱13，該調整盤2係具有一與導引柱13穿套配置之導向孔22；如此，當轉動螺套33以改變調整盤2與基座盤1之間距時，該導向孔22與導引柱13係得配對使調整盤2與基座盤1呈現穩定之垂直運動。 Further, the susceptor disc 1 is provided with a guiding post 13 on one side of the adjusting disc 2, and the adjusting disc 2 has a guiding hole 22 disposed with the guiding post 13 through the sleeve; thus, when the screw sleeve 33 is rotated When the distance between the adjustment disc 2 and the base disc 1 is changed, the guide hole 22 is paired with the guide post 13 so that the adjustment disc 2 and the base disc 1 exhibit a stable vertical movement.
進一步而言，該樞結部12係為一供拉勾4穿設之凹槽121，且該樞結部12與凹槽121兩側係各形成有一掛置口122，該拉勾4係設置有一樞設於掛置口122之軸桿42；如此，以利拉勾4方便於拆卸、配置於不同樞結部12，如第一圖及第二圖所示，分別係本創作以三爪拉勾4及雙爪拉勾4應用實施例上之切換。 Further, the pivoting portion 12 is a groove 121 through which the pull hook 4 is disposed, and the pivoting portion 12 and the groove 121 are respectively formed with a hanging port 122 on both sides thereof. There is a shaft 42 pivotally disposed on the hanging port 122; thus, the Elliott hook 4 is conveniently disassembled and disposed on the different pivoting portions 12, as shown in the first figure and the second figure, respectively The toggle hook 4 and the double-jaw pull hook 4 are switched on the application embodiment.
