Description
本發明係涉及一種拔卸裝置;特別是指一種快速開合式之創新拔卸裝置結構型態揭示者。The invention relates to a lifting device; in particular to a quick opening and closing type of structural uncovering device.
本發明所指拔卸裝置,通常廣泛作為拆卸軸承、惰輪、皮帶輪等與軸桿緊配合定位的組件之功用。The lifting and unloading device of the present invention is generally widely used as a component for disassembling a bearing, an idler pulley, a pulley, and the like, which are closely matched with the shaft.
就目前習知可見的典型拔卸裝置結構型態而言,可調閱中華民國專利證書號M373804之「簡便式拔輪器結構」新型專利所揭,其主要架構係包括支持座、中心螺桿組、控制盤、臂爪以及調整帽,其中該中心螺桿組係螺組於支持座,臂爪係為兩組成對狀態樞組於支持座二側,調整帽連同控制盤組設於支持座上方間隔處,調整帽螺組於支持座所設一中心管的外螺紋部位呈可順逆向轉動,以帶動控制盤升降,二臂爪的上端連設在控制盤二側所設導滑槽中。As for the typical type of loading and unloading device that can be seen at present, it can be read by the new patent of the "Simple Puller Structure" of the Republic of China Patent No. M373804. Its main structure includes the support base and the center screw set. The control screw, the arm claw and the adjusting cap, wherein the center screw set is a screw set on the support base, the arm claws are two pairs of state pivots on the support side, and the adjustment cap is arranged on the support seat. Wherein, the adjusting cap screw group is rotatably reversely rotated in the external thread portion of a central tube provided in the support seat to drive the control panel to be lifted and lowered, and the upper ends of the two arm claws are connected in the guiding chutes disposed on the two sides of the control panel.
前段所述習知拔卸裝置型態,其使用時必須透過轉動該調整帽以帶動控制盤升降,藉此改變二臂爪上端高度位置,從而改變調整二臂爪的相對開合幅度(亦即夾放狀態)。In the prior art, the conventional lifting device type must be used to rotate the adjusting cap to drive the control panel to move up and down, thereby changing the height position of the upper end of the two arm claws, thereby changing the relative opening and closing range of the adjusting two arm claws (ie, Clipping state).
惟查,前述習知拔卸裝置結構於實際應用經驗中發現仍舊存在一些問題與缺弊,舉例而言,至少存在構件過多以及調整緩慢欠缺效率等問題點,其中就構件過多的部份而言,由於其控制盤上必須再螺組一調整帽,而支持座的中心管須增設外螺紋部位以供該調整帽螺組,且控制盤與調整帽之間亦須再透過扣件的組配以達成連動狀態,因此造成其構件頗多而令製造加工及組立等各方面成本均大幅提高之問題點;再就調整緩慢欠缺效率的部份而言,因為前述習知拔卸裝置,其二臂爪相對開合幅度的調整,是透過該調整帽的順逆向轉動螺旋升降來達成,所以使用者無論是要將該二臂爪往打開方向調動或者往閉合方向調動,均無法快速達成,必須經過緩慢的位移過程方可達成,如此而直接影響到其拆卸作業的效率與工作進度。However, the above-mentioned conventional unloading device structure has found that there are still some problems and shortcomings in the practical application experience. For example, at least there are problems such as too many components and slow adjustment efficiency, among which the excessive parts are As the control panel has to be screwed together with an adjustment cap, the central tube of the support has to be externally threaded for the adjustment of the cap screw set, and the control disc and the adjustment cap must be further assembled through the fastener. In order to achieve a linkage state, the number of components is quite large, and the cost of manufacturing, processing and assembly is greatly increased. In the part of adjusting the slow lack of efficiency, because of the aforementioned conventional unloading device, the second The adjustment of the relative opening and closing width of the arm is achieved by the reverse rotation of the adjusting cap, so that the user cannot move the arm in the opening direction or move in the closing direction. After a slow displacement process can be achieved, which directly affects the efficiency and progress of the disassembly work.
是以,針對上述習知拔卸裝置技術所存在之問題點,如何研發出一種能夠更具理想實用性之創新構造,實有待相關業界再加以思索突破之目標及方向者。Therefore, in view of the problems existing in the above-mentioned conventional loading and unloading device technology, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goals and directions of breakthrough.

The manner (as indicated by the arrow L1) can quickly control the opening extent of the hooking end 52 of the two jaws 50 (as indicated by the arrow L2), when the hooking ends 52 of the two jaws 50 are opened. In the state, the driven end 51 of the two jaws 50 will be displaced toward the oblique upper end of the inclined surface in the inclined surface limiting guide 23 provided in the disk portion 21 of the limiting guide seat 20, and the state will be the limit guiding seat. 20 is pressed downward, and the elastic elastic support member 30 accumulates the elastic force. Therefore, when the user releases the pressure of the second quick opening and closing pressure control portion 60, if the hooking ends 52 of the two clamping jaws 50 are not clamped between For the object, the hooking end 52 of the second jaw 50 will quickly return to the closed state shown in FIG. 3; thereby the jaw 50 can be quickly opened and closed, please refer to FIG. 5 for the user. When the loading and unloading operation of a bearing 70 is performed by the quick opening and unloading device A of the present invention, the user can pass through the two quick opening and closing pressure control portions 60. Pressing action, the hooking end 52 of the two jaws 50 is quickly opened to be hooked on opposite sides of the bearing 70, and then the abutting end 42 of the abutting screw 40 can be abutted against the center of the bearing 70. An end face of a shaft 71 is provided, and then the steering frame 41 is pressed to urge the abutting end 42 of the screw 40 to force the bearing 71 to disengage the bearing 70 from the shaft 71 to achieve the function of the unloading bearing 70.
本發明之優點說明: 本發明所揭「快速開合式拔卸裝置」主要藉由所述支架、限位導動座、彈性頂撐件、抵迫螺桿、夾爪以及快速開合壓控部等所構成之創新獨特結構型態與技術特徵,使本發明對照[先前技術]所提習知結構而言,由於本發明係採用手動壓控方式控制夾爪開合狀態,故結構上可省略前述習知所用的調整帽構件及與其相螺合之螺紋構造,且本發明操作上其夾爪可瞬間快速開合,此部份亦較習知螺轉調整型態快速許多,讓拔卸工作更有效率,此外,因為該二夾爪的受動端係置於限位導動座的盤部所設斜面限位導槽中,此型態令二夾爪在其旋支部之外更增加了一個端部限位點,這使得二夾爪的作動狀態更加穩固(註:因其一端部也獲得限位),大幅降低其受力時偏移變形之機率;故本發明所揭快速開合式拔卸裝置確實能夠讓拔卸裝置達到構件簡化、開合快速且兼具夾爪作動穩固性等諸多實用進步性。Advantages of the present invention: The "quick opening and closing type unloading device" disclosed in the present invention mainly comprises the bracket, the limit guide seat, the elastic top support member, the abutting screw, the clamping jaw, and the quick opening and closing pressure control portion. The innovative unique structure and technical features of the present invention make the present invention control the structure of the prior art according to the prior art. Since the present invention uses the manual pressure control method to control the jaw opening and closing state, the foregoing structure may be omitted. The adjusting cap member used in the prior art and the threaded structure which is screwed therewith, and the jaws of the present invention can be opened and closed quickly in an instant, and this part is also much faster than the conventional screw-turning adjustment type, so that the pulling work is more convenient. Efficiently, in addition, because the driven end of the two jaws is placed in the inclined surface guide groove of the disc portion of the limiting guide seat, this type adds one more to the two jaws outside the rotary branch portion. The end limit point, which makes the action state of the two jaws more stable (note: because one end portion also obtains the limit position), the probability of offset deformation when the force is greatly reduced; therefore, the quick opening and closing type of the invention is disclosed The unloading device can indeed make the lifting device reach the structure Simplified, rapid opening and closing of the jaws and actuating both stability and many other useful advance.
