Abstract
Description
本發明係關於拆卸器,特別是有關於一種液壓式球接頭拆卸器。This invention relates to a detacher, and more particularly to a hydraulic ball joint detacher.
一般轉接頭係採用緊配合的裝配方式,如汽車傳動軸上的球接頭。因此,當磨損或損壞需要維修或更換時,傳統的拆卸方式係將一端鎖緊的螺帽鬆脫後,對轉接頭與連接桿件樞設組裝處,利用榔頭進行敲打,使轉接頭可與該連接桿件鬆脫開來達到拆卸的目的,而此方式若係敲擊點錯誤,極易傷害或破壞整體組件的完整性。因此,如TW I233868、TW M425029等所揭露之拆卸器,即係針對此問題而專門設計用來拆卸轉接頭,此類習知拆卸器係利用座體先與轉接頭結合定位後,使用帶有螺紋段的推桿與座體螺接在一起,藉由不斷向下旋轉來將轉接頭由連接桿中抵迫出去。In general, the adapters are assembled in a tight fit, such as a ball joint on an automotive drive shaft. Therefore, when the wear or damage needs to be repaired or replaced, the conventional disassembly method is to loosen the nut that is locked at one end, and then pivot the assembly part of the adapter and the connecting rod member, and tap the tap to make the adapter It can be loosened with the connecting rod to achieve the purpose of disassembly, and this method is very easy to damage or damage the integrity of the overall assembly if the hitting point is wrong. Therefore, the detacher disclosed in TW I233868, TW M425029, etc., is specifically designed to disassemble the adapter for this problem. Such a conventional detacher uses the seat body to be combined with the adapter and then used. The push rod with the threaded section is screwed together with the seat body, and the adapter is forced out of the connecting rod by continuously rotating downward.
然而,此方式係使用者施力來驅動推桿前進,而轉接頭與連接桿件之間的結構配合係非常堅固,因此在轉動推桿時十分費力,皆需藉由氣動或電動轉動工具驅動才可順利轉動推桿將該轉接頭拆卸,如果手邊無此類轉動工具時,將會使得拆卸過程非常耗力以及耗時,存在亟待改善之缺弊。However, this method is a force applied by the user to drive the push rod forward, and the structural cooperation between the adapter and the connecting rod is very strong, so it is very laborious to rotate the push rod, and the pneumatic or electric rotating tool is required. The driver can smoothly rotate the push rod to disassemble the adapter. If there is no such turning tool on hand, the disassembly process will be very laborious and time consuming, and there is a drawback that needs to be improved.
因此,有必要提供一種新穎且具有進步性之液壓式球接頭拆卸器,以解決上述之問題。Therefore, it is necessary to provide a novel and progressive hydraulic ball joint detacher to solve the above problems.
