Description

Hydraulic ball joint remover

This invention relates to a detacher, and more particularly to a hydraulic ball joint detacher.

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.

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.

Therefore, it is necessary to provide a novel and progressive hydraulic ball joint detacher to solve the above problems.
