The invention discloses a loading and unloading tool of an internal thread pin and a using method thereof. The loading and unloading tool comprises a pin puller rod, a quick-changing pin pulling head, a bolt and a sliding knocking handle, wherein a lug boss is annularly arranged nearby one end of the pin puller rod along the axial direction, and the inner side surface of the lug boss is taken as an upper knocking surface; the rapid-changing pin pulling head comprises a connecting sleeve, one end of the connecting sleeve is opened, and is matched with the other end of the pin puller rod; a connecting through hole is formed in the side wall of the connecting sleeve, and the connecting sleeve is provided with a locking pin extending into the connecting sleeve; the end surface of the opening side of the connecting sleeve is taken as a lower knocking surface; the bolt is matched with the internal threads of the pin, and is arranged at the center of the end surface of the other side of the connecting sleeve; the sliding knocking handle sleeves the body of the pin puller rod. According to the loading and unloading tool of the internal thread pin, the assembly of the pin with the internal threads of an automobile tool can be realized, the assembly operability of the pin can be promoted, and the injury of hands and damages to products caused by careless knocking can be prevented.
Description
technical field [0001] The invention relates to mechanical assembly technology, in particular to a loading and unloading tool for internally threaded pins and a using method thereof, which is suitable for the assembly of automobile tooling. Background technique [0002] In the traditional method of assembling pins with internal threads, first hold the pin with one hand and align it with the pin hole, then use the other hand to hold a hammer and knock at the other end of the pin, when the pin slowly enters or is about to completely enter the pin hole When it is flush with the end face of the hole, in order to prevent the workpiece from being damaged, it is necessary to find a cylindrical metal piece such as a metal pin or a screw that is thinner than the pin, and strike the exposed end of the pin until the pin is completely inserted into the hole. If there is abnormality in the assembly of the workpiece, the pin must also be removed. At this time, it is necessary to knock fro...
