The invention provides a press mounting device for a front oil seal for a crankshaft. The press mounting device comprises a press mounting part and a handle used for supporting the press mounting part, wherein a first round hole is formed in the first end of the press mounting part; the front oil seal sleeves the outer part of a placing block; the placing block is in sliding matching with the first round hole; a second round hole is formed in the second end of the press mounting part; and the front end of a bolt shaft penetrates through the second round hole and the first round hole and is matched with an inner hole of the placing block. When the press mounting device is used, the front end of the bolt shaft is gradually screwed into a bolt hole of a crankshaft; and when the placing block is in contact with the end surface of the crankshaft, the bolt shaft is continuously screwed, and at this moment, the end surface of the crankshaft applies thrust to the placing block to make the placing block to move into the first round hole, so that the front oil seal which sleeves outsides the placing block is successfully transited to the front end of the crankshaft, and press mounting is finished. The press mounting device has a simple structure, is convenient in operation and can stably and reliably realize press mounting of the front oil seal of the crankshaft, and thus the assembly efficiency is improved, and the production takt is accelerated.
Description
technical field [0001] The invention relates to the field of engine assembly tools, in particular to a crankshaft front oil seal pressing device. Background technique [0002] The front oil seal of the engine crankshaft is installed at the front end of the engine crankshaft to prevent leakage of lubricating oil in the crankcase and prevent dust from entering the crankcase. Whether the installation of the front oil seal of the engine crankshaft is qualified or not has a crucial impact on the overall performance of the engine, so it is particularly important to design an easy-to-operate pressing tool for sealing the front oil to the front end of the crankshaft. [0003] In the prior art, manual press-fitting tools are generally used to press-fit the front oil seal, such as Figure 1a and 1b As shown, the pressing tool includes a support base 1', a push sleeve 2', a first bolt 3', a second bolt 4' and a rocker mechanism 5', wherein the rocker mechanism 5' cooperates with the f...
