This utility model relates to a flanging device for the outer ring of a full complement needle roller bearing. It includes an operating table with a base fixed to the right end of the table panel. The base has a support seat that can be adjusted left and right, and a mounting plate that can be adjusted up and down is located on the left side of the support seat. A pneumatic chuck is mounted on the mounting plate to hold the outer ring of the needle roller bearing. Two rollers, spaced apart, are rotatably mounted on the left end of the operating table panel. The inner side of each roller has a pressing bevel corresponding to the flanging surface of the outer ring of the needle roller bearing. This utility model employs a flanging method where the bearing does not rotate, but the rollers rotate. Therefore, the needle rollers installed in the outer ring of the bearing will not fall out during the flanging process, thereby improving the flanging efficiency and ensuring that the performance of the needle roller bearing is not affected.

The utility model belongs to ignition coil production technical field, specifically speaking is a kind of ignition coil performance detection device for electric injection;Through the setting push board, glass cover, air filter screen and fan, according to the ignition coil shape opening can be positioned groove to its hold, the ignition coil is inserted into the inside of positioning groove and is limited, ensure that the energized end of ignition coil after limiting is upwards, and the belt moves to drive movable frame, lifting frame and the ignition coil inside to move to align power-on detection component, through the rising of push board, make lifting frame and the ignition coil inside move to the inside of glass cover, then through fan and extract air, the air that enters the inside of glass cover is filtered through air filter screen, to remove dust, continue to lift ignition coil, so that ignition coil and power-on detection component butt joint and carry out power-on detection, after detection, pull out ignition coil, place qualified ignition coil and unqualified ignition coil respectively, so that dust is not easy to influence device detection.
