[0002] The oil pump gear is an important component for driving the oil pump in the internal combustion engine, and its main function is to deliver oil (lubricating oil) to each lubricating point of the engine to ensure the normal operation of the engine. The oil pump gear is usually composed of two gears that mesh with each other and is installed at the front bottom of the engine to drive the swing arm through a reduction device, thereby pushing the piston to move up and down to achieve the circulation lubrication of the oil in the engine. The precision blank turning of the oil pump gear refers to the machining under the condition of the blank state or a large difference from the target size, which is usually a machining process after rough turning. The main purpose of precision blank turning is to achieve all dimensions and technical requirements of the part to ensure that the geometric dimensions and surface roughness of the part meet the design requirements. When turning the gear face, the side surface needs to be fixed towards the turning tool. Since the outer edge of the gear is toothed, it is difficult to fix it firmly with the traditional clamping structure, which affects the accuracy of machining. Therefore, we need an oil pump gear precision blank turning device that can be firmly and conveniently fixed.
