目前,机械产品在迅速发展,大批量生产典型零件如套、圈类工件,在零件上的钻孔,已进入自动化,但由于一些厂家受到设备等方面的限制,虽保证了产品质量但生产效率不高。如我厂铜、铝合金有色金属衬套中钻削油孔,加工尺寸要求并不高,但一般夹具都根据心棒定位,螺旋机构夹紧来制造夹具,生产效率受到了一定限制。本夹具(见附图)的设计比原来夹具能提高工效一倍多,工件自动进入定位,夹紧,加工之后自动落下。进料、出料同步进行,大大缩短了辅助时间,适应于大批量的加工生产。一、工作原理首先根据图纸加工尺寸要求,调整钻模套与定位端面尺寸的位置距离,调试好夹具尺寸之后,用板手 At present, the rapid development of mechanical products, mass production of typical parts such as sets, ring type parts, drilling in the parts, has entered the automation, but due to some manufacturers by the equipment and other aspects of the constraints, while ensuring product quality but production efficiency not tall. As I plant brass, aluminum alloy liner drilling holes, processing size requirements are not high, but the general fixture according to the mandrel positioning, screw clamp to create the fixture, the production efficiency has been subject to certain restrictions. The fixture (see photo) design than the original fixture can improve work efficiency more than doubled, the workpiece automatically enter the positioning, clamping, automatic fall after processing. Feeding, discharging simultaneously, greatly reducing the auxiliary time, adapted to large quantities of processing and production. First, the working principle First of all, according to drawings processing size requirements, adjust the position of the distance between the drill sleeve and the positioning end face size, adjust the size of the fixture, the wrench
