高压离心式水泵是我厂近年来的主导产品之一。水泵中轴瓦体(附图点画线部分外圆球面)是关键零件,它质量好坏直接影响着水泵的性能和寿命。轴瓦体(外圆球面)结构复杂、工序多、周期长。按照过去的加工方法是用靠模粗车外圆球面后再精磨。这种工艺效率低、质量差、劳动强度大、粉尘多。为了改善加工条件和操作环境,我们设计了一套安装在C620车床上的粗、精铣轴瓦体外圆球面加工装置。采用该装置对外圆球面粗、精铣可一次加工完成。经几年使用,效果显著,较原计划工时提高工效8倍多,且质量稳定可靠、操作简便、降低了劳动强度。现介绍如下。
High-pressure centrifugal pump is one of our factory leading products in recent years. Water pump bearing body (drawing dotted line part of the outer spherical surface) is the key components, it is a direct impact on the quality of the pump performance and life expectancy. Bearing body (spherical outer spherical) structure is complex, multi-process, long cycle. In accordance with the past, the processing method is to rely on the rough car outside the spherical surface after grinding. This process is inefficient, poor quality, labor-intensive, dust and more. In order to improve the processing conditions and operating environment, we designed a set of coarse and fine milling bearings installed in the C620 lathe body spherical spherical surface processing device. Using the device on the outer spherical surface rough, fine milling can be completed once the processing. After several years of use, the effect is remarkable, which is 8 times more ergonomic than the original planned working hours. Besides, the quality is stable and reliable, the operation is simple and the labor intensity is reduced. Now introduced as follows.
