根据市场需求 ,我厂叠加阀产量逐渐加大 ,这就要求各道工序在保证质量的前提下提高生产效率。产品中主要部件阀体的阀孔机加工是一道关键工序。以前所用的夹具存在调整难、通用性差、效率低、质量难以控制等缺点 ,制约了产量的提高和废次品率的降低 ,成为生产过程中的瓶颈问题? According to the market demand, our plant stacking valve output gradually increased, which requires that all processes in ensuring the quality of the premise to improve production efficiency. Valve body machining of the valve body, the main component of the product, is a key process. Fixtures used before there is the difficulty of adjustment difficult, poor versatility, low efficiency, difficult to control the quality and other shortcomings, restricting the increase in production and reduce the rate of waste defective, a bottleneck in the production process?
