在机械加工中 ,中小工件的加工量占绝大多数 ,生产中要通过多道工序才能完成其成品 ,在工序与工序之间必然会产生工件的撂放和周转的问题。过去传统的方法是将加工好的工件就地撂放 ,这样就造成生产场地混乱、加工好的工件磕碰情况时有发生、已加工好的加工面被破坏、工序之间 In machining, small and medium-sized workpieces accounted for the vast majority of processing, production through the multi-channel process to complete the finished product, between the process and the process will inevitably lead to the release and turnaround of the workpiece. In the past, the traditional method was to place the finished workpieces on site, thus causing chaos in the production site. Cracking of the finished workpieces occurred from time to time. The machined work surfaces were destroyed and the process was interrupted
