样板是机械制造业和机修部门在生产过程中的重要检测工具。过去我们采用常规方法研制样板,精度差、效率低。最近,我们研制了一种积块式组合研具,实践证明该研具具有较大的适用性和广泛性。一、结构:研具主要由主座1、工作块3、4,备用块5、6,备用匣2组合而成。在四个 Model is the machinery manufacturing and mechanics sector in the production process of an important testing tool. In the past we used the conventional method to develop a model with poor precision and low efficiency. Recently, we developed a block block combination of research tools, the practice proved that the research tool has greater applicability and extensiveness. First, the structure: Research tools mainly by the main seat 1, work block 3,4, spare block 5,6, spare box 2 combination. In four
