Description

Technical Field

[0001] This utility model relates to the field of electronic stamping die assembly technology, specifically to an electronic stamping die guide post fixing block mounting fixture. Background Technology

[0002] During the assembly of electronic stamping dies, multiple guide pillars need to be arranged on the stripper plate. To ensure that the guide pillars can be reliably and accurately installed without wobbling, guide pillar fixing blocks are set on the upper surface of the guide pillars relative to the stripper plate. The guide pillar fixing blocks are installed corresponding to the positioning grooves of the stripper plate. The guide pillar fixing blocks are connected to the external thread of the guide pillars by threads. In actual assembly, when the guide pillar fixing blocks are finally tightened, since they have already been partially embedded into the positioning grooves in the height direction, it is difficult to tighten the protruding part of the guide pillar fixing blocks in the height direction using existing wrenches and drive mechanisms. As a result, a height gap will remain between the lower surface of the existing guide pillar fixing blocks and the upper surface of the positioning grooves. This can cause the guide pillars to wobble during die operation. Since electronic stamping dies have high precision, this situation will prevent the die from producing precision products. Therefore, there is an urgent need to develop a fixture for installing guide pillar fixing blocks to ensure that the lower surface of the guide pillar fixing blocks and the upper surface of the positioning grooves fit precisely. Utility Model Content
