Multipoint floating compression structure

Abstract

The invention discloses a multipoint floating compression structure. The multipoint floating compression structure comprises a locating fixture and a workpiece pressing plate; a plurality of Y-shapedembedding grooves are formed in the top of the locating fixture; a plurality of compression blocks corresponding to the Y-shaped embedding grooves are molded at the bottom of the workpiece pressing plate; and a first pressure sensor and a second pressure sensor are fixedly arranged at the tops of the two ends of the locating fixture correspondingly in a seating manner. According to the multipointfloating compression structure, multi-fold type bow-shaped elastic bodies are machined on the compression blocks molded at the bottom of the workpiece pressing plate by wire cut electrical discharge machining and can be matched with the Y-shaped embedding grooves to effectively compress and fix all columnar workpieces; by adjusting insert depths of the upper part and the lower part of a hinge, workpieces in different sizes can be compressed, so that the universality of the multipoint floating compression structure is improved; and multipoint floating compression can be performed by adopting asingle part, and the multipoint floating compression structure is free from space limitation from the workpieces in different sizes, and is simple in structure and low in manufacturing cost.

Description

Technical field: [0001] The invention relates to the technical field of workpiece processing, in particular to a multi-point floating pressing structure. Background technique: [0002] During the machining or storage of columnar workpieces, it is often the case that multiple workpieces are pressed at the same time. The common pressing method is to set a positioning fixture on the lower part and fix it through the plate-shaped workpiece pressing plate on the upper part, but each There will be differences in the size of the columnar workpieces, some workpieces will be compressed and fixed, while other workpieces with slightly smaller sizes will be out of the compaction process, and it is difficult to ensure the compaction effect of all workpieces; [0003] In order to ensure the compression effect, a spring compression structure is installed on the plate-shaped workpiece in the prior art. This structure uses multiple springs to connect the pressing blocks to float and compress...

[0002] During the machining or storage of columnar workpieces, it is often the case that multiple workpieces are pressed at the same time. The common pressing method is to set a positioning fixture on the lower part and fix it through the plate-shaped workpiece pressing plate on the upper part, but each There will be differences in the size of the columnar workpieces, some workpieces will be compressed and fixed, while other workpieces with slightly smaller sizes will be out of the compaction process, and it is difficult to ensure the compaction effect of all workpieces;

[0003] In order to ensure the compression effect, a spring compression structure is installed on the plate-shaped workpiece in the prior art. This structure uses multiple springs to connect the pressing blocks to float and compress the columnar workpiece, which obviously improves the compression effect on the workpiece. The structure is complex, the production cycle is long, the cost is high, and it is difficult to realize due to space constraints when processing small-sized workpieces
