Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of processing positioning, in particular to a processing positioning holding mechanism. Background Art
[0002] The existing enterprises in the hydraulic field have continuously improved the processing accuracy, processing quality requirements and processing difficulty of their products. The corresponding requirements for processing hardware such as equipment, tooling and cutting tools have also increased accordingly. In particular, it is particularly important to plan a more stable processing technology and produce a corresponding stable tooling clamping and positioning method. For example, when processing larger shell-type workpieces such as bearing shells, when using horizontal processing technology, the clamp is required to have sufficient positioning rigidity to meet the workpiece's 6-point positioning principle and the corresponding holding mechanism. The workpiece adopts a multi-station low-cost and high-efficiency design principle, but this will cause the clamping space of the fixture positioning to become smaller, which will limit the space for workpiece positioning and holding, making it inconvenient to operate.
[0003] In order to solve the shortcomings of the existing technology, we propose a processing positioning and holding mechanism. Utility Model Content
