Clamping Performance: The clamping device of the fixture must provide sufficient and stable clamping force to ensure that the workpiece will not shift or loosen during machining due to cutting forces, gravity, or other factors. Simultaneously, the clamping action should be flexible, reliable, and easy to operate.
Positioning Performance: The positioning elements must accurately determine the workpiece's position with good repeatability. That is, the workpiece's position in the fixture should be essentially consistent each time it is clamped to ensure the stability of machining accuracy.
Rigidity and Stability: The fixture must possess sufficient rigidity to withstand various forces during machining and must not exhibit significant deformation. Furthermore, the fixture must be placed stably, preventing wobbling or tipping during machining to ensure the safety and reliability of the machining process.
Interchangeability: If the fixture contains any wear parts or components that need periodic replacement, these parts must have good interchangeability. That is, the replaced parts can be used normally with other parts without affecting the overall performance of the fixture.
Clear Labeling: The fixture should have clear labeling, such as serial number, name, and applicable workpiece model, to facilitate operator identification and use, and also to facilitate fixture management and maintenance.
Ease of Operation: The fixture design should consider the ease of use for operators. For example, the clamping and releasing devices should be simple and labor-saving to operate, and the observation and adjustment of workpiece position should be convenient, minimizing the operator's labor intensity and operation time.
Good Maintainability: The fixture's structural design should facilitate daily cleaning, lubrication, maintenance, and troubleshooting. Disassembly and installation of various components should be convenient, and sufficient space should be provided for maintenance operations.
