Basic knowledge of CNC machining fixture design
Machine tool fixtures must meet the following basic requirements: 1. The machining accuracy of the workpiece must be guaranteed. The key to ensuring the machining accuracy lies in the correct selection of positioning datum, positioning method and positioning components. If necessary, positioning error analysis is also required, and attention needs to be paid to the structure of other parts in the fixture for processing The impact of accuracy, to ensure that the fixture can meet the requirements of the machining accuracy of the workpiece. 2. The complexity of the special fixture for improving production efficiency should be adapted to the production capacity, and various quick clamping mechanisms should be used as much as possible to ensure convenient operation, shorten auxiliary time, and improve production efficiency. 3. Good process performance, simple and reasonable structure requirements for special fixtures, easy to manufacture, assemble, adjust, inspect, maintain, etc. 4. The
