Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and in particular to a dual-station clamping fixture for cylindrical workpieces. Background Technology

[0002] In machining, automated assembly, and testing, clamping cylindrical workpieces is a common process requirement. Traditional clamping methods typically employ single-station fixtures, using manual or pneumatic methods to position and fix the workpiece. However, with increasing demands for production efficiency and the development of automation technology, single-station fixtures can only clamp one workpiece at a time, requiring frequent loading and unloading during machining or testing. This results in long production cycles, making it difficult to meet the demands of high-volume, high-cycle production. For cylindrical workpieces of different diameters or lengths, single-station fixtures often require changing the grippers or adjusting the structure, exhibiting poor adaptability and impacting the efficiency of switching between different product types. Therefore, we have redesigned a dual-station clamping fixture for cylindrical workpieces. Utility Model Content
