组合夹具的精度直接影响制件的质量,因此,组合夹具的精度问题关系到它是否有生命力的基本问题。一般来说,组合夹具是按 H7/h6(D/d)精度要求制作的,它一般适用于 H8/h7(D3/d3)以下精度零件的加工。为了保证和提高制件的加工精度,必须具体地对组合夹具在使用中可能产生的误差进行分析,并针对各误差产生的环节找出提高精度的办法。一、影响零件加工精度的误差因素用组合夹具在机床上加工工件时,影响
The accuracy of the combination fixture has a direct impact on the quality of the part, so the accuracy of the combination fixture concerns the basic question of whether it has vitality. Generally speaking, the combination fixture is made according to the requirement of accuracy of H7 / h6 (D / d). It is generally suitable for the processing of parts with the following accuracy of H8 / h7 (D3 / d3). In order to ensure and improve the processing accuracy of the workpiece, it is necessary to analyze the possible errors in the use of the fixture in detail and to find out ways to improve the accuracy of each error. First, the impact of parts machining accuracy of the error factors Combination of the fixture on the machine when processing the workpiece, the impact
