可调整式“一面两销”定位装置的应用

Application of adjustable"one side two pins"positioning device

“一面两销”定位是机械加工中工件与夹具、夹具与机床定位方式中最常用的一种形式,介绍了一种可调整式“一面两销”定位装置的设计特点,通过定位销基座的方式完成定位销和机床夹具本体的连接,同时具有位置可调性,从而满足定位销的位置优化。相对于固定式“一面两销”定位装置,在专用夹具设计应用中具有较大的便捷性、优越性和兼容性,能够针对夹具定位误差进行补偿校正,有效地消除各种定位误差带来误差影响,提高一面两销定位精度,大大提高工件加工的位置精度。

"One plane and two pins"positioning is the most common mode of workpiece-fixture positioning and fixture-machine tool positioning.This paper introduces the design characteristics of an adjustable"one plane and two pins"positioning device,which can be used to connect the positioning pin with the machine tool fixture through the positioning pin base.The positioning device is also position-adjustable,facilitating optimized location of the positioning pin.Compared with the fixed"one plane and two pins"positioning device,this device features much greater operability,superiority and compatibility in the design and application of special fixtures,and can compensate and correct for the positioning error of fixtures to effectively eliminate the impact of various positioning errors,thereby improving the positioning accuracy of one plane and two pins positioning,and maximizing the positional precision of workpiece processing.
