振动压路机的隔离环是一种典型的薄壁环形零件，由于该件的壁厚较薄，在夹紧力的作用下极易产生变形，因而零件的设计精度难以保证，严重影响部件的装配质量。如何使这类薄壁环形零件在批量生产中减少变形，提高零件质量的稳定性及加工效率，是一个普遍存在的难题，我们对此进 Vibration roller isolation ring is a typical thin-walled ring parts, due to the thin wall thickness of the piece, under the action of the clamping force easily deformed, so the design accuracy of parts is difficult to guarantee, seriously affecting the assembly quality of the components . How to make such thin-walled ring parts reduce the deformation in mass production, improve the stability of parts quality and processing efficiency, is a common problem, we are
