Technical Field

[0001] This utility model belongs to the field of piston processing technology, and specifically relates to an auxiliary device for piston processing. Background Technology

[0002] When machining the piston end face, stable positioning and support of the piston are required to ensure machining accuracy. Traditional piston positioning devices typically employ a fixed structure, which is difficult to adapt to the machining requirements of pistons of different sizes. In particular, when there are differences in the height and position of the piston pin hole, existing devices are often inconvenient to adjust, leading to inaccurate positioning and affecting machining quality.

[0003] In existing technologies, while some piston positioning devices possess certain adjustment functions, their complex structures and cumbersome operations, coupled with a lack of effective limiting and fixing mechanisms, make them prone to displacement during processing, leading to machining errors. Furthermore, traditional support structures have limited adjustment ranges, failing to flexibly adapt to the support requirements of different piston models, thus increasing the time and difficulty of machining and adjustment.

[0004] Therefore, it is necessary to design a piston machining auxiliary limiting device that is simple in structure, flexible in adjustment, and stable in positioning, so as to improve the accuracy and efficiency of piston end face machining. Utility Model Content
