80-140马力拖拉机拨叉类零件工艺改进分析

Process Analysis of 80-140 Horse Tractor's Fork Parts

拖拉机拨叉类零件是在变速箱中通过与变速手柄相连,拨动中间变速轮,改变拖拉机输入/输出转速比实现各档位间自由转换的关键零件。由于其独特的外形构造特点决定了在切削加工中,容易发生受夹持力产生变形,零件尺寸不稳定的情况。通过比较分析,改善加工工艺,解决拨叉类零件在切削加工中的加工难题,提升产品品质、提高加工效益。

The tractor fork parts are key parts that are freely connected in the gearbox by changing the input / output speed ratio of the tractor by connecting the shift wheel with the shift handle.Because of its unique shape and shape characteristics of the decision in the cutting process, it is prone to deformation by the clamping force,parts of the size of the situation.Through compara-tive analysis’to improve the processing technology and to solve the fork parts in the cutting processing problems can improve product quality and processing efficiency.
