刻楦机长度扩缩机构对鞋楦扩缩精度的影响

Influence of the Length Expanding and Shrinking Mechanism on the Machining Precision of Shoe Last

长度扩缩机构是刻楦机在鞋楦加工中保证长度扩缩及精度的一种装置,文中通过对其原理分析,推导出长度扩缩摆角公式,进而分析机构对扩缩精度的影响,目的是为长度扩缩机构和分度机构的设计提供理论依据。

Expanding and shrinking mechanism of length is a kind of mechanism which ensure expanding and shrinking length and precision in shoe last machining. The paper analyses the working principle and deduces the swing angle formula of expanding and shrinking length. And analyses the influence of the mechanism on the expanding and shrinking precision. In order to provide theory assistant for design of the expanding and shrinking mechanism of length and the indexing mechanism.
