立木地板加工机床
--成型机分度机构

内容提要

随着天然林的禁伐，以多年生直径大多在Φ300mm以上的木材为主木制地板,价格见长，急需新的原材料来替代。所以对树木修剪下来的树枝及小树干等小径材(直径在Φ200mm以下)的利用就成为了一个新兴的研究方向。
立木地板加工机床就是以加工立木为主的木工机械,与传统的顺木地板加工机床有所不同,它以小径材(直径在Φ200mm以下)木料为加工对象,将其径向切削成小块马赛克，然后拼装成大块地板投放市场，具有很大的市场前景。本次毕业设计中，我的题目便是“立木地板加工机床——成型机分度机构”。成型机主要是负责对原料的成型加工，将不规则的外形加工成规则的几何图形。这些图形中的角度就是由分度机构带动夹具转动后切削产生的。我的设计方案是“棘齿式分度机构”，它结构简单，操作方便，只需要扳动手柄就可同时实现两个夹具的分度，其加工效率较高，适用于大量加工。而且维修方便，价格便宜。

ABSTRCT

With the ban natural forest to grow> 300mm in diameter are mainly wood and wood floors, prices are growing at the new raw materials need to replace. So to trim down the branches and small trees such as footpaths thin trunks (> 200mm in diameter below) use has become a new research direction.
Stumpage floors processing machine tools is mainly to the processing significantly Woodworking Machinery, and the traditional wooden floors Shun processing machine tools are different, it tracks wood (> 200mm in diameter below) for the wood processing objects, its radial cut into small tiles, and then assembled into a large floor put on the market, the market has great prospects. This graduate design, my topic is "significantly floors processing machine tools -- shaped machine hours for institutions." Shaped primarily responsible for the processing of raw materials shaped to irregular shape processing rules into the geometric figure. These graphics are from the perspective of institutions to sub-degree turn after cutting a jig. My design is the "savage teeth-hours for institutions," it simpler, easy to operate, need only be accompanied by two jig trigger handle sub-degrees, the higher the efficiency of processing, applicable to a large number of processing. And maintenance convenience, cheaper prices.
