指接机端面铣削部分设计
摘 要

本次设计的指接机端面铣削部分是应用于普及型欧式木窗加工的专用设备，通过指接技术降低类似于欧式木窗的木工产品的生产成本，提高其市场竞争力。
通过对国内外指接设备的分析，在考虑生产成本的基础上，设计了能够满足一般指接需求的设备，并根据较小尺寸对刀具系统进行了完善，使本机床的刀具系统适用较小截面尺寸的木工产品的指榫加工。刀具主轴转速较高，并承受一定的扭矩，文中对其进行了受力分析，确保其在生产中的安全性，同时对其附属部分，如带传动和轴承等进行了校核计算。木材原料夹紧机构采用弹簧压紧，对弹簧力进行了分析，确保在最省力的情况下使木材原料顺利加工。
本题目从生产实际出发，为小径木材指榫加工设计关键设备，对现有的指接机进行改进设计，降低指接生产线成本，使指接技术得以普及。对于我国中小型木工企业的生产改型和技术革新有重要的意义。

ABSTRACT

The machine that we designed is a milling installation which is used for the machining of the popularized western-style wooden window. By applying this kind of knowledge, we could reduce the production costs of those products as western-style wooden window and enhance its competitive power.
Through the analysis of both the domestic and the foreign tenoners and on the basis of the consideration of its production costs, we have designed this kind of equipment which could meet the need for the joint of general tenon need raw materials and have made approve-ments to its tool system. Through this change, we have made its tool system more applicable for the joint of those products in smaller section size. The tool’s primary shaft works in higher rotational speed and withstands certain torque. We have carried out the force analysis in this article to make sure its security and have made checkouts to its accessorial parts, such as transmission belt and transmission shaft and so on. Through the analysis of the spring force, we uses the spring to compact in the lumber raw material jig system to make sure that the lumber raw materials could clamp smoothly in the situation which uses the minimum forces.
Combined from infact of product, this topic is set up both for the design of the key equipments which are used for the machining of this small materials and to make approvements to the existing tenoners so as to reduce the costs of the connect production line and to make this technique popular. With regard to our middle and small carpentry enterprise's production modification and technical innovation, this design has quite a vital significance.
