| 摘 要： | 针对目前市面上加工小径木的机器加工精度低、效率不高、出材率低等问题，分析提高小径木梯形板出材率、加工效率及加工精度的设计方法，通过新的设计方法制定了新的加工工艺。结合工艺分析设计了小径木梯形板锯刨机的总体结构，可以对小径木梯形板进行锯切、粗刨、精刨加工。在对其核心组件锯切组件与刨削组件的加工原理进行分析的基础上，设计了锯切组件结构与刨削组件结构。通过导入锯切主轴SolidWorks的三维模型，利用ANSYS对其锯切主轴进行静力学分析，得到锯切主轴的应力、应变和变形云图，其中最大应力值为7.435 MPa、最大应变值为0.042 316 mm/m、最大变形量为0.002 178 8 mm，其强度、刚度及变形量均在许用范围内，仿真验证了锯切主轴的设计的合理性。

| Abstract: | Aiming at solving the problems of low precision,low efficiency and low yield of wood processing machines available in the market when they are used to process small diameter lumber,a new machine-designing method was discussed to improve the yield,machining efficiency and precision during processing trapezoidal plate from small diameter lumber,from which the new processing technology was formulated.The overall structure of the machine was designed based on process analysis.The machine could accomplish sawing,rough and fine planing for processing trapezoidal plate from small diameter lumber.Based on the analysis of the machining principle of the sawing and planing components of its core components,the structures of the sawing and planing components were designed.By introducing the three-dimensional model of SolidWorks of sawing spindle and using ANSYS to carry out static analysis of its sawing spindle,the stress,strain and deformation nephograms of sawing spindle were obtained.The maximum stress value was 7.435 MPa,the maximum strain value was 0.042316 mm/m and the maximum deformation was 0.0021788 mm.Therefore,the strength,stiffness and deformation of sawing spindle were within the allowable range.The simulation verified the rationality of the design of saw cutting spindle. |
