基于Pro/E和ANSYS的木工铣削刀具用液压夹紧轴套薄壁结构的设计

Pro/E and ANSYS-based Design of the Thin Wall Structure of Hydraulic Clamping Sleeves for Woodworking Milling Cutters

增加刀轴转速,提高进给速度是当今木材加工设备发展的方向之一。液压夹紧轴套是四面刨、双端铣等木材高速加工设备上普遍采用的刀具装夹设备。依据摩擦连接理论和材料弹塑性变形理论得出液压夹紧轴套的壁厚计算模型,并根据计算结果采用Pro/E软件建立了液压夹紧轴套的三维实体模型,通过ANSYS软件对模型的关键部位进行了有限元验证分析。结果表明:液压夹紧轴套壁厚计算模型是合理且可靠的,可以用来进行产品的优化设计。

One of the development trends of woodworking equipment is to increase spindle speed and feed speed.Hydraulic clamping sleeves are the cutting tool clamp equipment universally used in high-speed woodworking equipment like four-side planers and double-end tenoners.Based on the friction joint theory and material elastic-plastic deformation theory,a wall thickness calculation model of hydraulic clamping sleeves is obtained and according to the calculation result,a 3D solid model of the hydraulic clamping sleeves is established using Pro/E software and through ANSYS software,finite element verification analysis of the key parts of the model is made.The result shows that the wall thickness calculation model of hydraulic clamping sleeves is rational and reliable and can be used for the optimal design of products.
