基于大型农业机械的后桥壳体深孔加工装置设计
Design of Deep Hole Processing Device for Rear Axle Housing Based on Large Agricultural Machinery
摘要
Abstract
The axle housing parts are the substrate for the assembly of reducers,differentials,half shafts,and gears,mainly playing a supporting and protective role,and are widely used.In order to solve the vibration problem of deep hole machining on the rear axle housing parts of large agricultural machinery,a deep hole machining device for the rear axle housing has been designed.After analyzing the processing requirements and structural craftsmanship of the rear axle housing parts,the device is designed based on relevant theories of mechanical structure,hydraulic pressure and mechanical manufacturing.The device consists of four parts:a cutter bar device,a hydraulic elastic movable center device,a workpiece positioning and clamping device,a hydraulic device.When processing deep holes in the rear axle housing parts,the extension of the tool bar is too long,which can easily cause bending deformation and vibration during processing.The device adopts a hydraulic elastic center device,and the top point is pressed against the left end of the tool bar during processing,reducing the impact of radial force on the tool bar,avoiding the bending deformation of the tool bar and the generation of vibration during processing,thereby improving the machining accuracy of the parts.The tool speed and feed speed can also be adjusted accordingly,and both coarse and fine machining tools are installed on the tool holder.Deep holes can be processed in one go.After using the device,the processing time of deep holes is reduced from 40 minutes to about 2 minutes,and the processing efficiency of deep holes is increased by 20 times.关键词
