摘　　要：针对液压支架顶梁和掩护梁铰接孔销轴装配困难的问题,设计了一种全新的销轴装配装置。销轴装配装置采用模块化设计,能够提高销轴的装配效率,推进车间装配生产的自动化。使用ANSYS对装置进行静力学分析,得到应力和变形云图,通过分析云图得知,关键部件在极限工况能够正常工作;基于静力学结果对装置进行疲劳寿命评估,得到装置在10 kN负载下,最少工作次数为52254次,满足设计要求;并对装置进行模态分析,结果表明,销轴装配装置不会发生共振。通过现场试验验证,销轴装配装置运行良好,长期运行时销轴安装数量为6~8个/d,明显提高了工作效率。Aiming at the difficulty of assembling the pin shaft of the hinge hole of the top beam and the cover beam of the hydraulic support,a brand-new pin shaft assembly device is designed.The pin assembly device adopts modular design,which can improve the assembly efficiency of the pin and promote the automation of workshop assembly production.The Statics analysis of the device is carried out using ANSYS,and the stress and deformation nephogram is obtained.Through the analysis of the nephogram,it is known that the key components can work normally under extreme conditions.The fatigue life of the device is evaluated based on the Statics results,and the minimum working times of the device under 10 kN load is 52254,which meets the design requirements.And modal analysis was conducted on the device,and the results showed that the pin assembly device did not experience resonance.Through on-site testing and verification,the pin assembly device operates well,with a daily installation quantity of 6-8 pins during long-term operation,significantly improving work efficiency.
