Abstract: Due to the increasing proportion of bolted connection in heavy trucks, the tightening torque can not be guaranteed by using pneumatic wrenches in the workshop. It must be tested with a torque wrench before we know whether it is up to the standard or not. If it does not reach the standard, it needs to be repaired and re-tested, which seriously affects the production beat and has a large production noise. It is necessary to select a tool, which can not only ensure the tightening torque of bolts but also meet the requirements of noise reduction. Through the comparison of various types of fastening tools on the market, first of all, the suitable tools are determined and the hoisting mode of tools is designed according to the production site. Then the tightening experiments of various types of bolts are compared, and the bolts that meet the requirements are selected. Finally, it is confirmed that this process mode meets the production needs, when the bolt tightening torque reaches the set value, the equipment will prompt feedback to stop rotation, the bolt tightening torque does not need to be tested, and the production beat can be improved. The sanitary limit of noise level is guaranteed to be less than 85 decibels, which meets the noise requirements of the national production and assembly workshop.

Key words: tightening bolts; tightening torque; production noise

摘要: 由于重卡中采用螺栓连接占比越来越大,车间使用风动扳手紧固螺栓无法保证拧紧力 矩,必须用扭力扳手检测后,才知道是否达标,如不达标还需返修后重新检测,严重影响生 产节拍且生产噪声大。需要选取一种工具,既能保证螺栓拧紧力矩还需满足降噪的要求,通 过市面上各种型号紧固工具对比,首先确定适合要求的工具以及根据生产现场设计工具吊装 模式,再对各型号螺栓进行紧固实验对比,选择满足要求的螺栓。最后确认此种工艺模式满 足生产需要,当螺栓拧紧力矩达到设定值时,设备就会提示反馈停止转动,螺栓拧紧力矩无 需再进行检测,可提升生产节拍,噪声声级卫生限制保证在 85 分贝以内,满足国家对生产装 配车间的噪声要求。
