【摘要】：针对企业发动机油底壳多使用单轴或双轴拧紧机进行拧紧,用于装配线上大批量生产时效率相对较低的问题,设计了一种用于发动机油底壳螺栓联接的四轴拧紧机,采用丝杆螺母机构和导轨滑块机构设计,通过四个拧紧轴前后、左右、上下移动,同时同一部分上的两拧紧轴一个可相对于另一个固定的拧紧轴移动,能同时拧紧四个不同间距和不同中心距的螺栓组。用ANSYS Workbench对拧紧轴底板进行了有限元分析,结果表明其强度和变形都满足设计要求。该拧紧机用于发动机油底壳装配线工作范围大,生产效率高,拧紧质量可靠,能很好的保证油底壳良好的密封性能。
[Abstract]:The single or double shaft tightening machine is often used to tighten the oil bottom of the engine in the enterprise, which is used in the assembly line to produce relatively low efficiency in mass production. A kind of four-axis tightening machine is designed for the bolt connection of engine oil bottom shell. It adopts the thread rod nut mechanism and the guide rail slider mechanism to move up and down through the four tightening shafts before and after tightening. At the same time two tightening shafts on the same part may be moved relative to the other fixed tightening shaft. The bolt groups with four different spacing and different center distance can be tightened simultaneously. The finite element analysis of tightening shaft bottom plate is carried out with ANSYS Workbench. The results show that the strength and deformation meet the design requirements. The tightening machine is used in the assembly line of engine oil pan with large working range, high production efficiency, reliable tightening quality and good sealing performance.
