摘　　要：针对小型扁平焊接零件的装夹效率低问题,在不采用自动控制的情况下,设计一套实用的快速装夹方案,提升生产效率。以一个常见的小型焊接零件为例,通过定位机构设计、夹具体设计和夹紧机构设计,完成整套夹紧机构设计,能同时实现4组焊接件的装夹。最后将本装夹机构与普通虎钳机构的装夹效率进行对比试验。结果显示,采用本装夹方案每分钟完成装夹数由原来的1.09 pcs/min提升到21.8 pcs/min,大大提升焊接工艺的生产效率。Aiming at the low clamping efficiency of small flat welding parts,a practical fast clamping scheme is designed without automatic control to improve the production efficiency.Taking a common small welding part as an example,the whole set of clamping mechanism design is completed through the design of positioning mechanism,clamp specific design and clamping mechanism,which can realize the clamping of four groups of welding parts at the same time.Finally,the clamping efficiency of this clamping mechanism is compared with that of ordinary vice mechanism.The results show that the clamping number per minute is increased from 1.09 pcs/min to 21.8 pcs/min,which greatly improves the production efficiency of the welding process.
