我厂有台NP-75点焊机采用杠杆机构操作,其劳动强度较大,工效很低,工人宁可在NR-75点焊机上加班工作,也不用此机。为此,我们对NP-75点焊机做了如下改进:拆掉杠杆部分,在机身后部装上一个MZ91-45H制动电磁铁,它的连接杆与点焊机的三角形连杆相接(见图1、2),其线路与点焊机线路接通。线路中增设一变压器(12V),以保证安全。引出脚踏线到脚踏开关(见图3)。该机改进后,脚踏开关,电路接通;脚尖抬起,电路断开。提高工效五倍左右,并减少一
I have a plant in Taiwan NP-75 spot welding machine using the lever mechanism, the labor intensity is large, the work efficiency is very low, the workers prefer to work overtime on the NR-75 spot welding machine, do not use this machine. To this end, we NP-75 spot welding machine made the following improvements: Remove the lever part, the rear of the fuselage fitted with a MZ91-45H brake solenoid, the connecting rod and the spot welding triangle connecting rod phase Then (see Figure 1, 2), the line and spot welding line connected. Additional transformers (12V) in the line to ensure safety. Pull out the foot pedal to the foot switch (see Figure 3). After the improvement of the machine, the foot switch, the circuit connected; toe lifted, the circuit is disconnected. Increase efficiency about five times, and reduce one
