[0025] Please refer to Figure 1-6 , a manual pen-type resistance welding head in this embodiment includes a welding head housing 4. Inside the welding head housing 4, there is a welding head mandrel 1. A pressure fine-tuning adapter ring group 2 is sleeved on the outer surface of the welding head mandrel 1. A pressure adjusting ring group 3 is sleeved on the outer surface of the welding head mandrel 1. A limit snap ring 5 is sleeved on the outer surface of the welding head mandrel 1. A welding head body 9 is connected to the welding head housing 4. An adjusting ring 10 is arranged on the outer surface of the welding head housing 4. A handle bolt 8 is connected to the adjusting ring 10. A signal power cable harness group 6 is fixedly connected to the welding head body 9 through a fixing bolt 7.

[0026] Specifically, the welding head mandrel 1 includes a guide rod 101. On one side of the guide rod 101, there is a fixedly connected baffle plate 102. On the outer surface of the baffle plate 102, there is a fixedly connected contact piece 103. On the other side of the guide rod 101, there is a fixedly connected electrode 104. Among them, the electrode 104 is a screw-type electrode. The design of the screw-type electrode 104 makes the replacement and adjustment of the electrode 104 more convenient, reduces the maintenance time, and improves the usability of the equipment.

[0027] Specifically, the pressure fine-tuning adapter ring group 2 includes a connecting ring 201. The connecting ring 201 is sleeved on the outer surface of the welding head mandrel 1. On one side of the connecting ring 201, there is a fixedly connected first spring 202. The other end of the first spring 202 is fixedly connected to a locking ring 203.

On the outer surface of the adjusting column 301, there is a fixedly connected second spring 302. A pressure scale plate 11 is arranged on the welding head housing 4. By adjusting the welding pressure, current, and pre-pressing time, the splash phenomenon after the metal melts during welding can be effectively reduced.

[0028] Specifically, the signal power cable bundle group 6 includes an installation cover 601. The installation cover 601 is fixedly connected to the welding head body 9. A bracket 602 is fixedly installed on the installation cover 601. A microswitch 603 is fixedly installed on the bracket 602. A brake cable 604 is fixedly connected to the installation cover 601.

The design of the O-shaped terminal 606 can adapt to multiple connection methods, enhancing the system compatibility and meeting the requirements of different welding environments and equipment.

[0029] During implementation, the following steps are taken for operation: The pressure fine-tuning adapter ring group 2 and the pressure adjustment ring group 3 are sleeved on the outer surface of the welding head mandrel 1, and the welding pressure can be adjusted as needed. The adjustment ring 10 achieves precise pressure adjustment through the handle bolt 8 to ensure good contact during the welding process. The design of the limit snap ring 5 can ensure that the welding head mandrel 1 remains within a certain working range during the welding process, preventing excessive movement. The welding head body 9 is connected to the signal power cable bundle group 6 through the fixing bolt 7 to ensure that the current can be effectively transmitted to the electrode 104 of the welding head mandrel 1 to generate the heat required during welding. During welding, with appropriate pressure and current passing through the welding head mandrel 1, heat is generated between the electrode 104 and the material to be welded, melting and bonding the material at the contact point.
