Abstract

The invention discloses a welding mechanism with a lifting device. The welding mechanism comprises an installation frame, wherein a welding head and the lifting device for driving the welding head to move vertically are arranged on the installation frame, the lifting device comprises a lifting air cylinder and a vernier device, the lifting air cylinder is provided with a piston rod coaxial with the welding head, and the vernier device is arranged between the piston rod and the welding head. The welding mechanism with the lifting device has the advantages of being high in regulation accuracy, accurate in center positioning and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of spot welding machines, in particular to a welding mechanism with a lifting device in the spot welding machine. Background technique [0002] Spot welding machines usually use the principle of resistance heat to melt solid metal to form solder joints to weld low-voltage electrical appliances such as moving contacts, static contacts, wiring boards and guard plates in switch parts. The welding device in the spot welding machine includes an upper welding head and a lower welding head. In order to meet the welding needs of different accessories, the lower welding head is usually equipped with a lifting device that can adjust its height. Traditional lifting devices such as figure 1 As shown, the lifting cylinder is connected under the lower welding head. The lifting cylinder is fixed on the mounting plate of the welding device. There are mounting screws on the mounting plate. One end of the screw is fixedly co...
