Title:
SPOT WELDER TIP FOR PRECISION ELECTRODE FORCE PRESSURE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/000391
Kind Code:
A1
Abstract:
A spot welder tip for a precision electrode force pressure system. The tip comprises: a tip frame (101); a welding force drive shaft (102) installed on the tip frame (101), wherein one side of the welding force drive shaft (102) is connected, via a welding force drive clamp (105) tightly secured thereon, to a welding force providing device, and another end of the welding force drive shaft (102) is connected, via an electrode force drive clamp (106) tightly secured thereon, to an electrode force drive shaft (103); and a pressure sensor (107) tightly secured on the welding force drive shaft (103), wherein the pressure sensor (107) is provided with a securing end (113) secured to the welding force drive shaft (102) and with a force sensing end (114) distal from the securing end (113). The welding force drive shaft (102) is provided with a compression spring (109) pressing against the electrode force drive clamp (106). The force sensing end (114) of the pressure sensor (107) is provided with a buffering spring (108) pressing against the electrode force drive clamp (106). The spot welder tip can meet a precision requirement of a pre-configured electrode force necessary when performing spot welding on a small workpiece. The tip can also maintain a relatively constant electrode force within a pre-configured range for the entire period of a welding process.
