Specific embodiment
The invention will be further described below.
Embodiment 1：Referring to Fig. 1, Fig. 2, a kind of Special electric welding electrode for cell type part, including top electrode 3 and lower electrode
4, the top electrode 3 and lower electrode 4 are set on electric welding machine 1, and the top electrode 3 is equipped with electrode holder 5, the electrode holder
5 lower ends are equipped with upper electrode cap 6, and the lower electrode 4 is made of fixed plate 8 and support base 9, and the support base 9 is by horizontal extension
Portion 10 and vertical interconnecting piece 11 are constituted, and the extension 10 is in inverted "L" shape structure with interconnecting piece 11, and is integrally formed, described
10 front end of extension of support base 9 is equipped with the card slot for installing lower electrode cap 7,11 lower end of interconnecting piece of the support base 9 and fixation
Plate 8 is detachably connected, and the upper electrode cap 6 is located on same perpendicular bisector with lower electrode cap 7, is convenient for being welded.It is protected in spot welding
During dangerous this kind of box-shaped part of thick stick energy-absorption box, inverted "L" shape structure, can seat 9 easy to support 10 front end of extension from box-like zero
It is protruded at the bore of part, avoids box body thickness, then spot welding is carried out by upper/lower electrode 4.There is no need to use high spot welding
Robot designs curved polymorphic structure electrode without consideration.The stability of structure is good, and box-shaped part can be stably placed at
On support base 9.
Cooling water circulation passage 14, the card slot bottom and 14 bottom of cooling water circulation passage are equipped in the support base 9
Connection.Cooling water circulation passage 14 cools down lower electrode cap 7 convenient for squeezing into recirculated cooling water, improves dissipating for lower electrode cap 7
