Embodiment
Below by non-limiting example, the utility model is expanded on further, understands the utility model.
As described in Fig. 1-3, a kind of multiple spot carbon brush cuts aluminium device, including sequentially connected alternating current generator 4, silk cylinder left end to electricity
Seat 1, wire storage tube 2, silk cylinder right end base 3, silk cylinder left end seat 1 is interior to be included positioned at the conductive copper 11 of center and around conduction
11 equally distributed three carbon brush of copper ring are tight with conductive copper 11 respectively to one end of electric installation 12 to electric installation 12, three carbon brush
Close contact connectio, the other end are separately mounted on three faces of silk cylinder left end seat 1.
Carbon brush to electric installation 12 include power cord 121, be connected with 121 one end of power cord carbon brush 122, be set in power cord
Compression spring 126 on 121, carbon brush 122 are provided outside carbon brush guide sleeve 123, and the other end brush head of carbon brush 122 is led beyond carbon brush
To the end face of set 123, the other end of power cord 121 is equipped with tail end protective case 124, and 121 other end of power cord is protected beyond tail end
The end face of set 124, is equipped with transition connector sleeve 125 between carbon brush guide sleeve 123 and tail end protective case 124, compression spring 126 is located at
In transition connector sleeve 125,126 one end of compression spring is against 122 end face of carbon brush for being connected with power cord 121, and the other end passes through locking
