Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, the present invention is expanded on further.
As shown in Figure 1, Figure 4 and Figure 5, a kind of special transformer aluminium row's processing unit (plant), including workbench 1, the bottom of workbench 1
Top of the both sides at end respectively with two pieces of supporting plates 2 is fixedly connected, and the both ends of the bottoms of two pieces of supporting plates 2 respectively with bottom plate 3 are consolidated
Fixed connection, the bottom of bottom plate 3 are installed with four pulleys 4 respectively, and the middle part and the bottom of cutting machine 5 on the top of workbench 1 are embedding
Close, the side on the top of workbench 1 is arranged with four screw rods 6, as shown in Fig. 2 four screw rods 6 respectively with two depression bars 7 two
The interspersed connection in end, the top of screw rod 6 are provided with adjusting nut 8, and the middle part of screw rod 6 is arranged with spring 9.
Two avris on the top of workbench 1 are arranged with two fixed stations 10, and the middle part on one of top of fixed station 10 is consolidated
Dingan County is equipped with switch panel 11, and the surface of switch panel 11 is respectively equipped with cutting machine controlling switch, electric expansion bar controlling switch
And motor controling switch, and the one end of the side of the fixed station 10 respectively with two electric expansion bars 12 is fixedly connected, two
Both ends of the other end of electric expansion bar 12 respectively with the side of clamping plate 13 are fixedly connected, and the bottom of another side of fixed station 10 is consolidated
Surely it is provided with scale strip 14.
The one end at the top of fixed station 10 is installed with motor 15, as shown in figure 3, the side of motor 15 is fixed with
Fixed plate 16, the bottom of fixed plate 16 are fixedly connected with the top of fixed station 10, and the top of fixed plate 16 is fixed with bearing 18,
One end of the output shaft of motor 15 and power transmission shaft 17 is connected, and the other end of power transmission shaft 17 is arranged on fixed plate through bearing 18
