Description of drawings
Fig. 1 is this practical structural representation.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprise tighten, two stations are dashed in riveting, be arranged side by side in the front of cabinet.Tightening station comprises fastening device 1, goes up clamping and positioning device 2 and tightens clamping device 3; Riveting towards station comprise equipment for riveting and punching 4, riveting towards positioner 5 and riveting towards clamping device 6.
The fastening device 1 that tightens in the station comprises an electric twisting spanner 11, torque spanner 11 is supported on the spanner frame 12, spanner frame 12 is along the guiding mechanism guiding that is located on the cabinet panel, drive by spanner frame cylinder 13, when spanner frame cylinder starts, can drive spanner support 12 and torque spanner 11 and together move.Torque spanner 11 can also be to be slidingly installed on the spanner frame, drive on the spanner frame by a fine setting cylinder and move, like this, but under spanner frame cylinder drives the position of coarse adjustment spanner, under the drive of fine setting cylinder, can accurately aim at spanner and restore the position of nut.
