Pawl.
The two sides of the briquetting are provided with knob.
Compared with prior art, the utility model has the following beneficial effects:
1, the utility model includes pedestal and pressure head, and column is provided on pedestal, is provided with connector on column；The pressure
The top surface of head is horizontal plane, and inclined bottom surface is arranged, and the angle between top surface and bottom surface is the centripetal angle of centripetal magnetic pole；This is practical new
Type is placed at the top of centripetal magnetic pole after a side of centripetal magnetic pole is placed on pedestal, then by pressure head, due to pressure head inclined-plane
The special designing of angle ensure that the top surface of pressure head is in a horizontal position always after mounting, therefore by force analysis it is found that working as
When pressure head is by pressure straight down, the pulling force that cross component force is connected head is offset, to avoid centripetal magnetic pole lateral
Centripetal pole lamination, which is drawn, under the action of component runs, and ensure that the alignment quality of centripetal magnetic pole.
2, the connector of the utility model and column is angled is obliquely installed, and tilt angle size is that centripetal magnetic pole is centripetal
The half at angle guarantees that after centripetal magnetic pole and connector installation, the axis of connector is axially coincident with centripetal magnetic pole, to increase
Contact area between big connector and centripetal magnetic pole improves effective forced area of connector, protects connector, extends equipment
Service life.
3, the bolt hole being mutually matched and waist hole are provided between the column and connector of the utility model, facilitate according to
Alignment is improved to guarantee that connector is in best operational position always in the position of the flexible in size adjustment connector of heart magnetic pole
Quality.
4, the utility model uses dove-tail form claw between pressure head and centripetal magnetic pole, is between connector and centripetal magnetic pole
T shape claw makes straightening equipment preferably adapt to the shape of centripetal magnetic pole, improves the company between pressure head and connector and centripetal magnetic pole
Intensity is connect, guarantees the stabilization of centripetal magnetic pole in detection process, had both improved the quality of alignment, while avoiding sliding because of centripetal magnetic pole
Caused safety accident improves the safety of equipment.
5, the utility model is provided with knob in the two sides of pressure head, passes through knob after the completion of the alignment at a position and pulls
Pressure head slides into another position for needing to be straightened, to reduce the operation difficulty of equipment, improves alignment efficiency.
