Specific embodiment
Fig. 1 to Fig. 6 is please referred to, a kind of auxiliary transformer iron core auxiliary shaping tooling mainly adjusts device 1 by fastening, prevents
Rotating device 2, standard apparatus 3 form.Fastening adjustment device is mainly made of 4, threaded rods 5 of a round steel and pedestal 6；Bottom
Seat is cylindrical.The upper end of threaded rod is welded on the middle part of round steel, and pedestal is connected to the lower end of threaded rod.Fastening adjustment device
For entire tooling to be fixed on to the folder of auxiliary transformer, people exerts a force from round steel, and threaded rod couples standard apparatus, pedestal
It links together with anti-rotation device, when rotational fastener adjusts device, anti-rotation device will not rotate.Standard apparatus includes one
Body formed cross tube 9, vertical bar 10 and sheer pole 11, cross tube and sheer pole are connected to the upper end on the inside of vertical bar under
End, vertical bar medial surface are plane.Equipped with the threaded hole to match up and down and with threaded rod, threaded rod is logical at the middle part of cross tube
Thread connecting mode is crossed to be connected in the threaded hole of cross tube.Anti-rotation device connects pedestal, and is adjusted and filled by rotational fastener
Setting can be such that anti-rotation device moves up and down.Anti-rotation device includes column body 7 and the chassis 8 that is connected to below column body, upper prop
Cylindrical hole up and down is equipped in the middle part of body, the diameter of cylindrical hole lower part is greater than the diameter on top, cylindrical hole top
Diameter is greater than the diameter of threaded rod and is less than the diameter of pedestal, and the lower end of threaded rod passes through cylindrical hole top, and pedestal is located at circle
Cylindrical hole inside lower portions, and threaded rod and pedestal can be freely rotated in the cylindrical hole of column body.Due to clamp device
Pedestal can move freely in the inside of anti-rotation device and cannot skid off from the inside of anti-rotation device, therefore in rotational fastener tune
When engagement positions, the frictional force that the pedestal of clamp device generates is not enough to that anti-rotation device is driven to rotate together.It can also be by anti-rotation
