Specifically, the locking nut 12 adjusted on mandril 13, is the locking nut 12 of adjustable state, the lock
Tight nut 12 is that the locking nut of regular hexagon may be implemented locking nut during the concentric adjustment of subsequent deflector roll
The adjusting of different conditions meets more demands.
Scheme implementation principle:
Firstly, embodiment in the prior art, the mechanism of usually used rolling guide, such as schemes in the prior art
Shown in 1- Fig. 2,3 groups of supporting arms 2 are uniformly housed in 120 ° in guide body 1, deflector roll 3 is attached separately on supporting arm 2, and three groups are led
Roller 3 forms corresponding pass, and clamping guidance rolled piece enters milling train and rolled；For various sizes of rolled piece, need to adjust three groups
Deflector roll 3 pass adapts to, and adjustment process is that driving gear 5 is driven to rotate by regulating mechanism 4, and driving gear 5 drives center tooth
6 rotation of wheel, while 3 groups of adjustment gears 7 are driven, adjustment gear 7 is coupled with spline screw rod 8 by involute spline, spline screw rod 8
Design has rectangular thread, forms screw thread pair with rectangular nut 9, two-sided bulb 10 is pushed to move, supporting arm 2 is with supporting mandrel 11
Fulcrum rotation, realizes 3 pass adjustment of deflector roll；In adjustment process, spline screw rod 8 and adjustment gear 7 are involute spline cooperation, real
Now guiding and torque transmitting, in actual operation, because spline fitted area is big, frictional force is big, axis when spline screw rod 8 being caused to adjust
It has some setbacks to movement, regulating mechanism 4 can be used normally in manual adjustment, but adjust when automatically adjusting online
Mechanism 4 is set under torque, because of 8 frictional force reason of spline screw rod, regulating mechanism 4 is caused to be more than setting torque and have skidded and ask
Topic, needs to reset 4 torque of regulating mechanism, or shut down manually adjusted after can just return to normal production；So that subsequent
Rolling process cannot be gone on smoothly；
It in order to which the rolled piece to different-diameter rolls, needs to adjust three groups of deflector rolls 3 simultaneously, forms corresponding pass, pass through
Regulating mechanism 4 is adjusted to realize, but because adjusting machining accuracy, the difference of backlash for being driven each part, three groups of deflector rolls 3 is caused to adjust
In section, predeterminated position cannot be reached simultaneously, eccentric situation occur, as shown in Fig. 2, qualified pass cannot be formed, in actual motion,
Because three groups of deflector rolls 3 treat rolled piece clamping force unevenness, rolled piece rotary motion is caused, milling train is unable to the preset specifying part of rolling rolling stock
Position, causes rolled parts cross sectional shape and surface quality cannot be guaranteed；
