The technical solution of the utility model is, described multi-line cutting machine home roll handler has the U-shaped frame, its design feature is, screw mandrel is equipped with through plain thrust bearing in the middle part of described U type frame, the front end of this screw mandrel between two arms of described U type frame and this screw mandrel front end ring flange is housed; Locking nut is equipped with in the screw mandrel rear end, between the plain thrust bearing in this locking nut and the U type frame bearing locknut is housed; Two arm front ends of described U type frame respectively have the semicircular opening groove that can embed the soket head cap screw nut, and semicircular opening groove upper end is for there to be the translot that draws stress surface and push away stress surface, and the opening direction of these two semicircular opening grooves on two forearms is opposite.

Below the utility model made further specify.

Referring to Fig. 4, the operation principle and the using method of the utility model device are, two soket head cap screw nuts 16 of equipment box front portion are embedded respectively (wherein screw is arranged in the semicircular opening groove 7 of Fig. 1 or Fig. 2 in the corresponding semicircular opening groove 7 of described U type frame two arm front ends, in the translot 8 of nut in Fig. 1 and drawing stress surface 9 and pushing away between the stress surface 10), ring flange 2 is close to attachment screw (three screws) 17 with main shaft driven subassembly 14 end faces and is connected; Ring flange 2 centers are threaded into screw mandrel 4, and screw mandrel 4 is formed revolute pair with plain thrust bearing 6, bearing locknut 3 and locking nut 5, U-shaped frame 1.The utility model by the anterior screw nut of equipment box outside and inner edge respectively with the drawing stress surface 9 and push away stress surface 10 and contact of U-shaped frame forearm end semicircular opening groove, when screw mandrel 4 forward and reverse, draw stress surface 9 and to push away stress surface 10 stressed respectively, but 14 pairs of home rolls 13 of ring flange 2 push-and-pull main shaft driven subassemblies mount and dismount; Outside and draw stress surface 9 and push away between the stress surface 10 and leave certain interval in the nut, loosening screw mandrel 4 can easily break away from and draws stress surface 9 and push away stress surface 10 and contact, convenient main this roller handler withdraws from, can control the dynamics and the speed of push-and-pull main shaft driven subassembly 14 by moment impact wrench rotary screw 4, guarantee installation accuracy, improve the home roll efficiency of loading.

As known from the above, the utility model is a kind of multi-line cutting machine home roll handler, and it can effectively shorten multi-line cutting machine home roll installation time, guarantees assembly precision, enhances productivity.

The specific embodiment

As shown in Figure 1 to Figure 3, described multi-line cutting machine home roll handler has U-shaped frame 1, and screw mandrel 4 is equipped with through plain thrust bearing 6 in the middle part of described U type frame 1, the front end of this screw mandrel 4 between two arms of described U type frame 1 and these screw mandrel 4 front ends ring flange 2 is housed; Locking nut 5 is equipped with in screw mandrel 4 rear ends, between the plain thrust bearing 6 in this locking nut 5 and the U type frame 1 bearing locknut 3 is housed; Two arm front ends of described U type frame 1 respectively have the semicircular opening groove 7 that can embed the soket head cap screw nut, and semicircular opening groove 7 upper ends are that the translot 8 that draws stress surface 9 and push away stress surface 10 is arranged, and the opening direction of these two semicircular opening grooves 7 on two forearms is opposite.

As Fig. 4, motor drives main shaft drives assembly 12 transfer motion powers by drive pulley 11 and gives home roll 13, and home roll 13 is locked by screw rod by main shaft drives assembly 12 and main shaft driven subassembly 14, conical surface location, pin on-slip, main shaft driven subassembly 14 can move in equipment is cut into slices case cavity arm axle hole; The effect of this home roll handler is that push-and-pull main shaft driven subassembly 14 moves axially, and home roll 13 is loaded and unloaded.

As Fig. 4, dismounting home roll operation: when screw mandrel 4 turns clockwise, U-shaped frame 1 end draws stress surface 9 to contact the outside of the soket head cap screw nut 16 that links with casing, driving ring flange 2 draws main shaft driven subassembly 14 outwards to break away from home roll 13, when the gap greater than the interlock of conical surface two ends apart from the time, home roll 13 is extensible.

Assembling home roll operation: when screw mandrel 4 is rotated counterclockwise, U-shaped frame 1 end pushes away the link inner edge of soket head cap screw nut 16 of stress surface 10 contact and casing, drive ring flange 2 promotion main shaft driven subassemblies 14 compress home roll 13 and move inward, satisfy and go on foot in the conical surface embedding home roll 13 that makes the both sides assembly, until home roll 13 is compressed, with bolt that home roll 13 is fastening at last.

Can control the dynamics and the speed of push-and-pull main shaft driven subassembly 14 by moment impact wrench rotary screw 4, guarantee installation accuracy.

Certain interval is left with drawing stress surface 9 and push away stress surface 10 in the outside in the soket head cap screw nut 16, and loosening screw mandrel 4 can break away from nut and draw stress surface 9 and push away stress surface 10 and contact, and makes things convenient for home roll 13 handlers to withdraw from.
