Detailed description of the invention
The exemplary embodiments that embodies feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various variations on different embodiment, it neither departs from the scope of the present invention, and explanation wherein and accompanying drawing be when the use that explain in itself, but not in order to limit the present invention.
As depicted in figs. 1 and 2, be provided with roll 11 on reeler, roll 11 is arranged on roll-box 10, and the spacing of roll 11 is L, and this spacing L realizes by the position of adjusting roll-box 10.Reeler of the present invention rolls roller distance adjusting device and comprises a hydraulic cylinder 2, two symmetrically arranged screw mandrels 61,62, screw 71,72 and plunger case 8.
The cylinder body of hydraulic cylinder 2 is fixedly mounted in frame 9, the hinged roll-box 10 of the piston rod of hydraulic cylinder 2.In the time strengthening spacing L, hydraulic cylinder 2 moves, and pulls roll-box 10 to regain, thereby spacing L is increased; In the time reducing spacing L, hydraulic cylinder 2 is servo-actuated.
Hydraulic motor 31,32 is all fixedly mounted in frame 9, hydraulic motor 31 worm speed reducer 41 that is in transmission connection, hydraulic motor 32 worm speed reducer 42 that is in transmission connection, worm speed reducer 41,42 is all fixedly mounted in frame 9, for reaching synchronization action object, conventionally by shaft coupling 5, two worm speed reducers 41,42 are coupled together.The be in transmission connection output shaft of worm speed reducer 41 of screw mandrel 61,62, the be in transmission connection output shaft of worm speed reducer 42 of screw mandrel 62, screw 71,72 is all fixedly mounted on the machine of reeler, on 9, screw mandrel 61 and screw 71 match, screw mandrel 62 and screw 72 match, and screw mandrel 61,62, under worm decelerating machine 41., 42 drives and under the mating reaction of screw 71,72, rotates flexible.
The end of screw mandrel 61,62 all fixedly mounts a plunger case 8, screw mandrel 61,62 connects roll-box 10 by plunger case 8, thereby (be mainly effect while stretching out rotating when flexible, when retraction, make actuator by hydraulic cylinder 2, screw mandrel 61,62 is made follower) drive roll-box 10 to move, thus adjust the spacing L of roll 11.The fine setting spacing of plunger case 8 is the stroke of plunger case 8, and as shown in fig. 1, the trip is l, and in the present embodiment, l is 5-10 millimeter.
As shown in Figure 3, plunger case 8 comprises cylinder body and plunger 82, and cylinder body comprises cylinder barrel 811 and gland 812, between cylinder barrel 811 and gland 812, interconnects by bolt 813, and cylinder barrel 811 connects roll-box 10.Plunger 82 one end slip caps are contained in cylinder body, and the other end is the end of connection wire rod 61 or 62 rotationally.Between plunger 82 and cylinder barrel 811, form plunger cavity 80, plunger 82 slides therein, and its stroke is 5mm, and plunger cavity 80 is communicated with oil circuit by passage 801, and passage 801 is arranged on cylinder barrel 811.Cylinder barrel 811 outer rims are square cylinder, be socketed on roll-box 10, and can not rotate between roll-box 10, for avoiding the relative cylinder barrel 811 of plunger 82 to rotate, the first alignment pin 821 is set between plunger 82 and cylinder barrel 811, cylinder barrel 811 is processed with pin-and-hole, is also processed with corresponding pin-and-hole on plunger 82, and the first alignment pin 821 is slidably arranged in this two pin-and-hole.
End fixing suit one installation sleeve 63 of screw mandrel 61,62, is provided with first step in the outer rim of installation sleeve 63.The exposed junction of plunger 62 is fixedly connected with a platen 83 by bolt 831, on platen 83, is provided with second step, and first step coordinates the end that makes plunger 82 axially be pressed against screw mandrel 61,62 along screw mandrel 61,62 with second step.Between plunger 82 and screw mandrel 61,62 ends, be also installed with and determined piece 84 and motion block 85, motion block 85 connects the end that is arranged on screw mandrel 61,62, determine piece 84 and connect the mounting structure of plunger 82(the second alignment pin 87 and anti-rotation principle with the first alignment pin 821 by the second alignment pin 87, also be non-central being arranged on two objects that are oppositely arranged, thereby this object of anti-rotation relatively rotate).Determining piece 84 is pressed against between plunger 82 and motion block 85, determining piece 84 can rotate relative to motion block 85, therefore determines to be provided with lubrication gap 88 between piece 84 and motion block 85, and lubricating oil is wherein set, this lubrication gap 88 is communicated with a lubrication channel 86 by determining 85 contact gaps of piece 84 and motion block, to facilitate fuel feeding.On one end of motion block 85 connection wire rods 61,62, be provided with boss 851, the cross section of this boss 851 is square, thereby motion block 85 can be rotated together with screw mandrel 61,62.
Plunger case 8 structures of the present invention are described above, do not rotate together with screw mandrel 61,62, but link together with roll 10, by the fine setting of plunger 82, drive cylinder barrel 811 to drive roll-box 10, roll 11 to finely tune, this fine setting spacing is 5-10 millimeter, is certainly also not limited to these data, determines according to actual needs.As shown in Figure 4, for preventing that cylinder barrel 811 from rotating, cylinder barrel 811 is designed to square, bottom is spheric structure, in roll-box 10 relevant positions, the hole coordinating with cylinder barrel 811 profiles is set, and copper pad 89 is set in hole, between cylinder barrel 811 and copper pad 89, face contacts, and realizes side pressure and enter to adjust the function of roll spacing.
Beneficial effect of the present invention is, the present invention compared with prior art, in the present invention, at the end of screw mandrel 61,62 fixed installation plunger case 8, connect roll-box 10 by plunger case 8, only need plunger 82 in drive post plug cylinder 8, can realize the fine setting of breaker roll 11 spacing, without dismounting refitting, can adjust online simple in structure, convenient and reliable operation, efficiency is high, is suitable for and promotes the use of.
