Description
Technical field
The invention belongs to ring throstle, be specifically related to a kind of ring throstle split roller device.
Technical background
At present, main drafting unit---" roller " on the domestic and international ring throstle, the nipple that adopts comprises guide pillar and screw thread two parts usually, and guide pillar works the effect of centering, and screw thread plays the connection effect.At the head and the tail two ends of every joint roller, the one end has guide hole and screw, and the other end has guide pillar and one section screw thread, and roller is paid by screw thread and is linked to be " whole joint roller " in twos, screws by screw thread pair and transmits the draw zone required torque.
Tradition roller manufacturing procedure is tediously long, procedure surplus every joint roller will pass through nearly 50.Workpiece return multiple clamping, must require the strict control of inter process form and position tolerance, not only increase difficulty of processing, and need to be equipped with all kinds of high precise equipments, manufacturing cost is increased considerably.Though follow the principle of " smart, thin, tight, real " in process all the time, the product precision is still undesirable.Circular runout after any two joint rollers connect surpasses 0.05mm, even has more than the 0.2mm.Analyze its reason, the structural design of traditional roller is unreasonable, is to cause that difficulty of processing is big, precision does not reach the principal element of spinning process requirement.Because adopt screw thread pair to connect, in machining screw, guide pillar, guide hole process, multiple operation joins, be difficult to guarantee centre of gyration unanimity between the three, and the foul in the screwed hole is difficult to clean up, and roller is easy to cause " other strength " after connecting to making in twos, and the circular runout majority is overproof.In addition, screw thread pair roller in twos is linked to be " whole saving ", and so as to transmitting moment of torsion, this moment of torsion transfer mode is very unreasonable, and not only precision is difficult to guarantee, and gives and install, debug and bring inconvenience.
Summary of the invention
Technical problem to be solved by this invention provides a kind of ring throstle split roller device, the split roller device is paid connection without screw thread, adopts T type ingot that the roller guide hole is connected with the split guide pillar, transmits moment of torsion and axial location by key, every joint roller can be dismantled separately, and is efficient and convenient.
Technical scheme of the present invention: a kind of ring throstle split roller device, it comprises first axle bumper 1, first radial ball bearing 2, a roller 3, screw 4, split guide pillar 5, roller bearing 6, T type key 7, middle roller 8, tail roller 9, tailstock centering guide pillar 10, adjusts packing ring 11, second radial ball bearing 12, location bearing lid 13, second axle bumper 14 and alignment pin 15; Roller 3 left ends are provided with first radial ball bearing 2 and first axle bumper 1, and are connected with the headstock travelling gear, and the right-hand member of a roller 3 is provided with guide hole, guide hole radially be provided with the opening keyway; Split guide pillar 5 is provided with roller bearing 6, and it is flat that split guide pillar 5 two ends are provided with symmetry; Middle roller 8 two ends are provided with guide hole, guide hole radially be provided with the opening keyway; Tail roller 9 two ends are provided with guide hole, and the left end guide hole is provided with the opening keyway; Tailstock centering guide pillar 10 is a multidiameter, and left end is the centering guide pillar, and right-hand member is provided with second radial ball bearing 12 and second axle bumper, 14, the second radial ball bearings 12 are provided with location bearing lid 13, and location bearing lid 13 is provided with alignment pin 15 and refuels screw; Be provided with between tail roller 9 and the tailstock centering guide pillar 10 and adjust packing ring 11; Split guide pillar 5 one ends are connected with a roller 3 guide holes, and the other end is connected with middle roller 8 guide holes, and tailstock centering guide pillar 10 left ends are connected with the guide hole of tail roller 9, and right-hand member is connected with second radial ball bearing 12; In the opening keyway of a roller 3 right-hand members He in the middle roller 8 openings at two ends keyways, be provided with T type key 7.With the two ends guide hole have the middle roller 8 of opening keyway align two ends have flat split guide pillar 5 to insert and half-twist after T type key 7 and split guide pillar 5 flat linked fastening by screw 4.Any two joint rollers connect the back circular runout less than 0.05mm.Be provided with the T profile of T type key 7 in the gap between roller bearing 6 and the middle roller 8.
The present invention compared with prior art has following beneficial effect: it is tediously long to adopt the split roller device can overcome traditional roller manufacturing procedure, and the manufacturing cost height obtains higher economic results in society.The split roller adopts T type key that the roller guide hole is connected combination with the split guide pillar, transmits moment of torsion by key, and axial location, and every joint roller can be dismantled separately, and is efficient and convenient.The split roller adopts guide hole and split guide pillar radial centering, and after any two joint rollers connections, its circular runout is smaller or equal to 0.05mm, no axial float.
