Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present invention and operation principle are described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, one suffers from one's own actions positive axis head clamping mechanism, and standard oil cylinder 4 is fixed on left fixed block 2, and is threaded with left tray 5, left tray 5 is arranged in the groove of left fixed block 2 to the part that the both sides being parallel to standard oil cylinder 4 extend, and slidingly contacts with left fixed block 2.Adjustment oil cylinder 12 is fixed on right fixed block 11, and is threaded with right bracket 10, and right bracket 10 is arranged in the groove of right fixed block 11 to the part that the both sides being parallel to adjustment oil cylinder 12 extend, and slidingly contacts with right fixed block 11.Standard oil cylinder 4, adjustment oil cylinder 12 are connected by rotating nut 17 respectively with between left tray 5, right bracket 10, and the fine-tuning best orientation position determining adjustment oil cylinder 12, eliminates the alignment error of clamping device.Be provided with supporting plate 6 between left tray 5 and the right bracket 10 two Hooks coupling universal coupling spindle noses 16 respectively and in genesis analysis, described supporting plate 6 is threaded with left tray 5 and right bracket 10 respectively.Supporting plate 6 is the arc surface that diameter is identical with the contact surface of Hooks coupling universal coupling spindle nose 16, supporting plate 6 is cambered surface with contact surface a and b of left tray 5, right bracket 10 along Hooks coupling universal coupling spindle nose 16 axis direction, so that working roll homalocephalus realizes the automatic capturing in horizontal and vertical direction by cambered surface a and cambered surface b when entering Hooks coupling universal coupling spindle nose 16.Supporting plate 6 is attached with elastomeric material with the contact surface c of left tray 5, right bracket 10, for when entering roller, the automatic capturing of universal shaft coupling spindle nose 16 provides activity space, utilizes its elasticity that Hooks coupling universal coupling spindle nose 16 can be made again to return to home position after going out roller simultaneously.
In the present invention, standard oil cylinder 4 stroke is provided with surplus, plays pressuring action, each correlated parts is more fitted, and eliminates gap, ensures to hold position tightly accurate; The cylinder diameter of adjustment oil cylinder 12 is greater than standard oil cylinder 4, stretches out rear position and no longer changes, play the role of positioning.
The part that left tray 5, right bracket 10 slide respectively in left fixed block 2, right fixed block 11 is provided with pressing plate 3, and pressing plate 3 is threaded with left fixed block 2, right fixed block 11 respectively.Oil cylinder pushing bracket moves, and bracket is slided in fixed block, and pressing plate 3 guarantees that the part that bracket slides in fixed block can not deviate from fixed block.
Pressing plate 3 is provided with slide plate 21 with the sliding contact surface of left fixed block 2, right fixed block 11 respectively, left fixed block 2 is provided with lubricating cup 20 with the upper and lower surface of right fixed block 11, described lubricating cup 20 is delivered to lubricating grease in the surperficial oil groove of slide plate 21 by inner oilhole, slide plate 21 surface is lubricated, ensures that bracket slides smoothly in fixed block.
Described left fixed block 2, right fixed block 11 are fixed with switch frame 19 respectively, switch frame 19 are separately installed with two proximity switches 1, the distance between homonymy two proximity switch 1 is the stroke that same side cylinder stretches out; Described left tray 5, right bracket 10 are fixed with sensor block 13 respectively, and sensor block 13 is with bracket action.When oil cylinder stretches and reaches the limit of position, by contactless electromagnetic induction, preferentially sense that Signal transmissions is gone out by the proximity switch 1 of metallics nearest in coverage, control the flexible of oil cylinder by hydraulic valve block.
During roll change, limited block 18 is respectively equipped with between the part of described left tray 5 beyond described groove and left fixed block 2, between the part of right bracket 10 beyond described groove and right fixed block 11, for limiting cylinder action, ensure that Hooks coupling universal coupling spindle nose 16 is held tightly all the time, cause spindle nose 16 to be deviate from from enclasp device with anti-misoperation and drop.After roll change completes, take out limited block 18, two oil cylinders are retracted.
Described clamping device is arranged on the transmission side of mill housing, and described left fixed block 2, right fixed block 11 limit it respectively by block 14 and move, and described block 14 welds with memorial archway, and described block 14 is at least each two around.Block 14 plays a part to eliminate fixed block screw gap, to guarantee that setting position is constant all the time.
Supporting plate 6 is provided with cushion pad 9 with the junction of left tray 5 and right bracket 10 respectively.Described cushion pad 9 can be rubber blanket, works the effect of flexibly connecting.
Described left tray 5 and right bracket 10 are equipped with the outside of supporting plate 6 coupling part respectively and adjust screw 7, and described adjustment screw 7 is arranged along Hooks coupling universal coupling spindle nose 16 vertical axis direction, and contacts with supporting plate 6.Adjustment screw 7 is compressed by screw on two lateral brackets or unclamps supporting plate 6, can the position of auxiliary adjustment everything shaft coupling spindle nose 16 on vertical axis direction, eliminates spindle nose nose and bowing phenomena.
During roll change, oil cylinder stretches out and Hooks coupling universal coupling spindle nose 16 held tightly by the supporting plate promoted on bracket, and corresponding proximity switch 1 sends signal, now Hooks coupling universal coupling akinesia, carries out roll change action; At the end of roll change, oil cylinder is retracted, and clamping device unclamps, and corresponding proximity switch 1 sends signal, and now Hooks coupling universal coupling can action, then enter duty.
Because the present invention utilizes the self-defence characteristic of supporting plate two cambered surfaces to realize the automatic capturing of Hooks coupling universal coupling spindle nose 16, ensure that working roll pushes smoothly and releases, effectively can eliminate position deviation when alignment error of the present invention and working roll enter roller, and then make operation roll change very convenient, not only greatly saved roll changing time and decreased rolling non-cutting time simultaneously, and the present invention has easy to operate and adjusts feature flexibly and effectively.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
