The specific embodiment
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, a kind ofly suffer from one's own actions positive axis head clamping mechanism, standard oil cylinder 4 is fixed on left fixed block 2, and is threaded with left tray 5, the part that left tray 5 extends to the both sides that are parallel to standard oil cylinder 4 is arranged in the groove of left fixed block 2, and with left fixed block 2 sliding-contacts.Adjust oil cylinder 12 and be fixed on right fixed block 11, and be threaded with right carriage 10, right carriage 10 is arranged in the groove of right fixed block 11 to the part that is parallel to the both sides extension of adjusting oil cylinder 12, and with right fixed block 11 sliding-contacts.Standard oil cylinder 4, adjustment oil cylinder 12 are connected by rotating nut 17 respectively with between left tray 5, right carriage 10, the best orientation position of fine-tuning definite adjustment oil cylinder 12, the alignment error of elimination clamping device.Respectively and be between two Hooks coupling universal coupling spindle noses 16 of vertical distribution and be provided with supporting plate 6, described supporting plate 6 is threaded with left tray 5 and right carriage 10 respectively for left tray 5 and right carriage 10.Supporting plate 6 is the arc surface that diameter is identical with the contact-making surface of Hooks coupling universal coupling spindle nose 16, supporting plate 6 is cambered surface with contact-making surface a and the b of left tray 5, right carriage 10 along Hooks coupling universal coupling spindle nose 16 axis directions, so that the working roll homalocephalus is realized the automatic capturing of 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-making surface c of left tray 5, right carriage 10, and the automatic capturing of universal shaft coupling spindle nose 16 provides activity space when advancing roller, utilizes its elasticity can make again Hooks coupling universal coupling spindle nose 16 return to home position after going out simultaneously roller.
In the present invention, standard oil cylinder 4 strokes are provided with surplus, play pressuring action, and each correlated parts is more fitted, and eliminate gap, guarantee to hold position tightly accurate; The cylinder diameter of adjusting oil cylinder 12 is greater than standard oil cylinder 4, stretches out rear position and no longer changes, and plays the role of positioning.
On left tray 5, right carriage 10 slide respectively in left fixed block 2, right fixed block 11 part, be provided with pressing plate 3, pressing plate 3 is threaded with left fixed block 2, right fixed block 11 respectively.The oil cylinder pushing carriage moves, and makes carriage slide in fixed block, and pressing plate 3 guarantees that carriage slides in fixed block part 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 surfaces are lubricated, guarantee that carriage slides smoothly in fixed block.
On described left fixed block 2, right fixed block 11, be fixed with respectively switch frame 19, on switch frame 19, be separately installed with two approach switchs 1, the stroke of distance for stretching out with side cylinder between homonymy two approach switchs 1; On described left tray 5, right carriage 10, be fixed with respectively sensor block 13, sensor block 13 moves with carriage.Oil cylinder stretches while reaching the limit of position, and by contactless electromagnetic induction, the approach switch 1 of preferentially sensing metallics nearest in coverage transfers out signal, controls the flexible of oil cylinder by hydraulic valve block.
During roll change, between the part and left fixed block 2 of described left tray 5 beyond the described groove, right carriage 10 beyond described groove part and right fixed block 11 between be respectively equipped with limited block 18, for limiting cylinder action, guarantee that Hooks coupling universal coupling spindle nose 16 is held tightly all the time, cause spindle nose 16 to drop from enclasp device, deviating from anti-misoperation.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 by block 14 respectively and move, described block 14 and memorial archway welding, and described block 14 is at least each two of left and right.Block 14 plays a part to eliminate fixed block screw gap, constant all the time to guarantee setting position.
Supporting plate 6 is provided with cushion pad 9 with the junction of left tray 5 and right carriage 10 respectively.Described cushion pad 9 can be rubber blanket, works the effect of flexibly connecting.
Described left tray 5 and right carriage 10 are equipped with and adjust screw 7 with the outside of supporting plate 6 coupling parts respectively, and described adjustment screw 7 arranges along Hooks coupling universal coupling spindle nose 16 vertical axis directions, and contacts with supporting plate 6.Adjust screw 7 and compress or unclamp supporting plate 6 by the screw on two lateral brackets, but spindle nose nose and bowing phenomena are eliminated in the position of auxiliary adjustment everything shaft coupling spindle nose 16 on the vertical axis direction.
During roll change, oil cylinder stretches out and the supporting plate that promotes on carriage is held Hooks coupling universal coupling spindle nose 16 tightly, and corresponding approach switch 1 sends signal, and now Hooks coupling universal coupling akinesia, carry out the roll change action; When roll change finished, oil cylinder was retracted, and clamping device unclamps, and corresponding approach switch 1 sends signal, and now Hooks coupling universal coupling can move, and enters duty.
Because utilizing the self-defence characteristic of two cambered surfaces of supporting plate, the present invention realizes the automatic capturing of Hooks coupling universal coupling spindle nose 16, guarantee that working roll pushes smoothly and releases, position deviation in the time of can effectively eliminating alignment error of the present invention and working roll and advance roller, and then it is very convenient to make to operate roll change, not only greatly saved roll changing time and also reduced simultaneously rolling non-cutting time, and the present invention has easy to operate and adjusts characteristics flexibly and effectively.
The parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
