Description
Technical field
The invention belongs to the last roll assembly of welding rolls milling train, particularly a kind of fast roll changing device of welding rolls milling train top roll.
Background technology
At present, in the welding rolls milling train on roll assembly, its structure comprises support, elevating mechanism, guide rail, longitudinal slide; Roller frame, roll shaft, pressing plate and top roll, at support top dress elevating mechanism, drive by elevating mechanism, along the longitudinal slide of the upper and lower slip of guide rail; On the longitudinal slide lateral surface, connect the roller frame; Adorn roll shaft on the roller frame, the top roll of suit roller two ends buried bearing on roll shaft, and on the roll shaft section at top roll two ends, through pressing plate top roll is fixed.Its shortcoming and defect part is:
1, the size of roll body is big because at the roller two ends buried bearing, it is big to cause the size that goes up roll body.
2, because the structure of roller frame is very unreasonable, cause poor rigidity.
3, the installation accuracy of top roll is poor, and the reappearance of precision is bad.
4, when roll change, not only long but also effort of time.
Summary of the invention
The present invention is intended to the shortcoming and defect part that in above-mentioned technology, exists; And providing not only reasonable in design, compact conformation had both improved installation accuracy; Reduced the size of roll body again; And having good rigidly, roll change is convenient, the time saving and energy saving fast roll changing device that has reached a kind of very easily welding rolls milling train of use top roll.
The objective of the invention is to adopt following technical scheme to realize: the fast roll changing device of described welding rolls milling train top roll; Comprise that frame, elevating mechanism drive the longitudinal slide of upper and lower slip, top roll; It is characterized in that: installing is by roller seat drive power source, that laterally slide on the lateral surface of longitudinal slide; Cover cap is by the frame that pushes away of pneumatic or the upper and lower motion of hydraulic-driven, planer-type in roller seat both sides and top outside; In pushing away the biside plate face of frame bottom, be symmetrily processed with two grooves, described each groove is from outer upper lower tilt to the inside, and each groove and last roller diameter constitute horizontal sextant angle β; The middle part of described roller seat has uncovered top roll chamber, bottom; In the both ends of the surface in top roll chamber, be arranged with the diaxon bearing; In the diaxon bearing, roll shaft is housed, top roll is housed, connect end cap in the outside of each bearing block at the middle part of roll shaft; Be provided with gib head at end cap and the end cap side that pushes away between the frame, the travel mechanism of two hooks of symmetry installing on two gib heads.
Described each horizontal sextant angle β is 20 °～90 °.
The power source of the roller seat that described driving is laterally slided is manual, electronic, hydraulic pressure or pneumatic.
The cross section of described gib head or square or circular.
The travel mechanism of described each hook is made up of hook plate and axle, and the bottom clasp joint of hook plate is on gib head, and the top of hook plate is connected the axle that slides in the groove.
Principle of the present invention is set forth in down with the operation branch:
Because installing is by roller seat drive power source, that laterally slide on the lateral surface of in the present invention longitudinal slide, push away frame and symmetry is installed two hooks on two gib heads travel mechanism by pneumatic or the upper and lower motion of hydraulic-driven, planer-type at roller seat both sides and outside, top cover cap.Just make the overall structure among the present invention become flexible structure, obtain between each parts each other organically coordinating, be convenient to install, regulate and precision of the present invention is greatly improved and makes roll change convenient thereby make.
The comprehensive above technical scheme of being taked realizes the object of the invention.
Compared with prior art, the present invention is not only reasonable in design, and compact conformation had both improved installation accuracy, had reduced the size of roll body again, and had good rigidly, and roll change is convenient, and time saving and energy saving having reached used advantages such as very convenient.
