Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a lifting structure of a leveling machine. Background Art

[0002] The leveling machine is a device used to correct the flatness of steel plates. Its working principle is that the motor drives the upper and lower leveling rollers that are relatively set to rotate at the same time. The upper and lower leveling rollers are used to repeatedly twist and bend the steel plate to eliminate the internal stress of the steel plate, thereby achieving the effect of leveling the steel plate.

[0003] The gap between the upper and lower leveling rollers of the existing leveling machine cannot be adjusted, so that the leveling machine can only be used for steel plates of one thickness specification; it cannot be used for steel plates of different thickness specifications, thus resulting in the problem of poor applicability. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a lifting structure for a leveling machine.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A lifting structure of a leveling machine, comprising a support assembly arranged between an upper seat and a base, wherein the support assembly supports the upper seat above the base; a lifting cylinder for driving the upper seat to move up and down is fixed on the upper seat, and the lower end of the output shaft of the lifting cylinder passes through the upper seat and is fixed on the base;

[0007] The support assembly includes a lower support sleeve and an upper support sleeve both sleeved on the output shaft, and a driving motor for driving the lower support sleeve to rotate, the lower end of the upper support sleeve is threadedly matched with the lower support sleeve, and the inner side wall of the upper end thereof is provided with a vertical guide groove, and the vertical guide groove is matched with the vertical guide piece on the outer side wall of the output shaft;

[0008] The driving motor drives the lower supporting sleeve to drive the upper supporting sleeve to move vertically, so that the upper end of the upper supporting sleeve is separated from or abutted against the lower end surface of the upper seat.

[0009] The utility model is further configured that: a transmission gear is arranged on the outer side wall of the lower end portion of the lower supporting sleeve, and the driving gear on the output end of the driving motor drives the transmission gear to rotate through a belt, thereby driving the lower supporting sleeve to rotate.

[0010] The utility model is further provided that: an outer side wall of the output shaft is provided with an installation groove for installing a vertical guide member.

[0011] The utility model has the following beneficial effects: when the upper seat needs to be lifted to expand the gap between the upper leveling roller and the lower leveling roller, it is only necessary to first drive the upper seat upward by the lifting cylinder, and then drive the lower support sleeve to rotate by the driving motor. The upper support sleeve moves vertically upward under the guidance of the vertical guide member, and the upper end of the upper support sleeve abuts against the lower end surface of the upper seat to support the upper seat.

[0012] When the upper seat needs to be lowered to reduce the gap between the upper leveling roller and the lower leveling roller, it is only necessary to first reversely rotate the driving motor to drive the lower support sleeve to reversely rotate, and the upper support sleeve moves vertically downward under the guidance of the vertical guide member, so that the upper end of the upper support sleeve is first separated from the lower end surface of the upper seat; then the upper seat is driven downward by the lifting cylinder, and the lower end surface of the upper seat is again against the upper support sleeve;

[0013] The upper seat of the leveling machine can be automatically adjusted relative to the base, and the gap between the upper leveling roller and the lower leveling roller can be automatically and quickly adjusted; thus, the leveling machine can be used for leveling processing of steel plates of different specifications at the same time.
