Description
Technical Field
The invention relates to the field of mechanical equipment, in particular to a roll clearance precision adjusting mechanism for adjusting the distance between two rollers.
Background
In mechanical equipment, the screw rotates to pull the equipment components connected with the nut to move through the rotation of the screw in the nut, which is a common technical means for adjusting the distance between the equipment components, for example, in the roll gap adjustment of a flour mill, the distance between two rolls is adjusted through the rotation of a pitch adjusting screw (i.e., the screw). In the prior art, a screw is usually locked by a locking nut or locked by a pneumatic telescopic cylinder pushing against the screw, but the problem of inconvenient operation when the locking nut is used for locking and the problem of pressure air source requirement when the pneumatic telescopic cylinder pushing against the screw is used for locking are solved.
Disclosure of Invention
The invention provides a roll clearance precision adjusting mechanism which is convenient to operate and does not need an air source, and aims to solve the problems in the prior art in the screw locking process during roll clearance adjustment.
The invention relates to a roll clearance precision adjusting mechanism which comprises a lead screw, a lead screw seat, a hand wheel, a sliding sleeve, a locking rod and a sliding block, wherein the lead screw seat is arranged on the lead screw seat; the screw rod is arranged in a screw rod cavity of the screw rod seat, and a through hole for installing the locking rod is formed in the screw rod seat; a plurality of axial locking grooves are uniformly formed in the outer circumference of the screw rod at the position corresponding to the locking rod, and the lower end of the locking rod can be embedded with the locking grooves in the screw rod; the hand wheel is fixedly connected with the sliding sleeve; the sliding sleeve is sleeved with the right end of the lead screw through the axial sliding chute, and the sliding sleeve can axially slide on the lead screw but cannot rotate in the circumferential direction of the lead screw; the sliding block is fixedly connected with the connecting plate, the connecting plate is sleeved through the plate hole and is axially clamped on the sliding sleeve, and the sliding sleeve can rotate in the plate hole of the connecting plate but cannot axially slide in the plate hole; the slider upper surface is provided with domatic, and the check lock lever upper end is provided with the lift bar, and the slider slides and withstands the lift bar and can promote the check lock lever.
Preferably, the lifting rod is provided with a roller.
Preferably, a guide sleeve is installed in the through hole, and the locking rod is arranged in the guide sleeve with a spring in the installation, so that deflection of the locking rod is reduced.
Preferably, the lower surface of the sliding block is arranged in a sliding rail arranged on the screw rod seat, so that the direction deviation of the sliding block during sliding is reduced.
According to the rolling distance precision adjusting mechanism, when a lead screw is locked, the lower end of a locking rod is in an embedded state with a locking groove in the lead screw; when the distance between the parts is required to be adjusted, the movable sleeve axially slides on the screw rod through the hand wheel to drive the sliding block to slide, the slope on the upper surface of the sliding block lifts the locking rod, the lower end of the locking rod is separated from the locking groove, and then the hand wheel is rotated to rotate the screw rod to finish the distance adjustment; then the movable sleeve is returned to the original position through the hand wheel, the locking rod falls, the lower end of the locking rod and the locking groove on the screw rod are in an embedded state again, and the screw rod is locked. Therefore, the roll clearance precision adjusting mechanism can conveniently complete position locking after roll clearance precision adjustment under the condition of not additionally arranging an air source, and is low in cost, stable and reliable.
