Description

TECHNICAL FIELD

[0001] The utility model relates to a centering mechanism, specifically to a centering mechanism with quick positioning. BACKGROUND

[0002] In order to facilitate the assembly of carbon block and prevent the filling material from falling into the electrolytic cell to affect the quality of primary aluminum, the filling material adhered to the surface of the carbon block must be cleaned before the carbon block is transferred to the next process, and the baking layer cleaned is recycled; because the recycling prices of carbon block and baking layer are different, and the recycling price of the base material is several times of the baking layer.

[0003] Each carbon block can weigh several tons, if manual cleaning is used, the labor intensity of workers is large, the production efficiency is low, and the working environment is seriously polluted, therefore, mechanical cleaning is usually used in a cleaning line.

[0004] In the prior art, before the carbon block is cleaned by using a machine, the uncleaned carbon block is hoisted to a feeding mechanism by using a crane, and the carbon block is cleaned after the position of the carbon block is centered with the cleaning mechanism on the cleaning line, therefore, each carbon block hoisted on the feeding mechanism needs to be centered, but the limiting mechanism in contact with the carbon block is usually provided with edges during the operation of the existing centering mechanism, when the edge on the limiting mechanism is in contact with the carbon block, the carbon block is easily damaged, thereby causing economic loss. UTILITY MODEL CONTENTS

[0008] Through the technical scheme, when the carbon block is hoisted on the rack, when the first linear driving assembly pushes the first pushing piece to move towards the carbon block, when the carbon block is pushed to the limiting block, the limiting block is the first roller, and at this time, the circumferential surface of the first roller is against the carbon block, thereby effectively reducing the probability of damage to the carbon block, thereby reducing economic losses.

[0010] Through the technical scheme, through the setting of the wedge-shaped support block, because the carbon block surface adheres to the roasting layer which is particularly rough, and in the process of aligning the carbon block, the wedge-shaped support block can avoid the roasting layer of the carbon block from being stuck in the hoisting station, thereby ensuring the alignment action of the carbon block.

[0011] Further, the first linear driving assembly comprises an oil cylinder, the oil cylinder is fixedly installed on the side vertical surface of the first pushing piece away from the first roller through a fixing seat, and the output shaft of the oil cylinder is fixedly connected with the first pushing piece.

[0012] Through the technical scheme, by arranging the first linear driving assembly on the side vertical surface away from the first roller, in the process of hoisting the carbon block and limiting the position of the carbon block, a large amount of dust will be generated, and at this time, the first pushing piece can block part of the dust, thereby reducing the dust entering the internal structure of the first linear driving assembly, thereby prolonging the service life of the device and reducing the maintenance cost.

[0013] Further, the two ends of the first pushing piece in the length direction are respectively provided with a strip-shaped notch, and each strip-shaped notch is arranged along the length direction of the first pushing piece.

[0021] Through the technical scheme, the movement track of the first pushing member can be limited through the cooperation of the linear slide rod and the plurality of sliding blocks, thereby ensuring accurate linear motion and providing high-precision control effect.

[0022] Further, each side vertical surface of each limiting plate near the length direction center of the first pushing member is provided with a plurality of second rollers, the plurality of second rollers on each limiting plate are sequentially arranged along the height direction of the limiting plate, and the central axis of each second roller is perpendicular to the corresponding limiting plate.

[0023] Through the technical scheme, the second roller can avoid the carbon block baking layer from being stuck on the hoisting station during the carbon block centering process, thereby ensuring the carbon block centering action.

[0024] Further, a reinforcing rib is arranged between each limiting plate and the corresponding connecting plate.

[0025] By the technical scheme, the stress concentration on the limiting plate and the connecting plate can be avoided by arranging the reinforcing rib, thereby reducing the deformation degree of the limiting plate and the connecting plate, and improving the stability after the limiting plate and the connecting plate are connected.

[0032] 6. By cooperating the linear sliding rod and the plurality of sliding blocks, the movement track of the first pushing piece can be limited, thereby ensuring accurate linear motion, thereby providing high-precision control effect.

[0033] 7. By arranging the second roller, because the baking layer attached to the surface of the carbon block is particularly rough, the second roller can avoid the baking layer of the carbon block from being stuck in the hoisting station during the centering of the carbon block, thereby ensuring the centering action of the carbon block.
