Abstract

The utility model relates to a precision centering device which comprises two parallel guide rails mounted at the upper end of a frame. A pair of centering plates are sleeved at the left ends and the right ends of the two guide rails, a rotation gear is arranged between the two guide rails and positioned between the centering plates, two rack shafts are arranged in the front and at the back of the rotation gear respectively and are parallel to the guide rails, one end of one rack shaft is connected with one centering plate, and the other end of the other rack shaft is connected with the other centering plate. The precision centering device is simple in structure, the rotation gear drives rotation racks to drive the centering plates to synchronously and relatively move, so that the centering plates are centered, precision reaches 0.5mm, plates between the centering plates can be positioned on a center line of a conveying roller, shape uniformity of the stacked plates is ensured, and the stacked plates are not crooked and not easily collapsed.

Description

Precise centering device
Technical field
The utility model relates to precise centering device.
Background technology
Plate shearing machine is mainly used in metal processing, it applies shearing force by the sheet metal to different-thickness, make sheet material carry out division processing according to required size, in the process that sheet material after cutting apart is well carried on conveying roller, the crooked center line that departs from conveying roller in sheet material meeting left and right, after every block of sheet material is stacked upon together, it is uneven that appearance seems, stacking easily collapses to certain altitude, has potential safety hazard.
Utility model content
For above-mentioned defect, the purpose of this utility model is to provide precise centering device, can make sheet material in conveying roller course of conveying, at certain position, carries out position adjustment, makes sheet material not crooked.
The technical scheme that the utility model adopts is for this reason:
Comprise two parallel guided ways that are arranged on frame upper end, on two guided ways, two ends, left and right cover has a pair of centering plate, in the middle of two guided ways, be provided with single-revolution gear, and be positioned in the middle of a pair of centering plate, before and after described swiveling gear, be respectively equipped with a toothed rack axle parallel with guided way, wherein a toothed rack axle one end is connected with a centering plate, and the other end of another toothed rack axle is connected with another centering plate.
Described swiveling gear below is provided with holder and is arranged in frame, and holder lower end is provided with single-revolution cylinder, and the output shaft of rotary cylinder is arranged in the bearing block on holder by bearing, and swiveling gear is socketed on output shaft.
The rear and front end, inner side of described centering plate is provided with directive wheel.
The utility model has the advantages that:
The utility model is simple in structure, returns gear driven passback tooth bar drive the synchronous relative motion of centering plate by employing, realizes centering plate and carries out centering, and precision reaches 0.5mm; Make the sheet material between centering plate on the center line of conveying roller, guarantee the profile regularity that stacking gets up, can be not crooked, be not easy to collapse.
Accompanying drawing explanation
Fig. 1, Fig. 2 are structural representations of the present utility model.
Fig. 3 is the cutaway view of A-A in Fig. 2.
In figure, 1 is frame, the 2nd, guided way, the 3rd, centering plate, the 4th, swiveling gear, the 5th, rack shaft, the 6th, holder, the 7th, rotary cylinder, the 8th, output shaft, the 9th, bearing, the 10th, bearing block, the 11st, directive wheel.
The specific embodiment
