Abstract

The utility model relates to a centering mechanism for ceramic edge finishing machines, which belongs to the auxiliary device of the processing machine. The centering mechanism for ceramic edge finishing machines is composed of a brick pushing guide shaft, a sliding support, a horizontal air cylinder, a photoelectric tube, etc. The sliding support is parallelly fixed with two optical shafts which are connected with sliding blocks through sliding; the sliding blocks can form a group of symmetrical transmission mechanisms of the sliding blocks of the rocking rods through the respective connection with a connecting rod, a rotating disk, and a centering air cylinder; the portion of the sliding blocks is provided with a centering roller which can form a three dimensional coordinate with a positioning fork which can move up and down on the sliding support. The utility model has the advantages of accurate positioning, no damage to edges and faces, and strong adaptability to different work pieces, and the processed work pieces have parallel opposite sides and vertical adjacent edges.

Description

Pottery edge polisher centering body

The utility model relates to the technical field of grinding auxiliary equipment, the centering positioner before particularly a kind of the processing.

The grinding detent mechanism of existing ceramic edge polisher adopts fixing guide rail and movable pressure roller structure, and line slideway is fixed in feed belt one side, and parallel with feed belt, and workpiece is during with belt movement, and workpiece wherein slides on guide rail on one side; And pinch roller and power bistrique are housed on feed belt opposite side guide rail opposite.During edging, one side be benchmark with what slide on the guide rail, by the pinch roller location, the power bistrique processes workpiece earlier on one side, on one side and then be its standard with this, process opposite side, change 90 ° and reprocess adjacent sides.Since earlier with the limit of undressed mistake as benchmark, workpiece slides not steady in guide rail, two in addition belts transmit and have speed difference, mismachining tolerance, are offset, rotate when causing the work transmission again easily, make first limit that processes fluctuating be arranged, out-of-flatness; Be that the opposite side that benchmark processes just exists bigger parallelism error with this limit again, sometimes even inhomogeneous, make first limit and the guide rail collision of having processed, cause and collapse the limit, collapse the angle because of pinch roller pressure.Therefore the adjacent side of workpiece also can't be processed vertically, has influenced the quality of product.

The purpose of this utility model is for overcoming the deficiencies in the prior art part, a kind of accurate positioning is provided, can guarantee that the center line of workpiece overlaps with the axis of processing equipment, thereby makes the workpiece processing back ceramic edge polisher centering body that opposite side is parallel, adjacent side is vertical.

The purpose of this utility model is achieved by the following technical solution: ceramic edge polisher centering body, include push away the brick axis of guide, with push away balladeur train that the brick axis of guide is slidingly matched, promote horizontal air cylinder and photoelectric tube that sends the positioning control signal and support thereof that balladeur train moves vertically, special feature is that secured in parallel has two optical axises on the balladeur train, slidely connect slide block on the optical axis, slide block is slidingly connected into the rocker slider transmission mechanism of one group of symmetry respectively with two connecting rods, rotating disk, centering cylinder, the centering roller is equipped with in the end of two slide blocks; Location moving up and down fork also is housed on the balladeur train, constitutes the three-dimensional coordinate location with the centering roller.

Because two rocker slider transmission mechanisms are symmetrical, two centering rollers are in same horizontal plane move toward one another separately, as long as machining center dead in line with symmetrical centre between the centering roller and edge polisher, workpiece initial position irregularity how no matter, all can be by in the middle of two centering rollers just push away and be sandwiched in, the center line that makes workpiece automatically with the centering roller between symmetrical centre overlaps, and then fall to locate and pitch, make workpiece three-dimensional localization on balladeur train, centering before sending into the edge polisher grinding.Such structure has the following advantages:

1, do centering with the natural geometry center of workpiece, centralized positioning is accurate, and it is little to add the error that produces man-hour;

2, do not damage manufactured limit face;

3, the adaptability to workpiece is strong, can adapt to the workpiece location of different size specification, unlike material.

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to partial view;

Fig. 3 is that the B of Fig. 1 is to partial view.

With reference to Fig. 1, the main body of present embodiment by fixing push away the brick axis of guide 1, with push away balladeur train 3 that the brick axis of guide is slidingly matched, horizontal air cylinder 4, photoelectric tube 5 and be configured to, behind the oriented signal of photoelectric tube 5 induction workpiece, horizontal air cylinder 4 promotes balladeur train 3 and axially moves horizontally, and workpiece is sent into edge polisher processing.

See figures.1.and.2, balladeur train 3 secured in parallel in vertical direction has two optical axises 9, optical axis 9 two ends slidely connect two sliding shoes 11, between two slide blocks 11 rotating disk 8 is arranged, rotating disk 8 and each slide block 11 be slide hinged connecting rod 6, rotating disk 8 is then hinged with the centering cylinder 2 that is fixed on the balladeur train 11, and constituting with centering cylinder 2 is the slider-rocker mechanism of two symmetries of power source.When centering cylinder 2 promotion rotating disks 8 turn clockwise, about two connecting rods 6 driven, and the slide block 11 at two ends furthered in opposite directions along optical axis 9, the two centering rollers 7 that are loaded on slide block 11 ends are also done equidistance motion in opposite directions (showing as solid arrow among Fig. 2) thereupon, until workpiece being sandwiched in the middle of the two centering rollers.When centering cylinder 2 promotes rotating disks 8 and is rotated counterclockwise, about two connecting rods 6 slide block 11 at two ends is pushed open to both sides simultaneously, make centering roller 7 opposing equidistant moving, so that next workpiece is done centering location (showing as dotted arrow among Fig. 2).

With reference to Fig. 3, after centering roller 7 is clamped workpiece centering, because location fork 10 is slidingly connected with balladeur train 3 in vertical direction by location fork shaft 13, so, the vertical cylinder 12 that is fixed on the balladeur train 3 will push away downwards with location, fork 10 edge, the rigidly connected location of one end fork shaft 13, form workpiece location benchmark vertically upward, and under the drive of balladeur train 3, workpiece pushed edge polisher processing.

Certainly, except that the cylinder that the foregoing description is described, the utility model also can adopt other equivalent power source, realizes the accurate centering location to workpiece.
