Description
Technical field
The present invention relates to a kind of centralising device, be specifically related to the novel centralising device on a kind of Ceramic Tiles edge polisher.
Background technology
All be provided with centralising device on the existing Ceramic Tiles edge polisher, described centralising device is installed on the edge polisher front end, is to guarantee by mill ceramic tile center line and the consistent device of Ceramic Tiles edge polisher center line.
Fig. 1 to 3 is depicted as wherein a kind of version of existing centralising device, it comprises frame 7, cylinder 8 and left and right crossbeam (1,2), left side crossbeam 1 is equipped with left loose piece 11 by guide shaft 6, on the loose piece 11 of a left side two left centering pinch rollers 12 are installed, right crossbeam 2 is equipped with right loose piece 21 by guide shaft 6, on the right loose piece 11 two right centering pinch rollers 22 are installed, cylinder rod 81 is connected in short rack shaft 91, and short rack shaft 91 connects right loose piece 21 by lock-screw 5; Long rack shaft 92 connects left loose piece 11 by lock-screw 5, sets up power by gear 93 between short rack shaft 91 and the long rack shaft 92 and is connected.When ceramic tile by the time, cylinder rod 81 ejects, short rack shaft 91 drive right live 21 along guide shaft 6 to left movement; Short simultaneously rack shaft 91 makes gear 93 rotations, driving long rack shaft 92 moves right, the left loose piece 11 that is connected in long rack shaft 92 moves right along guide shaft 6, left and right sides loose piece (11,21) move distance equates that the direction of motion is opposite, left and right sides centering pinch roller (12,22) from about two directions press to ceramic tile, thereby reach the purpose of ceramic tile centering.During work, cylinder 8 active force P transfer ceramic tile to the reaction force F of pinch roller are acted on the left and right sides loose piece (11,21), and are delivered to gear 93 by short rack shaft 91 and long rack shaft 92 respectively, pass in frame 7 by gear 93, left and right sides crossbeam (1,2) thus do not stress and guarantee the centering effect.But this structure is adjusted difficulty when changing tile specification, see Fig. 3: if former ceramic tile width is 450mm, change mill 300mm now, at this moment need left crossbeam 1 and right crossbeam 2 are closed up toward the centre.Because gear 93 is loaded on frame 7, it is inactive when crossbeam closes up, thereby short rack shaft 91 is all inactive with long rack shaft 92, this just need unclamp lock-screw 5 makes it and left and right sides loose piece (11,21) throw off, when left crossbeam 1 and right crossbeam 2 reach assigned address, the position of adjusting left and right sides loose piece (11,21) again makes its center consistent with two crossbeam centers, and then locks with lock-screw 5, it is bigger to adjust the loose piece difficulty, need the two centering pinch roller lines of centres on the loose piece are parallel with the edge polisher center line, left and right sides loose piece (11,21) is equated to edge polisher centering distance between center line, adjustment process is more time-consuming, influences manufacturing schedule.
In order to overcome this defective, another kind of centralising device appears again, and its structure is shown in 4 to 6, and its structural change is for to have moved on to cylinder 8 on the left crossbeam.When ceramic tile by the time, cylinder rod 81 ejects, left loose piece 11 moves right along guide shaft 6, and drives long rack shaft 92 and move right, and makes gear 93 rotations, thereby makes short rack shaft 91 to left movement, the right loose piece 21 of short rack shaft 91 drives along guide shaft 6 to left movement; The move distance of left and right sides loose piece (11,21) equates that the direction of motion is opposite, left and right sides centering pinch roller (12,22) from about two directions press to ceramic tile, thereby reach the purpose of ceramic tile centering.Shown in Figure 6, when changing tile specification,, change mill 300mm now if former ceramic tile width is 450mm, at this moment need left crossbeam 1 and right crossbeam 2 are closed up toward the centre.Then drive long rack shaft 92 by lock-screw 5 and move right when left crossbeam 1 moves right, right crossbeam 2 is moved to the left and drives short rack shaft 91 by lock-screw 5 and is moved to the left simultaneously, and gear 93 is rotated counterclockwise.About two crossbeams (1,2) when meeting the requirements of width, centralising device center and edge polisher centering center line do not change.Need not adjust centralising device when therefore changing tile specification.But also there is shortcoming in this structure.As shown in Figure 6, during work, cylinder 8 active force P transfer ceramic tile to left and right sides centering pinch roller (12,22) reaction force F acts on left and right sides loose piece (11,21) on, the power of right loose piece 21 is delivered to gear 93 by short rack shaft 91, and one of them component passes in frame 7 by gear 93, another component makes gear 93 rotations become long rack shaft 92 active force left, and right crossbeam 21 is not subjected to this power effect; And the reaction force that is subjected to left centering pinch roller 12 of left loose piece 11, and active force is come by long rack shaft 92 transmission in the right side, it acts on the left crossbeam 1 by cylinder rod 81 with joint efforts, this will test the rigidity of crossbeam, if left crossbeam 1 this power effect under strain takes place, then influence the centering quality and then influence unfired brick quality.
Another shortcoming of above-mentioned two kinds of centralising devices is that rack shaft one end is fixed on the frame, and the other end is fixed on the loose piece, fixed base point is inconsistent, level-off and perpendicularity trouble, particularly long rack shaft, size is very long on wide specification edge polisher, more difficult accent, original centering force should very big (ceramic tile weight multiply by coefficient of friction), for example 800mm
2Ceramic tile weight 18kg, confficient of static friction maximum 0.5, centering force is need 〉=9kg only, but the actual 80mm cylinder that uses, compressed air is when 0.2MPa, produce the 102.5kg centering force, sometimes compressed air is high to 0.3MPa, can produce the 153.8kg centering force, use when the purpose of centering force will guarantee that exactly cylinder axis and rack shaft are sprained strength so greatly, can finish centering smoothly, when so big masterpiece is used on the crossbeam (above-mentioned second kind of centralising device structure left side crossbeam is subjected to this power), crossbeam is difficult to assurance strain does not take place.
The centralising device of above-mentioned two kinds of structures also has shortcoming to be, when adobe is very wide (for example 2m), it is very long that long rack shaft just becomes, and belongs to elongate rod, and himself gravity all can influence its linearity, poor stability.
Summary of the invention

The specific embodiment
Shown in Fig. 7 and 8, centralising device of the present invention is applied on the Ceramic Tiles edge polisher, it comprises left crossbeam 1, right crossbeam 2, guide shaft 6, left loose piece 11, right loose piece 21, left centering pinch roller 12 and right centering pinch roller 22, described left loose piece 11 is installed on the left crossbeam 1 by guide shaft 7, described right loose piece 21 is installed on the right crossbeam 2 by guide shaft 6, described left crossbeam 1 is provided with and drives the left cylinder 13 that left loose piece 11 moves along guide shaft 6, and described right crossbeam 2 is provided with and drives the right cylinder 23 that right loose piece moves along guide shaft; Described left cylinder 13 and right cylinder 23 are the adjustable stroke cylinder, and are provided with stage clip 3 between left cylinder rod 131 and the left loose piece 11.Above-mentioned stage clip 3 is provided with initial tension of spring adjusting nut 4.And right cylinder rod 231 is fixedlyed connected with right loose piece 21 by lock-screw 5.
The distance that the outer rim of described left centering pinch roller 12 is wired to the centering center line is wired to the distance of centering center line less than the outer rim of right centering pinch roller 22; Described two are less than or equal to 2mm apart from difference, and two are made as Δ X apart from difference, then Δ X≤2mm.
Centralising device of the present invention needs pre-adjustment before operate as normal:
1) adjust the cylinder stroke, suppose that the ceramic tile width is S, it is S/2 that then right cylinder stroke summit is wired to the centering distance between center line with regard to the outer rim of adjusting to right centering pinch roller; It is S/2-Δ X (Δ X≤2mm) that cylinder stroke summit, a left side is wired to the centering distance between center line with regard to the outer rim of adjusting to left centering pinch roller;
2) adjust the prestressing force of stage clip by the initial tension of spring adjusting nut, stage clip prestressing force is slightly larger than (the weight * 0.5 of ceramic tile), tries during adjustment to push away, and makes left centering pinch roller can promote ceramic tile and position that stage clip no longer shortens, prestressing force F0=k*X0 (k is a spring rate, and X0 is the initial compression amount)
This design need make left cylinder move (about 1/10 second, can adjust) early than right cylinder.Left side cylinder is earlier moving when centering, and when four centering pinch rollers all contacted ceramic tile, ceramic tile had been pulled to any the position of taking over, because right cylinder force greater than the left side spring force, will be got back to right cylinder stroke vertex position to the ceramic tile top, stage clip is compressed Δ X.When left and right sides loose piece returned after finishing centering, it was moving earlier to be still left cylinder, and at this moment stage clip is compressed Δ X amount and is released, and stage clip recovers substantially when right loose piece is return, and spring force release can not turned right ceramic tile and be pushed.
During work, right loose piece under right cylinder rod drives directly motion left arrive right cylinder stroke summit and stop, left side loose piece moves right under stage clip promotes, and in the time of on left centering pinch roller withstands on ceramic tile right centering pinch roller (four pinch rollers all contact with ceramic tile), left loose piece motion stops.Left cylinder rod also has stroke because the motion of left loose piece stops, thereby left cylinder rod continues to move to the stroke summit, and stage clip is compressed.The suffered centering force of left and right sides crossbeam this moment then derives from the distortion of stage clip, and this power is slightly larger than frictional force (ceramic tile weight * confficient of static friction 0.5), can not make the crossbeam strain.
Present embodiment is the another kind of embodiment of centralising device of the present invention, its place different with embodiment 1 is, be provided with stage clip between right cylinder rod and the right loose piece, above-mentioned stage clip is provided with the initial tension of spring adjusting nut, and left cylinder rod is fixedlyed connected with left loose piece by lock-screw, changes embodiment 2 on the left of being located at when promptly stage clip is by embodiment 1 and is made as the right side.
The distance that the outer rim of described right centering pinch roller is wired to the centering center line is wired to the distance of centering center line less than the outer rim of left centering pinch roller; Described two are less than or equal to 2mm apart from difference.
Other structure of present embodiment is as described in the embodiment 1, this no longer superfluous saying.
The present invention has the following advantages:
1) the present invention adopts the adjustable stroke cylinder as drive unit, and cancellation tooth bar, gear transmission structure make installation simple and convenient, eliminate the strength point of spraining of centralising device; Cylinder rod is loaded on loose piece center (and existing centralising device cylinder does not hit exactly installation), improves the cylinder rod working condition, thereby can reduce centering force, promptly is slightly larger than ceramic tile weight and multiply by coefficient of friction, and then can reduce cylinder bore.
2) centralising device of the present invention is owing to saved tooth bar, gear transmission structure; about centralising device left and right sides two parts are loaded on respectively on two crossbeams; then to be two crossbeam center lines also be that the centralising device center line is constant to edge polisher centering center line; when then changing the adobe specification; two crossbeams close up or separate; its centering center line is consistent with the crossbeam center line all the time, need not to adjust again.
3) centralising device of the present invention two crossbeams when centering all are subjected to equal-sized centering force, but owing to increased the utilization that to adjust prestressed stage clip structure and adjustable stroke cylinder, essential change has taken place with comparing with the centering force of pre-structure in this power, transverse beam rigidity is not made a difference.
4) reduce cost.
