Abstract
The utility model discloses a plasma cutting machine tool for plates. The plasma cutting machine tool for the plates comprises a working table, feeding and discharging mechanisms, a plasma cutting machine, a guide rail and a PLC. The plasma cutting machine is connected with the PLC, the guide rail is arranged on one side of the working table, and the length direction of the guide rail is the same as that of the working table. The plasma cutting machine is arranged on the guide rail, a camera is arranged above the working table in a sliding mode, a lens of the camera is over against the working table, and the camera is connected with the PLC. Due to the facts that the camera is arranged and used for shooting positions of positioning holes in the plates, the starting point for cutting and the deflection angle, relative to the working table, of the plates can be determined with the positioning holes as positioning points, the plasma cutting machine cuts the plates without being affected by size errors of the length and width of the plates, and the edges of the cut plates are accurate in size relative to the positioning holes.
Description
Technical field
The utility model relates to a kind of plate cutting machine tool.
Background technology
Automobile longitudinal girder is to be pressed into U-shaped section bar by steel plate stamping, in the time of punching press, be to ensure that the flange of steel plate both sides is measure-alike, multiple locating holes generally will be set on the center line of steel plate, when punching press, by insert alignment pin in locating hole, steel plate is fixed on workbench, steel plate is before punching press, need to steel plate edge carry out cutting process, such as corner cut cyclotomy arc etc.
In the time that sheet material is cut, be all that edge using sheet material is as gulde edge.After so just causing cutting, new sheet edge cannot ensure to the distance of locating hole.In the time cutting, if using locating hole as location, need to manually add alignment pin.Then,, after cutting off machine is moved on alignment pin, position.Locating hole is generally each one of sheet material front end and sheet material rear end.While encountering sheet material and be the sheet material of 11 meters, the time of artificial location is very long.In the time manually adding the location of alignment pin, alignment pin is through application for a long time, and easily loosening, location there will be larger deviation.
Utility model content
Problem to be solved in the utility model is: provide a kind of accurate positioning high sheet material CUT bed.
For addressing the above problem, the utility model sheet material CUT bed, comprise workbench, charging and discharging mechanism, CUT, guide rail and PLC controller, CUT connects PLC controller, and guide rail is arranged on a side of workbench, the length direction phase of the length direction of guide rail and workbench, CUT is arranged on guide rail, slide and be provided with camera in described workbench top, the camera lens of camera is just to workbench, and camera connects PLC controller.
For cylinder machine tool structure, described camera is fixed on CUT.
For the ease of obtaining the move distance of CUT, between described CUT and guide rail, be provided with the encoder of measuring CUT move distance.
For the ease of loading and unloading, described charging and discharging mechanism is automatic loading and unloading mechanism.
The beneficial effects of the utility model: the utility model lathe is owing to being provided with camera, take the position of locating hole on sheet material by camera, thereby can determine taking the locating hole on sheet material as anchor point the starting point of cutting and the drift angle of the relative workbench of sheet material, make CUT cutting not be subject to the impact of the length of sheet material and the scale error of width, the sheet edge relative positioning hole dimension after cutting is accurate.

Detailed description of the invention
The automatic positional dissection lathe of a kind of sheet material as shown in Figure 1, comprise workbench 5, guide rail 6, charging and discharging mechanism, CUT 4 and PLC controller 3, CUT 4 connects PLC controller 3, guide rail 6 is arranged on a side of workbench 5, the length direction phase of the length direction of guide rail 6 and workbench 5, CUT 4 is arranged on guide rail 6, slide and be provided with camera 7 in the top of workbench 5, in order to save guide rail, camera 7 can directly be fixed on CUT 4 by a crossbeam, the camera lens of camera 7 is just to workbench 5, camera 7 connects PLC controller 3.Workbench 5 is arranged on ground 1.
Between CUT 4 and guide rail 6, be provided with the encoder of the move distance of CUT 4.Also can adopt other method to measure.Charging and discharging mechanism preferably adopts automatic loading and unloading mechanism 2.
Above-mentioned cutting off machine is in the time of cuts sheet material, adopt following method: known conditions, as shown in Figures 2 and 3, on the center line of the length direction of sheet material 8, be provided with multiple locating holes, cutting starting point is with respect to the relative position (a of nearest locating hole, b), a represent to cut starting point with respect to nearest locating hole the relative difference at sheet material width, b represent to cut starting point with respect to nearest locating hole the relative difference at sheet material width length direction.
This cutting method comprises the steps:
(1) sheet material 8 is placed on workbench 5, the length direction of sheet material 8 on the length direction of workbench, arranges the plane coordinate system of workbench 5 substantially, the length direction of workbench represent X to, the width of workbench represents Y-direction;
(2) take the locating hole A of the leftmost side on sheet material 8 with camera 7, at the X camera 7 that moves up, displacement is x, take again the locating hole B of the rightmost side on sheet material with camera 7, get the coordinate figure (XX1 of locating hole A in captured image, YX1), the coordinate figure (XX2, YX2) of locating hole B in captured image and x calculate sheet material center line with respect to X to deviation angle θ;
The computational methods of θ:
△Y=YX2-YX1
Tan(θ)=?△Y/(?XX2+x-?XX1)
θ=arctan（(YX2-YX1)/(?XX2+x-?XX1)）
This θ angle is exactly the gradient of sheet material 8 relative workbench 5.
(3) calculate the coordinate (XC, YC) that cutting starting point C fastens at the plane coordinates of workbench;
Coordinate (XC, YC) computational methods 1:
XC?=?X1+b·Cos（θ）-?a·Sin（θ）
YC=Y1+b·Sin（θ）+a·Cos（θ）
The coordinate of the center that (X1, Y1) is the nearest locating hole of cutting starting point in the plane coordinate system of workbench.
All adopt same long measure for the ease of the coordinate figure of computing camera, plane coordinates value and a, the b of workbench, can directly calculate like this, do not need unit conversion.
Above-mentioned θ, (XC, YC) are calculated as accurate Calculation, also can utilize above-mentioned known conditions to adopt easy approximate calculation.
(4) coordinate figure that CUT is fastened at the plane coordinates of workbench according to θ, cutting starting point and the cut shape cuts sheet material of setting.
