The using method comprises the following steps:
when the device is specifically used, two first detection parts are arranged along the length direction of the lathe bed main body 1, and a second detection part is arranged along the width direction of the lathe bed main body 1;
Feeding through the feeding end of the lathe body 1 to enable materials to enter between the two first detection parts and the second detection part;
the first telescopic rod 2 stretches to enable the length direction of the detection arm 16 to be perpendicular to the length direction of the bed body 1, one detection roller 18 is in contact with the length direction of the material, and at the moment, the brake rod 20 stretches to brake the spring rotating shaft 4;
the guide frame 6 is driven to walk along the direction of the guide screw rod 5 by the operation of the guide motor 7;
The guide motor 7 drives the guide screw rod 5 to drive the first detection part to move along the length direction of the lathe bed main body 1, so that the detection roller 18 walks along the surface of the material;
In order to facilitate the detection work, a circle of pressure sensors are arranged on the connecting rotating shafts of the detection roller 18 and the detection arm 16, and when the surface of the material is smooth, the pressure value detected by the pressure sensors is a standard value; when the detection roller 18 walks to the convex part or the concave part of the material, the extrusion force of the detection roller 18 to the pressure sensor is gradually increased along with the movement of the first telescopic rod 2, when the pressure value detected by the pressure sensor is smaller than the set pressure threshold, the first telescopic rod 2 is shortened until the pressure value detected by the pressure sensor is close to a standard value, so that the detection roller 18 passes through the convex part of the surface of the material, and when the pressure value detected by the pressure sensor is smaller than the standard value, the first telescopic rod 2 is stretched, so that the detection roller is always abutted against the surface of the material, as shown in the middle part of fig. 10;
The setting of the pressure threshold, the standard value and the allowable pressure difference may be set according to the working strength, the workpiece surface flatness, the surface friction of the detecting roller 18, etc. in the actual production process, and will not be described herein.
When the detection roller 18 walks to the second state of the first detection part as shown in fig. 11 and the protruding part of the workpiece is protruding or bending angle is larger, the pressure detected by the pressure sensor is larger than the set pressure threshold, the detection roller 18 does not extend or shorten through the irregular part of the material through the extension or shortening of the first telescopic rod 2, and at the moment, the brake rod 20 is shortened, and the brake on the spring rotating shaft 4 and the connecting shaft 3 is released;
The detection arm 16 and the connecting shaft 3 relatively rotate, the rotation angle of the detection arm 16 is detected by the angle sensor 17, and simultaneously, as the detection arm 16 rotates, the first telescopic rod 2 stretches, so that the pressure value detected by the pressure sensor is always equal to the standard value;
When the detection roller 18 approaches the outer part of the material, as shown in a third state shown in fig. 12 and a fourth state shown in fig. 13, at this time, under the action of the spring rotating shaft 4, the detection roller 18 is rapidly pressed towards the direction of the material after passing through the outer part, so that the detection roller 18 can be contacted with the outer edge of the main body of the material again along the edge of the outer part, and during this time, the other detection roller 18 can guide the movement of the first detection component, so as to ensure the stable movement of the first detection component.
When the second detection part operates, the second telescopic rod 8 stretches, the second telescopic rod 8 pushes the connecting push rod 12 to move towards the outside of the material, and when the detection rod 11 reaches the outside of the material, the pushing cement 13 deforms to push the detection rod 11 to be attached to the irregular position on the surface of the material with high efficiency;
the lower extreme of detection pole 11 and the contact 15 of detecting bottom plate 10 contact, form the detection return circuit between detection pole 11, detecting bottom plate 10 and the deflector 9, and the line of a plurality of detection poles 11 and detecting bottom plate 10 contact position is the outward flange shape profile of material.
When the material thickness is small, the material is located between the guide plate 9 and the detection bottom plate 10. When the material is high and is greater than the height of the second detecting portion, the installation position of the second detecting portion is moved downward, and the shape of the outer edge of the material is detected by the upper end of the detecting lever 11, for which reason the second detecting portion can be set to a liftable structure according to the prior art.
When the shape of the material is shot through the shooting module, the upper shape of the material can cover the lower shape of the material to a certain extent, and the method has certain defects. If the shapes of the workpieces at different heights are detected, the detection part of the application can be arranged at different heights for operation.
The foregoing embodiments are merely specific examples of the present invention, and the scope of the present invention includes, but is not limited to, the product forms and styles of the foregoing embodiments, and any suitable changes or modifications made by one of ordinary skill in the art, which are consistent with the claims of the present invention, shall fall within the scope of the present invention.
