Abstract
The utility model provides an on-line laser thickness measuring device, which comprises a frame and measuring probes, wherein the frame is a C-shaped frame mounted on an operating platform, and the measuring probes opposite to each other vertically are arranged respectively at the ends of an upper arm and a lower arm of the frame. A conveying device is arranged in the middle of the C-shaped frame and penetrated between the upper arm and the lower arm of the C-shaped frame, and a measured object is arranged on the conveying device. Laser beams emitted by the upper measuring probe and the lower measuring probe are cast vertically on the upper and lower surfaces of the measured object from the upper and lower directions, and the dynamic thickness of the measured object on the conveying device can be obtained according to the double-path laser-CCD thickness measuring principle. Due to the adoption of the on-line laser thickness measuring device, high-temperature heat-rolled on-line measurement is achieved, and human body can be prevented from the harm of X-ray.
Description
Technical field
The utility model relates to a kind of laser measuring device for measuring.
Background technology
Mill in steel mill, the high temperature hot rolling is carried out under 1000 ℃ of left and right sides situations, if just measure after waiting the product cooling, the error that then causes producing in the operation of rolling will be a batch property, will bring than large economy to factory and lose.Domestic hot rolling line adopts X ray high temperature thickness measuring equipment more at present, costs an arm and a leg, and the X-ray tube life-span is short, and X ray itself has certain injury to human body.
The utility model content
The technical problem that the utility model will solve is to overcome existing defective, and a kind of online thickness measurement with laser device is provided, and can carry out thickness measuring to hot-rolled steel, and avoids the injury of ray to human body.

A kind of online thickness measurement with laser device of the utility model can carry out high temperature hot rolling on-line measurement, exempts the injury of X ray to human body.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of online thickness measurement with laser device of the utility model;
Fig. 2 is the structural representation of the measuring probe of a kind of online thickness measurement with laser device of the utility model.
The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 2, measuring probe comprises laser instrument 11, line array CCD 10, receiver lens 15, probe cassette 9 and laser power supply 12 and three synchronous line array CCD drive circuits 13, plus lens 14.
Connect laser power supply 12 and three synchronous line array CCD drive circuits 13, laser instrument 11 emission laser beams receive reverberation then to the testee surface, utilize CCD10 to detect again.At first, the light beam that laser instrument 11 sends sees through plus lens 14 vertical irradiations to zero plane of reference, forms a hot spot; This hot spot reflects on zero plane of reference, forms folded light beam (because zero plane of reference is chosen as optical axis position, therefore; This folded light beam is optical axis); Be imaged on the line array CCD 10 through receiver lens 15, will form a picture point, this picture point just has a position on CCD10; When testee is put on zero plane of reference; The light beam that laser instrument 11 sends will vertical irradiation to tested object plane, form a hot spot, this hot spot reflects on tested object plane; Form folded light beam; Be imaged on the line array CCD 10 through receiver lens 15, will form a picture point, this picture point has a position again on CCD10.Picture point is laser beam from picture point on CCD10 the position changing value of vertical irradiation to zero plane of reference to tested object plane time spot in the difference of two positional values on the CCD10, again according to the geometrical relationship of triangulation principle, can draw the one-tenth-value thickness 1/10 of tested object plane.
As shown in Figure 1, last measuring probe 3 is fixed on the upper arm termination of C-form stand 2, measuring probe 4 down is fixed on the underarm termination of C-form stand 2, and makes measuring probe 3 relative with following measuring probe 4.C-form stand 2 is installed on the workbench 1.
Conveyer 5 is placed the centre of C-form stand 2, conveyer 5 is passed between the last underarm of C-form stand 2, testee 6 is placed on the conveyer 5.
Power-on; Last measuring probe 3 and following measuring probe 4 emitted laser bundles 7,8 from about both direction be vertically projected to two surfaces up and down of testee 6; According to two-way laser-CCD thickness measure principle, can draw the dynamic thickness of testee 6 on conveyer 5 again.
The above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
