Abstract
The utility model discloses equipment for detecting the internal defect of a tire. The equipment comprises a low pressure chamber capable of accommodating the tire to be detected, low pressure generation equipment capable of forming low pressure environment in the low pressure chamber, a light source capable of emitting incident light to the surface of the tire, an imaging objective arranged on a reflected light path of the incident light, a beam splitting prism matched with the imaging objective, and a charge coupled device (CCD) image sensor. By the equipment, traffic accidents are reduced by detecting whether the defect exists in the tire or not.
Description
Technical field
The utility model relates to a kind of inside tires defect detection equipment.
Background technology
Because there is defective in tire, automobile is when running at high speed, and shear strain easily occurs fault location, causes subduing Sheng Re and stress and concentrates, so that defective constantly enlarges.At present, the traffic hazard that highway occurs, 2nd/3rd, because the initiation of wheel tyre defect, some wheel tyre defects occur in the tread rubber place, and what have occurs in the carcass, and occur in the defective in the carcass, very easily cause blowing out, yet, whether there is defective in the carcass, can not distinguish by naked eyes, so that have defective to become to lead to the stealthy killer of traffic accident in the carcass, very harmful, so, demand occurring a kind of method or the generation of equipment to cut down traffic accidents that can detect the inside tires defective urgently.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of inside tires defect detection equipment, has realized whether having defective by detecting inside tires, with the generation that cuts down traffic accidents.
For reaching this purpose, the utility model by the following technical solutions:
A kind of inside tires defect detection equipment comprises the low-pressure chamber that can hold tire to be detected, the low pressure generation that can form environment under low pressure in described low-pressure chamber, can launch the Amici prism of the light source of incident light, the catoptrical image-forming objective lens that cooperates described incident light, the described image-forming objective lens of cooperation, the ccd image sensor of the described Amici prism of cooperation to described surface of tyre.
Also comprise and make described tire in the travel mechanism of described vacuum indoor moving.
Also comprise the catoptron that cooperates described Amici prism.
Described catoptron and/or described catoptron band piezoelectric ceramics.
Described low pressure generation is vacuum generating equipment.
Described light source is laser instrument.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
In the utility model, at first tire is sent into low-pressure chamber, tire table wall each point is carried out image acquisition, open the low pressure generation, make low-pressure chamber be in vacuum state, again tire table wall each point is carried out image acquisition, if there is defective in inside tires, under the inside and outside differential pressure effect, can make surface of tyre expansion point can occur, namely can find relatively to can be used as the difference that exists in the image and judge the foundation that whether has defective in the tire, and can judge the position of inherent vice.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1:
Wherein: 1, low-pressure chamber; 2, tire; 3, Amici prism; 4, catoptron; 5, catoptron; , ccd image sensor; 7, light source; 8, image-forming objective lens; 9, low pressure generation.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
A kind of inside tires defect detection equipment is proposed, comprise the low-pressure chamber 1 that can hold tire 2 to be detected, low pressure generation 9 is vacuum generating equipment, can be in low-pressure chamber 1 interior manufacturing vacuum environment, by operation travel mechanism, tire 2 can be in low-pressure chamber 1 interior movement, light source 7 is laser instrument, can be to the surface local Emission Lasers of tire 2 as incident light, incident illumination is mapped to after tire 2 surfaces, laser as incident light reflects, and is provided with image-forming objective lens 8 at its reflected light path, and image-forming objective lens 8 cooperates with Amici prism 3, image is passed to ccd image sensor 6, for reaching best light efficiency, catoptron 4,5 cooperate Amici prism 3, catoptron 4 and/or catoptron 5 band piezoelectric ceramics.
Following implementation to embodiment 1 further describes:
Among the embodiment 1, at first tire 2 is sent into low-pressure chamber 1, tire 2 table wall each points are carried out image acquisition, open low pressure generation 9, make low-pressure chamber 1 be in vacuum state, again tire 2 table wall each points are carried out image acquisition, if there is defective in tire 2 inside, under the inside and outside differential pressure effect, can make tire 2 surfaces expansion point can occur, namely can find relatively to can be used as the difference that exists in the image and judge whether tire 2 inside exist the foundation of defective, and can judge the position of inherent vice.
The above; it only is the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
