Description
Technical Field
The invention relates to a nut detection method.
Background
The nut needs to be installed at the given position of the product, the nut is installed for the given portion of guaranteeing the product, it needs to detect it, what adopted at first is manual detection, it is hard and time-consuming and produce the false detection easily, afterwards, in order to improve the detection precision, adopt the metal inductor to detect, the principle of metal inductor is that the product body is nonmetal, the nut is metal, therefore can carry out effective detection, but when the metal inductor detects a problem that exists, when the nut can not effectively paste with the metal inductor, namely when there is great clearance in the given position of metal inductor and product, the wrong condition of response can appear in the metal inductor, therefore, how to effectively improve the precision of check out test set becomes the technical problem that technical staff in the field awaited a great deal of solution.
Disclosure of Invention
The invention aims to provide a nut detection method which is high in detection accuracy.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a nut detection method utilizes detection equipment to detect whether a nut is installed at a given position of a product, and comprises the following steps:
1) the detection equipment comprises a workbench, wherein a supporting bottom die is arranged on the workbench, a supporting column is arranged on the supporting bottom die, a spring is arranged on the supporting column, a metal inductor is arranged on the spring and used for elastically supporting the metal inductor, the metal inductor is used for contacting a set part of a product, which is provided with a nut, and sensing whether the nut exists or not, a pressure sensor is arranged on a spring body and used for sensing the pressure applied to the spring;
2) the product is placed on the supporting bottom die, the set part of the product, which is provided with the nut, is pressed on the metal inductor, when the pressure range sensed by the pressure sensor is within the specified range, the result sensed by the metal inductor is collected, and when the pressure range sensed by the pressure sensor is not within the specified range, the product is placed on the supporting bottom die again.
Preferably, in step 2), when the pressure range sensed by the pressure sensor is within a specified range, the result sensed by the metal sensor is collected, and the result sensed by the metal sensor is displayed through the indicating lamp.
The working principle of the invention is as follows: when the spring is pressed, the metal inductor is effectively attached to the set part of the product, which is provided with the nut, the acquired result sensed by the metal inductor is an accurate result, and the effect of the pressure sensor is just to prove that the spring is in a pressed state; when the pressure sensor does not sense that the spring is stressed, the metal sensor is probably not effectively attached to the set part of the product, and a large gap exists between the metal sensor and the set part of the product, so that the result sensed by the metal sensor is probably incorrect, and the product needs to be replaced, so that the metal sensor is effectively attached to the set part of the product.
The invention has the beneficial effects that: the detection precision is high.

FIG. 1 is a schematic view of a detection apparatus employed in the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The technical scheme of the specific implementation of the invention is as follows:
as shown in figure 1 of the drawings, in which,
a nut detection method utilizes detection equipment to detect whether a nut is installed at a given position of a product 7, and comprises the following steps:
1) the detection equipment comprises a workbench 1, wherein a supporting bottom die 2 is arranged on the workbench 1, a supporting column 6 is arranged on the supporting bottom die 2, a spring 4 is arranged on the supporting column 6, a metal inductor 3 is arranged on the spring 4, the spring 4 is used for elastically supporting the metal inductor 3, the metal inductor 3 is used for contacting a set part of a product 7, which is provided with a nut, and sensing whether the nut exists or not, a pressure sensor 5 is arranged on a spring 4 body, and the pressure sensor 5 is used for sensing the pressure applied to the spring 4;
2) the method comprises the steps of placing a product 7 on a supporting bottom die 2, pressing a set part, which is to be provided with a nut, of the product 7 on a metal inductor 3, collecting a result sensed by the metal inductor 3 when a pressure range sensed by a pressure sensor 5 is within a specified range, and placing the product 7 on the supporting bottom die 2 again when the pressure range sensed by the pressure sensor 5 is not within the specified range.
In the step 2), when the pressure range sensed by the pressure sensor 5 is within a specified range, the result sensed by the metal sensor 3 is collected, and the result sensed by the metal sensor 3 is displayed through the indicating lamp.
The working principle of the invention is as follows: when the spring 4 is pressed, it is indicated that the metal inductor 3 is effectively attached to the predetermined part of the product 7 where the nut is to be installed, the acquired result sensed by the metal inductor 3 is an accurate result, and the action of the pressure sensor 5 is just to prove that the spring 4 is in a pressed state; when the pressure sensor 5 does not sense that the spring 4 is pressed, it indicates that the metal sensor 3 is likely not to be effectively attached to the predetermined portion of the product 7, and a large gap exists therebetween, which indicates that the result sensed by the metal sensor 3 is likely to be incorrect, and the product 7 needs to be replaced, so that the metal sensor 3 is effectively attached to the predetermined portion of the product 7.
The invention has the beneficial effects that: the detection precision is high.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
