The utility model skillfully utilizes the color difference of the welding point, combines the color sensor with the existing clamp, does not need to carry out other changes on equipment, but solves the problem which is difficult to solve for a long time, realizes online automatic detection, solves the problems of low manual detection efficiency and easy error, and also avoids the occurrence of unqualified products.
Description
Technical Field
The utility model relates to an online detection mechanism for an automobile outer threshold reinforcement, and belongs to the technical field of automobile machining.
Background
In the outer doorsill of the automobile, in order to increase the strength of the doorsill and ensure that the weight is not excessively increased, a reinforcing part with a hollow design is adopted, the structure of the reinforcing part is similar to that of a hollow rectangular body, welding lugs are connected to the outside of the hollow rectangular body, and 4 reinforcing parts are welded in the outer doorsill side by side.
The reinforcement is a semi-finished process part and needs to be machined first and then welded to the doorsill. One side surface of the rectangular body is formed by folding and stacking two half plates, wherein two positioning holes are formed in one half plate, and a positioning bulge is formed in the other half plate and just correspondingly sinks into the positioning holes to realize positioning. The two positioning points need to be welded together, however, the two welding points of the reinforcing piece are difficult to distinguish between welding and non-welding, the two welding points are difficult to identify from the appearance by workers, error identification is easy to cause, and the reinforcing piece with the two points which are not welded is welded on the doorsill.
From the aspect of product quality, the outer doorsill without welding needs to be scrapped, and the production yield of the product is influenced; from the car, once the defect part is welded on whole car, there is the potential safety hazard, probably leads to whole car unqualified. However, in the prior art, there is no problem of equipment inspection, and only field management is relied on, so that there is a great risk. Moreover, the method depends on manual inspection, and has low efficiency and high error probability.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides an online detection mechanism for an automobile outer threshold reinforcement.
In order to achieve the purpose, the technical means adopted by the utility model is as follows: an online detection mechanism for an automobile outer threshold reinforcement is characterized in that a color sensor is arranged on a clamp and connected with a control system, and the color sensor corresponds to a positioning welding spot.
Furthermore, the number of the color sensors is two, and the two color sensors correspond to the two positioning welding points respectively.
Further, a sensor mounting frame is arranged on the clamp body, the color sensor is fixed on the sensor mounting frame, and a probe of the color sensor faces the positioning welding spot.
The working principle is as follows: when the reinforcing part is clamped by the clamp and placed at the installation position of the outer threshold, the color sensor is arranged at the position, corresponding to the positioning welding spot, on the clamp, and online detection is realized according to comparison of welding and unwelded color difference. For detecting the reinforcement which is not welded, the reinforcement is thrown into a region to be processed by a clamp, or is subjected to sound and/or light alarm and manual processing; for detecting the welded reinforcement, welding of the reinforcement to the outer sill is performed.
The utility model has the beneficial effects that: because the color difference of the welding point is ingeniously utilized, the color sensor is combined with the existing clamp, other changes to the equipment are not needed, the problem which is difficult to solve for a long time is solved, the online automatic detection is realized, the problems of low manual detection efficiency and easy error are solved, and the occurrence of unqualified products is also avoided.

Detailed Description
As shown in the online detection mechanism of the automobile outer threshold reinforcement in the figures 1 and 2, a color sensor 4 is arranged on a special welding fixture for the outer threshold corresponding to a positioning welding spot 3, the color sensor 4 is connected with a control system, and when the fixture clamps the reinforcement 1 and places the reinforcement 1 at the installation position of the outer threshold 2, online detection is realized according to the comparison of the welding color difference and the non-welding color difference.
For detecting the reinforcement which is not welded, the reinforcement is thrown into a region to be processed by a clamp, or is subjected to sound and/or light alarm and manual processing; for detecting the welded reinforcement, welding of the reinforcement to the outer sill is performed.
Preferably, two color sensors 4 are provided, corresponding to the two tack welds 3. The purpose of the two welding holes is to prevent the occurrence of welding missing when the positioning welding points of the reinforcing member 1 are welded.
As the specific design, the fixture body is provided with a sensor mounting frame, the color sensor 4 is fixed on the sensor mounting frame, and the probe of the color sensor faces the positioning welding point 3.
The utility model skillfully utilizes the color difference of the welding point, combines the color sensor with the existing clamp, does not need to carry out other changes on equipment, but solves the problem which is difficult to solve for a long time, realizes online automatic detection, solves the problems of low manual detection efficiency and easy error, and also avoids the sending of unqualified products.
Although particular embodiments of the utility model have been described and illustrated in detail, it should be understood that various equivalent changes and modifications could be made to the above-described embodiments in accordance with the spirit of the utility model, and the resulting functional effects would still fall within the scope of the utility model.
