Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

Embodiment: Please refer to Fig. 1 and Fig. 2, a kind of multiple riveting mold, this mold comprises the upper mold body and the lower mold body that cooperate to realize riveting; Upper backing plate 3, splint 4, back supporting plate 5 and stripping plate 6, lower mold body comprises lower formwork 7, lower backing plate 8, lower mold base 9 and lower foot 10 successively, between described upper and lower mold body A position sensing structure 11 is also provided, and the position sensing structure 11 is arranged between the upper template 2 and the lower template 7; the lower mold body 7 is also provided with a riveting detection mechanism 12 .

Please refer to Fig. 1 and Fig. 2, the aforementioned riveting detection mechanism 12 is arranged in the lower mold body and can contact with the processing surface of the riveting contact point C of the workpiece A and workpiece B at the upper end of the lower mold body to form a riveting detection structure. The riveting detection mechanism 12 includes two groups of optical fiber detection groups. The two groups of optical fiber detection groups are respectively located before and after the riveting contact point to form the detection of the riveting contact point C. Each group of optical fiber detection groups includes an optical fiber probe 121 and an optical fiber sensor 122. , the fiber optic probe 121 is located below the riveting position of the workpiece A and the workpiece B and is connected to the external fiber optic sensor 122 through a fiber optic wire.

1 and 2, the aforementioned position sensing structure 11 includes a sensing metal sheet 111, a proximity switch 112, and a lifting frame 113. One end of the sensing metal sheet 111 is fixed below the lower mold base 2 and can be arranged horizontally on the lifting frame. The proximity switch on 113 contacts 112 to form a position sensing frame. The lifting frame 113 is a frame body with one end fixed on the lower formwork, and the frame body is provided with a threaded rod, and the two ends of the threaded rod are respectively positioned with nuts, and then Achieve lifting.

Detection steps and principles of the present utility model are as follows:

1. Embed the optical fiber riveting detection mechanism 12 at the position marked in the figure, and set the threshold value (when the reflection intensity reaches a certain value, the signal will be output);

2. When the upper mold body goes down to a certain position, the proximity switch 112 senses the metal sheet 111 (preferably an iron sheet), and sends out a signal;

3. When a material passes directly above the optical fiber riveting detection mechanism 12, the optical fiber sensor outputs a signal. If the material is not riveted, the optical fiber sensor cannot sense the object and does not send out a signal;

4. Logical judgment is carried out by PLC or single-chip microcomputer. When the proximity switch has a signal (the stamping setting stroke has reached the set position, the feeding is completed, and the inspection is started), at this time, when the optical fiber has an output signal, the riveting is normal, and no shutdown command is issued; when the optical fiber When there is no signal output, the material is not riveted, a shutdown command is issued, and defective products are manually eliminated to achieve the preset purpose.

The above records are only examples of using the technical content of this creation. Any modifications and changes made by those who are familiar with this technology using this creation belong to the scope of patents claimed by this creation, and are not limited to those disclosed in the examples.
