Description
Technical Field
The utility model belongs to the technical field of the sub vehicle frame detects technique and specifically relates to a detection device of sub vehicle frame inside projection nut.
Background
And (4) projection welding nuts on the auxiliary frame to firmly connect the two workpieces together. Because the projection welding nut is in the inside of sub vehicle frame, the condition of neglected loading takes place easily in process of production, does not have effectual detection device moreover, is difficult to prevent the spilling over of sub vehicle frame defect spare in the process of production.
Therefore, the detection device for the projection welding nuts in the auxiliary frame needs to be designed to avoid the condition of neglected loading of the nuts and prevent the overflow of defective parts in the production process.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art, providing a detection device of sub vehicle frame inside projection welding nut to avoid the condition of nut neglected loading, prevent spilling over of defect spare in the production process.
In order to achieve the purpose, the utility model relates to a detection apparatus for sub vehicle frame inside projection welding nut, including installing support, fixed cover, spring, detection round pin, sensor, its characterized in that: the upper end of fixed cover passes the installing support, it sets up in the fixed cover to detect the round pin, be equipped with protruding structure in the fixed cover, the lower part of detecting the round pin passes protruding structure, the upper portion nut sense terminal that detects the round pin passes the upper end of fixed cover, be equipped with the boss on the detection round pin, the spring housing is established in the middle part outside of detecting the round pin, the upper end of spring and the lower surface contact of boss, the lower extreme of spring and the upper surface contact of protruding structure, the lower extreme of fixed cover inlays and is equipped with the sensor, the sense terminal of sensor and the bottom contact or.
The sensor is a Barufu proximity switch BESM12MI-PSC40B-BP0 inductive sensor.
The mounting bracket is mounted at the bottom of the auxiliary frame.
The elastic coefficient of the spring is 0.8N/mm.
Compared with the prior art, the utility model, designed the detection device of the inside projection nut that welds of sub vehicle frame, inside inserting the work piece, can judge whether the nut exists, avoid the condition that the nut neglected loading, can effectively prevent spilling over of defect spare in the production process. The utility model is suitable for an inside nut in work piece die cavity detects.
Drawings
Fig. 1 is a structural diagram of the present invention.
Detailed Description
The invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1, the utility model relates to a detection apparatus for sub vehicle frame inside projection welding nut, including installing support, fixed cover, spring, detection round pin, sensor, its characterized in that: the upper end of fixed cover 2 passes installing support 1, it sets up in fixed cover 2 to detect round pin 4, be equipped with protruding structure 6 in fixed cover 2, the lower part that detects round pin 4 passes protruding structure 6, the upper portion nut sense terminal that detects round pin 4 passes the upper end of fixed cover 2, be equipped with the boss on detecting round pin 4, 3 covers of spring are established in the middle part outside that detects round pin 4, the lower surface contact of the upper end of spring 3 and boss, the lower extreme of spring 3 and the upper surface contact of protruding structure 6, the lower extreme of fixed cover 2 inlays and is equipped with sensor 5, sensor 5's sense terminal and the bottom contact or the separation that detects round pin 4.
In the present invention, the sensor 5 is preferably a Barruff proximity switch BESM12MI-PSC40B-BP0 inductive sensor. The spring 3 preferably has a spring constant of 0.8N/mm.
The utility model discloses the during operation, installing support 1 installs the bottom at the sub vehicle frame. The upper nut detection end of the detection pin 4 penetrates through the first workpiece 7 and the second workpiece 8, if the nuts 9 exist in the first workpiece 7 and the second workpiece 8, the nuts 9 abut against the detection pin 4, the detection pin 4 moves downwards, the boss of the detection pin 4 compresses the spring 3, the detection end of the sensor 5 is in contact with the bottom of the detection pin 4, and the sensor 5 detects a signal, so that the correct installation of the projection welding nuts in the auxiliary frame can be confirmed. After the upper nut detection end of the detection pin 4 leaves the nut 9, the detection pin 4 is reset under the action of the spring 3, the detection end of the sensor 5 is separated from the bottom of the detection pin 4, and the sensor 5 is reset.
If the nuts 9 are neglected to be installed in the first workpiece 7 and the second workpiece 8, no object can abut against the detection pin 4 after the upper nut detection end of the detection pin 4 penetrates through the first workpiece 7 and the second workpiece 8, the detection pin 4 is in an initial position under the action of the spring 3, the detection end of the sensor 5 is separated from the bottom of the detection pin 4, and the sensor 5 has no signal, so that the neglected installation of the projection welding nuts in the auxiliary frame can be confirmed.
The utility model discloses a detection apparatus for the inside projection nut that welds of sub vehicle frame inserts inside the work piece, can judge whether the nut exists, avoids the condition of nut neglected loading, can effectively prevent spilling over of defect spare in the production process. The utility model is suitable for an inside nut in work piece die cavity detects.
