Description

Piece test fail-safe system in welding process

Technical field

This utility model is related to a kind of detecting system, piece test fail-safe system in more particularly to a kind of welding process.

Background technology

In Ford wing tiger project, two drive and there are a symmetrical part in 4 wheel driven, and 4 wheel driven is drawing empty circle There is nut in part, as shown in Figure of description Fig. 1, and two drives do not have nut, such as Figure of description Fig. 2 in the part for drawing empty circle It is shown；The 4 wheel driven part can be welded on two drive part stations, due to welding during 4 wheel driven part, arc-welding station welding slag meeting Face on a sensor of dropping causes sensor Chang Liang, and moment sensor can only detect the existence of part, long for sensor It is bright, can not solve the problems such as how to control welding unit normal work, i.e., in the case where original station welding system is not changed, How nonadherent on a sensor to realize welding slag using detecting system, this is the problem that we now urgently need to solve at present.

Utility model content

This utility model is intended at least solve technical problem present in prior art, especially innovatively proposes a kind of weldering Piece test fail-safe system in termination process.

In order to realize above-mentioned purpose of the present utility model, this utility model is prevented there is provided piece test in a kind of welding process Wrong system, the system include sensor, and the sensor includes first sensor and second sensor, the first sensor and Whether second sensor is separately mounted to remove in frock and for the part in detecting tool；Also include controller, controller Including processor and trigger, the signal output part of first sensor and second sensor signal output part successively with door First signal input part is connected with secondary signal input, is connected with the signal output part of door with the signal input part of trigger, The signal output part of trigger is connected with the signal input part of processor, welding unit control end and the welding unit of processor Control end is connected.

After the welding of 4 wheel driven part is finished and shifted, first sensor or/and second sensor are normal bright state, then lead to Crossing and final signal being drawn with door and trigger, processor judges that sensor has adhered to welding slag, then processor is signaled to welding Unit, welding job suspend, and need the welding slag adhered on cleaning sensing.

In a kind of more preferred embodiment of the present utility model, controller also includes switch element, switch element string It is associated between the signal output part with door and the signal input part of trigger, control end and processor and the gate of switch element End processed is connected.

After the welding of 4 wheel driven part is finished and shifted, in order to prevent arc-welding station welding slag during welding from can drop on a sensor Face, processor control to be closed after sensor disconnects once again by break-make unit first, are conducive to having determined 4 wheel driven part Transfer, if now first sensor or/and second sensor are normal bright state, by drawing final letter with door and trigger Number, processor judges that sensor has adhered to welding slag, then processor is signaled to welding unit, and welding job suspends, and needs clear The welding slag adhered on reason sensor.

In a kind of more preferred embodiment of the present utility model, switch element includes relay, the output of relay The first end in loop is connected with the signal output part with door, the second end of the output loop of relay and the signal input of trigger End is connected, and the first end of the input circuit of relay is connected with power supply, the second end and the processor of the input circuit of relay It is connected with gate control end.

In a kind of preferred implementation of the present utility model, also including HMI display, the information input of HMI display End is connected with the HMI display outfans of processor, and the information output of HMI display is input into the HMI display of processor End is connected, display alarm information on HMI display.

If there is sensor adhesion welding slag, the display alarm information on HMI display reminds operator to note, if behaviour Author does not have found the warning message that the warning message in HMI display or operator are ignored in HMI display, i.e. processor is not received Warning message is processed to operator's determination that HMI display is transmitted, then 4 wheel driven welding will be unable to start.

In a kind of preferred implementation of the present utility model, trigger be reset type of priority SR flip and flop generators, institute State and be connected with the signal output part of door with the reset signal input of trigger.

In sum, as a result of above-mentioned technical proposal, the beneficial effects of the utility model are：This utility model is in original In the case of having station welding system, by changing circuit connection, detection 4 wheel driven part is realized.
