Detailed ways

In order to make the technical means realized by the utility model, creation features, purpose and effect easy to be understood, the utility model is further elaborated below.

Refer to the oil dipstick length and O-ring detection tooling shown in Figures 1 to 6, including a frame 100 on which an NG box 200, an oil dipstick length detection unit 300, an O-ring detection unit 400 and a pressing Agency 500. The oil dipstick length detection unit 300 , the O-ring detection unit 400 and the pressing mechanism 500 are connected to the PLC control device 600 . The PLC control device 600 is connected with the man-machine interface 700, and the PLC control device 600 is also connected with the alarm device.

The oil dipstick length detection unit 300 includes a zero calibration mechanism 310 and a length detection component 320 , and the zero calibration mechanism 310 and the length detection component 320 are connected to the frame 100 . The length detection element 320 includes a length detection head 321 and a length detection cylinder 322 that drives the length detection head 321 to slide. The length detection cylinder 322 is connected with the PLC control device 600 . Specifically, when the oil dipstick length detection unit 300 detects the length of the oil dipstick, the length detection head 321 and the length detection cylinder 322 are in the waiting state at this time. After the oil dipstick is placed on the frame 100 and fixed, it is controlled by the PLC control device 600 The length detection cylinder 322 drives the length detection head 321 to slide towards the end of the dipstick for detection. The length detection head 321 has an initial value when it is in the working state. When the length detection head 321 moves a certain distance under the action of the length detection cylinder 322, it touches To the end of the oil dipstick, the length of the oil dipstick can be obtained by calculating the moving distance and the standard reference value.
