The model of the stress sensor 804 is HLC-300 and is used to detect stress changes. The stress sensor 804 is connected to a display through a wire to display the change value. The display is a prior art and will not be described in detail here. The bottom end of the stress sensor 804 is fixedly connected with a spring 803. The bottom end of the spring 803 is fixedly connected to the top of the measuring head 802. The measuring head 802 is supported on the surface of the sheet metal and transmits stress through the spring 803, thereby improving the accuracy of the sheet metal flatness detection. The mounting seat 801 is provided with a stress sensor 804. Two claws 12 are symmetrically fixed on the outer surface of 01, and an annular tube 9 is clamped inside the claws 12. The claws 12 are U-shaped and matched with the outer dimensions of the annular tube 9, which improves the stability of the installation of the annular tube 9. A plurality of nozzles 13 are evenly inserted at the bottom end of the annular tube 9, and a connecting pipe 14 is inserted at the top end of the annular tube 9 for connecting the pipeline to the ink outlet of the micro pump 5. By starting the micro pump 5, the ink inside the liquid storage barrel 6 can be pumped into the inside of the annular tube 9, and then sprayed onto the surface of the sheet metal from a plurality of nozzles 13, thereby improving the convenience of measuring marks.

[0023] A slot 10 is provided at the middle position of the base 1, and a limiting assembly 11 is provided at the inner bottom of the slot 10. The limiting assembly 11 includes a mounting plate 1101 rotatably connected to the inside of the slot 10 for placing sheet metal.

The waste barrel 15 closes the top of the liquid storage barrel 6, thereby improving the stability of the liquid storage barrel 6 in storing ink.

[0025] Working principle: When using this kind of gauge for detecting the flatness of sheet metal, the operator first connects an external power supply, places the sheet metal on the surface of the mounting plate 1101, and abuts the limit frame 1103 against the side wall of the sheet metal. Then, the limit frame 1103 and the mounting plate 1101 are threadedly connected in sequence by bolts, thereby improving the stability of the sheet metal fixation, so that the measuring head 802 is pressed on the surface of the sheet metal. When the spring 803 is compressed, the elastic force can be transmitted to the stress sensor 804, so that the measurement can be achieved according to the stress change detected by the stress sensor 804. By starting the cylinder 4, the slider 3 can be pushed to move horizontally, thereby changing the position of the measuring head 802, which is convenient for multiple measurements. By starting the servo motor to drive the mounting plate 1101 to rotate, the angle of the sheet metal can be changed to measure the flatness. When the measurement error is large and needs to be marked, the ink inside the liquid storage barrel 6 can be pumped to the inside of the annular tube 9 by starting the micro pump 5, and then sprayed from a plurality of nozzles 13 to the surface of the sheet metal, thereby improving the convenience of measurement and marking.

[0026] Secondly, the waste barrel 15 can be threadedly connected to the top of the liquid storage barrel 6 by rotating the end cover 16. The waste barrel 15 closes the top of the liquid storage barrel 6, which improves the stability of the liquid storage barrel 6 in storing ink. The hole groove 17 runs through the waste barrel 15 for ventilation to facilitate balancing the internal air pressure of the liquid storage barrel 6. The liquid storage barrel 6 is made of transparent plastic material for easy observation of the liquid level. Rotating the end cover 16 facilitates the replenishment of marking ink.
