[0024] like Figure 1 As shown, a sensor probe 13 and a data transmission probe 11 form a set of displacement sensors, and three sets of displacement sensors are evenly distributed on the round base 14 with an interval of 180°. The sensor probes 13 are respectively plugged into the round base 14, and the round base 14 is clamped and fixed by a clamping block. The fixed side plate 18 is fixedly connected to the measuring base plate 15, the measuring base plate 15 is welded to the moving plate 10, the guide rod 21 is fixedly connected to the fixed side plate 18, the outer clamping block 7 is fixedly installed with the moving plate 10 by screws, the outer clamping block 7 is slidably connected to the middle slider 9, the middle slider 9 is fixedly connected to the fixed plate 8, the fixed plate 8 is welded to the mounting plate 6, and the mounting plate 6 is fixedly connected to the frame 5 by screws.

A calibration side plate 4 is provided on the side bottom plate 3, and the calibration side plate 4 is fixedly connected to the side bottom plate 3. A moving block 16 is provided in front of the calibration side plate 4, and a circular through hole 17 is provided on the moving block 16. A calibration cylinder 20 is provided at the bottom of the top of the calibration side plate 4, and a measuring cylinder 19 is provided at the bottom of the moving block 16.

Through the contact between the three sensor probes 13 and the data transmission probe 11, the upper and lower heights of the contact displacement sensor are calibrated to ensure the accuracy of the contact displacement sensor in measuring the flatness of the workpiece and reduce the measurement error generated by the machine. Through the setting of the spring 23 and the pad 22, when the moving block 16 moves up and touches the pad 22, the pad 22 is pushed up. At this time, the spring 23 is compressed. The setting of the spring 23 buffers the contact between the moving block 16 and the pad 22, thereby preventing the moving block 16 from colliding with the pad 22 due to the operator's misoperation, thereby causing damage to the sensor probe 13.
