In this embodiment, the 2D sensors 7 are all commercially available products and are connected to an external host computer. There are two 2D sensors 7. One of the 2D sensors 7 is used to measure the position of the surface A0009 to be detected on the product 0001 to be detected, and the other 2D sensor 7 is used to measure the position of the surface B 0010 to be detected on the product 0001 to be detected. The two 2D sensors 7 are symmetrically arranged on both sides of the gauge 3 respectively, so as to accurately measure respectively and facilitate subsequent analysis and calculation. Each 2D sensor 7 is installed on the bottom surface of the floating seat 2 through a sensor mounting plate 14 and screws. In this embodiment, the external host computer compares the received information fed back by the ranging sensor 6 and the two 2D sensors 7 with the calibration value of the gauge 3, and obtains the distance between the surface A 0009 to be detected and the plane where the top surface of the upper slider 0004 is located, the distance between the surface B 0010 to be detected and the plane where the top surface of the upper slider 0004 is located, the distance between the surface A 0009 to be detected and the surface C0011 to be detected, the distance between the surface B 0010 to be detected and the surface C 0011 to be detected, automatically records them for reading, and interprets the measurement results, and can also be set to automatically upload data.

[0043] Specifically, as Figure 6As shown in the figure, in this embodiment, a pressure sensor 12 is provided on the upper part of the floating seat 2. The pressure sensor 12 is a commercially available product and is connected to an external host computer. During measurement, the detection end of the pressure sensor 12 abuts against the bottom surface of the cylinder mounting plate 4.

The pressure sensor 12 is provided to detect the pressure between the floating seat 2 and the cylinder mounting plate 4 when the abutting bumps 301 of the gauge 3 are respectively pressed on the top surfaces of the corresponding upper sliders 0004. When the pressure value detected by the pressure sensor 12 exceeds the preset value, the mounting frame 1 stops feeding and moves away from the product 0001 to be detected to avoid excessive pressure on the product 0001 to be detected and causing damage. The setting of the disc spring 13 plays a buffering and protecting role for the detection end of the pressure sensor 12 and ensures the service life of the pressure sensor 12.

[0046] When the two abutting bumps 301 are respectively in contact with the top surfaces of the corresponding upper sliders 0004, the gauge body 303 is located between the two upper sliders 0004 and at the same time between the two middle sliders 0003. The lower slider 0002 on the product 0001 to be detected is stuck between the two lower positioning blocks 304. Each middle slider 0003 on the product 0001 to be detected is respectively in contact with the adjacent lower guide block 306, and each upper slider 0004 on the product 0001 to be detected is respectively in contact with the adjacent upper guide block 307.

In this embodiment, each lower positioning block 304 is respectively provided with a guide groove that fits with the guide protrusion on the adjacent lower slider 0002, which can stably hold the lower slider 0002 between the two lower positioning blocks 304. The cooperative setting of the lower guide block 306, the upper guide block 307, and the guide plate 305 that can be inserted into the chute A and chute B on the product 0001 to be detected can accurately position the movement of the gauge body 303.

[0047] Specifically, as Figure 11 and Figure 12 shown, in this embodiment, the pressing mechanism 8 includes a pressing mechanism mounting plate 801, a pressing shaft sleeve 802, a pressing shaft 803, an end cap 804, a spring B 805, and a spring gland 806.

The inner side of the pressing shaft sleeve 802 is provided with a stepped hole for installing the pressing shaft. Both the upper and lower ends of the stepped hole for installing the pressing shaft are open and there is a stepped surface inside. The spring gland 806 is installed at the upper opening of the stepped hole for installing the pressing shaft by threads. The end cap 804 is located in the stepped hole for installing the pressing shaft. The bottom surface of the end cap 804 abuts against the stepped surface of the stepped hole for installing the pressing shaft, and the top surface abuts against the lower end of the spring B 805. The upper end of the spring B 805 abuts against the bottom surface of the spring gland 806. The upper end of the pressing shaft 803 passes through the lower opening of the stepped hole for installing the pressing shaft and is connected to the end cap 804 by screws. The lower end surface of the pressing shaft 803 abuts against the top surface of the measuring block 0006 on the product 0001 to be detected. Through the cooperative setting of the pressing mechanism mounting plate 801, the pressing shaft sleeve 802, the pressing shaft 803, the end cap 804, the spring B 805, and the spring gland 806, when the pressing shaft 803 presses on the top surface of the measuring block 0006 on the product 0001 to be detected, the spring B 805 plays a buffering role to avoid damaging the top surface of the measuring block 0006 on the product 0001 to be detected.

[0048] Working principle:

[0049] When testing the product 0001 to be detected, the mounting bracket 1 moves towards the direction where the product 0001 to be detected is located to a specified position, so that the gauge body 303 is gradually inserted between the two upper sliders 0004 and between the two middle sliders 0003; the two abutting bumps 301 are respectively abutted against the top surfaces of the corresponding upper sliders 0004, the pressing mechanism 8 presses on the top surface of the measuring block 0006 on the product 0001 to be detected from above, the spring A10 compresses to buffer the floating seat 2. After determining that the two abutting bumps 301 are respectively pressed against the top surfaces of the corresponding upper sliders 0004, the mounting bracket 1 stops feeding at this time; the distance between the distance measuring sensor 6 and the surface C 0011 to be measured on the product 0001 to be detected is detected by the distance measuring sensor 6, one 2D sensor 7 measures the position of the surface A 0009 to be measured on the product 0001 to be detected, and the other 2D sensor 7 measures the position of the surface B 0010 to be measured on the product 0001 to be detected. The distance measuring sensor 6 and the two 2D sensors 7 respectively feedback the measured information to the external host computer, and the required values are obtained through calculation; after the measurement is completed, the mounting bracket 1 returns to the initial position.
