DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings of the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] Example 1

[0028] Refer toFigures 1-2 A testing device includes: a workbench 1 and a top seat 3 fixedly installed on the top of the workbench 1. A frame 2 is provided above the workbench 1, and a groove 4 is provided on the top of the frame 2 for placing a skylight.

[0029] The top of the workbench 1 is equipped with a fixing mechanism for limiting and fixing the frame 2 and the skylight. The fixing mechanism includes multiple support columns 9 fixedly installed on the top of the workbench 1. The bottom of the frame 2 has multiple grooves, and the tops of the multiple support columns 9 are located inside the multiple grooves. The frame 2 can be positioned by the cooperation between the support columns 9 and the grooves.

[0030] Reference Figures 2-3 The fixing mechanism also includes a side plate 8 that is slidably disposed on one side of the support column 9. A plug plate 10 is fixedly disposed on the top of the side plate 8. Multiple slots 6 are opened on the side of the frame 2. Multiple plug plates 10 are respectively inserted into the interior of multiple slots 6 to fix the frame 2.

[0031] The fixing mechanism also includes an outer plate 13 located on one side of the insert plate 10. A connecting frame 7 is fixedly installed on the top of the insert plate 10. A sliding frame 12 is fixedly installed at one end of the connecting frame 7, and the sliding frame 12 is slidably sleeved on the outer wall of the outer plate 13. Multiple insertion holes 5 are opened on the side wall of the frame 2. One end of the outer plate 13 is inserted into the interior of the insertion hole 5 for additional fixing of the frame 2 when fixing the skylight.

[0032] Specifically, when the side plate 8 moves, one end of the insert plate 10 will be inserted into the slot 6 to fix the frame 2. At the same time, the insert plate 10 will move the slide frame 12 through the connecting frame 7, so that one end of the slide frame 12 is also inserted into the socket 5 for auxiliary fixation.

[0033] Reference Figure 4 Two connecting bars 20 are slidably arranged on the top of the workbench 1. A bidirectional threaded rod 19 is rotatably arranged on the top of the workbench 1, and the two connecting bars 20 are respectively threaded onto the two ends of the outer wall of the bidirectional threaded rod 19. A connecting rod 11 is fixedly arranged on one side of the side plate 8. One end of the connecting rod 11 slides through the support column 9 and is fixedly arranged with the connecting bar 20.

[0034] Specifically, by rotating the bidirectional threaded rod 19, the two connecting bars 20 can be driven to move in opposite directions. The connecting bars 20 drive the side plate 8 to move through the connecting rod 11, thereby achieving the effect of fixing the frame 2.

[0035] A limit rod is fixedly installed at the bottom of the top seat 3, and a second threaded rod 17 is rotatably installed thereon. A motor connected to the second threaded rod 17 is fixedly installed at the top of the top seat 3. The mounting plate 22 is slidably sleeved on the outer wall of the limit rod and threadedly sleeved on the outer wall of the second threaded rod 17. The sensor 21 is a contact displacement sensor. After its probe contacts the surface of the sunroof, it converts the deformation into an electrical signal output.

[0036] Specifically, the drive motor rotates the second threaded rod 17, thereby moving the mounting plate 22 and the sensor 21 at the bottom downwards to detect curvature. The sensor 21 can be the existing TC202-Xiongqiang-98 contact sensor. After contacting the surface of the sunroof, it can sense minute deformations and convert them into electrical signals. The principle is that after direct contact with the sunroof glass surface, due to the curvature change of the glass surface, the probe will generate a minute displacement along the normal direction. The probe displacement is transmitted to the internal components of the sensor, causing changes in electrical parameters such as resistance, inductance, or capacitance. Then, it is converted into a voltage or current signal proportional to the displacement, which is processed by the computer analysis system to achieve the detection effect.

[0037] A mounting plate 22 is provided below the top seat 3. An inclined panel 18 is fixedly provided on the side wall of the mounting plate 22 by a bracket. The inclined panel 18 cooperates with the outer plate 13 on the same side. The same compression spring 15 is provided between the slide frame 12 and the outer plate 13. The two ends of the compression spring 15 abut against the outer plate 13 and the slide frame 12 respectively through spring seats.

[0038] Specifically, when the mounting plate 22 moves downward, it will cause the inclined panel 18 to move as well. When the inclined panel 18 moves, it will touch the outer panel 13, thereby pushing the outer panel 13 further inward, so that the inner panel 16 passes through the socket 5 and abuts against the skylight, thus fixing the skylight.

[0039] This application can be used in the field of automotive parts testing, or in other fields applicable to this application.

The inner plate 16 is threadedly sleeved on the outer wall of the first threaded rod 14.

[0042] Specifically, by rotating the No. 1 threaded rod 14, the inner plate 16 is driven to slide along the inside of the outer plate 13, adjusting the contact position between the inner plate 16 and the skylight to adapt to the clamping requirements of skylights of different sizes.

[0043] However, as known to those skilled in the art, the working principles and wiring methods of the sensor and the motor are common, which are all conventional means or common general knowledge, and will not be described here again.
