For example, the gap and surface difference of the door panels need to be tested. However, some existing testing equipment requires multiple clamping parts to press the automotive door panels together. During installation and disassembly, each clamping part needs to be adjusted one by one. This process involves many steps, is time-consuming, and has a significant impact on the testing efficiency of automotive door panels. In addition, the current equipment has relatively simple testing functions and is not easy to move, resulting in poor usability.

It includes a support frame, a movable component fixedly mounted below the support frame, an operating table fixedly mounted on the support frame, a storage box placed inside the operating table, a measuring frame fixedly mounted on the support frame, an observation plate fixedly mounted on one side of the measuring frame, a detection mechanism fixedly mounted on the other side of the measuring frame, and a toolbox fixedly mounted at the other end of the support frame. This utility model improves usability by incorporating a movable component at the bottom of the support frame, utilizing casters and support legs, and can meet the needs of different locations. Furthermore, the detection component on the measuring frame allows the door panel to be placed directly on the detection mechanism for measurement, resulting in a more comprehensive measurement and increased work efficiency for inspection personnel.

[0004] However, the above-mentioned inspection tool has the following problems in actual use: The support frame of the above-mentioned existing inspection tool is a metal frame with a steel pipe welded structure, and a support plate is fixedly installed on the support frame. One side of the support plate is fixedly connected to the measuring frame. This structure makes it difficult to perform inspection on the bottom side of the door panel after it is fixed because the door panel cannot be lifted. The operating area is small, which is not conducive to the inspection operation. Utility Model Content

The positioning seat 107 is connected to the connecting plate 104 by positioning pins and bolts. The bottom ends of both sides of the measuring frame 108 are connected to the positioning seat 107 by bolts. The mounting base 102 has a vertical mounting part on its rear side. The slide rail 109 is a linear slide rail and is fixed by countersunk bolts. The slider 110 is directly mounted on the slide rail 109 and is connected to one end of the stabilizing plate 111 by bolts. The other end of the stabilizing plate 111 is connected to the measuring frame 108. The rear side of the measuring frame 108 is a stepped cavity. The stabilizing plate 111 is connected to the bottom end face of its stepped cavity. The connecting device is used to fix the detection device. The detection device is used for the detection of the fixed structure of the automobile door panel.

[0025] Secondly, four mating posts 112 are fixedly connected to the measuring frame 108; the mating plate 113 is detachably connected to the mating posts 112. The mounting end of the mating post 112 is a spline end, and a locating pin hole and a threaded hole are provided annularly on the end face of the spline end. The measuring frame 108 is provided with a non-penetrating stepped spline cavity to facilitate the sliding insertion of the spline end of the mating post 112.

[0026] Then, the plurality of fixing blocks 114 are detachably connected to the mating plate 113; the measuring instrument 115 is disposed on both sides of the bottom of the mating plate 113. The size and installation position of the plurality of fixing blocks 114 can directly adopt the installation structure of fixing block No. 1, fixing block No. 2, fixing block No. 3 and limiting block disclosed in the prior art CN219474946U, which can be directly used to fix the car door panel. As prior art, it will not be described in detail here. The measuring instrument 115 is a three-axis measuring instrument, which can use lines to measure the gap and size of the car door panel to ensure the accuracy of the measurement data.

The T-shaped screw has an external hexagonal snap-fit ​​portion, and its external threaded end engages with the threaded drive of the T-shaped threaded cylinder. During movement, the bottom disc of the T-shaped screw does not contact the ground. When moved to the inspection location, the corresponding T-shaped screws can be rotated to allow their bottom discs to contact the ground, thus lifting the movable wheels 116 off the ground. At this time, the inspection fixture can be stably supported by the bottom discs of multiple T-shaped screws.

[0028] When using this utility model to solve the problem that existing inspection tools cannot be adjusted vertically after the car door panel is fixed, resulting in a small operating area at the bottom and hindering inspection operations, the inspection tool is moved to the measurement location by the moving mechanism. Then, the detection device is installed by the connecting device, and the car door panel is fixed to the detection device. It is fixed by the cooperation of multiple fixing blocks 114. Finally, the corresponding inspection can be performed. When it is necessary to inspect the bottom of the car door panel, the cylinder 103 is controlled to extend. After the cylinder 103 extends, it pushes the connecting plate 104 to move upward, thereby moving the positioning seat 107 upward, which in turn moves the measuring frame 108 upward. Finally, the car door panel is moved upward a certain distance, increasing the distance between its lower end and the top plane of the base frame 101, which is more conducive to subsequent inspection operations. This solves the problem that existing inspection tools cannot be adjusted vertically after the car door panel is fixed, resulting in a small operating area at the bottom and hindering inspection operations.
