Technical Field
[0001] The utility model belongs to the technical field of inspection tools, and in particular relates to an inspection tool for an automobile door trim panel. Background Art
[0002] Automobile door interior panels are an important component of the inner side of the door. They not only beautify the interior environment of the car, but also have a variety of practical functions. During the production process of automobile door interior panels, they need to be sampled and inspected. Inspection fixtures are needed during the inspection process. The inspection fixtures of door interior panels need to clamp and fix the door trim panels when inspecting them. However, in the prior art, it is difficult to control the clamping force of the clamp used to clamp the door trim panels. Moreover, since the shapes of door interior panels are often irregular, the clamps are not suitable for clamping door interior panels of different shapes. Utility Model Content
[0003] In view of the above problems, the purpose of the utility model is to provide an automobile door trim inspection fixture, the clamping plates of the device can adapt to door trims of different shapes, ensure the fit between the clamping plates and the surface of the door trims, thereby ensuring the clamping stability, and at the same time can appropriately control the clamping force of the clamping plates, so that the clamping plates can maintain clamping on the door trims, but will not clamp too tightly to cause deformation of the door trims and affect the inspection effect.
[0004] To achieve the above objectives, the utility model provides the following technical solutions: an automobile door trim inspection fixture, comprising a detection platform, a detection device is provided on the top of the detection platform, an adjustment slide is provided on the top of the detection platform, a clamp mechanism is slidably installed inside the adjustment slide, the clamp mechanism comprises a first slider slidably installed inside the adjustment slide, a first adjustment guide rail is installed on the top of the first slider, a second slider is slidably installed inside the first adjustment guide rail and a first screw rod is rotatably installed, a first servo motor is installed on the top of the first adjustment guide rail, and a third slider is installed on the side of the second slider. The third slider is slidably installed inside the second adjusting guide rail, and a second screw rod is rotatably installed inside the second adjusting guide rail. A second servo motor is installed at one end of the second adjusting guide rail, and the other end of the second adjusting guide rail is connected to the fixture mounting frame. A sliding rod and an auxiliary guide sliding rod are slidably and inserted on the fixture mounting frame, and one end of the sliding rod and the auxiliary guide sliding rod are connected to a rotatable clamping mechanism.

A pressure sensor is installed on the fixture mounting frame, and the pressure sensor is in contact with the pressure plate.
[0005] The beneficial effects of the utility model are as follows: when the device is used, the position of the clamp can be adjusted according to the size and thickness of the automobile door trim to be tested, and the number of clamp mechanisms can be conveniently adjusted through the adjustment slides running through both ends. During testing, the door trim to be tested is placed on the testing table, and then the second servo motor is controlled to drive the second screw rod to rotate, and the second adjustment guide rail is driven to translate through the spiral transmission between the second screw rod and the third slider, thereby driving the clamp to move toward the door trim.

The second servo motor is controlled to drive the second screw rod to rotate, and through the spiral transmission between the second screw rod and the third slider, the second adjustment guide rail is driven to translate, thereby driving the splint to move toward the door trim.
[0015] To adapt the clips to different door trim shapes:

During testing, the door trim to be tested is placed on the testing table 1, and then the second servo motor 18 is controlled to drive the second screw rod 17 to rotate, and the second adjustment guide rail 15 is driven to translate through the spiral transmission between the second screw rod 17 and the third slider 16, thereby driving the clamp 30 to move toward the door trim. When the clamp 30 contacts the door trim, the first pin seat 26 and the first pin shaft 27 cooperate to make the clamp 30 rotate up and down along with the shape of the door trim.

The second servo motor 18 is controlled to drive the second screw rod 17 to rotate. Through the spiral transmission between the second screw rod 17 and the third slider 16, the second adjustment rail 15 is driven to translate, thereby driving the clamping plate 30 to move toward the door trim.
