[0017] like Figures 1-3 As shown, a car seat frame assembly inspection fixture includes a fixing plate 1, a support device, a positioning device, and a clamping device. The fixing plate 1 is installed on the upper end face of the support frame 2. Each of the four legs below the support frame 2 is equipped with a pulley 3 to facilitate the movement of the support frame 2 and the fixing plate 1. Four support devices, positioning devices, and clamping devices are provided and installed on the fixing plate 1. The clamping device is located beside the support device. The support device includes a support column 4 and a support block 5. The support block 5 is installed on the support column 4. During inspection, the car seat frame assembly is placed on the support block 5. The positioning device includes a positioning column 6, a positioning arm 7, and a positioning pin 9. The positioning column 6 is installed on the front and rear sides of the car seat frame assembly. The positioning column 6 has a groove, and a support rod is installed in the groove. The positioning arm 7 has a sliding groove 71 in the middle, and the support rod is installed in the sliding groove 71. The positioning arm 7 is slidably mounted on the positioning column 6 through the cooperation of the sliding groove 71 and the support rod. The slide rail 8 of the car seat frame assembly is hollow inside, with openings at both the front and rear ends. When positioning is required, the positioning arm 7 is moved and extends into the cavity through the opening. The support column 4 and the support block 5 are provided with through holes for the positioning pin 9 to pass through. The lower end face of the slide rail 8 is provided with positioning holes. There are four positioning holes, and their positions correspond to the installation positions of the positioning pin 9. The positioning pin passes through the through holes on the support column 4 and the support block 5 and can be pulled out and inserted into the positioning hole of the slide rail 8. A spring or elastic component is provided in the part of the through hole to facilitate the pulling and resetting of the positioning pin 9. This is existing technology and will not be described in detail here.

[0018] The clamping device includes a clamping column 10 and a clamp 11. The clamp 11 is mounted on the clamping column 10, and the clamping jaws of the clamp 11 are set to face the positioning arm 7.
