DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Refer to Figures 1 - 3, a static elongation rate testing device for automotive interior fabric, comprising a base 1 and a moving plate 5. On the upper surface of the base 1, support columns 2 are symmetrically and fixedly connected on the left and right. On the upper surfaces of the two support columns 2, a top plate 3 is fixedly connected. The upper ends of the two support columns 2 penetrate and are fixedly connected with a fixing plate 4. On the lower surface of the fixing plate 4, a cylinder parallel clamp 6 is fixedly connected. On the lower surface of the fixing plate 4, a ranging sensor 7 is fixedly connected. The ranging sensor 7 is located on one side of the cylinder parallel clamp 6. On the side surfaces of the output ends of the cylinder parallel clamp 6, clamping blocks 8 are fixedly connected. The cylinder parallel clamp 6 will clamp the upper end of the automotive interior fabric, measure the deformation amount of the automotive interior fabric by detecting the moving distance of the moving plate 5, and then send the data to a display screen for display and recording.

[0020] On the upper surface of the moving plate 5, through holes 9 are symmetrically penetrated and opened on the left and right. The two support columns 2 are slidably connected in the through holes 9. On the left side of the upper surface of the moving plate 5, a first mounting plate 10 is fixedly connected. On the right side of the upper surface of the moving plate 5, a second mounting plate 11 is fixedly connected. On the right side surface of the second mounting plate 11, a servo motor 12 is fixedly connected. The output shaft of the servo motor 12 penetrates and is rotatably connected to the side surface of the second mounting plate 11. The output shaft of the servo motor 12 is fixedly connected with a bidirectional lead screw 13. The other end of the bidirectional lead screw 13 penetrates and is rotatably connected to the side surface of the first mounting plate 10. On the bidirectional lead screw 13, a first slider 14 and a second slider 15 are symmetrically threadedly connected. On the side surfaces of the first slider 14 and the second slider 15, two slide bars 16 are penetrated and slidably connected. The two ends of the two slide bars 16 are respectively fixedly connected to the side surfaces of the first mounting plate 10 and the second mounting plate 11. On the upper surface of the first slider 14, a first clamp 18 is fixedly connected. On the upper surface of the second slider 15, a second clamp 19 is fixedly connected. On the lower surface of the moving plate 5, a hook 17 is fixedly connected. The moving plate 5 is located below the fixing plate 4.

[0021] When the servo motor 12 drives the bidirectional lead screw 13 to rotate, the first slider 14 and the second slider 15 symmetrically arranged on the bidirectional lead screw 13 will move relatively until the two clamps above the two sliders cooperate to clamp the lower end of the automotive interior fabric. Finally, weights are added to the hook 17 to change the deformation of the clamped object. By setting a fixed clamp and a moving clamp, the two ends of the test piece can be clamped. Then, by applying pressure to the moving clamp end, the test piece is deformed. Then, the deformation length is recorded by the ranging sensor, and finally the result is calculated.

[0022] The functional principle of the present utility model can be described by the following operation method:

[0023] When it is necessary to detect the static elongation rate of the fabric for automotive interior parts, first start the cylinder parallel clamp 6 to clamp the upper end of the fabric for automotive interior parts, and then start the servo motor 12 to clamp the lower end of the fabric for automotive interior parts. At this time, the fabric for automotive interior parts is kept in a static condition. Then manually add weights to the hook 17 until the fabric for automotive interior parts deforms. When the fabric for automotive interior parts deforms, the moving plate 5 will move. At this time, the distance sensor 7 on the fixed plate 4 will measure the displacement of the moving plate 5 and send it to the display. Finally, the display will process the data to calculate the static elongation rate and display the result on the display. By setting the fixed clamp and the moving clamp, the two ends of the part to be detected can be clamped. Then, by applying pressure to the moving clamp end, the part to be detected is deformed. Then, the length of the deformation is recorded by the distance sensor. Finally, the result is calculated.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
