Description

Technical Field

[0001] The present application relates to the technical field of automobile parts testing, and in particular to a strength testing device for automobile interior composite panels. Background Art

[0002] Composite panels are usually used in car interiors. Composite panels usually have good wear resistance, corrosion resistance, scratch resistance and other properties. These characteristics enable interior components to resist daily wear and erosion from the external environment during use, thereby extending service life, reducing replacement frequency, and lowering maintenance costs for car owners. Composite panels need to undergo strength testing before use and can only be put into use after passing the test.

[0003] Patent No. CN 217931153 U discloses a strength testing device for automobile interior composite panels, including a base, a support frame, a protrusion, a pressure plate and a sliding plate. By setting the pressure plate, two sets of sliding plates drive the pressure plate to move relative to each other. Because the pressure plate is set at an angle, when the pressure plate moves relative to each other, it can gradually apply pressure from both ends of the automobile interior composite panel. When the pressure plate applies pressure, there will be a force to lift the automobile interior composite panel upward. At this time, the middle part of the automobile interior composite panel will contact the pressure protrusion, and the pressure protrusion will rest against the middle part of the automobile interior composite panel. The automobile interior composite panel is pressurized by the pressure plate, thereby performing strength testing on the automobile interior composite panel.

[0004] However, in use, there are the following defects:

[0005] Although an inclined pressure plate is used to gradually extrude the interior composite panel, during the extrusion process, the interior composite panel gradually bends and its two ends gradually fit into the surface of the pressure plate. It may suddenly slip out of the surface of the pressure plate, resulting in extrusion failure. In addition, the interior composite panel may break during the extrusion process and may suddenly pop out and injure the staff. Utility Model Content

[0006] The purpose of the present application is to provide a strength testing device for automotive interior composite panels, which solves the problem proposed in the background art that although an inclined pressure plate is used to gradually extrude the interior composite panel, during the extrusion process, the interior composite panel gradually bends, and its two ends gradually fit into the surface of the pressure plate, and may suddenly slip out of the surface of the pressure plate, thereby causing extrusion failure, and the interior composite panel may break during the extrusion process and suddenly jump out to injure the staff.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A strength detection device for automobile interior composite panels, comprising a base, a lifting rod, a support frame, a pressure plate and a bonding plate, wherein one side of the top end of the base is fixedly connected to a side plate, and a side groove is laterally provided on the surface of the side plate, and the inner side of the side groove is rotatably connected to a No. 1 bidirectional screw rod, and both sides of the surface of the No. 1 bidirectional screw rod are threadedly connected to a No. 1 threaded block, and a connecting rod is fixedly welded to the outer wall of the No. 1 threaded block, and the other end of the connecting rod is rotatably connected to a rotating drum, the side wall surface of the rotating drum is fixedly connected to the protrusion on the surface of the pressure plate, and the other side surface of the side wall of the rotating drum is provided with a plurality of limiting holes in a circular array. The outer wall of the connecting rod on one side of the rotating drum is threadedly connected to a limiting bolt, and an adjusting slot is vertically opened on the surface of the other side of the pressure plate, and the inner side of the adjusting slot is rotatably connected to a No. 2 two-way screw rod, and both sides of the surface of the No. 2 two-way screw rod are threadedly connected to a No. 2 threaded block, and the outer wall of the No. 2 threaded block is fixedly connected to the limiting plate. The two ends of the bottom of the support frame are respectively fixedly connected to the top two sides of the base, and the two sides below the top of the support frame are fixedly connected to the sleeve, and the bottom of the sleeve is movably sleeved with a lifting rod, and the bottom of the lifting rod is fixedly connected to the top of the bonding plate through a rotating shaft, and the inner top of the sleeve is fixedly connected to a spring.

[0008] In this technical solution, the rotating drum, pressure plate and limit plate can adapt to the detection of different composite plates. The two ends of the composite plate are placed between the limit plates on the surfaces of the pressure plates on both sides, and then the handle is twisted to drive the No. 2 bidirectional screw to rotate, so that the No. 2 threaded block brings the limit plate closer in the adjustment groove, thereby constraining and limiting the two ends of the composite plate. Then, after the drive motor is started, it drives the No. 1 bidirectional screw to rotate, so that the No. 1 threaded block moves laterally with the connecting rod and the pressure plate, thereby applying pressure to the pressure plate and starting to detect the pressure plate. The rotating drum can drive the pressure plate to adjust the angle through the limit hole and the limit bolt, which adapts to the constraint and limitation of composite plates with different degrees of inclination and bending. The lifting plate will continue to rise until it contacts the spring inside the sleeve, and the spring will remove the force of the composite plate jumping upward during the extrusion process, thereby avoiding the composite plate from flying out directly due to excessive elastic force and injuring the staff, thereby improving the safety and stability of the device.

[0009] As an optional solution of the technical solution of the present application, a threaded rod is threadedly connected through the center of the top of the support frame, a pressure sensor is fixedly connected to the bottom of the threaded rod, and a power supply is fixedly connected to the top of the support frame on one side of the threaded rod.

[0010] As an optional solution of the technical solution of the present application, the outer wall of the side plate facing the right end of the No. 1 bidirectional screw is fixedly connected to a drive motor, and the outer end of the transmission shaft of the drive motor is fixedly connected to the right end of the No. 1 bidirectional screw.

[0011] As an optional solution of the technical solution of the present application, the top end of the No. 2 bidirectional screw rod passes through the adjustment slot and is fixedly connected to the handle.

[0012] As an optional solution of the technical solution of the present application, the size of the limiting hole is consistent with that of the limiting bolt, and the inner side of the limiting hole is provided with a thread consistent with the surface of the limiting bolt.

[0013] As an optional solution of the technical solution of the present application, the limiting plate is perpendicular to the surface of the pressure plate, and the laminating plate remains flush with the base when there is no contact.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The present application can adapt to the detection of different composite plates through the rotating drum, pressure plate and limit plate. The two ends of the composite plate are placed between the limit plates on the surfaces of the pressure plates on both sides. The handle is twisted to drive the No. 2 bidirectional screw to rotate, so that the No. 2 threaded block brings the limit plates closer in the adjustment groove, and the two ends of the composite plate are constrained and limited. Then, after the driving motor is started, it drives the No. 1 bidirectional screw to rotate, so that the No. 1 threaded block moves laterally with the connecting rod and the pressure plate, thereby applying pressure to the pressure plate and starting to detect the pressure plate. The rotating drum can drive the pressure plate to adjust the angle through the limit hole and the limit bolt, which adapts to the constraint and limit requirements of composite plates with different inclinations and bending degrees, avoids the composite plate from slipping out during the pressure process, and improves the detection practicality of the device.

[0016] 2. The present application can protect the composite plate through the sleeve tube, lifting rod, spring and bonding plate. The composite plate will bend and bulge upward after being squeezed. At this time, the bonding plate will contact the surface of the composite plate and fit together. As the composite plate gradually bends and rises, the lifting plate will gradually slide into the sleeve tube. If the composite plate suddenly breaks, it will jump upward. At this time, the lifting plate will continue to rise until it contacts the spring inside the sleeve tube. During the squeezing process, the spring will remove the force of the composite plate jumping upward, avoiding the excessive elastic force of the composite plate directly flying out and injuring the staff, thereby improving the safety and stability of the device.

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a strength detection device for automobile interior composite panels includes a base 1, a lifting rod 9, a support frame 3, a pressure plate 18 and a bonding plate 11. A threaded rod 4 is threadedly connected to the center of the top of the support frame 3, and a pressure sensor 5 is fixedly connected to the bottom of the threaded rod 4. A power supply 6 is fixedly connected to the top of the support frame 3 on one side of the threaded rod 4. The pressure sensor 5 can adjust its height under the drive of the threaded rod 4 to adapt to the bending limit height of different types of composite panels.

[0026] like Figure 1 and Figure 3As shown, the two ends of the bottom of the support frame 3 are respectively fixedly connected to the two sides of the top of the base 1, and the two sides below the top of the support frame 3 are fixedly connected with sleeve pipes 7. The bottom of the sleeve pipe 7 is movably sleeved with a lifting rod 9. The bottom of the lifting rod 9 is fixedly connected to the top of the bonding plate 11 through a rotating shaft 10, and the inner top of the sleeve pipe 7 is fixedly connected with a spring 8. The spring 8 can remove the rapid rising force of the lifting rod 9 and the bonding plate 11, thereby avoiding the breakage of the composite plate and causing rapid pop-up to injure the staff.

[0027] like Figure 2 As shown, a side plate 2 is fixedly connected to one side of the top of the base 1, and a side groove 12 is horizontally opened on the surface of the side plate 2. The inner side of the side groove 12 is rotatably connected to a No. 1 bidirectional screw rod 13, and the outer side wall of the side plate 2 facing the right end of the No. 1 bidirectional screw rod 13 is fixedly connected to a drive motor 131. The outer end of the transmission shaft of the drive motor 131 is fixedly connected to the right end of the No. 1 bidirectional screw rod 13, and both sides of the surface of the No. 1 bidirectional screw rod 13 are threadedly connected to a No. 1 threaded block 14, and the outer side wall of the No. 1 threaded block 14 is fixedly welded with a connecting rod 15.

[0028] like Figure 1 and Figure 4 As shown, the other end of the connecting rod 15 is rotatably connected to the rotating drum 16, and the side wall surface of the rotating drum 16 is fixedly connected to the protrusion on the surface of the pressure plate 18. The other side surface of the side wall of the rotating drum 16 is provided with a plurality of limiting holes 161 in a circular array. The outer wall of the connecting rod 15 on one side of the rotating drum 16 is threaded with a limiting bolt 17. The size of the limiting hole 161 is consistent with the limiting bolt 17, and the inner side of the limiting hole 161 is provided with a thread consistent with the surface of the limiting bolt 17. After the limiting bolt 17 is screwed into the corresponding limiting hole 161, the rotating drum 16 will be kept stationary, so that the pressure plate 18 maintains its current tilt state, which adapts to the placement requirements of composite panels with different tilt and bending degrees.

[0029] like Figure 5 As shown, an adjustment slot 19 is vertically opened on the other side surface of the pressure plate 18, and a No. 2 bidirectional screw rod 20 is rotatably connected to the inner side of the adjustment slot 19. The top end of the No. 2 bidirectional screw rod 20 passes through the adjustment slot 19 and is fixedly connected to the handle 23. Both sides of the surface of the No. 2 bidirectional screw rod 20 are threadedly connected with a No. 2 threaded block 21. The outer wall of the No. 2 threaded block 21 is fixedly connected to a limit plate 22. The limit plate 22 is perpendicular to the surface of the pressure plate 18, and the bonding plate 11 remains parallel to the base 1 when there is no contact. The limit plate 22 constrains and limits the two ends of the composite plate from the upper and lower sides, thereby preventing the composite plate from popping out when pressure is applied.

[0030] In actual use, the two ends of the composite plate are placed between the limit plates 22 on the surfaces of the pressure plates 18 on both sides, and then the handle 23 is twisted to drive the No. 2 bidirectional screw 20 to rotate, so that the No. 2 threaded block 21 is brought close to the limit plates 22 in the adjustment groove 19, thereby constraining the two ends of the composite plate. Then, after the driving motor 131 is started, it drives the No. 1 bidirectional screw 13 to rotate, so that the No. 1 threaded block 14 moves laterally with the connecting rod 15 and the pressure plate 18, thereby applying pressure to the pressure plate 18 and starting to detect the pressure plate 18. The rotating drum 16 can drive the pressure plate 18 to adjust the angle through the limit hole 161 and the limit bolt 17, which adapts to the constraint and limit requirements of composite plates with different inclinations and bending degrees, avoids the composite plate from slipping out during the pressure process, and improves the detection practicality of the device. Different composite plates have different strengths and different degrees of bending. The height of the pressure sensor 5 can be changed by adjusting the threaded rod 4 to meet the detection needs of different types of composite plates. At the same time, the composite plate can be protected by the sleeve tube 7, lifting rod 9, spring 8 and bonding plate 11. The composite plate will bend and bulge upward after being squeezed. At this time, the bonding plate 11 will contact the surface of the composite plate and fit together. As the composite plate gradually bends and rises, the lifting plate will gradually slide into the sleeve tube 7. If the composite plate suddenly breaks, it will jump upward. At this time, the lifting plate continues to rise until it contacts the spring 8 inside the sleeve tube 7. During the squeezing process, the spring 8 will remove the force of the composite plate jumping upward, avoiding the excessive elastic force of the composite plate directly flying out and injuring the staff, thereby improving the safety and stability of the device.
