A car is composed of numerous parts. One aspect of testing automotive parts is the bending strength of rod-shaped automotive components.

[0003] For example, patent announcement CN217954131U discloses a device for testing the bending strength of automotive parts: it includes a base plate, with a telescopic hydraulic rod at the upper end of the base plate. The device is characterized by having two horizontally spaced support rods fixedly connected to the upper end of the base plate, horizontally arranged positioning rods fixedly connected to the opposite ends of the two support rods, and a measuring rod parallel to the positioning rods fixedly connected to the opposite ends of the two support rods. The positioning rods and support rods are laterally slidably fitted with two spaced sliders. Each slider has a support block fixedly connected to its upper end, and the opposite ends of the two support blocks each have horizontally arranged V-shaped grooves. Each support block has an upper pressing device fixedly connected to its upper end. The outer edge of the positioning rod has several evenly distributed positioning holes along its length.

[0004] In the aforementioned patent, the inventor believes that although the patent satisfies the adaptability of the length and diameter limit fixation of the cylindrical automobile parts when in use, the automobile parts need to be manually fixed each time when the automobile parts are subjected to bending resistance testing. This fixing method is inefficient and reduces the efficiency of automobile parts testing. Utility Model Content

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. The present invention relates to a testing device for processing automotive parts. By setting a pressure plate on one side of an automotive part support, when a hydraulic device drives a bending test component to apply pressure to a cylindrical automotive part for bending resistance testing, the descent of the pressure plate can be movably connected to a pressing transmission mechanism.

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See also Figures 1-4 This utility model provides a testing device for automotive parts processing, including a support plate 1, a bidirectional drive unit 2 on the support plate 1, a pair of automotive parts supports 3 on the bidirectional drive unit 2, the automotive parts supports 3 being used to place cylindrical automotive parts, a bracket 4 fixedly connected to the support plate 1, a hydraulic device 41 fixedly connected to the bracket 4, the hydraulic device 41 being a hydraulic rod, and a bending test component 5 for testing the bending strength of automotive parts being provided at the output end of the hydraulic device 41.

[0026] The bidirectional drive unit 2 includes a bidirectional lead screw 21, which is rotatably connected to one side of the support plate 1. A rotary motor 22 is fixedly connected to one side of the support plate 1, and the output end of the rotary motor 22 is fixedly connected to one end of the bidirectional lead screw 21. A pair of guide blocks 23 are threadedly connected to the bidirectional lead screw 21. A slide rail 24 is fixedly connected to one side of the support plate 1, and the guide blocks 23 are slidably connected to the slide rail 24. The automotive component support 3 is fixedly connected to the guide blocks 23.

[0027] Specifically, the rotary motor 22 is started by an external controller. With the slide rail 24 providing sliding guidance for a pair of guide blocks 23, the output rotation of the rotary motor 22 can cause the pair of guide blocks 23 on the bidirectional lead screw 21 to move closer or further apart. This can adjust the spacing between a pair of automotive component supports 3 to meet the length adaptability requirements of the bending resistance test of the cylindrical automotive component.

[0028] The bending test assembly 5 includes a pressure sensor 51, which is fixedly connected to the output end of the hydraulic device 41. The detection end of the pressure sensor 51 is fixedly connected to a pressure detection block 52 that is in active contact with the cylindrical automotive component.

[0029] Specifically, the hydraulic device 41 provides lifting pressure, which drives the pressure sensor 51 to press down the cylindrical automotive component that is limited on a pair of automotive component supports 3. By continuously applying pressure, the bending shape of the automotive component is changed, and the existing computer processing system can calculate the bending resistance data from the output of the pressure sensor 51.

[0030] The bottom end of the pressure plate 7 is rounded, which increases the sliding performance.

[0031] The automotive component support 3 has a limiting groove 31 and a moving groove 9, which are connected. The limiting groove 31 is used to place the cylindrical automotive component, and the clamping plate 10 moves through the moving groove 9. The clamping plate 10 in this application is triangular in shape, and one end of it can be treated with anti-slip treatment, such as adding an anti-slip pad, which can improve the stability of the automotive component in the limiting groove 31.

[0032] The pressure-fixing transmission mechanism 11 includes a fixed frame 111, which is fixedly connected to one side of the automotive component support 3. A rectangular slide rod 112 is slidably connected to the fixed frame 111. The rectangular slide rod 112 slides and passes through the fixed frame 111. One end of the rectangular slide rod 112 is fixedly connected to a triangular seat 113, and the other end of the rectangular slide rod 112 is fixedly connected to the pressure plate 10. The triangular seat 113 is slidably connected to the pressure plate 7. A compression spring 114 is sleeved on the rectangular slide rod 112. The compression spring 114 can give the pressure plate 10 the ability to return to its original position after being pressed. The two ends of the compression spring 114 are respectively fixedly connected to the opposite surfaces of the triangular seat 113 and the fixed frame 111.

[0033] Specifically, when the hydraulic device 41 drives the bending test assembly 5 to bend the cylindrical automotive component downwards, the hanger 6 can simultaneously lower the pressure plate 7. Once the bottom end of the pressure plate 8 contacts the triangular seat 113, the pressure plate 8 can move laterally through the triangular seat 113. Since the pressure plate 8 has a certain length, the continuously descending pressure plate 8 can be set at one end of the triangular seat 113 to limit the reverse position of the triangular seat 113. When the triangular seat 113 moves laterally, it can drive the clamping plate 11 through the moving groove 9 and clamp it onto the cylindrical automotive component in the limiting groove 31 via the rectangular slide rod 113. After the cylindrical automotive component is fixed, the bending test assembly 5 will contact the cylindrical automotive component for testing. Therefore, the fixing step can be achieved simultaneously during the bending resistance test of the automotive component, which is more convenient.

[0034] In this embodiment, since the limiting groove 31 can accommodate cylindrical automotive parts of various diameters, this application provides a spacing adjustment structure 8. The spacing adjustment structure 8 includes a precision lead screw 81, which is rotatably connected to the hanger 6 and threadedly connected to the pressure plate 7. One end of the precision lead screw 81 is fixedly connected to a rotating head 82, and a smooth rod 83 is fixedly connected to the hanger 6. The smooth rod 83 is slidably connected to the pressure plate 7.

[0035] Specifically, by rotating the precision lead screw 81, and with the guide rod 83 providing a limiting and guiding function for the pressure plate 7, the spacing between the pressure plate 7 and the hanger 6 can be adjusted. This allows for easy adjustment of the position of the end of the pressure plate 7 on the inclined surface of the triangular seat 113, thus satisfying the adjustment of the sliding path of the rectangular slide rod 112.
