Description

Technical Field

[0001] This utility model relates to the field of automotive glass production technology, and in particular to a strength testing device for automotive glass production. Background Technology

[0002] The strength of automotive glass is crucial to driving safety and must meet stringent standards. Therefore, specialized equipment is required for testing during production. The strength test results of automotive glass may differ depending on whether it is placed vertically or horizontally. Thus, in automotive glass testing, the corresponding placement method is usually specified based on the glass's installation location (such as side windows or sunroofs) and the actual stress scenario (e.g., vertical testing for side windows and horizontal testing for sunroofs) to ensure that the test results accurately reflect its safety performance in the vehicle. However, existing testing equipment can only perform single-state (horizontal or vertical) testing. If the test placement method does not match the actual installation state, it may not accurately reflect the strength performance of the glass in actual use. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a strength testing device for automotive glass production. It solves the problem that existing testing devices cannot switch between horizontal and vertical states of glass on the same equipment, and require multiple loading, unloading or replacement of equipment, resulting in low efficiency and large errors; it solves the problem that the limiting structure of the adjustable state device is not stable enough, and is prone to shaking during impact testing, affecting accuracy; it also solves the problem that the traditional rigid clamping method is prone to causing glass edge damage, interfering with the test results.

[0013] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0014] Reference Figure 1-5 This utility model discloses a strength testing device for automotive glass production, comprising: a base 1, a support column 2 fixedly connected to the lower surface of the base 1, a base plate 3 fixedly connected to the upper surface of the base 1, a left support plate 4 fixedly connected to the upper surface of the base plate 3, a right support plate 5 fixedly connected to the upper surface of the base plate 3, a brake motor 6 fixedly connected to the left surface of the left support plate 4, a rotating shaft 17 fixedly connected to the output end of the brake motor 6, the rotating shaft 17 passing through the left support plate 4, a limit frame 7 fixedly connected to the end of the rotating shaft 17 away from the brake motor 6, a sliding groove 12 provided on the inner side wall of the limit frame 7, a rubber strip 13 provided on the inner side wall of the sliding groove 12, and a support shaft 18 fixedly connected to the right surface of the limit frame 7, the support shaft 18 passing through the right support plate 5; Specifically, base 1 is the basic load-bearing component of the device, used to fix and support all components of the entire testing device (such as base plate 3, electric telescopic rod, etc.), ensuring the overall stability of the device during testing. Support column 2 enhances the stability of the device when placed. Base plate 3 connects to base 1 and supports left support plate 4 and right support plate 5. Left support plate 4 and right support plate 5 are symmetrically distributed on base plate 3, together forming the support frame of limit frame 7. Left support plate 4 is used to fix brake motor 6 and provide a through channel for rotating shaft 17. Right support plate 5 provides through support for support shaft 18. The two work together to ensure the stability and coaxiality of limit frame 7 during rotation. Slide groove 12 is opened on the inner side wall of limit frame 7 to provide installation guidance for glass. Rubber strip 13 is embedded in the inner side wall of slide groove 12. Using the elasticity and friction of rubber, it avoids edge damage caused by direct contact between glass and metal slide groove, while enhancing the fixing effect of glass and preventing glass from loosening during impact. The rotation of brake motor 6 then places the inner glass plate of limit frame 7 vertically or horizontally.

[0015] Reference Figure 1-5A support plate 8 is fixedly connected to the upper surface of the limit frame 7. A top plate 9 is fixedly connected to the upper surface of the support plate 8. A hydraulic cylinder 10 is fixedly connected to the lower surface of the top plate 9. An impact rod 11 is fixedly connected to the output end of the hydraulic cylinder 10. An impact head 16 is fixedly connected to the lower end of the impact rod 11. An electric telescopic rod 14 is fixedly connected to the lower bottom wall of the base 1. An electric telescopic rod 2 15 is fixedly connected to the lower bottom wall of the base 1. Both the electric telescopic rod 14 and the electric telescopic rod 2 15 penetrate the base plate 3 and are located between the left support plate 4 and the right support plate 5. Specifically, the support plate 8 is a transition component connecting the limiting frame 7 and the top plate 9, ensuring the stability of the top plate 9 and the impact mechanism (hydraulic cylinder 10, impact rod 11, etc.) above it. Since the support plate 8 is connected to the upper surface of the limiting frame 7, the support plate 8 and the impact mechanism (hydraulic cylinder 10, impact rod 11, etc.) set on the top plate 9 are perpendicular to the glass plate limited inside the limiting frame 7, thereby allowing the glass plate to undergo strength tests in different states in the vertical and horizontal directions. When the glass plate is in the vertical state, the electric telescopic rod 14 extends, restricting the limiting frame 7 in the middle of the electric telescopic rod 14. Figure 2 To prevent it from shaking, when the glass plate is in a horizontal position, the electric telescopic rod 15 extends and supports the limiting frame 7. Figure 1 To ensure the stability of the limit frame 7, during the test, the hydraulic cylinder 10 serves as the power source for the impact test. It drives the output end to extend and retract through hydraulic pressure, causing the impact rod 11 to move rapidly, providing impact kinetic energy to the impact head 16 and allowing it to directly contact the glass (by adjusting the hydraulic pressure to control the impact force, the strength of the automotive glass can be determined).

[0016] Working principle: When the device is working, the glass is first inserted into the groove 12 of the limiting frame 7, the rubber strip 13 fixes the glass, the brake motor 6 drives the rotating shaft 17, which drives the limiting frame 7 and the support shaft 18 to rotate, and adjusts the glass to a vertical or horizontal state. When vertical, the electric telescopic rod 14 extends out to fix the limiting frame 7; when horizontal, the electric telescopic rod 2 15 extends out to support. Then, the hydraulic cylinder 10 on the top plate 9 drives the impact rod 11, so that the impact head 16 impacts the glass. The base 1, the column 2, the bottom plate 3, the left support plate 4, the right support plate 5, and the bracket plate 8 ensure overall stability and realize strength testing under different conditions.

[0017] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
