Abstract
Description
Technical Field
[0001] This utility model relates to the field of strength testing technology, specifically a strength testing device for automotive glass production. Background Technology
[0002] Strength testing is required during the production of automotive glass, necessitating the use of strength testing equipment. The main methods for glass strength testing include: impact strength testing with a steel ball, drop ball breakage testing; and static pressure testing, which involves progressively increasing pressure at the center of the glass using a pin until the pressure value at the moment of glass breakage is reached.
[0003] When using the static pressure test method, the glass testing device has a fixed testing position and a limited number of pressure points, which restricts the testing capabilities. Related technologies use a glass fixing frame connected to the top of a support base. The top of the glass fixing frame has a glass placement groove. A spring in a telescopic groove on one side of the glass placement groove pushes a telescopic fixing block to move and fix the glass. Pressing the telescopic fixing block allows for fixing glass of different sizes, improving the applicability of the strength testing device. Connecting plates are fixed to both ends of a lifting plate, with a sliding groove at the center of the connecting plate. The strength testing block slides in the groove via a screw and is fixed by a knob at the top of the screw, facilitating position adjustment. However, in actual use, the strength testing block can only be adjusted in one direction, resulting in a limited adjustment function. Utility Model Content

[0029] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.

[0030] When testing the strength of automotive glass using the static pressure test method, a pressure is gradually increased at the center of the glass using a pin until the glass breaks. The magnitude of the pressure at the moment of breakage corresponds to the strength grade of the automotive glass.
[0031] In related technologies, a glass fixing frame is connected to the top of the support base. The top of the glass fixing frame has a glass placement groove. A spring in a telescopic groove on one side of the glass placement groove pushes a telescopic fixing block to move and fix the glass. Pressing the telescopic fixing block can fix glass of different sizes, which is convenient for fixing glass of different sizes and improves the applicability of the strength testing device. Connecting plates are fixed to both ends of the lifting plate. A sliding groove is opened at the center of the connecting plate. The strength test block slides in the sliding groove by a screw and is fixed by a knob at the top of the screw, which is convenient for adjusting the position of the strength test block. However, in actual use, the strength test block can only be adjusted in one direction, resulting in a relatively simple adjustment function and certain limitations.
[0032] To address some of the problems in the related technologies, this application provides a strength testing device for automotive glass production. When needed, the device simply clamps the automotive glass with the clamping block 11, then activates the electric push rod 13 to bring the pressure block 21 into contact with the automotive glass, thereby performing strength testing on the automotive glass. This method is more convenient and faster, improving the device's usability.
[0033] This application is described below with reference to the accompanying drawings and specific embodiments:
[0034] Combination Figures 1-3 This application provides a strength testing device for automotive glass production, comprising: a base 10, with a clamping block 11 on its top for clamping glass; a support frame 12 fixedly connected to the top of the base 10; an electric push rod 13 fixedly connected to the top of the support frame 12; a testing mechanism 14 at the output end of the electric push rod 13; a plate 20 slidably connected to the testing mechanism 14; a pressure block 21 slidably connected to the bottom of the plate 20; and a round head slidably connected to the side of the pressure block 21. Rod 22, with a spring 23 sleeved on its outer side. The two ends of the spring 23 are fixedly connected to the pressure block 21 and the rod 22, respectively. A connecting plate 24 is fixedly connected to the bottom of the rod 22. A plate 4 25 is slidably connected to the plate 3 20. A rod 3 26 is provided on the plate 4 25. Holes 27 are provided on both the testing mechanism 14 and the plate 3 20. The rod 3 26 and the rod 22 are respectively inserted into one of the holes 27.
[0035] After installing the base 10 in the designated position, place the car glass between the two clamps 11. Then, fix the car glass by changing the position of the clamps 11. Turn on the electric push rod 13 so that its output end pushes the testing mechanism 14. The testing mechanism 14 pushes the plate 20 and the pressure block 21 into contact with the car glass. The strength of the car glass is then tested by the testing mechanism 14. When it is necessary to change the position of the pressure block 21, pull the round-head rod 22 outward. The round-head rod 22 drives the connecting plate 24 to slide off the pressure block 21 and pulls the spring 23. Then, while one end of the round-head rod 22 slides out of the hole 27, the connecting plate 24 pulls the plate 25 and the round-head rod 26 to slide out of the other hole 27. At this time, push the pressure block 21 directly. While the pressure block 21 slides back and forth on the plate 20, the plate 20 slides left and right on the testing mechanism 14 (direction reference). Figure 1 This allows for simultaneous adjustment of the front-back and left-right positions of the pressure block 21. Finally, the round-head rod 22 is released, and the spring force of the spring 23 causes the round-head rod 22 and the round-head rod 3 26 to be inserted into the corresponding holes 27, thus fixing the position of the pressure block 21. The above steps are repeated to perform strength testing on the automotive glass.
[0036] In some embodiments, the testing mechanism 14 includes: a plate 141 fixedly connected to the output end of the electric push rod 13; a round-headed rod 142 slidably connected to the plate 141; a plate 2 143 fixedly connected to the bottom end of the round-headed rod 142; a plate 3 20 slidably connected inside the plate 2 143; and a pressure sensor 144 disposed on the top of the plate 2 143.
[0037] After the pressure block 21 contacts the car glass, the plate 143 slides upward on the support frame 12, and drives the round-headed rod 142 to slide upward on the plate 141 until the pressure sensor 144 contacts the plate 141. At this time, the electric push rod 13 continues to be driven, so that the downward pressure is applied to the car glass through the pressure block 21. At this time, the pressure sensor 144 is subjected to force and transmits the monitoring value to the processor through the cable (which is existing technology, so it will not be described in detail in the text, and the processor is not shown in the figure). The processor converts the electrical signal into a digital signal until the car glass breaks, at which point the pressure value reaches its maximum, thus completing the strength test of the car glass.
[0038] In some embodiments, the pressure sensor 144 is disposed at the center of the plate body 143, so that the pressure sensor 144 is subjected to uniform force.
[0039] In some embodiments, the plate 25 has a hole 30, the round-headed rod 26 is slidably connected to the hole 30, and a spring 31 is sleeved on the outside of the round-headed rod 26. The two ends of the spring 31 are fixedly connected to the plate 25 and the round-headed rod 26, respectively.
[0040] When adjusting the position of the pressure block 21, manually pull down the round-head rod 26 so that it slides down within the hole 30 and pulls the spring 31. Then push the plate 20 so that it drives the pressure block 21 to slide left and right, thus allowing the pressure block 21 to be adjusted left and right independently, improving its practicality.
[0041] In some embodiments, a set bolt 111 is threaded onto the clamping block 11 to raise the position of the clamping block 11.
[0042] In some embodiments, multiple round-headed rods 142 are provided to make the sliding of plate 143 more stable.
[0043] In some embodiments, the plate 20, the pressure block 21, the round-head rod 22, and the spring 23 are a group, and multiple groups are provided on the plate 243, so that multiple pressure blocks 21 can detect multiple points on the car glass.
[0044] In some embodiments, the pressure block 21 and the third plate 20 are slidably connected to the third plate 20 and the second plate 143 respectively via dovetail blocks to prevent the pressure block 21 from separating from the third plate 20 and to prevent the third plate 20 from separating from the second plate 143.
