Description

Technical Field

[0001] This utility model relates to the field of tempered glass testing technology, and in particular to a device for testing the impact resistance of physically tempered glass against a falling ball. Background Technology

[0002] Glass is an amorphous, grade 5 non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, and soda ash) as the main raw materials, with the addition of small amounts of auxiliary materials. Its main component is silicon dioxide and other oxides. It is widely used in buildings for wind insulation and light transmission, and is a mixture. To improve the strength of glass, chemical or physical methods are usually used to create compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving its load-bearing capacity. After glass production, tempered glass samples need to be randomly inspected, and impact tests are performed on the samples to observe the damage.

[0003] However, current ball drop impact testing devices use a fixed ball drop position when testing tempered glass. To measure different positions of the tempered glass, the position of the tempered glass needs to be manually adjusted, which is inefficient and labor-intensive.

[0004] Therefore, a device for testing the impact resistance of physically strengthened glass by falling a ball is proposed. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] 1. In this utility model, the first lead screw is driven by the third motor to rotate, which pushes the slider to push the placement frame so that the tempered glass can move back and forth. The third lead screw is driven by the second motor to rotate, which moves the slider left and right, so that the falling ball attracted by the electromagnet at the lower end also moves left and right. This allows the falling ball impact test to be performed at different positions of the tempered glass during the falling ball test, which can reduce the need for manual adjustment of different test positions, making the working speed faster and the test simpler.

[0020] 2. In this utility model, the first motor drives the second lead screw, which allows the moving slide rail to adjust the height of the falling ball up and down. This allows the ball to be dropped onto tempered glass at different heights, enabling the drop force to be tested. This avoids the need for manual adjustment of the ball height, resulting in better testing results and higher safety.

[0021] 3. In this utility model, a force plate is installed at the bottom of the placement frame via a pressure sensor. When the tempered glass placed on the force plate is subjected to an impact, it can apply a downward force to the pressure sensor, thereby detecting the magnitude of the impact and improving the testing results.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] Please see Figures 1-3This utility model provides a device for testing the impact resistance of physically tempered glass by falling ball. It includes a base 1 to increase the stability of the bottom, and a controller 2 installed on the outside of the base 1, so that the operator can operate the electrical components in the device through the controller 2, which makes the operation effect better. A force plate 12 is attached to the inside of the placement frame 4. A pressure sensor 11 is installed at the bottom of the force plate 12 and connected to the placement frame 4. When the tempered glass is placed on the force plate 12 for impact force testing, the falling ball 119 falls downward and the impact force generated on the tempered glass puts pressure on the force plate 12, which in turn applies the pressure sensor 11 to test the impact force, so as to facilitate the operator to detect the impact force. The outside of the placement frame 4 is provided with an openable side door 13, so that after the impact test, the broken tempered glass can be swept out through the side door 13, which makes the working effect better.

[0030] The upper part of the base 1 has a movable cavity 3 to facilitate the installation of other components inside, enabling the pushing of the upper placement frame 4. The movable cavity 3 is connected to the upper-opening placement frame 4 through a moving mechanism, which facilitates the placement of tempered glass inside the placement frame 4 for testing. The side height of the placement frame 4 is increased to reduce the outward scattering of fragments when broken, thus improving safety. The moving mechanism includes a first lead screw 9 mounted inside the movable cavity 3 via bearings, and positioning slide rods 10 on both sides. A third motor 122 is installed on the outside of the base 1 and connected to the first lead screw 9. The bottom of the placement frame 4 has a... Push slider 5, which has a first threaded hole 6 inside and is connected to the first lead screw 9, is pushed by the third motor 122 to rotate the first lead screw 9, causing the push slider 5 to push the placement frame 4 to move back and forth, thereby adjusting the longitudinal position of the tempered glass and conducting impact tests at different positions. Limiting sliders 7 are provided on both sides of the bottom end of the placement frame 4. Limiting sliding holes 8 are provided inside the limiting sliding holes 8 and are slidably connected to the positioning sliding rod 10, thereby increasing the stability of the placement frame 4 and increasing the support force, reducing the impact on the first lead screw 9 when falling, and making the use effect better.

[0031] A reinforcing column 16 is mounted upwards on one side of the base 1 to fix the top plate 17 at the upper end, making the force more stable. A scale 19 is provided on the outside of the reinforcing column 16 to facilitate the operation when adjusting the height of the movable slide rail 110. The top of the reinforcing column 16 is connected to the top plate 17 to bear the force at the upper end. A mounting cavity 14 is provided on one side of the base 1, and a first motor 15 is installed inside the mounting cavity 14. A second lead screw 18 is connected between the top plate 17 and the base 1 through a bearing, and the output end of the first motor 15 is connected to the second lead screw 18. A movable slide rail 110 is mounted on the upper end of the base 1. A second threaded hole 111 is provided on one side of the movable slide rail 110 to connect with the movable slide rail. Hole 112 is connected to the second lead screw 18 and the reinforcing column 16 respectively. The first motor 15 drives the second lead screw 18, which can be moved up and down under the action of the second threaded hole 111 to adjust the height of the falling ball 119, which is convenient for adjustment and testing. The sliding connection between the sliding hole 112 and the reinforcing column 16 increases the stability of the side, making the movement effect better and facilitating accurate height adjustment. A telescopic rod 121 is installed on the outside of the top plate 17 and connected to the sliding rail 110. The telescopic rod 121 enhances the stability of the side of the sliding rail 110, preventing the other side from tilting due to force on one side, thus improving the working effect.

[0032] Please see Figure 1 , Figure 3 and Figure 4 The sliding rail 110 has a downward-through push groove 113 inside, which facilitates the movement of the internal sliding block 116, which drives the electromagnet 118 to move left and right. A third lead screw 114 is connected to the inside of the push groove 113 via a bearing. A second motor 115 is mounted on the outside of the sliding rail 110 and connected to the third lead screw 114. The sliding block 116 is installed inside the push groove 113, and the sliding block 116 has a third threaded hole 117 connected to the third lead screw 114. When the second motor 115 drives the third lead screw 114 to rotate, the internal sliding block 116 can be moved. The slider 16 moves the ball 119 left and right to adjust the impact position, allowing for impact testing at different locations with the adjustment of the front and rear tempered glass, reducing manual adjustment time. An electromagnet 118 is installed at the bottom of the slider 116, and the ball 119 is connected to the lower end of the electromagnet 118. The electromagnet 118 allows for external control by the operator, reducing manual operation and improving the operation effect and work efficiency. A laser pointer 120 is installed on the outside of the electromagnet 118, allowing for precise positioning of the ball under the action of the laser pointer 120, resulting in better testing results.

[0033] Working principle: In use, first connect the pressure sensor 11, the first motor 15, the second motor 115, the electromagnet 118, the laser pointer 120, and the third motor 122 to the controller 2. The controller 2 can also be connected to an external remote control for easier operation. Connect it to an external power source. Then, the electromagnet 118 attracts the ball 119, and the tempered glass is placed inside the placement frame 4. When testing is required, the third motor 122 drives the first lead screw 9, which, under the action of the first threaded hole 6, pushes the slider. 5 allows the position of the placement frame 4 to be adjusted. Under the rotation of the third lead screw 114 driven by the second motor 115, the lower sliding block 116 is forced to move the electromagnet 118 and the falling ball 119 left and right to adjust their position. Under the action of the laser pointer 120, the impact position is accurately found. Under the action of the first motor 15 through the second lead screw 18 and the second threaded hole 111, the sliding rail 110 is forced to move up and down. After adjusting the height, the falling ball 119 is loosened and dropped by the electromagnet 118 to impact, thus completing the work.
