Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-4 The utility model provides a technical solution: a tempered glass hardness testing device, comprising a pedestal 1, a support frame 2 and a hardness tester 3, wherein the support frame 2 is fixedly mounted on the outer back of the pedestal 1, the hardness tester 3 is mounted on the support frame 2, the hardness tester 3 comprises a display screen 31, an electric telescopic rod 32, a probe 33 and a pressure sensor, wherein the display screen 31 is located at the top end of the support frame 2, the electric telescopic rod 32 is mounted at the front end of the support frame 2, the bottom end of the electric telescopic rod 32 is connected to the probe 33, the probe 33 has a built-in pressure sensor, and the probe 33 and the display screen 31 are electrically connected via a connecting line;
[0025] A hollow groove 4 is provided in the center of the surface of the pedestal 1. A first slide rail 5 is fixed at the center of the top of the hollow groove 4. A first screw rod 6 is provided at the bottom of the first slide rail 5. A baffle 8 is slidably mounted on the first screw rod 6 through a screw nut slider 7. The distal end of the first screw rod 6 is connected to a screw drive motor A9. A plurality of parallel mesh plates 10 are provided on both sides of the first slide rail 5.
[0026] A second slide rail 11 is provided on one side of the hollow groove 4. A bidirectional screw rod 12 is built into the interior of the second slide rail 11. A fixed base 13 is installed on the bidirectional screw rod 12 through a screw rod nut slider 7. There are two screw rod nut sliders 7 on the bidirectional screw rod 12, and the inner wall threads of the through holes of the two screw rod nut sliders 7 are arranged oppositely. The threads on the surfaces of the two end portions of the shaft of the bidirectional screw rod 12 are arranged oppositely.
[0027] A pressure plate 15 is installed on the fixed base 13 by rotating the screw 14. A folded edge 16 is provided on the side of the fixed base 13. The end of the bidirectional screw 12 is connected to the screw drive motor B17, and the screw drive motor B17 is located on the front outer surface of the base 1.
[0028] The screw drive motor A9 and the screw drive motor B17 in the present invention are both forward and reverse motors, which are used to drive the screw to rotate forward and reverse.
[0029] The screw drive motor A9 drives the first screw 6 to rotate, so that the baffle 8 moves laterally along the first slide rail 5 through the screw nut slider 7; the motor shaft of the screw drive motor A9 is fixedly connected to the first screw 6. When the first screw 6 rotates, the screw nut slider 7 at the bottom of the baffle 8 changes the rotational force into linear motion under the action of the screw nut, so that the distance between the baffle 8 and the second slide rail 11 on the left is adjusted, which is convenient for limiting and clamping the side of the tempered glass placed on the surface of the base 1.
[0030] The screw drive motor B17 drives the bidirectional screw 12 to rotate, causing the screw nut sliders 7 at the head and tail ends of the bidirectional screw 12 to move relative to each other;
[0031] When the screw drive motor B17 drives the bidirectional screw 12 to rotate clockwise, the screw nut sliders 7 at the head and tail ends of the bidirectional screw 12 move toward each other under the action of the opposing threads, so that the two fixed bases 13 move toward each other along the second slide rail 11;
[0032] When the screw drive motor B17 drives the bidirectional screw 12 to rotate counterclockwise, the screw nut sliders 7 at the head and tail ends of the bidirectional screw 12 move in opposite directions, so that the distance between the two fixed bases 13 is increased, which is convenient for adapting to different sizes of tempered glass for limited clamping.
[0033] A debris collection box 18 is plugged into the front of the base 1 and is located in the hollow groove 4 ; it is used to collect glass debris remaining during the process of testing the hardness of the tempered glass.
[0034] Working principle:
[0035] In the present invention, the tempered glass is placed at the hollow groove 4 of the pedestal 1, and the tempered glass is supported by a plurality of mesh plates 10 at the hollow groove 4. The tempered glass is manually pushed toward the second slide rail 11, so that the corner of one side of the tempered glass is abutted against the folded edge 16 of one of the fixed bases 13 at the second slide rail 11;
[0036] Then, the screw drive motor B17 starts to work, driving the bidirectional screw 12 to rotate clockwise. Under the action of the opposing threads, the screw nut sliders 7 at the head and tail ends of the bidirectional screw 12 move toward each other, causing the two fixed bases 13 to move toward each other along the second slide rail 11. At this time, one side of the two tempered glass plates is clamped by the two fixed bases 13.
[0037] Then, the screw drive motor A9 is driven to rotate the first screw 6 clockwise, so that the baffle 8 moves linearly along the first slide rail 5 toward the second slide rail 11 on the left side under the action of the bottom screw nut slider 7, so that the baffle 8 clamps against the other side of the tempered glass;
[0038] Thus, the left and right sides of the tempered glass are clamped and fixed by the limit position, and then the rotating screws 14 on the two fixed bases 13 at the bidirectional screw rod 12 are manually rotated to allow the pressing plate 15 at the bottom of the rotating screw 14 to press the left side of the tempered glass downward. At this point, the clamping and fixing of the tempered glass is completed.
[0039] The hardness tester 3 performs a hardness test on the tempered glass fixed on the base 1. The electric telescopic rod 32 drives the probe 33 to move downward to apply pressure to the tempered glass, and measures the indentation depth on the surface of the tempered glass. The pressure sensor inside the probe 33 detects the corresponding pressure value. After maintaining the pressure for a specified time, the main test force is removed, the initial test force is maintained, and the hardness value is calculated using the residual indentation depth increment.
[0040] After the inspection is completed, the screw 14 is manually rotated in the opposite direction to lift the pressure plate 15 upward on the side of the fixed base 13. The screw drive motor A9 and the screw drive unit B17 are used again to move the baffle 8 toward the right outer side of the tempered glass, and the two fixed bases 13 at the second slide rail 11 move toward the head and tail ends respectively, expanding the distance between the two fixed bases 13, and removing the tempered glass placed on the base 1. The remaining glass fragments can fall from the mesh plate 10 and the gap between the two adjacent mesh plates 10, and fall from the hollow groove 4 inside the base 1 into the debris collection box 18. The debris collection box 18 can be manually pulled out to pour out the remaining glass fragments.
[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
