[0022] In this embodiment, the first direction is the length direction of the test platform, and the second direction is the width direction of the test platform.
[0023] Please refer to Figures 2 to 4 As shown, a window glass stiffness testing device of the present utility model includes a test platform 1, a fixture 2 and an impact device 3; the fixture 2 is arranged on the tabletop of the test platform 1, the impact device 3 includes a thruster 31 and a moving mechanism 32, the thruster 31 is arranged on the movable end of the moving mechanism 32, and the moving mechanism 32 is used to drive the thrust head of the thruster 31 towards the test point of the window glass clamped by the fixture 2.
[0024] Working principle: The fixture 2 and the impact device 3 are added on the test platform 1. The window glass is clamped by the fixture 2. The moving mechanism 32 drives the thruster 31 to move according to the position of the test point 4 of the clamped window glass, so that the thrust head of the thruster 31 can face the test point 4 of the window glass. Finally, the thrust head of the thruster 31 applies force to the test point 4 of the window glass, thereby obtaining relevant test data.
[0025] Preferably, the thruster 31 is a thrust electric cylinder, and a pressure sensor is arranged on the thrust rod of the thrust electric cylinder. The pressure value of the thrust electric cylinder hitting the test point 4 of the window glass is measured by the pressure sensor. During the test, it can be that the thrust head of the thrust electric cylinder abuts against the test point 4 of the window glass and continuously increases the thrust until the test point 4 of the window glass is burst, and finally a thrust value and a thrust head displacement curve graph are generated, recording the maximum force value borne at the time of fragmentation, and outputting test data. It can also be that the thrust electric cylinder reciprocally hits the test point 4 of the window glass with the same force until the test point 4 of the window glass is broken; it can also be that the thrust electric cylinder reciprocally hits the test point 4 of the window glass with a gradually increasing force until the test point 4 of the window glass is broken, and finally a thrust value and a thrust head displacement curve graph are generated, recording the maximum force value borne at the time of fragmentation, and outputting test data.
[0026] Please refer to Figure 3As shown in the figure, further, the moving mechanism 32 includes a first linear reciprocating device 321 and a second linear reciprocating device 322; the first linear reciprocating device 321 is arranged on the tabletop of the test platform 1, the first linear reciprocating device 321 has a moving end that moves in the first direction along the tabletop of the test platform 1, the second linear reciprocating device 322 is arranged on the moving end of the first linear reciprocating device 321, the second linear reciprocating device 322 has a moving end that moves in a direction perpendicular to the tabletop of the test platform 1, and the thruster 31 is arranged on the moving end of the second linear reciprocating device 322.
[0027] As can be seen from the above description, the moving mechanism 32 can drive the thruster 31 to move above the tabletop of the test platform 1 through the first linear reciprocating device 321 and the second linear reciprocating device 322, so that the thrust head of the thruster 31 faces the test point 4 of the window glass.
[0028] Please refer to Figure 4 As shown in the figure, further, the fixture 2 includes a third linear reciprocating device 21, a first jaw 22 and a second jaw 23; the third linear reciprocating device 21 is arranged on the tabletop of the test platform 1, the third linear reciprocating device 21 has a moving end that moves in the first direction along the tabletop of the test platform 1, the first jaw 22 is arranged on the moving end of the third linear reciprocating device 21, and the second jaw 23 is arranged on the tabletop of the test platform 1.
[0029] As can be seen from the above description, according to the window glass of different lengths, the third linear reciprocating device 21 can be used to drive and control the distance between the first jaw 22 and the second jaw 23, so that the fixture 2 can effectively clamp window glasses of different sizes and lengths.
[0030] Among them, the clamping ends of the first jaw 22 and the second jaw 23 are detachable profiling blocks, so that the window glass with different curvatures can be effectively clamped as a whole.
[0031] Please refer to Figure 4 As shown in the figure, further, the fixture 2 further includes a fourth linear reciprocating device 24, the fourth linear reciprocating device 24 is arranged on the tabletop of the test platform 1, the fourth linear reciprocating device 24 has a moving end that moves in the second direction along the tabletop of the test platform 1, the second direction is perpendicular to the first direction, and the second jaw 23 is arranged on the moving end of the fourth linear reciprocating device 24.
[0032] As can be seen from the above description, if there is a dislocation in the clamping position of the window glass to be tested, the position of the second jaw 23 can be adjusted through the fourth linear reciprocating device 24, so that the fixture 2 can effectively clamp window glasses of more shapes.
[0033] Please refer to Figure 2As shown, further, a protective cover 11 is provided on the test platform 1. The protective cover 11 and the tabletop of the test platform 1 enclose a test space, and the fixture 2 and the impact device 3 are located in the test space.
[0034] As can be seen from the above description, the protective cover 11 can prevent the glass debris generated during the window glass test from flying everywhere.
[0035] Please refer to Figure 2 As shown, further, a slag discharge hole 12 is provided on the test platform 1, and a debris collector 13 for receiving the slag discharge hole 12 is provided below the test platform 1. Preferably, the debris collector 13 includes a material receiving hopper 131 and a collection box 132; the feeding end of the material receiving hopper 131 receives the slag discharge hole 12, and the discharging end of the material receiving hopper 131 is in butt connection with the box opening of the collection box 132.
[0036] As can be seen from the above description, after the stiffness test of the window glass is completed, the glass debris on the tabletop of the test platform 1 can flow into the collection box 132 through the slag discharge hole 12 from the material receiving hopper 131 and be collected uniformly.
[0037] Further, the window glass stiffness test device further has an industrial control computer communicatively connected to the fixture 2 and the impact device 3. When testing a window glass not recorded in the memory of the industrial control computer, the operator can manually adjust the positions of the first jaw 22 and the second jaw 23 on the industrial control computer according to the digital model drawing of the window glass, record the positions of the first jaw 22 and the second jaw 23 in the memory of the industrial control computer, and replace the corresponding profiling blocks on the clamping ends of the first jaw 22 and the second jaw 23. Then manually adjust the first linear reciprocating device 321 and the second linear reciprocating device 322 on the industrial control computer so that the thrust head of the thruster 31 faces the test point 4 of the window glass, and record the position of the thruster 31 in the memory of the industrial control computer. Then the operator can clamp the window glass on the first jaw 22 and the second jaw 23, and finally close the protective cover 11 to start the test.
[0038] When testing a window glass already recorded in the memory of the industrial control computer, the operator can operate the industrial control computer to ventilate, so that the first jaw 22, the second jaw 23 and the thruster 31 are automatically in place, then replace the corresponding profiling blocks on the clamping ends of the first jaw 22 and the second jaw 23, clamp the window glass, and finally close the protective cover 11 to start the test.
