Description

Technical Field

[0001] This utility model relates to a tempered glass shot bag testing machine, belonging to the field of impact testing technology. Background Technology

[0002] Tempered glass, with its high strength, impact resistance, and the absence of sharp edges in its shattered fragments, is widely used in various fields such as building doors and windows, curtain walls, and vehicle windows. The impact resistance of tempered glass is one of its core quality indicators, directly affecting safety during use. Therefore, it requires rigorous testing using specialized equipment. The shot bag impact test is one of the core methods for evaluating the impact resistance of tempered glass.

[0003] Currently available tempered glass shot bag testing machines have the following shortcomings during use: First, the glass clamping mechanism is difficult to fix, and installation and disassembly are time-consuming and laborious; second, when the glass is placed, the bottom lacks a support structure, making it inconvenient to clamp and fix the glass.

Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1, as Figures 1 to 6As shown, this utility model is a tempered glass shot bag testing machine, including a vertically arranged support frame 7, a lifting frame 22, a shot bag 14, and a lifting frame 8 for supporting the glass. The lifting frame 8 is rotatably mounted on the top of the support frame 7. The lifting frame 22 is provided with a lifting mechanism that drives the lifting frame 8 to rotate. The support frame 7 is provided with a pressing frame plate 3 on the side near the lifting frame 22. A support support plate 15 is provided below the pressing frame plate 3 and is fixed on the support frame 7. The front and rear side walls of the pressing frame plate 3 are provided with multiple opening slots. Each opening slot is provided with a locking screw 11. One end of the locking screw 11 is rotatably mounted on the support frame 7. A pressing nut 12 is provided on the locking screw 11. A hoisting steel wire rope 9 connected to the top of the support frame 7 is fixed to the top of the shot bag 14. The lifting frame 8 is provided with a clamping and releasing mechanism for clamping and releasing the shot bag 14.

[0026] Working process: Place the tempered glass to be tested on the support plate 15, so that one side of the glass is in contact with the support frame 7. Then place the clamping frame plate 3 on top, so that the clamping frame plate 3 presses down on the tempered glass. Then rotate the locking screw 11 so that the locking screw 11 rotates into the opening groove. Then tighten the clamping nut 12 until the clamping frame plate 3 presses down on the tempered glass, thus completing the fixation of the tempered glass. Next, clamp the shot bag 14 using the clamping release mechanism. Then, the lifting mechanism rotates the lifting frame 8, so that the shot bag 14 rises. When it reaches the required height, it stops. Then the clamping release mechanism releases the shot bag 14. The shot bag 14 swings downward under its own weight, impacting the tempered glass to be tested, thus completing one impact resistance test. After the test is completed, rotate the clamping nut 12 in the opposite direction to release the clamping frame plate 3 and take out the tested glass.

[0027] In Example 2, based on Example 1, rubber layers are fixed to the inner side of the clamping frame 3 and the outer side of the support frame 7. After the tempered glass is placed, the rubber layers on the clamping frame 3 and the support frame 7 clamp the tempered glass.

[0028] A support plate is provided on the upper inner side of the support frame 7, corresponding to the upper part of the clamping frame plate 3. A rubber layer is also provided on the support plate. A lifting ring is fixed to the top of the hoisting wire rope 9. The lifting ring is fixed to the crossbar at the top of the support frame 7, and the lifting frame 8 is also rotatably mounted on the crossbar via a pivot.

[0029] The support frame 7 has a support base plate 2 on both the front and rear sides. The support base plate 2 has a bottom support square tube 1 below it. The bottom support square tube 1 has an anchor bolt in its mounting hole. The upper end of the anchor bolt passes through the support base plate 2 and is connected to a lock nut.

[0030] A reinforcing rod 4 is fixed to the side of the support base plate 2 away from the lifting frame 22. The upper end of the reinforcing rod 4 is fixed to the support frame 7. A reinforcing tube 5 is fixed to the side of the bottom support square tube 1 away from the lifting frame 22. A fixing plate is fixed to the upper end of the reinforcing tube 5. The fixing plate is fixed to the support frame 7 by bolts.

[0031] The bottom of the lifting frame 22 is fixed with a bottom support square tube 2, and a reinforcing rod 2 is fixed to the outside of the bottom support square tube 2. The top of the reinforcing rod 2 is fixed to the lifting frame 22.

[0032] The clamping mechanism includes a housing 19 fixed to the end of the lifting frame 8. A clamping electric cylinder 24 is hinged inside the housing 19. A control plate 10 is hinged to the other end of the clamping electric cylinder 24. The middle part of the control plate 10 is rotatably mounted on the housing 19. A through-hole is provided at the lower left corner of the housing 19. A U-shaped connecting plate is fixed through the through-hole at the lower end of the control plate 10. A stop pin is provided at the lower end of the connecting plate. An ear plate is fixed at the bottom of the housing 19. A hanging plate 20 is hinged to the ear plate. A lifting rope 13 is provided on the side of the shot bag 14 away from the pressing frame plate 3. A connecting ring that is fitted on the hanging plate 20 is fitted on the lifting rope 13.

[0033] A stop wheel 17 is fitted on the outside of the stop pin, and the two ends of the lifting rope 13 are fixed to the top and bottom of the shotgun bag 14, respectively. When clamping the shotgun bag 14, the shotgun bag 14 is moved by lifting the lifting rope 13, so that the connecting ring is fitted onto the hanging plate 20. Then the hanging plate 20 is rotated clockwise, and then the clamping cylinder 24 extends, driving the control plate 10 to rotate around the center. The left end of the hanging plate 20 is inserted into the U-shaped groove of the connecting plate, and the bottom of the left end of the hanging plate 20 is supported on the top of the stop wheel 17. When it is necessary to release the shotgun bag 14, the clamping cylinder 24 retracts, so that the lower end of the control plate 10 moves to the left, the connecting plate disengages from the left end of the hanging plate 20, and under the action of gravity, the hanging plate 20 rotates counterclockwise. Then the connecting ring disengages from the hanging plate 20, and the shotgun bag 14 swings and hits the tempered glass.

[0034] The lifting mechanism includes a lifting wire rope connected to the lifting frame 8. A pulley is fixed to the top of the lifting frame 22. A protective box 21 is provided on the outer side below the lifting frame 22. A winding shaft is rotatably installed inside the protective box 21. The winding shaft is connected to a winding motor 18. A through hole is provided at the top of the protective box 21, and the bottom of the lifting wire rope passes through the through hole and is fixedly connected to the winding shaft. A fixing ring for connecting the lifting wire rope is provided at the upper left corner of the box body 19.

[0035] A control box 23 is mounted on the lifting frame 22. A horizontal threading tube 16 is installed between the lifting frame 22 and the support frame 7, with vertical threading tubes 6 fixed to both ends of the horizontal threading tube 16. The control box 23 is equipped with a power switch and switches for controlling the operation of the winding motor 18 and the clamping cylinder 24. When the power switch is turned on and the winding switch button of the winding motor 18 is pressed, the winding motor 18 drives the winding shaft to rotate forward, winding the lifting wire rope, thereby driving the lifting frame 8 to rotate upward and lift. When the unwinding switch button of the winding motor 18 is pressed, the winding motor 18 drives the winding shaft to rotate in reverse, unwinding the lifting wire rope, and the lifting frame 8 rotates downward under gravity. When the clamping button of the clamping cylinder 24 is pressed, the clamping cylinder 24 extends; when the release button of the clamping cylinder 24 is pressed, the clamping cylinder 24 retracts.
