[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7This utility model provides a technical solution: a mechanical vibration testing machine with a built-in shock absorption structure, including a testing platform 1, a vibrating plate 2 on the upper side of the testing platform 1, a first through groove 3 inside the vibrating plate 2, a collection box 4 fixedly connected to the lower surface of the vibrating plate 2, the collection box 4 and the first through groove 3 being connected, a second through groove 5 inside the testing platform 1, the collection box 4 being slidably connected inside the second through groove 5, two sliding grooves 6 on the inner wall of the first through groove 3, and a placement plate 7 slidably connected inside each of the two sliding grooves 6, with the inner sides of the first through groove 3... The walls are provided with guide grooves 8, which extend into the interior of the sliding grooves 6 on both sides. Guide blocks 10 are fixedly connected to both sides of the two placement plates 7. The placement plates 7 are slidably connected to the interior of the guide grooves 8 through the guide blocks 10. A bidirectional threaded rod 9 is rotatably connected inside the right guide groove 8. The two guide blocks 10 on the right are threaded onto the opposite threads at both ends of the bidirectional threaded rod 9. A connecting component is provided at the front end of the bidirectional threaded rod 9. A fixing component is provided on the upper surface of the vibration plate 2. A vibration component and a buffer component 28 are provided on the lower surface of the detection table 1.

[0026] Among them, the buffer component 28 is an existing structure, including dampers, shock-absorbing springs, vibration-absorbing pads, etc., so it will not be described in detail in this article.

[0027] In the above embodiment, the bottom wall of the collection box 4 is set as an inclined surface, and a door is rotatably connected to the right side of the collection box 4. When it is necessary to clean the broken glass inside, the door can be opened so that the glass can slide down with the help of the inclined surface.

[0028] A guide rod 11 is fixedly connected inside the left guide groove 8, and two guide blocks 10 on the left side are slidably sleeved on the outside of the guide rod 11.

[0029] The connecting assembly includes a drive rod 12, which is fixedly connected to the front end of a bidirectional threaded rod 9. The front end of the drive rod 12 rotates through the interior of the vibrating plate 2. A handle 13 is slidably sleeved on the front end of the drive rod 12. A sliding chamber 14 is opened inside the handle 13. A limiting plate 15 is fixedly connected to the front end of the drive rod 12. The limiting plate 15 is slidably connected inside the sliding chamber 14.

[0030] A first spring 16 is fixedly connected between the limiting plate 15 and the inner wall of the sliding chamber 14. The first spring 16 is movably sleeved on the outside of the drive rod 12. By allowing the drive rod 12 to slide in the sliding chamber 14 with the help of the limiting plate 15, the double-threaded rod 9 can be smoothly driven to rotate when the operator turns the handle 13, thereby driving the two placement plates 7 to move.

[0031] A locking rod 18 is fixedly connected to the rear surface of the handle 13, and a locking groove 17 is provided on the front surface of the vibration plate 2. The locking groove 17 and the locking rod 18 are compatible. The stability of the handle 13 is effectively improved by setting the locking groove 17 and the locking rod 18, thereby ensuring the stability of the bidirectional threaded rod 9.

[0032] The vibration assembly includes two mounting plates 19, both of which are fixedly connected to the lower surface of the testing table 1. A rotating shaft 20 is rotatably connected between the two mounting plates 19. Two cams 21 are fixedly sleeved on the outside of the rotating shaft 20. Two push rods 22 are slidably sleeved inside the testing table 1. The upper ends of the two push rods 22 are fixedly connected to the lower surface of the vibration plate 2. The lower ends of the push rods 22 abut against the cams 21 through a movably sleeved ball.

[0033] A return spring 23 is fixedly connected between the upper surface of the testing table 1 and the lower surface of the vibrating plate 2. The return spring 23 is movably sleeved on the outside of the push rod 22. A motor 24 is fixedly connected to the surface of the front mounting plate 19. The output shaft of the motor 24 rotates through the interior of the mounting plate 19. The output shaft of the motor 24 is fixedly connected to the front end of the rotating shaft 20 through a coupling.

[0034] Among them, the motor 24 is matched with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.

[0035] In the above embodiment, when the vibration component drives the vibration plate 2 to vibrate, the first spring 16 prevents the locking rod 18 from disengaging from the locking groove 17, thereby effectively ensuring the stability of the handle 13 and effectively preventing the bidirectional threaded rod 9 from rotating.

[0036] The fixing assembly includes two frames 25, both of which are fixedly connected to the upper surface of the vibrating plate 2. Pressure plates 26 are slidably connected between the vertical plates on both sides of the two frames 25. An adjusting screw 27 is rotatably connected to the upper surface of the pressure plate 26, and the upper end of the adjusting screw 27 is threaded through the interior of the frame 25.

[0037] The lower surface of the pressure plate 26 is also provided with a rubber pad. The rubber pad not only increases the friction between the pressure plate 26 and the glass, but also avoids hard contact between the pressure plate 26 and the glass, thus improving the safety of the glass.

[0038] Working principle:

[0039] In use, this mechanical vibration testing machine with its built-in shock absorption structure first places the optical glass to be tested on the upper side of the two placement plates 7. Then, rotating the adjusting screw 27 causes the pressure plate 26 to press the glass, thus fixing it in place. Subsequently, the motor 24 is started, and the rotation of the output shaft of the motor 24 drives the rotation of the rotating shaft 20. The rotation of the rotating shaft 20 drives the rotation of the cam 21. The rotation of the cam 21 forces the push rod 22 to move, which in turn causes the vibrating plate 2 to vibrate vertically. At this time, the return spring 23 also deforms. When the cam 21 forces the vibrating plate 2 to move upward, the return spring 23 will stretch. When the cam 21 rotates to the horizontal, the elasticity of the return spring 23 will cause the vibrating plate 2 to return to its original position, and the push rod 22 will always be pressed against the cam 21, ultimately achieving the vibration of the vibrating plate 2, thereby realizing the testing of the glass.

[0040] Meanwhile, when testing the glass, a buffer component 28 is installed on the underside of the testing table 1 to buffer the testing table 1, thereby effectively reducing the vibration of the testing table 1 itself.

[0041] If the glass breaks due to excessive vibration or defects in the glass itself, the worker can pull the handle 13 outward. At this time, the handle 13 will cause the locking rod 18 to disengage from the locking groove 17, and the first spring 16 will deform. Then the worker can rotate the handle 13. The rotation of the handle 13 will drive the rotation of the bidirectional threaded rod 9. The rotation of the bidirectional threaded rod 9 will drive the guide block 10 to slide inside the guide groove 8, thereby driving the placement plate 7 to slide inside the sliding groove 6. At this time, the upper surface of the placement plate 7 will slide against the top wall of the sliding groove 6, thereby pushing the broken glass located on the upper side of the placement plate 7 down. The broken glass will then fall into the collection box 4 through the first through groove 3, thus collecting the glass and effectively reducing the workload of the workers.

[0042] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
