The reed suspension structure of a vibration table for vibration testing of precision parts described in the utility model can further alleviate the vibration frequency of the connection mechanism, can effectively prevent the connection between the vibration motor and the vibration table from loosening, ensure the normal operation of the vibration table, and enable it to be installed and fitted more conveniently, with strong practicality and better prospects for use.

[0004] Based on the above patent, a buffer connection mechanism is set up, which is composed of a parallel plate, a buffer plate, a connecting column and a locking nut. Connecting columns are provided at the four corners of the lower end of the parallel plate to facilitate connection with the spring. Locking nuts are also provided to make the connection more secure and not easy to loosen its own parts due to frequent shaking of the vibration table. A buffer plate is also provided at the lower end of the parallel plate to further alleviate the vibration frequency of the connection mechanism, which can effectively prevent the connection between the vibration motor and the vibration table from loosening and ensure the normal operation of the vibration table. An easy-to-install mechanism is set up, and a plurality of groups of symmetrical mounting pins are respectively provided at the upper end of the connecting plate to facilitate the connection between the connecting plate and the work surface, and a rubber pad is provided at the lower end of each mounting pin.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-5 , the utility model provides an embodiment: a clock source vibration test anti-loosening structure, including a base 1, the top four sides of the base 1 are connected with a connecting ring 18 through a first spring 2, the top of the connecting ring 18 is installed with a connecting pipe 3, the outer wall of the connecting pipe 3 is connected with a fixed shell 10 through a disassembly component, the top of the connecting pipe 3 is fixedly connected with a parallel plate 4, the top four sides of the parallel plate 4 are provided with preset grooves 5, the inner walls of the preset grooves 5 are fixedly connected with rubber pads 6, the middle part of the top of the base 1 is provided with a mounting groove 7, the inner wall of the rubber pad 6 is fixedly connected with a mounting tube 8, the inner wall of the mounting tube 8 is connected with a threaded column 9 through an anti-loosening component, the top of the first spring 2 is fixedly connected to the bottom end of the connecting ring 18, and the bottom ends of the first spring 2 are respectively fixedly connected to the four sides of the top of the base 1, the rubber pad 6 can also effectively reduce friction during installation, reducing the wear force between parts, and the first spring 2 cooperates with vibration to generate vibration.

[0027] The outer wall of the threaded column 9 is threadedly connected with an assembly column 11, and the bottom end of the assembly column 11 is fixedly connected with a fixing plate 19. The outer wall of the threaded column 9 is installed with a connecting frame 12 corresponding to the bottom end of the fixing plate 19. The four sides of the outer wall of the connecting frame 12 are rotatably connected with clamping claws 13. The bottom end of the connecting frame 12 is connected to the bottom end of the inner wall of the mounting tube 8 through the second spring 14. The top of the first spring 2 is fixedly connected to the bottom end of the connecting ring 18, and the top of the second spring 14 is fixedly connected to the bottom end of the connecting frame 12. The bottom end of the second spring 14 is fixedly connected to the bottom end of the inner wall of the mounting tube 8. The opposite end of the clamping claw 13 is rotatably connected to the inner wall of the mounting tube 8. The second spring 14 lifts the connecting frame 12 so that the clamping claw 13 can be clamped. The claws 13 are opened. After the clock source is placed on the parallel plate 4, the assembly column 11 is rotated to allow the assembly column 11 to move along the outer wall of the threaded column 9. When the assembly column 11 moves, the connecting frame 12 is pressed downward to allow the connecting frame 12 to drive the clamping claws 13 to retract inward, and the clamping claws 13 are clamped on the fixed plate 19. The fixed plate 19 allows the assembly column 11 to be stably fixed on the threaded column 9, thereby improving the tightness of the connection between the threaded column 9 and the assembly column 11, avoiding long-term vibration during vibration testing of the clock source causing looseness between the threaded column 9 and the assembly column 11, and allowing the clock source to be stably tested during vibration testing to maintain the continuous progress of the experiment.

[0028] The inner wall of the fixed shell 10 is rotatably connected with a bidirectional screw rod 15, and the left and right sides of the outer wall of the bidirectional screw rod 15 are threadedly connected with a moving plate 16.

The opposite ends of the moving plates 16 at the front and rear ends are slidably connected to the inner wall of the fixed shell 10, and the opposite ends of the moving plates 16 can be detachably connected to the outer wall of the connecting ring 18. At the same time, when the first spring 2 is replaced, the bidirectional screw rod 15 at the fixed shell 10 is rotated to allow the bidirectional screw rod 15 to drive the moving plate 16 to move inward, so that the moving plate 16 passes through the fitting groove 17 at the connecting tube 3 and is stuck in the connecting ring 18 at the first spring 2, so that the first spring 2 is fixed at the connecting tube 3. When the bidirectional screw rod 15 is reversed, the moving plate 16 can fall off from the connecting ring 18, so that the first spring 2 can be replaced. By using the replaceable first spring 2, springs of different specifications can be replaced according to test requirements, thereby increasing the flexibility of the clock source to adapt to different test environments, and adding more experimental data to facilitate researchers to conduct experimental research.

[0029] Working principle: firstly, the clock source needs to be placed at the parallel plate 4, and then the assembly column 11 is rotated to move the assembly column 11 along the outer wall of the threaded column 9. When the assembly column 11 moves, the connecting frame 12 is pressed downward to make the connecting frame 12 drive the clamping claw 13 to retract inward, and the clamping claw 13 is clamped at the fixing plate 19, so that the fixing plate 19 allows the assembly column 11 to be stably fixed at the threaded column 9, thereby improving the tightness of the connection between the threaded column 9 and the assembly column 11, avoiding the looseness between the threaded column 9 and the assembly column 11 caused by long-term vibration during the vibration test of the clock source, so that the clock source can be stably tested during the vibration test, and the experiment can be continued. When replacing the first spring 2, rotate the bidirectional screw 15 at the fixed shell 10 to allow the bidirectional screw 15 to drive the movable plate 16 to move inward, so that the movable plate 16 passes through the fitting groove 17 at the connecting tube 3 and is stuck in the connecting ring 18 at the first spring 2, so that the first spring 2 is fixed at the connecting tube 3. When the bidirectional screw 15 is operated in reverse, the movable plate 16 can be dropped from the connecting ring 18, so that the first spring 2 can be replaced. By using the replaceable first spring 2, springs of different specifications can be replaced according to test requirements, thereby increasing the flexibility of the clock source to adapt to different test environments and adding more experimental data to facilitate researchers to conduct experimental research.
