[0002] In order to ensure the strength of the parts, vibration tests need to be performed on the parts before they are assembled. Before doing the vibration test, a vibration test fixture is needed to fix the parts to be tested on the vibration test bench. Therefore, a vibration test fixture is needed for auxiliary processing, such as:

[0003] Publication number CN106768754B discloses a vibration test fixture. When the vibration test fixture is in use, parts to be tested of various shapes and sizes can be fixed in three mutually orthogonal directions of X, Y, and Z by using the vibration test fixture. There is no need to redesign the vibration test fixture according to the shape of the parts to be tested, which improves versatility, reduces personnel workload, and facilitates vibration testing. However, the device still has certain shortcomings when in use. First, after the sample is subjected to a limited vibration test, it is necessary to disassemble the fixture and the platform, and then the transmission mechanism of the fixture is maintained and repaired through disassembly, and the above-mentioned device lacks a mechanism for disassembling the fixture.

The bottom end position of the fixed block 7 is fixed to the interior of the upper fixture 1, and the interior of the fixed block 7 is hollow. A set of sliding sleeves 11 is fixed at the outer position of the connecting rack 10, and the inner side of the sliding sleeve 11 is slidably arranged on the outer side of the guide rod 12, and one side of the guide rod 12 is fixed to the inside of the lower mounting member 2 by bolts. A rod is fixed at one side of the connecting rack 10, and the outer side of the rod extends into the inner side of the output end of the vibration test and is locked by bolts. When the lower mounting member 2 is disassembled and separated from the output end of the vibration test, the bolts at the output end of the vibration test are first rotated. At this time, the rotating bevel gear 3 is rotated to drive the meshing matching bevel gear 4, and the matching bevel gear 4 will drive the key-connected connecting rod 8 to rotate inside the fixed block 7, causing the connecting rod 8 to drive the rotating gear 9 to rotate, so that the two sets of connecting racks 10 meshed and connected on the outer side of the rotating gear 9 will move on the outer side of the guide rod 12 through the sliding sleeve 11, so that the rods driven by the two sets of connecting racks 10 are recycled, and the lower mounting member 2 and the output end of the vibration test can be separated at this time.

[0033] Example 2: In order to effectively limit the position of test samples of different sizes, please refer to the attached Figure 1 and attached Figure 3 -Attached Figure 5 The interior of the clamp block 6 includes a limiting column 601 fixed to the bottom of the clamp block 6, and grooves 602 are provided on both sides of the clamp block 6. A first placement platform 603 is provided on the left side of the top of the clamp block 6, and a second placement platform 604 is provided on the right side of the top of the clamp block 6. A protrusion 101 is fixed to the inner side of the upper end of the upper clamp 1, and the protrusion 101 is fixed in the guide groove 102 provided on the top of the upper clamp 1. Since the first placement platform 603 and the second placement platform 604 are provided on the top of the clamp block 6, the first placement platform 603 and the second placement platform 604 can be used to limit the test samples of different sizes.

The clamp 6 forms a sliding structure with the inside of the upper fixture 1 through the matching grooves 5. The movement of the three groups of clamps 6 is relatively arranged. When the rotating bevel gear 3 rotates on the outside of the upper fixture 1, one end of the rotating bevel gear 3 rotates inside the upper fixture 1, causing the matching bevel gear 4 meshed and connected on the outside of the rotating bevel gear 3 to drive the matching groove 5 to rotate. When the matching groove 5 rotates, the limiting column 601 fitted inside the matching groove 5 can drive the clamp 6 to slide inside the protrusion 101 through the groove 602. At this time, the clamp 6 slides inside the guide groove 102, which will cause the three groups of clamps 6 to move relatively. At this time, the test sample can be effectively limited.
