AI Technical Summary
Existing multi-directional vibration test fixtures are large and heavy, making them difficult to use on machines with poor load performance, and their vibration test accuracy is insufficient.
Design a vibration test fixture with a three-sided structure, including a base plate, a first side plate, a second side plate, and a fixed base to form a storage space. The fixed base is used to fix the object to be tested. The base plate and the side plates are provided with mounting holes. The main body of the bracket is fixed by a support block and threaded holes. The main body of the bracket is connected to the vibration test machine to realize triaxial vibration testing.
It reduces the weight and assembly/disassembly difficulty of vibration testing fixtures, improves testing accuracy and efficiency, is suitable for machines with poor load performance, and saves procurement costs.

Abstract
Claims
1. A vibration test fixture, characterized by, It includes a fixedly connected base plate, a first side plate, a second side plate, and a fixing seat; The base plate, the first side plate, and the second side plate together form a three-sided structure with an open storage space. The fixing seat is disposed in the storage space and fixed to the base plate, the first side plate, or the second side plate. The fixing seat is used to fix the object to be tested. The base plate, the first side plate, and the second side plate are all provided with multiple mounting holes for fixing to the vibration testing machine.
2. The vibration testing fixture as described in claim 1, characterized in that, The fixed base includes a first support block, a second support block, a third support block, and a fixed bracket. The first support block, the second support block, and the third support block are all fixedly connected to the base plate. The fixed bracket is used to fix the object to be tested and is connected to the first support block, the second support block, and the third support block respectively.
3. The vibrational test fixture of claim 2, wherein, The fixed bracket includes a bracket body and a first bent portion, a second bent portion, and a third bent portion that are bent relative to the outer edge of the bracket body. The first support block is provided with a slot for inserting the first bent portion, the second support block is provided with a first threaded hole for fixing the second bent portion, and the third support block is provided with a second threaded hole for fixing the third bent portion.
4. The vibrational test fixture of claim 3, wherein, The second support block and the third support block are both disposed on the side of the first support block facing away from the first side plate. The first support block has the slot on the side facing away from the first side plate, the second support block has the first threaded hole on the side facing away from the first side plate, and the third support block has the second threaded hole on the side facing away from the first side plate.
5. The vibrational test fixture of claim 2, wherein, The bottom surfaces of the first support block, the second support block, and the third support block are all provided with third threaded holes, and the bottom surface of the base plate facing away from the storage space is provided with countersunk screw holes corresponding to the third threaded holes.
6. The vibrational test fixture of claim 1, wherein, The bottom plate is perpendicular to the first side plate, the bottom plate is perpendicular to the second side plate, and the first side plate is perpendicular to the second side plate.
7. The vibrational test fixture of claim 6, wherein, Both the first side plate and the second side plate are laterally locked to the side of the base plate.
8. The vibrational test fixture of claim 1, wherein, The distance between two adjacent mounting holes is equal to or a multiple of the hole spacing on the vibration testing machine.
9. The vibrational test fixture of claim 3, wherein, The bottom of the support body is provided with multiple through holes, and each of the through holes corresponds to a threaded hole on the bottom of the object to be tested.
