Description

Technical Field

[0001] The utility model relates to the technical field of tooling vibration detection, in particular to a vibration test tooling. Background Art

[0002] Some products generally need to be tested during the R&D stage to prove their reliability. Currently, most related tooling does not have a displacement detection device, and can only compare the positions before and after the test to confirm their relative displacement. If the process cannot be detected, it may lead to the engineering and technical personnel not being able to grasp the true performance of the product, insufficient product verification, and the product may cause trouble to related users after it enters the market. In order to relieve customer troubles, a large amount of funds are also needed to support subsequent product problem troubleshooting and other work.

[0003] Therefore, there is an urgent need for a test fixture that can detect the displacement of related parts during the entire test process, so as to help technicians master the entire test process. Utility Model Content

[0004] The utility model aims to provide a vibration test tool to solve the problems raised in the background technology.

[0005] An embodiment of the present application provides a vibration test tooling, including a fixed base plate, an anti-rotation block and a hydraulic cylinder are respectively installed on the upper end of the fixed base plate, a fork is provided on the sliding sleeve of the anti-rotation block, the other end of the fork is installed on the telescopic end of the hydraulic cylinder, a first displacement sensor assembly is installed at the position where the fork is installed on one end of the hydraulic cylinder, a second displacement sensor assembly is installed on the hydraulic cylinder, and the positions of the first displacement sensor assembly and the second displacement sensor assembly correspond to each other.

[0006] By adopting the above technical solution, when conducting an experiment, the fixed base plate is installed on the vibration equipment, and the hydraulic cylinder is shaken by the vibration equipment. The shaking of the hydraulic cylinder will cause the telescopic rod on the hydraulic cylinder to move in the vertical direction. When the telescopic rod on the hydraulic cylinder moves, it will drive the shift fork to move in the vertical direction. The movement of the shift fork will drive the first displacement sensor assembly to move. When the first displacement sensor assembly is separated from the second displacement sensor assembly, the first displacement sensor assembly and the second displacement sensor assembly will record and detect the displacement value. The above structure can detect the displacement after vibration to further understand the performance of the tooling, thereby improving the accuracy of the tooling experiment detection.

[0007] Optionally, a plurality of mounting holes are provided on the fixed base plate, and the anti-rotation block and the hydraulic cylinder are fixedly connected to the fixed base plate through the mounting holes.

[0008] By adopting the above technical solution, it is convenient to install and disassemble the anti-rotation block and the hydraulic cylinder.

[0009] Optionally, a small gap is provided between the anti-rotation block and the shift fork, and lubricating oil is applied to both the anti-rotation block and the shift fork.

[0010] By adopting the above technical solution, the friction between the anti-rotation block and the shift fork is reduced.

[0011] Optionally, the shape of the anti-rotation block is designed according to the corresponding shift fork.

[0012] By adopting the above technical solutions, the needs under different conditions can be met.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The technical solution of the present application can detect the displacement after vibration by setting up a fixed base plate, an anti-rotation block, a hydraulic cylinder, a fork, a first displacement sensor assembly, a second displacement sensor assembly and a mounting hole, so as to further understand the performance of the tooling, thereby improving the accuracy of the tooling experimental detection.
