Description

Technical Field

[0001] The invention relates to the technical field of damper testing, in particular to a damper test device. Background Art

[0002] A damper is a device that dissipates motion energy by providing resistance to movement. Various dampers (or shock absorbers) have long been used in industries such as aerospace, aviation, military, guns, and automobiles to reduce vibration and dissipate energy. A general damper is mainly composed of a damper body and a test unit. The test unit can be set to a corresponding structural shape according to requirements and is used to connect to corresponding equipment. After the damper is produced and processed, the damper performance needs to be tested.

[0003] The existing Chinese patent application with application publication number CN118464421A discloses a damper loading force test fixture, comprising a base, on which a workbench is arranged; a driving mechanism, which is fixedly mounted on the top of the base, and the bottom of the driving mechanism passes through the top of the base and is fixedly mounted with a loading plate; a damper, which is placed on the workbench; a first control panel, which is arranged on one side of the damper, and the side of the first control panel away from the damper is fixedly connected to the base, and a groove is provided on the first control panel; the invention, by providing a first control panel, a second control panel and a mechanical clamp, can clamp or release the telescopic end of the damper according to the motion trajectory of the loading fixture during the damper loading force test, thereby synchronously correcting the recovery speed of the telescopic end of the damper, so that it can always return to the initial height at the same time, and cyclically perform loading fatigue test under the same loading force and the same frequency, so that the test results are more accurate.

[0004] However, the test device has the following defects when used:

[0005] 1. When testing the performance and durability of the damper, the existing test device needs to apply mechanical force to simulate the actual state of the damper during assembly and use, so as to improve the accuracy of the test. At the same time, in order to improve the stability during the test operation, the damper needs to be clamped and fixed to reduce the probability of the damper moving due to the applied mechanical force. At this time, after each damper test is completed, a lot of time is required to disassemble the damper and replace the damper (the next group of dampers), resulting in low efficiency when testing large batches of dampers;

[0006] 2. When testing the mechanical properties of a damper, the existing testing device can generally only test the performance of one damper at a time, and it is difficult to test multiple dampers at one time, resulting in low efficiency when testing the performance of the damper, and does not meet the factory's requirements for testing large batches of dampers.

On the other hand, when testing the damper, the adjacent horizontal guide cylinders can be away from the test part of the damper to ensure that when testing other dampers, the disassembly and reinstallation of the tested damper (the next group of dampers to be tested) can be carried out simultaneously, further improving the efficiency of testing large batches of dampers;

[0046] 3. In the damper test device, when the damper is clamped and fixed, the distance between the positioning block and the horizontal sliding block for clamping and fixing the damper side can be adjusted by operating the telescopic cylinder, which is convenient for clamping and fixing dampers of different sizes and meets the requirements for testing dampers of different specifications.

[0047] 4. In the damper test device, when the damper is tested (performance and durability), the test rod can be driven by the electric push rod to move horizontally and the test rod can slide inside the horizontal groove through the protrusion to provide horizontal mechanical extrusion force, simulating the actual assembly, use and operation of the damper, so as to ensure that the test results are more accurate when the damper is tested.
