Description

Technical Field

[0001] The utility model relates to the technical field of aiming sight impact testing, in particular to a test bench for aiming sight impact testing. Background Technique

[0002] The purpose of conducting an impact test on an aiming sight is to evaluate its performance stability and reliability under extreme environments.

[0003] The test bench for aiming sight impact testing is a test device that simulates the impacts and vibrations that an aiming sight may encounter during actual use. By simulating impacts of different intensities and frequencies, it can detect the structural strength, seismic resistance performance, optical performance, and working stability of electronic components of the aiming sight.

[0004] Currently, to ensure the ex-factory quality of products, some manufacturers conduct impact tests on all aiming sights before leaving the factory. For an aiming sight impact test bench with the prior art publication number CN221078002U, it includes a machine base. A protective frame is fixedly connected to the top of the machine base. A first motor is fixedly connected to the top of the machine base. One end of the output shaft of the first motor is fixedly connected to a coupling. A lead screw is fixedly connected to the outer wall of the right side of the coupling. A threaded block is threadedly sleeved on the outer wall of the lead screw.

[0005] Although this test bench expands the test application range, during the actual operation process, when the aiming sight undergoes the initial optical axis detection and then starts the impact test, the worker opens the fixture for placement operation, then fixes the aiming sight through the fixture, and then conducts the test. After waiting for a certain number of tests, the test bench stops. It is necessary to open the fixture again to take out the detected aiming sight to observe the optical axis offset. After the end, a new aiming sight is tested. Since the entire process requires sequential operations, the test efficiency of a single aiming sight is relatively low, affecting the aiming sight impact test efficiency. Therefore, improvements are proposed. Content of the Utility Model

[0033] Working principle: When a primary impact test is completed, the servo motor 7 drives the driving gear 8 to rotate. The driving gear 8 drives the driven gear 10 to rotate. The driven gear 10 drives the turntable 3 to rotate 180 degrees, moves the sighting scope after the test is completed to the loading and unloading station, moves the sighting scope to be tested to the test station, and then performs a test operation on the sighting scope to be tested. At the same time, the worker opens the sighting scope fixture 5, removes the sighting scope after the test is completed, and then detects its optical axis offset. After completion, the optical axis of the sighting scope to be tested is detected, and then it is placed on the sighting scope fixture 5 and then fixed. Wait until the number of impacts of the sighting scope being tested reaches a certain number, the servo motor 7 drives the turntable 3 to rotate 180 degrees again through various components, and then repeat the above operations until all the sighting scopes are tested; when it is necessary to replace the sighting scope fixture 5, turn the hand-tightening bolt 6 clockwise. The hand-tightening bolt 6 drives the active block 14 and the locking block 15 to move into the sliding groove 13 until the locking block 15 enters the sliding groove 13, and then push the sighting scope fixture 5 to move, so that the auxiliary protrusion 17 is separated from the assembly groove 21, and then remove the sighting scope fixture 5. Then place the mounting seat 20 of the new sighting scope fixture 5 in the mounting groove 16, and then turn the hand-tightening bolt 6 counterclockwise. The hand-tightening bolt 6 drives the active block 14 and the locking block 15 to move towards the side of the mounting seat 20 until the locking block 15 and the auxiliary protrusion 17 are both completely inserted into the corresponding assembly grooves 21, then the replacement operation is completed.
