Description

Technical Field

[0001] This utility model belongs to the field of engineering technology and relates to test devices, specifically a test device for a fixed release mechanism. Background Technology

[0002] Fixed-release mechanisms are widely used in aerospace, shipbuilding, industrial automation, and other fields, primarily for satellite release, munitions delivery, and material pylon deployment. They work by using a locking device to reliably secure the object to a carrier device. Upon receiving a trigger signal, the release mechanism quickly and reliably releases the object. Due to the complex operating conditions in these applications, various scenarios exist. Whether the mechanism can operate stably and whether its fixing and releasing performance will be affected requires load and trigger tests to quickly adapt to the specific requirements of different customers and usage scenarios.

[0003] In response to this situation, there is an urgent need to develop a test device for a fixed release mechanism, which can be used to test the performance of the mechanism in real-world application scenarios during the design, manufacturing, and production processes. This will help to optimize and improve the mechanism to meet the needs of actual use. Utility Model Content

This testing device is structurally stable and fully functional. On one hand, it can simulate the fixed condition of the fixed release mechanism on a carrier device and perform load tests under different loads; on the other hand, it can receive a trigger signal to complete trigger tests on the fixed release mechanism.

[0005] This utility model is achieved by the following technical solution: a fixed release mechanism test device, including a fixing device and a load simulation device.

The plane of the small curved beam is fixedly connected to the plane of the large curved beam, that is, the elevation of the small curved beam is parallel to the elevation of the large curved beam. The simulated carrier connector is fixedly connected to the elevation of the small curved beam. The thrust stop is fixedly installed on the plane of the large curved beam, and the thrust stop is located between the elevation of the large curved beam and the elevation of the small curved beam.

The simulated load is fixedly installed on the connecting block.

[0008] In a further preferred embodiment, the plane of the small curved section is fixed to the plane of the large curved section by screws, and its position is adjustable to accommodate fixed release mechanisms of different specifications.

[0009] Furthermore, the back of both the large and small curved zithers are equipped with reinforcing ribs.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example: Reference Figure 1-4 The device shown is a test apparatus for a fixed release mechanism, comprising a fixing device and a load simulation device. The fixing device mounts the load simulation device on the fixed release mechanism. The rear end of the simulated load is connected to a hydraulic cylinder, and the load force is simulated by applying hydraulic pressure to the hydraulic cylinder. Simultaneously, after a release signal is applied to the hydraulic cylinder, the simulated load can still maintain the load force, thus realizing the trigger test of the fixed release mechanism.

[0028] 1. Fixing device

[0029] refer to Figure 2 The fixing device shown includes a large curved bracket 1, a small curved bracket 2, and a thrust stop 4. The plane of the small curved bracket 2 is fixedly connected to the plane of the large curved bracket 1 by screws, that is, the facade of the small curved bracket is parallel to the facade of the large curved bracket, and its position is adjustable to accommodate fixing and releasing mechanisms of different specifications. A simulated carrier connector 5 is fixedly connected to the facade of the small curved bracket 2; the thrust stop 4 is fixedly installed on the plane of the large curved bracket 1, and the thrust stop 4 is located between the facade of the large curved bracket 1 and the facade of the small curved bracket 2.

[0030] Furthermore, the back of the large curved zither 1 and the small curved zither 2 are respectively provided with reinforcing ribs to prevent the vertical surfaces of the large curved zither 1 and the small curved zither 2 from bending to both sides.

[0031] 2. Load simulation device

[0032] refer to Figure 3 The load simulation device shown includes a hydraulic cylinder 3, a connecting block 7, and a simulated load 8. The connecting block 6 and the simulated load 7 are connected by a vertical slide rail 9 installed on the vertical surface of the large curved plate 1, and a slider 8 that can slide freely is installed on the slide rail 9. The connecting block 6 is fixedly installed on the slider 8. The hydraulic cylinder 3 is installed on the vertical surface of the large curved plate 1, and the piston rod end of the hydraulic cylinder 3 is connected to the top of the connecting block 6. The simulated load 7 is fixedly installed on the connecting block 6.

[0033] At the same time, as referenced Figure 4 The hydraulic cylinder 3 shown includes a cylinder body 31, a piston rod 32, and a tail cover 34; and a limiting block 33 is provided inside the cylinder body to limit the extension stroke of the piston rod.

[0034] Furthermore, the end of the piston rod 3 is connected to the top of the connecting block 7 via a ball joint.

[0035] In addition, two sets of sliders 8 can be installed on the slide rail 9, which are connected to the connecting block 7.

[0036] Furthermore, the simulated load 7 is connected to the connecting block 6 via screws.
