Description

Technical Field

[0001] The utility model relates to the technical field of solar sailboard hinges, in particular to a clamp for a solar sailboard hinge mechanism. Background Art

[0002] After the satellite is launched into the predetermined orbit, in addition to relying on its own batteries for power supply, most of the electricity is obtained by charging the satellite's solar panels to maintain the normal operation of the entire system. Traditional large satellites have complex systems, large size and mass, and their demand for electricity increases accordingly. Therefore, the area of ​​their solar panels is also quite large. They are generally deployed and supported by large and complex truss structures, which are large in size, heavy in weight and complex in structure. Due to reasons such as cost, purpose, and usage requirements, microsatellites are more popular in the rapidly developing civil satellite industry. Due to factors such as size, mass and launch cost, complex truss structures are not suitable for microsatellites. Therefore, hinge structures become necessary components for microsatellite solar panels. The hinge mechanism used to deploy solar panels must be able to open automatically and reliably self-lock in a given position. In order to meet ground testing, it is also necessary to be able to easily release the self-locking requirement at any time;

[0003] When processing the hinge mechanism of a solar panel, the entire mechanism needs to be clamped, but the existing clamps can only clamp one or can only clamp multiple in the same direction, which is inconvenient to operate. In addition, the existing clamps may cause the hinge mechanism to move due to vibration or other reasons during use. In order to solve the above problems, a clamp for the hinge mechanism of a solar panel is proposed. Utility Model Content

[0004] In view of the above existing technical problems, the utility model provides a clamp for a hinge mechanism of a solar sailboard, which is characterized by comprising a base, a limiting pillar, a locking pull plate, a hinge mechanism, a pressure plate, a U-shaped washer, and a locking bolt. The base is provided with a limiting pillar, the base is provided with a locking pull plate, the base is provided with a hinge mechanism, the base is provided with a pressure plate, the pressure plate is provided with a U-shaped washer, and the locking pull plate is provided with a locking bolt;

[0005] Furthermore, the base has a vertical plate, the vertical plate of the base has an opening, the pressure plate passes through the opening of the base, the hinge mechanism has two, which are respectively located on the vertical plate of the base at different angles, each of the hinge mechanisms has two pressure plates, and the pressure plates are in close contact with the hinge mechanism;

[0006] Furthermore, the locking plate has a plurality of openings on its surface, the pressure plate passes through the openings of the locking plate and is connected to the U-shaped washer, and the locking bolt is connected to the locking plate via a thread.

[0007] Beneficial effects of the utility model:

[0008] The utility model can firmly fix the workpiece on the workbench or machine tool by using the base, so that the workpiece will not move or shake during processing, thereby ensuring the processing accuracy and quality; the workpiece can be accurately positioned by using the limit support, thereby ensuring the processing accuracy and production efficiency; the hinge mechanism can be clamped in the base by using the pressure plate, and the hinge mechanism can be clamped by the pressing action of the pressure plate, thereby ensuring that the hinge mechanism is processed in a stable state, and at the same time, the hinge mechanism can be prevented from moving or rotating during the processing, thereby ensuring the processing accuracy and quality; the hinge mechanism can be clamped in the base by using the locking pull plate, thereby ensuring that the hinge mechanism can be processed in a stable state ... When the hinge mechanism is in the form of a hinge, the pressure plate in the base can increase the clamping force of the pressure plate by applying pressure to ensure that the hinge mechanism is more secure and that the two pressure plates are subjected to force at the same time; by using a U-shaped washer, it can adapt to the arc-shaped joint surface, play a buffering and isolating role, and balance the clamping force of the pressure plates at both ends; by using a locking bolt, the workpiece can be prevented from moving, and the locking pull plate is driven backward by the rotational force, and the locking pull plate drives the U-shaped washer, and then the U-shaped washer simultaneously pulls the pressure plates on both sides forward and backward, which plays a role in tightening and loosening the workpiece, avoiding the movement of the hinge mechanism due to vibration or other reasons during the processing.
