Description

Technical Field

[0001] The utility model relates to the technical field of optical reflectors, in particular to a swing mirror support. Background Art

[0002] The reflector is a key component of the reflective optical system, and the reflector support technology is one of the most critical technologies in the engineering application of large-aperture reflectors.

[0003] Reflectors include two structural forms: with and without shaft systems. The reflector with shaft system adopts the traditional mechanical shaft system, which drives the deflection of the reflector by driving the mechanical shaft, and has the characteristics of a large range of motion. However, the support design of the reflector must take into account the harsh environmental conditions such as gravity, temperature, ground installation and adjustment, launch vibration and overload, in order to ensure the surface accuracy of the reflector and the imaging quality of the telescope.

[0004] The support structure of the reflector needs to be lightweight to reduce the impact of deformation due to its own weight. While lightweighting the design, it is also necessary to consider improving the absolute rigidity of the structure. Since lightweight design will cause a decrease in the specific rigidity of the structure, the sensitivity of the mirror to the support stress is also increasing rapidly.

[0005] In addition, the swing mirror deflects under the drive of the driving shaft, and the position of the swing mirror changes at any time. Factors such as its structural stability, control accuracy, dead weight, and temperature will affect the surface accuracy of the reflector and the imaging quality of the telescope. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a swing mirror support which is lightweight and has strong structural stability.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a swing mirror support, including a mounting base, a tubular positioning base is provided at the center position of the back side of the mounting base, the top of the positioning base is open, and the bottom extends to the surface of the mounting base; a plurality of supporting ribs are distributed on the outer side of the positioning base, and the supporting ribs include a main supporting rib located in the middle position and distributed in a grid shape, and a left supporting rib and a right supporting rib located at the left and right sides; the heights of the main supporting ribs are consistent, and a main supporting surface parallel to the surface of the mounting base is formed on the top surface of the main supporting ribs; the left supporting ribs and the right supporting ribs are symmetrically arranged, and the left supporting ribs and the right supporting ribs are wedge-shaped plates, and the height of the wedge-shaped plates gradually decreases from one end close to the middle position to one side;

[0008] The front and rear sides of the main support surface are also provided with mounting sockets, and the mounting sockets include a first bonding surface and a second bonding surface. The first bonding surface is coplanar with the surface of the mounting substrate, and the outer wall of the outermost main support rib coincides with the second bonding surface.

[0009] As a preferred technical solution, the mounting substrate gradually narrows from the middle position to both sides.

[0010] As a further improvement, the left supporting rib plate and the right supporting rib plate located at the outermost sides are inclined inwards as the two sides of the mounting base plate become narrower.

[0011] As a further improvement, a first rib reinforcement block is provided between two adjacent left supporting ribs or right supporting ribs.

[0012] As a preferred technical solution, a plurality of first positioning blocks are distributed on the side surface of the mounting substrate.

[0013] As a preferred technical solution, a plurality of second positioning blocks are distributed on the main supporting surface.

[0014] As a preferred technical solution, a plurality of mounting holes are provided on the second joint surface.

[0015] As a preferred technical solution, a "cross"-shaped bottom reinforcement block is provided at the bottom of the positioning base.

[0016] Due to the adoption of the above technical scheme, the beneficial effects of the utility model are as follows: the utility model sets a positioning base as a reference point for the installation position, the installation position is clear and precise, the installation accuracy of the reflector is improved, and a main support rib plate and left and right support rib plates are set on the back of the installation base, so as to realize the lightweight design of the installation base, and at the same time improve the specific stiffness of the support structure and enhance the stability of the equipment installation; because the left and right support rib plates are wedge-shaped plates, under the premise of further reducing weight, interference between the two sides of the installation base and other components is effectively avoided.

[0017] Since the mounting base gradually narrows from the middle position to both sides, the left supporting rib plate and the right supporting rib plate narrow inward along the two sides of the mounting base, so that the mounting base as a whole forms a ship-shaped shape, which reduces the volume of the mounting base, reduces the weight, and makes the transition of the side lines on both sides of the mounting base smoother, thereby avoiding damage caused by interference and collision with other components to a limited extent.
