Description

Technical Field

[0001] The invention relates to the technical field of interlocking connection between spliced ​​structures to enhance overall rigidity, and in particular to an interlocking electric pin between spliced ​​optical mirror support structures. Background Art

[0002] Most of the electric pin structures currently designed and produced have problems of poor matching accuracy and poor stability, and fail to strictly ensure that the relative position relationship between the interlocking structural parts remains unchanged.

[0003] The project involved is a large lightweight spliced ​​optical mirror with high rigidity in the unfolded state. Even if there is a height difference in the support structure of the spliced ​​optical mirror, the relative position of the mirror surface will not be changed due to the insertion of the pin rod into the pin hole. Therefore, a new type of interlocking electric pin must be designed for interlocking between the sub-mirror support structures, which can enhance the overall rigidity of the spliced ​​optical mirror without generating additional force to affect the relative position relationship between the spliced ​​optical mirrors. Summary of the invention

[0004] The technical problem to be solved by the present invention is: to overcome the shortcomings of the prior art and provide an interlocking electric pin between the support structures of a spliced ​​optical mirror. The structure has the characteristics of simple structure and high reliability, and solves the problem of effectively locking the sub-mirror support structures and keeping the position relationship of the mirror surfaces between the sub-mirrors unchanged.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: an interlocking electric pin between the support structures of the spliced ​​optical mirror, comprising: an electric pin assembly and a square pin hole seat, wherein the electric pin assembly comprises: a driving motor; an electric pin assembly fixing seat, the electric pin assembly is fixed to the spliced ​​optical mirror support structure on one side through the electric pin assembly fixing seat; a first fixing member, used to fix the electric pin assembly to the electric pin assembly fixing seat; a locking in place switch, used to judge whether the pin rod is in place when it is engaged or disengaged; a second fixing member, used to lock the in place switch and the fixing of the electric pin assembly fixing seat ; The pin rod is fixed together with the screw rod and is used to cooperate with the square pin hole seat; the screw rod is fixed to the drive motor through a coupling; the coupling is used to combine the screw rod and the drive motor to realize the telescopic movement of the pin rod, wherein the drive motor rotates the screw rod through the coupling to drive the pin rod to telescopic movement, thereby realizing the interference fit and disengagement with the square pin hole seat; the elastic retaining ring is used to limit the axial movement of the screw rod; the third fixing piece is used to fix the drive motor to the electric pin fixing seat; the square pin hole seat is fixed on the support structure of the spliced ​​optical mirror on the other side, and is used to cooperate with the pin rod.

[0006] The principle of the present invention is: an interlocking electric pin between the support structures of a spliced ​​optical mirror, the structure includes an electric pin assembly and a square pin hole seat, wherein the electric pin assembly includes a driving motor, an electric pin assembly fixing seat, a locking switch, a spherical pin rod, a screw rod, an elastic retaining ring, and a coupling. The driving motor drives the screw rod to rotate through the coupling, thereby realizing the telescopic movement of the spherical pin rod, achieving interference fit and disengagement with the square pin hole seat, and the locking switch determines whether it is in place.

[0007] In order to enhance the overall rigidity of the spliced ​​optical mirror without generating additional force to affect the relative position relationship between the mirror surfaces, the pin hole is designed as a square hole, and the top structure of the spherical pin rod is designed as a spherical surface. If there is a height difference in the mirror support structure, the relative position of the mirror surface will not be changed due to the insertion of the spherical pin rod into the pin hole. And only one direction of displacement is constrained, and no force in other directions will be generated to affect the spliced ​​mirror surface shape.

[0008] Furthermore, the spherical pin has a protrusion for cooperating with an in-place sensor to determine whether the spherical pin is in place when engaged or disengaged. After it is in place, the drive motor stops working to ensure that the spherical pin can reliably engage with and disengage from the pin hole.

[0009] The beneficial effects of the present invention compared with the prior art are as follows:

[0010] (1) The present invention overcomes the deficiencies of the prior art and provides a novel folding and unfolding mechanism structure which is simple in structure and safe and reliable.

[0011] (2) The present invention solves the problem of improving the rigidity of a large lightweight spliced ​​optical primary mirror in its unfolded state.

[0012] (3) The present invention has specially designed the pin rod and the pin hole. Even if there is a height difference in the sub-mirror support structure, the interlocking electric pin can be effectively inserted into the pin hole, thereby enhancing the overall rigidity of the spliced ​​optical mirror without generating additional force that affects the relative position relationship between the spliced ​​optical mirrors.

[0020] The present invention discusses an interlocking electric pin structure. When the spliced ​​optical mirror is unfolded into place, in order to enhance the overall rigidity of the spliced ​​optical mirror body, the electric pin and the pin hole need to be interference fit.

For cooperating with the square pin hole seat 17; the screw 11 is fixed to the drive motor 1 through the coupling 13; the coupling 13 is used to combine the screw 11 and the drive motor 1 to realize the telescopic movement of the pin 10, wherein the drive motor 1 rotates the screw 11 through the coupling 13 to drive the pin 10 to telescopic movement, thereby realizing the interference fit and disengagement with the square pin hole seat 17; the elastic retaining ring 12 is used to limit the axial movement of the screw 11; the third fixing piece is used to fix the drive motor 1 and the electric pin assembly fixing seat 2; the square pin hole seat 17 is fixed on the support structure of the spliced ​​optical mirror on the other side, for cooperating with the pin 10.

[0022] In one embodiment, the first fixing member includes a hexagon socket screw 3, a flat washer 4, and a spring washer 5. The specific means of fixing the electric pin assembly on the electric pin assembly fixing seat 2 by combining the hexagon socket screw 3, the flat washer 4, and the spring washer 5 can be a method of tightening the screws.

[0023] In one embodiment, the second fixing member includes a screw 7, a flat washer 8, and a spring washer 9.

[0026] In one embodiment, the pin hole in the square pin hole seat 17 is designed to be square, so that when the pin rod 10 is inserted into the square pin hole seat 17 in the locked state, the displacement in one direction is limited without any constraint in other directions. In this way, the relative position relationship between the spliced ​​mirror surfaces can be ensured while avoiding the generation of forces in additional directions that affect the surface shape accuracy of the spliced ​​surface.
