Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mirror surface detection, in particular to a low-stress surface shape detection supporting tool with auxiliary support. BACKGROUND

[0002] During the integration of a complex mirror frame, the surface shape change of a lens needs to be monitored in real time to ensure that the surface shape introduction amount of each integration step is actually controlled. However, when the lens surface shape of a mirror frame with a large deviation between the centroid and the geometric center is detected under an interferometer, the mirror frame needs to be fixed on a moving table of the interferometer, and both the mode of the supporting tool and the introduction amount of the lens surface shape during the fixing process and the consistency of the introduction amount of the lens surface shape during each disassembly and fixing need to be controlled.

[0003] The existing lens surface shape detection tool for the mirror frame with a large deviation between the centroid and the geometric center under the interferometer is fixed on the mirror frame and the moving table of the interferometer by screws at both ends. The application reduces the contact area between the supporting leg and the mirror frame and the moving table of the interferometer, improves the flatness and parallelism of the contact surface, reduces the surface shape change of the lens during the screw fastening process, and increases the flexibility of the supporting leg to reduce the stress transmission. However, the flatness of the moving table of the interferometer is limited, and the deformation of the supporting leg will be caused during the screw fastening process, thereby causing the surface shape change of the lens. The above supporting structure design can realize the fixation of the mirror frame, but the supporting structure is not suitable for high requirement mirror frame surface shape detection. The self weight of the mirror frame is too large, and the geometric shape of the mirror frame is irregular, which causes the integrated surface shape of the tool to be too large, and the flexibility of the supporting leg is too high, which brings great difficulty and risk to the processing and support of the large weight mirror frame.

[0004] Therefore, how to avoid the surface shape change of the lens caused by the stress generated when the screw fastens the supporting leg is a technical problem to be solved by the person skilled in the art at present. SUMMARY

[0045] In addition, the support leg 300 is connected with the adapter plate 200 through the holder 400, so that the stress generated by the screw fastening of the support leg 300 can avoid the change of the lens surface, thereby affecting the detection result.

[0046] Preferably, the support leg 300 comprises a support column 310 and a support circular platform 320; the support column 310 is a columnar structure, and the end part can be fixedly connected with the frame 100; the support circular platform 320 is a columnar structure, and is arranged at the end part of the support column 310 away from the frame 100, and the axis of the support circular platform 320 coincides with the axis of the support column 310.

[0047] Specifically, referring to Figure 1 , the support leg 300 has a stepped structure, the upper part with smaller diameter is the support column 310, which is mainly used for fixedly connecting the frame 100 with the lens, and the end part of the support column 310 is provided with a screw hole, so that the frame 100 with the lens can be connected by screws; the lower part is a columnar structure, which is the support circular platform 320, and the support circular platform 320 is clamped by the holder 400 in use, and is a key part for connecting the support leg 300 with the adapter plate 200.

[0048] It should be noted that the support column 310 is a hard support made of steel, and the support circular platform 320 is made of flexible material.

[0049] It can be understood that the support column 310 directly supports the frame 100 with the lens, in order to prevent the change of the surface shape under the action of gravity, and to prevent the test result of the frame 100 from being inaccurate due to the strength problem of the support column 310, the support column 310 is preferably made of rigid material, and in this embodiment, it is preferably made of steel; the support circular platform 320 needs to be clamped by the holder 400, and in order to make the support leg 300 more firmly fixed, the support circular platform 320 is preferably made of flexible material.

[0063] It should be noted that the whole holder 400 is also made of steel material.

[0064] As preferred, the inner wall of the clamping part 420 is provided with an annular protrusion.

[0065] It can be understood that the inner wall of the holder 400 is provided with a narrow protruding circular ring, and the protrusion is mainly to reduce the contact area between the holder 400 and the positioning pin 600, so as to avoid the occurrence of the inclination deformation of the supporting leg 300 in the fastening process of the holder 400, which causes a large surface shape introduction.

[0066] As preferred, the supporting leg 300 and the holder 400 are each provided with three.
