[0020] As Figures 1-2 shown, the embodiment provides a fixing and supporting device 100 for the glued lens 30.

[0021] The glued lens 30 comprises a lens 31 and a lens frame 32 surrounding the lens 31, the thickness of the lens frame 32 is less than the thickness of the lens 31, and the lens 31 and the lens frame 32 are adhered by glue 33.

[0022] The fixing and supporting device 100 comprises a base plate 10 and eight adjustable supporting structures 20.

[0023] The base plate 10 is concavely provided with a groove 10a with an opening upward, which can horizontally embed and fix one side of the lens 31. The base plate 10 is also concavely provided with eight inner threaded holes 10b with openings upward, which are evenly arranged around the groove 10a.

[0024] Eight adjustable support structures 20 are evenly arranged around the mirror frame 32, and the adjustable support structures 20 are in one-to-one correspondence with the internally threaded holes 10b.

[0025] The adjustable support structure 20 comprises an adjusting part 21, a supporting part 22, and a spring 23.

[0026] The adjusting part 21 comprises a connecting part 211, a threaded rod 212, and a screw cap 213.

[0027] The connecting part 211 is fixed to the upper surface of the mirror frame 32 by means of a screw A passing through the connecting part 211 and the mirror frame 32, and extends towards the radial outside of the mirror frame 32, and the extended part is denoted as an extended section 211a, and the lower surface of the extended section 211a has an internally threaded screw hole 211b opening downward.

[0028] One end of the threaded rod 212 is matched and screwed into the screw hole 211b, and is fixed vertically downward below the extended section 211a. The threaded rod 212 points downward to the corresponding internally threaded hole 10b.

[0029] The screw cap 213 is a cap-shaped structure opening downward, and has a through hole with an internal thread in the axial direction, and the screw cap 213 is matched and screwed onto the threaded rod 212 through the through hole, and the up-down position of the screw cap 213 can be adjusted by rotating.

[0030] The supporting part 22 is a rod-shaped structure having an external thread at one end, and is matched and screwed into the internally threaded hole 10b, and is fixed vertically upward on the chassis 10. The supporting part 22 is in the same vertical direction as the threaded rod 212, and the two do not contact each other.

[0031] The spring 23 is sleeved on the threaded rod 212 and the supporting part 22, and one end of the spring 23 abuts against the chassis 10, and the other end abuts against the inner top of the screw cap 213. The compression degree of the spring 23 can be adjusted by adjusting the specific position of the screw cap 213 screwed onto the threaded rod 212.

[0032] The use process of the fixed support device 100 of the glued lens:

[0033] Firstly, the glued lens 30 is placed on the chassis 10, and the lens 31 is embedded in the groove 10a and arranged horizontally.

[0034] Subsequently, the adjustable support structure 20 is installed and connected with the chassis 10.

[0035] Then, the rotating cap 213 is rotated, the compression degree of the spring 23 abutting between the rotating cap 213 and the bottom disc 10 is controlled, the indirect elastic force size between the threaded rod 212 and the support part 22 is adjusted, and then the size of the vertical upward support lifting force of the spring 23 indirectly exerted on the lens frame 32 is adjusted. The rotating position of the rotating cap 213 is adjusted, and finally the spring 23 is adjusted to have the same elastic force size as the gravity size of the lens frame 32, so that the stress influence of the lens frame 32 and the glue 33 on the lens 31 due to the self weight can be offset to facilitate the subsequent measurement of the surface shape and the like.

[0036] Effects of the Embodiment

[0037] According to the fixing and supporting device for the cemented lens provided by the embodiment, the cemented lens comprises a lens and a lens frame surrounding the lens, the thickness of the lens frame is smaller than the thickness of the lens, and the lens and the lens frame are connected by the glue. The fixing and supporting device comprises a bottom disc and at least three adjustable supporting structures. The bottom disc is concave and has a groove with an opening facing upward, and the lens can be horizontally embedded in the groove. The adjustable supporting structures are uniformly arranged around the lens frame. Each adjustable supporting structure comprises an adjusting part and a supporting part. The adjusting part extends laterally on the lens frame and is located radially outside the lens frame. The supporting part is arranged on the bottom disc and corresponds to the adjusting part. The supporting part and the adjusting part are indirectly connected by a spring which can be adjusted in compression.

[0038] Therefore, the fixing and supporting device for the cemented lens can adjust the force in the vertical direction between the adjusting part and the supporting part by adjusting the compression length of the spring, so that the adjusting part drives the lens frame to generate an upward force to offset the stress influence of the lens frame and the glue on the lens due to the self weight.

[0039] Further, the bottom disc has a plurality of internal threaded holes with openings facing upward, and the internal threaded holes are uniformly arranged around the groove. The supporting part is a round rod with an external thread at one end. The supporting part is correspondingly matched and screwed into the internal threaded hole to be fixed vertically on the bottom disc. The adjusting part comprises a connecting part, a threaded rod, and a rotating cap. The connecting part is arranged on the upper surface of the lens frame and extends radially outward of the lens frame. The extending part is referred to as an extending segment. The lower surface of the extending segment has a screw hole with an internal thread and an opening facing downward. The threaded rod is correspondingly matched and screwed into the screw hole to be fixed vertically below the extending segment. The threaded rod is in the same vertical direction as the supporting part and does not directly contact the supporting part. The rotating cap is a cover-shaped structure with an opening facing downward. The rotating cap has a through hole with an internal thread in the axial direction. The rotating cap is screwed onto the threaded rod through the through hole, and the position of the rotating cap can be adjusted. The threaded rod and the supporting part are jointly sleeved with a spring. One end of the spring abuts against the bottom disc, and the other end abuts against the inner top of the rotating cap. In this way, the compression degree of the spring can be adjusted by adjusting the specific position of the rotating cap screwed onto the threaded rod, and the vertical force between the supporting part and the threaded rod can be conveniently and quickly adjusted.

[0040] Further, the connecting part is fixed to the upper surface of the frame by screwing through itself and the frame. In this way, the connecting part is designed to be detachable, so that it can be adapted to different sizes of the glued frame, thereby facilitating subsequent measurement.

[0041] Further, the number of adjustable support structures is 8, and every two adjacent adjustable support structures are arranged at an interval of 45° on the radial periphery of the frame. In this way, the force of the support of the frame is more uniform, avoiding uneven force on the frame caused by too few adjustable support structures.

[0042] Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
