Description

Technical Field

[0001] This utility model relates to the field of astronomical telescopes, and in particular to a structure for rapid optical axis correction of astronomical telescopes. Background Technology

[0002] In the structural design of astronomical telescopes, conventional telescope objectives are usually fixed at the front of the telescope body and cannot be adjusted. Due to errors in the manufacturing and assembly precision of the telescope body and focusing mount, the actual optical axis of the objective will be tilted, resulting in aberrations. The aberrations caused by optical axis misalignment are particularly noticeable in sensitive optics. Currently, the optical axis adjustment solutions for objective lenses on the market often use a screw-push-pull flange structure. A screw used to "push" connects the objective to the telescope body to create a push-out gap, and a screw used to "pull" tighten the telescope body and objective together to prevent wobbling. This structure often exhibits certain inconveniences in practical use, such as the adjustment process being too cumbersome, requiring simultaneous adjustment of the "push" and "pull" screws; the adjustment method being non-linear, allowing verification of the adjustment results only after completion, making it impossible to observe changes in real time during the adjustment process; and the screw pre-tightening usually only being ensured by thread-locking adhesive, which can easily cause the screws to loosen with repeated adjustments. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a rapid optical axis correction structure for an astronomical telescope, comprising a telescope body, an objective lens assembly, a tension spring, and an adjusting screw. The telescope body has a threaded hole, into which a tension spring fixing screw is fixed. A hook at one end of the tension spring fits into an opening in the tension spring fixing screw, and the other end is fixed to the objective lens assembly via a tension spring limiting screw. The objective lens assembly is equipped with an adjusting sleeve, through which the adjusting screw contacts a wear-resistant washer on the telescope body. The telescope body and the objective lens assembly are not directly connected; they are connected via the tension spring and the adjusting screw. The threaded hole on the lens body is parallel to the lens body's axis. The objective lens assembly also has threaded holes radially. Using a specific tool, the tension spring is pulled out, and the tension spring limiting screw is passed through the threaded hole on the objective lens and through the tension spring hook. The preload provided by the tension spring pulls the lens body and objective lens assembly tightly together. Multiple tension springs are evenly distributed to ensure sufficient and even tension. The objective lens assembly has an adjusting sleeve parallel to the axis, and a wear-resistant shim is placed on the lens body. The adjusting screw passes through the adjusting sleeve and contacts the wear-resistant shim. During optical axis correction, a wrench is used to adjust the adjusting screw, resisting the tension spring force, creating a certain gap between the lens body and the objective lens assembly, thereby changing the angle of the objective lens assembly and achieving optical axis correction.

[0004] The above-mentioned technical solution of this utility model has the following beneficial technical effects: There is always a spring tension between the objective lens and the telescope body; increasing or decreasing the tilt gap only requires adjusting the "push" screw, ensuring the spatial stability of the objective lens assembly throughout the adjustment process, and guaranteeing that adjustment and observation can be performed simultaneously. It enables rapid correction of the optical axis of the astronomical telescope objective lens, allowing for convenient and quick adjustment of the objective lens angle to correct optical axis deviation.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0011] like Figure 1-3As shown, a rapid optical axis correction structure for an astronomical telescope is provided, comprising a telescope body 1, an objective lens group 5, a tension spring 3, and an adjusting screw 7. The telescope body 1 has a threaded hole, and a tension spring fixing screw 2 is fixed within this hole. One end of the tension spring 3 has a hook that fits into an opening in the tension spring fixing screw 2, and the other end is fixed to the objective lens group 5 via a tension spring limiting screw 4. The objective lens group 5 is equipped with an adjusting sleeve 6, and the adjusting screw 7 passes through the adjusting sleeve 6 and contacts a wear-resistant washer 8 on the telescope body 1. The telescope body 1 and the objective lens group 5 are not directly connected; they are connected by the tension spring 3 and the adjusting screw 7. The threaded hole of the lens body 1 is parallel to the axis of the lens body 1. The objective lens group 5 also has a threaded hole radially. Using a specific tool, the tension spring 3 is pulled out, and the tension spring limiting screw 4 is passed through the threaded hole on the objective lens group 5 and through the hook of the tension spring 3. Thus, the preload provided by the tension spring 3 pulls the lens body 1 and the objective lens group 5 tightly together. Multiple tension springs 3 are evenly distributed to ensure sufficient and even tension. The objective lens group 5 is equipped with an adjusting sleeve 6 parallel to the axis, and the lens body 1 is equipped with a wear-resistant shim 8. The adjusting screw 7 passes through the adjusting sleeve 6 and contacts the wear-resistant shim 8. During optical axis correction, a wrench is used to adjust the adjusting screw 7, resisting the tension of the tension spring 3, creating a certain gap between the lens body 1 and the objective lens group 5, thereby changing the angle of the objective lens group 5 and achieving the purpose of optical axis correction.
