Description

Technical Field

[0001] This invention relates to the field of astronomical telescope processing technology, specifically to a clamping fixture for processing astronomical telescope lenses. Background Technology

[0002] Astronomical telescopes are the primary tools for observing celestial bodies and capturing information about them. Since Galileo built the first telescope in 1609, telescopes have continuously evolved, from optical bands to all bands, from ground-based to space-based observations, with increasingly powerful observation capabilities and the ability to capture more and more celestial information.

[0003] When processing astronomical telescope lenses, they need to be fixed in place by a clamp before surface treatment. However, traditional astronomical telescope lens clamping fixtures mostly use screws for fixing. Screw fixing is inconvenient for installation and disassembly, and it is impossible to make fine adjustments to the lens after fixing. Each time the lens distance is adjusted, the screws need to be removed, which is cumbersome and inconvenient. Therefore, a new astronomical telescope lens processing clamping fixture is proposed to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a clamping fixture for processing astronomical telescope lenses. It has advantages such as quick distance fine-tuning and ease of use. It solves the problems of traditional astronomical telescope lens clamping fixtures that mostly use screws for fixing. Screw fixing is inconvenient for installation and disassembly, and it is impossible to fine-tune the lens after fixing. Each time the lens distance is adjusted, the screws need to be removed, which is cumbersome and inconvenient to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping fixture for processing astronomical telescope lenses, comprising:

[0006] The mounting base has a mounting hole on its left side, a mounting groove on its right side, a threaded hole on the upper left side of the mounting base, and an insertion hole on the upper left side of the mounting base. A limit ring is fixedly installed inside the insertion hole.

[0007] The clamping seat has a through hole on its left side, a connecting screw hole on the upper left side of the clamping seat, a clamping groove on its right side, limit grooves on the top and bottom of the right side of the clamping seat inside the clamping groove, a through hole on the upper left side of the clamping seat, and a slide rail fixedly installed on the rear side wall of the clamping seat to the right of the through hole, with a screw sleeve fixedly installed on the inner side of the slide rail.

[0008] A clamping post is inserted into the through hole, and a permanent magnet is fixedly installed on the right side of the clamping post;

[0009] A clamping piece, wherein an iron sheet is fixedly installed on the left side of the clamping piece;

[0010] An adjusting screw is threaded onto the left side of the threaded hole;

[0011] An adjusting cylinder is rotatably installed inside the insertion hole. A telescopic rod is inserted into the right end of the adjusting cylinder, and a lead screw is fixedly installed at the right end of the telescopic rod. Sliding grooves are provided on both the inner bottom wall and the inner top wall of the adjusting cylinder, and sliders are fixedly installed at the top and bottom of the telescopic rod.

[0012] Preferably, the clamping seat is inserted into the interior of the mounting groove, and the threaded hole is located above the insertion hole.

[0013] Preferably, the right end of the adjusting screw passes through the threaded hole and extends into the interior of the connecting screw hole, and the adjusting screw is threadedly connected to both the connecting screw hole and the threaded hole.

[0014] Preferably, the clamping post is located inside the clamping seat, and the clamping piece is magnetically attracted to the right end of the clamping post by an iron sheet.

[0015] Preferably, the right end of the adjusting drum passes through the insertion hole and the through hole in sequence and extends into the interior of the slide rail.

[0016] Preferably, the outer surface of the adjusting drum is provided with a rotating groove, and the limiting ring is rotatably installed inside the rotating groove.

[0017] Preferably, the lead screw is threaded into the inside of the screw sleeve, and the top and bottom of the screw sleeve are respectively fixedly connected to the inner wall of the slide rail.

[0018] Preferably, a top cap is fixedly installed at the right end of the lead screw, and the two sliders are slidably installed inside the two grooves respectively.

[0019] Preferably, the length of the lead screw is greater than the length of the slide rail, the diameter of the clamping plate is greater than the diameter of the clamping post, and the clamping plate is a "T" shaped rubber pad.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] 1. This astronomical telescope lens processing clamping fixture uses a clamping plate. When processing the astronomical telescope lens, the clamping plate is inserted into the lens hole, and the lens is placed on the right side of the clamping seat. The outer edge of the lens is inside the limiting groove. At this time, the iron plate on the left end of the clamping plate will be attracted to the clamping post, thereby fixing the lens by a permanent magnet. Using a magnet makes installation and disassembly more convenient, and the attraction is firm and will not easily shake, which will not affect the normal processing of the lens and makes it more convenient to use.

[0022] 2. This astronomical telescope lens processing clamping fixture, through the setting of adjusting screws and adjusting cylinders, allows for adjustment of the position of the clamping seat within the mounting base when adjusting the lens position. First, the adjusting screw can be rotated, causing it to push the clamping seat to the right, thus slightly adjusting the lens position to the left. Simultaneously, the adjusting cylinder can be rotated, rotating inside the insertion hole. During this rotation, the cylinder drives the lead screw to rotate via the telescopic rod. When the clamping seat moves to the right, the telescopic rod will be extended to the right. At this time, the lead screw rotates, causing the threaded sleeve to rotate. Since the threaded sleeve is fixed inside the slide rail, it will move to the left on the outer surface of the lead screw. This movement will push the clamping seat to the left to reset, thereby slightly adjusting the lens position to the left. During this process, the adjusting screw will rotate counterclockwise. The position of the lens on the clamping fixture can be freely and quickly adjusted without disassembling the lens. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-5 This embodiment of a astronomical telescope lens processing clamping fixture includes:

[0031] Mounting base 1, mounting base 1 has mounting hole 2 on the left side, mounting groove 12 on the right side, threaded hole 13 on the upper left side of mounting base 1, insertion hole 14 on the upper left side of mounting base 1, and a limit ring 15 is fixedly installed inside the insertion hole 14.

[0032] The clamping seat 5 has a through hole 6 on its left side, a connecting screw hole 7 on the upper left side of the clamping seat 5, a clamping groove 16 on its right side, a limit groove 17 on the top and bottom of the right side of the clamping seat 5 inside the clamping groove 16, a through hole 18 on the upper left side of the clamping seat 5, and a slide rail 19 fixedly installed on the rear side wall of the clamping seat 5 to the right of the through hole 18. A screw sleeve 20 is fixedly installed on the inner side of the slide rail 19.

[0033] The clamping post 8 is inserted into the through hole 6, and a permanent magnet 9 is fixedly installed on the right side of the clamping post 8.

[0034] A clamping plate 10 is provided, and an iron plate 11 is fixedly installed on the left side of the clamping plate 10.

[0035] Adjusting screw 3 is threaded on the left side of threaded hole 13;

[0036] The adjusting cylinder 4 is rotatably installed inside the insertion hole 14. The right end of the adjusting cylinder 4 is connected to the telescopic rod 21. The right end of the telescopic rod 21 is fixedly installed with the lead screw 22. The inner bottom wall and inner top wall of the adjusting cylinder 4 are both provided with sliding grooves 23. The top and bottom of the telescopic rod 21 are both fixedly installed with sliders 24.

[0037] In this embodiment, the clamping seat 5 is installed inside the mounting groove 12, the threaded hole 13 is designed above the insertion hole 14, and the adjusting screw 3 passes through the threaded hole 13 and enters the interior of the connecting screw hole 7. The two are connected by threads so that the clamping seat 5 can be moved to the right by rotating the adjusting screw 3.

[0038] In this embodiment, the clamping post 8 is disposed inside the clamping base 5, and the clamping piece 10 and the clamping post 8 are magnetically attracted by the iron piece 11 and the permanent magnet 9, thereby fixing the lens.

[0039] In this embodiment, the design of the limiting ring 15 ensures that the adjusting cylinder 4 will not shift left or right during rotation, and a limiting groove is provided on the outer surface of the adjusting cylinder 4.

[0040] In this embodiment, the lead screw 22 is threadedly connected to the screw sleeve 20, the screw sleeve 20 is installed inside the slide rail, and a top cap for limiting is installed at the right end of the lead screw 22. The slider 24 can move left and right inside the slide groove 23. The length of the lead screw 22 is designed to be greater than the length of the slide rail to ensure that the screw sleeve 20 can be displaced normally.

[0041] With the above technical solution, when processing the astronomical telescope lens, the clamping plate 10 is inserted into the lens hole, and the lens is placed on the right side of the clamping base 5. The outer edge of the lens is inside the limiting groove 17. At this time, the iron plate 11 at the left end of the clamping plate 10 will be attracted to the clamping post 8, thereby fixing the lens by the permanent magnet 9. Using a magnet makes it easier to install and remove the lens, and the attraction is firm and will not easily shake, which will not affect the normal processing of the lens and makes it more convenient to use.

[0042] In this embodiment, by setting the adjusting screw 3 and the adjusting cylinder 4, the position of the clamping seat 5 inside the mounting base 1 can be adjusted when adjusting the lens position. First, the adjusting screw 3 can be rotated, causing the adjusting screw 3 to push the clamping seat 5 to the right, so that the position of the lens is slightly adjusted to the left. At the same time, the adjusting cylinder 4 can also be rotated. The adjusting cylinder 4 will rotate inside the insertion hole 14. During the rotation, the telescopic rod 21 will drive the lead screw 22 to rotate. When the clamping seat 5 moves to the right, the telescopic rod 21 will be driven to extend to the right. At this time, the lead screw 22 rotates, causing the screw sleeve 20 to rotate. Since the screw sleeve 20 is fixed inside the slide rail 19, the screw sleeve 20 will move to the left on the outer surface of the lead screw 22. The movement will push the clamping seat 5 to the left to reset, thereby slightly adjusting the lens to the left. During this process, the adjusting screw 3 will rotate counterclockwise. The position of the lens on the clamping fixture can be freely adjusted without disassembling the lens, which is convenient and quick.
