Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a fixing device for optical filter production. Background Technology

[0002] Optical filters are optical devices used to selectively transmit light of specific wavelengths or block light of other wavelengths. They are widely used in optical systems, including cameras, microscopes, laser devices, and spectrometers.

[0003] Traditional optical filter fixing devices consist of a base plate, two fixing plates, and two limiting rods. Their working principle involves placing the filter on the base plate and using the fixed plates and limiting rods to constrain horizontal displacement. However, this fixing system has significant limitations: because all positioning elements are fixedly installed and their relative positions are not adjustable, the entire fixture must be replaced when processing filters of different sizes and specifications. Therefore, this solution proposes a fixing device for optical filter production to address these issues. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-5 Shown:

[0029] Example 1:

[0030] A fixture for manufacturing optical filters, comprising:

[0031] Bracket 1;

[0032] Fixing block 2 is set on the top of bracket 1, and a limiting groove 201 is provided on the top of fixing block 2;

[0033] The clamping block 3 is inserted into the inside of the limiting groove 201. The bottom of the clamping block 3 is provided with a moving component 5 for moving the position of the clamping block 3. A connecting component 6 is provided at the connection between the clamping block 3 and the moving component 5.

[0034] The limiting plate 4 is inserted into the limiting groove 201. A driving component 7 for moving the position of the limiting plate 4 is provided at the connection between the limiting plate 4 and the fixing block 2.

[0035] It should be noted that during use, the moving component 5 drives the two clamping blocks 3 to move, so that the distance between the two clamping blocks 3 is adapted to the width of the optical filter. Then, the driving component 7 drives the limiting plate 4 to move, so that the distance between the limiting plate 4 and the inner wall of the back of the limiting groove 201 is adapted to the thickness of the optical filter, thereby enabling the device to be used for optical filters of different widths and thicknesses.

[0036] Specifically, the connecting component 6 includes a connecting block 601 fixedly connected to the bottom of the clamping block 3, and a connecting groove 602 is provided on the inner wall of the bottom end of the limiting groove 201, with the connecting block 601 inserted into the inside of the connecting groove 602.

[0037] It should be noted that the opening of the connecting groove 602 is adapted to the setting of the connecting block 601, so that the connecting block 601 can slide inside the connecting groove 602.

[0038] Specifically, mobile component 5 includes:

[0039] Sliding block 502 is fixedly connected to the bottom end of connecting block 601;

[0040] A double-ended screw 504 is threadedly inserted into the middle of the sliding block 502;

[0041] The first torsion cap 505 is fixedly connected to one end of the bidirectional screw 504.

[0042] Specifically, the bottom of the fixed block 2 has a cavity 503, the sliding block 502 is inserted into the cavity 503, and the bidirectional screw 504 is inserted into the inner wall of one side of the cavity 503.

[0043] Specifically, a fixed bearing 501 is fixedly connected to the inner wall on the other side of the cavity 503, and the fixed bearing 501 is sleeved on the other end of the bidirectional screw 504.

[0044] It should be noted that the cavity 503 is adapted to the sliding block 502, allowing the sliding block 502 to slide inside the cavity 503. The horizontal and longitudinal cross sections of both the cavity 503 and the sliding block 502 are square, preventing the sliding block 502 from rotating inside the cavity 503. The threads on the bidirectional screw 504 are symmetrically arranged from the middle. The number of sliding blocks 502 is the same as the number of clamping blocks 3, and the two sliding blocks 502 are respectively connected to the threads on both sides of the bidirectional screw 504. The fixed bearing 501 is an existing ball bearing, which connects the bidirectional screw 504 and the cavity 503. The fixed bearing 501 adjusts the position of the bidirectional screw 504 without affecting its rotation.

[0045] Furthermore, when it is necessary to move the position of the clamping block 3, the first torsion cap 505 drives the bidirectional screw 504 to rotate. The rotating bidirectional screw 504 drives the two sliding blocks 502, which are threaded to it and cannot rotate, to move in different directions, thereby adjusting the position of the clamping block 3.

[0046] Example 2:

[0047] Drive component 7, applied to the fixing device in one embodiment;

[0048] Specifically, the driving component 7 includes sliders 704 symmetrically fixedly connected to both sides of the limiting plate 4. The inner walls of both sides of the limiting groove 201 are symmetrically provided with sliding grooves 702. The sliders 704 are inserted into the inside of the sliding grooves 702. A threaded rod 703 is threadedly connected to the middle of one slider 704. A second torsion cap 706 is fixedly connected to one end of the threaded rod 703. A limiting ring 705 is sleeved in the middle of the threaded rod 703. A limiting rod 701 is inserted into the middle of the other slider 704. The limiting rod 701 is used to limit the shaking of the limiting plate 4.

[0049] It should be noted that the slider 704 is adapted to the groove 702, allowing the slider 704 to slide inside the groove 702; the second torsion cap 706 and the limiting ring 705 are both fixedly connected to the threaded rod 703, with the second torsion cap 706 fitting against the front of the fixing block 2 and the limiting ring 705 fitting against the inner wall of the front of one of the grooves 702. The second torsion cap 706 and the limiting ring 705 restrict the position of the threaded rod 703, preventing it from moving and ensuring that the threaded rod 703 can move freely. 03 can rotate; the limiting rod 701 is fixedly connected inside another slide groove 702, and the limiting rod 701 is set parallel to the threaded rod 703. The movement direction of the limiting plate 4 and the slider 704 is limited by the two fixed rods; when it is necessary to move the position of one of the sliders 704, the threaded rod 703 is rotated by the second torsion cap 706, and the rotating threaded rod 703 drives the slider 704, which is threaded to it and cannot rotate, to move, and the moving slider 704 drives the limiting plate 4 to move.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
