Description

Technical Field

[0001] This utility model relates to the field of optical product processing equipment technology, and in particular to a positioning fixture for assembling rhomboid prisms. Background Technology

[0002] In the field of optical component manufacturing and assembly, rhombic prisms are an important optical device. During assembly, they often require positioning fixtures for positioning. The accuracy and stability of positioning directly affect the optical performance and overall quality of the rhombic prism.

[0003] Currently, the traditional positioning fixtures for rhombic prism assembly are relatively simple in design and difficult to adapt to the positioning requirements of rhombic prisms of different specifications. When it is necessary to position rhombic prisms of different specifications, it is often necessary to make complex adjustments or replacements to the entire positioning fixture, which is cumbersome and seriously affects the actual assembly efficiency. Therefore, in order to solve this problem, it is necessary to design a positioning fixture for rhombic prism assembly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for assembling rhomboid prisms. Addressing usability issues, it incorporates a positioning mechanism that, by controlling the opposite movement of two positioning blocks, facilitates the positioning of the rhomboid prism body, reducing the workload. Furthermore, in conjunction with a limiting component, the positioning blocks can be easily replaced to accommodate positioning of rhomboid prism bodies of different specifications, demonstrating good practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning fixture for assembling a rhombic prism includes a base with a U-shaped fixing frame fixedly connected to its upper end; a positioning mechanism comprising a bidirectional threaded rod rotatably connected between the inner walls of the left and right sides of the U-shaped fixing frame, with sliders threaded to both threaded ends of the bidirectional threaded rod; a T-shaped inner groove formed at the upper end of each slider; a positioning block provided on the opposing sides of each slider; a positioning groove formed on the opposing sides of each positioning block; a rhombic prism body fitted between the two positioning grooves; and a T-shaped protrusion fixedly connected to the opposite sides of each positioning block, with each T-shaped protrusion slidably connected to the inner wall of its corresponding T-shaped inner groove; and two limiting components, each used to limit the corresponding T-shaped protrusion.

[0007] Preferably, rubber pads are provided in both positioning slots, and the right end of the bidirectional threaded rod penetrates the right inner wall of the U-shaped fixing frame and is fixedly connected to a circular rotating block.

[0008] Preferably, a guide rod is fixedly connected between the inner walls of the left and right sides of the U-shaped fixing frame, and the guide rod passes through the two sliders and is slidably connected to the two sliders.

[0009] Preferably, the limiting component includes a control block disposed on the side wall of the slider, a limiting block is fixedly connected to the side wall of the control block, and a spiral permanent magnet is fixedly connected to the side wall of the control block.

[0010] Preferably, the opposing ends of the two limiting blocks both penetrate the slider and extend into the T-shaped inner groove.

[0011] Preferably, the lower ends of both limiting blocks are in contact with the upper ends of the corresponding T-shaped protrusions.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] A positioning mechanism is provided, which drives the bidirectional threaded rod to rotate by rotating the circular rotating block, causing the two positioning blocks to move towards each other. With the help of rubber pads, stable and accurate positioning of the rhomboid prism body can be easily achieved. The overall operation is convenient and effectively reduces the actual positioning workload. At the same time, with the help of two limiting components, two T-shaped protrusions and two T-shaped inner grooves, the positioning blocks can be easily replaced by plugging and unplugging the limiting blocks, thus effectively meeting the positioning needs of rhomboid prism bodies of different specifications, and greatly improving the practicality and versatility of the positioning fixture.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A positioning fixture for assembling a rhombic prism includes a base 1, with a U-shaped fixing frame 2 fixedly connected to the upper end of the base 1.

[0021] The system also includes a positioning mechanism, comprising a bidirectional threaded rod 3 rotatably connected between the inner walls of the left and right sides of the U-shaped fixing frame 2. The two threaded ends of the bidirectional threaded rod 3 have opposite thread directions. The right end of the bidirectional threaded rod 3 penetrates the inner wall of the right side of the U-shaped fixing frame 2 and is fixedly connected to a circular rotating block 11. Both threaded ends of the bidirectional threaded rod 3 are threadedly connected to sliders 4. A guide rod 12 is fixedly connected between the inner walls of the left and right sides of the U-shaped fixing frame 2. The guide rod 12 penetrates two sliders 4 and is slidably connected to the two sliders 4. The upper end of each slider 4 is provided with a T-shaped inner groove 5. A positioning block 6 is provided on the opposite side of each slider 4. The opposite side of each positioning block 6 is provided with a... The positioning groove 7 has a rhomboid prism body 8 fitted between the two positioning grooves 7. By rotating the circular rotating block 11, the bidirectional threaded rod 3 is rotated, which drives the two sliders 4 and the two positioning blocks 6 to move towards each other until the two positioning grooves 7 are fitted with the left and right ends of the rhomboid prism body 8, thus achieving convenient positioning of the rhomboid prism body 8. Rubber pads 10 are provided in both positioning grooves 7. The rubber pads 10 can improve the stability of positioning the rhomboid prism body 8 and ensure that the rhomboid prism body 8 is not excessively squeezed and damaged. T-shaped protrusions 9 are fixedly connected to the opposite sides of the two positioning blocks 6. The two T-shaped protrusions 9 are slidably connected to the inner wall of the corresponding T-shaped inner groove 5.

[0022] The system also includes two limiting components, each used to limit the corresponding T-shaped protrusion 9. Each limiting component includes a control block 13 mounted on the side wall of the slider 4. A limiting block 14 is fixedly connected to the side wall of the control block 13. A circular permanent magnet 15 is fixedly connected to the side wall of the control block 13. The part of the slider 4 that is in contact with the circular permanent magnet 15 is made of iron. The magnetic attraction between the circular permanent magnet 15 and the slider 4 ensures the stability of the control block 13 and the limiting block 14, thereby ensuring the stable limiting of the T-shaped protrusion 9 by the limiting block 14. The opposing ends of the two limiting blocks 14 penetrate the slider 4 and extend into the T-shaped inner groove 5. The lower ends of the two limiting blocks 14 are in contact with the upper ends of the corresponding T-shaped protrusion 9.

[0023] In this invention, during use, firstly, according to the dimensions of the rhombic prism body 8 to be assembled, the circular rotating block 11 is rotated to drive the bidirectional threaded rod 3 to rotate, causing the two sliders 4 to move towards each other along the guide rod 12, and causing the two positioning blocks 6 to move towards each other until the distance between the two positioning blocks 6 is close to the dimensions of the rhombic prism body 8. Then, the rhombic prism body 8 is placed between the two positioning blocks 6, so that the left and right ends of the rhombic prism body 8 are respectively placed in the corresponding positioning grooves 7. Then, the circular rotating block 11 is rotated again to drive the two positioning blocks 6 to move towards each other until the left and right ends of the rhombic prism body 8 are respectively in contact with the rubber pads 10 in the corresponding positioning grooves 7. In this way, the precise positioning of the rhombic prism body 8 can be achieved (e.g., Figure 1 As shown in the image, the entire positioning process is quite convenient;

[0024] When it is necessary to replace the positioning block 6 with a different specification to accommodate the rhombic prism body 8 of a different specification, first replace the positioning block 6 on the right side. Pull the control block 13 on the right side to remove the corresponding limiting block 14 and the circular permanent magnet 15 to release the limiting of the T-shaped protrusion 9. Then move the positioning block 6 upward so that the T-shaped protrusion 9 is completely removed from the T-shaped inner groove 5. The positioning block 6 can then be removed. Then replace it with a new positioning block 6 (the positioning groove 7 on this positioning block 6 can fit the end part of the rhombic prism body 8 to be positioned). Remove the T-shaped protrusion on the positioning block 6. 9 slides into the T-shaped inner groove 5 on the right, and then the limiting block 14 re-penetrates the slider 4 and extends into the T-shaped inner groove 5, so that the lower end of the limiting block 14 fits against the upper end of the T-shaped protrusion 9. At the same time, the magnetic attraction between the circular permanent magnet 15 and the slider 4 ensures the stability of the limiting block 14. In this way, the new positioning block 6 can be stably positioned. Similarly, referring to the above operation, the positioning block 6 on the left can be replaced. The whole replacement operation is relatively convenient. By replacing the positioning block 6, the stable positioning of the rhomboid prism body 8 of different specifications can be achieved, which has good practicality.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
