Description

Technical Field

[0001] This utility model relates to the field of prism processing tools, and in particular to an adjustable-angle rhomboid prism chamfering auxiliary tool. Background Technology

[0002] Rhomboid prisms are precision optical instruments, and the chamfering tool for prisms is mainly used in the field of optical instrument manufacturing. In the production of high-precision optical prisms, it can precisely chamfer the edges of the prism according to the design angle requirements of different prisms, ensuring the optical performance and appearance quality of the prism, and improving production efficiency and product quality.

[0003] Traditional beveling tools can fix prisms at a specific angle for easy beveling. However, they can only handle prisms at fixed angles and cannot flexibly adapt to the design requirements of different prisms, resulting in poor versatility. Furthermore, traditional tools are complex to operate, requiring professional personnel for adjustment and operation, increasing labor costs and operational difficulty. Moreover, the beveling precision is not high enough, easily resulting in uneven edges, affecting the optical performance of the prism and failing to meet the precision and surface finish requirements of optical glass processing.

[0004] Therefore, a new adjustable-angle rhombic prism beveling tool is proposed, which features low cost, simple operation, and strong applicability. Utility Model Content

[0044] Please see Figure 1 and Figure 2 The diagram illustrates an embodiment of an adjustable-angle rhomboid prism beveling aid, comprising a base 1 with multiple parallel mounting slots 11 on its surface, and mounting brackets 2 connected to both ends of the mounting slots 11 along their length; angle adjustment devices 5, the same number as the mounting slots 11, each end of which is mounted in the mounting slot 11 via a pair of bearing supports 6; and angle adjustment rods connected to the mounting brackets 2 for adjusting the angle of the angle adjustment devices 5; wherein the angle adjustment rods include a first angle adjustment rod 3 for adjusting the rotation angle of the angle adjustment devices 5 (e.g., ...). Figure 6 (as shown); and a second angle adjustment rod 4, used to adjust the opening and closing angle of the angle adjustment device 5 (as shown). Figure 6 (As shown).

[0045] In this embodiment, the chassis base 1 has four parallel mounting slots 11, and the angle adjustment device 5 has four slots, which are respectively installed in the mounting slots 11.

[0046] In this embodiment, the first angle adjustment rod 3 is installed in the mounting bracket 2 on one side of the chassis base 1, and the second angle adjustment rod 4 is installed in the mounting bracket 2 on the other side of the chassis base 1. Both the first angle adjustment rod 3 and the second angle adjustment rod 4 are connected to the angle adjustment device 5 through a gear meshing structure, so as to control the opening angle and rotation angle of the angle adjustment device 5 through the gear meshing structure.

[0047] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the angle adjustment device 5 includes a rotating cylinder 51, which includes a cylindrical cylinder 511 and two end caps 512 respectively connected to both ends of the cylindrical cylinder 511. A rotating angle gear 513 is provided on the outside of one end cap 512; a rotating shaft 52 is rotatably connected to both end caps 512; a first clamping plate 53 is fixed to the rotating cylinder 51; and a second clamping plate 54 is rotatably connected at both ends to the two end caps 512 through half gear shafts 541. The half gear shafts 541 are connected to the rotating shaft 52. The rotation of the rotating shaft 52 drives the second clamping plate 54 to rotate around the axis of the half gear shaft 541 and move closer to or away from the first clamping plate 53, so as to form a state in which the V-shaped opening angle between the first clamping plate 53 and the second clamping plate 54 increases or decreases.

[0048] In this embodiment, the rotating shaft 52 includes a rotating rod 521 connected between two end caps 512, with one end submerged in the end cap 512 located on one side of the rotating angle gear 513, and the other end protruding outside the other end cap 512; an opening and closing angle gear 522 connected to the protruding end of the rotating rod 521; and a rotating gear 523 formed on the rotating rod 521, the number of which is the same as that of the half gear shaft 541, and the rotating gear 523 meshes with the tooth surface of the half gear shaft 541.

[0049] In this embodiment, see continue to refer to Figure 1 and Figure 2 As shown, the first angle adjusting rod 3 is provided with a number of first bevel gears 31 that are the same as the number of rotation angle gears 513. The first bevel gears 31 mesh with the rotation angle gears 513 to control the rotation angle of the angle adjusting device 5.

[0050] In this embodiment, the second angle adjusting rod 4 is provided with a number of second bevel gears 41 that are the same as the opening and closing angle gears 522. The second bevel gears 41 mesh with the opening and closing angle gears 522. By rotating the second angle adjusting rod 4, the rotating shaft 52 is driven to rotate to control the opening and closing angle between the second clamping plate 54 and the first clamping plate 53.

[0051] In this embodiment, the first angle adjustment rod 3 and the second angle adjustment rod 4 are damped and mounted on the mounting bracket 2. The damping coefficient is sufficient to ensure that the angle adjustment device 5 will not change due to vibration when the auxiliary tool works with external equipment, so as to ensure that the angle adjustment device 5 is firmly clamped to the prism and that the rotation angle and opening angle of the angle adjustment device 5 will not change.

[0052] In this embodiment, as Figure 8 As shown, there is a damped connection between the end cap 512 and the bearing support 6, and further, there is a damped connection between the bearing 61 and the bearing support 6, to ensure that the end cap 512 and the bearing support 6 will not rotate relative to each other when not driven by the first angle adjustment rod 3, thus preventing changes in the rotation angle of the angle adjustment device 5.

[0053] In this embodiment, as Figure 7 As shown, both the first clamping plate 53 and the second clamping plate 54 have an adhesive layer 55 on their opposing surfaces. No other structures are used to contact and position the prism. This is because: firstly, interference will occur during chamfering; secondly, it ensures that no other structure contacts the prism, preventing edge chipping; and thirdly, the contact surface of the prism is smooth, and the specific adhesive layer is sufficient to clamp it through static friction, ensuring a firm grip of the prism by the angle adjustment device 5. The adhesive layer 55 is preferably made of, for example, medical / optical grade platinum-catalyzed solid silicone sheet, which has adhesive strength and will not leave marks on the prism surface after chamfering.

[0054] The following description will further illustrate the characteristics and functions of this utility model.

[0055] The method for using the auxiliary tool in this embodiment is as follows:

[0056] First, place the prism between the first clamping plate 53 and the second clamping plate 54. Then, rotate the second angle adjusting rod 4, causing the rotating shaft 52 to rotate. This, through the rotating gear 523, moves the second clamping plate 54 closer to the first clamping plate 53 until the adhesive layer 55 of the two plates firmly clamps the surface of the prism. The relative angle between the first and second clamping plates will be different for different sizes and models of prisms, thus allowing for the use of different types of prisms.

[0057] Then, once the prism is fixed, rotate the first angle adjustment rod 3. This will cause the rotating cylinder 51 to rotate as a whole through the rotating angle gear 513, while simultaneously rotating the first clamping plate and the second clamping plate, which have already been shaped and are holding the prism, to rotate together to the specified angle. In other words, the prism can be chamfered at the desired position and angle by controlling the first angle adjustment rod 3 to adjust the prism in the rotating cylinder 51 to the corresponding angle.

[0058] Preferably, the top edge of the mounting groove 11 may be provided with a chamfer 12 to accommodate the angle adjustment of the angle adjustment device 5.

[0059] In summary, the auxiliary tool of this invention, through an angle adjustment device that can control the opening and closing angles and rotation angles, can adapt to the beveling requirements of prisms of different sizes, shapes, and beveling specifications, demonstrating wide versatility. Furthermore, the auxiliary tool has a simple structure, is easy to operate, and requires no additional professional personnel, significantly saving labor costs. Simultaneously, when fixing different types of prisms, the specific angle and position of the prism can be controlled by a combination of the first and second angle adjustment rods according to the beveling requirements, achieving beveling at specific angular positions on the prism and ensuring high-precision beveling.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
