Description

Technical Field

[0001] This disclosure generally relates to the field of optical component processing technology, and specifically to chamfering fixtures and chamfering methods applicable to boss optical components. Background Technology

[0002] The design of the chamfer on the boss optical component requires specific chamfer angles and widths for the boss edges.

[0003] In existing processing technologies, optical components are typically chamfered manually on a chamfering machine or using conventional tooling. This often leads to problems such as uneven force application, difficulty in holding the component, excessive angle and width deviations due to wear of conventional tooling, and high operator fatigue, resulting in low chamfering accuracy, poor consistency, and low product yield. Therefore, we propose a chamfering tooling and method suitable for boss-shaped optical components to solve these problems. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a chamfering fixture and chamfering method that is simple in structure and highly practical for use with boss optical parts.

[0005] In a first aspect, this application provides a chamfering fixture suitable for boss optical components, the chamfering fixture comprising:

[0006] According to the technical solution provided in the embodiments of this application, the chamfering fixture body is a triangular prism structure;

[0007] The chamfering fixture body has a triangular bottom surface and a triangular top surface, and the edges between the bottom surface and the top surface are all perpendicular to the triangle of the bottom surface and the top surface, forming three corresponding prism sides.

[0008] The chamfering fixture body includes: a first fixing part, which is provided on the prism side of the chamfering fixture body; the first fixing part is used to fix the protrusion of the boss part that needs to be chamfered, so that the edge of the protrusion can contact the grinding machine to perform the chamfering operation.

[0009] According to the technical solution provided in the embodiments of this application, the inner angles of the triangles on the bottom and top surfaces of the chamfering fixture body are 30°, 45°, and 105°, respectively; the first fixing part is provided on the two prism sides corresponding to the inner angles of 30° and 45°.

[0010] According to the technical solution provided in the embodiments of this application, the first fixing part is a first groove guide rail formed on the chamfered tooling body;

[0011] The first groove guide rail has a first threaded positioning hole on its inner side.

[0012] According to the technical solution provided in the embodiments of this application, the chamfering fixture further includes:

[0013] An adjustable inner liner strip, wherein the adjustable inner liner strip has a second threaded positioning hole corresponding to the first threaded positioning hole;

[0014] Along the second direction, the cross-sectional length of the adjustable inner liner is less than the length between the two inner edges of the first groove guide rail.

[0015] According to the technical solution provided in the embodiments of this application, the chamfering fixture further includes:

[0016] The compensator is a triangular prism structure used to combine with the chamfering fixture body to form chamfered surfaces at different angles.

[0017] According to the technical solution provided in the embodiments of this application, the compensator also has a triangular bottom surface and a triangular top surface, and the edges between the bottom surface and the top surface are all perpendicular to the triangle of the bottom surface and the top surface;

[0018] The triangle has an interior angle of 15° on both the base and top surfaces. A second fixing part is provided on the prism side corresponding to the interior angle of 15°. A second groove guide rail is provided on the second fixing part. A third threaded positioning hole is provided on the inner side of the second groove guide rail.

[0019] Secondly, this application provides a chamfering method, which is applied to the chamfering fixtures used for the aforementioned boss optical parts;

[0020] The chamfering method includes the following steps:

[0021] Select the target chamfered surface on the chamfering fixture body according to the chamfering angle process requirements;

[0022] Adjust the position of the adjustable inner liner in the first groove guide or the second groove guide according to the size of the protrusion in the boss part, so that the boss part can slide in the corresponding groove guide;

[0023] The prism side corresponding to the inner angle of 105° in the chamfering fixture body is placed on a grinding machine, which includes a diamond grinding disc driven by a single-axis machine.

[0024] Start the grinding machine and place the boss part into the first groove guide rail or the second groove guide rail in the target angle inclined plane, so that the edge of the boss part can contact the sanding disc in operation.

[0025] According to the chamfering angle process requirements, the edges of the protrusions are chamfered sequentially.

[0026] According to the technical solution provided in the embodiments of this application, after performing chamfering operations on the edges of the boss part in sequence according to the chamfering angle process requirements, the process includes:

[0027] When it is determined that the current chamfer dimension of the boss part does not meet the chamfer angle process requirements,

[0028] Repeat the step of placing the boss part into the first groove guide or the second groove guide in the prism side corresponding to the target chamfered bevel, so that the edge of the boss part can contact the sand disc in operation, until the chamfer size of each edge of the boss part is reached.

[0029] In summary, this technical solution specifically discloses a chamfering fixture suitable for boss optical components. The chamfering fixture body comprises a triangular prism structure, having a triangular base and top surface, with the edges between the base and top surface perpendicular to the triangle, forming three corresponding prism sides. The chamfering fixture body includes a first fixing part, which is located on the prism side of the chamfering fixture body. The first fixing part is used to fix the protrusion of the boss component to be chamfered, allowing the edges of the protrusion to contact a grinding machine for chamfering.

[0030] In existing technologies, the chamfering of optical components by hand on a chamfering machine or using conventional tooling often results in uneven force application and difficulty in holding the component. This application presents a chamfering tooling that effectively solves these problems. By using a first fixing part to fix the boss component to be chamfered, the cumbersome process of manually holding the component and chamfering it directly on the sander, which requires controlling both the component angle and the force, is eliminated. In this patent, the operator only needs to hold the boss component to be chamfered and the chamfering tooling body. Therefore, the problems of uneven force application and difficulty in holding the component are also solved. Attached Figure Description

Detailed Implementation

[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Example 1

[0040] Please refer to Figure 1 The schematic diagram shown in this embodiment illustrates the chamfering fixture body structure for a chamfering fixture suitable for boss optical components. The chamfering fixture includes:

[0041] The chamfering fixture body 100 is a triangular prism structure.

[0042] The chamfering fixture body 100 has a triangular bottom surface and a triangular top surface, and the edges between the bottom surface and the top surface are all perpendicular to the triangle of the bottom surface and the top surface, forming three corresponding prism sides.

[0043] The chamfering fixture body 100 includes: a first fixing part, which is provided on the prism side of the chamfering fixture body 100; the first fixing part is used to fix the protrusion of the boss part that needs to be chamfered, so that the edge of the protrusion can contact the grinding machine to perform the chamfering operation.

[0044] In this embodiment, the chamfering fixture body 100 is a regular triangular prism structure, and the material of the chamfering fixture body 100 can be aluminum, without any special limitation.

[0045] The first fixing part is provided on the two prism sides of the chamfering fixture body 100. These two prism sides are two sides that do not contact the chamfering machine during chamfering and are used to fix the boss parts that need to be chamfered.

[0046] Preferably, in this embodiment, the inner angles of the bottom and top surfaces of the triangle are 30°, 45°, and 105°, respectively; the first fixing part is provided on the two inclined surfaces corresponding to the inner angles of 30° and 45°, and correspondingly, the prism side surface corresponding to the inner angle of 105° is a long inclined surface that needs to contact the chamfering machine. The contact between this long inclined surface and the grinding machine can also improve the stability of the chamfering fixture.

[0047] Specifically, the first fixing part is a first groove guide rail 200 formed on the chamfering tool body 100. The first groove guide rail 200, which is distributed on two inclined surfaces, is smoothly connected and is located in the middle of the two inclined surfaces.

[0048] like Figure 2 As shown, in order to improve the practicality of the chamfering tooling, this application provides a first threaded positioning hole 300 on the inner side of the first groove guide rail 200. The first threaded hole 300 cooperates with the adjustable inner liner 400 to adjust the width of the first groove guide rail 200 to accommodate parts with different widths of protrusions in boss parts.

[0049] Specifically, the adjustable inner liner 400 has a second threaded positioning hole 500 corresponding to the first threaded positioning hole 300. During use, the design of the first threaded hole 300 and the second threaded positioning hole 500 can accelerate the connection of the adjustable inner liner 400.

[0050] Along the second direction, the cross-sectional length of the adjustable inner liner 400 is less than the length between the two inner edges of the first groove guide rail 200, so that the adjustable inner liner 400 can be placed in the first groove guide rail 200.

[0051] like Figure 3 As shown, the chamfering fixture also includes:

[0052] The compensator 600 is a triangular prism structure used to combine with the chamfering fixture body 100 to form different chamfered surfaces.

[0053] The compensator 600 is a regular triangular prism structure with the same structure as the chamfering fixture body 100, but with different internal angles. Specifically, in this embodiment, the compensator 600 also has a triangular base and a triangular top, and the edges between the base and the top are all perpendicular to the triangles of the base and the top, forming the above-mentioned regular triangular prism structure.

[0054] The triangle has an interior angle of 15° on both its base and top surfaces. A second fixing part is provided on the prism side corresponding to the 15° interior angle. A second groove guide rail 700 is provided on the second fixing part. The second groove guide rail 700 has the same function as the first groove guide rail 200, which is also used to fix the boss part that needs to be chamfered. A third threaded positioning hole 800 is provided on the inner side of the second groove guide rail 700. The third threaded hole 800 is used to connect with a fourth threaded hole 900 provided on the chamfering fixture body 100.

[0055] It is important to note that, such as Figure 1 As shown, the first threaded hole 300 is not limited to being set in the grooved guide rail on one side; it can also be set on the other inclined surface. The side of the second grooved guide rail 700 of the compensator 600 can also be designed with a threaded hole, without any special limitation here. The selection of the various inner angles of the compensator 600 and the chamfering fixture body 100 is also not limited and can be designed according to the current processing requirements.

[0056] In summary, the design-specific chamfering of boss parts often has fixed angle and width requirements. Furthermore, due to the special shape of the parts, existing conventional chamfering methods involve hand-holding the parts on a chamfering machine, which is difficult to control, prone to bumps and knocks, and results in inconsistent angles and widths, low efficiency, fatigue, poor product consistency, and low product yield. This application designs a chamfering fixture to fix the boss parts that need chamfering. This fixture not only has a simple structure but also solves the problems of uneven force application, difficulty in holding the parts, and excessive angle and width deviations after wear of conventional fixtures, which are common in existing technologies where optical parts are chamfered manually on a chamfering machine or using conventional fixtures. The present invention provides precise angles and controllable widths when processing boss chamfers, effectively improving the processing efficiency and yield of boss parts. Furthermore, the present invention has wide applicability, adaptable to parts with different chamfering angles, width requirements, boss heights, and widths, with a simple fixture structure, easy operation, and strong practicality.

[0057] Example 2

[0058] like Figure 4 As shown, this embodiment provides a chamfering method, applied to the chamfering fixture for boss optical parts described in Example 1; specifically, the chamfering method includes the following steps:

[0059] S100: Select the target chamfer bevel on the chamfering fixture body 100 according to the chamfering angle process requirements;

[0060] At the same time, it is also necessary to choose whether to assemble the compensator 600 with the chamfering fixture body 100 according to the chamfering angle process requirements.

[0061] S200: Adjust the position of the adjustable inner liner 400 in the first groove guide rail 200 or the second groove guide rail 700 according to the size of the protrusion in the boss part, so that the boss part can slide in the corresponding groove guide rail; the setting of the adjustable inner liner 400 ensures the stable movement of the boss part.

[0062] S300: Place the prism side of the chamfering fixture body 100 corresponding to the inner angle of 105° on a grinding machine. The grinding machine includes a diamond grinding disc driven by a single-axis machine. In actual use, the diamond grinding disc is installed on the single-axis machine, ensuring that it rotates at a low speed and continuously adding water to keep the grinding disc moist.

[0063] S400: Start the grinding machine and place the boss part into the first groove guide rail 200 or the second groove guide rail 700 in the side of the prism corresponding to the target chamfered bevel, so that the edge of the boss part can contact the sanding disc in operation; specifically, when the boss part is in the position of the corresponding groove guide rail, the edge of the protrusion is just on the same plane as the long bevel and can contact the rotating sanding disc to start the chamfering operation.

[0064] S500: According to the chamfering angle process requirements, the edges of the protrusions are chamfered sequentially.

[0065] After performing chamfering operations on the edges of the protrusions according to the chamfering angle process requirements, the process includes:

[0066] When it is determined that the current chamfer dimension of the boss part does not meet the chamfer angle process requirements,

[0067] Repeat the step of placing the boss part into the first groove guide rail 200 or the second groove guide rail 700 in the prism side corresponding to the target chamfered bevel, so that the edge of the boss part can contact the sand disc in operation, until the chamfer size of each edge of the boss part is reached.

[0068] The above process is a process of removing the self-inspection chamfer width. If the chamfer angle does not meet the process requirements, repeat steps S400 and S500 until the chamfer size of each edge meets the standard.

[0069] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
