Description

Technical Field

[0001] This application relates to the field of optical component processing technology, specifically to a tension spring locking device for fixing a long strip prism. Background Technology

[0002] Chamfering and beveling in optical component manufacturing is a seemingly simple but crucial process that directly impacts the safety, reliability, and overall performance of optical components. Optical glass and crystal materials are typically hard and brittle. During processing, handling, assembly, or use, sharp edges are highly susceptible to impacts and breakage, resulting in micro-chipping. These chips can become the origin of cracks, leading to complete breakage of the component during subsequent processing (such as coating or bonding) or under stress. At sharp edges, stress is highly concentrated, and these stress concentration points can easily lead to crack formation when the component is subjected to external forces (such as clamping force or thermal expansion and contraction). Smooth chamfers or rounded corners can effectively disperse these stresses, improving the component's mechanical strength and thermal shock resistance. Furthermore, components with smooth chamfers or rounded corners are easier to place into lens mounts or lens barrels, preventing burrs or sharp edges from jamming or scratching precision mechanical parts. This significantly improves assembly efficiency and yield.

[0003] Existing edge beveling methods typically employ manual beveling, where operators use specialized grinding stones or polishing tools (such as grinders) to polish the edges of components based on experience and feel. However, this method is not only inefficient but also highly dependent on the operator's skills, easily resulting in defective products (e.g., inconsistent polishing curvature at different points along the same edge). Utility Model Content

[0009] In this embodiment of the application, the fixing component includes: two fixing brackets, which are respectively fixedly connected to two support frames, and the fixing brackets are adapted to the grinding machine worktable and snap-fitted to the grinding machine worktable; and two connecting blocks, which are respectively fixedly connected to the two fixing brackets, and the two connecting blocks abut against the support plates of the two support frames, with the abutting side being the side of the support plate facing away from the first and second horizontal plates.

[0010] In this embodiment, the height adjustment mechanism includes: two L-shaped fixing plates, each connected to two wedges; each L-shaped fixing plate includes a horizontal connecting plate and a vertical connecting plate connected to each other, the horizontal connecting plate being fixedly connected to the wedges; and two support frames, each support frame including a vertically arranged support plate, a first horizontal plate connected to the top of the support plate, and a second horizontal plate connected to the bottom of the support plate, the first horizontal plate and the second horizontal plate being parallel and located on the same side of the support plate, and the first horizontal plate and the second horizontal plate being fixedly connected.

Example

[0022] like Figure 1 As shown, this embodiment provides a chamfering fixture based on a grinding machine. The grinding machine's worktable 200 is equipped with a grinding disc 300. The chamfering fixture includes: Two beveled wedges 1 are positioned close together and aligned to form a V-shaped groove for accommodating the target glass piece 100. Preferably, the two wedges 1 are the same size and shape (the slopes of their bevels are the same), forming a symmetrical V-shaped groove structure. The opening of the V-shaped groove faces upwards horizontally, facilitating the placement of the target glass piece 100 (without needing to consider which side of the target glass piece 100 it abuts against), ensuring the accuracy of the beveling radius of the target glass piece 100's edges. A gap of a preset width exists at the bottom of the V-shaped groove, through which the edge of the target glass piece 100 can pass. The gap is located at the lowest point of the two wedges 1, and the V-shaped groove is located above the grinding disc 300; that is, the edge of the target glass piece 100 passing through the gap is at its lowest point, ensuring that the grinding disc 300 can grind the edge without causing wear to the wedges 1. The plane containing the gap is parallel to the surface of the grinding disc 300, which ensures that there is no angle between the gap and the horizontal direction, and ensures that the degree of grinding and the beveling curvature are consistent at all points on the edge during the grinding process.

[0023] An adjustment component, connected to the wedge 1, is used to adjust the width of the gap and the height of the V-groove; that is, the adjustment component mainly comprises two parts: a width adjustment mechanism and a height adjustment mechanism. This embodiment provides two types of width and height adjustment mechanisms with different structures and positional relationships (detailed in embodiments 2 and 3): 1) Width adjustment mechanism, which is connected to the wedge block 1 and is used to adjust the width of the gap; Height adjustment mechanism, which is connected to the width adjustment mechanism and the fixing component respectively and is used to adjust the height of the V-groove; 2) Height adjustment mechanism, which is connected to wedge 1 and is used to adjust the height of the V-groove; Width adjustment mechanism, which is fixedly connected to the height adjustment mechanism and slidably connected to the fixed component, and is used to adjust the width of the gap.

[0024] A fixing component is included, which is adapted to the worktable 200 of the grinding machine. The fixing component connects to both the adjusting component and the worktable 200, and is used to fix the wedge 1. The fixing component firmly secures the adjusting component to the worktable 200, facilitating the adjustment and fixing of the two wedges 1 and providing favorable support for the adjusting component. Furthermore, the connection between the fixing component and the worktable 200 will not damage the worktable 200, avoiding any impact on the subsequent use and aesthetic appearance of the grinding machine. Based on the above two structures and positional relationships of the width and height adjustment mechanisms, the structure of the fixing component has been adapted in the following embodiments to accommodate these two structures and positional relationships; please refer to embodiments 2 and 3 for details. Example

[0025] In this embodiment, the adjustment component includes: a width adjustment mechanism connected to the wedge block 1, which is used to adjust the width of the gap; and a height adjustment mechanism connected to both the width adjustment mechanism and the fixing component, which is used to adjust the height of the V-groove.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the width adjustment mechanism includes: Two L-shaped fixing plates 2 are respectively connected to two wedges 1; the L-shaped fixing plates 2 include interconnected horizontal connecting plates and vertical connecting plates, the horizontal connecting plates are connected along the horizontal direction (e.g., Figure 1 As shown (in the movable direction of wedge 1 on the horizontal plane), there are rows of holes 21 for connecting wedge 1. By connecting wedge 1 to different holes, the distance (width of the gap) between two wedge 1s can be adjusted, thereby adjusting the curvature of the chamfered edge. The vertical connecting plate is connected to the height adjustment mechanism to realize height adjustment.

[0027] Specifically, the height adjustment mechanism includes: Two support frames 3 are provided. Each support frame 3 includes a vertically arranged support plate, a first horizontal plate connected to the top of the support plate, and a second horizontal plate connected to the bottom of the support plate. The first horizontal plate and the second horizontal plate are parallel and located on the same side of the support plate. A fixing rod 4 is fixedly connected between the first horizontal plate and the second horizontal plate. Preferably, the support plate, the first horizontal plate, and the second horizontal plate are integrally connected, which can improve the overall stability and reliability of the support frame 3.

[0028] Two movable blocks 5 are connected to two support frames 3 respectively. The movable blocks 5 are sleeved on the fixed rod 4 and are slidably connected to the fixed rod 4. The two movable blocks 5 are connected to two L-shaped fixed plates 2 respectively. One side of the movable block 5 is fixedly connected to the back plate side of the vertical connecting plate. The back plate side of the vertical connecting plate is the side of the vertical connecting plate facing away from the horizontal connecting plate.

[0029] Two screws 6 are threadedly connected to two movable blocks 5 respectively; one end of each screw 6 passes through the first horizontal plate and the movable block 5 and is rotatably connected to the second horizontal plate, as shown below. Figure 2 As shown.

[0030] When adjusting the height, the movable block 5 can be raised or lowered by applying a clockwise or counterclockwise rotational force (e.g., by hand) to the other end of the screw 6 pre-installed on the first horizontal plate. The movable block 5 then drives the L-shaped fixed plate 2 and the wedge block 1 to rise or fall. In addition, since a fixed rod 4 is also installed inside the movable block 5 when the screw 6 is rotated, and the two ends of the fixed rod 4 are fixedly connected to the first horizontal plate and the second horizontal plate respectively, the movable block 5 will not rotate with the screw 6 when the screw 6 is rotated, but will move up and down along the screw 6 and the fixed rod 4.

[0031] Specifically, the fixing component includes: Two fixed brackets 7 are fixedly connected to two support frames 3 respectively. The fixed brackets 7 are adapted to the grinding machine worktable 200 and are fixedly connected to the grinding machine worktable 200 by snap-fit. Two connecting blocks 8 are fixedly connected to two fixed brackets 7, and each connecting block 8 abuts against the support plates of the two support frames 3. The abutting side is the side of the support plate facing away from the first and second horizontal plates. This improves the stability of the support frame 3 and prevents the support rod from wobbling when adjusting the position and height of the movable block 5 by rotating the screw 6. Additionally, features such as... can be provided on the connecting blocks 8. Figure 1 The handle 81 shown is for easy handling of the entire tooling.

[0032] Furthermore, the fixed bracket 7 includes: two pads 71, which are respectively fixedly connected to two connecting blocks 8 and two support frames 3; and a workbench fastener 72, which is used to fix the pads 71 ​​and the grinding machine workbench 200. For example, the workbench fastener 72 can be adopted as follows: Figure 3 The U-shaped snap-fit ​​connector shown is inserted from the edge of the worktable 200 of the grinding machine, and the worktable 200 and the pad 71 are locked in the U-shaped opening. The part of the U-shaped snap-fit ​​connector located below the worktable has a threaded hole. Through the thread, the screw is tightened so that the free end of the screw is tightly abutted against the bottom wall of the worktable, ensuring that the part of the U-shaped snap-fit ​​connector located above the worktable is pressed against the pad 71.

[0033] Preferably, the fixing component further includes a connecting bracket 9, which is used to connect the two connecting blocks 8 into a whole so that the two wedge blocks 1 are always in the same vertical plane, avoiding misalignment and improving the alignment efficiency of the two inclined surfaces that form the V-groove.

[0034] The specific process of beveling using the beveling fixture provided in this embodiment is as follows: Determine the desired beveling radius of the target glass part 100; determine the desired gap width and desired beveling time based on the desired beveling radius; estimate the portion of the target glass part 100 exposed outside the gap based on the desired gap width (the size of the target glass part 100 is known), i.e., determine the height difference between the part of the target glass part 100 to be ground and the gap; determine the desired height of the wedge 1 based on this height difference and the position of the grinding disc 300; adjust the two wedges 1 to the desired height using the height adjustment mechanism, and then adjust the gap at the bottom of the V-groove to the desired width using the width adjustment mechanism; finally, place the target glass part 100 into the V-groove with the edge to be ground facing downwards, naturally protruding from the V-groove. To prevent the target glass part 100 from shifting when the grinding disc 300 grinds it, the target glass part 100 can be fixed using other tools or manually before grinding begins. Example

[0035] In this embodiment, the adjustment component includes: a height adjustment mechanism connected to the wedge block 1, the height adjustment mechanism being used to adjust the height of the V-groove; and a width adjustment mechanism fixedly connected to the height adjustment mechanism and slidably connected to the fixing component, the width adjustment mechanism being used to adjust the width of the gap.

[0036] Specifically, such as Figure 3 As shown, the height adjustment mechanism includes: Two L-shaped fixing plates 2 are connected to two wedges 1 respectively. In this embodiment, the two L-shaped fixing plates 2 are transition pieces. Since the wedges 1 need to be able to move horizontally to adjust the width of the gap and also need to be able to move vertically to adjust the height, L-shaped fixing plates 2 are introduced. The L-shaped fixing plates 2 include horizontal connecting plates and vertical connecting plates that are connected to each other. The horizontal connecting plates of the L-shaped fixing plates 2 are fixedly connected to the wedges 1, and the vertical connecting plates are connected to the movable blocks 5 that can move up and down.

[0037] Two support frames 3 are provided. Each support frame 3 includes a vertically arranged support plate, a first horizontal plate connected to the top of the support plate, and a second horizontal plate connected to the bottom of the support plate. The first horizontal plate and the second horizontal plate are parallel and located on the same side of the support plate. A fixing rod 4 is fixedly connected between the first horizontal plate and the second horizontal plate. Preferably, the support plate, the first horizontal plate, and the second horizontal plate are integrally connected, which can improve the overall stability and reliability of the support frame 3.

[0038] Two movable blocks 5 are connected to two support frames 3 respectively. The movable blocks 5 are sleeved on the fixed rod 4 and are slidably connected to the fixed rod 4. The two movable blocks 5 are connected to two L-shaped fixed plates 2 respectively. One side of the movable block 5 is fixedly connected to the back plate side of the vertical connecting plate. The back plate side of the vertical connecting plate is the side of the vertical connecting plate facing away from the horizontal connecting plate.

[0039] Two screws 6 are threadedly connected to two movable blocks 5 respectively; one end of each screw 6 passes through the first horizontal plate and the movable block 5 and is rotatably connected to the second horizontal plate.

[0040] The height adjustment method can be referred to in Example 2, and will not be repeated here.

[0041] Specifically, the width adjustment mechanism includes: Two connecting blocks 8 are fixedly connected to the support plates of the two support frames 3 respectively, and their connecting side is the side of the support plate facing away from the first horizontal plate and the second horizontal plate; the connecting blocks 8 are slidably connected or fixedly connected to the fixing components (with the help of other locking parts). When slidably connected, the two connecting blocks 8 can respectively drive the two wedges 1 to move closer to each other or further away from each other within a predetermined range.

[0042] The fixing components include: two pads 71, which are slidably or fixedly connected to two connecting blocks 8 respectively, and each of the pads 71 ​​is provided with a slide 711 adapted to the connecting block 8; and a workbench fastener 72, which is used to fix the connecting pads 71 ​​and the grinding machine workbench 200.

[0043] The width adjustment mechanism provided in this embodiment has the advantage over the solution in Embodiment 2 in that it eliminates the need for frequent replacement of the connecting holes, making gap width adjustment more convenient. The fixing between the connecting block 8 and the pad 71 can be achieved using other locking components, such as lead screws or limit blocks; specific examples can be found in existing sliding limit structures.

[0044] Furthermore, in this embodiment, the fixing component further includes a connecting bracket 9. Unlike the connecting block 8 in Embodiment 2, the connecting block 8 in this embodiment, as a width adjustment mechanism, needs to move the wedge block 1. Therefore, the connecting bracket 9 in this embodiment connects two fixing seats 7 into a whole, ensuring that the two wedge blocks 1 are always in the same vertical plane, preventing misalignment and improving the alignment efficiency of the inclined surfaces of the two wedge blocks 1. In Embodiment 2, directly connecting the two connecting blocks 8 provides reinforcement, and the connecting bracket 9 is at a certain height from the grinding machine worktable 200, making it easy to pick up and move, which helps improve the overall stability of the workpiece.
