Description

Technical Field

[0001] This utility model belongs to the field of infrared optical lens processing technology, specifically relating to a protective fixture for preventing the falling of infrared optical lenses used in wire cutting processing. Background Technology

[0002] As a key component in optical systems, planar infrared optical lenses require high-precision dimensional machining. Traditional machining uses grinding wheels, but with technological advancements, wire EDM has become the mainstream method due to its high precision and efficiency. However, during wire EDM, when the cutting progress reaches approximately 50% or near completion, the lens is prone to sagging due to its own gravity, accompanied by vibration. This can lead to lens breakage or falling from the working position, resulting in scrapped parts and severely impacting production efficiency and yield. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a protective fixture for preventing the lens from falling during wire EDM processing of infrared optical lenses. The fixture effectively prevents the lens from sagging and vibrating during the cutting process by clamping and fixing it, thus ensuring processing stability.

[0004] This utility model discloses a protective fixture for preventing the fall of infrared optical lenses during wire cutting, which includes a fixed base, on which a first clamping block and a second clamping block are sequentially arranged. The first clamping block has a stud at the bottom that is threaded to the fixed base, and a steel wire is fixedly connected to the top, with the steel wire passing through the second clamping block; Both the first clamping block and the second clamping block have bolts radially connected to their sides to clamp the stud and the steel wire respectively.

[0005] A rubber layer is also provided on the opposite end faces of the first clamping block and the second clamping block.

[0006] The beneficial effects of this utility model are: Compared with existing technologies, when the online cutting process reaches a point where there is a risk of lens sagging (such as when the cutting progress reaches 50%), this utility model first clamps and fixes the fixed base to the worktable of the online cutting equipment. Then, the steel wire is passed through the gap after the lens is cut, and the first clamping block and the second clamping block are positioned at the upper and lower ends of the lens. The steel wire is pulled and tightened with bolts, so that the second clamping block initially clamps the lens and edge material. Finally, the first clamping block is rotated until it is tightly fitted and stably clamps the lens. This effectively prevents the lens from sagging and vibrating during the cutting process, ensuring processing stability. Attached Figure Description

[0007] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments are briefly introduced below.

[0008] Figure 1 This is a schematic diagram of the overall structure of the protective tooling in the embodiment.

[0009] Figure 2 This is a schematic diagram showing the usage status of the protective tooling in the embodiment.

[0010] In the attached diagram, the structural names represented by each number are as follows: 1-Fixed base, 2-First clamping block, 201-Rubber layer, 3-Second clamping block, 4-Stud, 5-Steel wire, 6-Bolt, 7-Lens. Detailed Implementation

[0011] 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.

[0012] Example 1 See Figures 1 to 2 As shown, a protective fixture for preventing the falling of infrared optical lenses during wire EDM processing is provided, including a fixed base 1, a first clamping block 2, a second clamping block 3, and a steel wire 5.

[0013] The fixed base 1 is clamped and fixed in a designated position by a fixture on the worktable of the wire cutting equipment. The bottom of the first clamping block 2 is threadedly connected to the fixed base 1 by a stud 4, allowing it to move up and down along the axial direction of the stud 4. A high-strength steel wire 5 is fixedly connected to the top of the first clamping block 2, and the steel wire 5 passes through the second clamping block 3.

[0014] Bolts 6 are radially arranged on the sides of the first clamping block 2 and the second clamping block 3 to respectively press the stud 4 and the steel wire 5 after they are adjusted to the correct position.

[0015] A rubber layer 201 is adhered to the opposite end faces of the first clamping block 2 and the second clamping block 3. The rubber layer 201 serves as the direct contact surface with the lens 7, preventing hard contact from damaging the lens surface.

[0016] Working principle: When the wire EDM process reaches a point where there is a risk of lens 7 sagging (e.g., the cutting progress reaches 50%), firstly, the fixed base 1 is clamped and fixed in a suitable position on the worktable. Then, the steel wire 5 connected to the first clamping block 2 is passed through the cutting gap of the lens 7, so that the second clamping block 3 is located on the other side of the lens 7. By pulling the steel wire 5 and using the bolts 6 on the second clamping block 3 to pre-tighten the steel wire 5, the second clamping block 3 is initially positioned. Then, the first clamping block 2 is rotated to move it axially along the stud 4 until the rubber layer 201 on the end face of the first and second clamping blocks 3 is fully in contact with the surface of the lens 7 and the edge material and a stable clamping force is applied. Finally, the bolts 6 on the first clamping block 2 and the second clamping block 3 are locked respectively to complete the entire clamping process.

[0017] For longer lenses 7, multiple fixtures can be installed at intervals along their processing path to form multi-point support and comprehensively prevent sagging and vibration.

[0018] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
