Description

Technical Field

[0001] This utility model relates to the field of optical equipment manufacturing technology, specifically to a mirror mounting and calibration fixture. Background Technology

[0002] As a precision aiming instrument, the holographic sight requires the precise installation of each component in its internal optical path. The reflector is used to receive the light emitted by the light source and reflect it to the next optical element, playing a crucial role in connecting the two. Improper installation of the reflector will cause the optical path to shift or even break, affecting the core function of the holographic sight.

[0003] Holographic sights operate in complex environments and require high levels of image stabilization and shock resistance, necessitating that all components be securely bonded to the outer casing. In actual production, the assembly process does not involve adjusting the optical path before encapsulating the casing. Instead, each component and its attached casing are treated as separate units, which are then assembled last. This means that the production of each component is independent, eliminating the need for optical path adjustment. Therefore, accurately defining the installation position of each optical component is crucial to prevent misalignment after assembly.

[0004] The current method of installing and calibrating reflectors usually relies on manual experience, which results in low accuracy and precision. In most production scenarios, workers judge whether the reflector angle is qualified by visually observing the position of the reflected light spot. However, visual observation is easily affected by ambient light and differences in human vision, leading to large errors in angle judgment. This increases the failure rate of reflector installation, requiring repeated disassembly and adjustment, which significantly increases production costs. Utility Model Content

[0005] In view of the problems existing in the above-mentioned mirror installation and calibration fixtures, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a reflector installation and calibration fixture that quantifies the degree of offset of the reflector installation position and guides the installation and calibration based on the offset data. This solves the problem that the existing reflector calibration methods usually adopt manual methods, which have low accuracy and rely on experience judgment, thus leading to an increased failure rate of reflector installation.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mirror mounting and calibration fixture includes a fixture body. A placement groove is formed on the lower surface of the fixture body, and a workpiece is placed inside the placement groove. A mirror mounting base is fixedly connected to the upper surface of the workpiece. A mounting hole is formed on the upper surface of the placement groove, and an arc-shaped groove is formed on one side of the mounting hole. A laser emitter is fixedly connected inside the arc-shaped groove. An L-shaped support is provided at one end of the fixture body, and a positioning hole is formed on the upper surface of the L-shaped support. A target plate is attached above the positioning hole.

[0009] Preferably, the tooling body and the L-shaped support are integrally formed.

[0010] Preferably, the corners of the L-shaped support column are chamfered.

[0011] Preferably, one side of the reflector mounting base coincides with the inner wall of the mounting hole.

[0012] Preferably, the laser emitter is detachably connected to the tooling body via bolts.

[0013] Preferably, the tooling body is U-shaped.

[0014] Preferably, the target pattern consists of a set of concentric circles and a scale with graduations.

[0015] Preferably, three marking lines are provided around the positioning hole, and the center of the target plate coincides with the center of the positioning hole.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model uses a fixed laser emitter to emit a directional laser, which, after being reflected by a reflector, must accurately fall into the positioning hole of an L-shaped support. Compared with the traditional method of manually observing the light spot and judging the angle, this reduces the failure rate of the reflector installation.

[0018] 2. The tooling body of this utility model is made of high-strength aluminum alloy, which can improve the service life of the device. At the same time, the L-shaped support column has a chamfered corner design to avoid bumps and injuries to the operator, thus improving the safety of use. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a mirror installation and calibration fixture.

[0028] This utility model provides, for example Figure 1-3 The reflector mounting and calibration fixture shown includes a fixture body 1. A placement groove is formed on the lower surface of the fixture body 1, and a workpiece 2 is placed inside the placement groove. A reflector mounting base 3 is fixedly connected to the upper surface of the workpiece 2. A mounting hole is formed on the upper surface of the placement groove, and an arc-shaped groove is formed on one side of the mounting hole. A laser emitter 4 is fixedly connected inside the arc-shaped groove. An L-shaped support 5 is provided at one end of the fixture body 1, and a positioning hole 6 is formed on the upper surface of the L-shaped support 5. A target plate 7 is attached above the positioning hole 6. The target plate 7 has a pattern consisting of a set of concentric circles and a graduated crosshair. Three marking lines are formed around the positioning hole 6 to mark the position of the target plate 7. The center of the target plate 7 coincides with the center of the positioning hole 6.

[0029] During mirror installation, workpiece 2 is placed inside the slot on the lower surface of fixture body 1. Then, the mirror is placed on the upper surface of mirror mounting base 3. Next, the laser emitter 4 is activated so that the laser shines on the surface of the mirror. At this time, the laser shines on the lower surface of L-shaped support 5 after reflection. Then, the angle of the mirror is adjusted so that the reflected laser can be located inside the positioning hole 6. By observing the landing point of the reflected light on the target plate, the degree of offset of the current position of the mirror can be determined so as to calibrate and adjust it.

[0030] The line connecting the center of the laser emitter 4 and the center of the reflector mounting base 3 represents the incident light path direction of the reflector in the holographic sight. Similarly, the line connecting the center of the reflector mounting base 3 and the center of the positioning hole 6 represents the outgoing light path direction of the reflector in the holographic sight. Therefore, when the point of impact is located precisely at the center of the target plate, the current position indicates the correct installation position. The target plate is transparent or semi-transparent, which facilitates clear viewing of the light spot while preventing eye damage from direct laser observation.

[0031] like Figure 1-3 As shown, the tooling body 1 and the L-shaped support column 5 are integrally formed, and the corner of the L-shaped support column 5 is chamfered.

[0032] Using chamfers makes the edges of the device more rounded, preventing workers from getting injured from bumps during installation.

[0033] like Figure 1 As shown, one side of the reflector mounting base 3 coincides with the inner wall of the mounting hole.

[0034] When placing workpiece 2, the side of the mounting hole of the reflector mounting base 3 is aligned with that of the mounting hole to achieve positioning and improve the accuracy of the reflector installation.

[0035] like Figure 1-3 As shown, the laser emitter 4 is detachably connected to the tooling body 1 by bolts.

[0036] The detachable installation of laser emitter 4 facilitates its replacement and maintenance in the future.

[0037] like Figure 1 As shown, the tooling body 1 is U-shaped in general.

[0038] The fixture body 1 is U-shaped, which can balance the weight at both ends of the fixture body 1 and prevent the fixture body 1 from tilting when placed.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
