Description

Technical Field

[0001] This utility model relates to the field of plane mirror processing technology, specifically a plane mirror mount milling fixture. Background Technology

[0002] Planar reflector mounts are usually designed with irregular shapes, and their small size makes them difficult to position and fix. When die-casting this product, due to mass production, individual differences will occur in the die-cast parts, especially related to the mold closing state and whether the reset is in place. The part itself is small and may also have problems such as deformation and local collapse. At the same time, these four sides are closely related to the above-mentioned factors, thus becoming a difficult point in machining.

[0003] CN215615371 U discloses a milling fixture for a reflector seat, including a base. Support legs are fixedly connected to the four corners of the top surface of the base. A positioning platform is fixedly connected to the top of the support legs. A placement groove is formed at the center of the top surface of the positioning platform. A moving groove is connected to the bottom of the inner cavity of the placement groove. The positioning platform passes through the bottom of the inner cavity of the moving groove.

[0004] The existing milling fixtures for mirror mounts have the following disadvantages: the clamping shape of the existing milling fixtures for mirror mounts is relatively fixed, which makes it inconvenient to clamp when processing irregularly shaped mirror mounts, or requires changing the clamping mold. They are highly specific and have a limited range of applications.

[0025] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figures 1 to 5As shown, a milling fixture for a planar reflector mount includes a base 1, an adjustment structure 3, a shaped clamping structure 4, a pad 5, and a lifting structure 6. The top of the base 1 has a movable slot 2, and the base 1 is used to install the overall device. The adjustment structure 3 is located on the top of the base 1, and the shaped clamping structure 4 is located in the adjustment structure 3. The distance between the two shaped clamping structures 4 is adjusted by the adjustment structure 3. The pad 5 is located below the shaped clamping structure 4, and the lifting structure 6 is located in the adjustment structure 3. The pad is used to support the planar reflector mount and prevent the planar reflector mount from sliding down during milling, which would affect the milling work. Furthermore, the height of the pad can be adjusted according to the thickness of the planar reflector mount by the lifting structure.

[0027] The adjustment structure 3 includes a bidirectional threaded rod 301 and a movable block 302. The bidirectional threaded rod 301 is rotatably connected to the movable groove 2, and one end extends out of the movable groove 2. The movable blocks 302 are located at both ends of the movable groove 2. The two movable blocks 302 are threadedly connected to the bidirectional threaded rod 301. A mounting plate 303 is fixedly connected to the top of the movable blocks 302. Rotating the end of the bidirectional threaded rod 301 that extends out of the movable groove 2 synchronously drives the two movable blocks 302 and simultaneously moves the mounting plate 303. The distance between the two mounting plates 303 is adjusted according to the width or length of the plane reflector mount. Guide grooves 7 are opened on both sides of the top of the base 1. Guide rods 8 are fixedly connected in the guide grooves 7. The bottom sides of the mounting plate 303 extend into the guide grooves 7 and are slidably connected to the guide rods 8.

[0028] The irregular clamping structure 4 includes an arc-shaped block 1 401, an arc-shaped block 2 402, an arc-shaped block 3 403, and an arc-shaped block 404. Arc-shaped block 1 401 is located on both sides inside the adjusting structure 3. Arc-shaped grooves 1 405 are formed at both ends of the side of arc-shaped block 1 401 closest to it. Arc-shaped block 2 402 is rotatably connected to arc-shaped groove 1 405. Arc-shaped groove 2 406 is formed at both ends of the side of arc-shaped block 2 402 away from arc-shaped block 1 401. Arc-shaped block 3 403 is rotatably connected to arc-shaped groove 2 406. Arc-shaped groove 3 407 is formed at both ends of the side of arc-shaped block 3 403 away from arc-shaped block 2 402. Arc-shaped block 404 is rotatably connected to the arc-shaped block 404. Inside the three-shaped groove 407, two mounting plates drive the arc-shaped blocks 1 401, 2 402, 3 403, and 4 404 to move closer to both sides of the plane reflector mount. An arc-shaped groove 4 9 is opened on the side of the two mounting plates 303 that are close to each other. The arc-shaped block 1 401 is rotatably connected in the arc-shaped groove 4 9. When encountering an irregularly shaped part, the arc-shaped blocks 1 401, 2 402, 3 403, and 4 404 adjust their angles in the arc-shaped grooves 1 405, 2 406, 3 407, and 4 9 respectively, thereby fitting the edge of the irregularly shaped part and clamping it.

[0029] The lifting structure 6 includes a second movable groove 601, which is located in the middle of the opposite side of the two mounting plates 303. A threaded rod 602 is rotatably connected in the second movable groove 601. A second movable block 603 is provided in the second movable groove 601. One side of the second movable block 603 is fixedly connected to the pad plate 5. A bevel gear 604 is fixedly connected to the top of the threaded rod 602. A bevel gear 605 is meshed with one side of the bevel gear 604. A connecting rod 606 is fixedly connected to one side of the bevel gear 605. One end of the connecting rod 606 extends to the front side of the mounting plate. When encountering a plane reflector seat of different thicknesses, rotating the connecting rod 606 drives the bevel gear 605 to rotate, which in turn drives the bevel gear 604 and the threaded rod 602 to rotate. This drives the second movable block 603 to move in the second movable groove 601, thereby adjusting the distance between the pad plate 5 and the irregular clamping structure 4.
