Description

Technical Field

[0001] This utility model relates to the field of crystal polishing technology, specifically to a BBO crystal polishing device. Background Technology

[0002] BBO crystals (barium β-borate crystals) have excellent optical properties and are widely used in laser frequency doubling, frequency mixing, and optical parametric oscillation. In the production process of BBO crystals, polishing is a key processing step, the purpose of which is to make the crystal surface achieve specific flatness and smoothness requirements.

[0003] However, existing BBO crystal polishing equipment has many shortcomings. Traditional polishing equipment can usually only polish a single crystal at a time, resulting in low processing efficiency and difficulty in meeting the growing market demand. Moreover, when changing materials after crystal polishing, the entire polishing process must be paused for a considerable period of time, waiting for the new crystal to be installed before it can continue. This further prolongs the processing cycle and increases production costs. Utility Model Content

[0004] In view of the problems existing in the above-mentioned BBO crystal polishing device, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide a BBO crystal polishing device that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A BBO crystal polishing device includes a base shell and a rotating rod. The rotating rod is rotatably mounted on the middle of the upper surface of the base shell, and its lower end extends to the bottom of the base shell.

[0024] 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.

[0025] This utility model discloses a BBO crystal polishing device.

[0026] Reference Figure 1-3 A BBO crystal polishing device includes a base shell 1 and a rotating rod 2. The rotating rod 2 is rotatably mounted in the middle of the upper surface of the base shell 1, and its lower end extends to the bottom of the base shell 1. A first motor 11 is fixedly mounted in the middle of the lower surface of the base shell 1, and the output end of the first motor 11 is fixedly connected to one end of the rotating rod 2. A mounting plate 3 is fixedly mounted on the upper side of the rotating rod 2, and a hydraulic cylinder 4 is fixedly mounted on the upper surface of the mounting plate 3. A top plate 5 is fixedly mounted at the end of the piston rod of the hydraulic cylinder 4. Fixing tubes are fixedly mounted on both sides of the upper surface of the mounting plate 3. 8. A movable rod 9 is movably connected inside the fixed tube 8. The upper end of the movable rod 9 is fixedly connected to the top plate 5, so that the top plate 5 can move stably. Turntables 7 are rotatably arranged on both sides of the upper surface of the bottom shell 1. Multiple placement slots are distributed in a circular array on the upper surface of the turntables 7. Clamping mechanisms are provided on the inner side of the multiple placement slots. One end of the top plate 5 extends above one placement slot. A polishing machine 6 is fixedly arranged on the lower surface of the top plate 5 and above the placement slot. A transmission mechanism that drives the turntables 7 to rotate is provided inside the bottom shell 1.

[0027] Reference Figure 1-3 The clamping mechanism includes clamping plates 13 and threaded rods 14. Multiple clamping plates 13 are slidably disposed inside the corresponding placement slots. A threaded hole is opened on one side of the placement slot, and the threaded rod 14 is threadedly sleeved inside the threaded hole. One end of the threaded rod 14 is rotatably connected to the clamping plate 13. When the threaded rod 14 rotates, it moves relative to the threaded hole, thereby driving the clamping plate 13 to move. This allows for stable clamping and positioning of the crystal in the placement slot. The longitudinal section of both the clamping plate 13 and the placement slot is rectangular. Both sides of the clamping plate 13 abut against the inside of the placement slot, allowing the clamping plate 13 to slide stably within the placement slot. A knob is fixedly sleeved on the end of the threaded rod 14 away from the clamping plate 13 for easy rotation of the threaded rod 14. The clamping plate 13 is made of rubber to minimize damage to the crystal.

[0028] Reference Figure 1-3 The transmission mechanism includes a first gear 12 and a second gear. A rotating plate 10 is fixedly sleeved on the rod wall of the rotating rod 2 and located inside the bottom shell 1. A transmission rod is rotatably mounted on the upper surface of the rotating plate 10 away from the rotating rod 2. Vertical rods are fixedly mounted on the lower surfaces of the two turntables 7. The lower ends of the vertical rods extend to the inner side of the bottom shell 1. The two first gears 12 are fixedly sleeved on the lower ends of the corresponding vertical rods. The second gear is fixedly sleeved on the upper end of the transmission rod. The second gear meshes with the first gear 12 on one side. A second motor 15 is fixedly mounted on the lower surface of the rotating plate 10. The output end of the second motor 15 is fixedly connected to the lower end of the transmission rod. When the rotating rod 2 drives the grinder to rotate above the placement slot on one side, the rotating plate 10 will drive the second gear 12 to mesh with the first gear 9 on that side, which will drive the turntable 7 to rotate. This will allow multiple crystals in the placement slots to be rotated sequentially to the bottom of the grinder 6 for grinding.

[0029] In this utility model, when in use, first adjust the clamping mechanism by rotating the knob on the threaded rod 14 according to the size of the BBO crystal to be polished. When the threaded rod 14 rotates, it will move relative to the threaded hole because it is threadedly connected to the threaded hole on the placement groove, thereby driving the clamping plate 13 to slide in the placement groove, placing multiple BBO crystals in the placement grooves of the two side turntables 7 respectively, and adjusting the position of the clamping plate 13 to stably clamp and limit the crystal.

[0030] Start the first motor 11, which drives the rotating rod 2 to rotate. The rotating rod 2 drives the mounting plate 3 to rotate. The hydraulic cylinder 4, top plate 5, fixed pipe 8, movable rod 9 and other components on the mounting plate 3 rotate accordingly. When the top plate 5 drives the grinder 6 to rotate above the turntable 7 on one side, start the second motor 15. The second motor 15 drives the transmission rod to rotate. The transmission rod drives the second gear fixedly sleeved on its upper end to rotate. Since the second gear is meshed with the first gear 12 on the vertical rod below the turntable 7 on this side, the rotation of the second gear will drive the first gear 12 to rotate, and then drive the turntable 7 to rotate. When the turntable 7 rotates, the crystals in its placement slot rotate sequentially to the bottom of the grinder 6.

[0031] During this process, hydraulic cylinder 4 is activated, and the piston rod of hydraulic cylinder 4 pushes the top plate 5 downward. The movable rod 9 slides downward in the fixed tube 8 to ensure that the top plate 5 descends stably. After the top plate 5 drives the grinding machine 6 to descend to the appropriate position, the grinding machine 6 is activated to grind the BBO crystal below. At the same time, the staff can perform crystal loading and unloading operations on the turntable 7 on the other side.

[0032] Once all the crystals on one side of the turntable 7 have been polished, the first motor 11 is restarted, and the rotating rod 2 rotates 180°, moving the polishing machine 6 to the other side of the turntable 7. The polishing operation is repeated. This cycle continues, polishing the BBO crystals until all crystals have been processed.

[0033] 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.
