Description

Technical Field

[0001] The utility model relates to the technical field of crystal processing, in particular to a grinding device for crystal processing. Background Art

[0002] Laser crystal is a crystal material that can convert the energy provided by the outside world into highly parallel and monochromatic laser light through an optical resonant cavity. It is the working material of crystal laser. When processing laser crystal, a grinding device is needed to grind the surface to ensure the smoothness of the crystal surface.

[0003] In the prior art, a Chinese patent document with application number: 202122769052.3 discloses a multi-station high-efficiency crystal grinding device, including a base, a rotating shaft movably connected to the upper end of the base, a rotating table fixedly connected to the rotating shaft, a unit workbench fixedly connected to the rotating table through a connecting rod, a side panel fixedly connected to the unit workbench, two side panels are provided, and clamping blocks are movably connected to the sides of the side panels close to each other through connecting shafts, one of which passes through the side panels and is connected to a second drive device. This multi-station high-efficiency crystal grinding device uses multiple unit rotating seats to achieve simultaneous limited clamping of multiple crystals, thereby improving the clamping efficiency. When a single crystal is polished, the rotating table is directly rotated so that another unit rotating seat is aligned with the grinding block to grind the next crystal, thereby improving the grinding efficiency. In addition, the second drive device can be used to flip the crystal and achieve double-sided grinding.

[0004] However, since the clamping blocks in the above technical solution are "U-shaped", when the two ends of the crystal are inserted into the two clamping blocks for clamping and fixing, part of the crystal surface will be located inside the clamping blocks, which cannot be contacted by the grinding block, resulting in incomplete grinding of the crystal surface. In addition, the distance between the two clamping blocks cannot be adjusted, and it cannot be used to clamp and fix crystals of different sizes, and its applicability is poor. Therefore, we propose a crystal processing and grinding device to solve the above problems. Utility Model Content

A crystal processing and grinding device is proposed to solve the shortcomings of the prior art that, due to the "U-shaped" clamping blocks, when the two ends of the crystal are inserted into the two clamping blocks for clamping and fixing, part of the crystal surface is located inside the clamping blocks, which cannot be contacted by the grinding block, resulting in incomplete grinding of the crystal surface; in addition, the distance between the two clamping blocks cannot be adjusted, and it is impossible to clamp and fix crystals of different sizes, resulting in poor applicability.

[0049] The working principle of the utility model: when in use, first connect the first motor 2 and the second motor 9 to an external power supply, and then place the crystal on the top of the two support plates 17. At this time, by starting the first motor 2, the first screw rod 3 can be driven to rotate. At this time, the threaded connection between the first screw rod 3 and the nut 4 can drive the two moving plates 6 to approach or move away from each other, thereby driving the two rectangular clamping plates 8 to approach or move away from each other, and then it is possible to clamp and fix crystals of different sizes, thereby improving the scope of application.

At the same time, the support plate 17 can be moved out when the crystal is rotated and turned over, so as to avoid the support plate 17 blocking the flipping of the crystal. When the support plates 17 are away from each other, the second motor 9 is started and the meshing transmission between the two bevel gears 10 can drive the left shaft 7, the two rectangular clamps 8, the right shaft 7 and the crystal to rotate and adjust, so as to realize the flipping of the crystal. Here, in this way, the crystal can be polished on the other side without disassembling the crystal, which greatly improves the polishing efficiency of the crystal.
