Description
Technical Field
[0001] This utility model relates to the technical field of crystal processing equipment, specifically a multi-faceted synchronous polishing rotating device for crystals. Background Technology
[0002] In the fields of materials science and precision manufacturing, crystals, due to their unique physical properties, are widely used in high-end products such as optical instruments and semiconductor devices. Crystal polishing rotation technology, as a key factor determining its surface quality and performance, has always been a focus of research and industry. With the rapid development of technology, the requirements for crystal surface precision and production efficiency have reached unprecedented levels. Many existing crystal polishing rotation equipment have shortcomings in their support structures. For example, relying solely on a simple bracket to support the processing table can easily cause displacement or shaking of the processing table during polishing due to the vibration generated by the high-speed rotating crystal and polishing head, leading to deviations in the polished crystal surface and making it difficult to achieve the high-precision surface quality requirements. Traditional clamping devices often use a single fixed mode, which is difficult to adapt to diverse crystal sizes and shapes. Utility Model Content

[0016] Compared with existing technologies, the beneficial effects of this utility model are:
[0017] In this multi-faceted synchronous polishing rotary crystal device, a processing table provides a basic platform for crystal polishing. A rotary servo motor is installed at the center of the top surface of the processing table, and its shaft is connected to a turntable and a replaceable lower clamping plate to drive the crystal to rotate. Side lifting cylinders and back lifting cylinders are installed on the side and back of the processing table. The polishing push cylinder at the top of its piston rod can drive the polishing motor and polishing head to perform polishing operations, realizing multi-faceted polishing. A column is installed on one side of the top of the processing table, and the crystal clamping cylinder and upper clamping plate at the end of its top crossbeam can clamp the crystal to ensure the stability of the crystal during the polishing process.

[0019] In this multi-faceted synchronous polishing rotary device for crystals, the top surface of the lower clamping plate and the bottom surface of the upper clamping plate are equipped with several uniformly spaced anti-slip protrusions.

[0031] Crystal multi-faceted synchronous polishing rotary device, such as Figures 1-3As shown, the equipment includes a processing table 10 for crystal polishing. A rotary servo motor 20 is embedded in the center of the top surface of the processing table 10. A side lifting cylinder 30 and a back lifting cylinder 40 are respectively installed on one side and the back of the processing table 10. A horizontally arranged polishing push cylinder 50 is installed on the top of the piston rod of both the side lifting cylinder 30 and the back lifting cylinder 40. A column 12 is installed on the top of the processing table 10 away from the side lifting cylinder 30. A crossbeam 13 is vertically installed on the top of the outer wall of the column 12. A crystal clamping cylinder 14 is installed at the end of the crossbeam 13, which is coaxially arranged with the rotary servo motor 20. An upper clamping plate 15 is coaxially connected to the bottom of the piston rod of the crystal clamping cylinder 14. A turntable 22 is connected to the rotating shaft of the rotary servo motor 20. A replaceable lower clamping plate 21 is installed on the turntable 22. The end of the extension rod 51 of the polishing push cylinder 50 is also shown. A polishing motor 53 is embedded in the machine, and a polishing head 52 is coaxially connected to the output shaft of the polishing motor 53. The processing table 10 provides a basic platform for crystal polishing. A rotary servo motor 20 is installed at the center of the top surface of the processing table 10. Its rotating shaft is connected to a turntable 22 and a replaceable lower clamping plate 21 to drive the crystal to rotate. A side lifting cylinder 30 and a back lifting cylinder 40 are installed on the side and back of the processing table 10. The polishing push cylinder 50 at the top of its piston rod can drive the polishing motor 53 and the polishing head 52 to perform polishing operations, realizing multi-face polishing. A column 12 is installed on one side of the top of the processing table 10. The crystal clamping cylinder 14 and the upper clamping plate 15 at the end of its top crossbeam 13 can clamp the crystal to ensure the stability of the crystal during the polishing process. These structures work together to enable the device to achieve multi-face synchronous polishing of crystals, improving polishing efficiency and quality.
[0032] It is worth noting that support columns 11 are symmetrically arranged on both sides of the bottom surface of the processing table 10, which allows the processing table 10 to be placed stably on the ground, providing a solid support foundation for the entire polishing device, thereby ensuring the stability and safety of the polishing process.
[0033] Furthermore, a bearing 16 is embedded at the bottom of the piston rod of the crystal clamping cylinder 14, and a plug-in post that engages with the inner ring of the bearing 16 is installed on the top of the upper clamping plate 15, so that the upper clamping plate 15 can rotate flexibly under the drive of the crystal clamping cylinder 14. This not only improves polishing efficiency, but also reduces wear caused by friction and extends the service life of the equipment.
[0034] Specifically, the top edge of the turntable 22 has several evenly spaced and equidistantly arranged connecting holes 23 in a ring. The bottom surface of the lower clamping plate 21 is equipped with connecting rods 24 that are the same number, size, and position as the connecting holes 23 and are plugged in. Through the connecting holes 23 and connecting rods 24, a stable connection between the turntable 22 and the lower clamping plate 21 is achieved. This connection method is simple and quick, and can ensure that the relative position between the two remains unchanged during the polishing process, thereby improving the polishing accuracy.
[0035] The bottom of the connecting socket 23 and the bottom of the connecting rod 24 are both equipped with magnetically connected magnets 25. The magnets 25 further enhance the connection stability between the connecting socket 23 and the connecting rod 24. Even if there is a large vibration during the polishing process, the tight connection between the two can be ensured, and the polishing accuracy will not be reduced due to loose connection.
[0036] In addition, the top surface of the lower clamping plate 21 and the bottom surface of the upper clamping plate 15 are equipped with a number of uniformly spaced anti-slip protrusions 26. The anti-slip protrusions 26 increase the friction between the clamping plate and the crystal, thereby improving the clamping effect and preventing the polishing accuracy from decreasing due to the crystal sliding or shifting during the polishing process.
[0037] It is worth noting that the number of connecting holes 23 and connecting rods 24 is 2-5 sets, which not only ensures a stable connection between the turntable 22 and the lower clamping plate 21, but also makes the structure of the entire device more compact and reasonable.
[0038] Working principle of this multi-faceted synchronous polishing rotary device for crystals:
[0039] First, place the device on a stable surface and support the processing table 10 with the support column 11 to keep it stable. According to the crystal size, select a suitable lower clamping plate 21, align the connecting rod 24 on the bottom surface of the lower clamping plate 21 with the connecting hole 23 on the top edge of the turntable 22, and fix it with the magnetic connection of the magnet 25.
[0040] Then, place the crystal on the lower clamping plate 21, start the crystal clamping cylinder 14, and its piston rod drives the upper clamping plate 15 to descend. The upper clamping plate 15 rotates flexibly through the plug-in column that is engaged with the inner ring of the bearing 16 until the anti-slip protrusion 26 on the top surface of the lower clamping plate 21 and the bottom surface of the upper clamping plate 15 clamp the crystal.
[0041] Next, according to the polishing requirements, the height of the polishing push cylinders 50 on both sides is adjusted by the side lifting cylinder 30 and the back lifting cylinder 40 respectively, and then the extension rod 51 of the polishing push cylinder 50 pushes the polishing motor 53 and the polishing head 52 closer to the crystal.
[0042] Finally, the rotary servo motor 20 is started to drive the turntable 22 and the crystal to rotate. At the same time, the polishing motor 53 is started and the polishing head 52 polishes the crystal. The polishing heads 52 on both sides can work synchronously to achieve multi-face polishing. After polishing is completed, the motor and cylinder are turned off in sequence, the crystal clamping cylinder 14 is released, the crystal is taken out, and the entire polishing process is completed.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
