Description

Technical Field

[0001] The present invention relates to the fields of jewelry processing and gemstone processing, and specifically to a high-efficiency grinding and polishing tool for the vertical and parallel surfaces of gemstones, and particularly to a mechanical processing device with high precision, high stability, high efficiency and wide applicability. Background Art

[0002] Technical Defect 1: Manual processing has safety hazards, low processing efficiency, inability to guarantee precision, and a high product loss rate.

[0003] Technical Defect 2: Limitations of traditional tools. The existing processing method using a 45° triangular block in combination with an octagonal hand conversion has poor stability due to the lack of a fixed point, and the processing precision is significantly affected by human factors.

[0004] The above methods are difficult to meet the requirements of modern gemstone processing for precision, efficiency and loss control. Therefore, there is an urgent need for a tool with precise structure, simple operation, strong adaptability and significantly improved processing quality. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-efficiency grinding and polishing tool for the vertical and parallel surfaces of gemstones, which solves the problems of low processing precision, poor stability and insufficient efficiency in the prior art through a mechanical structure design, while reducing losses and adapting to new and old equipment.

[0006] Technical Solution. The present invention includes four core devices (as shown in the appendix Figures 1-7 ), and its structural features are as follows.

[0007] The vertically installed calibration block device (1) has a trapezoidal structure, and the vertical center is perpendicular to the cross-sectional direction; the installation position of the tool is calibrated by fitting the grinding wheel plane, and the parallelism error of the bottom plate is ensured to be ≤0.05° by combining the balance adjustment screw (304).

[0008] The clamping device (2) includes a copper bushing (202), a V-groove chuck (201), a hexagonal stud (207), a rotating tension ring (205) and a limiting component (203, 204, 206); a clamping force of >300 N is generated through screw drive, and the concentricity error is ≤0.02 mm; the rotating tension ring (205) is tightened by rotating 1.5 turns and loosened by rotating ≥2 turns in the reverse direction.

[0009] The vertical fixing device (3) has a triangular bottom plate (301) equipped with three balance adjustment screws (304), and the balance accuracy is ≤0.03°; the long strip-shaped installation groove (303) adapts to different equipment, and the vertical axis (309) realizes precise positioning through a fine-tuning retaining ring (307) and a tightening knob (308).

[0010] The handgrip device (4) is designed with a streamlined ergonomic shape, and round holes are provided at both ends to connect the clamping device (2) and the linear bearing (403) respectively; the linear bearing (403) is parallel to the vertical axis (309) and supports vertical movement and horizontal rotation. Technical effects

[0011] High precision: The parallelism error between the vertical axis and the grinding disc is ≤0.03mm, and the processing precision is improved to the 0.03mm level.

[0012] High efficiency: The mechanical operation efficiency is more than 10 times higher than that of the traditional method.

[0013] Strong adaptability: It can be compatible with new and old equipment, especially suitable for equipment with uneven workbenches.

[0014] Low loss: The clamping force is stable, reducing the breakage rate of gemstones. Description of the drawings
