Description

Technical Field

[0001] The utility model relates to the technical field of ring processing, in particular to a fixed clamping device used for ring processing. Background Art

[0002] Rings often need to be polished during production. Polishing refers to a machining method that uses a regularly shaped grinding tool to remove excess material from the workpiece surface to ensure that the geometric shape, dimensional accuracy, surface roughness and surface layer quality meet the design requirements.

[0003] Announcement No. CN219229215U discloses a locking device for ring processing, which includes a base, on which a base column is provided for the ring to be mounted, a limit block for the ring to be placed is circumferentially provided on the outer wall of the base column, a contact block for fixing the ring is provided on the side of the limit block away from the base column, a gap between the contact block and the base column constitutes an accommodating channel for the ring to be placed, and a fixing component for fixing the contact block is provided on the side of the contact block away from the base column, which can improve the effect of the ring being easily displaced during the processing.

[0004] However, the base column used to fix the ring in the above solution is a fixed-size structure. Since people's fingers are of different thicknesses, it cannot be adjusted when processing rings of different sizes, and the scope of use is limited.

[0005] Therefore, we propose a fixed clamping device for ring processing to solve the above-mentioned problems. Utility Model Content

The adjusting mechanism 6 is rotatably mounted on a rotating disk 61, a worm wheel 62 and a worm 63 in the truncated table 11, the connecting tube 12 and the rectangular seat 13, respectively. A spiral convex rail 64 is arranged on the front side of the rotating disk 61, and a rail groove slidably connected to the spiral convex rail 64 is arranged on the bottom of the slider 3. One end of the worm wheel 62 is fixed to the rear side of the rotating disk 61, and the worm 63 is meshed with the worm wheel 62. Both ends of the worm 63 are It extends to the outside of the rectangular seat 13 and is provided with a hexagonal socket 10. The ring is put on the locking block 5. The worm 63 is rotated by inserting the hexagonal wrench into the hexagonal socket 10. The worm 63 drives the rotating disk 61 to rotate through the worm wheel 62. When the rotating disk 61 rotates, the multiple sliders 3 slide in the slide groove 2 through the cooperation of the rail groove and the spiral convex rail 64, so that they move away from or approach each other. When moving away, the locking block 5 abuts against the inner wall of the ring to fix it for subsequent grinding.

[0028] like Figure 3 As shown, the clamping mechanism 8 includes an L-shaped folding rod 81 and a clamping plate 82 slidably installed on one side of the arc-shaped surface of the locking block 5. The top end of the L-shaped folding rod 81 extends toward the arc-shaped surface of the locking block 5.
