DETAILED DESCRIPTION

[0013] In order to deepen the understanding and recognition of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described and introduced in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments, and are not intended to limit the embodiments in any form. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-2The utility model provides a technical solution: a CNC processing tool for small accessories, including a processing table 1, a positioning plate 7 is threadedly connected to the middle of the upper end of the processing table 1, and a positioning groove 8 is arranged in the middle of the positioning plate 7. The positioning groove 8 can position the small accessories more quickly and prevent the small accessories from moving when the small accessories are clamped. A plurality of sliding grooves 2 are arranged on the upper end of the processing table 1. The sliding grooves 2 are arranged in a ring with the positioning plate 7 as the center. A sliding block 11 is slidably connected in the sliding groove 2. A moving block 3 is fixedly connected to the upper end of the sliding block 11. A fixed plate 5 is slidably connected to the side end of the moving block 3. A fixed head 4 is fixedly connected to the top of the fixed plate 5. The side end of the fixed head 4 is an arc-shaped structure. The fixed head 4 and the moving block 3 is fixedly connected with a buffer spring 6, which is wound on the fixed plate 5. When the fixed head 4 clamps the small ornaments, the buffer spring 6 can buffer the clamping force to avoid deformation of the small ornaments caused by excessive clamping force. A rotating plate 12 is provided at the lower end of the sliding block 11, and a driving block 16 is provided at the side end of the rotating plate 12. An extrusion bolt 14 is connected to the middle thread of the moving block 3. A moving cylinder 9 is slidably connected to the lower end of the processing table 1, and a hydraulic rod is fixedly connected to the lower end of the moving cylinder 9. An extrusion piece 10 is fixedly connected to the inner wall of the moving cylinder 9. Before processing, observe the shape of the small ornament to understand the position that needs to be clamped. After placing the small ornament on the positioning plate 7, rotate the extrusion bolt 14 in the direction that needs to be clamped.

[0015] The upper end of the rotating plate 12 is provided with an extrusion slope 13, which is opposite to the extrusion bolt 14. Both ends of the extrusion bolt 14 pass through the moving block 3 and the sliding block 11 respectively. The upper end of the rotating plate 12 is hinged to the sliding block 11. The initial state of the rotating plate 12 is an inclined structure. The side end of the rotating plate 12 and the lower end of the sliding block 11 are fixedly connected with a return spring 15. The extrusion bolt 14 on the moving block 3 in the direction to be clamped is rotated, and the lower end of the extrusion bolt 14 squeezes the extrusion slope 13, thereby pushing the rotating plate 12 to rotate, so that the rotating plate 12 changes from an inclined state to a vertical state.

[0016] One side of the driving block 16 is an arc-shaped structure, and the other side of the driving block 16 is fixedly connected with a mounting plate 17, and the mounting plate 17 is a T-shaped structure. The mounting plate 17 and the rotating plate 12 are plugged in, and the rotating plate 12 is located in the middle of the moving cylinder 9. The side end of the extrusion member 10 is an arc-shaped structure, and the thickness of the extrusion member 10 gradually increases from top to bottom. When the moving cylinder 9 moves upward, the extrusion member 10 squeezes the driving block 16, thereby pushing the rotating plate 12 and the moving block 3 to move, and pushing the fixed head 4 to clamp and fix the small ornaments. When it is necessary to control the moving distance of the fixed head 4, the driving block 16 is replaced with driving blocks 16 of different lengths, so as to clamp small ornaments with special structures, which is more adaptable.

[0017] When processing small accessories of different shapes, first observe the shape of the small accessories, determine the position of the fixed head 4 that needs to be clamped, rotate the extrusion bolt 14 in that direction, and the extrusion bolt 14 squeezes the extrusion slope 13, so that the rotating plate 12 changes from an inclined state to a vertical state, and replace the drive blocks 16 of different lengths, place the small accessories on the positioning plate 7, move the moving cylinder 9 upward, and the extrusion piece 10 squeezes the drive block 16, thereby pushing the fixed head 4 to move and clamp the small accessories.
