[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: As Figures 1-5 shown, the present utility model provides a positioning tooling for drilling and processing of bracelets, including an operating table 1. Two moving frames 11 are in sliding contact with the upper surface of the operating table 1. Fixing brackets 3 are fixedly installed on the upper surfaces of the two moving frames 11. Limiting clamps 31 are detachably installed on the mutually approaching sides of the two fixing brackets 3. And the mutually approaching sides of the two limiting clamps 31 are in movable contact with the outer surface of the round beads, used to position and limit the round beads, so that they are located directly below the drilling device and prevent the round beads from rotating during drilling; Two support plates 2 are fixedly installed on the lower surface of the operating table 1, used to support the operating table 1 and install the collection box 21. A collection box 21 is slidably installed between the two support plates 2.

[0021] Connecting blocks 32 are fixedly installed on the mutually remote sides of the two limiting clamps 31, and the connecting blocks 32 are movably inserted into the fixing bracket 3. A limiting block 33 is slidably installed in the fixing bracket 3, and the limiting block 33 is movably clamped inside the connecting block 32, used to limit the limiting clamp 31. When in use, when the limiting block 33 is clamped inside the connecting block 32, at this time the limiting clamp 31 cannot move, so that the limiting clamp 31 can be limited.

[0022] By adopting the above technical solution, the limiting block 33 can limit the limiting clamp 31.

[0023] A pull rod 35 is rotatably installed inside the limit block 33, and the top end of the pull rod 35 rotatably penetrates through the fixed frame 3. Two limit strips 36 are fixedly installed on the outer surface of the pull rod 35, and the limit strips 36 are movably clamped inside the fixed frame 3 to limit the pull rod 35. When in use, when the limit strip 36 is clamped inside the fixed frame 3, the pull rod 35 cannot move at this time, so that the pull rod 35 can be limited.

[0024] By adopting the above technical solution, the limit strip 36 can limit the pull rod 35.

[0025] A second spring 34 is fixedly installed on the upper surface of the limit block 33, and one end of the second spring 34 away from the limit block 33 is fixedly connected inside the fixed frame 3 to drive the limit block 33 to move downward. When in use, the pull rod 35 is pulled upward to drive the limit block 33 to move upward. At this time, the second spring 34 contracts under the action of an external force. When the hand is released, the second spring 34 releases the contracted force to push the limit block 33 to move downward, so that the limit block 33 is clamped inside the connecting block 32 to limit the limit clip 31.

[0026] By adopting the above technical solution, the second spring 34 can drive the limit block 33 to move downward.

[0027] Sliders 13 are fixedly installed on both sides of the moving frame 11 close to the operation table 1, and the sliders 13 are slidably arranged inside the operation table 1. Two double-headed screws 14 are rotatably installed inside the operation table 1, and the sliders 13 are threadedly connected to the double-headed screws 14 to drive the moving frame 11 to move. When in use, the rotation of the double-headed screw 14 drives the slider 13 to move, and the movement of the slider 13 drives the moving frame 11 to move.

[0028] By adopting the above technical solution, the double-headed screw 14 can drive the moving frame 11 to move.

[0029] A motor 15 is fixedly installed on the side of the operation table 1, and one end of the output shaft of the motor 15 is rotatably arranged inside the operation table 1. Two first bevel gears 16 are fixedly installed on the outer surface of the output shaft of the motor 15. A second bevel gear 17 is fixedly installed at the center of one end of the double-headed screw 14 close to the output shaft of the motor 15, and the first bevel gear 16 and the second bevel gear 17 are meshed to drive the double-headed screw 14 to rotate. When in use, the motor 15 is turned on to drive the first bevel gear 16 to rotate. The rotation of the first bevel gear 16 drives the second bevel gear 17 to rotate, and the rotation of the second bevel gear 17 drives the double-headed screw 14 to rotate.

[0030] By adopting the above technical solution, the motor 15 can drive the double-headed screw 14 to rotate.

[0031] Two rotating plates 12 are rotatably installed in the operating table 1 to cover the discharge port. A rotating shaft 121 is fixedly installed on both sides of the rotating plate 12, and the rotating shaft 121 is rotatably set inside the operating table 1. A first spring 122 is fixedly installed on the outer surface of the rotating shaft 121, and one end of the first spring 122 away from the rotating shaft 121 is fixedly connected to the inside of the operating table 1.

[0032] By adopting the above technical solution, the rotating plate 12 can cover the discharge port.

[0033] Four fixed blocks 18 are fixedly installed in the operating table 1, and a connecting rod 19 is rotatably installed in the fixed block 18, and transmission is carried out between the connecting rod 19 and the rotating shaft 121 through a synchronous wheel and a synchronous belt. A transmission gear 191 is fixedly installed at the center of one end of the connecting rod 19 away from the synchronous wheel, and a toothed plate 131 is fixedly installed on the side of the slider 13, and the toothed plate 131 and the transmission gear 191 are movably engaged to drive the rotating plate 12 to rotate. When in use, the toothed plate 131 is moved by the movement of the slider 13. When the toothed plate 131 and the transmission gear 191 are engaged, the transmission gear 191 is driven to rotate, and the connecting rod 19 is driven to rotate through the rotation of the transmission gear 191, and the rotating shaft 121 is driven to rotate through the rotation of the connecting rod 19, and the rotating plate 12 is driven to rotate through the rotation of the rotating shaft 121.

[0034] By adopting the above technical solution, the slider 13 can drive the rotating plate 12 to rotate.

[0035] Working principle: first, insert the connection block 32 of the limit clip 31 into the fixing frame 3, rotate the pull rod 35 to drive the limit bar 36 to rotate, so that the limit bar 36 is separated from the limiting groove, and then the second spring 34 releases the contraction force, pushing the limit block 33 to move downward, so that the limit block 33 is stuck in the connection block 32, and the limit clip 31 is limited, completing the installation between the limit clip 31 and the fixing frame 3;

[0036] Secondly, place the ball between the two limiting clamps 31, turn on the motor 15 to drive the first bevel gear 16 to rotate, the rotation of the first bevel gear 16 drives the second bevel gear 17 to rotate, the rotation of the second bevel gear 17 drives the double-headed screw 14 to rotate, the rotation of the double-headed screw 14 drives the slider 13 to move, the movement of the slider 13 drives the moving frame 11 to move, the movement of the moving frame 11 drives the fixed frame 3 to move, and the movement of the fixed frame 3 drives the limiting clamp 31 to move, so that the side surfaces of the two limiting clamps 31 that are close to each other contact with the outer surface of the ball, so as to limit and position the ball;

[0037] Then, a drilling device is used to drill the round beads. When the drilling is completed, the limiting clamp 31 is driven by the motor 15 to move, so that the side surfaces of the limiting clamp 31 that are close to each other do not contact the outer surface of the round beads. At this time, the round beads fall downward, and the movement of the slider 13 drives the toothed plate 131 to move. When the toothed plate 131 meshes with the transmission gear 191, the transmission gear 191 is driven to rotate. The rotation of the transmission gear 191 drives the connecting rod 19 to rotate. The rotation of the connecting rod 19 drives the rotating shaft 121 to rotate. The rotation of the rotating shaft 121 drives the rotating plate 12 to rotate, opening the discharge port. At this time, the processed round beads fall into the inside of the collection box 21 through the discharge port, realizing the automatic discharging of the round beads;

[0038] Finally, when the processing is completed, the collection box 21 is pulled out, and the drilled round beads are taken out.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
