Description

Technical Field

[0001] This utility model relates to the field of jewelry carving clamp technology, specifically a jewelry carving clamp with multi-angle adjustment. Background Technology

[0002] Jewelry has become an indispensable accessory in people's daily lives, especially for women, particularly young women. Wearing exquisite jewelry is not only a display of personal style but also an important symbol of fashion and taste. In the current jewelry manufacturing industry, especially in the intricate production of ring-shaped ornaments like bracelets, various specialized clamps are typically used to securely fix and precisely position the bracelet. The main purpose of this is to ensure that the bracelet will not shift or move unexpectedly due to external mechanical forces or vibrations during subsequent carving, polishing, or other decorative processes, thus ensuring that the final product's craftsmanship and aesthetics meet the design expectations.

[0003] In the fine processing of bracelets and jewelry, the diameters and sizes of different bracelets vary significantly. Most commercially available jewelry carving jigs are designed with fixed dimensions, making them unsuitable for all types of bracelets. Operators typically need to pad the jig with soft cloth or filler material to temporarily adjust its gripping range to accommodate bracelets of different sizes. This not only increases the complexity of the operation and reduces efficiency, but also, in some cases, the instability of the soft cloth can affect the carving accuracy and finished product quality. Furthermore, some bracelet carving jigs have a relatively fixed structural design, lacking flexibility and adjustability, making it difficult to adjust the bracelet's posture from multiple angles and directions according to processing requirements during the carving process. This limitation severely restricts the carving technique and increases the operational difficulty. Therefore, this invention provides a multi-angle adjustable jewelry carving jig to solve the aforementioned problems. Utility Model Content

A fixing component for fixing the lifting rod 7 is provided inside the fixing post 6. An adjusting seat 16 is fixedly installed on the top surface of the lifting rod 7. A ball bowl 17 is opened inside the adjusting seat 16. A ball 18 is rotatably installed inside the ball bowl 17. A locking component for locking the ball 18 is provided inside the adjusting seat 16. An mounting seat 31 is fixedly installed on the top surface of the ball 18. An mounting plate 32 is fixedly installed on the surface of the mounting seat 31. A positioning component for fixing a bracelet is provided on one side of the mounting plate 32.

[0024] The mounting assembly includes a connecting frame 2 fixedly mounted on the surface of the base plate 1. A first lead screw 3 is threaded onto the surface of the connecting frame 2. A first knob 4 is fixedly mounted on the bottom end of the first lead screw 3. A clamping plate 5 is rotatably mounted on the top end of the first lead screw 3. By rotating the first knob 4, the clamping plate 5 is driven to move upward. When it cooperates with the base plate 1, the device can be clamped on the worktable, which facilitates subsequent engraving work.

[0025] The fixing component includes a spring groove 10 inside the fixing column 6. A movable rod 11 is slidably installed inside the spring groove 10. A movable block 12 is fixedly installed at one end of the movable rod 11. A first spring 13 is fixedly installed on the surface of the movable block 12 and sleeved on the surface of the movable rod 11. An insert block 14 is fixedly installed on the side of the movable block 12 away from the movable rod 11. The surface of the lifting rod 7 has an insertion hole 15. Multiple sets of insertion holes 15 are provided, and the insertion holes 15 and the insert blocks 14 are arranged in a corresponding manner. Since the lifting rod 7 is slidably installed inside the fixing column 6, the overall height of the device can be adjusted by adjusting the height of the lifting rod 7. The fixing component can control the movement of the insert block 14, allowing the insert block 14 to enter and exit the insertion hole 15, which facilitates the limiting of the lifting rod 7.

[0026] The locking assembly includes a mounting cavity 19 inside the adjusting seat 16. A locking block 20 is slidably mounted inside the mounting cavity 19. A lifting block 21 is fixedly mounted on the bottom surface of the locking block 20. In order to ensure that the locking block 20 can be stably raised and lowered within the mounting cavity 19, a mounting groove 22 is provided inside the mounting cavity 19. A fixing rod 23 is fixedly mounted inside the mounting groove 22. A rectangular block 24 is slidably mounted on the surface of the fixing rod 23. A second spring 25 is fixedly mounted on the bottom end of the rectangular block 24. The second spring 25 is sleeved on the surface of the fixing rod 23.

[0027] A second lead screw 26 is threaded onto the internal part of the adjusting seat 16. A second knob 27 is fixedly mounted on one end of the second lead screw 26, and a push block 28 is rotatably mounted on the end of the second lead screw 26 away from the second knob 27. To ensure that the push block 28 can move stably within the mounting cavity 19, a slider 29 is fixedly mounted on the bottom surface of the push block 28. A groove 30 is provided inside the mounting cavity 19, and the slider 29 is slidably mounted inside the groove 30. By rotating the second knob 27, the push block 28 can be driven away from the lifting block 21, causing the locking block 20 to move down and away from the ball 18, thus... The sphere 18 can rotate freely within the ball bowl 17, thereby adjusting the bracelet carving angle fixed on the arc plate 38 to process it from various angles. Reverse rotation of the second knob 27 drives the push block 28 to approach the lifting block 21. The top surface of the push block 28 is provided with an inclined surface. As the push block 28 moves, the inclined surface contacts the lifting block 21 and pushes the lifting block 21 upward, causing the locking block 20 to move toward the sphere 18 and apply pressure to the sphere 18. Through static friction, it is firmly locked, thereby locking the carving angle and preventing deviation during subsequent carving.

[0028] The positioning component includes a fixed cylinder 33 fixedly mounted on the surface of the mounting plate 32. A third lead screw 34 is threaded inside the fixed cylinder 33. A third knob 35 is fixedly mounted on one end of the third lead screw 34. A movable cylinder 36 is rotatably mounted on the surface of the third lead screw 34. A connecting rod 37 is rotatably mounted on the surface of the movable cylinder 36. An arc-shaped plate 38 is rotatably connected to the end of the connecting rod 37 away from the movable cylinder 36. To ensure that the arc-shaped plate 38 can move stably, a movable groove 40 is provided inside the mounting plate 32. A movable block 39 is fixedly mounted on the surface of the arc-shaped plate 38. The movable block 39 is slidably mounted inside the movable groove 40. By rotating the third knob 35, the movable cylinder 36 can be moved. Under the action of the connecting rod 37, the distance between the arc-shaped plate 38 and the movable cylinder 36 can be adjusted, which is convenient for fixing bracelets of different diameters.

[0029] The working principle of this utility model is as follows: In use, the base plate 1 is placed on the workbench. Rotating the first knob 4 causes the first lead screw 3 to rotate, driving the clamping plate 5 upwards. This clamping plate 5, in conjunction with the base plate 1, secures the device. Pulling the movable rod 11 moves the movable block 12, compressing the first spring 13 and causing the insert block 14 to move out of the insertion hole 15. This allows the lifting rod 7 to move up and down, moving the mounting base 31 and adjusting the arc-shaped plate 38 to a suitable height. Releasing the movable rod 11, under the push of the first spring 13, moves the movable block 12, causing the insert block 14 to insert into the insertion hole 15, thus securing the lifting rod 7 and facilitating subsequent jewelry carving. After adjusting the height of the curved plate 38, place the bracelet jewelry to be processed into the placement slot on the curved plate 38. The surface of the curved plate 38 has multiple sets of placement slots, and the width of each set of placement slots is different, which makes it easy to place different types of bracelets. Rotate the third knob 35 to drive the third lead screw 34 to rotate in the fixed cylinder 33, which drives the moving cylinder 36 to move. Under the action of the connecting rod 37, the curved plate 38 is pushed away from the moving cylinder 36 to accommodate bracelets of different diameters and avoid displacement during carving. Rotating the second knob 27 causes the second lead screw 26 to rotate, moving the push block 28 away from the lifting block 21 and releasing its pushing effect. Subsequently, the locking block 20 moves downward under the action of gravity and the restoring force of the second spring 25, moving away from the ball 18. The ball 18 can rotate freely, thereby adjusting the bracelet carving angle fixed on the arc plate 38 for processing from various angles. Rotating the second knob 27 in the opposite direction causes the second lead screw 26 to rotate, moving the push block 28 toward the lifting block 21, causing the lifting block 21 to move upward, which in turn pushes the locking block 20 upward, applying pressure to the ball 18 and locking it firmly through static friction, thereby locking the carving angle and preventing deviation during subsequent carving.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
