Description

Technical Field

[0001] This utility model relates to the field of jewelry processing equipment, and in particular to a double-headed jewelry engraving machine. Background Technology

[0002] Carving is a common process in jewelry making. For example, smooth patterns are carved on both sides of hollow earrings to enhance the beauty of the jewelry. In addition, bracelets, rings and other jewelry are often made with carved patterns to create specific styles and achieve an eye-catching effect.

[0003] Traditionally, the finishing process involves hand-carving. Workers hold the workpiece and place it onto a high-speed rotating cutter head to create the design. After each pattern is finished, the workpiece must be manually rotated or moved to create the next pattern; this process is repeated until multiple patterns are created on the surface. Hand-carving is extremely dependent on the worker's eyesight, concentration, and operational precision. Even slight deviations can directly affect the quality of the pattern, and for precious metals, such errors incur high costs. Furthermore, due to the small size and thinness of the jewelry, slipping or distraction can pose a risk of mechanical injury.

[0004] Currently, some automated turning equipment has emerged, which mainly uses a motor to drive the cutting tool. By inputting a program into the equipment, the cutting tool is driven to follow a predetermined path, leaving turning marks on the surface of the fixed workpiece. Although such equipment achieves automation, since jewelry often requires multiple patterns arranged in a circumferential direction, the movement trajectory of the cutting tool becomes very complex. In addition to lifting and rotating, the tool holder also needs to deflect at a certain angle on a plane. The processing time for each workpiece is also relatively long, resulting in low production efficiency. When processing large batches of jewelry, it is often difficult to keep up with the production schedule. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a double-headed jewelry engraving machine, which can solve the problems of unstable engraving quality and low production efficiency in existing jewelry engraving processing.

[0006] This utility model is achieved through the following technical solution:

[0007] A double-headed jewelry engraving machine includes: a first tool holder, comprising: a first engraving cutter and a first linear module; the first engraving cutter is slidably connected to the first linear module, and the first linear module is used to drive the first engraving cutter to reciprocate and move up and down; a second tool holder, comprising: a second engraving cutter and a second linear module; the second engraving cutter is slidably mounted on the second linear module, and the second linear module is used to drive the second engraving cutter to reciprocate and move up and down; a turntable, having at least two sets of clamps arranged along the circumferential direction, including a first clamp and a second clamp belonging to the same set. The fixture, and a third and fourth fixture as a group thereof; a turntable drive source for driving the turntable to rotate; a fixture drive source for driving the first, second, third, and fourth fixtures to rotate about their own central axis; when the turntable rotates, the first, second, third, and fourth fixtures revolve about the central axis of the turntable, so that the first and second fixtures are respectively positioned below the first and second tool holders, or the third and fourth fixtures are respectively positioned below the first and second tool holders.

[0008] Furthermore, a cylindrical boss is formed on the first clamp, the second clamp, the third clamp, and the fourth clamp. An annular groove is formed on the outer periphery of the cylindrical boss. The annular groove is suitable for the circular ornament to be embedded and snapped in, so that the circular ornament is tightly fitted on the outer periphery of the cylindrical boss.

[0009] Furthermore, the jewelry double-head engraving machine also includes a control module; the control module is simultaneously electrically connected to the first linear module, the second linear module, the turntable drive source, and the fixture drive source to control the coordinated operation of each mechanism.

[0010] Furthermore, the first turning tool includes a first rotating cutter head, which is positioned above the fixture; the second turning tool includes a second rotating cutter head, which is positioned above the fixture; the first rotating cutter head and the second rotating cutter head are arranged opposite to each other.

[0011] Furthermore, the jewelry double-head engraving machine also includes: a worktable; the first tool holder, the second tool holder, the turntable, and the turntable drive source are all arranged on the top of the worktable.

[0012] Furthermore, the jewelry double-head engraving machine also includes: a chip-proof cover; the chip-proof cover is fixed above the worktable and covers the first tool holder, the second tool holder, and the turntable.

[0013] Furthermore, the first linear module includes: a first guide rail, a first slider, and a first module motor; the first cutting tool is fixed on the first slider, and the first module motor is used to drive the first slider to reciprocate along the first guide rail; the first guide rail is arranged vertically.

[0014] Furthermore, the second linear module includes: a second guide rail, a second slider, and a second module motor; the second cutting tool is fixed on the second slider, and the second module motor is used to drive the second slider to reciprocate along the second guide rail; the second guide rail is arranged vertically.

[0015] Furthermore, the clamp drive source is a motor or a rotary cylinder.

[0016] Furthermore, the turntable drive source is a motor or a rotary cylinder.

[0017] Compared with existing technologies, the beneficial effects that this utility model can achieve are as follows:

[0018] During operation, the turntable drive source drives the turntable to rotate. Two sets of four clamps on the turntable revolve around the central axis of the turntable, causing two clamps in the same set (the first clamp and the second clamp, or the third clamp and the fourth clamp) to move below the first and second tool holders. The first and second turning cutters reciprocate vertically through the first and second linear modules, respectively, while their cutting heads rotate continuously. When the cutting head presses down onto the workpiece surface, a pattern is machined. When the cutting head rises and leaves the workpiece surface, the clamp drive source drives the clamps to rotate, causing the workpiece on the clamp to rotate, moving the position on the workpiece where the next pattern will be machined to be directly below the cutting head. Then, the cutting head presses down again to machine the next pattern. This process is repeated until multiple uniform and smooth patterns are machined onto the entire surface of the workpiece. After machining, the turntable continues to rotate, causing the fixture to revolve and transfer the machined workpiece to the unloading position. At the same time, another set of fixtures is moved to the bottom of the tool holder, allowing the next set of workpieces to be machined to enter under the tool head to wait for machining.

[0019] (1) This utility model achieves full automation of the surface engraving process of jewelry, eliminating reliance on manual labor, saving a significant amount of labor costs, and freeing production personnel from prolonged observation and manual rotation of workpieces, thus avoiding potential mechanical injuries during production. Moreover, the pattern quality is stable and consistent, and the yield rate is significantly improved. (2) Furthermore, compared to previous engraving equipment that solely uses a cutter head drive, this utility model breaks down the original complex engraving action into multiple individual actions, which are independently completed by different mechanisms such as the cutting tool, turntable, and fixture. The cutting tool performs lifting and cutting head rotation actions, the fixture performs workpiece rotation actions, and the turntable performs station switching actions. These individual actions can be performed synchronously. For example, during the lifting and lowering of the cutting head, the fixture simultaneously rotates the workpiece, thereby reducing the time required for each production cycle and significantly improving production efficiency. (3) This utility model adopts a double-cutter head combined with two sets of fixtures, allowing two workpieces to be processed simultaneously at a time. This dual-output form of this utility model improves engraving efficiency and is beneficial for ensuring production progress when processing large quantities of jewelry. Of course, depending on the needs, a four-head cutter head combined with eight sets of fixtures can be used to further improve production efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model discloses a double-headed jewelry engraving machine, which is used to engrave patterns of corresponding shapes on the surface of jewelry workpieces 1, especially for engraving patterns on the surface of circular workpieces 1 (such as rings, bracelets, hollow earrings, etc.). For ease of understanding, Figure 1 A schematic diagram is shown of a circular workpiece 1 with one of the patterns machined on its surface.

[0032] See Figures 2-5 This double-headed jewelry cutting tool includes: a first tool holder 10, a second tool holder 20, a turntable 30, a turntable drive source 80, a clamp, and a clamp drive source 90.

[0033] The first tool holder 10 includes a first swivel cutter 11 and a first linear module 12. The first swivel cutter 11 is slidably mounted on the first linear module 12, and the first linear module 12 drives the first swivel cutter 11 to reciprocate up and down along its guide rail. (See reference) Figure 5 The first turning cutter 11 has a continuously rotating first rotating cutter head 111. The method of driving the first rotating cutter head 111 inside the first turning cutter 11 is known technology, and its internal structure will not be described in detail. Similarly, the second tool holder 20 includes a second turning cutter 21 and a second linear module 22. The second turning cutter 21 is slidably mounted on the second linear module 22, which drives the second turning cutter 21 to reciprocate up and down along its guide rail. The second turning cutter 21 has a continuously rotating second rotating cutter head 211. The method of driving the second rotating cutter head 211 inside the second turning cutter 21 is known technology, and its internal structure will not be described in detail.

[0034] At least two sets of four fixtures are arranged along the circumferential direction on the surface of the turntable 30. The first set consists of a first fixture 40 and a second fixture 50, and the second set consists of a third fixture 60 and a fourth fixture 70. The fixtures are used to hold and fix the workpiece 1 to be machined. In one embodiment shown in the figure, two machining tools and two sets of four fixtures are arranged on the turntable 30; in other embodiments, four machining tools and four sets of eight fixtures may also be arranged on the turntable 30, or other multiples of the number of machining tools and fixtures may be arranged, the specific quantity depending on production needs.

[0035] The turntable drive source 80 can be implemented by a motor or a rotary cylinder, used to drive the turntable 30 to rotate. When the turntable 30 rotates, it will synchronously drive each clamp on the turntable 30 to rotate synchronously. The number of clamp drive sources 90 matches the number of clamps one by one, and can also be implemented by a motor or a rotary cylinder, used to drive the clamps to rotate on the turntable 30. Specifically, in this embodiment, there are 4 clamp drive sources 90, which are used to drive the first clamp 40, the second clamp 50, the third clamp 60 and the fourth clamp 70 to rotate around their own central axis, thereby causing the workpiece 1 clamped on the clamps to rotate.

[0036] When the turntable 30 rotates, the first clamp 40, the second clamp 50, the third clamp 60 and the fourth clamp 70 revolve around the central axis of the turntable 30, thereby placing the first clamp 40 and the second clamp 50 below the first tool holder 10 and the second tool holder 20 respectively, or placing the third clamp 60 and the fourth clamp 70 below the first tool holder 10 and the second tool holder 20 respectively.

[0037] The working principle of this utility model is as follows:

[0038] After workpiece 1 is loaded onto the fixture and fixed, the turntable drive source 80 drives the turntable 30 to rotate. The two sets of four fixtures on the turntable 30 revolve around the central axis of the turntable 30, thereby moving the two fixtures of the first set to below the first tool holder 10 and the second tool holder 20. The first cutting cutter 11 and the second cutting cutter 21 respectively reciprocate in a vertical direction through the first linear module 12 and the second linear module 22, while the cutting heads of the first cutting cutter 11 and the second cutting cutter 21 continue to rotate. When the cutting head presses down to the surface of workpiece 1, a pattern is machined; when the cutting head rises and leaves the surface of workpiece 1, the fixture drive source 90 drives the fixture to rotate, thereby causing workpiece 1 on the fixture to rotate, rotating the position on workpiece 1 where the next pattern is to be machined to be directly below the cutting head, and then the cutting head presses down again to machine the next pattern. This process is repeated until multiple uniform and smooth patterns are machined onto the entire surface of workpiece 1. After machining, the turntable 30 continues to rotate, causing the fixture to revolve and transfer the machined workpiece 1 to the unloading position. At the same time, the two fixtures of the second set are moved to the bottom of the tool holder, so that the next set of workpieces 1 to be machined can enter the bottom of the tool head to wait for machining.

[0039] The technical advantages of this utility model are as follows:

[0040] (1) This utility model realizes full automation of the surface carving process of jewelry, eliminating reliance on manual labor, saving a lot of labor costs, and eliminating the need for production personnel to watch and manually rotate workpiece 1 for a long time, avoiding potential mechanical damage during production. Moreover, the quality of the pattern is stable and consistent, and the yield rate is significantly improved. (2) In addition, compared with the previous single-head-driven carving equipment, this utility model breaks down the original compound carving action into multiple single actions, which are independently completed by different mechanisms such as cutting tool, turntable 30, and fixture. The cutting tool performs the lifting and rotating actions of the cutting head, the fixture performs the rotating action of workpiece 1, and the turntable 30 performs the switching action of the work station. These single actions can be performed synchronously. For example, during the lifting and lowering process of the cutting head, the fixture simultaneously rotates workpiece 1, thereby compressing the time required for each production cycle and significantly improving production efficiency. (3) This utility model adopts a double cutting head combined with two sets of fixtures, which can process two workpieces 1 at the same time. This dual-output form of this utility model improves the carving efficiency and is conducive to ensuring production progress when processing a large number of jewelry. Of course, depending on the needs, a four-head cutter head combined with eight sets of fixtures can be used to further improve production efficiency.

[0041] Preferably, see Figure 6Each of the first clamp 40, second clamp 50, third clamp 60, and fourth clamp 70 has a cylindrical boss 41 on its top. An annular groove 42 is formed around the outer periphery of the cylindrical boss 41. This annular groove 42 is suitable for internal engagement, allowing the annular workpiece 1 to be tightly fitted onto the outer periphery of the cylindrical boss 41, thus fixing and clamping the workpiece 1. When the clamps rotate, they cause the annular workpiece 1 to rotate, aligning different positions of the workpiece 1's edge with the upper cutting head.

[0042] Preferably, the present invention further includes a control module 100, which is electrically connected to the first linear module, the second linear module, the turntable drive source 80, and the fixture drive source 90, thereby controlling the various mechanisms to work collaboratively according to the process. The specific electrical control methods and principles are known to those skilled in the art and will not be described in detail here.

[0043] Preferably, the first rotating cutter head 111 and the second rotating cutter head 211 are arranged opposite to each other, which makes the structure more compact and also helps the debris generated by the two cutter heads during the processing to fall in a relatively concentrated position, making it easier to clean up uniformly.

[0044] Preferably, the present invention also includes a worktable 110, which serves as the mounting surface and processing platform for the equipment. The first tool holder 10, the second tool holder 20, the turntable 30, and the turntable drive source 80 are all arranged on the top of the worktable 110.

[0045] In a further preferred embodiment, the present invention also includes a chip-proof cover (not shown) as the outer shell of the worktable 110. The chip-proof cover is fixed above the worktable 110 and covers the first tool holder 10, the second tool holder 20, and the turntable 30 to prevent debris generated during the machining process from splashing outside the equipment.

[0046] The first linear module 12 specifically includes: a first guide rail, a first slider, and a first module motor; a first cutting tool 11 is fixed on the first slider, and the first module motor is used to drive the first slider to reciprocate along the first guide rail; the first guide rail is arranged vertically. Similarly, the second linear module 22 includes: a second guide rail, a second slider, and a second module motor; a second cutting tool 21 is fixed on the second slider, and the second module motor is used to drive the second slider to reciprocate along the second guide rail; the second guide rail is arranged vertically.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
