Description

Technical Field

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

[0002] Necklaces, rings and other jewelry are common accessories worn in daily life. In order to enhance the decorative effect of rings, various patterns are usually made on the surface of the ring during the manufacturing process.

[0003] Chinese utility model patent CN208743703U discloses a high-efficiency ring engraving machine, including a frame, a mounting base, a tooling fixture rotatably connected to the mounting base, and an engraving knife mounted on the frame for engraving rings on the tooling fixture. The tooling fixture includes a mounting rod rotatably connected to the mounting base via a connecting mechanism, a ring mold sleeved on the mounting rod for fitting rings, and a lubrication component set on the mounting base for allowing relative rotation between the ring mold and the mounting base after the ring mold comes into contact with the mounting base. The circumferential sidewall of the ring mold has multiple expansion grooves that communicate with through-shaft holes through which the mounting rod passes. The expansion grooves form multiple expansion claws on the ring mold. A drive block is fixed on the end of the mounting rod near the ring mold for driving the multiple expansion claws to bend toward opposite sides after being inserted into the through-shaft holes.

[0004] As described above, with this type of engraving machine, once the ring pattern on the ring mold is engraved, the operator needs to stop driving the engraving cutter, remove the engraved ring from the ring mold, and install the next ring to be engraved on the ring mold before operating the engraving cutter to engrave the next ring. This results in low work efficiency. Utility Model Content

[0005] In order to enable the engraving tool to continuously engrave rings and thus improve work efficiency, this utility model provides a high-efficiency ring engraving machine.

[0006] The high-efficiency ring engraving machine provided by this utility model adopts the following technical solution:

[0007] A high-efficiency ring engraving machine includes a frame, a tool holder mounted on the frame, and an engraving device mounted on the tool holder. The engraving device includes an engraving cutter and a driving mechanism for driving the engraving cutter to engrave the ring. A horizontally arranged turntable is rotatably connected to the frame. Two sets of tooling fixtures are symmetrically arranged on the turntable. A rotating component for driving the turntable to rotate is provided on the frame. The rings on the two sets of tooling fixtures are processed alternately.

[0008] By adopting the above technical solution, the rotating component is used to drive the turntable to rotate. By setting two sets of tooling fixtures on the turntable, during operation, the rotation of the turntable causes the two sets of tooling fixtures to move alternately to below the cutting tool. The drive mechanism drives the cutting tool to cut the ring. When the cutting tool is cutting the ring on one set of tooling fixtures, the operator can remove the ring that has been cut on the other set of tooling fixtures from one side of the turntable and install the next ring to be cut on the tooling fixture. During operation, the alternating movement of the two sets of tooling fixtures allows the cutting tool to cut the rings to be processed more continuously, thereby improving work efficiency.

[0009] Optionally, the frame is provided with a support assembly to improve the stability of the turntable.

[0010] By adopting the above technical solution, the offset of the turntable position will cause the tooling fixture position to shift, and the offset of the tooling fixture position will cause the position of the processed ring to change. The setting of the support component improves the stability of the turntable during the processing, reduces the possibility of the ring position shift affecting the processing accuracy, and at the same time reduces the possibility of loosening between the turntable and the rotating component connection during long-term operation.

[0011] Optionally, the support assembly includes multiple support rods, and a circular guide groove is formed on the lower surface of the turntable. The rotation center axis of the guide groove is on the same vertical line as the rotation center axis of the turntable. The support rods are mounted on the frame and are vertically arranged. Multiple support rods are distributed circumferentially along the guide groove, and the upper surface of the support rods abuts against the inner top wall of the guide groove.

[0012] By adopting the above technical solution, multiple support rods always play a role in limiting and supporting the turntable during operation, reducing the possibility of positional displacement of the turntable during operation. The structure is simple and the operation is convenient.

[0013] Optionally, a bearing is provided on the support rod, and the outer cylindrical surface of the bearing abuts against the outer cylindrical surface of the guide groove.

[0014] By adopting the above technical solution, the bearing arrangement helps to reduce the friction between the support rod and the turntable, improves the smoothness of the turntable rotation, and reduces the possibility of the support rod being damaged by friction during long-term operation, which could affect the limiting effect.

[0015] Optionally, the tooling fixture includes a ring mold for fitting a ring and a rotating component for driving the ring mold to rotate. The rotating component is disposed on a turntable, and the ring mold is disposed on the rotating component and located on one side away from each other of the two sets of rotating components.

[0016] By adopting the above technical solution, and by symmetrically setting the ring molds on the side where the two pairs of rotating parts are far apart, the possibility of the other ring mold interfering with the operator's operation when the operator places the ring on one ring mold is reduced, making it more convenient for the operator to place the ring on the ring mold.

[0017] Optionally, two receiving grooves are provided on the upper surface of the turntable, and the receiving grooves correspond one-to-one with the ring mold and are located below the ring mold.

[0018] By adopting the above technical solution, some metal waste will be generated during the ring processing. The metal waste on the turntable will undergo centrifugal motion during the turntable rotation, which may cause it to scatter everywhere, making it difficult for operators to collect and process it later. At the same time, it may cause resource waste. The receiving tank can collect the metal waste generated during the processing, reduce the possibility of metal waste scattering everywhere, and make it convenient for operators to process the metal waste.

[0019] Optionally, two receiving boxes are detachably connected to the side wall of the turntable. The receiving boxes correspond one-to-one with the receiving troughs and are located below the receiving troughs. Two connecting ports are opened on the side wall of the turntable. The connecting ports correspond one-to-one with the receiving troughs and communicate with the cavity of the receiving troughs. The connecting ports are used to guide the scrap metal in the receiving troughs into the receiving boxes.

[0020] By adopting the above technical solution, the metal scrap collected in the receiving trough is introduced into the receiving box through the connecting port. The detachable design of the receiving box makes it easier for operators to take out the collected metal scrap for further processing.

[0021] Optionally, two horizontally arranged dovetail grooves are provided on the side wall of the turntable, and the dovetail grooves correspond one-to-one with the receiving boxes. The receiving boxes are provided with dovetail blocks, which are slidably connected to the dovetail grooves.

[0022] By adopting the above technical solution, when it is necessary to remove the receiving box from the turntable, the operator manually slides the receiving box. The movement of the receiving box drives the dovetail block to move. When the dovetail block disengages from the dovetail groove, the receiving box is disassembled, and the operator can pour out the metal scrap inside the receiving box. The structure is simple and the operation is convenient.

[0023] Optionally, a guiding slope is formed on the bottom wall of the receiving trough, and the guiding slope gradually decreases in height along the direction away from the connecting opening.

[0024] By adopting the above technical solution, the inclined guide surface can more smoothly guide the metal scrap in the receiving trough into the receiving box, reducing the possibility of metal scrap remaining in the receiving trough and requiring manual handling by the operator.

[0025] In summary, this application contains at least one of the following beneficial technical effects:

[0026] 1. During operation, the alternating movement of the two sets of tooling fixtures allows the turning tool to continuously turn the rings being processed, thereby improving work efficiency.

[0027] 2. The use of multiple support rods improves the stability of the turntable during processing, reducing the possibility of ring position displacement affecting processing accuracy.

[0028] 3. The receiving box can collect metal scrap generated during processing, reducing the possibility of metal scrap scattering everywhere. At the same time, the detachable connection of the receiving box to the turntable makes it more convenient for operators to handle metal scrap. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0036] This application discloses a high-efficiency ring engraving machine, referring to... Figure 1 as well as Figure 3 The device includes a frame 1, a tool holder 11 fixedly connected to the upper surface of the frame 1, an engraving device 7 for engraving rings on the tool holder 11, the engraving device 7 including an engraving knife 71 and a drive mechanism 72 for driving the engraving knife 71 to engrave rings, a rotating assembly 3 on the frame 1, the rotating assembly 3 including a rotating motor 31 and a connecting shaft 32, the rotating motor 31 fixedly connected to the upper surface of the frame 1 and the output shaft is vertically arranged, the connecting shaft 32 is coaxially fixedly connected to the output shaft of the rotating motor 31, and a horizontally arranged turntable 2 is fixedly connected to the connecting shaft 32, the center point of the turntable 2 is located directly above the connecting shaft 32.

[0037] Reference Figure 1 as well as Figure 3 The frame 1 is provided with a support assembly 5 for supporting the turntable 2. The support assembly 5 includes four support rods 51. A horizontally arranged guide groove 21 is opened on the lower surface of the turntable 2. The guide groove 21 is annular and coaxial with the connecting shaft 32. The four support rods 51 are circumferentially distributed in the guide groove 21 and are vertically arranged. The support rods 51 are fixedly connected to the upper surface of the frame 1 and the upper surface abuts against the inner top wall of the guide groove 21.

[0038] Reference Figure 1 as well as Figure 3 A bearing 52 is fixedly connected to the support rod 51. The bearing 52 is located in the guide groove 21 and the outer cylindrical surface of the bearing 52 abuts against the outer cylindrical surface of the guide groove 21. The upper surface of the support rod 51 is formed into a circular surface to reduce the possibility of friction damage to the support rod 51.

[0039] Reference Figure 1 as well as Figure 3 During operation, the rotation of the rotating motor 31 drives the connecting shaft 32 to rotate, and the rotation of the connecting shaft 32 drives the turntable 2 to rotate. During the rotation of the turntable 2, the support rod 51 always plays a supporting role, making the turntable 2 more stable. At the same time, the bearing 52 helps to reduce the friction between the support rod 51 and the turntable 2, making the turntable 2 rotate more smoothly.

[0040] Reference Figure 1 as well as Figure 2Two mounting seats 45 are fixedly connected to the upper surface of the turntable 2. The two mounting seats 45 are symmetrically arranged on the upper surface of the turntable 2. Each mounting seat 45 is provided with a tooling fixture 4 for holding the ring. The two sets of tooling fixtures 4 are symmetrically distributed. The tooling fixture 4 includes a ring mold 41 and a rotating component 42. The rotating component 42 is arranged on the upper surface of the mounting seat 45. The rotating component 42 includes a rotary motor 421. The rotary motor 421 is fixedly connected to the upper surface of the mounting seat 45 and its output shaft is horizontally arranged. The output shafts of the two rotary motors 421 are arranged facing each other. A vertically arranged connecting plate 47 is fixedly connected to the output shaft of the rotary motor 421. The ring mold 41 is arranged on the side wall of the two connecting plates 47 that are far apart from each other.

[0041] Reference Figure 3 as well as Figure 4 The ring mold 41 includes a mold sleeve 411, a drive block 412, a drive rod 413, a mounting cylinder 414, a drive bar 415, a slider 416, a mounting spring 417, and a drive bolt 418. The mounting cylinder 414 is fixedly connected to the side walls of two connecting plates 47 that are far apart from each other. A groove 419 is provided inside the mounting cylinder 414. The slider 416 is slidably disposed in the groove and the sliding direction is horizontal. The mounting spring 417 is located in the groove, and one end of the mounting spring 417 is connected to the slider 416. The other end of the mounting spring 416 is connected to the side wall of the groove away from the mold sleeve 411. The drive bolt 418 is threaded through the mounting cylinder 414 and is perpendicular to the sliding direction of the slider. A guide surface is provided on the side of the slider 416 away from the mounting spring 417. One end of the drive bolt 418 passes through... The slide groove 419 abuts against the guide surface on the slider 416. One end of the mounting cylinder 414 is fixedly connected to a vertically arranged support plate 48. The mold sleeve 411 is fixedly connected to the side walls of the two support plates 48 that are far apart from each other, and its axis is coaxial with the drive rod 413. Multiple expansion grooves 4411 communicating with the cavity are opened on the circumferential side wall of the mold sleeve 411. The expansion grooves 4411 form multiple expansion claws 4412 on the ring. The drive rod 413 is coaxially fixedly connected to the drive rod 415. The drive block 412 is fixedly connected to the side wall of the drive rod 413 that is far away from the drive rod 415 and is slidably connected inside the mold sleeve 411. The side wall of the drive block 412 abuts against the inner wall of the mold sleeve 411. The drive rod 415 is horizontally arranged and one end passes horizontally through the support plate 48 and is coaxially fixedly connected to the drive rod 413.

[0042] Reference Figure 2 as well as Figure 4After the operator places the ring on the expansion claw 4412, they tighten the drive bolt 418. The drive bolt 418 moves the slider 416, compressing the installation spring 417. The sliding of the slider 416 causes the drive rod 415 and drive rod 413 to move simultaneously. The gradual movement of the drive rod 413 causes the drive block 412 to gradually move closer to the support plate 48, causing the expansion claw 4412 to slowly open. The clamping force between the expansion claw 4412 and the ring will gradually increase, thus fixing the ring to the mold sleeve 411 by tightening. When the cutting tool 71 is cutting the ring, the rotary motor 421 is started. The rotation of the output shaft of the rotary motor 421 drives the mounting cylinder 414 to rotate. The rotation of the mounting cylinder 414 drives the support plate 48 to rotate. The rotation of the support plate 48 can drive the mold sleeve 411 to rotate.

[0043] Reference Figure 2 as well as Figure 3 During operation, the rotating motor 31 drives the turntable 2 to rotate. The rotation of the turntable 2 causes the two sets of tooling fixtures 4 to move to the bottom of the cutting tool 71, so that the cutting tool 71 can cut the ring to be processed more continuously, thereby improving work efficiency.

[0044] Reference Figure 2 as well as Figure 3 Two receiving grooves 22 are provided on the upper surface of the turntable 2. The receiving grooves 22 correspond one-to-one with the ring mold 41 and are located directly below the ring mold 41. An inclined guide slope 221 is formed on the inner bottom wall of the receiving groove 22. The two guide slopes 221 gradually increase in height as they approach each other. Two connecting ports 23 are provided on the side wall of the turntable 2. The connecting ports 23 correspond one-to-one with the receiving grooves 22 and are connected to the cavity of the receiving grooves 22. The connecting ports 23 are inclined and gradually increase in height as they approach the discharge end of the guide slope 221. Two inclined guide plates 24 are fixedly connected to the side wall of the turntable 2. The guide plates 24 correspond one-to-one with the connecting ports 23 and are located below the connecting ports 23. The guide plates 24 gradually increase in height as they approach the connecting ports 23.

[0045] Reference Figure 2 as well as Figure 3 Two horizontally arranged dovetail grooves 62 are provided on the side wall of the turntable 2. The dovetail grooves 62 correspond one-to-one with the guide plate 24. A dovetail block 61 is slidably connected in the dovetail groove 62. A receiving box 6 is fixedly connected to the side wall of the dovetail block 61 away from the bottom wall of the dovetail groove 62. The receiving box 6 is horizontally arranged and the opening is upward. The receiving box 6 is located below the guide plate 24.

[0046] The implementation principle of a high-efficiency ring engraving machine according to an embodiment of this application is as follows:

[0047] After the operator places the ring on the expansion claw 4412, he turns the drive bolt 418. The drive bolt 418 drives the slider 416 to move, and the installation spring 417 is compressed. The sliding of the slider 416 causes the drive rod 415 and the drive rod 413 to move simultaneously. The gradual movement of the drive rod 413 causes the drive block 412 to move gradually closer to the support plate 48, so that the expansion claw 4412 slowly expands and the clamping force between it and the ring gradually increases, thereby fixing the ring on the mold sleeve 411 by expansion.

[0048] The operator then starts the rotating motor 31. The rotation of the rotating motor 31 drives the turntable 2 to rotate, the rotation of the turntable 2 drives the mounting base 45 to rotate, and the rotation of the mounting base 45 drives the ring mold 41 to rotate, thereby moving the ring to be processed to the bottom of the cutting tool 71. The drive mechanism 72 drives the cutting tool 71 to cut the ring.

[0049] During operation, when one set of fixtures 4 moves to the underside of the cutting tool 71 to process the ring, the other set of fixtures 4 moves to the side of the rotating motor 31 away from the cutting tool 71. This allows the operator to disassemble the ring processed on the mold sleeve 411 from one side of the turntable 2 and install the next ring to be processed on the mold sleeve 411. The alternating movement of the two sets of fixtures 4 during operation allows the cutting tool 71 to process the rings more continuously, thereby improving work efficiency.

[0050] Metal scrap generated during ring processing falls into the receiving groove 22. Under the guidance of the guide slope 221, it moves through the connecting port 23 to the guide plate 24 and then falls into the receiving box 6 for collection. When the operator needs to remove the receiving box 6 from the turntable 2, the operator manually slides the receiving box 6. When the dovetail block 61 is disengaged from the dovetail groove 62, the receiving box 6 is disassembled, and the operator can pour out the metal scrap in the receiving box 6.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
