Description

Technical Field

[0001] The utility model relates to the technical field of chain bead hole processing equipment, in particular to a chain bead hole processing equipment. Background Art

[0002] During the operation of traditional gold jewelry hole-making devices, mechanical impact, laser cutting or water jet cutting are often used to achieve precise hole-making on gold jewelry. Although these technologies have guaranteed accuracy and efficiency, they all face the problem of lacking an effective collection mechanism for the gold flakes produced after hole-making. These residual materials often splash around under the action of high-speed cutting or impact force, which not only pollutes the working environment and increases cleaning costs, but more importantly, the loss of a large amount of metal residual materials directly leads to unnecessary waste of raw materials. For the gold jewelry processing industry that uses precious metals such as gold as raw materials, this is undoubtedly a considerable economic loss. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Combine the following Figures 1 to 6 , describing a chain bead hole processing equipment according to an embodiment of the utility model.

[0044] A bead hole processing device, comprising a base plate 41, a base plate movable module 42, a drilling module 43, a gold sheet taking-out module 44, a three-claw tool 45 and a screw thread needle 46;

[0045] The mounting end of the bottom plate movable module 42 is mounted on the frame, the movable end of the bottom plate movable module 42 is fixedly connected to the bottom plate 41, and the frame is slidably connected to the bottom plate 41;

[0046] The drilling module 43 and the gold sheet bringing out module 44 are both located at the top of the base plate 41, the movable end of the drilling module 43 is connected to the three-claw tool 45, and the movable end of the gold sheet bringing out module 44 is connected to the screw thread needle 46, the tip of the screw thread needle 46 is penetrated inside the three-claw tool 45, the drilling module 43 is used to drive the three-claw tool 45 to rotate and expand or contract outward, the three-claw tool 45 is used to drill holes in the gold beads, the gold sheet bringing out module 44 is used to drive the screw thread needle 46 to rotate and move back and forth, and the screw thread needle 46 is used to bring out the gold sheets inside the gold beads.

[0047] The bead hole processing device 4 integrates the functions of the drilling module 43 and the gold flake removal module 44, thereby realizing efficient drilling of gold beads and subsequent accurate separation and removal of gold flakes. The drilling module 43 drives the three-claw tool 45 to rotate and expand outward, ensuring that the drilling process is fast and accurate; while the gold flake removal module 44 utilizes the rotation and forward and backward movement of the screw thread needle 46 to effectively separate and remove the loose gold flakes from the gold beads after drilling, greatly improving production efficiency.

[0048] The precise coordination between the three-jaw tool 45 and the thread needle 46 ensures the accuracy and consistency of the drilling and gold sheet separation processes. The outward expansion force of the three-jaw tool 45 can act evenly on the surface of the gold beads, avoiding deviation or deformation during drilling; while the rotation of the thread needle 46 can penetrate into the gap between the gold sheet and the gold beads, further promoting the separation of the gold sheet, thereby improving the processing accuracy and product quality.

[0049] The drilling module 43 includes a tool driving component 431, a tool expansion component 432, and a tool rotation component 433;

[0050] The driving end of the tool driving component 431 is connected to the tool expansion component 432. The tool driving component 431 is used to provide a power source for the tool expansion component 432. The tool expansion component 432 is used to drive the three-jaw tool 45 to expand or contract. The tool rotation component 433 is used to drive the three-jaw tool 45 to rotate.

[0051] When the three-jaw tool 45 rotates under the action of the tool rotation component 433, the tip of the three-jaw tool 45 continuously contacts the surface of the gold beads and applies a cutting force. At the same time, the three-jaw tool 45 moves forward under the action of the tool driving component 431, so that the cutting edge can gradually penetrate into the gold beads to form continuous holes.

[0052] The drilling module 43 realizes precise control of the three-jaw tool 45 by integrating the tool driving component 431, the tool expansion component 432, and the tool rotation component 433. The tool driving component 431 provides a stable and reliable power source for the tool expansion component 432, ensuring the accuracy of tool expansion or contraction; while the tool rotation component 433 drives the three-jaw tool 45 to rotate at a set speed, ensuring the smoothness and efficiency of the drilling process, and reducing errors and scrap rates caused by improper operation.

[0053] The tool rotation component 433 includes a rotating sleeve 4331, a first tool rotation gear 4332, a second tool rotation gear 4333, a tool rotation chain, and a tool rotation driving part 4334;

[0054] The rotating sleeve 4331 is rotatably installed on the bottom plate 41. The length direction of the rotating sleeve 4331 is the front-back direction. The end of the rotating sleeve 4331 is connected to the three-jaw tool 45. The tool rotation driving part 4334 is installed on the bottom plate 41. The output end of the tool rotation driving part 4334 is fixedly connected to the first tool rotation gear 4332. The second tool rotation gear 4333 is fixedly sleeved on the end of the rotating sleeve 4331 away from the three-jaw tool 45. The tool rotation chain is sleeved on the first tool rotation gear 4332 and the second tool rotation gear 4333.

[0055] It should be noted that the tool rotation driving member 4334 is preferably a motor. When the tool rotation driving member 4334 is started, it can drive the first tool rotation gear 4332 to rotate. The first tool rotation gear 4332 can drive the second tool rotation gear 4333 and the tool rotation chain to rotate. The second tool rotation gear 4333 can drive the rotation sleeve 4331 to rotate, so that the rotation sleeve 4331 can drive the three-jaw tool 45 to rotate.

[0056] In addition, a splash guard is provided at the end of the rotation sleeve 4331 close to the three-jaw tool 45. The splash guard is annularly installed outside the three-jaw tool 45. When the three-jaw tool 45 starts drilling, it can prevent the fragments on the gold beads from splashing outwards and effectively collect the metal fragments.

[0057] The tool expansion assembly 432 includes a tool expansion slider 4321, a tool expansion guide block 4322 and a tool expansion sleeve 4323. A plurality of tool chutes are provided on one side of the rotation sleeve 4331 close to the three-jaw tool 45. The plurality of tool expansion sliders 4321 are respectively slidably connected to the plurality of tool chutes in a one-to-one correspondence, and the tool expansion slider 4321 is fixedly connected to the three-jaw tool 45;

[0058] One end of the tool expansion sleeve 4323 close to the three-jaw tool 45 movably passes through the inside of the rotation sleeve 4331. The end of the tool expansion sleeve 4323 is threadedly connected with the tool expansion guide block 4322. One end of the tool expansion guide block 4322 close to the tool expansion sleeve 4323 movably passes through the inside of the rotation sleeve 4331;

[0059] The tool expansion slider 4321 is provided with an inclined expansion slide rail 4324. The tool expansion guide block 4322 is respectively slidably connected to the plurality of expansion slide rails 4324. The driving end of the tool driving assembly 431 is connected to the tool expansion sleeve 4323. The tool driving assembly 431 is used to drive the tool expansion sleeve 4323 and the tool expansion guide block 4322 to move back and forth. The tool expansion guide block 4322 is used to guide the plurality of tool expansion sliders 4321 to move back and forth on the tool chute;

[0060] The expansion slide rail 4324 is inclined towards the bottom from front to back. The tool expansion guide block 4322 is provided with an inclined surface, and the inclined surface is inclined towards the bottom from front to back.

[0061] The tool drive assembly 431 is activated. The tool drive assembly 431 can drive the tool expansion sleeve 4323 to move forward, and the tool expansion sleeve 4323 drives the tool expansion guide block 4322 to move forward. Since the tool expansion guide block 4322 is provided with an inclined surface, and multiple expansion slide rails 4324 are all slidably connected to the tool expansion guide block 4322, the multiple tool expansion sliders 4321 move outward under the guidance of the inclined surface, thereby ensuring that the three-jaw tool 45 expands outward, so as to drill holes in the surface of the gold beads.

[0062] Similarly, when the tool drive assembly 431 drives the tool expansion sleeve 4323 to move backward, the multiple tool expansion sliders 4321 move inward under the guidance of the tool expansion guide block 4322, thereby contracting the three-jaw tool 45 and completing the drilling process.

[0063] Among them, by adjusting the movement range of the tool expansion sleeve 4323, the expansion range of the three-jaw tool 45 can be changed, so as to adapt to the processing requirements of workpieces with different diameters.

[0064] In addition, the tool expansion slider 4321 is slidably connected to the tool chute, which can ensure the stable clamping of the three-jaw tool 45 when it rotates at high speed or bears a large cutting force, effectively preventing the three-jaw tool 45 from loosening or shifting, thereby improving the processing accuracy and the quality of the finished product.

[0065] The tool drive assembly 431 includes a tool movement drive 4311, a tool drive slider 4312 and a tool drive slide rail 4313;

[0066] The tool drive slide rail 4313 is horizontally installed on the bottom plate 41. The length direction of the tool drive slide rail 4313 is the front-back direction. The tool drive slider 4312 is slidably connected to the tool drive slide rail 4313, and the tool drive slider 4312 is connected to the tool expansion sleeve 4323;

[0067] The tool movement drive 4311 is installed on the bottom plate 41, and the output end of the tool movement drive 4311 is fixedly connected to the tool drive slider 4312.

[0068] It should be noted that the tool movement drive 4311 is preferably a cylinder. When the tool movement drive 4311 is activated, the tool movement drive 4311 drives the tool drive slider 4312 to move on the tool drive slide rail 4313, so that the tool drive slider 4312 can drive the tool expansion sleeve 4323 to move in the front-back direction, thereby ensuring that the tool expansion sleeve 4323 can drive the three-jaw tool 45 to expand or contract.

[0069] Among them, the structure of the tool driving component 431 enables the driving force to be transmitted to the tool expansion sleeve 4323 quickly and fully, which can effectively reduce the complexity of the transmission chain and energy loss.

[0070] The gold sheet taking-out module 44 includes a thimble driving component 441, a thimble rotating component 442, and a buffer component 443. The thimble driving component 441 is used to drive the thread thimble 46 to move back and forth, the thimble rotating component 442 is used to drive the thread thimble 46 to rotate, and the buffer component 443 is used to reduce the forward impact force of the thread thimble 46.

[0071] The thimble driving component 441 can accurately control the forward and backward movement of the thread thimble 46 at the right time and speed. At the same time, the thimble rotating component 442 can drive the thread thimble 46 to rotate. The rotation action of the thread thimble 46 effectively breaks the adsorption force or bonding force between the gold sheet and the gold bead, enabling the gold sheet to be completely and smoothly separated, thereby improving the quality and usability of the gold sheet.

[0072] The buffer component 443 can effectively relieve the impact force that may be generated during the forward movement of the thread thimble 46, and also reduce the risk of damage to the gold sheet caused by excessive impact force, ensuring the integrity and high quality of the gold sheet.

[0073] The thimble driving component 441 includes a thimble movement driving part 4411, a thimble driving slider 4412, and a thimble driving slide rail 4413. The thimble driving slide rail 4413 is horizontally installed on the bottom plate 41. The length direction of the thimble driving slide rail 4413 is the front-back direction. The thimble driving slider 4412 is slidably connected to the thimble driving slide rail 4413. The thimble rotating component 442 and the buffer component 443 are both installed on the thimble driving slider 4412.

[0074] It should be noted that the thimble movement driving part 4411 is a cylinder. When the thimble movement driving part 4411 is started, the thimble movement driving part 4411 drives the thimble driving slider 4412 to move on the thimble driving slide rail 4413, so that the thimble driving slider 4412 can drive the thread thimble 46 to move in the front-back direction.

[0075] Among them, the thimble rotating component 442 and the buffer component 443 are both located on the thimble driving slider 4412, which can ensure that the thimble rotating component 442 and the buffer component 443 can move forward or backward simultaneously with the thread thimble 46. So that when the thread thimble 46 advances, the thimble rotating component 442 can drive the thread thimble 46 to rotate at the same time. Moreover, when the tip of the thread thimble 46 extends into the gold bead, the buffer component 443 can reduce and disperse the forward impact force of the thread thimble 46, making the forward movement of the thread thimble 46 smoother and more controllable.

[0076] Moreover, by controlling the movement range of the ejector pin to drive the slider 4412, the movement range of the thread needle 46 is defined, thereby improving the stability and accuracy of the thread needle 46 when pushing the gold sheet, and avoiding problems such as gold sheet damage or incomplete separation caused by position deviation or uneven force.

[0077] The ejector pin rotation assembly 442 includes an ejector pin rotation driving member 4421, a first ejector pin rotation gear 4422, a second ejector pin rotation gear 4423, an ejector pin rotation sleeve 4424, and an ejector pin rotation chain;

[0078] The end of the thread needle 46 away from the three-jaw cutter 45 is fixedly connected to the ejector pin rotation sleeve 4424. The ejector pin rotation sleeve 4424 is rotatably installed on the top of the first ejector pin driving slider 4412. The outer wall of the ejector pin rotation sleeve 4424 is fixedly sleeved with the second ejector pin rotation gear 4423. The ejector pin rotation driving member 4421 is installed on the ejector pin driving slider 4412. The driving end of the ejector pin rotation driving member 4421 is fixedly sleeved with the first ejector pin rotation gear 4422. The ejector pin rotation chain is sleeved on the first ejector pin rotation gear 4422 and the second ejector pin rotation gear 4423;

[0079] The end of the thread needle 46 away from the ejector pin rotation sleeve 4424 movably penetrates through the inside of the cutter expansion sleeve 4323, the cutter expansion guide block 4322, and the three-jaw cutter 45.

[0080] It should be noted that the ejector pin rotation driving member 4421 is preferably a motor. When the ejector pin rotation driving member 4421 is started, the ejector pin rotation driving member 4421 drives the first ejector pin rotation gear 4422 to rotate. The first ejector pin rotation gear 4422 drives the second ejector pin rotation gear 4423 and the ejector pin rotation chain to rotate, so that the second ejector pin rotation gear 4423 can drive the ejector pin rotation sleeve 4424 to rotate, and the ejector pin rotation sleeve 4424 drives the thread needle 46 to rotate. This transmission method not only has high transmission efficiency, but also runs smoothly, reducing power loss and vibration, and reducing the occurrence of gold sheet damage caused by position deviation of the thread needle 46.

[0081] In addition, in this solution, it is defined that the end of the thread needle 46 is located inside the three-jaw cutter 45, which can position the position of the thread needle 46, ensure that the thread needle 46 rotates forward, overcome the bonding force between the gold sheet and the gold bead, and stably and effectively separate the gold sheet from the gold bead.

[0082] Moreover, the screw needle 46 is sequentially inserted into the interior of the tool expansion sleeve 4323 and the tool expansion guide block 4322, which can reduce the floor space occupied and facilitate the integration and coordinated work with the ejector drive assembly 441, the buffer assembly 443 and other structures, thereby improving the integration and working efficiency of the entire gold sheet bringing out module 44.

[0083] The buffer assembly 443 includes a buffer spring 4431 and a buffer block 4432. The buffer block 4432 is rotatably mounted on the ejector rotating sleeve 4424. One end of the buffer spring 4431 abuts against the ejector driving slider 4412, and the other end of the buffer spring 4431 abuts against the buffer block 4432. The buffer block 4432 is movably abutted against the tool expansion sleeve 4323.

[0084] Under the action of the ejector drive assembly 441, the screw thread needle 46 and the ejector rotating sleeve 4424 move forward, and the buffer block 4432 first contacts the tool expansion sleeve 4323. At this time, the ejector rotating sleeve 4424 continues to move forward, causing the buffer spring 4431 sleeved on the ejector rotating sleeve 4424 to deform, and the elastic deformation of the buffer spring 4431 absorbs and disperses the impact force, making the forward movement of the screw thread needle 46 more stable and controllable. When the screw thread needle 46 encounters resistance or needs to adjust its position, the elasticity of the buffer spring 4431 can provide a flexible support and adjustment space, thereby reducing the vibration and instability factors caused by sudden stop or reverse movement.

[0085] The frame is provided with a bottom plate movable slide rail 421 at the bottom of the bottom plate 41, and the length direction of the bottom plate movable slide rail 421 is the front-to-back direction. The bottom of the bottom plate 41 is provided with a first bottom plate movable slider 422, and the first bottom plate movable slider 422 is slidably connected to the bottom plate movable slide rail 421. The movable end of the bottom plate movable module 42 is fixedly connected to the bottom of the bottom plate 41, and the bottom plate movable module 42 is used to drive the first bottom plate movable slider 422 to move on the bottom plate movable slide rail 421.

[0086] Since the rotating sleeve 4331 is rotatably installed on the base plate 41, the base plate movable module 42 can not only adjust the front and rear positions of the base plate 41, but also adjust the front and rear positions of the rotating sleeve 4331 and the three-claw tool 45, so that the three-claw tool 45 can be close to the surface of the gold bead, ensuring that the three-claw tool 45 can drill the gold bead.

[0087] In addition, through the cooperation between the first bottom plate movable slider 422 and the bottom plate movable slide rail 421, the movable range of the bottom plate 41 can be accurately controlled to prevent the three-claw tool 45 from shaking during the forward movement.

[0088] The bottom plate movable module 42 includes a bottom plate movable screw rod 423, a second bottom plate movable slider 424, a bottom plate movable driving member 425, a first bottom plate movable gear 426, a second bottom plate movable gear 427 and a bottom plate movable chain;

[0089] The bottom plate movable screw rod 423 is transmission-mounted on the frame, the length direction of the bottom plate movable screw rod 423 is consistent with the length direction of the bottom plate movable slide rail 421, the bottom plate movable screw rod 423 is threadedly connected with a second bottom plate movable slide block 424, and the second bottom plate movable slide block 424 is fixedly connected to the bottom of the bottom plate 41;

[0090] The bottom plate movable driving member 425 is installed on the frame, and the output end of the bottom plate movable driving member 425 is fixedly connected to the first bottom plate movable gear 426, and the end of the bottom plate movable screw rod 423 close to the first bottom plate movable gear 426 is fixedly sleeved with the second bottom plate movable gear 427, and the bottom plate movable chain is sleeved on the first bottom plate movable gear 426 and the second bottom plate movable gear 427.

[0091] It is worth noting that the bottom plate movable driving member 425 is preferably a motor. When the bottom plate movable driving member 425 is started, it can drive the first bottom plate movable gear 426 to rotate, and the rotation of the first bottom plate movable gear 426 can drive the second bottom plate movable gear 427 and the bottom plate movable chain to rotate, and the second bottom plate movable gear 427 can drive the bottom plate movable screw rod 423 to rotate. The rotation of the bottom plate movable screw rod 423 can drive the second bottom plate movable slider 424 to move back and forth on the bottom plate movable screw rod 423, thereby driving the bottom plate 41 to move in the front-back direction.

[0092] Moreover, the screw drive has a self-locking characteristic, which can effectively prevent the base plate 41 from accidentally moving when not acted upon by external forces, thereby improving the safety and reliability of the entire system.

[0093] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
