Description

Technical Field

[0001] This utility model relates to the field of jewelry processing equipment technology, and in particular to a hanging ring mechanism for an integrated real rope machine. Background Technology

[0002] A true rope chain is a chain formed by the interlocking and welding of multiple C-shaped links. Each C-shaped link has two weld points with its adjacent link, resulting in high connection strength. It is widely used in jewelry making. A true rope machine is a device that processes metal wire into true rope chains. Its hanging mechanism, as one of its core components, is mainly responsible for flipping the links held laterally by the lower clamping mechanism during processing. This hooks the unwelded links onto the links in the rope chain, facilitating subsequent welding of adjacent links.

[0003] In existing technologies, the chain loop hanging mechanism typically employs a separate drive design, such as using independent rotary motors and clamping cylinders to control the movements of the turntable and grippers respectively, to achieve chain loop gripping and attachment. While this design can accomplish basic functions, it suffers from problems such as complex structure, large space occupation, and numerous transmission links, leading to difficulties in coordinated control, susceptibility to chain loop position deviations, and high maintenance costs. Furthermore, because the drive sources for rotation and clamping are separate, timing asynchrony can easily occur during high-speed production, causing the chain loops to be loosely attached or fall off, affecting the overall production rhythm and yield rate. Therefore, it is necessary to provide a chain loop hanging mechanism for integrated real rope machines to overcome the aforementioned shortcomings. Utility Model Content

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0020] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0021] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0022] In an embodiment of this utility model, a hanging ring mechanism 100 for an integrated real rope machine is provided, which is used to flip the C-shaped chain ring held laterally by the lower clamping mechanism during the processing, thereby hooking the unwelded chain ring onto the chain ring in the rope chain, so as to carry out subsequent welding of adjacent chain rings.

[0023] like Figures 1-7 As shown, the hanging ring mechanism 100 for the integrated real rope machine includes: a fixing block 10, a rotating drum 20, a clamping assembly 30, a drive rod 40, a first drive device 50, a drive rack 60, and a second drive device (not shown in the figure).

[0024] The fixing block 10 is used to fix the machine frame of the integrated real rope machine at a preset position, serving as a fixing carrier for other components. The fixing block 10 has a cylindrical through hole 101, which can be set horizontally or vertically.

[0025] The rotating drum 20 is fixed inside the through hole 101, allowing it to rotate circumferentially relative to the through hole 101. A through hole 201, coaxial with the through hole 101, is provided inside the rotating drum 20, through which the drive rod 40 passes. A ring of spur gears 21 is positioned at a predetermined location on the surface of the rotating drum 20. Specifically, the spur gears 21 can be machined on the surface of the rotating drum 20 to obtain a gear structure with a circular cross-section, where each tooth profile is elongated.

[0026] A clamping assembly 30 is located at one end of the rotating drum 20 and includes an openable abutment block 31 and a deflecting block 32. The abutment block 31 abuts against one side of the chain ring, and the deflecting block 32 deflects the other side of the chain ring to hook it onto the rope chain. Specifically, the chain ring at the end of the real rope chain is fixed, and the C-shaped chain ring to be hooked is brought close to the chain ring of the real rope chain. The deflecting block 32 deflects the chain ring to be hooked from the side, so that the opening of the C-shaped chain ring passes through the chain ring of the real rope chain, and the two chain rings form a cross-interlocking structure. Then, the C-shaped chain ring is welded to the chain ring of the real rope chain by a laser welding mechanism.

[0027] Specifically, the clamping assembly 30 includes a mounting block 33 fixed to one end of the rotating drum 20, a mounting rod 34 disposed on the mounting block 33, and a hinge rod 35 hinged to the mounting block 33. The middle portion of the hinge rod 35 is hinged to the mounting block 33. An abutment block 31 is fixed to one end of the mounting rod 34, and a moving block 32 abuts against one end of the hinge rod 35. The drive rod 40 is used to move the moving block 32 closer to the abutment block 31 by expanding the distance between the end of the mounting rod 34 away from the abutment block 31 and the end of the hinge rod 35 away from the moving block 32.

[0028] The hinge rod 35 has a first fixing rod 36 on the side away from the actuating block 32, and the mounting block 33 has a second fixing rod 37. A first tension spring 38 is provided between the first fixing rod 36 and the second fixing rod 37. The first tension spring 38 is used to force the actuating block 32 to open with the abutment block 31, thereby maintaining the actuating block 32 and the abutment block 31 in a close position.

[0029] In one embodiment, the abutment block 31 includes a strip 311 connected to the mounting rod 34 and an abutment rod 312 disposed at one end of the strip 311. The end edge of the strip 311 near the abutment rod 312 has an abutment slope 313 with the middle of the abutment rod 312. The actuating block 32 includes a strip block 321 connected to the hinge rod 35, a tapered block 322 disposed at the end of the tapered block 321 away from the hinge rod 35 and inclined toward the abutment block 31, and a lever 323 disposed at the end of the tapered block 322 away from the tapered block 321. The lever 323 is arranged parallel to the tapered block 321. When the abutment block 31 and the actuating block 32 approach each other to their maximum stroke, the abutment slope 313 is parallel to the edge of the tapered block 322, and the abutment rod 312 is parallel to the lever 323. Furthermore, a protrusion 324 is vertically provided on one side of the lever 323, and the protrusion 324 and the end of the lever 323 are connected by an arc. When the abutment block 31 and the actuating block 32 approach each other to the maximum stroke, the protrusion 324 and the abutment rod 312 are on the same straight line.

[0030] In an embodiment of this utility model, the drive rod 40 passes through the through hole 201 and is used to close the clamping assembly 30 after being driven axially. The first drive device 50 is used to drive the drive rod 40 to move axially. The first drive device 50 can be a cylinder (the thrust can be set to be relatively small, so that no large stress is generated during driving).

[0031] Specifically, the drive rod 40 has a contraction portion 41 and an expansion portion 42 at the end near the clamping assembly 30. The thickness of the expansion portion 42 is greater than the thickness of the contraction portion 41, and both are flat on the side near the hinge rod 35 with a beveled transition at the connection point. When the contraction portion 41 is located between the mounting rod 34 and the hinge rod 35, the first tension spring 38 pulls the mounting rod 34 and the hinge rod 35, causing the abutment block 31 and the actuating block 32 to open; when the expansion portion 42 is located between the mounting rod 34 and the hinge rod 35, the first tension spring 38 is stretched, and the abutment block 31 and the actuating block 32 open.

[0032] In one embodiment, a washer 43 is vertically disposed on the side of the drive rod 40 away from the clamping assembly 30. A first crank 11 and a second crank 12 are hinged to a predetermined position on the fixing block 10. In each crank, the line connecting its two ends relative to the hinge position is approximately right-angled. The first crank 11 and the second crank 12 are respectively disposed on opposite axial sides of the washer 43. The first drive device 50 is used to push one end of the first crank 11, causing the other end to abut against the washer 43 and push the drive rod 40 axially towards the clamping assembly 30. During this process, the first crank 11 rotates in the forward direction, while the second crank 12 is driven to rotate in the reverse direction by the washer 43. When the drive rod 40 moves to its maximum stroke, one end of the second crank 12 abuts against a predetermined position on the fixing block 10, thereby limiting the movement of the washer 43 and achieving precise control of the stroke of the drive rod 40.

[0033] Furthermore, the inner wall of the perforation 201 is provided with a receiving groove 202. The diameter of the receiving groove 202 is larger than the diameter of the perforation 201, and the opening faces the first driving device 50. The driving rod 40 is provided with a convex ring 44 that can move axially in the receiving groove 202. The driving rod 40 is fitted with a compression spring 45 at both ends, which respectively abuts between the convex ring 44 and the bottom of the receiving groove 202. The compression spring 45 is used to force the driving rod 40 to move away from the clamping assembly 30, that is, when the first driving device 50 does not apply pressure to the first crank 11, the compression spring 45 causes the retracted portion 41 of the driving rod 40 to be located between the mounting rod 34 and the hinge rod 35.

[0034] In one embodiment, the drive rack 60 is arranged perpendicularly to the rotating drum 20 and meshes with the spur gear 21, so that when the drive rack 60 is linearly driven, it drives the rotating drum 20 to rotate circumferentially. A second drive device (not shown in the figure) is used to drive the drive rack 60 to move axially. It should be noted that the second drive device can be a cam crank, cylinder, motor, or other mechanism or device, which will not be described in detail here.

[0035] The drive rack 60 has a third fixing rod 61 at one end and a fourth fixing rod 62 at a preset position on the fixing block 10. A second tension spring 63 is provided between the third fixing rod 61 and the fourth fixing rod 62. The second tension spring 63 is used to force the drive rack 60 to reset to the state before it was driven by the second driving device. That is, the reset action of the drive rack 60 is realized through a simple structure.

[0036] In summary, the hanging ring mechanism 100 for an integrated real rope machine provided by this utility model utilizes the meshing of a drive rack 60 with a spur gear 21 on the surface of the rotating drum 20. Under the linear drive of the second drive device, the rotating drum 20 is rotated circumferentially, thereby adjusting the position of the clamping assembly 30 to align with the chain ring. Simultaneously, the drive rod 40, which passes through the through hole 201 of the rotating drum 20, is axially driven by the first drive device 50, causing the abutment block 31 and the actuating block 32 in the clamping assembly 30 to close, thereby reliably gripping the chain ring and hooking it onto the rope chain. This utility model concentrates the rotation and clamping functions in the rotating drum structure, reducing external transmission components and simplifying the mechanism layout; it improves the accuracy and consistency of the hanging ring position and reduces the failure rate; the modular design reduces space occupation and facilitates installation and maintenance; at the same time, the independent control of the dual drive devices ensures the coordination of the action sequence, improving production efficiency and product stability.

[0037] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
