Description

Technical Field

[0001] This utility model relates to the field of jewelry processing equipment technology, and in particular to an upper clamping 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 chain loops. Each C-shaped chain loop has two weld points with its adjacent C-shaped chain loop, 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. The upper clamping mechanism is widely used to clamp and pull ropes or wires to achieve automated processing. This type of mechanism needs to have reliable clamping force and flexible rotation capabilities to adapt to different process requirements, such as adjusting the rope direction or performing winding operations. In existing technologies, upper clamping mechanisms often adopt a separate design, where the clamping and rotation actions are controlled by independent drive systems, such as using pneumatic or electric components to separately achieve the opening and closing of the clamps and the overall rotation. While this design can basically meet functional requirements, it suffers from problems such as complex structure, poor coordination, and insufficient control precision.

[0003] Specifically, traditional clamping mechanisms typically use simple lever or spring mechanisms to control the opening and closing of the clamps, while the rotation function is achieved through an additional motor or gear set, resulting in a large overall size and high manufacturing cost. Furthermore, because the drive sources for clamping and rotation are separate, asynchronous actions can easily occur during high-speed or precision operations, affecting clamping stability and efficiency. For example, during rotation, the clamping force may fluctuate due to drive delay, causing rope slippage or positional deviation.

[0004] Therefore, it is necessary to provide an upper clamping mechanism for an integrated real rope machine to overcome the above-mentioned defects. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] 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.

[0022] 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.

[0023] In an embodiment of this utility model, an upper clamping mechanism 100 for an integrated real rope machine is provided, which is used to clamp chain rings (C-shaped or circular) on the integrated real rope machine, drive the C-shaped chain rings to move to a predetermined position, and drive the C-shaped chain rings to rotate so as to perform functions such as twisting and welding at different angles.

[0024] like Figures 1-7 As shown, the upper clamping mechanism 100 for the integrated real rope machine includes: a fixing block 10, a sleeve 20, a clamping assembly 30, a rotation drive assembly 40, a top rod 50, a compression spring 60, and a linear drive assembly 70.

[0025] 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 vertically set up.

[0026] The sleeve 20 is inserted and fixed inside the through hole 101, and a rotating cylinder 21 is coaxially fixed thereto. The sleeve 20 and the rotating cylinder 21 can be partially sleeved together, and when the rotating cylinder 21 rotates, it can also drive the sleeve 20 to rotate synchronously. Both the sleeve 20 and the rotating cylinder 21 are inserted inside the through hole 101, and the ends of the two that are far apart from each other extend out of the through hole 101.

[0027] The rotating cylinder 21 has a through hole 201 coaxial with the through hole 101 inside, and a ring of spur gears 202 is provided at a predetermined position on the surface of the rotating cylinder 21. The length direction of each tooth profile of this ring of spur gears 202 is arranged along the axial direction of the rotating cylinder 21, and all the tooth profiles are arranged around the circumference of the rotating cylinder 21.

[0028] The rotation drive assembly 40 includes a rack 41 arranged perpendicularly to the rotating drum 21. The rack 41 has a row of straight teeth in its middle section that mesh with the spur gear 202. The rack 41 meshes with the spur gear 202, enabling the rack 41 to drive the rotating drum 21 to rotate circumferentially through its own linear motion. The direction of movement of the rack 41 corresponds to the direction of rotation of the rotating drum 21.

[0029] Specifically, the fixing block 10 is provided with a mounting plate 11. The mounting plate 11 is provided with a mounting block 12. The mounting block 12 has a guide hole 102 for the rack 41 to pass through. The portion of the rotating cylinder 21 with the spur gear 202 is located inside the sleeve 20. The sleeve 20 has a clearance hole 203, one side of the rack 41 passes through the guide hole 102, and the other side extends into the clearance hole 203 to mesh with the rotating cylinder 21 inside the sleeve 20. The central axis of the clearance hole 203 and the central axis of the guide hole 102 are on the same straight line.

[0030] Furthermore, the rotation drive assembly 40 also includes a first ring 42 located at a predetermined position on the fixed block 10, a second ring 43 located on the side of the rack 41 away from the guide hole 102, and a return spring 44 connecting the first ring 42 and the second ring 43. The return spring 44 and the rack 41 are located on opposite sides of the mounting plate 11. The return spring 44 is used to drive the rack 41 back to its initial state, that is, the return spring 44 pulls the rack 41 to one side by its own elastic force and maintains this state (defined as the initial state) to maintain the rotation angle of the rotating drum 21.

[0031] In one embodiment, a clamping assembly 30 is located at one end of a sleeve 20 and includes a pair of hinged clamps 31 and a tension spring 32, the tension spring 32 being used to force the pair of clamps 31 to open. Specifically, the clamping assembly 30 includes a pin 33 and a first connecting block 34 and a second connecting block 35 arranged side by side. The middle portions of the first connecting block 34 and the second connecting block 35 are hinged by the pin 33. It should be noted that the two connecting blocks are located on opposite sides of the pin 33, rather than being cross-hinged. The pair of clamps 31 are respectively located on the same side of the first connecting block 34 and the second connecting block 35. The two ends of the tension spring 32 are respectively connected to the sides of the first connecting block 34 and the second connecting block 35 away from the clamps 31. Therefore, when the tension spring 32 pulls the portions of the two connecting blocks away from the clamps 31 closer together, it forces the two clamps 31 to open, causing the two clamps 31 to switch to a clamping state. Correspondingly, when the parts of the two connecting blocks away from the clamp 31 are driven away from each other, the two clamps 31 will clamp each other.

[0032] Furthermore, such as Figure 5 As shown, the ends of the two clamps 31 furthest from the tension spring 32 have linearly extending arc-shaped grooves 301, meaning the cross-section of these grooves 301 is arc-shaped. The arc-shaped grooves 301 are used to position the wire. Figure 4 As shown, a limiting groove 302 is provided on one side of the clamp 31 near the other clamp 31, or the two clamps 31 are together arranged to form a limiting groove 302. This way, when the two clamps 31 clamp the chain ring and are subjected to external impact, the limiting groove 302 will prevent the chain ring from moving inward, thus ensuring the positioning accuracy of the chain ring during clamping.

[0033] In one embodiment, the push rod 50 passes through the through hole 201 of the rotating cylinder 21, and one end is tapered. This tapered end extends into a pair of clamps 31 (for example, the first connecting block 34 and the second connecting block 35) near the end of the tension spring 32, thereby forcing the tension spring 32 to be pulled, thus maintaining the clamps 31 in a clamped state. A circumferential protrusion 51 is provided at the end of the push rod 50 away from the clamping assembly 30. The protrusion 51 forms a shoulder structure relative to the surface of the push rod 50. A flange 52 is fixed to the end of the rotating cylinder 21 away from the clamping assembly 30. The circumferential side (i.e., the skirt) of the flange 52 abuts against one end of the rotating cylinder 21.

[0034] Specifically, a limiting ring 22 is provided on one side of the sleeve 20, which abuts against one end of the through hole 101 of the fixing block 10, preventing the sleeve 20 from moving in the direction of extending into the through hole 101. The skirt of the flange 52 is fixed to the end of the rotating cylinder 21 away from the clamping assembly 30, thus preventing the rotating cylinder 21 from moving in the direction of extending into the through hole 101. Combined with the fixed connection between the sleeve 20 and the rotating cylinder 21, the axial movement of the sleeve 20 and the rotating cylinder 21 within the through hole 101 is completely restricted, allowing only circumferential rotation. The through hole 201 penetrates the center of the flange 52, allowing one end of the push rod 50 to extend out of the flange 52.

[0035] Furthermore, the compression spring 60 is sleeved on the push rod 50, and its two ends abut against the protrusion 51 and the flange 52 respectively, so as to push the push rod 50 to press the clamping assembly 30, thereby closing the pair of clamps 31. That is, since the flange 52 is fixed to one end of the rotating cylinder 21, the compression spring 60 will push the push rod 50 to move in the direction close to the clamping assembly 30, so that the tapered end of the push rod 50 is kept in the state of extending between the two connecting blocks (34, 35). According to the above description, at this time, the two clamps 31 are in the closed state.

[0036] In one embodiment, the linear drive assembly 70 is used to drive the push rod 50 to move in a direction away from the clamping assembly 30.

[0037] Specifically, the fixing block 10 has an assembly block 13 on the side away from the clamping assembly 30. The end of the push rod 50 away from the clamping assembly 30 has a vertically positioned lifting piece 53. The lifting piece 53 can be a nut-washer structure screwed to one end of the push rod 50. The linear drive assembly 70 includes a hinge portion 71 and a first crank 72 and a second crank 73 both disposed on the hinge portion 71. The first crank 72 and the second crank 73 are arranged at a predetermined angle; in this embodiment, the first crank 72 and the second crank 73 are arranged perpendicularly.

[0038] Furthermore, there are two first cranks 72 arranged in parallel and spaced apart. The ends of the two first cranks 72 away from the hinge portion 71 are located between the flange 52 and the lifting plate 53, and are respectively located on both radial sides of the push rod 50. When the end of the second crank 73 away from the hinge portion 71 is pushed inward by other driving devices, the end of the first crank 72 away from the hinge portion 71 lifts the lifting plate 53, compresses the compression spring 60, thereby causing the push rod 50 to move in a direction away from the clamping assembly 30, releasing the expansion action of the push rod 50 on the tension spring 32. At this time, the tension action of the tension spring 32 causes the two clamps 31 to open.

[0039] Furthermore, a roller 74 is provided at the end of the second crank 73 away from the hinge 71, so that when an external mechanism (such as a mechanism that strikes the crank) drives one end of the second crank 73, sliding friction will not be formed, thus reducing driving resistance.

[0040] Furthermore, the push rod 50 is also fitted with a buffer plate 54. The buffer plate 54 is attached to the side of the lifting plate 53 near the flange 52. Therefore, the buffer plate 54 can provide a buffering effect before one end of the first crank 72 touches and presses against the lifting plate 53.

[0041] In summary, the upper clamping mechanism 100 for an integrated rope machine provided by this utility model utilizes the synergistic effect of the linear drive component 70 and the rotary drive component 40 to achieve automatic opening and closing and circumferential rotation of the clamping component 30, thereby simplifying the mechanism layout and improving control precision and operational efficiency. Specifically, the linear drive component 70 drives the top rod 50 to move, and controls the closing and opening of the clamp 31 through the cooperation of the compression spring 60 and the conical end of the top rod 50; simultaneously, the rotary drive component 40 meshes with the spur gear 202 on the rotating drum 21 through the rack 41, driving the rotating drum 21 and the clamping component 30 to rotate as a whole. This integrated design not only reduces the use of independent components, but also ensures the synchronization of clamping and rotation actions, ultimately improving the reliability and adaptability of the equipment.

[0042] 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.
