Description

Technical Field

[0001] This application relates to the field of fixtures, and more particularly to a silver medal tooling fixture. Background Technology

[0002] In the field of metal processing, silver medals, as exquisite and valuable handicrafts or medals, have extremely high requirements for precision and quality in their manufacturing process. Silver medal fixtures, as key equipment in the processing, are mainly used to fix and support the silver medals to ensure their stability and positioning accuracy during processing (such as stamping and engraving). Traditional silver medal fixtures generally use rigid jaws combined with pneumatic drives for gripping. However, in high-frequency operations, excessive jaw opening can lead to two major problems: firstly, the connection structure at the base of the jaws bears repeated impact loads, easily causing metal fatigue cracks; secondly, during the jaw closing process, if the silver medal is too small, the lack of precise force control for small silver medals can easily cause surface damage due to excessive force, such as scratches and dents, seriously affecting the yield and market value of the silver medals.

[0034] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0036] Embodiments of this application provide a silver medal tooling fixture, comprising:

[0037] First gripper;

[0038] The second gripper is positioned directly opposite the first gripper.

[0039] A driving assembly, wherein one end of both the first gripper and the second gripper is disposed on the driving assembly;

[0040] A buffer assembly includes a first buffer, a second buffer, and a connecting elastic member. The first buffer and the second buffer are arranged facing each other. The first buffer is disposed on the first gripper, and the second buffer is disposed on the second gripper. The connecting elastic member is parallel to the first buffer and the second buffer, and one end of the connecting elastic member is disposed on the first gripper and the other end is disposed on the second gripper.

[0041] When the driving component drives the first gripper and the second gripper to close, the first buffer and the second buffer can abut against each other.

[0042] The aforementioned silver medal fixture features a structure comprising a first jaw, a second jaw, a drive assembly, and a buffer assembly. The first and second jaws are positioned opposite each other, and the drive assembly controls their opening and closing. The buffer assembly includes a first buffer element, a second buffer element, and a connecting elastic element, arranged parallel between the jaws. When the drive assembly opens the jaws to a certain extent, the connecting elastic element prevents metal fatigue cracks caused by repeated impacts on the jaw root connection structure. Simultaneously, the connecting elastic element provides necessary buffering and resetting force when the jaws reset, ensuring the stability of the jaw opening and closing accuracy. When the drive assembly closes the jaws, the first and second buffer elements abut against each other, effectively limiting excessive jaw closure and preventing excessive clamping force that could damage the silver medal.

[0043] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] according to Figure 1 - Figure 4 This application provides a silver medal tooling fixture 100, including: a first gripper 10, a second gripper 20, a drive assembly 30 and a buffer assembly 40.

[0045] The first gripper 20 is positioned opposite to the first gripper 10. A drive assembly 30 is included, with one end of both the first gripper 10 and the second gripper 20 mounted on it. A buffer assembly 40 includes a first buffer 41, a second buffer 42, and a connecting elastic member 43. The first buffer 41 and the second buffer 42 are positioned opposite each other, with the first buffer 41 mounted on the first gripper 10 and the second buffer 42 mounted on the second gripper 20. The connecting elastic member 43 is parallel to the first buffer 41 and the second buffer 42, with one end mounted on the first gripper 10 and the other end mounted on the second gripper 20. When the drive assembly 30 drives the first gripper 10 and the second gripper 20 to close, the first buffer 41 and the second buffer 42 can abut against each other.

[0046] Specifically, the first gripper 10 and the second gripper 20, as the main components for directly gripping the silver medal, are positioned opposite each other and work together to achieve a stable grip on the medal. The drive assembly 30 provides power for the opening and closing of the first gripper 10 and the second gripper 20. When the grippers close to a certain extent, the first buffer 41 and the second buffer 42 abut against each other, limiting the grippers from closing too much and effectively preventing damage to the surface of the silver medal, such as scratches or dents, due to excessive force. The connecting elastic element 43 is arranged parallel to the first buffer 41 and the second buffer 42. The connecting elastic element 43 provides additional buffering and restoring force for the opening and closing of the grippers, preventing the root connection structure of the grippers from bearing excessive impact load due to excessive opening, reducing the generation of metal fatigue cracks, extending the service life of the fixture, ensuring that the first gripper 10 and the second gripper 20 can accurately return to their initial positions during the return stroke, avoiding cumulative deviations in opening and closing accuracy, and improving processing accuracy.

[0047] Furthermore, the connecting elastic element 43 is a spring element. By connecting one end of the spring to the first gripper 10 and the other end to the second gripper 20, the spring element is stretched when the driving assembly 30 drives the first gripper 10 and the second gripper 20 to open. During this process, the spring element is in a stretched state, and its stored elastic potential energy limits the opening range of the first gripper 10 and the second gripper 20, thus protecting the grippers from over-opening. When the grippers need to close, the spring element uses its stored elastic potential energy to help the first gripper 10 and the second gripper 20 quickly and accurately return to their initial positions.

[0048] In summary, when a silver medallion needs to be clamped, the drive assembly 30 drives the first gripper 10 and the second gripper 20 to gradually close, clamping the medallion for processing. At this time, the connecting elastic element 43 in the buffer assembly 40 is in its natural state. If the medallion is too small, the first buffer element 41 and the second buffer element 42 gradually approach each other, allowing them to abut against each other and preventing damage to small medallions from excessive force. The first buffer element 41 and the second buffer element 42 are positioned opposite each other. When it is necessary to release the medallion, the drive assembly 30 is activated, pushing the first gripper 10 and the second gripper 20 to gradually open. The connecting elastic element 43 connecting the first gripper 10 and the second gripper 20 is stretched. As the first gripper 10 and the second gripper 20 open, the elastic potential energy stored in the connecting elastic element 43 resists the thrust of the drive assembly 30, limiting the further opening of the grippers and preventing the root connection structure of the grippers from bearing excessive impact loads.

[0049] In one specific embodiment, both the first gripper 10 and the second gripper 20 include a rotating part 11 and a gripper part 12 connected to the rotating part 11. The rotating part 11 is disposed at one end near the drive assembly 30. The first buffer 41, the second buffer 42, and the connecting elastic member 43 are disposed adjacent to each other on the rotating part 11. The first buffer 41 and the second buffer 42 are disposed on the side near the drive assembly 30, and the connecting elastic member 43 is disposed on the side near the gripper part 12.

[0050] Specifically, the rotating part 11 and the gripper part 12 are an integral structure. The rotating part 11 is the part where the buffer assembly 40 is installed. When the first gripper 10 and the second gripper 20 open and close, the first gripper 10 and the second gripper 20 will rotate around the rotating part 11 as the rotation point. The gripper part 12 directly acts on the silver medal, responsible for clamping and fixing the silver medal, ensuring its stability and positioning accuracy during the processing.

[0051] Furthermore, when the first gripper 10 and the second gripper 20 open, the distal gripper portion 12 will separate, and the rotating portion 11 will move closer to the central axis of the drive assembly 30. The installation positions of the first buffer 41 and the second buffer 42 are located in the convergence area of ​​the movement trajectory of the rotating portion 11.

[0052] Furthermore, when the grippers close to a certain extent, the buffer can first contact and absorb the impact force, effectively preventing damage to the silver medallion surface due to excessive force. Simultaneously, the buffer also reduces the load on the drive assembly 30 during the gripper closing process, extending its service life. The connecting elastic element 43 not only provides additional buffering and restoring force for the opening and closing of the grippers, but also limits the opening amplitude of the grippers when they open, preventing the gripper root connection structure from bearing excessive impact loads due to over-opening. In addition, the restoring force of the connecting elastic element 43 helps the grippers quickly and accurately return to their initial position when closing, ensuring machining accuracy.

[0053] In one specific embodiment, the buffer assembly 40 further includes a first connector 44 and a second connector 45. The first connector 44 is disposed on the first gripper 10, and the second connector 45 is disposed on the second gripper 20. One end of the first buffer 41 and the connecting elastic member 43 is disposed on the first connector 44, and the other end of the second buffer 42 and the connecting elastic member 43 is disposed on the second connector 45.

[0054] Specifically, the first connector 44 and the second connector 45 are fixed to the first gripper 10 and the second gripper 20 respectively by screws, bolts, etc. They act as a bridge between the buffer assembly 40 and the gripper, ensuring that the buffer assembly 40 (including the buffer element and the connecting elastic element 43) can be firmly installed on the gripper and will not loosen or fall off during operation, thereby ensuring the overall stability and reliability of the fixture. By designing the first connector 44 and the second connector 45, the quick installation and removal of the buffer assembly 40 and the gripper can be easily achieved.

[0055] In one specific embodiment, the first buffer member 41 includes a first buffer rod 411 and a first buffer ring 412. One end of the first buffer rod 411 is disposed on the first connecting member 44, and the first buffer ring 412 is sleeved on the other end of the first buffer rod 411. The second buffer member 42 includes a second buffer rod 421 and a second buffer ring 422. One end of the second buffer rod 421 is disposed on the second connecting member 45, and the second buffer ring 422 is sleeved on the other end of the second buffer rod 421. The first buffer rod 411 and the second buffer rod 421 are parallel to the connecting elastic member 43, and the first buffer ring 412 and the second buffer ring 422 are arranged facing each other.

[0056] Specifically, the first buffer rod 411 and the second buffer rod 421 are fixedly connected to the first connector 44 and the second connector 45, respectively, providing stable guidance and support for the first buffer ring 412 and the second buffer ring 422. The buffer rings typically adopt a ring design, allowing them to surround the top area of ​​the buffer rods and form pressure-shock protection for the opposing buffer rings. The first buffer ring 412 and the second buffer ring 422 can be made of an elastic material, such as rubber, silicone, or other polymer materials. These materials can deform under pressure, thereby absorbing and dispersing pressure. The first buffer ring 412 and the second buffer ring 422 can be installed on the silver medal in various ways, such as by adhesive, snap-fit, or threaded connection, ensuring that the buffer rings are firmly fixed to the silver medal and will not fall off or shift under pressure. During the clamping process, they ensure that the first buffer ring 412 and the second buffer ring 422 can make accurate and smooth contact, thereby effectively limiting the excessive closing of the clamps and preventing damage to the surface of the silver medal due to excessive local pressure.

[0057] Furthermore, the first buffer ring 412 and the second buffer ring 422, as the direct contact parts of the buffer assembly 40, have a large contact area, which can more effectively disperse the impact force when the jaws close, thereby protecting the silver medal from damage. The first buffer rod 411 and the second buffer rod 421 are arranged parallel to the connecting elastic element 43, ensuring the stability of the buffer assembly 40 during the opening and closing of the jaws and avoiding precision loss due to skewness.

[0058] In one specific embodiment, the drive assembly 30 includes a mounting plate 31 and a piston rod 32 clamped within the mounting plate 31. The piston rod 32 extends out of the mounting plate 31 and is movably connected to the first gripper 10 and the second gripper 20.

[0059] Specifically, the mounting plate 31, as the basic component of the drive assembly 30, provides stable support and fixation for the piston rod 32. It ensures that the piston rod 32 maintains a stable movement trajectory when the drive grippers open and close, thereby improving the overall stability and accuracy of the fixture. Through the mounting plate 31, various components of the drive assembly 30 (such as the piston rod 32, cylinder, etc.) can be integrated together.

[0060] Furthermore, the piston rod 32 is a key component in the drive assembly 30. It can be pushed manually or by a cylinder, and the piston rod 32 will extend or retract into the mounting plate 31 accordingly, thereby driving the opening and closing of the gripper.

[0061] Furthermore, when it is necessary to clamp the silver medallion, the piston rod 32 is pushed out of the mounting plate 31. The piston rod 32 is connected to the first gripper 10 and the second gripper 20 via a movable connection. Therefore, the extension of the piston rod 32 will cause the grippers to gradually open. During the opening process, the connecting elastic element 43 (such as a spring) is stretched and stores elastic potential energy to resist the thrust of the drive assembly 30 and limit the excessive opening of the grippers. When it is necessary to clamp the silver medallion, the piston rod 32 retracts into the mounting plate 31, causing the grippers to gradually close. During the closing process, if the size of the silver medallion is too small, the first buffer element 41 and the second buffer element 42 will abut against each other, thereby limiting the further closing of the grippers and preventing damage to the surface of the silver medallion.

[0062] In one specific embodiment, the drive assembly 30 further includes a first drive rod 33 and a second drive rod 34. One end of the first drive rod 33 and the second drive rod 34 are clamped between the rotating portion 11 of the first gripper 10 and the second gripper 20. The other end of the first drive rod 33 is disposed on the piston rod 32, and the other end of the second drive rod 34 is connected to the second gripper 20. The piston rod 32 has a clamping groove 32a, and the first drive rod 33 and the second drive rod 34 intersect in the clamping groove 32a.

[0063] Specifically, the first drive rod 33 and the second drive rod 34, as key components connecting the piston rod 32 and the gripper, are responsible for converting the movement of the piston rod 32 into the opening and closing motion of the gripper. By precisely controlling the extension and retraction of the piston rod 32, precise control of the opening and closing amplitude of the gripper can be achieved, thereby avoiding damage to the silver medal or wear of the clamps caused by excessive opening or closing. The clamping groove 32a opened on the piston rod 32 provides precise positioning and stable support for the first drive rod 33 and the second drive rod 34. By ensuring the correct position of the drive rod within the clamping groove 32a, precise control of the opening and closing amplitude of the gripper can be achieved, improving machining accuracy.

[0064] Furthermore, one end of the first drive rod 33 and the second drive rod 34 intersect in the clamping groove 32a, and the first drive rod 33, the second drive rod 34 and the piston rod 32 are fixed at a point by screws, bolts, screws, etc., so that when the piston rod 32 pushes the first gripper 10 and the second gripper 20 to close or open, the first gripper 10 and the second gripper 20 can rotate at the point in the clamping groove 32a where the first drive rod 33 and the second drive rod 34 intersect.

[0065] In one specific embodiment, the first gripper 10 includes a first fixing hole 10a and a first fixing member 13. The first fixing hole 10a is disposed on the rotating part 11 of the first gripper 10. The first drive rod 33 has a second fixing hole 33a. The first fixing hole 10a and the second fixing hole 33a are arranged opposite each other. The first fixing member 13 passes through the first fixing hole 10a and the second fixing hole 33a to fix the first drive rod 33 and the first gripper 10.

[0066] Specifically, the first fixing member 13 can be any fixing structure such as a bolt or a pin. There are at least two first fixing holes 10a to ensure the fixation between the first drive rod 33 and the second gripper 20. The combination of the first fixing holes 10a and the first fixing member 13 ensures a stable connection between the first drive rod 33 and the first gripper 10. By aligning the first fixing holes 10a and the second fixing holes 33a and fixing them with the first fixing member 13 (such as a bolt or pin), relative movement or loosening between the first drive rod 33 and the first gripper 10 during the driving process can be effectively prevented, thereby ensuring the accuracy and stability of the gripper's movement.

[0067] In one specific embodiment, the second gripper 20 includes a third fixing hole 20a and a second fixing member 21. The third fixing hole 20a is disposed on the rotating part 11 of the second gripper 20. The second drive rod 34 has a fourth fixing hole 34a, which is directly opposite to the third fixing hole 20a. The second fixing member 21 passes through the third fixing hole 20a and the fourth fixing hole 34a to fix the second drive rod 34 and the second gripper 20.

[0068] Specifically, the second fixing member 21 can be any fixing structure such as a bolt or a pin. The combination of the third fixing hole 20a and the second fixing member 21 ensures a stable connection between the second drive rod 34 and the second gripper 20. By precisely aligning the third fixing hole 20a and the fourth fixing hole 34a, and fixing them with the second fixing member 21 (such as a bolt or pin), relative movement or loosening between the second drive rod 34 and the second gripper 20 during the driving process can be effectively prevented, thereby ensuring the accuracy and stability of the gripper's movement.

[0069] In one specific embodiment, the first gripper 10 includes a first gripping arm 14 and a second gripping arm 15 connected to the first gripping arm 14. The first gripping arm 14 is connected to the rotating part 11 of the first gripper 10. The included angle between the first gripping arm 14 and the second gripping arm 15 is denoted as A, and A satisfies the relationship: 90° < A < 120°.

[0070] Specifically, by setting the included angle A between 90° and 120°, the first clamping arm 14 and the second clamping arm 15 form a shape and angle adapted to the silver medal, thereby better securing the medal and allowing the jaws to apply clamping force more evenly when closed, reducing the risk of surface damage to the medal due to uneven force distribution. When clamping the medal, the second clamping arm 15 and the first clamping arm 14 work together to form a stable clamping structure, preventing the medal from moving during processing.

[0071] In one specific embodiment, the drive assembly 30 further includes an abutment 50, one end of which is movably connected to the mounting plate 31, and the other end of which is clamped between the first clamping claw 10 and the second clamping claw 20 and is capable of abutting against the silver medal.

[0072] Specifically, the abutment 50 further enhances the stability of the grippers when holding the silver medallion. The direct contact between the abutment 50 and the silver medallion ensures that the grippers hold the medallion more securely during the closing process, preventing processing errors caused by unstable gripping. In this embodiment, the abutment 50 includes a fixed plate and an abutment post connected to the fixed plate. A sliding groove between the fixed plate and the mounting plate 31 adjusts the distance between the abutment post on the fixed plate and the silver medallion, allowing the abutment 50 to be flexibly adjusted according to actual needs. This design helps accommodate silver medallions of different sizes and shapes, improving the versatility and flexibility of the fixture.

[0073] Therefore, the aforementioned silver medal fixture 100 is designed with a structure comprising a first gripper 10, a second gripper 20, a drive assembly 30, and a buffer assembly 40. The first gripper 10 and the second gripper 20 are positioned opposite each other, and the drive assembly 30 controls their opening and closing. The buffer assembly 40 includes a first buffer 41, a second buffer 42, and a connecting elastic element 43, which are arranged parallel between the grippers. When the drive assembly 30 drives the grippers to open to a certain extent, the connecting elastic element 43 prevents metal fatigue cracks caused by repeated impacts on the gripper root connection structure. Simultaneously, the connecting elastic element 43 provides necessary buffering and resetting force when the grippers reset, ensuring the stability of the gripper opening and closing accuracy. When the drive assembly 30 drives the grippers to close, the first buffer 41 and the second buffer 42 abut against each other, effectively limiting excessive gripping and preventing excessive clamping force that could damage the silver medal.

[0074] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
