[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] On the one hand, embodiments of this utility model provide an automatic centering tensioning clamp, such as Figure 1-6 As shown, it includes a fixed base 1, an adjustable plate 2 that can be hinged to the fixed base 1 and locked, a first drive assembly 3 on the adjustable plate 2, a power output end of the first drive assembly 3 is rotatably driven to connect an adapter 4, a product base 5 is mounted on the side of the adapter 4 away from the first drive assembly 3, and a positioning post 6 for placing the product is provided on the product base 5 (the product base 5 and the positioning post 6 can be designed as one piece to improve the overall strength).

[0049] The positioning post 6 is provided with an axially extending first mounting hole 61 and a radially extending second mounting hole 62 connected to the first mounting hole 61. The first mounting hole 62 is provided with a driving member 63, and the second mounting hole 62 is provided with a positioning block 64 that can extend / retract from the second mounting hole 62.

[0050] A second drive assembly 7 is provided on the adapter 4 between the adapter 4 and the product base 5. The power output end of the second drive assembly 7 drives the drive component 63, and the drive component 63 drives the positioning block 64. After the positioning block 64 extends out of the second mounting hole 62, it can tighten and fix the product 9 sleeved on the positioning post 6. The product 9 can be various ring-shaped / tube-shaped products, such as (smart) rings, bracelets, etc.

[0051] In use, first set and fix the angle of the adjustment plate 2, then place the product 9 on the positioning post 6. At this time, the second drive assembly 7 drives the drive component 63, which in turn drives the positioning block 64. After the positioning block 64 extends out of the second mounting hole 62, it tightens and fixes the product 9 sleeved on the positioning post 6. Then, the first drive assembly 3 rotates according to the process requirements to drive the adapter 4. The adapter 4 drives the second drive assembly 7 and the product base 5 to rotate. The positioning post 6 on the product base 5 drives the product 9 to rotate, completing the surface treatment, etc. After the surface treatment is completed, reverse the above process to retract the positioning block 64 and release the product 9.

[0052] This utility model discloses an automatic centering and tensioning clamp, comprising a fixed base 1, on which an adjustable plate 2, capable of adjusting and locking the axial angle, is hinged, making it convenient to use; the adjustable plate 2 is provided with a first drive assembly 3, the power output end of which is rotatably driven by an adapter 4, allowing rotation according to process requirements, making it convenient to use; the positioning post 6 is provided with an axially extending first mounting hole 61 and a radially extending second mounting hole 62 communicating with the first mounting hole 61; the first mounting hole 61 is provided with a drive component 63, and the second mounting hole 62... The 2 is equipped with a positioning block 64 that can extend / retract from the second mounting hole 62. The power output end of the second drive assembly 7 drives and connects to the drive component 63, which in turn drives and connects to the positioning block 64. After the positioning block 64 extends out of the second mounting hole 62, it can tighten and fix the product 9 sleeved on the positioning post 6. Through the coordinated cooperation of the positioning post 6, the second drive assembly 7, the drive component 63, and the positioning block 64, the ring-shaped / tube-shaped products can be effectively positioned, clamped, and fixed from the inside without affecting the processing of the outer surface of the product, thus ensuring the stability and reliability of the product processing.

[0053] The driving connection between the driving component 63 and the positioning block 64 can be any of the methods readily conceived by those skilled in the art, such as gear transmission connection, linkage connection, etc. In this embodiment of the present invention, the following method is preferred:

[0054] The driving component 63 is a slider that can move along the axial direction of the positioning post 6. The positioning block 64 has a through hole 641 for the slider to pass through, and the slider has a wedge-shaped surface 631 for driving the positioning block 64 to move. In this way, the slider passes through the through hole 641 and is provided with a wedge-shaped surface 631. When the slider moves along the axial direction of the positioning post 64, it can drive the positioning block 64 to move in the radial direction of the positioning post 64.

[0055] In some embodiments of this utility model, an elastic element 642 (specifically a spring) for extending the positioning block 64 may be provided in the second mounting hole 62, and a wedge-shaped surface 631 is provided on the side of the slider away from the opening of the second mounting hole 62. In this case, the elastic element 642 can extend the positioning block 64, and the wedge-shaped surface 631 is used to retract the positioning block 64.

[0056] Specifically, when product 9 needs to be picked up or placed, the second drive assembly 7 drives the slider to extend. Since there is a mutual fitting angle between the slider and the positioning block 64 (which can be flexibly set according to requirements, as long as they fit each other), the slider compresses the positioning block 64 and the elastic element 642 when it extends. At this time, the positioning block 64 does not play a positioning or clamping role, and the product can be picked up or placed smoothly. When product 9 is placed and needs to be processed, the second drive assembly 7 drives the slider to retract. The positioning block 64 is pushed out by the elastic force of the elastic element 642. At this time, the positioning block 64 extends and embeds into the inner cavity of product 9 to perform positioning and clamping actions.

[0057] like Figure 4-6 As shown, the outer end face of the positioning block 64 (i.e., the end away from the elastic element 642) can be provided with an arc-shaped pushing surface 643 that matches the inner surface of the product 9 (the specific design can be based on the characteristics of the inner cavity of the product 9). In this way, even if the product 9 is slightly off-center during placement, it can be automatically corrected and positioned by the action of the arc-shaped pushing surface 643.

[0058] In some embodiments of this utility model, there can be two elastic elements 642, respectively disposed on both sides of the inner end face of the positioning block 64. The two elastic elements 642 can generate a uniform pushing force, so that the positioning block 64 can be directly facing and pushing the product 9, thereby better fixing the product 9. The inner end face of the positioning block 64 can be provided with elastic element mounting holes (not shown), which facilitates the installation or replacement of the elastic elements 642. In addition, the head of the positioning block 64 can also be designed to conform to the characteristics of the inner cavity of the product 9 (specifically, it can be mutually cooperating protrusions, depressions, etc.). Therefore, the positioning block 64 can accurately position the product 9 while playing a fixing role. The product holding force can be controlled by controlling the compression amount of the elastic element 642 or by replacing the elastic element 642.

[0059] In some embodiments of this utility model, the positioning post 6 may have flat cut surfaces 65 on opposite sides along the axial direction of the positioning post 6, wherein the second mounting hole 62 penetrates one of the flat cut surfaces 65, and the end of the elastic member 642 abuts against the side wall of the positioning post near the other flat cut surface; the product base 5 may have limiting posts 8 on both sides of the positioning post 6 that cooperate with the outer surface of the product 9. Since the outer surface of the product 9 has features (such as grooves) that cooperate with the limiting posts 8, the product 9 can only be placed on the positioning post 6 in a fixed / set direction. Since the positioning post 6 has flat cut surfaces on opposite sides, the product 9 has space to adjust its position / direction. The outer end face of the positioning block 64 has an arc-shaped pushing surface 643 that cooperates with the inner surface of the product 9. In this way, the positioning post 6, the arc-shaped pushing surface 643 of the positioning block 64, and the limiting posts 8 can better achieve precise centering of the product 9. In specific implementation, the matching limiting posts 8 can be replaced according to the different products 9 being processed.

[0060] In some embodiments of this utility model, the bottom of the positioning post 64 may be provided with a step 66 to increase the height of the product 9 and facilitate surface treatment. A pair of connecting plates 41 may be provided on both sides of the adapter 4 and the product base 5. The pair of connecting plates 41 are fixed to the adapter 4 and the product base 5 by screws 42, ensuring a firm fixation and structural stability. The adapter 4 may be provided with a photoelectric module 43 for sensing and feedback the rotation angle of the first driving component 3. Thus, during production, the photoelectric module 43 can sense and feedback the rotation angle of the first driving component 3 to ensure production efficiency.

[0061] The first drive component 3 can be a servo motor, and the second drive component 7 can be a cylinder, which is low in cost and easy to use.

[0062] The fixed base 1 may include a base plate 11 and a vertical plate 12 perpendicular to the base plate 11. A pair of side plates 13 are provided on both sides of the base plate 11 and the vertical plate 12. An adjustment plate 2 is hinged to the pair of side plates 13 near the angle between the base plate 11 and the vertical plate 12. In this way, not only is the structure stable, but the position of the adjustment plate 2 is also easy to adjust.

[0063] An arc-shaped groove 131 can be provided on the side plates 13 away from the hinge of the adjusting plate 2. Guide posts 21 that cooperate with the arc-shaped groove 131 are provided on both sides of the adjusting plate 2. In this way, the adjusting plate can be guided to adjust the angle better. The side plates 13 can be fan-shaped side plates. A cutout 132 can be provided on the side plates 13 to facilitate observation of the position of the adjusting plate 2. The adjusting plate 2 can be provided with a locking element (not shown) to fix the position of the adjusting plate 2. The locking element can adopt various conventional technologies, such as locking bolts.

[0064] In summary, this utility model mainly relates to an automatic centering and tensioning fixture for ring / tube products. This device can automatically center and align ring / tube products, ensuring accurate positioning of the product on the fixture. In other words, this device can achieve precise product positioning and effectively fix the product, ensuring stability and reliability during product processing. Furthermore, by using this fixture solution in conjunction with pneumatic and electrical components, an automated solution for multi-angle laser engraving of products can be achieved.

[0065] For ring-shaped / tube-shaped products with appearance requirements, this utility model can prevent contact with the product's appearance surface during subsequent processing. It can effectively position the product while also fixing it, thereby improving processing efficiency and reducing defects such as bumps and scratches on the product's appearance surface.

The structure of the automatic centering and tensioning clamp is the same as above, and will not be described again here. The surface treatment device may include an engraving machine and / or a sandblasting machine, etc.

[0067] The product processing system of this utility model includes an automatic centering and tensioning clamp. The automatic centering and tensioning clamp includes a fixed base 1, on which an adjustable plate 2, capable of adjusting and locking the axial angle, is hinged. The adjustable plate 2 is provided with a first drive assembly 3, the power output end of which is rotatably driven and connected to an adapter 4, enabling rotation according to process requirements and facilitating use.
