Description

Technical Field

[0001] This utility model relates to the field of automatic clamping technology for diamond scanning, specifically an automatic clamping mechanism for diamond scanning. Background Technology

[0002] Diamond scanning is a crucial step in the production, processing, and identification of diamonds. Scanning allows for the precise acquisition of vital information about a diamond's internal structure, flaw distribution, and external morphology, providing a basis for diamond quality assessment and processing optimization. During the scanning process, the stability and efficiency of holding the diamond directly impact the scanning quality and efficiency.

[0003] Existing clamping mechanisms such as Figure 1 As shown, during clamping, the operator needs to continuously rotate the push rod, which moves within the fixed rod until it reaches the top and clamps the diamond with the pressure head. Because the overall clamping mechanism is relatively small, the operator has to rotate it a relatively large number of times, making the operation extremely difficult and potentially causing over-clamping of the diamond. This is especially problematic when cleaning a clamped diamond, as some of the liquid may remain in the threaded gap between the push rod and the fixed rod after cleaning, which can cause corrosion over time and prevent the push rod from rotating, necessitating the replacement of the clamping mechanism.

[0004] In practical use, this can lead to cumbersome operation, which not only fails to improve work efficiency but also increases the workload of operators. Liquid seeps into critical components, causing corrosion and damage to the equipment. To address these issues, we provide an automatic clamping mechanism for diamond scanning. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic clamping mechanism for diamond scanning.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automatic clamping mechanism for diamond scanning, comprising a fixed frame, a fixed rod fixed at the bottom of the fixed frame, a top rod passing through the fixed rod, a pressure head fixed below the cross-shaped section of the fixed frame, and the pressure head being directly above the top rod, a groove being formed in the fixed rod, a sliding rod being disposed in the groove, a movable slider being sleeved on the surface of the sliding rod, a spring being disposed at the bottom end of the slider, and the spring being sleeved on the surface of the sliding rod, the bottom end of the spring being fixed to the inner wall of the groove, and two sealing gaskets being sleeved on the surface of the top rod, the sealing gaskets being located above and below the fixed rod respectively.

[0009] Furthermore, a connecting block is fixed to the bottom end of the top rod.

[0010] Furthermore, a placement groove is provided above the top rod, and the surface of the placement groove is provided with an inclined arc surface.

[0011] Furthermore, the bottom end of the pressure head has an internal concave shape with a surrounding convex shape.

[0012] Furthermore, a fixing plate is provided on the surface of the fixing rod, and an inclined arc surface is provided at the connection between the fixing plate and the fixing rod.

[0013] Furthermore, a limit ring is provided on the surface of the fixing rod, and the limit ring is located at the bottom end of the fixing plate.

[0014] (III) Beneficial Effects:

[0015] Compared with existing technologies, this automatic clamping mechanism for diamond scanning has the following advantages:

[0016] I. This utility model employs a structure in which springs, sliding rods, and sliders are evenly designed within a fixed rod. After the operator pulls the top rod, the spring force allows for rapid clamping of the diamond using the top rod and pressure head. Compared to manual rotation clamping, this automatic and rapid-response clamping action significantly saves time, improves work efficiency, and avoids over-clamping of the diamond. It is particularly suitable for work scenarios requiring the rapid clamping of large quantities of diamonds for scanning.

[0017] Second, this utility model has an inclined arc surface on the surface of the placement groove that fits the bottom surface of the diamond, and there is also an inclined arc surface at the connection between the fixing plate and the fixing rod. This design allows the diamond to naturally adapt during placement and clamping, reducing the time for adjustment and positioning, and further improving work efficiency.

[0018] Third, this utility model effectively seals the space between the fixed rod and the top rod by attaching two sealing gaskets to the surface of the top rod, located above and below the fixed rod respectively. This prevents liquid from entering between the fixed rod and the top rod during cleaning operations after diamond clamping, thus preventing the slide rod, slider, and spring in the groove from rusting due to liquid corrosion. This ensures the normal operation of these key components, reduces the occurrence of failures where the top rod cannot be pulled up or down due to component corrosion, extends the service life of the entire clamping mechanism, and reduces maintenance costs and frequency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] like Figure 1-6 As shown, this utility model provides a technical solution: an automatic clamping mechanism for diamond scanning, including a fixed frame 1, a fixed rod 6 fixed at the bottom of the fixed frame 1, a top rod 3 passing through the fixed rod 6, a placement groove 4 for placing diamonds above the top rod 3, the surface of the placement groove 4 having an inclined arc surface that fits with the bottom surface of the diamond, and an inclined arc surface at the connection between the fixed plate 7 and the fixed rod 6. This design allows the diamond to naturally adapt during placement and clamping, reducing adjustment and positioning time and further improving work efficiency. The surface of the fixed rod 6 has a fixed plate 7, and the connection between the fixed plate 7 and the fixed rod 6 has an inclined arc surface. The surface of the fixed rod 6 has a limit ring 8, which is located at the bottom of the fixed plate 7. The limit ring 8 on the surface of the fixed rod 6 can limit the fixed plate 7, ensuring the stability and accuracy of the entire clamping structure and preventing the clamping effect from being affected by changes in the position of components during operation.

[0028] The fixing frame 1 has a pressure head 2 fixed below the cross intersection. The bottom end of the pressure head 2 is concave inside and convex around it. The pressure head 2 is located directly above the top rod 3. This design can cooperate with the top rod 3 to clamp the diamond more stably. The concave inside can better accommodate the diamond, while the convex around it plays a role in positioning and reinforcement, ensuring that the diamond will not shake or shift during scanning, thus improving the accuracy of scanning. The fixing rod 6 has a groove 10, in which a sliding rod 13 is set. A movable slider 12 is sleeved on the surface of the sliding rod 13. A spring 11 is set at the bottom end of the slider 12, and the spring 11 is sleeved on the surface of the sliding rod 13. The bottom end of the spring 11 is fixed to the inner wall of the groove 10. The fixing rod 6 adopts a structure in which the spring 11, the sliding rod 13 and the slider 12 are evenly designed. After the operator pulls the push rod 3, the diamond can be quickly clamped by the push rod 3 and the pressure head 2 under the elastic force of the spring 11. Compared with the manual rotation clamping method, this automatic and fast-response clamping action can significantly save time, improve work efficiency, and avoid over-clamping of diamonds. It is especially suitable for work scenarios that require a large number of diamonds to be clamped quickly for scanning.

[0029] Specifically, two sealing gaskets 5 are fitted onto the surface of the top rod 3, located above and below the fixed rod 6 respectively. This effectively seals the space between the fixed rod 6 and the top rod 3, preventing liquid from entering between the fixed rod 6 and the top rod 3 during cleaning after diamond clamping. This prevents the slide rod 13, slider 12, and spring 11 in the groove 10 from rusting due to liquid corrosion, ensuring the normal operation of these critical components. It also reduces the occurrence of failures where the top rod 3 cannot be pulled up or down due to component corrosion, extends the service life of the entire clamping mechanism, and reduces maintenance costs and frequency. The bottom end of the top rod 3 is fixed with a connecting block 9 for connection to an external scanning device.

[0030] Working principle: During use, the operator pulls the top rod 3. When the top rod 3 moves, the slider 12 inside the groove 10 slides on the surface of the slide rod 13 and squeezes the spring 11. Then, the selected diamond is placed on the placement groove 4. The top rod 3 is released, and the top rod 3 clamps the diamond and the pressure head 2 under the action of the spring 11. Then, the operator cleans the clamped diamond, preheats it after cleaning, and then connects it to the scanning equipment through the connecting block 9. It is then accurately installed with the scanning equipment through the positioning plate and the limiting ring 8 for scanning.
