Description

Technical Field

[0001] This utility model relates to the field of diamond processing technology, specifically to a diamond processing support base. Background Technology

[0002] As the hardest material in nature, diamond requires a high degree of stability from the fixing device during its processing. Traditional diamond processing support bases typically use rigid clamping structures. However, due to the irregular shape and sharp edges of raw diamonds, rigid clamping can easily lead to localized stress concentration, causing the raw diamond to crack or the clamping to loosen.

[0003] To address these issues, existing technologies propose adding flexible pads such as rubber or polyurethane to the contact surface of the chuck. While this solution alleviates stress concentration, the intense vibrations generated during diamond cutting can cause micro-displacement between the flexible pads and the metal chuck. Over time, this can lead to pad peeling or tearing, requiring frequent machine shutdowns for replacement. Therefore, existing technologies further employ flexible straps to reinforce the diamond. However, the high-speed rotating cutter can cause slight wobbling in the tightly bound straps during cutting, which can affect the surface smoothness of the cut when the diamond is subjected to radial force from the cutter. Utility Model Content

[0004] The purpose of this invention is to provide a diamond processing support base to solve the technical problem in the prior art where the connection of flexible straps may cause shaking during diamond processing.

[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0006] A diamond processing support base includes at least two mounting brackets. Each mounting bracket is connected to a stud by a threaded engagement. The stud has a strip-shaped through hole, and a flexible strap is slidably disposed within the strip-shaped through hole. The flexible strap can slide along the axial direction of the stud within the strip-shaped through hole. The flexible strap has a through square hole, and the other end of the flexible strap is connected to another strip-shaped through hole through the through square hole. The middle part of the flexible strap is curled to form a socket area for connecting diamonds.

[0007] Clamping blocks are provided on both sides of the socket area. Two clamping blocks are mounted on the mounting bracket via a reset elastic element. The two clamping blocks are slidably mounted on the mounting bracket in a manner that approaches and moves away from the diamond. Two driving blocks are provided on both sides of the clamping blocks for driving the clamping blocks to slide. The driving blocks are mounted on the stud via a limiting structure. The rotation of the stud drives the driving blocks to push the clamping blocks to slide.

[0008] As a preferred embodiment of this utility model, a limiting plate is provided at the end of the flexible strap, and the limiting plate is disposed on the opening of the strip-shaped perforation.

[0009] In a preferred embodiment of this utility model, the clamping block is a right-angled trapezoid, with its planar side facing the socket area and its inclined side facing the driving block. The driving block slides from the small end to the large end of the clamping block to push the clamping blocks to move towards each other and clamp the diamond.

[0010] As a preferred embodiment of this utility model, the limiting structure includes an annular collar, which is coaxially and rotatably mounted on the stud. The driving block is fixedly disposed on the annular collar, and a limiting groove is formed on the driving block. The length direction of the limiting groove is parallel to the axial direction of the stud. A limiting post is slidably disposed in the limiting groove, and the limiting post is fixedly connected to the mounting bracket.

[0011] In a preferred embodiment of this utility model, a plurality of balls are rolled at the bottom end of the limiting post, and the limiting post is connected to the limiting groove through the balls.

[0012] In a preferred embodiment of this utility model, the mounting bracket includes a vertical plate, the stud is screwed onto the vertical plate, a support plate is fixedly provided on the top of the vertical plate, and the limiting post is fixedly provided on the support plate.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention utilizes a flexible strap to tightly wrap the diamond and a rigid clamping block to fix and hold the diamond. By increasing the contact area and applying clamping strength, it can improve stability during the fixing process while ensuring firm clamping, reduce local stress during clamping, and improve stability during cutting. Furthermore, the rotation of the stud synchronously drives the flexible strap and clamping block to work, thereby reducing operation steps and improving operation efficiency.

[0021] 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.

[0022] like Figures 1 to 3 As shown, this utility model provides a diamond processing support base, including at least two mounting brackets 1. Each mounting bracket 1 is threadedly connected to a stud 2. The stud 2 has a strip-shaped through-hole 3 along its axial direction, penetrating the side wall of the stud 2 for slidingly mounting a flexible strap 4. The flexible strap 4 is slidably mounted within the strip-shaped through-hole 3. The flexible strap 4 is made of a high-strength, wear-resistant flexible material, such as nylon or aramid fiber composite material, and can slide freely within the strip-shaped through-hole 3 along the axial direction of the stud 2 to prevent the flexible strap 4 from moving synchronously when the stud 2 moves axially. The flexible strap 4 has a through square hole 5 in its middle, and a connecting area 6 is formed in the bent middle section of the flexible strap 4. The other end of the flexible strap 4 is inserted through the through square hole 5 into the strip-shaped through-hole 3 of another stud 2 and is connected to this strip-shaped through-hole 3 for limiting connection. Figure 1 As shown. The flexible binding tape 4 naturally curls in the middle to form a socket area 6, which is used to attach and fix the diamond to be processed. By rotating the stud 2, the flexible binding tape 4 is driven to curl onto the stud 2, thereby reducing the diameter of the socket area 6 and thus securing the diamond.

[0023] Clamping blocks 7 are provided on both sides of the socket area 6. The two clamping blocks 7 are mounted on the mounting bracket 1 via a reset elastic element. The two clamping blocks 7 are slidably mounted on the mounting bracket 1, moving closer to and further away from the diamond. Driving blocks 8 are provided on both sides of the clamping blocks 7 to drive their sliding. The driving blocks 8 are mounted on the stud 2 via a limiting structure. The rotation of the stud 2 drives the driving blocks 8 to push the clamping blocks 7 to slide. Specifically, the clamping blocks 7 are slidably mounted on the mounting bracket 1 via a sliding groove. The reset elastic element can be a spring, fixedly mounted in the sliding groove and connected to the clamping block to drive the clamping blocks 7 back to their original position. The clamping blocks 7 can move closer to or further away from the diamond, thereby clamping and releasing the diamond. The driving blocks 8 are mounted on the stud 2 via a limiting structure. The driving blocks 8 are located on one side of the clamping blocks 7. As the stud 2 rotates, the driving blocks 8 push the clamping blocks 7 to clamp the diamond. The rotation of stud 2 causes the flexible binding tape 4 to curl around the outside of stud 2, thus securing the diamond. Simultaneously, the axial movement of stud 2 also causes the drive block 8 to move synchronously. When the drive block 8 moves along the axis of stud 2, it contacts the clamping block 7 and slides, thus clamping the diamond in the socket area 6. When stud 2 rotates in the opposite direction, causing the drive block 8 to move away from the clamping block 7 and no longer push against it, the reset elastic element pulls the clamping block 7 back, freeing it from clamping the diamond and allowing it to be removed, thus forming a reusable cycle.

[0024] During operation, by rotating the stud 2, the annular collar 10 moves axially forward or backward along the thread of the stud 2, driving the drive block 8 to move along the axis of the stud 2. The inclined surface of the drive block 8 contacts the inclined surface of the clamping block 7 and slides from the small end to the large end of the clamping block 7, thereby pushing the clamping block 7 to move towards each other and clamping and fixing the diamond in the sleeve area 6. The end of the flexible strap 4 is provided with a limiting plate 9 adapted to the opening of the strip-shaped perforation 3. The limiting plate 9 is set on the opening of the strip-shaped perforation 3 and can prevent the flexible strap 4 from disengaging from the strip-shaped perforation 3 during sliding, ensuring the stability of the strap.

[0025] Among them, such as Figure 1 and Figure 3 As shown, the clamping block 7 is a right-angled trapezoid. The flat side of the clamping block 7 faces the socket area 6, and the inclined side of the clamping block 7 faces the driving block 8. The driving block 8 slides from the small end to the large end of the clamping block 7 to push the clamping block 7 to move towards each other and clamp the diamond.

[0026] The drive block 8 slides from the small end to the large end of the clamping block 7, which can push the clamping block 7 to slide radially along the stud 2, thereby approaching the socket area 6 to clamp the diamond.

[0027] Furthermore, a flexible pad, such as silicone or polyurethane material, is added to the planar side of the clamping block 7 to further alleviate stress concentration on the diamond during clamping. The bevel angle of the drive block 8 matches the bevel angle of the clamping block 7 to ensure the stability of force transmission during the pushing process.

[0028] Furthermore, to improve the durability of the flexible strap 4, a wear-resistant coating, such as a polytetrafluoroethylene coating, can be added to the inner side of the central socket area 6 of the flexible strap 4 to reduce friction and wear with the diamond during high-speed rotary cutting. Reinforcing ribs can also be provided on the inner wall of the through-hole 5 of the flexible strap 4 to improve its tensile strength and prevent tearing after long-term use.

[0029] The limiting structure includes an annular collar 10, which is coaxially rotatably mounted on the stud 2 (e.g., a bearing). A drive block 8 is fixedly mounted on the annular collar 10, preventing the drive block 8 from rotating synchronously with the stud 2. A limiting groove 11 is further formed on the drive block 8. Figure 1 As shown, the length direction of the limiting groove 11 is parallel to the axial direction of the stud 2. A limiting post 12 is slidably disposed within the limiting groove 11, and the limiting post 12 is fixedly connected to the mounting bracket 1. The setting of the limiting post 12 can prevent the drive block 8 from rotating synchronously when the stud 2 rotates. When the stud 2 rotates, the connection between the limiting post 12 and the limiting groove 11 can restrict the drive block 8 from rotating with the stud 2. When the stud 2 advances linearly, the stud 2 drives the annular collar 10 and the drive block 8 to move axially synchronously, causing the clamping block 7 to move towards each other. At this time, the limiting post 12 slides within the limiting groove 11, thus not interfering with the sliding of the drive block 8.

[0030] Furthermore, such as Figure 2 As shown, multiple balls 13 are rolled at the bottom end of the limiting post 12, and the limiting post 12 is connected to the limiting groove 11 through the balls 13. The arrangement of the balls 13 reduces the concentrated stress on the end of the limiting post 12 when it slides in the limiting groove 11, thereby making the sliding of the drive block 8 smoother.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, the mounting bracket 1 includes a vertical plate 14, with studs 2 screwed onto the vertical plate 14. A support plate 15 is fixedly mounted on the top of the vertical plate 14, and a limiting post 12 is fixedly mounted on the support plate 15. A fixed base can be added to the bottom of the vertical plate 14. The fixed base is fixed to the worktable of the processing equipment by bolts or welding to improve the overall structural stability.

[0032] In practice, the operator first places the diamond in the fitting area 6 of the flexible strap 4. By adjusting the position of the flexible strap 4 within the strip-shaped perforation 3, the fitting area 6 is made to fit tightly against the shape of the diamond. Subsequently, by rotating the stud 2, the stud 2 causes the flexible strap 4 to curl onto the stud 2, thereby reducing the size of the fitting area 6 and tightly wrapping the diamond. At the same time, the rotation of the stud 2 causes the drive block 8 to move along the axial direction of the stud 2, pushing the clamping blocks 7 closer together until the planar side of the clamping blocks 7 is stably clamped to the diamond by the flexible padding.

[0033] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
