[0025] 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.

[0026] like Figures 1 to 4 As shown, this utility model provides a grinding device for processing synthetic diamonds, including a support frame 1 and a clamping assembly 2 located around the support frame 1. A diamond body 7 is pressed against the inside of the clamping assembly 2, and the diamond body 7 rotates on the surface of the support frame 1.

[0027] The support frame 1 includes a motor 3. The output end of the motor 3 is fixedly connected to a transmission rod 31. The surface of the transmission rod 31 is fitted with a coarse grinding block 32 and a fine grinding block 33. The surfaces of the coarse grinding block 32 and the fine grinding block 33 are threadedly connected with locking blocks 321. The other end of the locking blocks 321 abuts against the surface of the transmission rod 31. The support frame 1 has several sets of equidistant support plates on the left and right sides. The support plates are all provided with round holes and grooves. The coarse grinding block 32 and the fine grinding block 33 slide inside the round holes and grooves on the surface of the support plates of the support frame 1.

[0028] In existing technologies, a single grinding device is typically used to grind the diamond body 7. During the grinding process, coarse grinding and fine grinding are used alternately. However, in practice, it is necessary to stop work for a long time to disassemble and reassemble the grinding device, which takes a lot of time. The improved technology uses a locking block 321 to assemble the coarse grinding block 32 and the fine grinding block 33, which reduces the assembly time and allows for the addition of multiple grinding devices, increasing adaptability.

[0029] Specifically, the top of the clamping assembly 2 is fixedly connected to the base 21 by bolts, the top of the base 21 is fixedly connected to the L-shaped frame 22, the inside of the L-shaped frame 22 is fixedly connected to the threaded rod 23, the surface of the threaded rod 23 is fitted with the top cover 26, the bottom end of the top cover 26 is attached to the top of the L-shaped frame 22, the L-shaped frame 22 is set in an L-shape, the surface of the threaded rod 23 is threadedly connected to the nut 24, the bottom end of the nut 24 is pressed against the bottom end of the top cover 26, by placing the diamond body 7 inside the clamp 25 to limit the diamond body 7, and a drive device is added to the top of the L-shaped frame 22 to control the rotation of the diamond body 7 inside the clamp 25. The addition of an adjustable top cover 26 to the top of the L-shaped frame 22 can be used to accommodate different diamond bodies 7, increasing adaptability.

[0030] Furthermore, a monitoring device 35 is fixedly connected to the side of the support frame 1. The monitoring device 35 is used to detect and record the position of the diamond body 7 protruding on the surface of the fixture 25. The protruding position is then used for subsequent edge grinding to prevent over-grinding or incomplete edge grinding of the diamond body 7 by the coarse grinding block 32 or the fine grinding block 33. A scraper 6 is fixedly connected to the support plate on the surface of the support frame 1 of the fixture 25 to scrape off the metal chips on the surface of the coarse grinding block 32 and the fine grinding block 33 used for edge grinding, so as to prevent the surface of the diamond body 7 from being scratched by the metal chips.

[0031] Furthermore, clamps 25 are fixedly connected to the surfaces of the L-shaped frame 22 and the top cover 26. The clamps 25 are made of elastic material, and the diamond body 7 is positioned between the two sets of clamps 25.

[0032] It is worth noting that a collection box 4 is fixedly connected to the surface of the support frame 1. The collection box 4 is set as a collection groove with the opening facing upward. The collection box 4 is made of plastic to prevent the magnetic counterweight 5 from adhering to the inside of the collection box 4. The inside of the collection box 4 is used to place several sets of counterweights 5.

[0033] It is worth noting that the counterweight 5 is attached to the surface of the coarse grinding block 32 and the fine grinding block 33 to balance the coarse grinding block 32 and the fine grinding block 33 and maintain the balance of the coarse grinding block 32 and the fine grinding block 33 when grinding the edge.

[0034] It is worth mentioning that the surface of the diamond body 7 is larger than the surface of the clamp 25, and the grinding area is the position where the surface of the diamond body 7 is larger than the surface of the clamp 25. The surface of the coarse grinding block 32 or the fine grinding block 33 is used to rub the above-mentioned protruding position.

[0035] It is worth emphasizing that the support frame 1 is equipped with a moving module 34 at both the bottom and top. The moving module 34 is used to control the movement of the grinding device, so that the grinding device can move closer to the diamond body 7, which is convenient for adjusting the grinding quality.

[0036] The structure, including the electric motor, is existing technology and will not be described further. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described further. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0037] Working principle:

[0038] The first step is to clamp the diamond body 7; rotate the nut 24 on the surface of the upper cover 26 counterclockwise from the surface of the threaded rod 23, slide the upper cover 26 along the threaded rod 23 inside the L-shaped frame 22 to the top, control the clamp 25 located at the bottom of the upper cover 26 to separate from another set of clamps 25, place the diamond body 7 between the two sets of clamps 25, and fix and limit the diamond body 7, waiting for the edge to be ground;

[0039] According to the shape of the edge to be ground on the surface of the diamond body 7, select a suitable grinding head, slide the coarse grinding block 32 and the fine grinding block 33 onto the surface of the transmission rod 31 respectively, and lock them to the transmission rod 31 respectively through the locking block 321, so as to fix the fine grinding block 33 and the coarse grinding block 32 on the surface of the transmission rod 31.

[0040] In the edge grinding stage, the relevant edge grinding device is moved to a position close to the surface of the diamond body 7 via the moving module 34, and the motor 3 is started. The motor 3 drives the transmission rod 31 to rotate, which in turn drives the coarse grinding block 32 and the fine grinding block 33 to rotate, thus grinding the edge of the diamond body 7. The monitoring device 35 is used to monitor the position of the diamond body 7 other than the overlap point with the fixture 25 to prevent over-grinding. During the edge grinding process, metal shavings will adhere to the surface of the coarse grinding block 32. The scraper 6 is used to scrape away the metal shavings.

[0041] When fine edge grinding is required, the motor 3 is turned off and the relevant edge grinding device is moved to the left. The locking blocks 321 on the surfaces of the coarse grinding block 32 and the fine grinding block 33 are released from the surface of the transmission rod 31, and slide down from the circular slot on the surface of the support layer of the support frame 1. During the sliding process, the fine grinding block 33 contacts the surface of the diamond body 7 and is used to grind the diamond body 7. Through continuous edge grinding, the diamond body 7 is ground to the required shape.
