Specific embodiments

[0023] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Referring to Figure 1 - Figure 5 , a diamond laser cutting machine disclosed by the present utility model includes a base 1. One side of the top of the base 1 is fixedly connected with a column 2. One side of the column 2 is connected with a laser 3 through a linear driver. A track groove 4 is opened at the top of the base 1 directly below the laser 3. Two groups of clamping assemblies 5 are symmetrically arranged in the track groove 4;

[0026] The clamping assembly 5 mainly consists of a sliding table 51, a pressure cylinder 52, a silica gel washer 53 and a negative pressure unit 54. The sliding table 51 is slidably arranged in the track groove 4. A circular groove 6 is opened at the top of the sliding table 51, and a pressure cylinder 52 is rotatably connected in the circular groove 6. A negative pressure unit 54 is arranged in the pressure cylinder 52. A silica gel washer 53 for attaching to the diamond is clamped at the opening of the pressure cylinder 52.

[0027] In this embodiment, since the surface of the diamond is not regular, additional pads are required to ensure the clamping stability of the diamond when clamping the diamond, making the laser cutting more accurate. And because the shapes of different diamonds are different, corresponding pads are required when clamping different diamonds, resulting in a cumbersome clamping process for the diamond and affecting the processing efficiency of the diamond.

[0028] Therefore, it can be observed that Figure 1 by opening a track groove 4 directly below the laser 3 and symmetrically arranging two groups of clamping assemblies 5 in the track groove 4, the diamond can be clamped by synchronously squeezing the diamond with the two clamping assemblies 5.

[0029] And by observing Figure 3 and Figure 4It can be found that by connecting a pressure cylinder 52 to the sliding table 51 and connecting a silica gel washer 53 to the opening of the pressure cylinder 52, when the clamping assembly 5 contacts the diamond, the flexible silica gel washer 53 can be used to fit the diamond, so that the diamond completely blocks the opening of the pressure cylinder 52. Subsequently, under the continuous extrusion of the sliding table 51, the negative pressure unit 54 located in the pressure cylinder 52 operates to generate negative pressure in the pressure cylinder 52, thereby sucking the diamond by negative pressure and fixing the diamond on the silica gel washer 53. The fixing stability of the diamond can be effectively improved, and the diamond will not shift due to loosening during laser cutting, thus effectively ensuring the cutting accuracy of the laser cutting machine.

[0030] By utilizing the flexible fitting effect of the silica gel washer 53, the clamping assembly 5 can suck the diamond by negative pressure for diamonds of different shapes, effectively ensuring the clamping effect of the clamping assembly 5 on the diamond. Thus, the clamping and positioning of the diamond are simpler and more convenient, greatly reducing the clamping difficulty of the diamond, and improving the practicality of the laser cutting machine.

[0031] In a further preferred embodiment of the present utility model, as Figure 4 and Figure 5 shown, a limiting portion 7 is formed by protruding at the opening of the inner side wall of the pressure cylinder 52, and a clamping groove 8 that fits with the limiting portion 7 is formed by concaveing on the outer side wall of the silica gel washer 53. Reinforcing ribs 9 for supporting the silica gel washer 53 are arranged on both sides of the clamping groove 8 inside the silica gel washer 53.

[0032] In this embodiment, due to the different uses of diamonds, their required sizes are also different. Therefore, when facing smaller diamonds, using a silica gel washer 53 with a large opening will result in the opening of the silica gel washer 53 being too large to effectively fit the diamond, and when encountering larger diamonds, using a silica gel washer 53 with a small opening will cause the opening to be too small, resulting in a small adsorption surface of the diamond and affecting the clamping stability.

[0033] Therefore, by observing Figure 4 and Figure 5 it can be found that a limiting portion 7 is provided at the opening of the inner side wall of the pressure cylinder 52, and a clamping groove 8 that fits with the limiting portion 7 is provided on the outer side wall of the silica gel washer 53, which can enable the silica gel washer 53 to freely switch styles according to the size of the diamond, further improving the practicality of the clamping assembly 5.

[0034] Since the silicone gasket 53 is made of flexible silicone, it will deform and generate gaps when the silicone gasket 53 is installed in the pressure cylinder 52, affecting the stability of negative pressure adsorption. Therefore, reinforcing ribs 9 are provided on both sides of the card slot 8 in the silicone gasket 53. The reinforcing ribs 9 support the silicone gasket 53, so that when the silicone gasket 53 is installed in the pressure cylinder 52, it can be ensured that it fits closely with the inner wall of the pressure cylinder 52, effectively ensuring the stability of the clamping assembly 5 for clamping the diamond.

[0035] In a further preferred embodiment of the present invention, as Figure 3 and Figure 4 shown, the negative pressure unit 54 includes a piston 541 and a sleeve 542. The inner side wall of the pressure cylinder 52 is fixedly connected with the sleeve 542. A piston 541 is slidably sleeved on the side of the sleeve 542 away from the opening of the pressure cylinder 52. The outer side wall of the piston 541 is in close contact with the inner side walls of the sleeve 542 and the pressure cylinder 52.

[0036] A chute 10 is formed on the outer side wall of the pressure cylinder 52. A connecting portion 11 protrudes from the outer side wall of the piston 541 at the position of the chute 10. The connecting portion 11 extends out of the chute 10 and is fixedly connected with a connecting ring 12. The connecting ring 12 is rotatably arranged in the circular groove 6.

[0037] In this embodiment, by providing a sleeve 542 in the pressure cylinder 52, and at the same time, a piston 541 is slidably sleeved on the side of the sleeve 542 away from the opening of the pressure cylinder 52, and the outer side wall of the piston 541 is in close contact with the inner side walls of the sleeve 542 and the pressure cylinder 52, when the piston 541 retracts into the sleeve 542, the space in the pressure cylinder 52 can be stretched, so that negative pressure is generated in the pressure cylinder 52, and suction force is generated at the opening of the pressure cylinder 52 to suck the diamond onto the silicone gasket 53.

[0038] By providing a connecting portion 11 on the outer side wall of the piston 541, and at the same time, a chute 10 for the sliding of the connecting portion 11 is formed on the outer side of the pressure cylinder 52, and a connecting ring 12 fixedly connected with the connecting portion 11 is slidably arranged on the outer side of the pressure cylinder 52, the sliding of the piston 541 can be adjusted by controlling the sliding of the connecting ring 12 outside the pressure cylinder 52, so that the pressure in the pressure cylinder 52 can be adjusted externally, making the pressure adjustment in the pressure cylinder 52 more convenient.

[0039] By rotatably connecting the connecting ring 12 with the circular groove 6 of the sliding table 51, when the sliding table 51 moves to clamp the diamond, the pressure applied during the sliding of the sliding table 51 can be used to drive the connecting ring 12 to slide on the pressure cylinder 52, so as to achieve the effect of automatically adsorbing the diamond after the clamping assembly 5 clamps the diamond, making the operation of the clamping assembly simpler.

[0040] In a further preferred embodiment of the present invention, asFigure 3 As shown in the figure, a rotating motor 13 is fixedly connected to the outer side wall of the sliding table 51. A gear 14 fixedly connected to the output shaft of the rotating motor 13 is rotatably arranged in the sliding table 51. A tooth groove 15 meshing with the gear 14 is formed in the outer side wall of the connecting ring 12.

[0041] In this embodiment, by arranging the rotating motor 13, the gear 14 in the sliding table 51 can be driven to rotate. And by machining a tooth groove 15 meshing with the gear 14 on the outer side wall of the connecting ring 12, when the gear 14 rotates, the connecting ring 12 can be driven to rotate, achieving the effect of controlling the rotation of the pressure cylinder 52.

[0042] And a diamond is clamped at the opening of the pressure cylinder 52. Therefore, when the rotating motor 13 operates, the diamond can be driven to rotate, so that when the laser cutting machine cuts the diamond, the cutting angle of the diamond can be adjusted according to requirements, making the processing of the diamond more efficient and further improving the practicability of the diamond laser cutting machine.

[0043] In a further preferred embodiment of the present utility model, as Figure 2 shown, a rotating shaft 16 is rotatably connected in the track groove 4. External threads are symmetrically machined at both ends of the rotating shaft 16 and are respectively threadedly connected to the two sliding tables 51. A driving motor 17 for driving the rotating shaft 16 to rotate is embedded in the base 1.

[0044] In this embodiment, by arranging the rotating shaft 16 and symmetrically arranging external threads at both ends of the rotating shaft 16, when the rotating shaft 16 rotates, the two clamping assemblies 5 can be controlled to approach or move away from each other synchronously, enabling the clamping assemblies 5 to better clamp the diamond.

[0045] And by arranging the driving motor 17, the rotating shaft 16 can be efficiently driven to rotate, making the efficiency of the clamping assemblies 5 clamping the diamond higher, thereby further improving the processing efficiency of the diamond.

[0046] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
