Description

Technical Field

[0001] This utility model relates to the field of industrial equipment, and in particular to a diamond cutting fixture. Background Technology

[0002] In the field of superhard materials processing equipment, diamond plays a vital role in many high-end applications due to its excellent physical properties. Crystal-oriented cutting of diamond blanks is a crucial step in the processing, especially in precision laser cutting scenarios, where extremely high requirements are placed on cutting accuracy and angle control.

[0003] Currently, traditional jigs have many limitations in the cutting and processing of diamond blanks. On the one hand, traditional jigs struggle to achieve precise angle adjustments, failing to meet the high-precision control requirements for cutting angles in the directional cutting of diamond crystals. This results in the cut products failing to meet the expected precision standards, affecting subsequent processing and product performance. On the other hand, traditional jigs often use adhesive to bond the diamond blanks during processing. This method not only generates pollution but also makes it difficult to ensure the uniformity of the overall thickness of the blank during processing, leading to unstable product quality. Furthermore, the adhesive bonding and subsequent cleaning processes increase the complexity of the processing flow, reduce work efficiency, and cannot meet the requirements of large-scale, high-efficiency production.

[0004] Therefore, there is an urgent need to develop a new diamond cutting fixture. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Reference Figure 1 and Figure 2This utility model provides an embodiment of a diamond cutting fixture, comprising a diamond adsorption part 1, a substrate 2, a base 3, and a rotating fixing block 4. The rotating fixing blocks 4 are fixedly mounted in pairs on the base 3, and the pairs of rotating fixing blocks 4 are respectively disposed on both sides of one end of the substrate 2. One end of the substrate 2 is rotatably connected to the rotating fixing block 4 via a pivot 41. The substrate 2 is located above the base 3 and has a gap with the base 3. The other end of the substrate 2 can rotate around the pivot 41. An angle adjustment mechanism is provided at the other end of the substrate 2 to adjust the rotation angle of the other end of the substrate 2. The diamond adsorption part 1 is disposed on the upper surface of the substrate 2, and the diamond adsorption part 1 rotates synchronously with the substrate 2.

[0034] In this embodiment, two rotating fixing blocks 4 are respectively fixedly installed on the base 3 by bolts. Shaft holes are provided on both sides of the end of the substrate 2 closest to the rotating fixing blocks. A pivot 41 passes through these shaft holes and the corresponding shaft holes of the rotating fixing blocks 4 on both sides, realizing the rotatable connection between the substrate 2 and the rotating fixing blocks 4. The two ends of the pivot 41 can be limited by retaining rings or nuts. The substrate 2 is located directly above the base 3, with a certain gap between them to facilitate the rotational adjustment of the substrate 2. The diamond adsorption part 1 is detachably fixed to the upper surface of the substrate 2 by bolts or positioning pins. The other end of the substrate 2 (i.e., the end away from the pivot 41) is a free end, which can rotate around the pivot 41. The plane of rotation is a vertical plane perpendicular to the axis of the pivot 41, thereby adjusting the overall tilt angle of the substrate 2, which in turn causes the diamond adsorption part 1 to tilt, thus adjusting the tilt angle of the diamond adsorbed on it.

[0035] In the specific operation process, the diamond to be cut is adsorbed onto the adsorption surface of the diamond adsorption part 1. Through the angle adjustment mechanism, the substrate 2 is rotated around the pivot 41 as the rotation center. The other end of the substrate 2 rotates up or down under the action of the angle adjustment mechanism, which drives the diamond adsorption part 1 and the diamond to be cut to rotate synchronously and maintain at the target angle.

[0036] The diamond cutting fixture of this embodiment, through the cooperation of the rotating fixing block 4 and the pivot 41, enables the substrate 2 to rotate stably around the pivot 41 in a vertical plane. With the cooperation of the angle adjustment mechanism at the other end of the substrate 2, the tilt angle of the substrate 2 in the vertical plane can be accurately controlled, thereby achieving accurate control of the cutting angle of the diamond in the vertical plane. At the same time, the diamond to be cut is adsorbed by the diamond adsorption part 1, eliminating the need for glue bonding, avoiding the pollution caused by glue, simplifying the processing flow, improving work efficiency, and meeting the needs of large-scale high-efficiency production.

[0037] In one specific embodiment, refer to Figure 2The angle adjustment mechanism includes an elastic component 5 and an adjusting bolt 6;

[0038] The elastic component 5 is disposed between the other end of the substrate 2 and the base 3, with one end of the elastic component 5 connected to the base 3 and the other end of the elastic component 5 connected to the substrate 2.

[0039] The other end of the substrate 2 is provided with a stepped hole 202. The adjusting bolt 6 includes a screw 601 and a nut 602. The screw 601 passes through the through hole of the stepped hole 202. The lower end of the screw 601 abuts against the base 3. The nut 602 is locked in the stepped surface of the stepped hole 202. By rotating the nut 602, the substrate 2 is driven to rotate around the pivot 41, so that the elastic component is compressed or rebounded.

[0040] In this embodiment, the elastic component 5 is a compression spring, with its lower end embedded and fixed in a pre-set spring mounting groove on the upper surface of the base 3; the upper end of the elastic component 5 abuts against a spring positioning groove at a corresponding position on the lower surface of the substrate 2. A stepped hole 202 is provided at the center of the other end (i.e., the free end) of the substrate 2. The stepped hole 202 consists of two parts: the upper part is a countersunk hole with a larger diameter, and the lower part is a through hole with a diameter matching the screw 601 of the adjusting bolt 6. The adjusting bolt 6 consists of a screw 601 and a nut 602, wherein the screw 601 passes through the through hole of the stepped hole 202, and its lower end face abuts against the upper surface of the base 3; the outer diameter of the nut 602 is larger than the diameter of the through hole, and it is locked onto the stepped surface of the stepped hole 202.

[0041] In specific operation, when it is necessary to adjust the tilt angle of the substrate 2, rotate the nut 602 of the adjusting bolt 6: if the nut 602 is rotated clockwise, the nut 602 moves downward along the screw 601 and pushes the other end of the substrate 2 to rotate downward. At this time, the elastic component 5 is compressed by the pressure of the substrate 2; if the nut 602 is rotated counterclockwise, the nut 602 moves upward along the screw 601, and the other end of the substrate 2 rotates upward under the rebound force of the elastic component 5, and the elastic component 5 gradually extends. By controlling the rotation of the nut 602, the rotation angle of the substrate 2 around the pivot 41 can be accurately adjusted, and the elastic force of the elastic component 5 and the abutting force of the adjusting bolt 6 are balanced to keep the substrate 2 stably at the target angle.

[0042] In one specific embodiment, refer to Figure 2The diamond adsorption unit 1 includes an adsorption body 101 and a vacuum interface 102. The adsorption body 101 has an internal air channel. The vacuum interface 102 is located on the side wall or top of the adsorption body 101 and communicates with the internal air channel. The adsorption surface 103 of the adsorption body 101 has a plurality of adsorption through holes 104. The adsorption through holes 104 communicate with the vacuum interface 102 through the internal air channel. The vacuum interface 102 is used to connect to an external vacuum source. The adsorption surface 101 is used to adsorb diamond.

[0043] In this embodiment, the adsorption body 101 is made of high-strength aluminum alloy or stainless steel into a rectangular block structure. A straight internal air channel is formed inside the adsorption body 101, with one end closed and the other end connected to a vacuum interface 102. The vacuum interface 102 can be a standard threaded interface, located on the side wall or top of the adsorption body 101. Its inner port directly communicates with one end of the internal air channel, while its outer port is used to connect to an external vacuum pipeline. One vertical side of the adsorption body 101 is a flat adsorption surface 103. Several adsorption through holes 104 are evenly formed on the adsorption surface 103. These adsorption through holes 104 are arranged along the length of the internal air channel, with a diameter of several millimeters. Each adsorption through hole 104 penetrates to the side wall of the internal air channel and is directly connected to it.

[0044] In the specific operation, an external vacuum source (such as a vacuum pump) is connected to the vacuum interface 102. After the vacuum source is activated, the air in the internal air passage and adsorption through-hole 104 is extracted, forming a negative pressure environment. When the diamond to be cut is placed on the adsorption surface 103, the diamond is tightly adsorbed onto the adsorption surface 103, achieving stable clamping. The magnitude of the adsorption force can be controlled by adjusting the power of the vacuum source. Vacuum adsorption effectively avoids the pollution problems caused by traditional glue bonding. At the same time, vacuum adsorption is convenient to operate, with fast clamping and disassembly speeds, significantly shortening auxiliary time and improving processing efficiency, making it suitable for large-scale production scenarios.

[0045] In one specific embodiment, refer to Figure 3 The bottom of the adsorption body 101 has a connection hole 106, and the substrate 2 has a mounting positioning groove 203. A connecting post 204 is fixed in the mounting positioning groove 203. The connecting post 204 is inserted into the connection hole 106, and the bottom of the adsorption body 101 is embedded in the mounting positioning groove 203. The substrate 2 and the diamond adsorption part 1 are detachably connected by the insertion of the connecting post 204 into the connection hole 106.

[0046] In this embodiment, a mounting positioning groove 203 matching the bottom contour of the adsorption body 101 is formed on the upper surface of the substrate 2 corresponding to the mounting position of the adsorption body 101. The depth of the mounting positioning groove 203 is several millimeters to tens of millimeters. A connecting post 204 is fixed at the center of the mounting positioning groove 203. The connecting post 204 is fixed to the substrate 2 by integral molding or welding. The shape and size of the connecting post 204 match those of the connecting hole 106.

[0047] During the specific assembly process, the bottom of the adsorption body 101 is aligned with the mounting positioning groove 203, and the connecting hole 106 is inserted into the connecting post 204. The body is lowered until the bottom of the adsorption body 101 is completely embedded in the mounting positioning groove 203. At this time, the bottom surface of the adsorption body 101 is in close contact with the bottom of the mounting positioning groove 203, which realizes the quick positioning and detachable connection between the adsorption body 101 and the substrate 2. This is beneficial for quickly replacing adsorption bodies 101 of different specifications according to the size of the diamond blank, and improves the versatility of the fixture.

[0048] In one specific embodiment, refer to Figure 4 It also includes a base 7, on which the base 3 is movably supported; limiting blocks 8 are respectively provided on the adjacent two sides of the base 7, and each limiting block 8 abuts against the side of the base 3 for limitation; locking mechanisms 9 are respectively provided on the other two sides of the base 7, and each locking mechanism 9 abuts against the side of the base 3.

[0049] In this embodiment, the base 7 is a rectangular flat plate structure made of cast iron or cast aluminum. Several threaded holes are formed on the side edges of the base 7 for mounting the limiting blocks 8 and the locking mechanisms 9. During assembly, the base 3 is first placed on the upper surface of the base 7, with its two sides respectively abutting against the corresponding limiting blocks 8. Then, the locking mechanisms 9 are adjusted so that the two locking mechanisms 9 respectively press against the other two sides of the base 3 until the base 3 is firmly clamped.

[0050] In one specific embodiment, refer to Figure 4 The locking mechanism 9 includes a locking knob 905, a transmission screw 906, and a handle fixing block 907. The handle fixing block 907 is fixed to the side of the base 7. The locking knob 905 is connected to one end of the transmission screw 906, and the other end of the transmission screw 906 passes through the handle fixing block 907. When the locking knob 905 is rotated, the transmission screw 906 moves toward the base 3, and the end of the transmission screw 906 presses against the side of the base 3 to achieve a tight fit.

[0051] In this embodiment, two handle fixing blocks 907 are vertically fixed to the two side edges of the base 7 by bolts. A threaded through hole matching the transmission screw 906 is provided in the middle of the handle fixing block 907. One end of the transmission screw 906 is connected to the locking knob 905, and the other end passes through the threaded through hole of the handle fixing block 907, abutting against the side of the base 3. The outer circumference of the locking knob 905 is provided with knurled anti-slip texture for easy manual application of force.

[0052] In one specific embodiment, refer to Figure 4 The limiting block 8 has a limiting boss 802 on the side facing the base 3, and the base 3 has a limiting groove 303 on the corresponding side. The limiting boss is embedded in the limiting groove to form the abutment limiting. The limiting block 8 has an L-shaped structure. The vertical surface is fixedly connected to the threaded hole of the base 7 by screws, and the horizontal surface forms the limiting boss 802, which fits and abuts against the limiting groove 303 of the base 3.

[0053] In one specific embodiment, refer to Figure 5 and Figure 6 The system also includes a horizontal rotating platform 10, which is connected to the bottom of the base 7. A handle 1006 is provided on one side of the horizontal rotating platform 10. The bottom of the base 7 is fixedly connected to the horizontal rotating platform 10 by bolts. The operator drives the horizontal rotating platform 10 to rotate by holding the handle 1006, thereby adjusting the rotation angle of the diamond adsorption part 1 in the horizontal plane, and thus adjusting the rotation angle of the diamond to be cut in the horizontal plane. The horizontal rotating platform 10 and the tilt adjustment of the substrate 2 in the vertical plane cooperate to jointly construct a multi-dimensional control system for the diamond cutting angle.

[0054] The horizontal rotating table 10 includes a fixed base 1002 and a rotating disk 1003. The rotating disk 1003 is fixedly connected to the bottom of the base 7. The lower surface of the rotating disk 1003 has an annular protrusion 1004, and the fixed base 1002 has a corresponding annular groove 1005. The rotating disk 1003 and the fixed base 1002 are assembled through the annular protrusion 1004 and the annular groove 1005. A handle 1006 is provided on one side of the rotating disk 1003, allowing the rotating disk 1003 to rotate relative to the fixed base. The rotating disk 1003 is fixedly connected to the bottom of the base 7 by bolts. The rotating disk 1003 has a circular structure, and the cross-sectional shape of the annular groove 1005 matches the annular protrusion 1004. The handle 1006 is located on one side of the rotating disk 1003. When a large-range angle adjustment of the horizontal plane is required, the operator holds the handle 1006 and pushes the rotating disk 1003 until it approaches the target angle, at which point the pushing stops.

[0055] In one specific embodiment, refer to Figure 5 and Figure 6A horizontal rotation adjustment knob 11 is also provided on one side of the horizontal rotary table 10. The horizontal rotation adjustment knob 11 includes an adjustment pin 1101 and fine adjustment knobs 1102 located on both sides of the adjustment pin 1101. The adjustment pin 1101 passes through the side wall of the fixed base 1002 and abuts against the rotating disk 1003. When the fine adjustment knobs 1102 are rotated, the rotating disk 1003 is rotated. When a small angle adjustment of the horizontal plane of the rotating disk 1003 is required, the fine adjustment knobs 1102 are rotated until the target angle is reached. This structure, in conjunction with the wide-range rotation function of the handle 1006 of the horizontal rotary table 10, completes the coordination of coarse and fine adjustment of the horizontal plane rotation angle, further realizing the accurate adjustment of the diamond crystal directional cutting angle.

[0056] When using the diamond cutting fixture of this embodiment for diamond cutting, the base 7 is placed on the worktable of the processing equipment and fixed. Then, the base 3 is placed on the base 7, so that the limiting grooves 303 on the front and left sides of the base 3 are aligned with the limiting protrusions 802 of the limiting block 8. Then, the locking knobs 905 of the locking mechanisms 9 on the rear and right sides of the base 7 are rotated, so that the transmission screw 906 pushes the top block 903 against the side of the base 3, and clamps it firmly. Next, the connecting hole 106 of the diamond adsorption part 1 is aligned with the connecting post 204 in the mounting positioning groove 203 of the substrate 2, so that the bottom of the adsorption body 101 is embedded in the positioning groove. Then, the diamond to be cut is placed on the adsorption surface 103 of the adsorption body 101, and an external vacuum source is connected through the vacuum interface 102. The equipment is started to create a negative pressure between the internal air passage and the adsorption through hole 104, so that the diamond to be cut is tightly adsorbed. When adjusting the vertical plane angle, to increase the tilt angle of substrate 2 (diamond tilting upwards), turn the nut 602 of the adjusting bolt 6 counterclockwise. The nut moves upwards along the screw 601, and the free end of substrate 2 rotates upwards under the rebound action of the elastic component 5, causing the diamond to tilt. To decrease the tilt angle (diamond tilting downwards), turn the nut 602 clockwise, pushing the free end of substrate 2 downwards and compressing the elastic component 5 until the target angle is achieved in the vertical plane. For horizontal plane angle adjustment, for large-range coarse adjustments, hold the handle 1006 on one side of the rotating disk 1003 of the horizontal rotating table 10 and push the rotating disk to rotate relative to the fixed seat 1002. For fine adjustments, rotate the fine adjustment knob 1102 to the target angle. After the diamond cutting process is completed, turn off the vacuum source to release the negative pressure on the adsorption surface 103, remove the cut diamond workpiece, and reset all components.
