[0022] Please see Figures 1-3 A drilling device for diamond roller machining includes a worktable 1 and a connecting platform 4 slidably disposed on the top of the worktable 1. A first motor 5 is fixedly connected to the top front end of the connecting platform 4. The output shaft of the first motor 5 extends to the bottom of the connecting platform 4 and is fixedly connected to a drill bit 6. The first motor 5, the drill bit 6, and the top center of the worktable 1 are located on the same axis.

[0023] Furthermore, four guide grooves 101 are arranged in a circular array around the top of the workbench 1, and four arc-shaped clamps 10 are arranged in a circular array at the center of the top of the workbench 1. Each of the four arc-shaped clamps 10 is fixedly connected to an L-shaped connecting rod 11 on the side away from the center of the workbench 1. The other end of the four L-shaped connecting rods 11 extends to the bottom of the workbench 1 and slides between it and the inner wall of the guide groove 101. The movement path of the four L-shaped connecting rods 11 is from the periphery of the workbench 1 towards its center.

[0024] The top of the worktable 1 has four guide grooves 101 arranged in a circular array around its perimeter, with a central position for placing the diamond roller to be processed. Four arc-shaped clamping plates 10 are arranged in a circular array around the center of the top of the worktable 1. Each arc-shaped clamping plate 10 has an L-shaped connecting rod 11 fixedly connected to its side away from the center of the worktable 1. The L-shaped connecting rod 11 is connected to the bottom of the worktable 1 via the guide grooves 101, allowing them to slide along the guide grooves 101. One end of the L-shaped connecting rod 11 is connected to an arc-shaped clamping plate 10, and the other end extends through the guide grooves 101 to the bottom of the worktable 1, allowing the L-shaped connecting rod 11 to move from the perimeter of the worktable 1 towards its center, thereby adjusting the distance between the arc-shaped clamping plates 10 to accommodate diamond rollers of different sizes.

[0025] By applying pressure to the center simultaneously from four directions, the clamping force can be distributed more evenly, providing a better fixing effect and reducing vibration or displacement problems caused by insecure fixing. Thanks to the adjustable design, the distance between the arc-shaped clamping plates 10 can be changed by moving the L-shaped connecting rod 11, thus accommodating diamond rollers of various sizes, increasing the versatility and application range of the equipment.

[0026] Furthermore, a fixed plate 3 is provided on the upper rear side of the top of the workbench 1, and support legs 9 are fixedly connected to the four corners of the bottom of the workbench 1. A controller 21 for controlling the entire device is fixedly connected to the left end of the front surface of the workbench 1, and a slide rod 2 is fixedly connected to one side of the bottom of the fixed plate 3. The bottom of the slide rod 2 is fixedly connected to the rear side of the top of the workbench 1.

[0027] By installing support legs 9 at the four corners of the bottom of the worktable 1, the stability and robustness of the entire device are ensured, reducing the risk of vibration and displacement during processing. The fixing plate 3 is located above the rear side of the top of the worktable 1 and is connected to the slide rod 2, providing a stable mounting position for the entire moving assembly. The slide rod 2 allows the connecting platform 4 to slide on it, facilitating the adjustment of the position of the drill bit 6 relative to the diamond roller placed on the worktable 1. The connecting platform 4 is slidably mounted on the slide rod 2, and a first motor 5 is fixedly connected to its front top. The first motor 5 drives the drill bit 6 to perform drilling operations. The sliding design of the connecting platform 4 allows the drill bit 6 to be flexibly adjusted to accommodate workpieces of different sizes. The controller 21 is located at the left end of the front surface of the worktable 1 and is used to control the operation of the entire device, including starting / stopping the first motor 5 and moving the connecting platform 4.

[0028] Furthermore, a lifting threaded rod 7 is rotatably connected to the other side of the slide rod 2. The bottom of the lifting threaded rod 7 is rotatably connected to the rear top of the worktable 1. The top of the lifting threaded rod 7 extends to the top of the slide rod 2 and is fixedly connected to a second motor 8. The bottom of the second motor 8 is fixedly connected to the top of the slide rod 2.

[0029] The lifting threaded rod 7 allows the connecting table 4 to move up and down along it, thereby achieving precise adjustment of the height of the drill bit 6. The second motor 8 is fixed to the top of the slide rod 2 and directly drives the lifting threaded rod 7 to rotate, thereby driving the connecting table 4 and the drill bit 6 to move up and down.

[0030] Furthermore, the second motor 8 is provided with a protective cover 801. The bottom of the protective cover 801 is fixedly connected to the top of the slide rod 2. The lifting threaded rod 7 is threadedly connected to the connecting platform 4 on the lower surface of the slide rod 2. The inner wall of the other side of the connecting platform 4 is slidably connected to the slide rod 2.

[0031] The protective cover 801 covers the second motor 8 and is fixedly connected between the bottom and the top of the slide bar 2. This not only protects the second motor 8 from external dust, debris and other contaminants, but also improves the safety of the equipment and prevents operators from accidentally coming into contact with high-speed rotating parts.

[0032] Furthermore, a first horizontal threaded rod 12 is rotatably connected to both the front and rear ends of the bottom of the workbench 1. The first horizontal threaded rod 12 is vertically arranged between the workbench 1 and the two first horizontal threaded rods 12 are rotatably connected to the front and rear sides of the bottom of the workbench 1 respectively at one end away from each other. A third motor 13 is fixedly connected to one end of the front first horizontal threaded rod 12.

[0033] The third motor 13 is installed at one end of the first horizontal threaded rod 12 at the front end, providing power to rotate the first horizontal threaded rod 12, thereby realizing the automatic adjustment of the position of the L-shaped connecting rod 11.

[0034] Furthermore, a worm gear 14 is fixedly connected to one end of each of the two horizontal threaded rods 12, and a worm wheel 17 is meshed with the bottom of the worm gear 14. A threaded block 15 is threadedly connected to the surface of each of the two horizontal threaded rods 12. The tops of the two threaded blocks 15 are fixedly connected to the bottoms of the two L-shaped connecting rods 11 at the front and rear of the top of the worktable 1, respectively. A horizontal limiting rod 16 is fixedly connected to the bottom of the worktable 1 and is perpendicular to the worktable 1.

[0035] Two horizontal threaded rods 12 are threadedly connected to threaded blocks 15. As the horizontal threaded rods 12 rotate, the threaded blocks 15 move along the threaded rods, causing the L-shaped connecting rods 11 connected to them to adjust their positions. A horizontal limit rod 16 is fixedly connected to the bottom of the worktable 1, which is perpendicular to the worktable 1 and provides guidance for the threaded blocks 15, ensuring that they move in a straight line without deviating from the track.

[0036] Furthermore, the first horizontal limiting rod 16 is located below the two first horizontal threaded rods 12, and the first horizontal limiting rod 16 is slidably connected to the two first threaded blocks 15. The second horizontal threaded rod 18 is fixedly connected to the inner wall of the worm gear 17. The second horizontal threaded rod 18 is arranged parallel to the bottom of the worktable 1, and the left and right ends of the second horizontal threaded rod 18 are rotatably connected to the left and right sides of the bottom of the worktable 1, respectively. The second horizontal threaded rod 18 is located below the first horizontal threaded rod 12.

[0037] Furthermore, threaded blocks 19 are threadedly connected to both sides of the surface of the second horizontal threaded rod 18. The tops of the two threaded blocks 19 are fixedly connected to the bottoms of the two L-shaped connecting rods 11 on the left and right sides of the top of the workbench 1, respectively. A second horizontal limiting rod 20 is fixedly connected to the bottom of the workbench 1. The second horizontal limiting rod 20 is located below the second horizontal threaded rod 18 and is slidably connected to the two threaded blocks 19.

[0038] The second horizontal threaded rod 18 has threaded blocks 19 on both sides of its surface. The top of each threaded block 19 is fixedly connected to the bottom of the L-shaped connecting rods 11 on the left and right sides of the top of the worktable 1. When the second horizontal threaded rod 18 rotates, the threaded blocks 19 will drive the L-shaped connecting rods 11 to move left and right. The second horizontal limit rod 20 is located below the second horizontal threaded rod 18, fixedly connected to the bottom of the worktable 1, and slidably connected to the two threaded blocks 19 to ensure that the threaded blocks 19 remain stable and move in a straight line during movement.

[0039] First, the diamond roller to be processed is placed at the center of the worktable 1. The third motor 13 is started via controller 21, causing the first horizontal threaded rod 12 to rotate. This rotates the first threaded block 15, which in turn slides along the first horizontal limit rod 16, adjusting the position of the L-shaped connecting rod 11 in the front-to-back direction to ensure that the arc-shaped clamping plate 10 can firmly clamp the roller. Simultaneously, the rotation of the first horizontal threaded rod 12 is transmitted to the second horizontal threaded rod 18 via the worm gear 14 and worm wheel 17, causing it to rotate. This rotates the second threaded block 19, which slides along the second horizontal limit rod 20, adjusting the position of the L-shaped connecting rod 11 in the left-to-right direction to further securely clamp the roller.

[0040] After clamping is complete, the second motor 8 is started, causing the lifting threaded rod 7 to rotate and move the connecting table 4 downwards along the slide rod 2 until the drill bit 6 contacts the surface of the diamond roller. Next, the first motor 5 is started, driving the drill bit 6 to perform drilling. During drilling, the height of the drill bit 6 can be precisely adjusted as needed to accommodate different drilling depth requirements. After processing is complete, the second motor 8 can be reversed via the controller 21 to raise the drill bit 6 away from the diamond roller surface, releasing the clamp, removing the processed roller, and preparing for the next round of processing.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
