[0003] Therefore, we propose a fixture for diamond grinding to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for diamond grinding, which solves the problem that in the prior art, diamond tools with uneven surfaces are difficult to securely fix when using traditional fixtures for positioning and clamping, causing the tools to shake during the grinding process, thus affecting the processing quality. This problem restricts the improvement of the stability and precision of the grinding operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixture for grinding diamond abrasives includes a processing table, a support base fixedly mounted on the top of the processing table, a rotating component fixedly mounted on the top of the support base, and a positioning component fixedly mounted on the top of the rotating component. The positioning assembly includes a platform, support plates, support frames, a first cylinder, a second cylinder, and a clamping assembly. Support plates are symmetrically fixedly installed on both sides of the top of the platform. Support frames are fixedly installed on both the front and rear sides of the platform. A first cylinder is fixedly installed on the side of each of the two support plates furthest from each other. A first drive rod is fixedly connected to the output end of each of the two first drive rods. A clamping assembly is fixedly installed on the adjacent end of each of the two first drive rods. A second cylinder is fixedly installed on the side of each of the two support frames furthest from each other. A second drive rod is fixedly connected to the output end of each of the two second drive rods. A clamping assembly is fixedly installed on the adjacent end of each of the two second drive rods. The clamping assembly includes a moving plate, telescopic rods, a return spring, and rubber clamps. The moving plate is fixedly installed on one end of either the first or second drive rod, and several telescopic rods are fixedly installed on the surface of the moving plate. A rubber clamp is fixedly installed on the end of each telescopic rod furthest from the moving plate, and a return spring is sleeved on the outside of each telescopic rod, located between the rubber clamp and the moving plate.

[0006] Preferably, the rotating assembly includes a drive motor, a drive shaft, and a rotating base. The support base has a movable groove inside, and the drive motor is fixedly installed at the bottom of the movable groove. The rotating base is rotatably disposed inside the support base, and the top output end of the drive motor is fixedly connected to the bottom of the rotating base through the drive shaft.

[0007] Preferably, a fixing frame is fixedly installed on the top of the support base, and the platform is fixedly installed on the top of the fixing frame.

[0008] Preferably, the support base has a first connecting block fixedly installed on both the front and rear sides of its bottom, and the two first connecting blocks are rotatably connected by a connecting frame via a damping bearing.

[0009] Preferably, a second connecting block is provided on both sides of the bottom end of the connecting frame, and the bottom end of the connecting frame is rotatably connected between the two second connecting blocks through a damping bearing.

[0010] Preferably, the bottom of the connecting frame is also provided with a base, which is fixedly installed on the bottom of the two second connecting blocks.

[0011] This utility model has at least the following beneficial effects: The clamping assembly with an elastic buffer structure is driven by the first and second cylinders. The telescopic rod, return spring and rubber chuck can adapt to the unevenness of the diamond grinding wheel surface and achieve tight contact at multiple points. This solves the problem of unstable fixation caused by poor surface adaptability of traditional clamps, effectively eliminates the shaking phenomenon during the grinding process and significantly improves the stability of processing quality.

[0012] This utility model also has the following beneficial effects: The rotating assembly enables the grinding wheel to rotate 360° horizontally. Combined with the damping bearing structure between the support base and the connecting frame, and between the connecting frame and the base, the grinding wheel's tilt angle can be flexibly adjusted from 0-30° left and right, and front and back, to meet multi-directional and multi-angle grinding needs, greatly improving operational flexibility. The base is double-fixed by anti-slip rubber pads and expansion bolts, and supported by a high-strength fixing frame, ensuring stable operation of the overall structure during high-speed grinding, further guaranteeing processing accuracy. The rubber chuck is made of soft material with a certain amount of friction, which not only enhances the clamping firmness but also avoids damage to the surface of the diamond grinding wheel, achieving protective clamping. The modular component design facilitates later maintenance and component replacement, reduces equipment operation and maintenance costs, and improves the overall efficiency and reliability of diamond grinding wheel processing.

The positioning assembly includes a platform 3, support plates 4, support frames 5, a first cylinder 6, a second cylinder 7, and a clamping assembly. Support plates 4 are symmetrically fixedly installed on both sides of the top of the platform 3. Support frames 5 are fixedly installed on both the front and rear sides of the platform 3. A first cylinder 6 is fixedly installed on the side of each support plate 4 that is furthest from the other. A first drive rod 20 is fixedly connected to the output end of each of the two first drive rods 20. A clamping assembly is fixedly installed on the adjacent end of each of the two first drive rods 20. A second cylinder 7 is fixedly installed on the side of each support frame 5 that is furthest from the other. A clamping assembly is fixedly installed on the output end of each of the two second cylinders 7. A second drive rod 21 is fixedly connected to the first drive rod 20 or the second drive rod 21. A clamp assembly is fixedly installed at one adjacent end of each of the two second drive rods 21.

The movable plate 8 is fixedly installed at one end of the first drive rod 20 or the second drive rod 21, and several telescopic rods 9 are fixedly installed on the surface of the movable plate 8. A rubber chuck 11 is fixedly installed at the end of each telescopic rod 9 away from the movable plate 8, and a return spring 10 is sleeved on the outside of each telescopic rod 9. The return spring 10 is located between the rubber chuck 11 and the movable plate 8.

[0018] Furthermore, the rotating assembly includes a drive motor 12, a drive shaft 13, and a rotating seat 14. The support base 2 has a movable groove inside, and the drive motor 12 is fixedly installed at the bottom of the movable groove. The rotating seat 14 is rotatably disposed inside the support base 2. The top output end of the drive motor 12 is fixedly connected to the bottom of the rotating seat 14 through the drive shaft 13. Specifically, when the drive motor 12 is working, it can drive the rotating seat 14 to rotate horizontally through the drive shaft 13, thereby realizing the angle adjustment of the positioning assembly and the diamond grinding wheel held, and meeting the grinding needs in different directions.

[0019] Furthermore, a fixed frame 15 is fixedly installed on the top of the support base 2, and the platform 3 is fixedly installed on the top of the fixed frame 15. Specifically, the fixed frame 15 is made of high-strength alloy material, and its bottom is bolted to the top surface of the rotating base 14, and its top is welded to the bottom surface of the platform 3 to ensure that the positioning components are installed stably.

[0020] Furthermore, the support base 2 has a first connecting block 16 fixedly installed on both the front and rear sides of the bottom, and the two first connecting blocks 16 are connected to the connecting frame 17 by a damping bearing for lateral rotation. Specifically, the damping bearing allows the support base 2 to tilt in the left and right directions relative to the connecting frame 17, with an tilt angle range of 0-30°, and can stay stably at any angle position.

[0021] Furthermore, the bottom of the connecting frame 17 is provided with a second connecting block 18 on both sides. The bottom of the connecting frame 17 is rotatably connected between the two second connecting blocks 18 through a damping bearing. Specifically, the damping bearing, in conjunction with the damping bearing at the first connecting block 16, can realize multi-directional angle adjustment of the support base 2 and the positioning component. The front and rear tilt angle is also 0-30°, which improves the flexibility of the grinding operation.

[0022] Furthermore, the bottom of the connecting frame 17 is also provided with a base 19, which is fixedly installed on the bottom of the two second connecting blocks 18. Specifically, the bottom of the base 19 is provided with an anti-slip rubber pad to increase the friction with the processing table 1, and the base 19 is fixedly connected to the processing table 1 by expansion bolts to ensure the stable operation of the overall structure.

[0023] In summary, this fixture for diamond grinding is designed with the characteristics and processing requirements of diamond grinding tools in mind. Its positioning assembly, driven by two sets of first cylinders 6 and two sets of second cylinders 7 from four directions (left, right, front, and back), along with an elastic buffer structure consisting of a telescopic rod 9, a return spring 10, and rubber chucks 11, adapts to uneven surfaces of the grinding tool. Multi-point contact ensures secure clamping, effectively avoiding the loosening and wobbling problems caused by poor surface adaptability in traditional fixtures. The rotating assembly, driven by the drive motor 12 and drive shaft 13, allows for 360° horizontal rotation of the positioning assembly and the grinding tool, meeting grinding requirements from different angles. The damping bearing connection structure between the support base 2 and the connecting frame 17, and between the connecting frame 17 and the base 19, allows for flexible adjustment of the grinding tool's left-right and front-back tilt angles (arbitrarily fixed within the range of 0-30°), significantly improving the flexibility of the processing operation. The base 19 is double-fixed by anti-slip rubber pads and expansion bolts, combined with the support of the high-strength fixing frame 15, ensuring stable operation of the overall structure during high-speed grinding. In summary, this fixture combines clamping stability, angle adjustability, and structural stability, significantly improving the precision and efficiency of diamond grinding, and providing reliable equipment support for high-quality grinding operations.
