Description

Technical Field

[0001] This utility model relates to the field of diamond grinding disc technology, and in particular to a segmented diamond grinding disc adapted to irregularly shaped workpieces. Background Technology

[0002] Diamond grinding discs are grinding tools made by fixing diamond particles onto a matrix with a binder. Their core function is to grind, polish, and finish high-hardness materials. They achieve efficient cutting by leveraging the high hardness of diamond and are suitable for applications such as construction, stone processing, machinery manufacturing, and decoration.

[0003] In existing technologies, the contact surface between the diamond grinding disc and the workpiece is a flat surface. When grinding irregularly shaped workpieces, it is difficult to flexibly adjust the disc to ensure effective and comprehensive contact, which affects the grinding effect. Furthermore, if the grinding disc tilts under pressure during grinding and this tilt is not detected in time, it is susceptible to breakage due to external forces, posing a significant safety hazard. Therefore, this invention designs a segmented diamond grinding disc adapted to irregularly shaped workpieces. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a segmented diamond grinding disc that is adapted to irregularly shaped workpieces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A segmented diamond grinding disc adapted to irregularly shaped workpieces includes a grinding disc and a diamond coating. The diamond coating is disposed on the lower surface of the grinding disc. The outer surface of the grinding disc is arc-shaped. The inner wall of the grinding disc has a threaded groove. A mounting ring is fixedly connected to the top of the grinding disc. An annular groove is formed on the inner wall of the mounting ring. An elastic rubber ring is fixedly connected to the inner wall of the annular groove. A fixing ring is fixedly connected to the inner wall of the elastic rubber ring. A support rod is slidably disposed on the inner wall of the fixing ring. A movable plate is fixedly connected to the rod wall below the fixing ring. A cavity is formed on the inner wall of the grinding disc. The movable plate is slidably disposed on the inner wall of the cavity. A sliding groove is formed on the inner wall of the grinding disc. A moving rod is slidably disposed on the inner wall of the sliding groove. A lever is fixedly connected to the rod wall of the moving rod. A strip-shaped opening is formed on the inner wall of the movable plate. The lever is slidably disposed on the inner wall of the strip-shaped opening.

[0007] Preferably, the inner wall of the top of the grinding disc has an opening, and a fluorescent strip is fixedly connected to the wall of the moving rod.

[0008] Preferably, the strip opening is inclined, and the movable plate at both ends of the strip opening is set as concave surfaces.

[0009] Preferably, a guide block is fixedly connected to the side wall of the movable plate, and a guide groove is provided on the inner wall of the cavity of the grinding disc, and the guide block is slidably disposed on the inner wall of the guide groove.

[0010] Preferably, the grinding disc is fixedly connected to the inner wall of the cavity with an elastic metal strip, and the top end of the elastic metal strip is pressed against the bottom of the movable plate.

[0011] Preferably, a washer is fixedly connected at the connection between the top wall of the support rod and the elastic rubber ring.

[0012] Compared with the prior art, this utility model provides a segmented diamond grinding disc adapted to irregularly shaped workpieces, which has the following beneficial effects:

[0013] 1. This segmented diamond grinding disc, adapted for irregularly shaped workpieces, utilizes the arc-shaped design of its outer surface to allow the diamond coating to better conform to the irregular surface of the workpiece, achieving segmented grinding and improving grinding accuracy and adaptability. The grinding disc is installed at the output end of the grinding equipment via the threaded groove on its inner wall. The mounting ring at the top of the grinding disc is used for auxiliary positioning. The elastic rubber ring in the annular groove on the inner wall of the mounting ring cooperates with the fixing ring to provide initial positioning for the support rod. The top of the support rod connects to the corresponding structure of the grinding equipment, further enhancing the stability of the grinding disc after installation.

[0014] 2. This segmented diamond grinding disc, adapted for irregularly shaped workpieces, allows for easy adjustment if the grinding disc shifts during use. The elastic rubber ring, under pressure, pushes the support rod to slide. The support rod moves downwards along the inner wall of the fixed ring, causing the movable plate to move. At this point, the lever slides along the slotted opening on the inner wall of the movable plate. The slotted opening is tilted, and during its downward movement, it compresses the lever, causing it to move to the right along the slot, thus pushing the moving rod along the inner wall of the groove until the fluorescent strip reaches the inner wall of the opening. This alerts the operator that the grinding disc has shifted, allowing for timely adjustments, improving work safety, and reducing potential hazards.

[0015] 3. This segmented diamond grinding disc, adapted for irregularly shaped workpieces, slides along the guide groove on the inner wall of the cavity via a guide block on the side wall of the movable plate, providing precise guidance for the movement of the movable plate and preventing deviation. When the movable plate moves downward, it compresses the elastic metal strip fixed on the inner wall of the grinding disc cavity, generating elastic potential energy. When the movable plate moves upward, the elastic metal strip releases its elastic potential energy to assist in resetting. The washer ring on the top wall of the support rod enhances the fit with the elastic rubber ring, reducing wobbling caused by installation gaps. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Reference Figure 1-3 A segmented diamond grinding disc adapted to irregularly shaped workpieces includes a grinding disc 1 and a diamond coating 2. The diamond coating 2 is disposed on the lower surface of the grinding disc 1. The outer surface of the grinding disc 1 is arc-shaped. The inner wall of the grinding disc 1 has a threaded groove. The top of the grinding disc 1 is fixedly connected to a mounting ring 3. The inner wall of the mounting ring 3 has an annular groove. The inner wall of the annular groove is fixedly connected to an elastic rubber ring 4. The inner wall of the elastic rubber ring 4 is fixedly connected to a fixing ring 5. The inner wall of the fixing ring 5 is slidably provided with a support rod 6. The rod wall of the support rod 6 located below the fixing ring 5 is fixedly connected to a movable plate 7. The inner wall of the grinding disc 1 has a cavity. The movable plate 7 is slidably disposed on the inner wall of the cavity. The inner wall of the grinding disc 1 has a sliding groove. The inner wall of the sliding groove is slidably provided with a moving rod 8. The rod wall of the moving rod 8 is fixedly connected to a lever 9. The inner wall of the movable plate 7 has a strip-shaped opening. The lever 9 is slidably disposed on the inner wall of the strip-shaped opening.

[0023] An opening is provided on the inner wall of the top of the grinding disc 1. A fluorescent strip 10 is fixedly connected to the rod wall of the moving rod 8. The strip opening is set at an angle, and the movable plate 7 is set as a concave surface at both ends of the strip opening.

[0024] When the grinding disc is in use, the arc design of the outer side of the grinding disc 1 allows the diamond coating 2 to better fit the irregular surface of the irregular workpiece, realizing segmented grinding, improving grinding accuracy and adaptability. The grinding disc 1 is installed at the output end of the grinding equipment through the threaded groove on the inner wall of the grinding disc 1. The mounting ring 3 at the top of the grinding disc 1 is used for auxiliary positioning. The elastic rubber ring 4 in the annular groove on the inner wall of the mounting ring 3 cooperates with the fixing ring 5 to play a preliminary limiting role for the support rod 6. The top of the support rod 6 is connected to the corresponding structure of the grinding equipment, further improving the stability of the grinding disc 1 after installation.

[0025] If the grinding disc 1 shifts during use, the elastic rubber ring 4 will be squeezed and push the support rod 6 to slide. The support rod 6 will move down along the inner wall of the fixed ring 5 and push the movable plate 7 to move. At this time, the lever 9 will slide along the strip opening on the inner wall of the movable plate 7. The inclined setting of the strip opening will squeeze the lever 9 to move to the right along the strip opening during the downward movement, thereby pushing the moving rod 8 to slide along the inner wall of the slide groove until the fluorescent strip 10 moves to the inner wall of the opening. This can warn the staff that the grinding disc 1 has shifted, so that the staff can adjust it in time, improve work safety and reduce safety hazards.

[0026] During the grinding process, the diamond coating 2 serves as the core grinding structure, contacting the surface of the irregularly shaped workpiece for grinding. The elastic deformation of the elastic rubber ring 4 can adapt to the slight displacement of the support rod 6, which can play a certain energy absorption and buffering role, further improving the stability of the grinding process, ensuring uniform grinding effect, and meeting the grinding requirements of irregularly shaped workpieces.

[0027] Example 2

[0028] Reference Figure 1-3 A guide block 11 is fixedly connected to the side wall of the movable plate 7. A guide groove is provided on the inner wall of the cavity of the grinding disc 1. The guide block 11 is slidably disposed on the inner wall of the guide groove. An elastic metal strip 12 is fixedly connected to the inner wall of the cavity of the grinding disc 1. The top end of the elastic metal strip 12 is tightly disposed at the bottom of the movable plate 7. A washer ring 13 is fixedly connected at the connection between the top wall of the support rod 6 and the elastic rubber ring 4.

[0029] The guide block 11 on the side wall of the movable plate 7 slides along the guide groove on the inner wall of the cavity, providing precise guidance for the movement of the movable plate 7 and avoiding deviation. When the movable plate 7 moves downward, it will compress the elastic metal strip 12 fixed on the inner wall of the grinding disc 1 cavity, and the elastic metal strip 12 will generate elastic potential energy. When the movable plate 7 moves upward, the elastic metal strip 12 releases elastic potential energy to assist in resetting. The washer ring 13 on the top wall of the support rod 6 enhances the fit with the elastic rubber ring 4 and reduces the shaking caused by the installation gap.
