Description

Technical Field

[0001] This utility model relates to the field of disc grinding wheel processing technology, specifically, to a clamping device for disc grinding wheel processing. Background Technology

[0002] The processing of disc-shaped grinding wheels follows a core process of "raw material pretreatment - molding - curing - precision machining - quality inspection." Different processes revolve around ensuring the accuracy of the wheel shape, uniformity of hardness, and grinding performance. Specific processes and key points are as follows: 1. Raw material preparation: Abrasives (such as corundum or silicon carbide, which determine grinding hardness), binders (resin / ceramic powder, for bonding), and fillers (to adjust density) are mixed according to the formula. After precise measurement using a mixing device, the mixture is stirred evenly to create a fluid mixture with suitable flowability. 2. Pressing and molding: The mixture is poured into a special disc-shaped mold and pressed out into a disc-shaped blank using a hydraulic press (pressure adjusted according to the grinding wheel specifications). The blank's thickness, diameter, and center hole position must conform to the design to avoid subsequent deformation. 3. Curing Treatment: Resin-bonded grinding wheels are placed in a curing oven and heated according to a "heating-holding-cooling" curve (usually 80-150℃) to allow the resin to fully cross-link and cure, enhancing the strength of the blank. Ceramic-bonded grinding wheels require high-temperature sintering (800-1200℃) to melt the ceramic binder and bond it with the abrasive to form a hard structure. 4. Shaping: The cured blank is dressed on a lathe / grinding machine, precisely machining the dish-shaped curved surface and chamfering the edges, calibrating the center hole (to ensure coaxiality during installation), and ensuring that the grinding wheel shape meets the usage standards. 5. Sharpening Treatment: The grinding wheel surface is "sharpened" with a special dressing wheel to remove excess binder from the surface, exposing the tips of the abrasive particles, improving subsequent grinding and cutting capabilities (avoiding "dulling" of the grinding wheel leading to low grinding efficiency). 6. Quality Inspection: The outer diameter, thickness, and flatness of the grinding wheel are inspected (to ensure smooth rotation). Sampling tests are conducted on hardness (using a hardness tester) and strength (impact resistance), and products with out-of-tolerance dimensions or unqualified performance are rejected.

[0003] Existing disc grinding wheels require clamping components for sharpening. However, existing clamping components are not convenient for clamping and fixing disc grinding wheels with different hole sizes. Furthermore, when the disc grinding wheel rotates to sharpen, the clamping device is not stable enough, resulting in uneven sharpening and affecting the quality of subsequent use. Therefore, a clamping device for disc grinding wheel processing is needed to solve the above problems. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a clamping device for processing disc-shaped grinding wheels, including a processing table 1, with several support legs 101 fixedly connected to the bottom end of the processing table 1, a lifting component 2 at the top end of the processing table 1, a rotating component 3 at the top end of the processing table 1, a clamping component 4 at the top end of the rotating component 3, and a disc-shaped grinding wheel body 5 at the outer end of the clamping component 4. The disc-shaped grinding wheel body 5 has a central hole 501 in the middle. By placing the disc-shaped grinding wheel body 5 at the outer end of the clamping component 4, the lifting component 2 drives the clamping component 4 to clamp and fix the disc-shaped grinding wheel. At this time, the rotating component 3 can drive the disc-shaped grinding wheel body 5 to rotate, which facilitates the sharpening during the rotation process. Therefore, this device, through the cooperation of the clamping component 4 and the lifting component 2, can clamp and fix the central holes 501 of different diameters and the disc-shaped grinding wheel bodies 5 of different models, which can make the sharpening of the disc-shaped grinding wheel body 5 more uniform and stable, and avoid affecting the subsequent use quality.

[0021] As one implementation method in this embodiment, such as Figure 2 As shown, the rotating assembly 3 includes a motor 301, which is fixedly installed at the bottom of the processing table 1. A rotating rod 302 is installed at the output end of the motor 301. A circular plate 303 is fixedly connected to the top of the rotating rod 302. A straight groove 304 is opened at the top of the circular plate 303. A partition plate 305 is fixedly connected to the middle of the straight groove 304. In practice, by starting the motor 301, the rotating rod 302 and the circular plate 303 are driven to rotate. At this time, the butterfly grinding wheel body 5 can rotate together. The rotation speed of the butterfly grinding wheel is controlled so that it does not rotate too fast, thereby facilitating the sharpening of the butterfly grinding wheel body 5.

[0022] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the clamping assembly 4 includes a fixing rod 401, which is fixedly connected between the left and right sides inside the straight groove 304. Two springs 402 are sleeved on the outer end of the fixing rod 401, and two sleeve plates 403 are sleeved on the outer end of the fixing rod 401. One end of each spring 402 is fixedly connected to the left and right sides inside the straight groove 304, and the other end of each spring 402 is fixedly connected to the side end of each sleeve plate 403. A clamping plate 404 is fixedly connected to the top of each sleeve plate 403, and an arc-shaped plate 406 is fixedly connected to the top of each clamping plate 404. The side ends of each clamping plate 404 are arc-shaped, and several anti-slip particles 405 are fixedly connected to the side ends of each clamping plate 404. A central hole 501 is also included. The device is fitted between the outer ends of two clamping plates 404. During implementation, when the lifting assembly 2 controls the two clamping plates 404 to unfold, their side ends press against the inner side of the central hole 501. After the anti-slip particles 405 press against the inner side of the central hole 501, the anti-slip performance of the clamping plates 404 against the inner wall of the central hole 501 is improved, and the clamping and fixing effect and clamping stability of the clamping plates 404 on the butterfly grinding wheel body 5 are improved. At this time, when the sleeve plate 403 moves, the pressure spring 402 retracts. During the opening process of the sleeve plate 403 and the clamping plates 404, the central holes 501 of different diameters and the butterfly grinding wheel bodies 5 of different models can be clamped and fixed. Therefore, this device can make the butterfly grinding wheel body 5 sharpen more evenly and stably, avoiding affecting the subsequent use quality.

[0023] As one implementation method in this embodiment, such as Figure 2As shown, the lifting assembly 2 includes a cylinder 201, which is fixedly installed on the top of the processing table 1. A top plate 202 is installed on the telescopic end of the cylinder 201. A limiting plate 203 is fixedly connected to the top of the processing table 1. A limiting plate 204 is inserted inside the limiting plate 203. The top of the limiting plate 204 is fixedly connected to the bottom of the top plate 202. A rubber conical rod 205 is rotatably installed at the bottom of the top plate 202. In practice, the center hole 501 of the disc grinding wheel body 5 is first aligned with the two clamping plates 404 of the clamping assembly 4, and the center hole 501 is fitted onto the outer ends of the two clamping plates 404. At this time, the cylinder 201 is activated to drive the top plate 202 to move downward. The limiting plate 204 moves downward along the limiting plate 203. When the top plate 202 moves downward, it drives the rubber conical rod 205 to move downward until the rubber conical rod 205 contacts the space between the two clamping plates 404. When the arc plate 406 is in place, as the rubber conical rod 205 moves downward, its diameter increases. At this point, the rubber conical rod 205 gradually pushes against the two clamping plates 404, causing them to open. The sides of the two clamping plates 404 can then press against the inner side of the central hole 501. The anti-slip particles 405, pressing against the inner side of the central hole 501, improve the anti-slip properties of the clamping plates 404 against the inner wall of the central hole 501, thus improving the clamping and fixing effect and stability of the disc-shaped grinding wheel body 5. When the sleeve plate 403 moves, the pressure spring 402 contracts. During the opening process of the sleeve plate 403 and the clamping plates 404, different diameter central holes 501 and different models of disc-shaped grinding wheel bodies 5 can be clamped and fixed. Therefore, this device enables the disc-shaped grinding wheel body 5 to have a more uniform and stable cutting edge, avoiding any impact on subsequent use quality.

[0024] Working principle: In use, first align the center hole 501 of the butterfly grinding wheel body 5 with the two clamping plates 404 of the clamping assembly 4, and fit the center hole 501 onto the outer ends of the two clamping plates 404. At this time, the starting cylinder 201 drives the top plate 202 to move downward, and the limiting plate 204 moves downward along the limiting empty plate 203. When the top plate 202 moves downward, it drives the rubber conical rod 205 to move downward until the rubber conical rod 205 contacts the arc plate 406 between the two clamping plates 404. As the rubber conical rod 205 continues to move downward, the diameter of the rubber conical rod 205 becomes larger and larger. At this time, the rubber conical rod 205 will gradually push against the two clamping plates 404 and open them up. The side ends of the two clamping plates 404 can then press against the inner side of the center hole 501. After the anti-slip particles 405 press against the inner side of the center hole 501, they can improve the anti-slip performance of the clamping plates 404 against the inner wall of the center hole 501. The clamping plate 404 effectively holds and fixes the butterfly grinding wheel body 5, ensuring its stability. When the sleeve plate 403 moves, the spring 402 contracts. During the opening of the sleeve plate 403 and clamping plate 404, different diameter center holes 501 and different models of butterfly grinding wheel bodies 5 can be clamped and fixed. Therefore, this device allows the butterfly grinding wheel body 5 to be sharpened more evenly and stably, avoiding any impact on subsequent use quality. Furthermore, since the rubber conical rod 205 is made of rubber, it increases the friction between the rubber conical rod 205 and the clamping plate 404 when pressed between them. Finally, by starting the motor 301, the rotating rod 302 and the circular plate 303 rotate. At this point, the butterfly grinding wheel body 5 and the rubber conical rod 205 can rotate together. The rotation speed of the butterfly grinding wheel is controlled to prevent it from rotating too fast, thus facilitating the sharpening of the butterfly grinding wheel body 5.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
