Description

Technical Field

[0001] This utility model relates to the field of tool grinding technology, and in particular to a superhard tool grinding device. Background Technology

[0002] Tool grinding is a key process in tool manufacturing and maintenance, aiming to restore or optimize the geometry and performance of the tool's cutting edge through grinding operations. Application No. 202023136912.1 discloses a high-strength tool grinding device, including a base. A motor is fixedly installed at the center of the base's interior. Vertical rods are fixedly installed on both sides of the upper surface of the base. A screw, a second motor, and a fixing block are installed inside each vertical rod. One side of the fixing block is fixedly installed inside the vertical rod, and the other side is movably connected to the screw. The other side of the screw is connected to the second motor, and the other side of the second motor is fixedly installed at the bottom of the vertical rod. In this patent, multiple tools can be processed simultaneously by adjusting the position of the grinding disc and installing them on the vertical rod. However, this patent only allows for height adjustment of the tools, not angle adjustment, resulting in a single grinding angle that cannot adapt to different grinding needs. Therefore, we introduce a superhard tool grinding device. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A superhard tool grinding processing device includes a base 1, three support frames 2 are fixedly connected to the upper end of the base 1, a first motor 3 is fixedly connected to the upper end of each of the three support frames 2, threaded rods 6 are fixedly connected to the output ends of each of the three first motors 3, and support devices 5 are movably connected to the outer surfaces of each of the three threaded rods 6. The three support frames 2 are distributed in a ring at equal intervals. A second motor 7 is fixedly connected to the middle of the upper end of the base 1, and a grinding disc 4 is movably connected to the output end of the second motor 7.

[0025] In this embodiment, the support device 5 includes a movable frame 51, an adjusting frame 52 is movably connected to the right end of the movable frame 51, a tool body 53 is movably connected inside the adjusting frame 52, an extension frame 56 is fixedly connected to the front of the right end of the movable frame 51, the extension frame 56 has an "L" shaped structure, a first connecting shaft 54 ​​is fixedly connected to the right end of the extension frame 56, an electric push rod 55 is movably connected to the outer surface of the first connecting shaft 54; the telescopic end of the electric push rod 55 is movably connected to the front end of the adjusting frame 52; a mounting hole 511 is opened at the rear of the right end of the movable frame 51; A second connecting shaft 524 is fixedly connected to the upper left end of the section frame 52. Two frames 522 are fixedly connected to the upper end of the adjusting frame 52. Both frames 522 are "U" shaped structures. Bolts 521 are threaded to the upper end of both frames 522. Pressure plates 523 are fixedly connected to the lower end of both bolts 521. The second connecting shaft 524 is movably connected to the mounting hole 511 through a bearing. The tool body 53 is located inside the two frames 522. The movable frame 51 is slidably connected to the support frame 2 and threaded to the threaded rod 6.

[0026] It should be noted that this utility model describes a superhard tool grinding device. Three support frames 2 are evenly distributed and maintain a reasonable distance from each other to ensure stable support of the working parts above during grinding, preventing swaying or displacement due to uneven force, thus ensuring smooth grinding operations. At the upper end of each support frame 2, a primary motor 3 is precisely installed. These primary motors 3 serve as power sources, possessing powerful torque output and precise speed control capabilities. When a primary motor 3 is started, its output shaft drives the connected threaded rod 6 at high speed. Stable rotation is achieved through the installation of support devices 5 on the three threaded rods 6. These support devices 5 possess flexible movement characteristics, allowing them to move up and down along the axial direction of the threaded rods 6 as they rotate. Each support device 5 is equipped with a tool body 53. The up-and-down movement of the support devices 5 enables precise height adjustment of the three tool bodies 53. In actual operation, the operator can adjust the height according to the position of the grinding disc 4 and the grinding requirements of the tool. The support device 5 consists of three main parts: a movable frame 51, an extension frame 56, and an adjustment frame 52. The tool body 53 is securely mounted on the adjusting frame 52 to ensure that it does not loosen or shift during grinding. To achieve precise grinding of different positions on the tool body 53, an electric push rod 55 is movably connected to the extension frame 56. When the electric push rod 55 is activated, its telescopic end extends and retracts according to a preset program. Since the telescopic end of the electric push rod 55 is movably connected to the adjusting frame 52, this telescopic movement generates a force that causes the adjusting frame 52 to move around its connection point with the movable frame 51. The rotation causes the tool body 53 mounted on the adjustment frame 52 to adjust its angle. By precisely controlling the extension and retraction speed of the electric push rod 55, the operator can flexibly adjust the angle of the tool body 53 so that it can contact the grinding disc 4 in different postures. This allows for comprehensive and fine grinding of different positions of the tool body 53. This angle adjustment function not only improves the flexibility of tool grinding but also effectively ensures that the grinding quality of each part of the tool is uniform and consistent, significantly improving processing accuracy and efficiency, and providing a strong guarantee for the production of high-quality tool products.
