Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically to a diamond-set grinding wheel. Background Technology

[0002] Diamond grinding wheels are tools used for shaping and dressing grinding wheels in mass production of profile grinding. They are used to shape and dress ordinary ceramic grinding wheels on a grinding machine. After the grinding wheel is dressed, the workpiece is ground, thereby copying the shape and precision dimensions of the diamond grinding wheel onto the surface of the workpiece to be processed.

[0003] A search revealed a utility model patent with Chinese patent publication number CN217728390U, which discloses a diamond grinding wheel, including a grinding wheel body and a heat dissipation assembly. The heat dissipation assembly includes a heat dissipation plate connected to the grinding wheel body, and the heat dissipation plate has a cavity for storing coolant. The heat dissipation plate has a liquid outlet hole that communicates with the cavity. This application enables the diamond grinding wheel to be cooled during use.

[0004] Although this device cools the diamond grinding wheel during use, the grinding wheel is mostly a single piece. When the grinding layer wears down to a certain extent, the entire grinding wheel needs to be replaced, resulting in a lot of material waste and increased costs. Utility Model Content

[0005] The purpose of this utility model is to provide a diamond-embedded grinding wheel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: an inlaid diamond grinding wheel, comprising: a grinding wheel base, the grinding wheel base being disc-shaped, with multiple oblique mounting grooves arranged in an array on its outer peripheral side; an inlay assembly, the inlay assembly being mounted on the grinding wheel base, the inlay assembly comprising multiple wedges and multiple diamond sheets, the diamond sheets being welded to one side of the wedges, and the diamond sheets being adapted to the oblique mounting grooves; and a fastening assembly, the fastening assembly being mounted on the grinding wheel base, which is used to fix the inlay assembly.

[0007] Furthermore, the grinding wheel base is provided with a plurality of positioning grooves, and the plurality of wedges are respectively inserted into the plurality of positioning grooves.

[0008] Furthermore, the fastening assembly includes a limiting ring, multiple connecting plates, and multiple fastening bolts. The grinding wheel base has an annular groove, and the wedge has a slot. The limiting ring engages with the slot and is inserted into the annular groove. The multiple connecting plates are arranged in an array and fixedly installed on the top of the limiting ring. One end of each connecting plate is fixed to the grinding wheel base by the fastening bolts.

[0009] Furthermore, the number of inclined mounting grooves on the grinding wheel base 1 is 60-100, and the distance between two adjacent inclined mounting grooves is 5-15mm.

[0010] Furthermore, the ends of the plurality of diamond sheets are welded to the back of the grinding wheel substrate.

[0011] Furthermore, the grinding wheel base is provided with weight-reducing grooves.

[0012] Furthermore, the grinding wheel base has a mounting hole at its center, and multiple ventilation openings are constructed on the grinding wheel base between every two diamond wafers.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses a fastening assembly to fix the inlaid assembly. When the grinding wheel is working, once the diamond sheet wears to the scrap limit, simply release the fastening assembly from the inlaid assembly and pull out the wedge and diamond sheet at an angle to replace the grinding unit separately, while preserving the intact grinding wheel base for continued use. This overcomes the problem of material waste and increased costs caused by the wear of the grinding layer of an integral grinding wheel, which results in the entire wheel being scrapped.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, an embodiment of the present invention provides an inlaid diamond grinding wheel, comprising: a grinding wheel base 1, wherein the grinding wheel base 1 is disc-shaped and has multiple oblique mounting grooves 2 arranged in an array on its outer peripheral side surface;

[0022] The inlay assembly 3 is mounted on the grinding wheel base 1. The inlay assembly 3 includes a plurality of wedges 31 and a plurality of diamond sheets 32. The diamond sheets 32 are welded to one side of the wedges 31 and are adapted to the inclined mounting groove 2.

[0023] Fastening component 4 is mounted on the grinding wheel base 1 and is used to fix the inlay component 3.

[0024] First, the diamond sheet 32 ​​is brazed to one side of the wedge 31 to form an inlaid assembly 3 with a grinding edge. Then, the entire assembly is inserted into the inclined mounting grooves 2 arranged in an array on the outer circumferential side of the disc-shaped grinding wheel base 1. At this time, the outer edge of the diamond sheet 32 ​​is exposed at the groove opening to form a continuous grinding ring. The fastening assembly 4 is installed on the end face of the grinding wheel base 1 and applies a continuous clamping force to the wedge 31 by radial clamping or axial locking to prevent the inlaid assembly 3 from loosening due to centrifugal force during high-speed rotation. The inlaid assembly 3 is fixed by the fastening assembly 4. When the grinding wheel is working, once the diamond sheet 32 ​​wears to the scrap limit, it is only necessary to release the fastening assembly 4 from the inlaid assembly 3 and pull out the wedge 31 and the diamond sheet 32 ​​in an inclined direction to replace the grinding unit separately, while the intact grinding wheel base 1 is retained for continued use. This overcomes the problem of material waste and increased cost caused by the wear of the grinding layer of the integral grinding wheel, which results in the overall scrapping.

[0025] like Figure 4 As shown, in some embodiments, the grinding wheel base 1 is provided with a plurality of positioning grooves 5, and the plurality of wedges 31 are respectively inserted into the plurality of positioning grooves 5.

[0026] The grinding wheel base 1 extends radially inward to form a positioning groove 5 at the bottom of each inclined mounting groove 2. The slope of the groove is consistent with the angle of the inclined mounting groove 2. During assembly, the narrow end of the wedge 31 is aligned with the entrance of the positioning groove 5 and pushed in obliquely until the tail end face of the wedge 31 fits against the stop face of the positioning groove 5 to achieve radial and circumferential dual positioning. Then, the fastening assembly 4 presses the wedge 31 and the diamond sheet 32 ​​together through the end face.

[0027] like Figure 4 As shown, in some embodiments, the fastening assembly 4 includes a limiting ring 41, a plurality of connecting plates 42, and a plurality of fastening bolts 43. The grinding wheel base 1 is provided with an annular groove 6, and the wedge block 31 is provided with a slot. The limiting ring 41 is engaged with the slot and inserted into the annular groove 6. The plurality of connecting plates 42 are arranged in an array and fixedly installed on the top of the limiting ring 41. One end of the plurality of connecting plates 42 is fixed to the grinding wheel base 1 by the fastening bolts 43.

[0028] The slot on the inner edge of the top surface of the wedge 31 is connected to the annular groove 6 opened on the end face of the grinding wheel base 1. The limiting ring 41 is pressed into the annular groove 6 and simultaneously inserted into the slots of all the wedges 31. Then, the connecting plate 42 of the annular array is welded or riveted to the top of the limiting ring 41. Finally, the fastening bolt 43 is inserted and tightened into the threaded hole on the end face of the grinding wheel base 1. The wedge 31, diamond sheet 32 ​​and grinding wheel base 1 are firmly combined into one unit by the limiting fixation of the connecting plate 42 and the limiting ring 41.

[0029] like Figure 2 As shown, in some embodiments, the number of inclined mounting grooves 2 on the grinding wheel base 1 is 60-100, and the distance between two adjacent inclined mounting grooves 2 is 5-15mm.

[0030] By precisely setting the number of inclined mounting grooves 2 on the outer circumferential side of the grinding wheel base 1 to 60–100, and maintaining the circumferential spacing between adjacent grooves at 5–15 mm, a high-density diamond sheet arrangement 32 can be achieved while ensuring structural strength. When the number of grooves is set to the upper limit of 100 and the spacing is 5 mm, the maximum number of grinding units can be obtained on a limited outer circumferential arc length, significantly improving the grinding efficiency per unit time and reducing the load on a single abrasive grain. This method is suitable for precision grinding with high efficiency and low roughness requirements.

[0031] like Figure 3 As shown, in some embodiments, the ends of the plurality of diamond sheets 32 are welded to the back of the grinding wheel substrate 1.

[0032] To ensure that the diamond wafers 32 not only rely on the mechanical locking of the wedge block 31 and the inclined mounting groove 2 during high-speed grinding, but also obtain a stronger axial fixing force, the tail ends of each diamond wafer 32 are further extended to the back of the grinding wheel base 1. A continuous and dense metallurgical weld is formed with the back of the base through laser cladding or high-frequency brazing. When replacement is required, the back weld is first partially melted with a rapid heating gun, and then the fastening bolts 43 are loosened and the wedge block 31 and diamond wafers 32 are pulled out according to the aforementioned steps, so as to achieve reversible disassembly. This not only retains the high reliability of the integral welded grinding wheel, but also retains the maintainability of the inlaid structure, further reducing the material consumption and downtime of each replacement.

[0033] like Figure 3 As shown, in some embodiments, the grinding wheel base 1 is provided with a weight-reducing groove 7.

[0034] By removing non-load-bearing materials through the weight-reduction groove 7, the overall mass is reduced, thereby reducing the moment of inertia and bearing load during high-speed rotation, increasing the critical speed and reducing motor power consumption.

[0035] like Figure 2 As shown, in some embodiments, the grinding wheel base 1 has a mounting hole at its center, and the grinding wheel base 1 has a plurality of ventilation openings located between every two diamond sheets 32.

[0036] The grinding wheel base 1 has a cylindrical mounting hole at its center for high-precision torque transmission with the machine tool spindle. The ventilation port is used to quickly remove grinding heat, reduce the temperature of the contact area between the diamond sheet 32 ​​and the workpiece, and extend the life of the abrasive grains.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
